Abstract

The waiting time of patients is an important factor related with service quality of a hospital system. An appointment system of patients is not popular, in special, in a private hospital. An appointment system is expected to diversify patients in time and to reduce patient's waiting time. Three appointment rules are suggested and analyzed to compare the waiting time of appointment and walk-in patients using simulation analysis. The results of two way ANOVA show that the time slot of 30 minutes for allocating appointment patients is better than the time slot of 60 minites in view of patient's waiting time. The results of the appointment level 1 also show that the constant pattern rule and the zigzag pattern rule give shorter waiting time for walk-in patient and for appointment patient, respectively.

환자의 대기시간은 의료시스템의 서비스품질을 결정하는 중요한 요소이다. 개인병원의 경우 아직 환자 예약제가 보편적이지 않다. 예약제는 환자들을 시간적으로 분산시킴으로써 환자의 대기시간을 감소시킬 것으로 기대된다. 본 논문에서는 세 가지 예약규칙을 제안하고 시뮬레이션 기법을 이용하여 예약환자와 비예약환자의 대기시간을 비교분석한다. 시뮬레이션 결과 분석을 통해 예약자 할당 슬롯의 길이가 60분일 때보다 30분일 때 환자의 대기시간이 짧게 나타났음을 보여준다. ANOVA 분석을 통해 예약자 할당수준 1에서 비예약 환자의 경우는 일정패턴 규칙에서 예약 환자의 경우에는 지그재그패턴 규칙에서 평균대기 시간이 짧게 나타나고 있음을 보인다.
