the huge volume of resources. One specific unit that consumed the largest volume of resources in hospital is operating theatre. Previous researches in different countries had studied about operating theatre performance, but in Indonesia less research has been conducted. Operating theatre performance is measured by utilization rate, however the way utilization measured in practice is different with the general terminology. We conduct research in one referral hospital. It was declared that although the utilization of operating theatre is not high, many patients wait for the services. Therefore, the objectives of this research are to validate the low utilization rate and to identify causes of unutilized capacity of operating theatre. This research applies statistical description method and Monte Carlo simulation for four operating theatres. Statistical description is used to analyze the utilization with general terminology, and the simulation is run to identify what factors that cause unutilized <br /> <br /> <br /> <br /> <br /> capacity. Three scenarios are used in the simulation. First scenario is simulation with no cancellation occurs, the second is simulation with cancellation, and the third scenario is simulation for determining unutilized capacity due to waiting and idle time in operating theatre. <br /> <br /> <br /> <br /> <br /> This study has successfully revealed factors causing unutilized capacity of operating theatre i.e. number of cancellation, waiting for facilities, and idle capacity. Our study shows that 1% of cancellation rate will reduce utilization about 1%. This study also indicates that unutilized capacity due to waiting for facilities and idle time in these operating theatres is fairly high. It had confirmed that operating theatres in the hospital are in low utilization and need for improvement. Determining utilization rate with Monte Carlo simulation provides more information to hospital manager for decision making process.
