Outline of Final Research Achievements

We further developed multi-source, multi-dimensional, longitudinal micro databases of health and long-term care insurance claims and health screening through collaboration with the national government, local governments and hospitals nationwide. We analyzed them under strict information security management system.
Health and social care performances, including quality, cost, efficiency, access and equity, were visualized and analyzed at institutional and regional levels, utilizing advance methods such as machine learning. Innovative risk-adjustment methods were developed for outcome performance measurement. Modeling and simulation technologies were also utilized in the analyses. Resource set up such as centralization and networking were found to be effective on healthcare performance. The causal structures of health and social care performance, resources manpower and others, socioeconomic and demographic factors were explored and analyzed, and various new evidences were produced.
