Most efforts to modify the diagnosis-related group (DRG) case classification system focus on variables related to medical management. In this study, we investigated the separate but related natures of medicine and nursing by examining 1,288 adult medical and surgical patients in an urban teaching hospital. The complexity of medical treatment was measured by use of the DRG relative cost weight. The nursing indicator was derived from a set of nursing diagnoses. We found that the DRG cost weight is a poor predictor of nursing dependency and that the nursing dependence index added significantly to the DRG weight in explaining length of stay.
大多数改进诊断相关分组（DRG）病例分类系统的努力都集中在与医疗管理相关的变量上。在本研究中，我们通过对一家城市教学医院的1288名成年内科和外科患者进行调查，研究了医疗和护理各自不同但又相互关联的性质。医疗治疗的复杂性通过DRG相对成本权重来衡量。护理指标源自一组护理诊断。我们发现，DRG成本权重并不能很好地预测护理依赖程度，而且在解释住院时间方面，护理依赖指数在DRG权重的基础上有显著补充作用。
