This research is to study the Medical Consultation Service Room (MCSR) for internal medicine outpatients originally founded at the department of metabolism to serve patients of diabetes. In order to study the effect of service, we made an evaluation based on the quantity of health education service, patients satisfaction, and the level of cognition toward diseases. We have obtained the following findings:1. The number of people receiving such services is quite few because of the limitation of service.2. Patients' satisfaction level to the place of health education and the teaching materials is pretty low.3. The level of cognition toward diseases is upgraded after the patients receive health education. Under this circumstance, the open style Medical Consultation Service Counter (MCSC) for internal medicine outpatients was established in hope to extend the service to cover the patients who suffer diseases of internal medcine other than diabetes and need transfer medical. After comparing MCSR and MCSC it reveals that:1. The average number of people receiving health education per working day at MCSC is 15 persons, and the working hours for health education is 3 hours & 19 minutes. As compared with MCSR for 6 persons receiving health education per working day and working hour for health education for 1 hour & 39 minutes, the effect of service is increas- ing obviously for a rate of 50%.2. The level of patient's satisfaction to MCSC reaches 92.5% as compared 81.53% to MCSR.3. The level of cognition toward diabetes, hypertension, and high blood fat is upgrade from 53.78%, 69%, and 61. 22% to 82.02%, 87.20%, and 83.87% respectively after the patients receive health education. Therefore, the effort to expand the previous MCSR to MCSC has achieved success and there is still room for further expansion in the future.
