Objective: We conducted workshops across Japan to promote the dissemination of the Clinical Practice Guidelines for the Management of Chronic Pain developed by the Ministry of Health, Labour and Welfare's policy research team and evaluated their effectiveness. Methods: The workshops were held in a face-to-face format and consisted of two parts; lectures and group discussions focusing on case studies. A questionnaire was administered before and after the workshops to assess their impact. Results: Post-workshop assessments showed a significant increase in knowledge acquisition and regional collaboration scores across all evaluated items. Discussion: In addition to knowledge acquisition through lectures, group discussions facilitated a deeper understanding among different healthcare professions, suggesting a potential enhancement of regional collaboration. Conclusion: The continued implementation of workshops based on the Clinical Practice Guidelines for the Management of Chronic Pain may contribute to the standardization of chronic pain care.
