There are many types of providers involved in the delivery of healthcare and each plays a unique role. Though there are commonalities, a unique set of metrics is often useful to evaluate the performance of different provider types. The specific metrics selected should depend on the quality and robustness of available data, the ability of providers to control or influence the metric, and the ability to compare the metric across providers in an objective manner. Careful consideration is required to select the best performance metrics to measure and evaluate the performance of healthcare providers.
