An analysis of programs and positions in the first year of graduate medical education regarded as acceptable by U.S. medical students suggests that the ratio for all positions is about one per graduate and even less in primary care programs. Since approximately 95 percent of positions are now in institutions affiliated with academic health centers, these medical-school-hospital complexes should be supported to increase positions in primary care programs in order to accommodate the two-thirds of U.S. graduates who want to begin their graduate medical education in these disciplines.
一项对美国医学院学生认为可接受的毕业后医学教育第一年的项目和职位的分析表明，所有职位的比例约为每毕业生一个职位，而在初级保健项目中甚至更低。由于目前约95%的职位在与学术健康中心相关的机构中，这些医学院与医院的联合体应得到支持，以增加初级保健项目中的职位，以便容纳三分之二希望在这些学科开始毕业后医学教育的美国毕业生。
