Duties, tasks, knowledge and skills of an obesity medicine physician: A practice analysis

Background

Given the evolving nature of obesity medicine, periodic evaluation of its clinical practice is needed to ensure that certification requirements address real-world experience. Practice analysis is a systematic approach to define a field's body of knowledge, and its results can inform the content outline and examination blueprint for a certification examination. This study describes the 2023 practice analysis conducted by the American Board of Obesity Medicine (ABOM).

Methods

Initially, 14 obesity medicine physicians participated in a practice analysis panel, resulting in 3 duties and 30 tasks required for competent practice of obesity medicine physicians. Each task included steps, knowledge, skills, and abilities needed to perform the task. ABOM then recruited 645 certified obesity medicine physicians from its database to participate in a validation survey to rate the frequency [scale: never (0) to very frequently (5)] and importance [scale: not important (0) to very important (3)] of each task. Survey participants could also provide open-ended comments.

Results

Among validation survey participants (n = 645), the most common primary medical specialties reported were internal medicine (46.0 %), family medicine (33.8 %), and pediatrics (11.2 %). Years practicing obesity medicine varied with 45.3 % reporting 1–4 years, 26.0 % 5–9 years, and 28.7 % ≥ 10 years in practice. Most tasks were performed frequently (mean score ≥4.0) and rated as important (mean score ≥2.0). All tasks were retained based on the frequency and importance ratings. Survey results informed the weighting in the examination blueprint.

Conclusion

There was consensus among practicing ABOM-certified physicians who participated in the validation survey in the tasks required for competent obesity medicine practice. Our practice analysis approach was a structured process that engaged obesity medicine physicians and captured the breadth and depth of knowledge required for obesity medicine. The new content outline and examination blueprint developed will be implemented with the 2025 ABOM certification exam administration.
