National Healthcare Safety Network (NHSN) report: Data summary for 2006 through 2008, issued December 2009

This report is a summary of device-associated and procedure-associated module data collected and reported by hospitals participating in the National Healthcare Safety Network (NHSN) from January 2006 through December 2007 as reported to the NHSN by March 24, 2008. This report updates previously published device-associated module data from NHSN and surgical site infection (SSI) rate data from the National Nosocomial Infections Surveillance (NNIS) system. The NHSN was established in 2005 to integrate and supersede 3 legacy surveillance systems at the Centers for Disease Control and Prevention (CDC): the NNIS system, the Dialysis Surveillance Network (DSN), and the National Surveillance System for Healthcare Workers (NaSH). Similar to the NNIS system, NHSN facilities voluntarily report their health care-associated infection (HAI) surveillance data for aggregation into a single national database for the following purposes:

� To collect data from a sample of health care facilities in the United States to permit valid estimation of the magnitude of adverse events among patients and health care personnel. � To collect data from a sample of health care facilities in the United States to permit valid estimation of the adherence to practices known to be associated with prevention of these adverse events. � To analyze and report collected data to permit recognition of

Special Report: Dialysis Surveillance Report: National Healthcare Safety Network (NHSN)—Data Summary for 2006

Thirty‐two outpatient hemodialysis providers in the United States voluntarily reported 3699 adverse events to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) during 2006. These providers were previously enrolled in the Dialysis Surveillance Network. The pooled mean rates of hospitalization among patients with arteriovenous fistulas, grafts, permanent and temporary central venous catheters were 7.7, 9.2, 15.7, and 34.7 per 100 patient‐months, respectively. For bloodstream infection the pooled mean rates were 0.5, 0.9, 4.2, and 27.1 per 100 patient‐months in these groups. Among the 599 isolates reported, 461 (77%) represented access‐associated blood stream infections in patients with central lines, and 138 (23%) were in patients with fistulas or grafts. The microorganisms most frequently identified were common skin contaminants (e.g., coagulase‐negative staphylococci). In 2007, enrollment in NHSN opened to all providers of outpatient hemodialysis.

Making use of electronic data: The National Healthcare Safety Network eSurveillance Initiative

Efforts are underway at the Centers for Disease Control and Prevention to foster greater use of electronic data stored in health care application databases for surveillance of health care-associated infections and antimicrobial use and resistance. These efforts, referred to as the National Healthcare Safety Network (NHSN) eSurveillance Initiative, focus on standards-based solutions for conveying health care data and validation processes to confirm that the data received at the Centers for Disease Control and Prevention accurately reflect the data transmitted by health care facilities. Standard vehicles for data transmission, specifically Health Level Seven standards for electronic messages and structured documents, and standard vocabularies for representing microorganisms and other information needed for surveillance, are central features of the eSurveillance Initiative. Progress to date in this initiative is reviewed, and future project plans are outlined. Enhanced interoperability between health care and public health information systems is achievable for surveillance purposes, but major challenges must be overcome to realize the full benefits sought by the eSurveillance Initiative.

Vital Signs: Preventing Antibiotic-Resistant Infections in Hospitals - United States, 2014.

Healthcare‐associated antibiotic‐resistant (AR) infections increase patient morbidity and mortality and might be impossible to successfully treat with any antibiotic. CDC assessed healthcare‐associated infections (HAI), including Clostridium difficile infections (CDI), and the role of six AR bacteria of highest concern nationwide in several types of healthcare facilities.
