Impact of Education and Process Surveillance on Device-Associated Health Care-Associated Infection Rates in a Turkish ICU: Findings of the International Nosocomial Infection Control Consortium (INICC)

Abstract

Objective: The aim of this study was to analyze the impact of process and outcome surveillance on rates of device-associated health care-associated infections (DA-HAI) in an intensive care unit (ICU) in Turkey over a four-year period. Material and Methods: An open label, prospective cohort, active DA-HAI surveillance study was conducted on 685 patients admitted to the ICU of a university hospital in Turkey from January 2004 to December 2007, implementing the methodology developed by the International Nosocomial Infection Control Consortium. DA-HAI rates were recorded according to Centers for Disease Control and Prevention (CDC), National Healthcare Safety Network (NHSN) definitions. We analyzed the rates of DA-HAI, mechanical ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLA-BSI), and catheter-associated urinary tract infection (CAUTI), as well as microorganism profile, extra length of stay, and hand hygiene compliance. Pooled DA-HAI rates were calculated and compared by year. Results: The DA-HAI rate per 100 patients declined as follows: for 2004, the DA-HAI rate was 58.4%; for 2005, it was 38.9%; for 2006, it was 34.8%; and for 2007, it was 10.9%. The DA-HAI rate per 1,000 bed-days also declined: for 2004, it was 42.8, and for 2007 it was 10.7. The rates decreased from 25.8 to 13.4 for VAP; from 29.9 to 25.0 for CLA-BSI; and from 9.2 to 6.2 for CAUTI cases per 1,000 device-days during the study period. Conclusion: Process and outcome surveillance of DA-HAI significantly reduced DA-HAI.
