Introduction: This report details surgical site infections (SSIs) due to Methicillin resistant staphylococcus aureus. SSIs was observed among patients undergoing Total abdominal hysterectomy procedures performed in between 15 days of time frame.
Aim: The investigation aimed to identify the source of the SSI, contributing factors, and implement control measures to prevent further infections.
Materials and Methods: A case was defined as any patient who underwent the specified surgery during the designated timeframe and developed an SSI within 30 days of the procedure, as defined by the Centres for Disease Control and Prevention criteria. Medical records were reviewed to identify patients meeting the case definition. Demographic information, surgical details, laboratory results, and infection control practices were collected for each case. Swab samples were collected from the operating room environment, including surgical equipment, surfaces, and air. Clinical and environmental samples were analysed in the hospital laboratory to identify the causative organisms.
Results: A total of 5 patients were identified as meeting the case definition for SSI in between 15 days. Microbiologically MRSA isolated from all five patients. Nasal and hand swabs collected from healthcare workers of obstetrics & gynaecology unit and surgical service department of OT to detect MRSA. Among the 25 health care workers, 14 (56%) were MRSA carrier (6 hand carrier (24%) and 8 (32%) nasal carrier).
Conclusion: The investigation findings were used to propose specific control measures to prevent future outbreaks and improve patient safety.
