Objectives:
The Transfusion Medicine In-Service Examination (TMISE) is offered twice a year to transfusion medicine (TM) fellows. We examined the relationship between TMISE scores and outcomes of the American Board of Pathology (ABP) TM subspecialty certifying examination (TM boards).
Methods:
TM fellowship programs were contacted to provide anonymous data about TM fellows, their scores on TMISE, and outcome of TM boards.
Results:
Of 48 TM fellowship programs contacted, 24 (50%) responded with data for 170 fellows. Average TMISE score of fellows who passed their first TM boards attempt was 71.3, while the average TMISE score of fellows who failed their first TM boards attempt was 64.3 (P = .009).
Conclusions:
TMISE scores correlated with passing TM boards on the first attempt. Fellows who took the TM boards the same year that they graduated from TM fellowship had a significantly higher first-time pass rate than fellows who delayed taking TM boards.
