Development of methods for risk adjustment and quality evaluation of health care by administrative data

DPC数据是日本急性护理医院的管理数据，对医疗质量分析和医院功能评估有潜在的帮助。本研究目的在探讨以DPC行政资料进行医疗品质分析之方法。我们通过DPC过程数据调整病例组合，成功评估了包括急性冠状动脉介入治疗后的住院死亡率和髋部骨折手术后的住院时间。我们已经表明，DPC数据是非常有价值的医疗保健质量评估和临床流行病学。在日本，建设和维护用于临床研究的全面和代表性DPC数据库是高质量临床研究和循证卫生政策的强制性要求。

DPC data is administrative data of acute care hospitals in Japan potentially useful for the analysis of health care quality and the assessment of hospital functions. The purpose of this study was to develop methodology for health care quality analysis by DPC administrative data. We have shown successful outcome assessment including hospital death rate after acute coronary interventions and the length of hospital stay after hip fracture surgery by case-mix adjustment with DPC process data. We have shown that DPC data is highly valuable for health care quality assessment and clinical epidemiology. The construction and maintenance of comprehensive and representative DPC data base for clinical research use is mandatory for high quality clinical investigations and evidence-based health policy in Japan.
