Stricter state continuing medical education (CME) requirements improved physician clinical knowledge, as measured by Maintenance of Certification (MOC) exam scores. This suggests CME mandates enhance doctors' medical expertise.
Area of Science:
- Medical Education Research
- Physician Performance Evaluation
- Public Health Policy
Background:
- Continuing Medical Education (CME) aims to maintain and improve physician knowledge.
- The impact of varying state-mandated CME requirements on clinical knowledge remains an area of investigation.
- Maintenance of Certification (MOC) examinations offer a standardized measure of physician knowledge.
Purpose of the Study:
- To assess the influence of state-mandated CME requirements on the clinical knowledge of general internists.
- To determine if changes in CME policies correlate with measurable improvements in physician knowledge.
Main Methods:
- Utilized a difference-in-differences methodology analyzing data from 19,563 general internists who took the Internal Medicine MOC exam (2006-2013).
- Leveraged natural variations in state CME requirements over time as a quasi-experimental design.
- Compared MOC examination performance 10 years apart, controlling for physician demographics and fixed effects.
Main Results:
- Increased CME credit-hour requirements were associated with a significant improvement in MOC examination performance.
- This improvement was equivalent to a 4-percentile point increase in examination scores (from 50th to 54th percentile).
Conclusions:
- Mandatory CME requirements, particularly those involving summative knowledge assessments, are linked to enhanced physician clinical knowledge.
- State policies on continuing medical education can effectively contribute to maintaining and advancing physician competency.
