These guidelines have been developed for practitioners who insert catheters and for persons responsible for surveillance
and control of infections in hospital, outpatient, and home health-care settings. This report was prepared by a working
group comprising members from professional organizations representing the disciplines of critical care medicine, infectious
diseases, health-care infection control, surgery, anesthesiology, interventional radiology, pulmonary medicine, pediatric medicine,
and nursing. The working group was led by the Society of Critical Care Medicine (SCCM), in collaboration with the
Infectious Disease Society of America (IDSA), Society for Healthcare Epidemiology of America (SHEA), Surgical Infection Society
(SIS), American College of Chest Physicians (ACCP), American Thoracic Society (ATS), American Society of Critical
Care Anesthesiologists (ASCCA), Association for Professionals in Infection Control and Epidemiology (APIC), Infusion
Nurses Society (INS), Oncology Nursing Society (ONS), Society of Cardiovascular and Interventional Radiology (SCVIR),
American Academy of Pediatrics (AAP), and the Healthcare Infection Control Practices Advisory Committee (HICPAC) of the
Centers for Disease Control and Prevention (CDC) and is intended to replace the Guideline for Prevention of Intravascular
Device-Related Infections published in 1996. These guidelines are intended to provide evidence-based recommendations for
preventing catheter-related infections. Major areas of emphasis include 1) educating and training health-care providers who insert
and maintain catheters; 2) using maximal sterile barrier precautions during central venous catheter insertion; 3) using a
2% chlorhexidine preparation for skin antisepsis; 4) avoiding routine replacement of central venous catheters as a strategy
to prevent infection; and 5) using antiseptic/antibiotic impregnated short-term central venous catheters if the rate of infection
is high despite adherence to other strategies (i.e., education and training, maximal sterile barrier precautions, and
2% chlorhexidine for skin antisepsis). These guidelines also identify performance indicators that can be used locally by
health-care institutions or organizations to monitor their success in implementing these evidence-based recommendations.
This report provides health-care practitioners with background information and specific recommendations to reduce
the incidence of intravascular catheter-related bloodstream infections (CRBSI). These guidelines replace the
Guideline for Prevention of Intravascular Device-Related
Infections, which was published in 1996
The Guidelines for the Prevention of Intravascular
Catheter-Related Infections have been developed for
practitioners who insert catheters and for persons who are responsible for surveillance and control of infections in hospital, outpatient, and
home health-care settings. This report was prepared by a working group composed of professionals representing the disciplines
of critical care medicine, infectious diseases, health-care infection control, surgery, anesthesiology, interventional
radiology, pulmonary medicine, pediatrics, and nursing. The working group was led by the Society of Critical Care Medicine
(SCCM), in collaboration with Infectious Disease Society of America (IDSA), Society for Healthcare Epidemiology of America

American Society of Critical Care Anesthesiologists (ASCCA), Association for Professionals in Infection Control and
Epidemiology (APIC), Infusion Nurses Society (INS), Oncology Nursing Society (ONS), Society of Cardiovascular and
Interventional Radiology (SCVIR), American Academy of Pediatrics (AAP), and the Healthcare Infection Control Practices
Advisory Committee (HICPAC) of the Centers for Disease Control and Prevention (CDC). The recommendations presented in
this report reflect consensus of HICPAC and other professional organizations.
Intravascular Catheter-Related Infections in Adult and Pediatric Patients:
Intravascular catheters are indispensable in modern-day medical practice, particularly in intensive care units
(ICUs). Although such catheters provide necessary vascular access, their use puts patients at risk for local and systemic
infectious complications, including local site infection, CRBSI, septic thrombophlebitis, endocarditis, and other metastatic
infections (e.g., lung abscess, brain abscess, osteomyelitis, and endophthalmitis).
Health-care institutions purchase millions of intravascular catheters each year. The incidence of CRBSI varies
considerably by type of catheter, frequency of catheter manipulation, and patient-related factors (e.g., underlying disease and acuity
of illness). Peripheral venous catheters are the devices most frequently used for vascular access. Although the incidence of local
or bloodstream infections (BSIs) associated with peripheral venous catheters is usually low, serious infectious
complications produce considerable annual morbidity because of the frequency with which such catheters are used. However, the majority
of serious catheter-related infections are associated with central venous catheters (CVCs), especially those that are placed
in patients in ICUs. In the ICU setting, the incidence of infection is often higher than in the less acute in-patient or
ambulatory setting. In the ICU, central venous access might be needed for extended periods of time; patients can be colonized
with hospital-acquired organisms; and the catheter can be manipulated multiple times per day for the administration of
fluids, drugs, and blood products. Moreover, some catheters can be inserted in urgent situations, during which optimal attention
to aseptic technique might not be feasible. Certain catheters (e.g., pulmonary artery catheters and peripheral arterial
catheters) can be accessed multiple times per day for hemodynamic measurements or to obtain samples for laboratory
analysis, augmenting the potential for contamination and subsequent clinical infection.
The magnitude of the potential for CVCs to cause morbidity and mortality resulting from infectious complications has
been estimated in several studies (2). In the United States, 15 million CVC days (i.e., the total number of days of exposure to
CVCs by all patients in the selected population during the selected time period) occur in ICUs each year
(2). If the average rate of CVC-associated BSIs is 5.3 per 1,000 catheter days in the ICU
(3), approximately 80,000 CVC-associated BSIs occur in
ICUs each year in the United States. The attributable mortality for these BSIs has ranged from no increase in mortality in
studies that controlled for severity of illness
(4--6), to 35% increase in mortality in prospective studies that did not use this
control (7,8). Thus, the attributable mortality remains unclear. The attributable cost per infection is an estimated
$34,508--$56,000 (5,9), and the annual cost of caring for patients with CVC-associated BSIs ranges from $296 million to $2.3 billion
A total of 250,000 cases of CVC-associated BSIs have been estimated to occur annually if entire hospitals are assessed
rather than ICUs exclusively (11). In this case, attributable mortality
is an estimated 12%--25% for each infection, and the
marginal cost to the health-care system is $25,000 per episode
Therefore, by several analyses, the cost of CVC-associated BSI is substantial, both in terms of morbidity and in terms
of financial resources expended. To improve patient outcome and reduce health-care costs, strategies should be implemented
to reduce the incidence of these infections. This effort should be multidisciplinary, involving health-care professionals who
insert and maintain intravascular catheters, health-care managers who allocate resources, and patients who are capable of assisting
in the care of their catheters. Although several individual strategies have been studied and shown to be effective in
reducing CRBSI, studies using multiple strategies have not
been conducted. Thus, it is not known whether implementing
multiple strategies will have an additive effect in reducing CRBSI, but it is logical to use multiple strategies concomitantly.
Terminology and Estimates of Risk
The terminology used to identify different types of catheters is confusing, because many clinicians and researchers
use different aspects of the catheter for informal reference. A catheter can be designated by the type of vessel it occupies
(e.g., peripheral venous, central venous, or arterial); its intended life span (e.g., temporary or short-term versus permanent or
long-term); its site of insertion (e.g., subclavian, femoral, internal jugular, peripheral, and peripherally inserted central
catheter [PICC]); its pathway from skin to vessel (e.g., tunneled versus nontunneled); its physical length (e.g., long versus short);
or some special characteristic of the catheter (e.g., presence or absence of a cuff, impregnation with heparin, antibiotics
or antiseptics, and the number of lumens). To accurately define a specific type of catheter, all of these aspects should be
described (Table 1).
The rate of all catheter-related infections (including local infections and systemic infections) is difficult to
determine. Although CRBSI is an ideal parameter because it represents the most serious form of catheter-related infection, the rate of
such infection depends on how CRBSI is defined.
Health-care professionals should recognize the difference between surveillance definitions and clinical definitions.
The surveillance definitions for catheter-associated BSI includes all BSIs that occur in patients with CVCs, when other sites
of infection have been excluded (Appendix A). That is, the surveillance definition overestimates the true incidence of
CRBSI because not all BSIs originate from a catheter. Some bacteremias are secondary BSIs from undocumented sources
(e.g., postoperative surgical sites, intra-abdominal infections, and
hospital-associated pneumonia or urinary tract infections).
Thus, surveillance definitions are really definitions for catheter-associated BSIs. A more rigorous definition might include only
those BSIs for which other sources were excluded by careful examination of the patient record, and where a culture of the
catheter tip demonstrated substantial colonies of an organism identical to those found in the bloodstream. Such a clinical
definition would focus on catheter-related BSIs. Therefore, to accurately compare a health-care facility's infection rate to published
data, comparable definitions also should be used.
