Investigating the Mortality Rate of Nosocomial Infections in Patients Admitted to the Intensive Care unit of Imam Khomeini Hospital, Sari

Background and purpose: Nosocomial infections, especially in the intensive care unit (ICU), are critical medical problems worldwide, increasing the length of hospital stay, treatment costs, and mortality. The present study aimed to assess the prevalence of mortality caused by hospital infections in patients admitted to the ICU of Imam Khomeini Hospital, Sari. Materials and methods: The cross-sectional descriptive study was conducted on 289 patients admitted to the ICU of Imam Khomeini Hospital, Sari, from 2019-2020. Culture reports (positive/negative), detected microorganisms, antibiotic sensitivity, and cases of mortality were recorded and evaluated in the checklist. Results: Among 289 patients, 112 cases were female, and 177 subjects were male. The mean age of the deceased was 63.10±14.11 years. According to the data, 86% of patients recovered and 14% died. The most common cause of nosocomial infection was Enterobacter (17.3%), and the most common nosocomial infection was pneumonia (45.3%). The majority of patients who died had taken ceftriaxone. Conclusion: Identification of factors related to increased mortality in patients with nosocomial infections can have a significant function in the management and control of hospital infections. In the present study, multiple drug resistance in pathogens was high. The highest mortality rate was related to Stenotrophomonas maltophilia infection.
