| Research Abstract |
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.
