Exploration and practice of benefit evaluation for medical equipments based on objectives and key results / 中华医院管理杂志

The study aims to improve the level of fine management of medical equipments, give full play to the functions and roles for better patient service, and explore methods for evaluating the benefits of medical equipment that can take into account and reflect the needs of multiple parties. Based on objectives and key results(OKR) methods and concepts, a benefit evaluation system was developed with the goal of giving full play to the functions and roles of medical equipments, with corresponding evaluation indexes and supervision and evaluation mechanisms formulated as well. This index system could take into account the needs and concerns of hospitals, the departments in use, the management authorities and patients at large, while contributing to process supervision and continuous improvement. In the OKR practice of large medical equipments(CT, MR) from 2018 to 2019, they had performed significantly better in inspections, inspection positive coincident rates, clinical service capabilities, maintenance assurance levels, patient satisfaction, scientific research and academics among others. The use of a medical equipment benefit evaluation system based on OKR concepts and methods can provide effective evaluation indicators for the operation and management of medical equipments. In addition, the system can maintain internal improvement momentum leveraging process supervision and continuous improvement methods, in order to assure the elevation of fine management level of medical equipments of modern hospitals, thus offering better medical services for patients at large.
