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.
对两个拥有相似患者群体的独立初级保健诊所进行比较，结果显示在生产率方面存在显著差异。在生产率更高的诊所雇佣了一名护士临床医生。她每年独立管理1848次患者就诊，否则这些就诊将需要医生投入时间和精力。她通过执行一些医生在他们共同管理的就诊过程中通常会执行的任务，提高了医生的生产率。主要是因为实践二中的医生得到了护士临床医生的协助，所以其生产率比实践一中的医生高出12%。在标准工作日内，护士临床医生和医生共同管理的患者就诊次数比实践一中的医生多31%，即每年相差2856次患者就诊。这种年度差异是基于一个其他诊所也能匹配的工作时间表：每天工作8小时，每年工作240天。
