Nosocomial infections associated to invasive devices in the intensive care units of a national hospital of Lima, Peru

Abstract

In order to describe the incidence of nosocomial infections associated to invasive devices in intensive care units (UCI) of the National Hospital Cayetano Heredia, a retrospective observational study was conducted using the data from the Office of Epidemiology and Environmental Health from 2010 to 2012. A total number of 222 nosocomial infections were reported; the general medicine UCI reported the highest incidence of pneumonia cases associated to a mechanical ventilator in 1000 days of use of the device (28.6); infection of the blood stream associated to central venous catheter (11.9), and infection of the urinary tract associated to a catheter (8,1). The main infectious agents isolated were Pseudomona sp. (32.3%) in the emergency UCI, negative Staphylococcus coagulasa (36%) in the general medicine UCI and Candida sp (69.2%) in the Surgery UCI. The rates of infections associated to invasive devices were high as in other national hospitals with limited resources and infrastructure.
