In the first of two articles on the subject, the authors explain what Case Mix Groups (CMGs) and Resource Intensity Weights (RIWs) are and how they are used. The former categorize hospital patients into groups. The latter are ratios showing the relative use of hospital resources for a typical case (successful course of treatment in an acute care hospital and discharge when the patient no longer requires the hospital's services) and atypical cases (death, transfer, sign-out and substantially longer than average stay) in each CMG. As such, CMGs and RIWs define the relation between the medical and financial dimensions of hospital cases for use in planning and management. Ontario and Alberta are the first provinces to use them to adjust hospital funding. CMGs are limited by the number of diagnoses contained in each category, and RIWs are limited by the use of New York cost data due to the lack of Canadian data.
在关于该主题的两篇文章的第一篇中，作者解释了病例组合分组（CMG）和资源强度权重（RIW）是什么以及它们是如何使用的。前者将医院患者分类成组。后者是一些比率，显示了每个病例组合分组中典型病例（急性护理医院成功的治疗过程以及患者不再需要医院服务时出院）和非典型病例（死亡、转院、签出以及住院时间远长于平均水平）对医院资源的相对使用情况。因此，病例组合分组和资源强度权重定义了医院病例在医疗和财务维度之间的关系，以供规划和管理使用。安大略省和艾伯塔省是率先使用它们来调整医院资金的省份。病例组合分组受到每个类别中所含诊断数量的限制，而资源强度权重由于缺乏加拿大数据而受到使用纽约成本数据的限制。
