BackgroundPrimary aldosteronism (PA) accounts for 3.2-12.7% of hypertension in primary care but is often diagnosed late, if at all. A delayed or missed diagnosis leads to poor blood pressure control and greater cardiovascular risk.AimsTo analyse the impact of Victoria's first dedicated endocrine hypertension service (EHS) on the pattern of PA diagnosis.MethodsSocio-demographic and clinical data from all patients who attended the EHS since July 2016 (n = 267) was collected prospectively. Patients were divided into Year 1 (Y1), Year 2 (Y2) and Year 3 (Y3), based on their first visit.ResultsThe proportion of primary care referrals increased (20% in Y1, 47% in Y2, 52% in Y3) with more referrals being made for treatment-naive hypertension (3% in Y1, 14% in Y2, 19% in Y3). Among PA patients, the median duration of hypertension prior to their first visit decreased (11 years in Y1, 10 years in Y2, 7 years in Y3), and the prevalence of end-organ damage decreased (44% in Y1, 42% in Y2, 33% in Y3). Targeted management of PA improved clinical and biochemical outcomes. The average blood pressure reduction following targeted management increased from 16/12 mmHg in Y1 to 23/12 mmHg in Y3.ConclusionThe EHS, with its strong component of general practitioner engagement, led to increased primary care referrals and PA detection earlier in the course of hypertension. Referred patients were on fewer antihypertensives and had less end-organ damage which simplified the diagnostic process, allowing targeted treatment to be commenced earlier and patient outcomes optimised.© 2020 Royal Australasian College of Physicians.
