At a glance

Core Infection Prevention and Control Practices for Healthcare

Introduction

Adherence to infection prevention and control practices is essential to providing safe and high quality patient care across all settings where healthcare is delivered

This document concisely describes a core set of infection prevention and control practices that are required in all healthcare settings, regardless of the type of healthcare provided. The practices were selected from among existing CDC recommendations and are the subset that represent fundamental standards of care that are not expected to change based on emerging evidence or to be regularly altered by changes in technology or practices, and are applicable across the continuum of healthcare settings. The practices outlined in this document are intended to serve as a standard reference and reduce the need to repeatedly evaluate practices that are considered basic and accepted as standards of medical care. Readers should consult the full texts of CDC healthcare infection control guidelines for background, rationale, and related infection prevention recommendations for more comprehensive information.

Scope

The core practices in this document should be implemented in all settings where healthcare is delivered. These venues include both inpatient settings (e.g., acute, long-term care) and outpatient settings (e.g., clinics, urgent care, ambulatory surgical centers, imaging centers, dialysis centers, physical therapy and rehabilitation centers, alternative medicine clinics). In addition, these practices apply to healthcare delivered in settings other than traditional healthcare facilities, such as homes, assisted living communities, pharmacies, and health fairs.

Healthcare personnel (HCP) referred to in this document include all paid and unpaid persons serving in healthcare settings who have the potential for direct or indirect exposure to patients or infectious materials, including body substances, contaminated medical supplies, devices, and equipment; contaminated environmental surfaces; or contaminated air.

Methods

CDC healthcare infection control guidelines 1-17 were reviewed, and recommendations included in more than one guideline were grouped into core infection prevention practice domains (e.g., education and training of HCP on infection prevention, injection and medication safety). Additional CDC materials aimed at providing general infection prevention guidance outside of the acute care setting 18-20 were also reviewed. HICPAC formed a workgroup led by HICPAC members and including representatives of professional organizations (see Contributors in archives for full list). The workgroup reviewed and discussed all of the practices, further refined the selection and description of the core practices and presented drafts to HICPAC at public meeting and recommendations were approved by the full Committee in July 2014. In October 2022, the Core Practices were reviewed and updated by subject matter experts within the Division of Healthcare Quality Promotion at CDC. The addition of new practices followed the same methodology employed by the Core Practices Workgroup but also included review of pathogen-specific guidance documents 21-22 that were created or updated after July 2014. These additions were presented to HICPAC at the November 3, 2022 meeting. Future updates to the Core Practices will be guided by the publication of new or updated CDC infection prevention and control guidelines.

