Abstract


Purpose: To determine if an objective structured clinical examination (OSCE) could be used to evaluate and monitor hand hygiene and personal protective equipment (PPE) proficiency for medical interns in the United States.

Methods: Interns in July 2015 (N=123, Cohort 1) without OSCE-based contact precaution evaluation and teaching were evaluated early 2016 by OSCE for hand hygiene and PPE proficiency. They performed poorly. Therefore, the new interns entering July 2016 (N=151, Cohort 2) were immediately tested in the same OSCE station as Cohort 1 and provided feedback and teaching. Cohort 2 was then retested in the OSCE station early 2017. The Mann Whitney U test was used to compare Cohort 1 vs. Cohort 2 performances on checklist items. Cohort 2 performance differences at the beginning and end of the intern year were compared using McNemar’s X2 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 in posttest than pretest, 92% vs. 77% )(P <0 .0001). The passing rate (100% correct) was significantly higher, 55% vs. 16%. Comparing Cohort 1 and Cohort 2 at the end of intern year, the mean percent correct was higher for Cohort 2 compared to Cohort 1, 95% vs 90% (P < 0.0001). 55% of the 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 for interns in the United States.
