Epidemiology of microbial infections in the intensive care unit of Rasoul Akram Hospital in Tehran during 2016-2018

Microbial infections are one of the main causes of death in the intensive care unit (ICU) of hospitals. The aim of this study was to investigate the epidemiology of microbial infections in the ICU of Rasoul Akram Hospital in Tehran during the years 2016 -2018.

A retrospective study was conducted on 1150 patients in the ICU of Rasoul Akram Hospital in Tehran between 2016 and 2018. The required information was extracted from the medical records of hospitalized patients and then the data were analyzed.

Out of 1150 patients, 641 (55.7%) were men. The average length of hospitalization of patients with nosocomial infections in the ICU was 18±7.6 days. The most common cause of nosocomia infection was Klebsiella pneumonia. The highest frequency of death of patients was related to Ascentobacter. Also, other findings of the study showed that there was a significant direct relationship between the death and discharge of patients with nosocomial infections with the gender, type of organism, age, and length of hospitalization (p<0.05). The findings of the study also showed that infection was significantly associated with death (39.7%).

The findings of this study showed that the variables of gender, age, type of organism, and duration of hospitalization can be risk factors for the death of patients hospitalized in ICU. Therefore, preventive policies and control of nosocomia infections should be focused on these variables.
