RESUMO
PURPOSE: Despite of the development of recent medical technology, bloodstream infection (BSI) still has significant influences on mortality and morbidity of patients admitted to the ICU. The BSI has the second most frequent site. Especially BSI in ICU have higher infection rate than general ward. This study was investigated the incidence rate of the nosocomial BSI, risk factors and bacterial pathogens of BSI in ICU for a general hospital. METHODS: This study was carried out for those 443 patients in ICU of general hospital during the period from March 2002 to February 2003. The definition for BSI was based on that of CDC. Data was collected by questionnaire, medical record review. The statistical SPSS(ver. 10.0) was used to analyze data that included chi-square, t-test and logistic regression. RESULTS: In the incidence rates of the BSI were 76.7 in 1,000 per patients, 7.0 in per 1,000 patients days and 32.1 in per 1,000 patients with central lines, 3.2 in per 1,000 cental line days. In the incidence rates of the BSI by type of ICU showed MICU 10.1, SICU 2.9 in per 1,000 patients days. The significant risk factors were identified as type of ICU(OR=5.119, p=0.001), length of stay(OR=1.039, p=0.001). The causal microbes of the BSI were CNS 35.5%, MRSA 23.6%. The bacterial pathogens of central catheter-related BSI were CNS 50%, MRSA 50%. CONCLUSION: The occurrence of ICU-acquired infection was significantly related to the increase in morbidity and mortality. Ongoing targeted surveillance and infection control strategies is necessary to control this problem.
