Analysis of Performance Trends from 2010-2019 on the American Board of Internal Medicine Nephrology Certifying Exam.

BACKGROUND: The pass rate on the American Board of Internal Medicine (ABIM) nephrology certifying exam has declined and is among the lowest of all internal medicine (IM) subspecialties. In recent years, there have also been fewer applicants for the nephrology fellowship match. METHODS: This retrospective observational study assessed how changes between 2010 and 2019 in characteristics of 4094 graduates of US ACGME-accredited nephrology fellowship programs taking the ABIM nephrology certifying exam for the first time, and how characteristics of their fellowship programs were associated with exam performance. The primary outcome measure was performance on the nephrology certifying exam. Fellowship program pass rates over the decade were also studied. RESULTS: Lower IM certifying exam score, older age, female sex, international medical graduate (IMG) status, and having trained at a smaller nephrology fellowship program were associated with poorer nephrology certifying exam performance. The mean IM certifying exam percentile score among those who subsequently took the nephrology certifying exam decreased from 56.7 (SD, 27.9) to 46.1 (SD, 28.7) from 2010 to 2019. When examining individuals with comparable IM certifying exam performance, IMGs performed less well than United States medical graduates (USMGs) on the nephrology certifying exam. In 2019, only 57% of nephrology fellowship programs had aggregate 3-year certifying exam pass rates ≥80% among their graduates. CONCLUSIONS: Changes in IM certifying exam performance, certain trainee demographics, and poorer performance among those from smaller fellowship programs explain much of the decline in nephrology certifying exam performance. IM certifying exam performance was the dominant determinant.

Effect of Access to an Electronic Medical Resource on Performance Characteristics of a Certification Examination: A Randomized Controlled Trial.

BACKGROUND: Electronic resources are increasingly used in medical practice. Their use during high-stakes certification examinations has been advocated by many experts, but whether doing so would affect the capacity to differentiate between high and low abilities is unknown. OBJECTIVE: To determine the effect of electronic resources on examination performance characteristics. DESIGN: Randomized controlled trial. SETTING: Medical certification program. PARTICIPANTS: 825 physicians initially certified by the American Board of Internal Medicine (ABIM) who passed the Internal Medicine Certification examination or sat for the Internal Medicine Maintenance of Certification (IM-MOC) examination in 2012 to 2015. INTERVENTION: Participants were randomly assigned to 1 of 4 conditions: closed book using typical or additional time, or open book (that is, UpToDate [Wolters Kluwer]) using typical or additional time. All participants took the same modified version of the IM-MOC examination. MEASUREMENTS: Primary outcomes included item difficulty (how easy or difficult the question was), item discrimination (how well the question differentiated between high and low abilities), and average question response time. Secondary outcomes included examination dimensionality (that is, the number of factors measured) and test-taking strategy. Item response theory was used to calculate question characteristics. Analysis of variance compared differences among conditions. RESULTS: Closed-book conditions took significantly less time than open-book conditions (mean, 79.2 seconds [95% CI, 78.5 to 79.9 seconds] vs. 110.3 seconds [CI, 109.2 to 111.4 seconds] per question). Mean discrimination was statistically significantly higher for open-book conditions (0.34 [CI, 0.32 to 0.35] vs. 0.39 [CI, 0.37 to 0.41] per question). A strong single dimension showed that the examination measured the same factor with or without the resource. LIMITATION: Only 1 electronic resource was evaluated. CONCLUSION: Inclusion of an electronic resource with time constraints did not adversely affect test performance and did not change the specific skill or factor targeted by the examination. Further study on the effect of resource inclusion on other examinations is warranted. PRIMARY FUNDING SOURCE: ABIM Foundation.

Characteristics of internal medicine physicians and their practices that have differential impacts on their maintenance of certification.

PURPOSE: One way to ensure quality of health care in the United States is through maintenance of certification (MOC). In this study, the authors explored whether participation in the internal medicine MOC program varies by physician-level characteristics, professional activities, and the size and location of the practice. They also sought to determine which component of MOC was incomplete for physicians who participated but did not complete the program. METHOD: The authors used a theoretical realist approach to understand whether participation in the American Board of Internal Medicine MOC program varies according to physician and practice characteristics. The data came from a study sample that consisted of all physicians whose original certification was granted in internal medicine from 1990 through 1999; the study was conducted in 2013. Chi-square tests of independence and a multinomial logistic regression were conducted to determine which physician-level characteristics, professional activities, and practice characteristics were significantly associated with MOC participation. RESULTS: Results showed that physicians who completed MOC tended to have higher certification exam scores; were younger; were U.S. medical graduates; practiced as subspecialists and in the Midwest; spent more time in patient care, teaching, or administration; worked in nonsolo practices; or were employed in counties with less than 20% of persons in poverty. CONCLUSIONS: As certifying boards evaluate their programs, they need to continuously improve their features to assure the public that physicians maintaining certification are providing high-quality patient care.
