Abstract
-
Purpose: The purpose of this study is to determine the risk adjusted nosocomial infection (NI) rate and distribution of Nls and their causative pathogens in adult lCU.
Methods
Prospective surveillance was performed at 12 lCU's of 5 acute care hospitals in Seoul and Kyonggi Do during a 3-months period from May to July 2002. The case finding was done by direct reviews of medical charts regularly for all patients by ICPs using CDC definitions.
Results
Total NI rate was 10.18/1,000 patient-days in Medical-surgical ICU (MSICU) and 12.35/1,000 patient-days in Neurosurgucal ICU(NCI). Risk adjusted infection rate was 3.44 in indwelling catheter associated UTI 2.12 in central line associated BSI. 3.51/1,000 device-days in ventilator associated pneumonia in MSICU. There were 3.72, 2.26, 6.06/1,000 device-days in NCU. The infection rate by leu type showed no significant difference. The distribution of Nls were PNEU (28.99%). UTI (28.99%), BSI (18,84%), SSI(4.35%) in MSICU, and UTI(48.0%), PNEU(24.0%), BSI (14.0%), SSI(6.I) in NCU. The most commonly isolated organisms were Candida spp (38.6%), Enterococcus spp. (13.4%) in UTI, Staphylococcus aureus(36.2%), p. aeruginosa(18.8%) in PNEU and Coagulase negative staphylococcus(44.1%). S. aureus (14.7%) in BSL, S. aureus (19.8%) was the most common organism from overall nosocomial infections in the ICU, and 96.3% of S. aureus were MRSA.
Conclusion
Distribution of site-specific nosocomial infection and isolated organisms were similar to the results of KOSNIC (Korea society for nosocomial infection control) surveillance in 1996. However, the total infection rate and a risk adjusted infection rate at MSJCU is lower than 1996's. This decrease is considered to be a result of efforts to prevention and control nosocomial infections.
