ABSTRACT:
Primary
care, the backbone of the nation’s healthcare system, is at the risk of
collapse. Patients are dissatisfied due to poor access to care, and physicians
are unhappy and burning out with an enormous amount of tasks. To improve the
primary care access, many healthcare organizations have introduced electronic
visits (or e-visits) to provide patient– physician communications through
securing messages. In this paper, we introduce an analytical model to study
e-visits in primary care clinics. Analytical formulas to evaluate the mean and
variance of the patient length of visit in primary care clinics with e-visits
are derived. System properties are investigated. In addition, comparisons of
different scheduling policies between the office and the e-visits are carried
out. The first come first serve, preemptive-resume, and non-preemptive policies
are studied and the results show that the first come first serve policy
typically leads to the best performance.