CDC and the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) recommend that the rate
of catheter-associated BSIs be expressed as the number of catheter associated BSIs per 1,000 CVC days
(12,13). This parameter is more useful than the rate expressed as the number of catheter-associated infections per 100 catheters (or percentage of
catheters studied), because it accounts for BSIs over time and therefore adjusts risk for the number of days the catheter is in use.
Epidemiology and Microbiology
Since 1970, CDC's National Nosocomial Infection Surveillance System (NNIS) has been collecting data on the
incidence and etiologies of hospital-acquired infections, including CVC-associated BSIs in a group of nearly 300 U.S. hospitals.
The majority of hospital-acquired BSIs are associated with the use of a CVC, with BSI rates being substantially higher
among patients with CVCs than among those without CVCs. Rates of CVC-associated BSI vary considerably by hospital
size, hospital service/unit, and type of CVC. During 1992--2001, NNIS hospitals reported ICU rates of CVC-associated
BSI ranging from 2.9 (in a cardiothoracic ICU) to 11.3 (in a neonatal nursery for infants weighing <1,000 g) BSIs per 1,000
CVC days (Table 2) (14).
The relative risk of catheter-associated BSI also has been assessed in a meta-analysis of 223 prospective studies of
adult patients (11). Relative risk of infection was best determined by analyzing rates of infection both by BSIs per 100 catheters
BSIs per 1,000 catheter days. These rates, and the NNIS-derived data, can be used as benchmarks by individual hospitals
to estimate how their rates compare with other institutions. Rates are influenced by patient-related parameters, such as severity
of illness and type of illness (e.g., third-degree burns versus postcardiac surgery), and by
catheter-related parameters, such as the condition under which the catheter was placed (e.g., elective versus urgent) and catheter type
(e.g., tunneled versus nontunneled or subclavian versus jugular).
Types of organisms that most commonly cause
hospital-acquired BSIs change over time. During 1986--1989,
coagulase-negative staphylococci, followed by Staphylococcus
aureus, were the most frequently reported causes of BSIs, accounting
for 27% and 16% of BSIs, respectively (Table 3)
(15). Pooled data from 1992 through 1999 indicate that
coagulase-negative staphylococci, followed by enterococci, are now the most frequently isolated causes of hospital-acquired BSIs
(12). Coagulase-negative staphylococci account for 37%
(12) and S. aureus account for 12.6% of reported hospital-acquired BSIs
(12). Also notable was the susceptibility pattern of
S. aureus isolates. In 1999, for the first time since NNIS has been
reporting susceptibilities, >50% of all S.
aureus isolates from ICUs were resistant to oxacillin
In 1999, enterococci accounted for 13.5% of BSIs, an increase from 8% reported to NNIS during 1986--1989.
The percentage of enterococcal ICU isolates resistant to vancomycin also is increasing, escalating from 0.5% in 1989 to 25.9%
in 1999 (12).
Candida spp. caused 8% of hospital-acquired BSIs reported to NNIS during 1986--1989
(15,16), and during 1992--1999
(12,17,18). Resistance of Candida spp. to commonly used antifungal agents is increasing. Although NNIS has not
reported the percentage of BSIs caused by nonalbicans species or fluconazole susceptibility data, other epidemiologic and clinical
data document that fluconazole resistance is an increasingly relevant consideration when designing empiric therapeutic regimens
for CRBSIs caused by yeast. Data from the Surveillance and Control of Pathogens of Epidemiologic Importance
(SCOPE) Program documented that 10% of C.
albicans bloodstream isolates from hospitalized patients were resistant to
fluconazole (17). Additionally, 48% of
Candida BSIs were caused by nonalbicans species, including
C. glabrata and C. krusei, which are more likely than
C. albicans to demonstrate resistance to fluconazole and itraconazole
Gram-negative bacilli accounted for 19% of catheter-associated BSIs during 1986--1989
(15) compared with 14% of catheter-associated BSIs during 1992--1999
(12). An increasing percentage of ICU-related isolates are caused
by Enterobacteriaceae that produce extended-spectrum ß-lactamases (ESBLs), particularly
Klebsiella pneumoniae (20). Such organisms not only are resistant to extended-spectrum cephalosporins, but also to frequently used, broad
spectrum antimicrobial agents.
Migration of skin organisms at the insertion site into the cutaneous catheter tract with colonization of the catheter tip is
the most common route of infection for peripherally inserted, short-term catheters
(21,22). Contamination of the catheter hub contributes substantially to intraluminal colonization of long-term catheters
(23--25). Occasionally, catheters might
become hematogenously seeded from another focus of infection. Rarely, infusate contamination leads to CRBSI
Important pathogenic determinants of catheter-related infection are 1) the material of which the device is made and 2)
the intrinsic virulence factors of the infecting organism. In vitro studies demonstrate that catheters made of polyvinyl chloride
or polyethylene are likely less resistant to the adherence of microorganisms than are catheters made of
Teflon®, silicone elastomer, or polyurethane
(27,28). Therefore, the majority of catheters sold in the United States are no longer made of
polyvinyl chloride or polyethylene. Some catheter materials also have surface irregularities that enhance the microbial adherence
of certain species (e.g., coagulase-negative staphylococci,
Acinetobacter calcoaceticus, and
(29--31); catheters made of these materials are especially vulnerable to microbial colonization and subsequent infection.
Additionally, certain catheter materials are more thrombogenic than others, a characteristic that also might predispose to
catheter colonization and catheter-related infection
(31,32). This association has led to emphasis on preventing
catheter-related thrombus as an additional mechanism for reducing CRBSI.
The adherence properties of a given microorganism also are important in the pathogenesis of catheter-related infection.
For example, S. aureus can adhere to host proteins (e.g., fibronectin) commonly present on catheters
(33,34). Also, coagulase-negative staphylococci adhere to polymer surfaces more readily than do other pathogens (e.g.,
Escherichia coli or S.
aureus). Additionally, certain strains of coagulase-negative staphylococci produce an extracellular polysaccharide often referred to
"slime" (35,36). In the presence of catheters, this slime potentiates the pathogenicity of coagulase-negative staphylococci
by allowing them to withstand host defense mechanisms (e.g., acting as a barrier to engulfment and killing by
polymorphonuclear leukocytes) or by making them less susceptible to antimicrobial agents (e.g., forming a matrix that binds antimicrobials
before their contact with the organism cell wall)
(37). Certain Candida spp., in the presence of glucose-containing fluids,
might produce slime similar to that of their bacterial counterparts, potentially explaining the increased proportion of BSIs caused
by fungal pathogens among patients receiving parenteral nutrition fluids
Strategies for Prevention of Catheter-Related Infections in Adult
and Pediatric Patients
Quality Assurance and Continuing Education
Measures to minimize the risk for infection associated with intravascular therapy should strike a balance between
patient safety and cost effectiveness. As knowledge, technology, and health-care settings change, infection control and
prevention measures also should change. Well-organized programs that enable health-care providers to provide, monitor, and evaluate
care and to become educated are critical to the success of this effort. Reports spanning the past two decades have
consistently demonstrated that risk for infection declines following standardization of aseptic care
(39--43), and that insertion and maintenance of intravascular catheters by inexperienced staff might increase the risk for catheter colonization and
CRBSI (43,44). Specialized "IV teams" have shown unequivocal effectiveness in reducing the incidence of catheter-related
infections and associated complications and costs
(45--47). Additionally, infection risk increases with nursing staff reductions below
a critical level (48).
Site of Catheter Insertion
The site at which a catheter is placed influences the subsequent risk for catheter-related infection and phlebitis.
The influence of site on the risk for catheter infections is related in
part to the risk for thrombophlebitis and density of local skin flora.
Phlebitis has long been recognized as a risk for infection. For adults, lower extremity insertion sites are associated with
a higher risk for infection than are upper extremity sites
(49--51). In addition, hand veins have a lower risk for phlebitis than
do veins on the wrist or upper arm (52).
