Methicillin-Resistant Staphylococcus aureus: The Magnitude and Risk Factors among Patients Admitted to Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.

Out of 413 collected specimens, 38.7% had coagulase-positive S. aureus of which 35.6% (95% CI: 28.2%-43.0%) were MRSA. Being within the age group of 19-29 years and 30-39 years with AOR = 5.02 and 95% CI: 1.24-20.35 and AOR = 6.65 and 95% CI: 1.78-24.78, respectively, admitting in the hematology ward and the pediatric ward with AOR = 7.80 and 95% CI: 1.82-33.49 and AOR = 10.54 and 95% CI: 1.78-62.42, respectively, and experiencing poor prognosis with AOR = 10.97 and 95% CI: 4.57-26.36 were significantly associated with MRSA infection. Conclusion and Recommendation. The significant magnitude of MRSA was found among patients admitted to this hospital. Therefore, identified risk factors should be considered when executing hospital-acquired infection prevention programs. We also suggest that healthcare providers should consider the identified risk factors while prescribing the antibiotic.
