Role of incidence of blood and urinary tract infections in the burn patients admitted in Ghotbeddin burn center of Shiraz, 2000-2001

Background and purpose: Though bum wound infections have been extensively studied, but other nosocomial infections in bum patients have received less attention. Invasive diagnostic procedures (vascular and bladder catheterization) make the burn patients more susceptible to different nosocomial infections. The aim of this study was to determine the incidence rates of blood stream and urinary tract infections associated with IV line and urinary catheter in Ghotbeddin burn center and also to compare these rates with those of the National Nosocomial Infections Surveillance System (NNIS) in the U.S.A. Materials and methods: This study was conducted for 11 months, from 2151 December 2000 to 21st November 200I. All the patients admitted for more than 48 hours without evidence of infection at the time of admission were included in this study. For diagnosis of urinary tract and blood stream infections, the standard definitions of the Center for Diseases Control (CDC) were used. Results : Of 106 eligible patients under study, 91 acquired different nosocomial infections (85.85%). Urinary catheter-associated urinary tract infection (UC-UTI) rate was 30 per 1000 urinary catheter days and IV line associated blood stream infection (IV line-BSI) rate was 17 per 1 000 IV line days. Conclusion: Comparison of incidence rates of UC-UTI and 1V line-BSI in Ghotbeddin hospital and NNIS showed that, rate of infection is more in Ghotbeddin hospital (P<0.001) while device utilization ratio (urinary catheter and central line) was more in the NNIS hospitals (P<0.001). In order to reduce the rate of infection, education, development of standardized guidelines for the use of invasive devices and introduction of a nosocomial infections surveillance system are necessary.