The density of skin flora at the catheter insertion site is a major risk factor for CRBSI. Authorities recommend that CVCs
be placed in a subclavian site instead of a jugular or femoral site to reduce the risk for infection. No randomized trial
satisfactorily has compared infection rates for catheters placed in jugular, subclavian, and femoral sites. Catheters inserted into an
internal jugular vein have been associated with higher risk for infection than those inserted into a subclavian or femoral
Femoral catheters have been demonstrated to have relatively high colonization rates when used in adults
(55). Femoral catheters should be avoided, when possible, because they are associated with a higher risk for deep venous thrombosis than
are internal jugular or subclavian catheters
(56--60) and because of a presumption that such catheters are more likely to
become infected. However, studies in pediatric patients have demonstrated that femoral catheters have a low incidence of
mechanical complications and might have an equivalent infection rate to that of nonfemoral catheters
(61--63). Thus, in adult patients, a subclavian site is preferred for infection control purposes, although other factors (e.g., the potential for
mechanical complications, risk for subclavian vein stenosis, and catheter-operator skill) should be considered when deciding where
to place the catheter. In a meta-analysis of eight studies, the use of bedside ultrasound for the placement of CVCs
substantially reduced mechanical complications compared with the standard landmark placement technique (relative risk [RR] = 0.22;
95% confidence interval [CI] = 0.10--0.45)
(64). Consideration of comfort, security, and maintenance of asepsis as well as
patient-specific factors (e.g., preexisting catheters, anatomic deformity, and bleeding diathesis), relative risk of
mechanical complications (e.g., bleeding and pneumothorax), the availability of bedside ultrasound, and the risk for infection
should guide site selection.
Type of Catheter Material
Teflon® or polyurethane catheters have been associated with
fewer infectious complications than catheters made of
polyvinyl chloride or polyethylene
(27,65,66). Steel needles used as an alternative to catheters for peripheral venous access have the
same rate of infectious complications as do
Teflon® catheters (67,68). However, the use of steel needles frequently is complicated
by infiltration of intravenous (IV) fluids into the subcutaneous tissues, a potentially serious complication if the infused fluid is
a vesicant (68).
Hand Hygiene and Aseptic Technique
For short peripheral catheters, good hand hygiene before catheter insertion or maintenance, combined with proper
aseptic technique during catheter manipulation, provides protection against infection. Good hand hygiene can be achieved
through the use of either a waterless, alcohol-based product
(69) or an antibacterial soap and water with adequate rinsing
(70). Appropriate aseptic technique does not necessarily require sterile gloves; a new pair of disposable nonsterile gloves can be
used in conjunction with a "no-touch" technique for the insertion of peripheral venous catheters. However, gloves are required
by the Occupational Safety and Health Administration as standard precautions for the prevention of bloodborne
Compared with peripheral venous catheters, CVCs carry a substantially greater risk for infection; therefore, the level
of barrier precautions needed to prevent infection during insertion of CVCs should be more stringent. Maximal sterile
barrier precautions (e.g., cap, mask, sterile gown, sterile gloves, and large sterile drape) during the insertion of CVCs
substantially reduces the incidence of CRBSI compared with standard precautions (e.g., sterile gloves and small drapes)
(22,71). Although the efficacy of such precautions for insertion of PICCs and midline catheters has not been studied, the use of maximal
barrier precautions also is probably applicable to PICCs.
In the United States, povidone iodine has been the most widely used antiseptic for cleansing arterial catheter and
CVC- insertion sites (72). However, in one study, preparation of central venous and arterial sites with a 2% aqueous
chlorhexidine gluconate lowered BSI rates compared with site preparation with 10% povidone-iodine or 70% alcohol
(73). Commercially available products containing chlorhexidine have not been available until recently; in July 2000, the U.S. Food and
Drug Administration (FDA) approved a 2% tincture of chlorhexidine preparation for skin antisepsis. Other preparations
of chlorhexidine might not be as effective. Tincture of chlorhexidine gluconate 0.5% is no more effective in preventing CRBSI
or CVC colonization than 10% povidone iodine, as demonstrated by a prospective, randomized study of adults
(74). However, in a study involving neonates, 0.5% chlorhexidine reduced peripheral IV colonization compared with povidone iodine
(20/418 versus 38/408 catheters; p = 0.01)
(75). This study, which did not include CVCs, had an insufficient number
of participants to assess differences in BSI rates. A 1% tincture of chlorhexidine preparation is available in Canada and
Australia, but not yet in the United States. No published trials have compared a 1% chlorhexidine preparation to povidone-iodine.
Catheter Site Dressing Regimens
Transparent, semipermeable polyurethane dressings have become a popular means of dressing catheter insertion
sites. Transparent dressings reliably secure the device, permit continuous visual inspection of the catheter site, permit patients
to bathe and shower without saturating the dressing, and require less frequent changes than do standard gauze and tape
dressings; the use of these dressings saves personnel time.
In the largest controlled trial of dressing regimens on peripheral catheters, the infectious morbidity associated with the use
of transparent dressings on approximately 2,000 peripheral catheters was examined
(65). Data from this study suggest that the rate of colonization among catheters dressed with transparent dressings (5.7%) is comparable to that of those dressed
with gauze (4.6%) and that no clinically substantial differences exist in either the incidences of catheter-site colonization
or phlebitis. Furthermore, these data suggest that transparent dressings can be safely left on peripheral venous catheters for
the duration of catheter insertion without increasing the risk for thrombophlebitis
A meta-analysis has assessed studies that compared the risk for catheter-related BSIs for groups using transparent
dressings versus groups using gauze dressing
(76). The risk for CRBSIs did not differ between the groups. The choice of dressing can
be a matter of preference. If blood is oozing from the catheter insertion site, gauze dressing might be preferred.
In a multi-center study, a chlorhexidine-impregnated sponge
(Biopatch) placed over the site of short-term arterial
and CVCs reduced the risk for catheter colonization and CRBSI
(77). No adverse systemic effects resulted from use of this device.
Catheter Securement Devices
Sutureless securement devices can be advantageous over suture in preventing catheter-related BSIs. One study,
which involved only a limited number of patients and was underpowered, compared a sutureless device with suture for
the securement of PICCS; in this study, CRBSI was reduced in the group of patients that received the sutureless device
In-line filters reduce the incidence of infusion-related phlebitis
(79,80). No data support their efficacy in
preventing infections associated with intravascular catheters and infusion systems. Proponents of filters cite several potential benefits
to using these filters, including 1) reducing the risk for infection from contaminated infusate or proximal contamination
(i.e., introduced proximal to the filter); 2) reducing the risk for phlebitis in patients who require high doses of medication or
in those in whom infusion-related phlebitis already has occurred; 3) removing particulate matter that might contaminate
IV fluids (81); and 4) filtering endotoxin produced by gram-negative organisms in contaminated infusate
(82). These theoretical advantages should be tempered by the knowledge that infusate-related BSI is rare and that filtration of medications or
infusates in the pharmacy is a more practical and less costly way to remove the majority of particulates. Furthermore, in-line
filters might become blocked, especially with certain solutions (e.g., dextran, lipids, and mannitol), thereby increasing the number
of line manipulations and decreasing the availability of administered drugs
(83). Thus, for reducing the risk for CRBSI, no
strong recommendation can be made in favor of using in-line filters.
Antimicrobial/Antiseptic Impregnated Catheters and Cuffs
Certain catheters and cuffs that are coated or impregnated with antimicrobial or antiseptic agents can decrease the risk
for CRBSI and potentially decrease hospital costs associated with treating CRBSIs, despite the additional acquisition cost of
an antimicrobial/antiseptic impregnated catheter
(84). All of the studies involving antimicrobial/antiseptic impregnated
catheters have been conducted using triple-lumen, noncuffed catheters in adult patients whose catheters remained in place <30
days. Although all of the studies have been conducted in adults, these catheters have been approved by FDA for use in
patients weighing >3 kg. No antiseptic or antimicrobial impregnated catheters currently are available for use in weighing <3 kg.
Chlorhexidine/Silver sulfadiazine. Catheters coated with chlorhexidine/silver sulfadiazine only on the external
luminal surface have been studied as a means to reduce CRBSI. Two meta-analyses
(2,85) demonstrated that such catheters reduced
the risk for CRBSI compared with standard noncoated catheters. The mean duration of catheter placement in one
meta-analysis ranged from 5.1 to 11.2 days
(86). The half-life of antimicrobial activity against
S. epidermidis is 3 days in vitro for
catheters coated with chlorhexidine/silver sulfadiazine; this antimicrobial activity decreases over time
(87). The benefit for the patients who receive these catheters will be realized within the first 14 days
(86). A second-generation catheter is now available
with chlorhexidine coating both the internal and external luminal surfaces. The external surface has three times the amount
of chlorhexidine and extended release of the surface bound antiseptics than that in the first generation catheters. The
external surface coating of chlorhexidine is combined with silver-sulfadiazine, and the internal surface is coated with
chlorhexidine alone. Preliminary studies indicate that prolonged anti-infective activity provides improved efficacy in preventing
infections (88). Although rare, anaphylaxis has been reported with the use of these chlorhexidine/silver sulfadiazine catheters in
Japan (89). Whether patients will become colonized or infected with organisms resistant to chlorhexidine/silver sulfadiazine has
not been determined (86).
