Impact of a new medical network system on the efficiency of treatment for eating disorders in Japan: A retrospective observational study

Abstract

Background: In Japan, patients generally have free access to any hospital or clinic. This could lead to reduced efficiency in the treatment for eating disorders (EDs) because there are only a limited number of doctors who can treat ED patients. The objectives of this study were to examine the efficiency of a new trial system for consultation and appointments, a medical community network (MCN), in outpatient treatment for EDs. MCN schedules appointments for the first visit only by referral from another medical institution, not by patients themselves. Methods: We analyzed the data of 342 outpatients (mean age=28.9±9.9years; 328 female and 14 male) who visited the ED clinic at the University of Tokyo Hospital for the first time between January 2009 and July 2012 to investigate possible differences in treatment efficacy between the new (MCN+) system and the conventional (MCN-) system, which accepts reservations directly from patients. Results: The no-show rate for MCN+ patients (0.8%) was significantly lower than that for the MCN- group (17.8%) (p<0.001). MCN+ patients had a significantly shorter waiting period (8.4days) for the first visit compared to MCN- patients (35.5days, p<0.001). In addition, the MCN+ group had a much higher rate of successive visits to the clinic (p<0.05). Conclusion: This new consultation system using a medical community network provided more efficient treatment for ED than did the appointment system in which the patients made their appointments by themselves.
