Knowledge Gaps and Educational Interventions in Dietary Supplement Regulations Among Resident Physicians

Area of Science:

• Medical Education
• Pharmacology
• Public Health

Background:

• Increased dietary supplement use in the U.S. raises safety concerns due to lack of premarket FDA approval and potential for contamination.
• Physicians historically lack standardized education on dietary supplements, contributing to safety risks.
• Dietary supplements are not subject to the same rigorous approval process as pharmaceuticals.

Purpose of the Study:

• To assess internal resident physicians' knowledge of dietary supplement regulations.
• To evaluate the impact of educational materials on resident physicians' understanding of these regulations.

Main Methods:

• A quasi-experimental quality improvement study design was employed.
• Surveys were administered to resident physicians to gauge knowledge before and after an educational intervention.
• The study was conducted at a community-based academic tertiary care hospital.

Main Results:

• Initial survey showed a 42.8% average knowledge score, with 75% correctly stating supplements lack FDA premarket approval.
• Significant knowledge gaps were identified regarding supplement efficacy, safety, adverse event reporting, and third-party certifications.
• Post-intervention, average knowledge scores rose to 75%, demonstrating significant improvement across all tested FDA regulation aspects.

Conclusions:

• A notable knowledge gap exists among resident physicians concerning the Food and Drug Administration (FDA) regulations for dietary supplements.
• Short, structured educational materials can effectively address and improve physician knowledge in this area.
• Targeted education is crucial for enhancing physician competency in advising patients on dietary supplement use.
