Three-Year Evaluation of Nosocomial Infection Rates of the ICU

Evaluating the incidence of nosocomial and invasive device-related infections enables the comparison of the health care associated infection (HAI) between the intensive care units of different hospitals and different units in the same hospital. A retrospective surveillance study was performed to identify nosocomial infections, device-related infections rates, and causal agents from January 2007 through December 2010 in the Anesthesiology Intensive care unit (ICU). HAI were defined according to the CDC (Centers for Disease Control and Prevention) criteria, and invasive device-related infections were defined according to National Nosocomial Infection Surveillance System (NNIS) criteria. During a two-year period, 939 patients were analyzed throughout a total of 7,892 patientdays. The rates of HAI were 53% in 2007, 29.15% in 2008, 28.85% in 2009 while 16.62% in 2010. Most common HAI was blood stream infection. The rate of soft tissue and skin infection was the second most common. Overall, the most common agents were Gram(−) 56.68%, Gram(+) 31.02% and Candida spp 12.3% among patients with nosocomial infections. The incidence of HAI in the ICU of our hospital was high, compared to the Turkish overall rates obtained at the Refik Saydam Center in 2007. When the rates of device-related infections between 2007 and 2008 were compared, they were higher in 2007. The rates of devicerelated infections were diminished in 2008 to below-national mean rates by infection control measures. Since the rate of urinary catheter-related infections are still high, we should exert continuous efforts for infection control. Avaliar a incidência de infecções nosocomiais associadas aos dispositivos invasivos permite comparar as infecções associadas aos cuidados em saúde (IACS) entre as unidades de terapia intensiva (UTI) de diferentes hospitais e unidades do mesmo hospital. De janeiro de 2007 a dezembro de 2010, um estudo de vigilância retrospectivo foi realizado para identificar infecções nosocomiais, taxas de infecções relacionadas a dispositivos e agentes causadores na UTI de anestesiologia. As IACS foram definidas de acordo com os critérios do Centro de Controle e Prevenção de Doenças (CDC) e as infecções relacionadas aos dispositivos invasivos definidas de acordo com os critérios do Sistema Nacional de Vigilância de Infecções Nosocomiais (NNIS). Durante dois anos, 939 pacientes em um universo de 7.892 pacientes/dia foram avaliados. As taxas de IACS foram de 53% em 2007, 29,15% em 20
