Objective:

To evaluate the association between ACGME Milestone competency ratings for PCPs near residency completion and their early-career antibiotic prescribing patterns for older adults.

Approach:
  • Cohort Selection: Included 47,591 internal medicine residents and 22,833 family medicine residents, excluding those without an NPI, not in primary care, or lacking Medicare claims to ensure a focus on relevant prescribing patterns.
Key Findings:
  • Physician-level variation in antibiotic prescribing remains unexplained despite known influencing factors.
  • Residency training may imprint enduring practice patterns, affecting antibiotic prescribing behaviors.
  • No prior investigations have linked standardized competency assessments to prescribing patterns post-graduation.
Interpretation:

The study aims to identify the relationship between residency training characteristics and early-career antibiotic prescribing, focusing on the potential impact of competency ratings.

Limitations:
  • The study relies on secondary data, which may have inherent limitations.
  • Competency ratings may vary across residency programs, affecting comparability.
Conclusion:

The findings could provide insights into how residency training influences antibiotic prescribing practices among early-career PCPs.
