Nosocomial infection rates following cardiothoracic surgery in Iran. of the International Society for Infectious Diseases

摘要

The use of standardized definitions for nosocomial infections allows meaningful comparison of surveillance data between hospitals, and between countries. We used the definitions and methodologies of the CDC's National Nosocomial Infection Surveillance System (NNIS) to compare device utilization rates and infection rates on the cardiothoracic intensive care units (ICU) at two university hospitals in Shiraz, Iran, to the rates generated by NNIS.Three major device-associated hospital-acquired infections were selected for analysis: urinary tract infection (UTI), ventilator-associated pneumonia (VAP), and catheter-associated bloodstream infection (BSI). Data from 478 patients undergoing cardiac surgery and admitted to the ICU during the period 1 March 2000 to 31 August 2000 were prospectively collected and analyzed. A total of 4.1 device-associated infections per 1000 patient-days were documented; individual infection rates and device utilization rates are shown in Tables 1 and 2.
