Development of a method for assessing operating room management based on diagnosis procedure combination E- and F-file data

Introduction Due to rising health costs, hospitals are making efforts to assess and improve management efficiency. However, at present, Japanese hospitals rely on individual assessment methods. Due to the lack of a common method of assessment based on standardized data available from all hospitals meaningful comparisons cannot be conducted. The objectives of this study were to develop a method of assessing OR management based on standardized administrative data, and to apply this method in assessing and comparing OR efficiencies in a multi-institutional setting.
