RT Journal Article SR Electronic T1 A Primary Care Panel Size of 2500 Is neither Accurate nor Reasonable JF The Journal of the American Board of Family Medicine JO J Am Board Fam Med FD American Board of Family Medicine SP 496 OP 499 DO 10.3122/jabfm.2016.04.150317 VO 29 IS 4 A1 Melanie Raffoul A1 Miranda Moore A1 Doug Kamerow A1 Andrew Bazemore YR 2016 UL http://www.jabfm.org/content/29/4/496.abstract AB Primary care panel sizes are an important component of primary care practices. Determining the appropriate panel size has implications for patient access, physician workload, and care comprehensiveness and will have an impact on quality of care. An often quoted standard panel size is 2500. However, this number seems to arise in the literature anecdotally, without a basis in research. Subsequently, multiple studies observed that a panel size of 2500 is not feasible because of time constraints and results in incomplete preventive care and health care screening services. In this article we review the origins of a panel size of 2500, review the subsequent work examining this number and effectively debunking it as a feasible panel size, and discuss the importance of primary care physicians setting an appropriate panel size.