Core Practice Category Core Practices Comments
1. Leadership Support
References and resources: 1-12
  1. Ensure that the governing body of the healthcare facility or organization is accountable for the success of infection prevention activities.
  2. Allocate sufficient human and material resources to infection prevention to ensure consistent and prompt action to remove or mitigate infection risks and stop transmission of infections. Ensure that staffing and resources do not prevent nurses, environmental staff, et. al., from consistently adhering to infection prevention and control practices.
  3. Assign one or more qualified individuals with training in infection prevention and control to manage the facility’s infection prevention program.
  4. Empower and support the authority of those managing the infection prevention program to ensure effectiveness of the program.
To be successful, infection prevention programs require visible and tangible support from all levels of the healthcare facility’s leadership.
2. Education and Training of Healthcare Personnel on Infection Prevention
References and resources: 1-4, 6-8, 10-13
  1. Provide job-specific, infection prevention education and training to all healthcare personnel for all tasks.
    1. Require training before individuals are allowed to perform their duties and at least annually as a refresher.
    2. Provide additional training in response to recognized lapses in adherence and to address newly recognized infection transmission threats (e.g., introduction of new equipment or procedures).
  2. Develop processes to ensure that all healthcare personnel understand and are competent to adhere to infection prevention requirements as they perform their roles and responsibilities.
  3. Provide written infection prevention policies and procedures that are available, current, and based on evidence-based guidelines (e.g., CDC/ HICPAC, etc.).
Training should be adapted to reflect the diversity of the workforce and the type of facility, and tailored to meet the needs of each category of healthcare personnel being trained.
3. Patient, Family and Caregiver Education
References and resources: 2-5, 7-8, 10-11
  1. Provide appropriate infection prevention education to patients, family members, visitors, and others included in the caregiving network.
Include information about how infections are spread, how they can be prevented, and what signs or symptoms should prompt reevaluation and notification of the patient’s healthcare provider. Instructional materials and delivery should address varied levels of education, language comprehension, and cultural diversity
4. Performance Monitoring and Feedback
References and resources: 1-14
  1. Identify and monitor adherence to infection prevention practices and infection control requirements.
  2. Provide prompt, regular feedback on adherence and related outcomes to healthcare personnel and facility leadership.
  3. Train performance monitoring personnel and use standardized tools and definitions.
  4. Monitor the incidence of infections that may be related to care provided at the facility and act on the data and use information collected through surveillance to detect transmission of infectious agents in the facility.
Performance measures should be tailored to the care activities and the population served.
5. Standard Precautions Use Standard Precautions to care for all patients in all settings. Standard Precautions include:
5a. Hand hygiene
5b. Environmental cleaning and disinfection
5c. Injection and medication safety
5d. Risk assessment with use of appropriate personal protective equipment (e.g., gloves, gowns, face masks) based on activities being performed
5e. Minimizing Potential Exposures (e.g. respiratory hygiene and cough etiquette)
5f. Reprocessing of reusable medical equipment between each patient or when soiled
Standard Precautions are the basic practices that apply to all patient care, regardless of the patient’s suspected or confirmed infectious state, and apply to all settings where care is delivered. These practices protect healthcare personnel and prevent healthcare personnel or the environment from transmitting infections to other patients.
5a. Hand Hygiene
References and resources: 3, 7, 11
  1. Require healthcare personnel to perform hand hygiene in accordance with Centers for Disease Control and Prevention (CDC) recommendations.
  2. Use an alcohol-based hand rub or wash with soap and water for the following clinical indications:
    1. Immediately before touching a patient
    2. Before performing an aseptic task (e.g., placing an indwelling device) or handling invasive medical devices
    3. Before moving from work on a soiled body site to a clean body site on the same patient
    4. After touching a patient or the patient’s immediate environment
    5. After contact with blood, body fluids or contaminated surfaces
    6. Immediately after glove removal
  3. Ensure that healthcare personnel perform hand hygiene with soap and water when hands are visibly soiled.
  4. Ensure that supplies necessary for adherence to hand hygiene are readily accessible in all areas where patient care is being delivered.
Unless hands are visibly soiled, an alcohol-based hand rub is preferred over soap and water in most clinical situations due to evidence of better compliance compared to soap and water. Hand rubs are generally less irritating to hands and are effective in the absence of a sink.

Refer to “CDC Guideline for Hand Hygiene in Health-Care Settings” or “Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings, 2007” for additional details.

5b. Environmental Cleaning and Disinfection
References and resources: 4, 7, 10, 11, 13, 21
  1. Require routine and targeted cleaning of environmental surfaces as indicated by the level of patient contact and degree of soiling.
    1. Clean and disinfect surfaces in close proximity to the patient and frequently touched surfaces in the patient care environment on a more frequent schedule compared to other surfaces.
    2. Promptly clean and decontaminate spills of blood or other potentially infectious materials.
  2. Select EPA-registered disinfectants that have microbiocidal activity against the pathogens most likely to contaminate the patient-care environment.
  3. Follow manufacturers’ instructions for proper use of cleaning and disinfecting products (e.g., dilution, contact time, material compatibility, storage, shelf-life, safe use and disposal).
When information from manufacturers is limited regarding selection and use of agents for specific microorganisms, environmental surfaces or equipment, facility policies regarding cleaning and disinfecting should be guided by the best available evidence and careful consideration of the risks and benefits of the available options.

Refer to “CDC Guidelines for Environmental Infection Control in Health-Care Facilities” and “CDC Guideline for Disinfection and Sterilization in Healthcare Facilities” for details.

