Data and Statistics
Antimicrobial Use Prevalence Survey
Results of a multistate, acute care hospital antimicrobial-drug use prevalence survey are now available: Prevalence of Antimicrobial Use in US Acute Care Hospitals, May-September 2011. The purpose of this survey was to determine the prevalence of inpatient antimicrobial-drug use, the most common antimicrobial drug types, and the reasons for their use. The Digital News Release contains video links and resources on this publication. Additional information about the Emerging Infections Program Healthcare-Associated Infection and Antibiotic Use Prevalence Survey can be found at: http://www.cdc.gov/hai/eip/antibiotic-use.html.
HAI Prevalence Survey
The CDC healthcare-associated infection (HAI) prevalence survey provides an updated national estimate of the overall problem of HAIs in U.S. hospitals. Based on a large sample of U.S. acute care hospitals, the survey found that on any given day, about 1 in 25 hospital patients has at least one healthcare-associated infection. There were an estimated 722,000 HAIs in U.S acute care hospitals in 2011. About 75,000 hospital patients with HAIs died during their hospitalizations. More than half of all HAIs occurred outside of the intensive care unit.
Estimates of Healthcare-Associated Infections Occurring in Acute Care Hospitals in the United States, 2011
|Major Site of Infection||Estimated No.|
|Urinary Tract Infections||93,300|
|Primary Bloodstream Infections||71,900|
|Surgical site infections from any inpatient surgery||157,500|
|Other types of infections||118,500|
|Estimated total number of infections in hospitals||721,800|

The CDC National and State Healthcare-Associated Infections Progress Report is a report that gives a closer look at the healthcare-associated infections (HAIs) most commonly reported to CDC using the National Healthcare Safety Network (NHSN). This is an annual report that describes national and state progress in preventing central line-associated bloodstream infections, catheter-associated urinary tract infections, surgical site infections after colon surgery and surgical site infections after abdominal hysterectomy. The report is based on 2012 data.
