Background: Competency-based medical education (CBME) is gaining momentum in postgraduate residency and fellowship training. While randomized trials, consensus statements, and practice guidelines can help delineate some of the core competencies for CBME, they are not applicable to all clinical scenarios.
Objective: To propose and assess the feasibility of a practical methodology for addressing this issue using radiosurgery for vestibular schwannoma (VS) science as an example.
Methods: The Web of Science electronic database was searched using relevant terms. A 3-step review of titles and abstracts was used. Studies were classified independently and in duplicate as either efficacy or effectiveness analyses. Cohen's kappa score was used to assess inter-rater agreement.
Results: Overall, 1818 surgical and 943 radiosurgical publications were identified. The number of effectiveness studies surpassed that of efficacy studies in the late 1980s for surgical studies, and in the early-to-mid 1990s among radiosurgical studies. The publication rate was higher for radiosurgery in the mid 1990s, but it paralleled that of surgical studies beyond the early 2000s. Variations in this overall trend corresponded to the emergence of studies that assessed the role of endoscopy and the utility of dose reduction in radiosurgery.
Conclusion: We have confirmed the feasibility and accuracy of this objective methodological approach. By understanding how the peer-reviewed literature reflects actual practice interests, educators can tailor curricula to ensure that trainees remain current. While further validation studies are needed, this methodology can serve as a supplemental strategy for identifying additional core competencies in CBME.
