Associations Between Physician Continuous Professional Development and Referral Patterns: A Systematic Review and...

Area of Science:

• Health Services Research
• Medical Education

Background:

• Clinician referral patterns are crucial for high-value healthcare.
• Both overuse and underuse of referrals can negatively impact patient care and resource allocation.

Purpose of the Study:

• To systematically review and synthesize research on the association between physician continuous professional development (CPD) and referral patterns.
• To understand how CPD interventions affect the direction and appropriateness of clinician referrals.

Main Methods:

• A comprehensive literature search was conducted across major databases (MEDLINE, Embase, PsycInfo, Cochrane) for comparative studies on physician CPD and referral outcomes.
• Two independent reviewers screened articles, extracted data, and performed meta-analysis on quantitative results.
• Outcomes included referral rates, intended direction of change, and referral appropriateness.

Main Results:

• 31 studies involving over 14,000 physicians and 381,000 referrals were included.
• CPD significantly increased referrals by 91% (RR 1.91) and decreased referrals by 32% (RR 0.68) when intended.
• Various instructional approaches and durations showed favorable effects, but no single CPD method was superior in head-to-head comparisons.

Conclusions:

• Continuous professional development (CPD) demonstrates a statistically significant impact on physician referral rates, aligning with the intended changes.
• Further research is needed to compare the effectiveness of different CPD interventions specifically on referral outcomes.
