Microbial contamination of operation theaters (OTs) is a major cause of nosocomial infections (NIs). Nosocomial infection is a main hassle in any healthcare facility. UTI, Surgical site infection, pneumonia and blood stream infections are the big four healthcare associated infections. Purpose of the study is to find out prevalence rate of microorganisms in Operation Theatre to find out the frequency of contamination from various sites in Operation Theatre.
The study was carried out at the Department of Microbiology, General Hospital, Mehsana for a period of five years (from January 2012 to December 2016). Total of 5600 swab samples were collected from various Operation Theatres over a period of five years. Out of total 5600 swab samples were collected 503 (8.98%) were positive for growth. Among GNB isolates from swab sampling Pseudomonas 84 (42.64%) is the most frequently isolated organism and among GPC CONS 49(81.66%) is most frequently isolated organism. Gynec OT has highest rate of GNB 16(12.70%) isolation. GPC isolation rate 20(2.30%) is highest in Surgical OT. While GPB isolation rate 46(5.35%) is highest in Family planning OT. From organisms isolated from various surfaces by swab sampling it is evident that most organisms were isolated from Laprotomy Instrument 37(82.22%).
