Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) infections remain prevalent and are associated with significant morbidity and mortality. The aim of the present study was to investigate the epidemiology of MRSA infections and antibiotic susceptibility in Qatif, Saudi Arabia. Methodology: All patients who had positive culture for S. aureus from January 1, 2006 through December 31, 2015 were enrolled and analyzed in WHONET, a free database software developed by the World Health Organization (WHO). Patients' data were collected from electronic medical records and traditional chart reviews to determine whether MRSA acquisition was likely to have been in the community or in the healthcare facility. Susceptibility results for community-associated (CA)-MRSA were compared with isolates from healthcare setting. Results: A total of 3395 patients with S. aureus infections were analyzed, with an overall annual MRSA incidence of 25 cases per 100,000 patients (27% of total S. aureus isolates). While the majority (64%) of MRSA infections occurred in healthcare setting, CA-MRSA isolation increased steadily from 23% in 2006 to 60% in 2015, exceeding rate of isolation of healthcare-associated (HA)-MRSA. Skin and soft tissue, the lung and blood stream were the most common sites of infection, with 20% to 35% of MRSA infections occurring in pediatric patients. In the inpatient setting, the majority of infections due to MRSA were in surgical wards and critical care units. Compared with CA-MRSA, HA-MRSA isolates turned out to be more frequently resistant against ciprofloxacin, clindamycin, erythromycin, tetracycline, and trimethoprim/sulfamethoxazole. Conclusions: Staphylococcus aureus continues to cause multiple site infections with a relatively stable methicillin-resistance rate, but the isolation of MRSA from the community is increasing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
