Few outcome assessments are published from complementary and alternative medicine (CAM) practices. We aimed to describe patient and practice characteristics of ND care for hypertension (HTN), quantify changes in blood pressure (BP), and evaluate the proportion achieving control of HTN during care. A retrospective, observational study of ND practice in HTN was performed in an outpatient clinic in WA State. Eighty-five charts were abstracted for the final analysis. At initiation of care, the mean patient age was 61 years, with 51% having stage 2 HTN, despite common use of anti-hypertensive medications (47%). Patients with both stage 1 and stage 2 HTN appeared to improve during care, with stage 2 patients achieving mean reductions of −26 mmHg ( 𝑃 < . 0 0 0 1 ) and −11 mmHg ( 𝑃 < . 0 0 0 1 ) in systolic BP (SBP) and diastolic BP (DBP), respectively. The proportion of patients achieving control (<140/90 mmHg) in both SBP and DBP was increased significantly from 14 to 44% ( 𝑃 < . 0 3 3 ), although the statistical significance was not maintained upon correction for multiple comparisons. BP appears to improve during ND care for HTN, in a high-risk population. Randomized trials are warranted.
