Outline of Final Research Achievements

This investigation examined the presence and characteristics of hospitals where dentists work and the collaboration between medical and dental teams. Indicators described were the proportion of hospitals employing dentists, those providing perioperative oral care, and those with a nutrition support team (NST) that included dentists. Some hospitals had poor medical and dental collaboration, even those with dentists, and no-dentist hospitals had rare medical and dental collaboration. Factors positively associated with hospitals that employed dentists were diagnosis-procedure-combination-hospital types, the Japanese government-established hospitals compared with hospitals established by public organizations.

Academic Significance and Societal Importance of the Research Achievements

本研究から、医科歯科連携加算を算定されるかは病院の特性や二次医療圏で大きく異なることがわかり、是正するためのシステム作りや医科歯科連携加算の啓発などが必要であると考えられた。また、入院中の患者医科歯科連携加算の算定状況が歯科の口腔指標の一つとなる可能性を示唆した。本研究結果を英語論文にまとめて執筆し、査読付き国際誌に受理され、現在公開されている。
