Three classes of Medex were followed during their preceptorship training and subsequent employment to assess the impact of adding such physician assistants on 13 private practices. The data suggest that the Medex are readily incorporated into the practice, seeing a similar spectrum of patients and generally functioning as a semicolleague. Although the Medex was almost universally a contributing addition to the practice, increasing patient volume, the specific effects varied with the setting.
在他们的带教培训期间及随后的工作中，对三类医学扩展课程毕业生（Medex）进行了跟踪，以评估在13家私人诊所增加此类医师助理的影响。数据表明，医学扩展课程毕业生很容易融入诊所，诊治的患者范围相似，总体上发挥着准同事的作用。尽管医学扩展课程毕业生几乎普遍为诊所做出了贡献，增加了患者数量，但具体效果因诊所环境而异。
