Although physician turnover in a healthcare organization can incur substantial costs, little formal attention has been given to estimating or modeling the financial impact on revenues. Published in the Journal of Medical Practice Management, the current study proposes a model by which to estimate the impact on revenue of physician turnover. The authors design a model that accounts for the physician’s departure, the search period for a successor physician, the time and rate at which the incoming physician increases initial productivity to reach the practice norm, and the ability of the remaining physicians in the practice to recover revenue during the search period.
