Translating evidence-based information into effective risk communication: current challenges and opportunities

Area of Science:

• Medical Decision Making
• Health Communication
• Clinical Practice

Background:

• Physicians possess improved tools for risk communication due to medical advances and accessible information.
• Despite these advances, significant variability exists in physician test-ordering practices.
• Factors influencing test ordering include specialization, practice setting, location, defensive medicine, and patient requests.

Purpose of the Study:

• To explore the challenges and factors influencing physician test ordering and risk communication.
• To identify limitations in physician and patient understanding of statistical concepts in healthcare.
• To examine the effectiveness of different risk communication modalities.

Main Methods:

• Literature review and analysis of factors affecting physician test ordering.
• Assessment of physician and patient comprehension of statistical terms and risk communication formats.
• Evaluation of various quantitative and qualitative risk communication strategies.

Main Results:

• Physician test ordering is influenced by diverse factors, including specialization, practice, location, defensive practices, and patient requests.
• Both physicians and patients exhibit limited understanding of statistical terms like pretest/posttest probabilities and "number needed to treat".
• Natural frequency presentation may enhance understanding, but consensus on optimal risk communication modalities is lacking.

Conclusions:

• Effective risk communication requires patient-centered approaches, trust-building, and collaborative decision-making.
• Future research should investigate novel risk communication methods tailored to patient and physician characteristics.
• Identifying the best modalities for translating evidence into understandable risk information is crucial.
