CDC definitions of nosocomial surgical site infections, 1992: a modification of CDC definitions of surgical wound infections.
The definition of surgical wound infection was slightly modified and the name was changed to surgical site infection (SSI), which should be used by hospitals wishing to compare their SSI data with NNIS System data. Expand
Surgical wound infection rates by wound class, operative procedure, and patient risk index. National Nosocomial Infections Surveillance System.
A risk index was developed to predict a surgical patient's risk of acquiring an SWI and is a significantly better predictor of SWI risk than the traditional wound classification system and performs well across a broad range of operative procedures. Expand
An overview of nosocomial infections, including the role of the microbiology laboratory
An estimated 2 million patients develop nosocomial infections in the United States annually and the growing number of antimicrobial agent-resistant organisms is troublesome, particularly vancomycin-resistant CoNS and Enterococcus spp. Expand
The efficacy of infection surveillance and control programs in preventing nosocomial infections in US hospitals.
It is found that the establishment of intensive infection surveillance and control programs was strongly associated with reductions in rates of nosocomial urinary tract infection, surgical wound infection, pneumonia, and bacteremia between 1970 and 1975-1976, after controlling for other characteristics of the hospitals and their patients.

National nosocomial infections surveillance system (NNIS): description of surveillance methods.
The National Nosocomial Infections Surveillance System (NNIS) is an ongoing collaborative surveillance system sponsored by the Centers for Disease Control (CDC) to obtain national data on nosocomial infections to develop and evaluate strategies to prevent and control nosocomials infections. Expand
Nosocomial infection rates in adult and pediatric intensive care units in the United States. National Nosocomial Infections Surveillance System.
Comparison of intrahospital and interhospital comparison of ICU infection rates may best be made by comparing ICU-type specific, device-associated infection rates, as well as comparing hospital units with outlier infection rates or device utilization. Expand
The nationwide nosocomial infection rate. A new need for vital statistics.
If adjustments are made for the accuracy of the diagnostic method, the increasing nationwide secular trend, and the number of nosocomial infections in nursing homes, however, as many as 4 million nosocomIAL infections per year may now be occurring. Expand
Identifying patients at high risk of surgical wound infection. A simple multivariate index of patient susceptibility and wound contamination.
The authors used information collected on 58,498 patients undergoing operations in 1970 to develop a simple multivariate risk index and found that a subgroup, consisting of half the surgical patients, can be identified in whom 90% of the surgical wound infections will develop. Expand
CDC definitions for nosocomial infections, 1988.
The Centers for Disease Control (CDC) has developed a new set of definitions for surveillance of nosocomial infections. The new definitions combine specific clinical findings with results ofExpand
Secular trends in nosocomial primary bloodstream infections in the United States, 1980-1989. National Nosocomial Infections Surveillance System.
The emergence over the last decade of coagulase-negative staphylococci as one of the most frequently occurring pathogens in BSI is documents. Expand
