CONTEXT: A top-down evaluation of the costs of operating rooms (ORs) is not commonly done because it is relevant mostly in a publicly funded system. OBJECTIVE: This study was conducted to determine the costs and utilization of ORs in a public hospital in Trinidad, West Indies, for two one-year periods using a top-down model. DESIGN: Quantitative observational study.Main Outcome Measures: A "cost-block" model suggested for evaluation of intensive care unit costs was adapted to suit ORs. Data were obtained from personal interviews, records, and surveys from the appropriate hospital departments. Adjusted OR utilization times also were recorded for both years. RESULTS: The total annual costs of 4 ORs for the years 2006 and 2009 were approximately US $2.2 and $3.2 million, respectively. Capital expenditure contributed to 70% of the costs, followed by consumables (15%) and medical staff salary (8%). The daily cost of running the ORs was US $6242 in 2006, which rose to $8873 in 2009. The cost of unutilized OR time was approximately US $298,342 in 2006 and was reduced to $198,315 during 2009. CONCLUSION: The adapted cost-block model was useful to evaluate the costs of ORs in a public hospital in Trinidad and can be used from the government's expenditure perspective. Because the cost of running the ORs was high, efficiency must be improved to minimize waste.
