Orthostatic hypotension and overall mortality in 1050 older patients of the outpatient comprehensive geriatric assessment unit

AimOrthostatic hypotension is a common problem in individuals aged 65years. Its association with mortality is not clear. The aim of the present study was to evaluate associations between orthostatic hypotension and overall mortality in a sample of individuals aged 65years who were seen at the Outpatient Comprehensive Geriatric Assessment Unit, Clalit Health Services, Beer-Sheva, Israel. MethodsIndividuals who were evaluated in the Outpatient Comprehensive Geriatric Assessment Unit between January 2005 and December 2015, and who had data on orthostatic hypotension were included in the study. The database included sociodemographic characteristics, body mass index, functional and cognitive state, geriatric syndromes reached over the course of the assessment, and comorbidity. Data on mortality were also collected. ResultsThe study sample included 1050 people, of whom 626 underwent comprehensive geriatric assessment and 424 underwent geriatric consultation. The mean age was 77.35.4years and 35.7% were men. Orthostatic hypotension was diagnosed in 294 patients (28.0%). In univariate analysis, orthostatic hypotension was associated with overall mortality only in patients aged 65-75years (HR 1.5, 95% CI 1.07-2.2), but in the multivariate model this association disappeared. ConclusionsIn older frail patients, orthostatic hypotension was not an independent risk factor for overall mortality. Geriatr Gerontol Int 2018; 18: 1009-1017.
