National study of physician awareness and adherence to cardiovascular disease prevention guidelines

Area of Science:

• Cardiology
• Preventive Medicine
• Health Disparities

Background:

• Limited data exist on physician adherence to cardiovascular disease (CVD) prevention guidelines by specialty and patient characteristics, especially gender.
• Physician awareness, adoption, and barriers to national CVD prevention guidelines require further investigation.

Purpose of the Study:

• To evaluate physician adherence to CVD prevention guidelines.
• To assess physician accuracy in risk stratification and guideline application based on patient gender.
• To identify factors influencing CVD preventive recommendations.

Main Methods:

• An online survey of 500 physicians (primary care, obstetrics/gynecology, cardiology) assessed guideline awareness and barriers.
• An experimental case study design evaluated risk assessment and guideline application for simulated patients.
• The Framingham risk score was used to assess intermediate-risk patients.

Main Results:

• Intermediate-risk women were more likely than men to be assigned lower risk categories by physicians (P<0.0001).
• Risk assignment significantly predicted recommendations for lifestyle changes and preventive medication.
• Gender disparities in preventive care were largely explained by perceived risk, with women receiving less aspirin and more weight management advice.

Conclusions:

• Physician perception of risk, not just calculated risk, drives CVD preventive recommendations.
• Gender disparities in CVD prevention stem from underestimation of women's risk.
• Physician education is essential to enhance CVD preventive care quality and reduce morbidity/mortality.