Chlorhexidine/silver sulfadiazine catheters are more expensive than standard catheters. However, one analysis has
suggested that the use of chlorhexidine/silver sulfadiazine catheters should lead to a cost savings of $68 to $391 per catheter
(90) in settings in which the risk for CRBSI is high despite adherence to other preventive strategies (e.g., maximal barrier
and aseptic techniques). Use of these catheters might be cost effective in ICU patients, burn patients, neutropenic patients,
and other patient populations in which the rate of infection exceeds 3.3 per 1,000 catheter days
Minocycline/Rifampin. In a multicenter randomized trial, CVCs impregnated on both the external and internal
surfaces with minocycline/rifampin were associated with lower rates of CRBSI when compared with the first-generation
chlorhexidine-silver sulfadiazine impregnated catheters
(91). The beneficial effect began after day 6 of catheterization. None of the
catheters were evaluated beyond 30 days. No minocycline/rifampin-resistant organisms were reported. However, in vitro data
indicate that these impregnated catheters could increase the incidence of minocycline and rifampin resistance among
pathogens, especially staphylococci. The half-life of antimicrobial activity against
S. epidermidis is 25 days with catheters coated
with minocycline/rifampin, compared with 3 days for the first-generation catheters coated with chlorhexidine/silver sulfadiazine
in vitro (87). In vivo, the duration of antimicrobial activity of the minocycline/rifampin catheter is longer than that of the
first-generation chlorhexidine/silver sulfadiazine catheter
(91). No comparative studies have been published using the
second-generation chlorhexidine/ silver sulfadiazine catheter. Studies are needed to evaluated whether the improved performance
of the minocyline/rifampin catheters results from the antimicrobial agents used or from the coating of both the internal
and external surfaces. As with chlorhexidine/silver sulfadiazine catheters, some clinicians have recommended that the
minocycline/rifampin catheters be considered in patient populations when the rate of CRBSI exceeds 3.3 per 1,000 catheter days
(86). Others suggest that reducing all rates of CRBSI should be the goal
(92). The decision to use chlorhexidine/silver
sulfadiazine or minocycline/rifampin impregnated catheters should be based on the need to enhance prevention of CRBSI after
standard procedures have been implemented (e.g., educating personnel, using maximal sterile barrier precautions, and using
2% chlorhexidine skin antisepsis) and then balanced against the concern for
emergence of resistant pathogens and the cost of implementing
Platinum/Silver. Ionic metals have broad antimicrobial
activity and are being used in catheters and cuffs to prevent
CRBSI. A combination platinum/silver impregnated catheter is available in Europe and has recently been approved by FDA for use
in the United States. Although these catheters are being marketed for their antimicrobial properties, no published
studies have been presented to support an antimicrobial effect.
Silver cuffs. Ionic silver has been used in subcutaneous collagen cuffs attached to CVCs
(93). The ionic silver provides antimicrobial activity and the cuff provides a mechanical barrier to the migration of microorganisms along the external
surface of the catheter. In studies of catheters left in place
>20 days, the cuff failed to reduce the incidence of CRBSI
(94,95). Two other studies of short-term catheters could not demonstrate efficacy because of the minimal number of CRBSIs
Systemic Antibiotic Prophylaxis
No studies have demonstrated that oral or parenteral antibacterial or antifungal drugs might reduce the incidence of
CRBSI among adults (97--99). However, among low birth weight infants, two studies have assessed vancomycin prophylaxis;
both demonstrated a reduction in CRBSI but no reduction in mortality
(100,101). Because the prophylactic use of vancomycin
is an independent risk factor for the acquisition of vancomycin-resistant enterococcus (VRE)
(102), the risk for acquiring VRE likely outweighs the benefit of using prophylactic vancomycin.
Povidone-iodine ointment applied at the insertion site of hemodialysis catheters has been studied as a
prophylactic intervention to reduce the incidence of catheter-related infections. One randomized study of 129 hemodialysis
catheters demonstrated a reduction in the incidence of exit-site infections, catheter-tip colonization, and BSIs with the routine use
of povidone-iodine ointment at the catheter insertion site compared with no ointment at the insertion site
Several studies have evaluated the effectiveness of mupirocin ointment applied at the insertion sites of CVCs as a means
to prevent CRBSI (104--106). Although mupirocin reduced the risk for CRBSI
(106), mupirocin ointment also has been associated
with mupirocin resistance (107,108), and might adversely affect the integrity of polyurethane catheters
Nasal carriers of S. aureus have a higher risk for acquiring CRBSI than do noncarriers
(103,111). Mupirocin ointment has been used intranasally to decrease nasal carriage of
S. aureus and lessen the risk for CRBSI. However, resistance to
mupirocin develops in both S. aureus and coagulase-negative staphylococci soon after routine use of mupirocin is instituted
Other antibiotic ointments applied to the catheter insertion site also have been studied and have yielded conflicting
results (112--114). In addition, rates of catheter colonization with
Candida spp. might be increased with the use of
antibiotic ointments that have no fungicidal activity
(112,114). To avoid compromising the integrity of the catheter, any ointment that
is applied to the catheter insertion site should be checked against the catheter and ointment manufacturers'
recommendations regarding compatibility.
Antibiotic Lock Prophylaxis
To prevent CRBSI, antibiotic lock prophylaxis has been attempted by flushing and filling the lumen of the catheter with
an antibiotic solution and leaving the solution to dwell in the lumen of the catheter. Three studies have demonstrated
the usefulness of such prophylaxis in neutropenic patients with long-term catheters
(115--117). In two of the studies, patients received either heparin alone (10 U/ml) or heparin plus 25 micrograms/ml of vancomycin. The third study
compared vancomycin/ciprofloxacin/heparin (VCH) to vancomycin/heparin (VH)and then to heparin alone. The rate of CRBSI
with vancomycin-susceptible organisms was significantly lower (VCH p = 0.022; VH p = 0.028) and the time to the first episode
of bacteremia with vancomycin-susceptible organisms was substantially longer (VCH p = 0.036; VH p = 0.011) in
patients receiving either vancomycin/ciprofloxacin/heparin or vancomycin/heparin compared with heparin alone
(115--117). One study involving a limited number of children revealed no difference in rates of CRBSI between children receiving a
heparin flush compared with those receiving heparin and vancomycin
(118). However, because the use of vancomycin is
an independent risk factor for the acquisition of VRE
(102), this practice is not recommended routinely.
An anticoagulant/antimicrobial combination comprising minocycline and ethylenediaminetetraraacetic acid (EDTA)
has been proposed as a lock solution because it has antibiofilm and antimicrobial activity against gram-positive,
gram-negative, and Candida organisms
(119), as well as anticoagulant properties. However, no controlled or randomized trials
have demonstrated its efficacy.
Anticoagulant flush solutions are used widely to prevent catheter thrombosis. Because thrombi and fibrin deposits
on catheters might serve as a nidus for microbial colonization of intravascular catheters
(120,121), the use of anticoagulants might have a role in the prevention of CRBSI.
In a meta-analysis evaluating the benefit of heparin prophylaxis (3 U/ml in TPN, 5,000 U every 6 or 12 hours flush,
or 2,500 U low molecular weight heparin subcutaneously) in patients with short-term CVCs, the risk for catheter-related
central venous thrombosis was reduced with the use of prophylactic heparin
(122). However, no substantial difference in the rate
for CRBSI was observed. Because the majority of heparin solutions contain preservatives with antimicrobial activity, whether
any decrease in the rate of CRBSI is a result of the reduced thrombus formation, the preservative, or both is unclear.
The majority of pulmonary artery, umbilical, and central venous catheters are available with a heparin-bonded coating.
