Objective: To determine the influence of study methods on American Boa
rd of Surgery (ABS) examination performance. Design: Performance on AB
S examinations by and faculty evaluations of 54 categorical surgical r
esidents from 1976 to 1992 were correlated with the residents' use of
commonly available educational methods (textbooks, Selected Readings i
n General Surgery, grand rounds, preceptor guidance, clinical surgery
review courses, surgical science review courses, Surgical Education an
d Self-Assessment Program [SESAP], and continuing medical education le
ctures) in early, late, and after residency. Setting: An average-sized
midwestern US university surgical residency. Results: Residents who c
onsistently scored above the 33rd percentile on ABS examinations had u
sed texts early, Selected Readings later, and SESAP after residency mo
re frequently than those with ABS In-Training Examination scores in th
e lower one third. Selected Readings and clinical review courses were
associated with significant increases in ABS percentile scores when us
ed in late or after residency and, along with SESAP, were used when re
sidents improved their low ABS In-Training Examination scores. Conclus
ions: Independent study methods are the most effective pathway to succ
essful ABS examination performance. Formal surgical review courses may
help improve the ABS examination scores of residents at a higher risk
of failure.
