NOSOCOMIAL INFECTIONS ASSOCIATED WITH DEVICE USAGE IN A TERTIARY CARE HOSPITAL IN NORTHERN INDIA

Abstract

ABSTRACT:

Nosocomial infections are a frequent occurrence in ICUs because of the severity of underlying diseases, the frequency of invasive interventions, and the frequent use of wide-spectrum antibiotics. This prospective study was undertaken with the aim to determine nosocomial infections and to study predisposing risk factors in patients being submitted to an ICU in a tertiary care hospital. Swab samples were collected from patients with endotracheal intubation and central venous catheters. The risk factors for bacterial colonization in the ICU were hospitalization for more than 48hrs, use of multiple antibiotics, preexisting co-morbidities and use of mechanical ventilation. The results of the study delineate the fact that knowledge of resident microbial flora and their sensitivity profile is of utmost importance while making guidelines for treatment strategies in ICU patients.
