Kampo medicine has been incorporated into Japan's medical curriculum nationwide. However, it has not been adopted into its postgraduate medical education. The present study assessed Kampo medicine educational needs for residents in Japanese postgraduate training programs. A questionnaire-based survey was conducted in residents at Japanese Red Cross Ishinomaki Hospital, regarding their experience in prescribing Kampo formulae and the Kampo medicine curriculum they expect in their postgraduate education. Twenty-one residents completed the questionnaires. Seventy-five percent of junior and all senior residents had used Kampo medications. They were mostly provided with on-the-job instruction by attending doctors, senior residents, and fellows during their residency rotations. All residents needed Kampo medicine education opportunities. They expected guidance with respect to the basics of Kampo medicine, and the treatment of common diseases with Kampo formulae. The results of our study demonstrates that residents believe Kampo medicine education should be provided in postgraduate training programs.