The majority are heparin-bonded with benzalkonium chloride, which provides the catheters with antimicrobial activity
(123) and provides an anti-thrombotic effect
Warfarin also has been evaluated as a means for reducing CRBSI by reducing thrombus formation on catheters
(125,126). In patients with long-term CVCs, low-dose warfarin (i.e., 1 mg/day) reduced the incidence of catheter thrombus. No
data demonstrate that warfarin reduces the incidence of CRBSI.
Replacement of Catheters
Peripheral Venous Catheters
Scheduled replacement of intravascular catheters has been proposed as a method to prevent phlebitis and
catheter-related infections. Studies of short peripheral venous catheters indicate that the incidence of thrombophlebitis and
bacterial colonization of catheters increases when catheters are left in place >72 hours
(66,67,127). However, rates of phlebitis are
not substantially different in peripheral catheters left in place 72 hours compared with 96 hours
(128). Because phlebitis and catheter colonization have been associated with an increased risk for catheter-related infection, short peripheral catheter
commonly are rotated at 72--96-hour intervals to reduce both the risk for infection and patient discomfort associated
Midline catheters have been associated with lower rates of phlebitis than short peripheral catheters and with lower rates
of infection than CVCs (129--131). In one prospective study of 140 midline catheters, their use was associated with a BSI rate
of 0.8 per 1,000 catheter-days (131). No specific risk factors, including duration of catheterization, were associated
with infection. Midline catheters were in place a median of 7 days, but for as long as 49 days. Although the findings of this
study suggested that midline catheters can be changed only when there is a specific indication, no prospective, randomized
studies have assessed the benefit of routine replacement as a strategy to prevent CRBSI associated with midline catheters.
CVCs, Including PICCs and Hemodialysis Catheters
Catheter replacement at scheduled time intervals as a method to reduce CRBSI has not lowered rates. Two trials
have assessed a strategy of changing the catheter every 7 days compared with a strategy of changing catheters as needed
(132,133). One of these studies involved 112 surgical ICU patients needing CVCs, pulmonary artery catheters, or peripheral
arterial catheters (132), whereas the other study involved only subclavian hemodialysis catheters
(133). In both studies, no difference in CRBSI was observed in patients undergoing scheduled catheter replacement every 7 days compared with patients
whose catheters were replaced as needed.
Scheduled guidewire exchanges of CVCs is another proposed strategy for preventing CRBSI. The results of a
meta-analysis of 12 randomized controlled trials assessing CVC management failed to prove any reduction of CRBSI rates through
routine replacement of CVCs by guidewire exchange compared with catheter replacement on an as-needed basis
(134). Thus, routine replacement of CVCs is not necessary for catheters that are functioning and have no evidence of causing local or
Catheter replacement over a guidewire has become an accepted technique for replacing a malfunctioning catheter
or exchanging a pulmonary artery catheter for a CVC when invasive monitoring no longer is needed. Catheter insertion over
a guidewire is associated with less discomfort and a significantly lower rate of mechanical complications than are
those percutaneously inserted at a new site
(135); in addition, this technique provides a means of preserving limited venous access
in some patients. Replacement of temporary catheters over a guidewire in the presence of bacteremia is not an
acceptable replacement strategy, because the source of infection is usually colonization of the skin tract from the insertion site to the
vein (22,135). However, in selected patients with tunneled hemodialysis catheters and bacteremia, catheter exchange over
a guidewire, in combination with antibiotic therapy, might be an alternative as a salvage strategy in patients with limited
venous access (136--139).
The use of catheters for hemodialysis is the most common factor contributing to bacteremia in dialysis patients
(140,141). The relative risk for bacteremia in patients with dialysis catheters is sevenfold the risk for patients with primary
arteriovenous fistulas (142). Despite the National Kidney Foundation's effort to reduce the number of hemodialysis patients maintained
with catheter access, catheter use increased from 12.7% in 1995 to 22.2% in 1999
(143). Rates for bacteremia per 100 patient months were 0.2 for arteriovenous fistulas, 0.5 for grafts, 5.0 for cuffed catheters, and 8.5 for noncuffed catheters
(CDC, unpublished data, 1999).
To reduce the rate of infection, hemodialysis catheters should be avoided in favor of arteriovenous fistulas and grafts.
If temporary access is needed for dialysis, a cuffed catheter is preferable to a noncuffed catheter, even in the ICU setting, if
the catheter is expected to stay in place for >3 weeks
Pulmonary Artery Catheters
Pulmonary artery catheters are inserted through a
Teflon® introducer and typically remain in place an average of 3 days.
The majority of pulmonary artery catheters are heparin bonded, which reduces not only catheter thrombosis but also
microbial adherence to the catheter (145). Meta-analysis indicates that standard nonheparin-bonded pulmonary artery catheter rates
CRBSI are 5.5 per 1,000 catheter days; for heparin-bonded pulmonary artery catheters, this rate is 2.6 per 1,000 catheter
days (11). Because the majority of pulmonary artery catheters are heparin-bonded, the relative risk of infection with these
catheters is similar to that of CVC (2.6 versus 2.3 per 1,000 catheter days)
A prospective study of 442 pulmonary artery catheters demonstrated an increased risk for CRBSI after 5 days (0/442
CRBSI before 5 days versus 5/442 CSBSI after 5 days; p < 0.001)
(146). A prospective observational study of 71 pulmonary
artery catheters demonstrated higher infection rates in catheters left in place longer than 7 days (2% before 7 days versus 16% after
7 days; p = 0.056) (147). However, no studies indicate that catheter replacement at scheduled time intervals is an
effective method to reduce CRBSI (132,135). In patients who continue to require hemodynamic monitoring, pulmonary
artery catheters do not need to be changed more frequently than every 7 days. No specific recommendation can be made
regarding routine replacement of catheters that need to be in place for >7 days.
Pulmonary artery catheters are usually packaged with a thin plastic sleeve that prevents touch contamination when
placed over the catheter. In a study of 166 catheters, patients who were randomly assigned to have their catheters
self-contained within this sleeve had a reduced risk for CRBSI compared with those who had a pulmonary artery catheter placed without
the sleeve (p = 0.002) (148).
Peripheral Arterial Catheters
Peripheral arterial catheters are usually inserted into the radial or femoral artery and permit continuous blood
pressure monitoring and blood gas measurements. The rate of CRBSI is comparable to that of temporary CVCs (2.9 versus 2.3
per 1,000 catheter days) (11). One study of peripheral arterial catheters demonstrated no difference in infection rates
between changing catheters at scheduled times and changing arterial catheters on an as-needed basis
(132). One observational study of 71 arterial catheters revealed that 10 local infections and four CRBSIs occurred in patients who had peripheral
arterial catheters in place for >4 days compared with one local infection and no CRBSIs in patients whose catheters were in place
<4 days (p < 0.05) (147). Because the risk for CRBSI is likely similar to that of short-term CVCs, arterial catheters can
be approached in a similar way. No specific recommendation can be made regarding replacement of catheters that need to be
in place for >5 days.
Replacement of Administration Sets
The optimal interval for routine replacement of IV administration sets has been examined in three well-controlled
studies. Data from each of these studies reveal that replacing administration sets no more frequently than 72 hours after initiation
of use is safe and cost-effective (149--151). Data from a more recent study demonstrated that rates of phlebitis were
not substantially different if administration sets were left in place 96 hours compared with 72 hours
(128). When a fluid that enhances microbial growth is infused (e.g., lipid emulsions and blood products), more frequent changes of administration
sets are indicated, because these products have been identified as independent risk factors for CRBSI
Stopcocks (used for injection of medications, administration of IV infusions, and collection of blood samples) represent
a potential portal of entry for microorganisms into vascular access catheters and IV fluids. Stopcock contamination is
common, occurring in 45% and 50% in the majority of series. Whether such contamination is a substantial entry point of CRBSI
has been difficult to prove.
"Piggyback" systems are used as an alternative to stopcocks. However, they also pose a risk for contamination of
the intravascular fluid if the device entering the rubber membrane of an injection port is exposed to air or comes into
direct contact with nonsterile tape used to fix the needle to the port. Modified piggyback systems have the potential to
prevent contamination at these sites (159).
Needleless Intravascular Catheter Systems
Attempts to reduce the incidence of sharp injuries and the resultant risk for transmission of bloodborne infections to
health-care workers have led to the design and introduction of needleless infusion systems. When the devices are used according
to manufacturers' recommendations, they do not substantially affect the incidence of CRBSI
Multidose Parenteral Medication Vials
Parenteral medications commonly are dispensed in multidose, parenteral medication vials that might be used for
prolonged periods for one or more patients. Although the overall risk for extrinsic contamination of multidose vials is likely
minimal (168), the consequences of contamination might result in life-threatening infection
(169,170). Single-use vials are frequently preservative-free and might pose a risk for contamination if they are punctured several times.
