BACKGROUND:
The BASIC Examination was added to the US examination system for anesthesiology certification in 2014. The American Board of Anesthesiology conducted retrospective analyses to assess whether resident demographics, program characteristics, and/or prior examination performance were associated with first-time BASIC pass rates
METHODS:
Anesthesiology residents who took the BASIC Examination for the first time from July 2014 to November 2022 were eligible to participate, and they had at least 2 more attempts (or opportunities to attempt) through December 2023. First-time and eventual pass rates (ie, based on up to 3 attempts) were calculated for each demographic group. For those residents who had the clinical base year in-training examination (CBY ITE) scores available, demographic group performance differences on this examination were first examined. Mixed-effects logistical regression models assessed how resident demographics, program characteristics, and/or prior CBY ITE scores were associated with the odds of passing the BASIC the first time.
RESULTS:
The analyses included 17,286 examination attempts from 15,789 residents. The majority of residents were male (65.8%), non-Hispanic or Latino (76.2%), White (47.8%), and US medical school graduates (87.4%). Differences in the first-attempt BASIC pass rates included male (92.7%) vs female (88.1%), non-Hispanic or Latino (92.0%) vs Hispanic or Latino (85.8%), Asian (92.6%) and White (92.4%) vs Black/African American (81.9%), respectively, and US (91.5%) vs international (88.6%) medical school graduates. Females had significantly lower odds of passing the BASIC the first time than males (odds ratio [OR] = 0.53, 95% confidence interval [CI], 0.47–0.60); Black/African American residents (OR = 0.41, 95% CI, 0.33–0.51) and Middle Eastern or North African residents (OR = 0.64, 95% CI, 0.46–0.91) had lower odds of passing the BASIC on first attempt than White residents; Hispanic or Latino residents had lower odds of passing the BASIC initially than non-Hispanic or Latino residents (OR = 0.52, 95% CI, 0.42–0.64). Nevertheless, all demographic subgroups’ eventual pass rates were >99%.
Male and White residents outperformed female and Black/African American residents, respectively, in CBY ITEs. The gender and race performance gaps in the first-time BASIC pass rates were attenuated but not eliminated after controlling for their CBY ITE scores—compared to male and White residents, respectively, the odds of passing the BASIC the first time changed from 46% to 56% for female residents, and from 41% to 53% for Black/African American residents.
CONCLUSIONS:
Female and nonwhite residents had lower first-time BASIC Examination pass rates. Almost all trainees passed by their up-to-third attempts. Future studies are needed to understand the basis of these differences and identify opportunities for improvement.
