People with diabetes are encouraged to receive diabetes self‐management education and support (DSMES) appropriately. However, in Japan, the implementation rates of DSMES are not known. DSMES implementation rates were calculated using the National Database of claims data, which included nearly all insurance‐covered medical procedures. The study enrolled participants who received regular antidiabetic medications between April 2017 and March 2018. The implementation rates of DSMES‐related care were calculated by characteristics, visiting medical facilities and prefectures. In 4,465,513 participants receiving antidiabetic medications (men, 57.8%; insulin use, 14.1%), nutrition guidance (5.6%) was the most frequently provided care type. Insulin users and participants visiting Japan Diabetes Society‐certified and large medical institutions had higher implementation rates of nutrition guidance. DSMES‐related care might not be provided adequately for Japanese people with diabetes. Further studies are needed to develop an optimal diabetes care system.

使用国家数据库对日本糖尿病患者进行糖尿病自我管理教育和支持的实施率

鼓励糖尿病患者适当接受糖尿病自我管理教育和支持（DSMES）。然而，在日本，DSMES 的实施率尚不清楚。 DSMES 实施率是使用国家索赔数据数据库计算的，其中包括几乎所有保险承保的医疗程序。该研究纳入了 2017 年 4 月至 2018 年 3 月期间定期接受抗糖尿病药物治疗的参与者。DSMES 相关护理的实施率是根据特征、访问医疗机构和都道府县来计算的。在 4,465,513 名接受抗糖尿病药物治疗的参与者中（男性，57.8%；使用胰岛素，14.1%），营养指导（5.6%）是最常提供的护理类型。胰岛素使用者和访问日本糖尿病协会认证的大型医疗机构的参与者的营养指导执行率较高。可能无法为日本糖尿病患者提供充分的 DSMES 相关护理。需要进一步研究来开发最佳的糖尿病护理系统。