Special Considerations for Intravascular Catheter-Related Infections
in Pediatric Patients
Prevention of CRBSI in children requires additional considerations, although only certain studies have been
performed specifically in children. Pediatric data have been derived largely from studies in neonatal or pediatric ICUs and
pediatric oncology patients.
As in adults, the majority of BSIs in children are associated with the use of an intravascular catheter. From 1995
through 2000, the pooled mean catheter-associated BSI rate for all pediatric ICUs reporting data to NNIS was 7.7 per 1,000
catheter days (171,172). Umbilical catheter and CVC-associated BSI rates for neonatal ICUs ranged from 11.3 per 1,000 catheter
days in children with birth weight <1,000 g to 4.0 per 1,000 catheter days in children whose birth weight was >2,500 g
(171). Catheter utilization rates were comparable in adult and pediatric ICUs
As in adults, the majority of CRBSIs in children are caused by coagulase-negative staphylococci. During 1992--1999,
these bacteria accounted for 37.7% of BSIs in pediatric ICUs reporting to NNIS
(12). Exposure to lipids has been identified as
an independent risk factor for development of coagulase-negative staphylococcal bacteremia in very low birth weight infants
(i.e., those weighing <1,000 g) (odds ratio [OR] = 9.4; 95% CI = 1.2--74.2)
(155), as well as candidemia in the neonatal ICU
(OR = 5.33; 95% CI = 1.23--48.4) (154). Gram-negative bacteria accounted for 25% of BSIs reported in pediatric ICUs
(172), whereas enterococci and
Candida spp. accounted for 10% and 9%, respectively
Peripheral Venous Catheters
As in adults, the use of peripheral venous catheters in pediatric patients might be complicated by phlebitis,
infusion extravasation, and catheter infection
(174). Catheter location, infusion of parenteral nutritional fluids with continuous
IV lipid emulsions, and length of ICU stay before catheter insertion have all increased pediatric patients' risk for
phlebitis. However, contrary to the risk in adults, the risk for phlebitis in children has not increased with the duration of
Peripheral Arterial Catheters
In a prospective study of 340 peripheral arterial catheters in children, the following two risk factors for
catheter-related infection were identified: 1) use of an arterial system that permitted backflow of blood into the pressure tubing and
2) duration of catheterization (176). Although a correlation was found between duration of arterial catheterization and risk
for catheter colonization, the risk remained constant for 2--20 days at 6.2%
Although the umbilical stump becomes heavily colonized soon after birth, umbilical-vessel catheterization often is used
for vascular access in newborn infants. Umbilical vessels can be cannulated easily and permit both collection of blood samples
and measurement of hemodynamic status. The incidences of catheter colonization and BSI are similar for umbilical vein
catheters and umbilical artery catheters. In several studies, an estimated 40%--55% of umbilical artery catheters were colonized and
5% resulted in CRBSI; umbilical vein catheters were associated with colonization in 22%--59% of cases
(177--179) and with
CRBSI in 3%--8% of cases (178). Although CRBSI rates are similar for umbilical catheters in the high position (i.e., above
the diaphragm) compared with the low position (i.e., below the diaphragm and above the aortic bifurcation), catheters placed
in the high position result in a lower incidence of vascular complications without an increase in adverse sequelae
Risk factors for infection differ for umbilical artery and umbilical vein catheters. In one study, neonates with very low
birth weight who also received antibiotics for
>10 days were at increased risk for umbilical artery CRBSIs
(178). In comparison, those with higher birth weight and receipt of parenteral nutrition fluids were at increased risk for umbilical vein
CRBSI. Duration of catheterization was not an independent risk factor for infection of either type of umbilical catheter.
Because of the limited vascular sites in children, attention should be given to the frequency with which catheters are
replaced in these patients. In a study in which survival analysis techniques were used to examine the relation between the duration
of central venous catheterization and complications in pediatric ICU patients, all of the patients studied (n = 397)
remained uninfected for a median of 23.7 days
(180). In addition, no relation was found between duration of catheterization and
the daily probability of infection (r = 0.21; p > 0.1), suggesting that routine replacement of CVCs likely does not reduce
the incidence of catheter-related infection
Catheter Site Care
Although data regarding the use of the chlorhexidine-impregnated sponge
(Biopatch) in children are limited,
one randomized, controlled study involving 705 neonates reported a substantial decrease in colonized catheter tips in infants in
the Biopatch group compared with the group that had standard dressings (15% versus 24%; RR = 0.6; 95% CI = 0.5--0.9),
but no difference in the rates of CRBSI or BSI without a source.
Biopatch was associated with localized contact dermatitis
in infants of very low birth weight. Of 98 neonates with very low birth weight, 15 (15%) developed localized contact
dermatitis; four (1.5%) of 237 neonates weighing >1,000 g developed this reaction (p < 0.0001). Infants with gestational age <26
weeks who had CVCs placed at age <8 days were at increased risk for having localized contact dermatitis, whereas no infants in
the control group developed this local reaction
Performance indicators for reducing CRBSI are 1) implementation of educational programs that include didactic
and interactive components for those who insert and maintain catheters; 2) use of maximal sterile barrier precautions
during catheter placement; 3) use of chlorhexidine for skin antisepsis; and 4) rates of catheter discontinuation when the catheter is
no longer essential for medical management. The impact these recommendations will have on individual institutions should
be evaluated using specific performance indicators.
Recommendations for Placement
of Intravascular Catheters in Adults and Children
These recommendations are designed to reduce the infectious complications associated with intravascular catheter
use. Recommendations should be considered in the context of the institution's experience with catheter-related
infections, experience with other adverse catheter-related complications (e.g., thrombosis, hemorrhage, and pneumothorax),
and availability of personnel skilled in the placement of intravascular devices. Recommendations are provided for 1)
intravascular-catheter use in general; 2) specific devices; and 3) special circumstances (i.e., intravascular-device use in pediatric patients
and CVC use for parenteral nutrition and hemodialysis access). Recommendations regarding the frequency of replacing
catheters, dressings, administration sets, and fluids also are provided (Appendix B).
As in previous guidelines issued by CDC and HICPAC, each recommendation is categorized on the basis of
existing scientific data, theoretical rationale, applicability, and economic impact. The CDC/HICPAC system for
categorizing recommendations is as follows:
Category IA. Strongly recommended for implementation and strongly supported by well-designed experimental, clinical,
or epidemiologic studies.
Category IB. Strongly recommended for implementation and supported by some experimental, clinical, or
epidemiologic studies, and a strong theoretical rationale.
Category IC. Required by state or federal regulations, rules, or standards.
Category II. Suggested for implementation and supported by suggestive clinical or epidemiologic studies or a
Unresolved issue. Represents an unresolved issue for which evidence is insufficient or no consensus regarding efficacy exists.
I. Health-care worker education and training
A. Educate health-care workers regarding the indications for intravascular catheter use, proper procedures for
the insertion and maintenance of intravascular catheters, and appropriate infection-control measures to
prevent intravascular catheter-related infections
(39,43,45--47,182--187). Category IA
B. Assess knowledge of and adherence to guidelines periodically for all persons who insert and manage
intravascular catheters (39,43,46,182,188).
C. Ensure appropriate nursing staff levels in ICUs to minimize the incidence of CRBSIs
(48,189,190). Category IB
A. Monitor the catheter sites visually or by palpation through the intact dressing on a regular basis, depending on
the clinical situation of individual patients. If patients have tenderness at the insertion site, fever without obvious
source, or other manifestations suggesting local or BSI, the dressing should be removed to allow thorough examination
of the site (1,191--193). Category IB
III. Hand hygiene

and water or with waterless alcohol-based gels or foams. Observe hand hygiene before and after palpating
catheter insertion sites, as well as before and after inserting, replacing, accessing, repairing, or dressing an
intravascular catheter. Palpation of the insertion site should not be performed after the application of antiseptic, unless
aseptic technique is maintained
(43,70,196--200). Category IA
IV. Aseptic technique during catheter insertion and care

and Health Administration Bloodborne Pathogens Standard.
