This study evaluates the efficacy of MayoExpertAdvisor (MEA), a knowledge delivery tool, to improve adherence to best practices for patients with hyperlipidemia, atrial fibrillation and heart failure. Half of the clinicians will receive MEA, while the other half will not receive MEA.

The investigators hypothesize care teams with access to MEA will act upon recommendations at a higher rate than those care teams in the standard of care arm without access to MEA.

MEA is designed to increase adherence to consensus national guidelines and quality measures which are the standard of care for hyperlipidemia, atrial fibrillation, and heart failure. These diseases were selected based on national data which suggest there is less than optimal adherence to standard of care therapy and this non-adherence is associated with adverse cardiovascular outcomes.

There are 29 care teams in the Employee and Community Health (ECH) practice. Care teams are comprised of 4-8 clinicians who provide primary care to between 3,000 and 8000 patients. 8 care teams are resident/fellow led and will be excluded from the study. The remaining 21 care teams in the ECH practice will be stratified by clinic location and provider specialty (Internal Medicine, Family Medicine). 20 care teams will then be cluster-randomized to either the intervention arm or standard of care arm.

Prior to randomization, clinicians in both arms will receive the same educational module to the current guidelines for management of the atrial fibrillation, heart failure and hyperlipidemia. Clinicians in the intervention arm will receive training by the research team on the use of MEA. This training will clearly inform clinicians that they are always to use their best clinical judgment.
