Managing virtual appointments in chronic care

Abstract

Virtual appointments between patients and healthcare providers can offer a cost-effective alternative to traditional office appointments for managing chronic conditions. Virtual appointments increase contact with the physician by either substituting or complementing office appointments, leading to improved health outcomes. The true value of virtual appointments cannot be realized until they are truly integrated with the office appointment systems. In this study, we introduce a capacity allocation model to study the use of virtual appointments in a chronic care setting. Specifically, we develop a finite horizon stochastic dynamic program to determine which patients to schedule for office and virtual appointments that maximizes aggregate health benefits across a cohort of patients. Optimal policy characterization for this problem is challenging. We find that, under certain conditions, a myopic heuristic, where the sickest patients are scheduled for office appointments and the next sickest patients are scheduled for virtual appointments, is optimal. We show that the myopic heuristic performs well even in more general settings. Our findings further show that virtual appointments serve a dual purpose: they may reduce the number of office appointments and may trigger follow-up office appointments.
