Designing extended overall equipment effectiveness: application in healthcare operations
Résumé
Hospitals are forced to develop performance assessment tools, and mainly in areas with high resource consumption and high added value, such as surgical units or operating rooms. Based on methods inspired by lean management in the industry, this paper explores an extended Overall Equipment Effectiveness (E-OEE) approach to an entire process involving material and human resources. This research is based on data on the medical activities of Operating Rooms (OR) in 10 hospitals, as well as the opinions of relevant personnel (physicians, service agents, executives) and analyses of the various existing processes. Additional data were provided in 2015 by four hospitals. In order to solve the performance of processes involving both human resources and critical material resources, we built an indicator based on the measurement of effective valuable time of work executed by the operators, coupled with the measurement of machine performance with a classic OEE model. The extended OEE (E-OEE) is a new indicator to evaluate operating facilities and – possibly – all other activities where high HR involvement is a key factor of performance. E-OEE can complete the traditional Overall Effectiveness indicators taking both HR performance and Equipment performance into account.