Category IC. Wearing clean gloves rather than sterile gloves
is acceptable for the insertion of peripheral intravascular
catheters if the access site is not touched after the application
of skin antiseptics. Sterile gloves should be worn for the insertion of arterial and central catheters
(201,203). Category IA

Do not routinely use arterial or venous cutdown procedures as a method to insert catheters
(204--206). Category IA
VI. Catheter site care
A. Cutaneous antisepsis
VII. Catheter-site dressing regimens
1. Disinfect clean skin with an appropriate antiseptic before catheter insertion and during dressing
changes. Although a 2% chlorhexidine-based preparation is preferred, tincture of iodine, an iodophor, or 70%
alcohol can be used (73,75,207,208). Category IA
2. No recommendation can be made for the use of chlorhexidine in infants aged <2 months.
3. Allow the antiseptic to remain on the insertion site and to air dry before catheter insertion. Allow
povidone iodine to remain on the skin for at least 2 minutes, or longer if it is not yet dry before insertion
(73,75,207,208). Category IB
4. Do not apply organic solvents (e.g., acetone and ether) to the skin before insertion of catheters or
during dressing changes (209). Category IA
A. Use either sterile gauze or sterile, transparent, semipermeable dressing to cover the catheter site
(146,210--212). Category IA
VIII. Selection and replacement of intravascular catheters
B. Tunneled CVC sites that are well healed might not require dressings.
C. If the patient is diaphoretic, or if the site is bleeding or oozing, a gauze dressing is preferable to a transparent,
semi-permeable dressing (146,210--212). Category II
D. Replace catheter-site dressing if the dressing becomes damp, loosened, or visibly soiled
(146,210). Category IB
E. Change dressings at least weekly for adult and adolescent patients depending on the circumstances of the
individual patient (211). Category II
F. Do not use topical antibiotic ointment or creams on insertion sites (except when using dialysis catheters) because
of their potential to promote fungal infections and antimicrobial resistance
(107,213). Category IA (See Central Venous Catheters, Including PICCs, Hemodialysis, and Pulmonary Artery Catheters, in Adult and
Pediatric Patients, Section II.I.)
G. Do not submerge the catheter under water. Showering should be permitted if precautions can be taken to reduce
the likelihood of introducing organisms into the catheter (e.g., if the catheter and connecting device are protected
with an impermeable cover during the shower
(214,215). Category II
A. Select the catheter, insertion technique, and insertion site with the lowest risk for complications (infectious
and noninfectious) for the anticipated type and duration of IV therapy
(22,55,59, 216--218). Category IA

of infection (134,135,221). Category IB
D. Replace peripheral venous catheters at least every 72--96 hours in adults to prevent phlebitis
(128). Leave peripheral venous catheters in place in children until IV therapy is completed, unless complications (e.g., phlebitis
and infiltration) occur (174,175,222,223). Category IB
E. When adherence to aseptic technique cannot be ensured (i.e., when catheters are inserted during a
medical emergency), replace all catheters as soon as possible and after no longer than
48 hours (22,71,201,202). Category II
F. Use clinical judgment to determine when to replace a catheter that could be a source of infection (e.g., do
not routinely replace catheters in patients whose only indication of infection is fever). Do not routinely replace
venous catheters in patients who are bacteremic or fungemic if the source of infection is unlikely to be the catheter
(224). Category II
G. Replace any short-term CVC if purulence is observed at the insertion site, which indicates infection
(224,225). Category IB
H. Replace all CVCs if the patient is hemodynamically unstable and CRBSI is suspected
(224,225). Category II
I. Do not use guidewire techniques to replace catheters in patients suspected of having catheter-related
infection (134,135). Category IB
A. Administration sets
X. IV-injection ports
1. Replace administration sets, including secondary sets and add-on devices, no more frequently than at
72-hour intervals, unless catheter-related infection is suspected or documented
(23, 149--151). Category IA

2. Replace tubing used to administer blood, blood products, or lipid emulsions (those combined with amino
acids and glucose in a 3-in-1 admixture or infused separately) within 24 hours of initiating the infusion
229). Category IB. If the solution contains only dextrose and amino acids, the administration set does not
need to be replaced more frequently than every 72 hours

recommendations (160,162,165,166). Category II
3. Ensure that all components of the system are compatible to minimize leaks and breaks in the system
(163). Category II
4. Minimize contamination risk by wiping the access port with an appropriate antiseptic and accessing the
port only with sterile devices (162,163,165).
1. Complete the infusion of lipid-containing solutions (e.g., 3-in-1 solutions) within 24 hours of hanging
the solution (156--158,226,229). Category IB
2. Complete the infusion of lipid emulsions alone within 12 hours of hanging the emulsion. If

(237,239). Category IA
E. If multidose vials are used
1. Refrigerate multidose vials after they are opened if recommended by the manufacturer.
2. Cleanse the access diaphragm of multidose vials with 70% alcohol before inserting a device into the vial
(236). Category IA
3. Use a sterile device to access a multidose vial and avoid touch contamination of the device before penetrating
the access diaphragm (235,240). Category IA
4. Discard multidose vial if sterility is compromised
(235,240). Category IA
Do not use filters routinely for infection-control purposes
(80,241). Category IA
XIII. IV-therapy personnel
Designate trained personnel for the insertion and maintenance of intravascular catheters
(46,47,210,242). Category IA
XIV. Prophylactic antimicrobials
Do not administer intranasal or systemic antimicrobial prophylaxis routinely before insertion or during use of
an intravascular catheter to prevent catheter colonization or BSI
(97,98,108,243). Category IA
Peripheral Venous Catheters, Including Midline Catheters, in Adult and
I. Selection of peripheral catheter
A. Select catheters on the basis of the intended purpose and duration of use, known complications (e.g., phlebitis
and infiltration), and experience of individual catheter operators
(67,68,244). Category IB
II. Selection of peripheral-catheter insertion site
B. Avoid the use of steel needles for the administration of fluids and medication that might cause tissue necrosis
if extravasation occurs (67,68). Category IA
C. Use a midline catheter or PICC when the duration of IV therapy will likely exceed 6 days
(244). Category IB
A. In adults, use an upper- instead of a lower-extremity site for catheter insertion. Replace a catheter inserted in a
lower-extremity site to an upper-extremity site as soon as possible
(67,245). Category IA
III. Catheter and catheter-site care
B. In pediatric patients, the hand, the dorsum of the foot, or the scalp can be used as the catheter insertion site.
C. Replacement of catheter
1. Evaluate the catheter insertion site daily, by palpation through the dressing to discern tenderness and
by inspection if a transparent dressing is in use. Gauze and opaque dressings should not be removed if the patient
has no clinical signs infection. If the patient has local tenderness or other signs of possible CRBSI, an opaque
dressing should be removed and the site inspected visually.
2. Remove peripheral venous catheters if the patient develops signs of phlebitis (e.g., warmth, tenderness,
erythema, and palpable venous cord), infection, or a malfunctioning catheter
(66). Category IB
3. In adults, replace short, peripheral venous catheters at least 72--96 hours to reduce the risk for phlebitis. If
sites for venous access are limited and no evidence of phlebitis or infection is present, peripheral venous catheters
can be left in place for longer periods, although the patient and the insertion sites should be closely
monitored (66,128,246). Category IB
4. Do not routinely replace midline catheters to reduce the risk for infection
(131). Category IB
5. In pediatric patients, leave peripheral venous catheters in place until IV therapy is completed, unless
a complication (e.g., phlebitis and infiltration) occurs
(174,175,222,223). Category IB
Do not routinely apply prophylactic topical
antimicrobial or antiseptic ointment or cream to the insertion site
of peripheral venous catheters (107,213). Category IA
Central Venous Catheters, Including PICCs, Hemodialysis, and Pulmonary
Artery Catheters, in Adult and Pediatric Patients
A. Conduct surveillance in ICUs and other patient populations to determine CRBSI rates, monitor trends in
those rates, and assist in identifying lapses in infection-control practices
(3,12,16,247--250). Category IA
II. General principles
B. Express ICU data as the number of catheter-associated
BSIs per 1,000 catheter-days for both adults and children
and stratify by birth weight categories for neonatal ICUs to facilitate comparisons with national data in
comparable patient populations and health-care settings
(3,12,16,247--250). Category IB
C. Investigate events leading to unexpected life-threatening
or fatal outcomes. This includes any process variation for which
a recurrence would likely present an adverse outcome
(13). Category IC
A. Use a CVC with the minimum number of ports or lumens essential for the management of the patient
(251--254). Category IB
III. Selection of catheter insertion site
B. Use an antimicrobial or antiseptic-impregnated CVC in adults whose catheter is expected to remain in place >5
days if, after implementing a comprehensive strategy to reduce rates of CRBSI, the CRBSI rate remains above the goal
set by the individual institution based on benchmark rates (Table 2) and local factors. The comprehensive strategy
should include the following three components: educating persons who insert and maintain catheters, use of maximal
barrier precautions, and a 2% chlorhexidine preparation for skin antisepsis during CVC insertion