5c. Injection and Medication Safety
References and resources: 7, 11, 16-20
  1. Prepare medications in a designated clean medication preparation area that is separated from potential sources of contamination, including sinks or other water sources.
  2. Use aseptic technique when preparing and administering medications
  3. Disinfect the access diaphragms of medication vials before inserting a device into the vial
  4. Use needles and syringes for one patient only (this includes manufactured prefilled syringes and cartridge devices such as insulin pens).
  5. Enter medication containers with a new needle and a new syringe, even when obtaining additional doses for the same patient.
  6. Ensure single-dose or single-use vials, ampules, and bags or bottles of parenteral solution are used for one patient only.
  7. Use fluid infusion or administration sets (e.g., intravenous tubing) for one patient only
  8. Dedicate multidose vials to a single patient whenever possible. If multidose vials are used for more than one patient, restrict the medication vials to a centralized medication area and do not bring them into the immediate patient treatment area (e.g., operating room, patient room/cubicle)
  9. Wear a facemask when placing a catheter or injecting material into the epidural or subdural space (e.g., during myelogram, epidural or spinal anesthesia)
Refer to “Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings, 2007” for details.
5d. Risk Assessment with Appropriate Use of Personal Protective Equipment
References and resources: 7, 11, 19, 20
  1. Ensure proper selection and use of personal protective equipment (PPE) based on the nature of the patient interaction and potential for exposure to blood, body fluids and/or infectious material:
    1. Wear gloves when it can be reasonably anticipated that contact with blood or other potentially infectious materials, mucous membranes, non-intact skin, potentially contaminated skin or contaminated equipment could occur.
    2. Wear a gown that is appropriate to the task to protect skin and prevent soiling of clothing during procedures and activities that could cause contact with blood, body fluids, secretions, or excretions.
    3. Use protective eyewear and a mask, or a face shield, to protect the mucous membranes of the eyes, nose and mouth during procedures and activities that could generate splashes or sprays of blood, body fluids, secretions and excretions. Select masks, goggles, face shields, and combinations of each according to the need anticipated by the task performed.
    4. Remove and discard PPE, other than respirators, upon completing a task before leaving the patient’s room or care area. If a respirator is used, it should be removed and discarded (or reprocessed if reusable) after leaving the patient room or care area and closing the door.
    5. Do not use the same gown or pair of gloves for care of more than one patient. Remove and discard disposable gloves upon completion of a task or when soiled during the process of care.
    6. Do not wash gloves for the purpose of reuse.
  2. Ensure that healthcare personnel have immediate access to and are trained and able to select, put on, remove, and dispose of PPE in a manner that protects themselves, the patient, and others
PPE, e.g., gloves, gowns, face masks, respirators, goggles and face shields, can be effective barriers to transmission of infections but are secondary to the more effective measures such as administrative and engineering controls.

Refer to “Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings, 2007” as well as Occupational Safety and Health Administration (OSHA) requirements for details.

5e. Minimizing Potential Exposures
References and resources: 1, 7, 11, 21, 22
  1. Develop and implement systems for early detection and management (e.g., use of appropriate infection control measures, including isolation precautions, PPE) of potentially infectious persons at initial points of patient encounter in outpatient settings (e.g., triage areas, emergency departments, outpatient clinics, physician offices) and at the time of admission to hospitals and long-term care facilities (LTCF).
  2. Use respiratory hygiene and cough etiquette to reduce the transmission of respiratory infections within the facility.
  3. Prompt patients and visitors with symptoms of respiratory infection to contain their respiratory secretions and perform hand hygiene after contact with respiratory secretions by providing tissues, masks, hand hygiene supplies and instructional signage or handouts at points of entry and throughout the facility
  4. When space permits, separate patients with respiratory symptoms from others as soon as possible (e.g., during triage or upon entry into the facility).
Refer to “Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings, 2007” for details.

During periods of higher levels of community respiratory virus transmission*, facilities should consider having everyone mask upon entry to the facility to ensure better adherence to respiratory hygiene and cough etiquette for those who might be infectious. Such an approach could be implemented facility-wide or targeted toward higher risk areas (e.g., emergency departments, urgent care, units experiencing an outbreak) based on a facility risk assessment.

*Examples of potential metrics include, but are not limited to, increase in outbreaks of healthcare-onset respiratory infections, increase in emergency department or outpatient visits related to respiratory infections.

