The use of case mix to explain hospital costs has been refined in previous research on the cost of hospital-based health care. This study demonstrates the significance of hospital case mix in explaining charges for health care treatment. By assuming that the variables which influence cost should also influence charges, an evaluative function is added to the basic investigative analysis potential of the hospital production process model. The relationship between case mix and charges is found to be weaker than the relationship between case mix and costs. This difference is qualified by methodological variation and possibly explained by cross-subsidization of patient services and lack of adequate controls on charge determination. Further, the relationship between case mix and charges is found to differ between Medicare and Blue Cross patients. This evidence suggests that hospital accounting may not be recovering costs evenly and equitably from clients.
在先前关于医院医疗保健成本的研究中，病例组合用于解释医院成本的方法已得到完善。本研究证明了医院病例组合在解释医疗保健治疗费用方面的重要性。通过假设影响成本的变量也应影响费用，在医院生产过程模型的基本调查分析潜力中增加了一个评估功能。研究发现病例组合与费用之间的关系比病例组合与成本之间的关系更弱。这种差异因方法上的变化而有所不同，可能是由于患者服务的交叉补贴以及对费用确定缺乏充分控制所致。此外，研究发现医疗保险患者和蓝十字患者的病例组合与费用之间的关系存在差异。这一证据表明，医院会计可能没有从客户那里均匀且公平地收回成本。
