病例分型是医院以病例为质量单元进行医疗质量评价的基础。在病例分型基础上进行病种病例组合是建立质量、费用标准体系的关键部分。国内外研究病例组合(ＣａｓｅＭｉｘ)的模型较多,本质上都是为了方便医疗质量或医疗费用管理,但研究背景、应用目的、适用范围各有不同。我们介 Case classification is the basis for hospitals to evaluate the quality of medical care using case quality units. The combination of disease cases on the basis of case classification is a key part of establishing a quality and cost standard system. There are many models of CaseMix at home and abroad, which are essentially for the purpose of facilitating the management of medical quality or medical expenses, but the research background, application purpose, and application scope are all different. We are introduced
