Abstract: Patient dissatisfaction has long been a recognised problem in current outpatient healthcare delivery systems especially with patient wait time. Many solutions have tried to improve the service quality from the view points of cost reduction and increasing utilisation of medical staff. However, the uncertainty of physician treatment time has been one of the primary concerns for effective scheduling. This paper demonstrates an analytical concept on improving quality of service for a clinic from the aspects of reducing costs and waiting by reclassifying patient visit groups in order to reduce the variability of physician service uncertainty. A case study from an orthopaedic surgery clinic is presented to illustrate the classification method by using a decision tree technique and how the redesign of scheduling better manages the variability of treatment times, helps alleviate the wait time for both patients and physicians, reduce overall costs of waiting and overtime, and consequently, improve the overall service quality.
