Epidemiological manifestations and impact of healthcare-associated infections in Libyan national hospitals

BACKGROUND

Healthcare-associated infection is a serious global problem, particularly in developing countries. In North African countries, comprehensive research on the incidence and effects of such infections is rare. This study evaluated the epidemiology and determined the impact of healthcare-associated infections in Libyan national teaching hospitals.

METHODS

A prospective longitudinal study was carried out in Libya's four largest teaching and referral hospitals (Tripoli Medical Center, Tripoli-Central Hospital, Benghazi Medical Center, and Sabha Medical Center) from November 1, 2021, to October 31, 2022. The epidemiological events and the parameters incorporated in this study were based on the data published by the Libyan Centers for Disease Control. The surveillance was carried out on all patients admitted to the wards of medicine, surgery, intensive care, gynecology & obstetrics, and pediatrics in all four hospitals. Trained staff reviewed the medical records and compared the percentages of patients with healthcare-associated infections. Bio-statistical and multivariable logistic regression analyses were carried out to test the variables associated with healthcare-associated infections and the resulting deaths.

RESULTS

A total of 22,170 hospitalized patients in four hospitals were included in the study. Hospital-acquired infection was reported in 3037 patients (13.7%; 95% CI: 12.9-14.4%). The highest incidence was in Benghazi Medical Center (17.9%; 95% CI: 16.9-18.7%), followed by Sabha Medical Center (14.8%; 95% CI:14.9-16.51%). Surgical site infection was the most prevalent (31.3%), followed by ventilator-associated pneumonia (29.3%), urinary tract infection (26.8%), and bloodstream infection (12.6%). Patients with healthcare-associated infections experienced severe morbidity requiring intervention. New antimicrobial regimens were needed for 1836 patients (93%), and 752 patients (34%) required admission to intensive care. Surgical intervention, respiratory support, and inotropes were also needed as a consequence of HAI events.

CONCLUSIONS

The high incidence of healthcare-associated infections in Libyan hospitals should be considered a major problem and a serious burden. This should alert healthcare authorities at the national and hospital levels to the urgent need for preventive and control strategies to combat hospital-acquired infections.
