Abstract

Introduction: There are various infection diseases that have a significant impact on the health of the people. The healthcare associated infections are important cause of the patient morbidity and mortality. Research shows that the microbiological contamination of air and environment in the Operation Theaters (OTs) are one of the major risk factors of Surgical Site Infection (SSI). More than 10% patients admitted to acute care hospitals in the developed nations and 25% patients in developing nations got the infection, which was not presented at the time of admission. Annually, more than 1.3% patients were reported with SSI, and it caused 15000 deaths.
Aim: The study aims to conduct a retrospective analysis of microbiological surveillance of operation theatres
Materials and Methods: This retrospective study analyzes the microbiological surveillance data from OTs over a period of 5 years from April 2017 up to March 2022 and was conducted at a tertiary care hospital, Odisha, India. Prior approval for the study was taken from the institute, and Ethical committee has provided the guidelines for maintaining the standard approach. For collecting the sample, two groups were defined that involve the swabbing surface and settle plate method. Moreover, a total of 4200 surface swab samples were taken from the 5 OTs of the hospital during the study. Out of these, 900 samples per OT were collected from General Surgery, Urology, Orthopedics and Ear, Nose, Throat (ENT) OTs whereas 600 samples were from Ophthalmology OT.
Results: Staphylococcus aureus count was 7 (3.2%) and Enterococcus spp. was 6 (2.7%). Moreover, the bacterial CFU/m was analyzed for identifying the level of infection through air. As per the outcome of the analysis, the count of air was ranged from 28-134 as the general is having highest count 137 and Ophthalmology was having least in OT.
Conclusion: The study has shown that surgical site infection is a serious problem for the postoperative patients and staff members as it causes chronic illness that could lead to uncertain death. The microbiological quality of the air and surface of the OTs plays a critical role in such illness and issues to patients and staff members. However, the hospitals tries to maintain the good level of hygiene and low bacterial contamination rates on surface swabbing and CFU count per m of air within permissible limits.
