Abstract P2047: Provider understanding of coronary artery calcium testing in ASCVD risk stratification and associated racial disparities

Abstract

Background: Coronary Artery Calcium (CAC) scoring is critical in assessing Atherosclerotic Cardiovascular Disease (ASCVD) risk. However, many primary care physicians lack confidence and familiarity with its application. Significant racial disparities in CAC scoring utilization may affect patient outcomes. Objective/Hypothesis: We hypothesized that a brief educational intervention would enhance physicians' confidence, knowledge, and utilization of CAC scoring and awareness of racial disparities. Methods: A pre- and post-intervention study (Image 1) was conducted among 39 physicians at the University of Louisville. The intervention included a 20-minute educational session on CAC scoring and racial disparities, along with a video summarizing the ACC2018 guidelines. A summary of key points for clinical practice and ASCVD plus calculator app was provided. Data were collected using a structured questionnaire before and after the intervention. Viewing time and engagement were recorded. Descriptive and inferential statistics analyzed the data. Results: The average correct physician responses increased from a mean of 59.5% pre-intervention to 92.0% post- intervention. Post-intervention, the number of physicians who felt confident or very confident in CAC testing increased from 17.9% to 94.8%. Thirty-three out of 39 physicians (84.6%) reported likely to use CAC testing more frequently. Correct responses on racial disparities improved from 59% pre-intervention to 92.0% post-intervention. (Image 2). The average viewing time was 28 minutes. Time spent on the questionnaires was 14 min pre and 12 min post. Conclusion: Our targeted educational intervention significantly enhanced physicians' knowledge and confidence in CAC scoring for ASCVD risk assessment and raised awareness about racial disparities, promoting more equitable practices.
