Abstract:
The operation theatre (OT) complex is a costly component of a hospital budget expenditure. This area of
hospital activity requires maximum utilization to ensure optimum cost-benefit ratio. Two tertiary care centers
in the Colombo district, Sri Jayewardenepura General Hospital (SJGH), the only semi-government tertiary
care center in Sri Lanka, and Colombo South Teaching Hospital (CSTH) providing similar service delivery
to government hospitals were studied to compare utilization patterns. The results showed no significant
statistical difference in average per-bed utilization of SJGH and CSTH (P=0.499). The average per-bed
utilization rate at CSTH was 23.26%, and SJGH was 25.66%. There was a significant statistical difference
in the average per-bed capacity utilization of operating theaters at CSTH and SJGH. The average per bed
capacity utilization time per day was significantly higher at SJGH (P=0.040). The average per-bed capacity
utilization rate at CSTH was 11.63% and 15.2% at SJGH. According to the Consultants' perception of the
importance of factors affecting utilization, less significance is given to time management and related
administrative functions even though they have the highest correlation to utilization factors. Utilization
observed at both hospitals was lower than the global benchmark between 70% and 80%. The study identified
the importance of factors affecting utilization towards human resource availability, motivation, training
needs and equipment, and resource availability. Surgeons have given less priority to time management and
related administrative functions though the literature suggests time management and relative
administratively modifiable factors as the most critical factors. (Gupta, 2011). Therefore, it is recommended
to address the factors such as “cancellation of planned surgeries”, “accurate prediction of procedure times
in scheduling theatre lists”, “convenient theater time schedules with other clinical work”, “patient turn over
time”, and “patient transport time from wards” as they can result in overall improvement in operating
facility utilization.
