Present study was conducted to determine the prevalence of nosocomial pathogen methicillin resistant Staphylococcus aureus in hospital environment samples (surface swabs and air, n=188) and health care workers (nose and hand, n=162) of hospitals located in Kathmandu valley. The samples were studied following the standard protocols. Of the 61 S. aureus, 20.9% and 14.3% were isolated from health personnel and hospital environment respectively. Of 20.9% S. aureus in hospital environment, 6.6% were isolated from OPD and 17.9% from wards. Similarly, in HCWs 28.3% and 13.5% were hand and nasal carrier respectively. In total, 45.9% were MRSA. Among MRSA isolates, 50% were from HCWs whereas, 40.7% from hospital environment. The most effective antibiotic for all isolates was vancomycin with 100% efficacy. The isolates had relatively high rate of resistance to cefixime (44.0%), followed by co-trimoxazole (28.0%), erythromycin (23.0%), gentamicin (18.0%), tetracycline (16.0%) and ofloxacin (8.0%). Since MRSA prevalence was not reduced, so indicates regular surveillance of nosocomial infection, hand hygiene improvement strategies and monitoring of antimicrobial susceptibility pattern.
