Improving Passage Rate on USMLE Step 2 Clinical Skills: Results from a Pilot Program

In the United States (US), successful passage of United States Medical Licensing Examination (USMLE) Step 2 Clinical Skills (Step 2 CS) is required to enter into residency training. In 2017, the USMLE announced an increase in performance standards for Step 2 CS. As a consequence, it is anticipated that the passage rate for the examination will decrease significantly for both US and international students. While many US institutions offer a cumulative clinical skills examination, their effect on Step 2 CS passage rates has not been studied. The authors developed a six-case, standardized patient (SP)-based examination to mirror Step 2 CS and measured impact on subsequent Step 2 CS passage rates. Students were provided structured quantitative and qualitative feedback and were given a final designation of "pass" or "fail" for the practice examination. A total of 173 out of 184 (94.5%) students participated in the examination. Twenty SPs and $26,000 in direct costs were required. The local failure rate for Step 2 CS declined from 4.5% in the year proceeding the intervention to 2.1% following the intervention. In the same timeframe, the US failure rate for Step 2 CS increased from 3.8 to 5.1%, though the difference between local and national groups was not significantly different ( P  = .07). Based on the initial success of the intervention, educational leaders may consider developing a similar innovation to optimize passage rates at their institutions.
