We require our students in the 4th grade to take an on-site pediatric outpatient clinic course at the Teikyo University Hospital as part of a 4-week on-site training program.  This year, 64 trainees divided into groups of 3 or 4 students took the course between June and August.  In the morning, trainees were asked to conduct clinical interviews with 287 patients’ guardians in the presence of trainers.  This was followed by the observation of consultation and treatment services provided to patients.  In the afternoon, students reported the findings obtained in medical interviews, participated in group discussions, and received supplementary lectures from trainers.  After completing the course, students were asked to fill in a questionnaire.  When asked whether they were satisfied with the course, 62.5% and 37.5% of students said “very satisfied” and “satisfied,” respectively, while 64.1%, 29.7%, and 6.2% of students said the observation of consultation and treatment services was “very good,” “good,” and “cannot say which,” respectively.  About the medical interviews, 64.1% and 34.4% said that it is “very good” and “good” to conduct them, while 1.5% said “cannot say which.”  All students said they could determine the problems faced by guardians regarding drugs in the medical interview.  The on-site pediatric outpatient care course was found to be “very useful” and “useful” by 62.5% and 35.9% of patients, respectively, while 1.6% said “cannot say which.”  In conclusion, most students were greatly satisfied with the medical interview with guardians using a questionnaire and said that it made it possible for them to closely communicate with guardians.  This result was thought to be attributable to the use of the techniques of the medical interview OSCE which the students learned prior to conducing medical interviews with guardians.
