Contribution of a nurse clinician to office practice productivity: comparison of two solo primary care practices.

A comparison of two solo primary care practices with similar patient populations reveals a significant difference in productivity. A nurse clinician was employed in the more productive practice. She independently managed 1,848 patient visits a year that would otherwise have required the time and attention of a physician. She contributed to the productivity of the physician by performing some tasks he would normally have performed during visits they managed jointly. It was primarily because of the assistance he received from the nurse clinician that the physician in practice II was 12 percent more productive than the physician in practice I. The nurse clinician and physician managed 31 percent more patient visits during a standard day than the physician in practice I, or a difference of 2,856 patient visits a year. This annual difference is based on a work schedule that could be matched in other practices: an eight-hour day and a 240-day work year.
