Improving diagnosis of primary aldosteronism through education: a modified Delphi study to identify key learning...

Primary aldosteronism (PA) is the most common endocrine cause of secondary hypertension and can be effectively managed, or even cured, with targeted treatment. Despite this, it remains largely undiagnosed leaving a significant patient population with resistant hypertension and modifiable cardiovascular risk.

To determine expert consensus on key information about PA that should ideally be taught to medical students as a step toward improving the detection of this common, underdiagnosed, and often easily treated condition.

The study employed a modified Delphi method which consisted of three rounds, the first of which contained an open-ended question about key areas that experts believe to be most important for inclusion in medical teaching resources and then progressing to assessment of individual versus group rankings of consensus items. Experts included both clinician-educator-researchers and patients with lived experience.

Nine critical knowledge areas in epidemiology, diagnostics, and pathophysiology were identified by the Delphi as consensus items, with the highest ranked being: "PA is common but often under-diagnosed - think about it with every hypertensive patient."

Experts reached a consensus, for the first time, on nine critical knowledge areas about PA that should be covered in medical education. Importantly, the consensus accounted for patients' values and decisions. The results of this study could be used to assess medical student knowledge and their learning resources to facilitate curriculum development and medical resource updates to ensure the timely and accurate diagnosis of PA in hypertensive patients.
