Labelling a hospital admission with a single disease code based on the selection of the patient's principal diagnosis poses problems for clinicians, administrators and epidemiologists. The use of a case-mix grouping classification, Diagnosis Related Groups (DRGs), allows the modification of the principal diagnosis by other factors affecting the length of stay of the patient in hospital. This system requires as its entry point a decision on which diagnosis is the principal one. The definition of principal diagnosis in Australia differs from that used in the United States where DRGs were developed. We describe a study to determine how often the use of the Australian definition leads to the allocation of a different DRG.
基于患者主要诊断的选择，仅用单一疾病代码对住院情况进行标注，给临床医生、管理人员和流行病学家带来了问题。使用病例组合分组分类法，即诊断相关组（DRGs），可以根据影响患者住院时长的其他因素对主要诊断进行修正。该系统要求作为其切入点的是确定哪个诊断是主要诊断。澳大利亚主要诊断的定义与开发DRGs的美国所使用的定义不同。我们描述了一项研究，以确定使用澳大利亚定义导致分配不同DRG的频率。
