| Outline of Final Research Achievements |
We developed a longitudinal health and long-term care database by the linkage with the Kokuho database (KDB) in Fukuoka prefecture and the original claims data, as the National Health Insurance and the medical care system for the elderly in the latter stage of life are independently operated in Japan, the health insurance data of those beneficiaries are fragmented among those systems.
Furthermore, we evaluated the continuity of care by calculating the Continuity of Care Index (COCI) based on the claims database and its effects on the long-term health outcome and health care and long-term care resource utilization.
We revealed that the diabetic patients whom newly received treatment with COCI less than 0.75 had a lower risk for admission and less healthcare expenditure than those with COCI < 0.75.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、これまでの保険者単独あるいは横断的な分析ではなく、確度の高いDeterministic Linkageによる保険者縦断的なアプローチを用い、特定健診、医療・介護保険レセプトデータを個人単位で連結可能な形で統合した長期間追跡可能なデータベースを構築した点で高い学術的意義と有すると考えられる。また、我が国において、これまで行われていなかったケアの継続性の評価について、実際のレセプトデータを用いて評価し。その長期予後及び医療・介護費に与える影響を評価した点は、十分な社会的意義を有していると考えられる。