(84--86,90,91,255). Category IB
C. No recommendation can be made for the use of impregnated catheters in children.
D. Designate personnel who have been trained and exhibit competency in the insertion of catheters to supervise
trainees who perform catheter insertion
(39,43,46,182,187,188). Category IA
E. Use totally implantable access devices for patients who require long-term, intermittent vascular access. For
patients requiring frequent or continuous access, a PICC or tunneled CVC is preferable
(256,257). Category II
F. Use a cuffed CVC for dialysis if the period of temporary access is anticipated to be prolonged (e.g., >3
weeks) (144,258). Category IB
G. Use a fistula or graft instead of a CVC for permanent access for dialysis
(142). Category IB
H. Do not use hemodialysis catheters for blood drawing or applications other than hemodialysis except during dialysis
or under emergency circumstances. Category II
I. Use povidone-iodine antiseptic ointment at the hemodialysis catheter exit site after catheter insertion and at the end
of each dialysis session only if this ointment does not interact with the material of the hemodialysis catheter
per manufacturer's recommendation
(103,114,144). Category II
A. Weigh the risk and benefits of placing a device at a recommended site to reduce infectious complications against
the risk for mechanical complications (e.g., pneumothorax, subclavian artery puncture, subclavian vein
laceration, subclavian vein stenosis, hemothorax, thrombosis, air embolism, and
(22,55,59,218). Category IA
IV. Maximal sterile barrier precautions during catheter insertion
B. Use a subclavian site (rather than a jugular or a femoral site) in adult patients to minimize infection risk
for nontunneled CVC placement (22,55,59,60).
C. No recommendation can be made for a preferred site of insertion to minimize infection risk for a nontunneled
CVC (61--63). Unresolved issue
D. Place catheters used for hemodialysis and pheresis in a jugular or femoral vein rather than a subclavian vein to
avoid venous stenosis if catheter access is needed
(259--263). Category IA
A. Use aseptic technique including the use of a cap, mask, sterile gown, sterile gloves, and a large sterile sheet,
for the insertion of CVCs (including PICCS) or guidewire exchange
(22,71). Category IA
V. Replacement of catheter
B. Use a sterile sleeve to protect pulmonary artery catheters during insertion
(148). Category IB
A. Do not routinely replace CVCs, PICCs, hemodialysis catheters, or pulmonary artery catheters to prevent
catheter-related infections (132,134,135). Category IB
VI. Catheter and catheter-site care
B. Do not remove CVCs or PICCs on the basis of fever alone. Use clinical judgment regarding the appropriateness
of removing the catheter if infection is evidenced elsewhere or if a noninfectious cause of fever is suspected
(224,264). Category II
C. Guidewire exchange
1. Do not use guidewire exchanges routinely for nontunneled catheters to prevent infection
(135,265). Category IB
2. Use a guidewire exchange to replace a malfunctioning nontunneled catheter if no evidence of infection is
present (135,265). Category IB
3. Use a new set of sterile gloves before handling the new catheter when guidewire exchanges are performed
(22,71). Category II
A. General measures
Designate one port exclusively for hyperalimen-tation if a multilumen catheter is used to administer
parenteral nutrition (266). Category II
B. Antibiotic lock solutions
Do not routinely use antibiotic lock solutions to prevent CRBSI. Use prophylactic antibiotic lock solution only
in special circumstances (e.g., in treating a patient with a long-term cuffed or tunneled catheter or port who has a
history of multiple CRBSIs despite optimal maximal adherence to aseptic technique)
(115,116,267,268). Category II
C. Catheter-site dressing regimens
1. Replace the catheter-site dressing when it becomes damp, loosened, or soiled or when inspection of the site
is necessary (65,146,211). Category IA
2. Replace dressings used on short-term CVC sites every 2 days for gauze dressings and at least every 7 days
for transparent dressings, except in those pediatric patients in which the risk for dis-lodging the catheter
outweighs the benefit of changing the dressing
(211). Category IB
3. Replace dressings used on tunneled or implanted CVC sites no more than once per week,
until the insertion site has healed (211). Category IB
4. No recommendation can be made regarding the necessity for any dressing on well-healed exit sites of
long-term cuffed and tunneled CVCs. Unresolved issue
D. No recommendation can be made for the use of chlorhexidine sponge dressings to reduce the incidence of
infection. Unresolved issue
E. Do not use chlorhexidine sponge dressings in neonates aged <7 days or of gestational age <26 weeks
(181). Category II
F. No recommendation can be made for the use of sutureless securement devices.
G. Ensure that catheter-site care is compatible with the catheter material
(109,110). Category IB
H. Use a sterile sleeve for all pulmonary artery catheters
(148). Category IB
Additional Recommendations for Peripheral Arterial Catheters and
Pressure Monitoring Devices for Adult and Pediatric Patients
I. Selection of pressure monitoring system
Use disposable, rather than reusable, transducer assemblies when possible
(269--273). Category IB
II. Replacement of catheter and pressure monitoring system
A. Do not routinely replace peripheral arterial catheters to prevent catheter-related infections
(132,147, 221,274). Category II
III. Care of pressure monitoring systems
B. Replace disposable or reusable transducers at 96-hour intervals. Replace other components of the system
(including the tubing, continuous-flush device, and flush solution) at the time the transducer is replaced
(22,270). Category IB
A. General measures
1. Keep all components of the pressure monitoring system (including calibration devices and flush solution)
sterile (269,275--277). Category IA
B. Sterilization or disinfection of pressure monitoring systems
2. Minimize the number of manipulations of and entries into the pressure monitoring system. Use a
closed-flush system (i.e., continuous flush), rather than an open system (i.e., one that requires a syringe and stopcock),
to maintain the patency of the pressure monitoring catheters
(272,278). Category II
3. When the pressure monitoring system is accessed through a diaphragm rather than a stopcock, wipe
the diaphragm with an appropriate antiseptic before accessing the system
(272). Category IA
4. Do not administer dextrose-containing solutions
or parenteral nutrition fluids through the pressure
monitoring circuit (272,279,280). Category IA
1. Use disposable transducers
(272,279--282). Category IB
2. Sterilize reusable transducers according to the manufacturers' instructions if the use of disposable transducers
is not feasible (272,279--282). Category IA
Recommendations for Umbilical Catheters
I. Replacement of catheters
A. Remove and do not replace umbilical artery catheters if any signs of CRBSI, vascular insufficiency, or thrombosis
are present (283). Category II
II. Catheter-site care
B. Remove and do not replace umbilical venous catheters if any signs of CRBSI or thrombosis are present
(283). Category II
C. No recommendation can be made for treating through an umbilical venous catheter suspected of being
infected. Unresolved issue
D. Replace umbilical venous catheters only if the catheter malfunctions.
A. Cleanse the umbilical insertion site with an antiseptic before catheter insertion. Avoid tincture of iodine because of
the potential effect on the neonatal thyroid. Other iodine-containing products (e.g., povidone-iodine) can be
used (75,177,178,284,285). Category IB
B. Do not use topical antibiotic ointment or creams on umbilical catheter insertion sites because of the potential
to promote fungal infections and antimicrobial resistance
(107,213). Category IA
C. Add low doses of heparin (0.25--1.0 F/ml) to the fluid infused through umbilical arterial catheters
(286--288). Category IB
D. Remove umbilical catheters as soon as possible when no longer needed or when any sign of vascular insufficiency
to the lower extremities is observed. Optimally, umbilical artery catheters should not be left in place >5 days
(283,289). Category II
E. Umbilical venous catheters should be removed as soon as possible when no longer needed but can be used up to
14 days if managed aseptically (290,291). Category II
* Administration sets include the area from the spike of tubing entering the fluid container to the hub of the vascular access device. However, a short extension tube
might be connected to the catheter and might be considered a portion of the catheter to facilitate aseptic technique when changing administration sets.
