Occurrence of Nosocomial Infection in Intensive Care Unit of a Public Hospital

Abstract

Introduction: Health care-associated infections stand out in scientific investigations for being related to increased length of stay as well as to morbidity and mortality rates, of hospitalized patients, especially in intensive care units. The study aims to profile the occurrence of invasive device-associated infections in an intensive care unit of a public hospital in Rio de Janeiro. Outline: Descriptive, documentary study with data collected in 2018 through form including patients hospitalized in 2016. For univariate analysis, Kaplan–Meier estimate and Longrank test with value p <0.05% were used. Results: 181 predominantly male patients (53.59%) ≥ 60 years (37.57%). Indwelling urinary catheter was the most used device although the highest percentage of infection was with invasive mechanical ventilation. The nosocomial infection rate was 28.73% predominantly in respiratory tract (56.91%). Implications: There was an association between nosocomial infection and the use of invasive devices investigated in the study, considering that the time of use was the most related factor.
