Electronic Alert to Improve Testing For Primary Aldosteronism in Patients With Hypertension

Primary aldosteronism (PA) is common but rarely recognized cause of hypertension that carries excess cardiovascular and renal risk and has approved targeted treatments. Despite current clinical guidelines that recommend screening in a defined set of high-risk populations, less than 5% of eligible patients are ever screened for PA. This study aims to evaluate the impact of a computer decision support Best Practice Advisory (BPA) alert on rates of screening for PA in guideline-eligible patients, referral to specialist PA care, and treatment with mineralocorticoid receptor antagonists.
