BACKGROUND Orthostatic hypotension (OH) measurement reproducibility is poor. Our objectives were to assess feasibility of self-detection home-measured OH (HOH) and HOH determinants. METHODS Subjects older than 65 years, attending a geriatric outpatient clinic, able to understand the HOH protocol: 3 blood pressure (BP) measures after 5 minutes of seating and BP measures after 1 and 3 minutes of standing, each morning and evening for 3 consecutive days were lent a validated digital automatic sphygmomanometer. Reports containing at least 4 correct measurements were deemed a success. Factors associated with HOH were studied. RESULTS HOH feasibility was 82.8% (241 subjects) with no difference between participants who failed or succeeded. Among the 241 subjects (mean age (SD) = 78.0 (8.3) years old; 62.1% of women), 139 were free of HOH, 70 had 1 HOH episode and 32 had 2 or more HOH episodes. Hypertension, dementia, atrial fibrillation, diabetes, and heart failure were found in 70.0%, 10.4%, 9.4%, 8.8%, and 3.4% of cases, respectively. Subjects were treated with antihypertensive, benzodiazepine, statin medication in 47.3%, 9.3%, 7.4% of cases, respectively, and 42.4% experienced polypharmacy. HOH episodes were associated with dementia (P = 0.01), presence of OH during the geriatric outpatient clinic assessment (P = 0.0002), statin therapy (P = 0.04), and polypharmacy (P = 0.0002). In multivariate analysis, benzodiazepine (OR (95% CI) = 2.59 (1.10–6.08) and statin medication (OR (95% CI) = 1.92 (1.10–3.33)) remained significantly associated with HOH. CONCLUSIONS HOH had a good feasibility and relevant determinants. A study to address the predictive value of HOH will be conducted.
