Background: The UPMC Pathology Residency program is an ACGME fully accredited program. The training is based on a “Center of Excellence” model in which residents rotate through sub-specialty anatomic and clinical pathology rotations. The UPMC rolling pass average for the ABP exam is above the national average, but factors predicting success or failure are unknown. The aim of this study is to investigate if the USMLE Step 1 percentile score is a predictor for ABP performance in the UPMC pathology program.
Design: Nine years of data (2001-2009) from UPMC Pathology Residents (n=72) were collected from existing files and de-identified. Five residents with incomplete data were excluded from analysis, leaving 93.1% of the resident sample, including two residents with USMLE equivalent scores. Step 1 USMLE percentile score and ABP failure rate for first time takers were compared. Results are reported as percentage of residents who failed the ABP exam, cohorted by USMLE percentile scores (≤80, 81-85, 86-89, ≥90).
