Studies of selected indicators of the process of care provided by a Medex and by a physician preceptor in seven rural practices suggest that the Medex is more likely to use appropriate laboratory tests and less likely to use inappropriate treatments. When outcomes of care were determined in 13 practices with a Medex and a preceptor, the patients seen by the Medex tended to fare about as well as those seen by a physician (71% versus 74%, respectively) in regaining their usual functional status. The addition of a Medex to a rural practice may thus produce both direct and indirected benefits.
对在七个乡村诊所中由医学助理（Medex）和带教医师提供的护理过程的选定指标进行的研究表明，医学助理更有可能使用适当的实验室检查，而不太可能使用不适当的治疗方法。在有医学助理和带教医师的13个诊所中确定护理结果时，由医学助理诊治的患者在恢复其通常功能状态方面的情况与由医师诊治的患者大致相同（分别为71%和74%）。因此，在乡村诊所增加一名医学助理可能会产生直接和间接的益处。
