Small groups of 5th-year medical students performed a survey of hospital patient services in hygiene and public health, with an emphasis on patient waiting time. The purpose of this course was to give medical students the opportunity to experience the waiting time endured by patients and to obtain some understanding of the quality of hospital services from the patient's point of view. The survey was performed as follows. Groups of five students accompanied new patients in the department of internal medicine from registration until payment. The students recorded waiting time and examination time. During the waiting time, the students asked the patient questions to evaluate service. Patients were cooperative in giving responses during the survey. After the survey, the students summary proposed how to improve services for patients. By accompanying and talking with patients, the medical students were able to understand hospital systems from the patient's point of view. This course should prove useful for these students future careers in medicine.
