To improve hospital quality, the development of authorized clinical instructors is urgently needed. Therefore, we held a workshop to develop clinical instructors. At a monthly meeting of the clinical training committee in June 2014, an agenda for holding a workshop was proposed. At the meeting in July 2014, most committee members said they were reluctant to hold a workshop because of heavy clinical duties. However, the hospital president strongly suggested that a workshop might be a foundation for reforming the stagnated hospital and persuaded committee members to hold a workshop to improve the instructors’ skill in teaching residents. At the September meeting, the workshop schedule was discussed. All members of the taskforce, except the chief coordinator and a lecturer, were selected from hospital physicians, and 3 preparatory meetings and 1 rehearsal were held. With the help of administrative staff, our first workshop for clinical instructors was held at Daido Hospital in February 2014. Our workshop helped create new hopes for improving educational tasks at our teaching hospital and improved the educational skills of participants. We also achieved mutual understanding as a team to accomplish a single goal.