5f. Reprocessing of Reusable Medical Equipment
References and resources: 2-4, 7-8, 11-13
  1. Clean and reprocess (disinfect or sterilize) reusable medical equipment (e.g., blood glucose meters and other point-of-care devices, blood pressure cuffs, oximeter probes, surgical instruments, endoscopes) prior to use on another patient or when soiled.
    1. Consult and adhere to manufacturers’ instructions for reprocessing.
  2. Maintain separation between clean and soiled equipment to prevent cross contamination.
Manufacturer’s instructions for reprocessing reusable medical equipment should be readily available and used to establish clear operating procedures and training content for the facility. Instructions should be posted at the site where equipment reprocessing is performed. Reprocessing personnel should have training in the reprocessing steps and the correct use of PPE necessary for the task. Competencies of those personnel should be documented initially upon assignment of their duties, whenever new equipment is introduced, and periodically (e.g., annually). Additional details about reprocessing essentials for facilities can be found in HICPAC’s recommendations Essential Elements of a Reprocessing Program for Flexible Endoscopes (Essential Elements of a Reprocessing Program for Flexible Endoscopes – Recommendations of the HICPAC).

Refer to “CDC Guideline for Disinfection and Sterilization in Healthcare Facilities” for details

6. Transmission-Based Precautions
References and resources: 7, 11
  1. Implement additional precautions (i.e., Transmission-Based Precautions) for patients with documented or suspected diagnoses where contact with the patient, their body fluids, or their environment presents a substantial transmission risk despite adherence to Standard Precautions
  2. Adapt transmission-based precautions to the specific healthcare setting, the facility design characteristics, and the type of patient interaction.
  3. Implement transmission-based precautions based on the patient’s clinical presentation and likely infection diagnoses (e.g., syndromes suggestive of transmissible infections such as diarrhea, meningitis, fever and rash, respiratory infection) as soon as possible after the patient enters the healthcare facility (including reception or triage areas in emergency departments, ambulatory clinics or physicians’ offices) then adjust or discontinue precautions when more clinical information becomes available (e.g., confirmatory laboratory results).
  4. To the extent possible, place patients who may need transmission-based precautions into a single-patient room while awaiting clinical assessment.
  5. Notify accepting facilities and the transporting agency about the need for transmission-based precautions based on suspected or confirmed infections or presence of targeted multidrug-resistant pathogens when patients are transferred.
Implementation of Transmission-Based Precautions may differ depending on the patient care settings (e.g., inpatient, outpatient, long-term care), the facility design characteristics, and the type of patient interaction, and should be adapted to the specific healthcare setting.

Refer to “Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings, 2007” for details.

7. Temporary invasive Medical Devices for Clinical Management
References and resources: 8, 11
  1. During each healthcare encounter, assess the medical necessity of any invasive medical device (e.g., vascular catheter, indwelling urinary catheter, feeding tubes, ventilator, surgical drain) in order to identify the earliest opportunity for safe removal.
  2. Ensure that healthcare personnel adhere to recommended insertion and maintenance practices
Early and prompt removal of invasive devices should be part of the plan of care and included in regular assessment. Healthcare personnel should be knowledgeable regarding risks of the device and infection prevention interventions associated with the individual device, and should advocate for the patient by working toward removal of the device as soon as possible.

Refer to “CDC Guidelines for Environmental Infection Control in Health-Care Facilities” and “CDC Guideline for Disinfection and Sterilization in Healthcare Facilities” for details.

8. Occupational Health
References and resources: 1, 7, 18, 19
  1. Ensure that healthcare personnel either receive immunizations or have documented evidence of immunity against vaccine-preventable diseases as recommended by the CDC, CDC’s Advisory Committee on Immunization Practices (ACIP) and required by federal, state or local authorities.
  2. Implement processes and sick leave policies to encourage healthcare personnel to stay home when they develop signs or symptoms of acute infectious illness (e.g. fever, cough, diarrhea, vomiting, or draining skin lesions) to prevent spreading their infections to patients and other healthcare personnel.
  3. Implement a system for healthcare personnel to report signs, symptoms, and diagnosed illnesses that may represent a risk to their patients and coworkers to their supervisor or healthcare facility staff who are responsible for occupational health
  4. Adhere to federal and state standards and directives applicable to protecting healthcare workers against transmission of infectious agents including OSHA’s Bloodborne Pathogens Standard, Personal Protective Equipment Standard, Respiratory Protection standard and TB compliance directive.
It is the professional responsibility of all healthcare organizations and individual personnel to ensure adherence to federal, state and local requirements concerning immunizations; work policies that support safety of healthcare personnel; timely reporting of illness by employees to employers when that illness may represent a risk to patients and other healthcare personnel; and notification to public health authorities when the illness has public health implications or is required to be reported.
