Abstract

An operating room is a unit that functions as a place for surgical procedures. The operating room provides the most significant contribution to hospital revenues and has the highest maintenance expenses. It is necessary to use the operating room as efficiently as possible. In part of surgical procedures, there is a changeover time when the officer turns off the operating room lights in the previous surgery until the officer turns the lights on in the operating room as a signal that the subsequent surgery will begin. Long changeover time could reduce operating room utilization and hinder hospitals in providing reasonable service satisfaction to patients. This study aims to identify and analyze the factors that cause the significant change in the operating room. Identification and analysis are carried out by considering two factors, namely internal time and delay itself. Internal time is the calculated time while the operating lamp is off. Delay itself is a delay that results in a long pre-operation change over time due to the activity itself. This research used Value Stream Mapping (VSM) to describe the business process, identify the location of wastes in the process, and present the current and future conditions after improvement. Ishikawa diagram is used in this study to help determine the root cause of the activities involved in the delay factor. The result of this research indicates that changeover time is reduced by 37 minutes (43%) for a minor operation and 79 minutes (54%) for a significant operation.
