Purpose This study was conducted to determine whether an objective structured clinical examination (OSCE) could be used to evaluate and monitor hand hygiene and personal protective equipment (PPE) proficiency among medical interns in the United States. Methods Interns in July 2015 (N=123, cohort 1) with no experience of OSCE-based contact precaution evaluation and teaching were evaluated in early 2016 using an OSCE for hand hygiene and PPE proficiency. They performed poorly. Therefore, the new interns entering in July 2016 (N=151, cohort 2) were immediately tested at the same OSCE stations as cohort 1, and were provided with feedback and teaching. Cohort 2 was then retested at the OSCE station in early 2017. The Mann-Whitney U-test was used to compare the performance of cohort 1 and cohort 2 on checklist items. In cohort 2, performance differences between the beginning and end of the intern year were compared using the McNemar chi-square test for paired nominal data. Results Checklist items were scored, summed, and reported as percent correct. In cohort 2, the mean percent correct was higher on the posttest than on the pretest (92% vs. 77%, P<0.0001), and the passing rate (100% correct) was also significantly higher on the posttest (55% vs. 16%). At the end of intern year, the mean percent correct was higher in cohort 2 than in cohort 1 (95% vs. 90%, P<0.0001), and 55% of cohort 2 passed (a perfect score) compared to 24% in cohort 1 (P<0.0001). Conclusion An OSCE can be utilized to evaluate and monitor hand hygiene and PPE proficiency among interns in the United States.

在美国进行客观结构化临床检查，以评估和监测实习生的手卫生和个人防护设备使用能力

目的进行这项研究来确定是否可以使用客观结构化临床检查（OSCE）来评估和监测美国医疗实习生的手卫生和个人防护设备（PPE）能力。方法采用OSCE进行手卫生和PPE能力评估，于2016年初对2015年7月（N = 123，队列1）没有基于OSCE接触预防评估和教学经验的实习生进行评估。他们表现不佳。因此，2016年7月进入的新实习生（N = 151，第2组）立即在与第1组相同的OSCE站进行了测试，并获得了反馈和教学。然后，在2017年初在OSCE站对第2组进行了重新测试。使用了Mann-Whitney U检验比较第1组和第2组在清单上的表现。在同类群组2中 使用McNemar卡方检验对成对的名义数据进行比较，比较了实习年开始和结束之间的绩效差异。结果对清单项目进行评分，求和，并报告为正确百分比。在同类研究2中，后测的平均正确率比前测的高（92％vs. 77％，P <0.0001），后测的合格率（100％正确）也显着更高（55％vs 16％）。在实习年末，第二组的平均正确率高于第一组（95％比90％，P <0.0001），并且第二组的55％通过（完美评分），而第二组的这一比例为24％。同类群组1（P <0.0001）。结论OSCE可用于评估和监测美国实习生的手卫生和PPE水平。
