The Veterans Health Administration recently transformed its primary care system into a team-based care model in which all Veterans are assigned to Patient Aligned Care Teams (PACTs).  These PACTS are constructed with standard ratios of medical staff to patients.  However, these ratios may not be appropriate for trainee clinics, where the volume and complexity of patients and trainee needs are quite variable.  In this paper, we describe our efforts in partnering with the Durham VA Medical Center to develop a discrete event simulation model of a trainee PACT clinic called PRIME.  The objective of this analysis was to develop a tool that identified areas contributing to bottlenecks in the daily functioning of PRIME Clinic to assess means to combat variable demands from variable patient volume. A related component of this analysis was to access if a higher ratio of nurses were needed in trainee clinics compared to traditional PACT models.
