A retrospective analysis of neurogenic orthostatic hypotension in long-term care facility residents with recurrent falls

Abstract

IntroductionApproximately 50 % of residents in long-term care facilities fall yearly and orthostatic hypotension accounts for a significant portion of them. Neurogenic orthostatic hypotension - a subtype of orthostatic hypotension – is important to be recognized as its management is far more complex; undertreatment of these older adults can lead to recurrent falls, high healthcare cost burden, and increased morbidity and mortality. The primary purpose of our study was to describe the rate of neurogenic orthostatic hypotension in older adults in a long-term care facility, with a secondary purpose to describe risk factors for neurogenic orthostatic hypotension in this population. MethodsWe conducted a retrospective case-control study of residents with recurrent falls at the Dayton Veteran's Affairs long-term care facility. Charts were manually reviewed. Inclusion criterion was three or more falls and age 65 or greater; we did not have exclusion criteria.ICD10 codes and most recent primary care physician notes were used to identify comorbidity diagnoses. Recent orthostatic vitals were used to assess orthostatic hypotension or neurogenic orthostatic hypotension diagnoses. ResultsOf our sample of 224 residents, we observed a prevalence of 20.5 % for neurogenic orthostatic hypotension and 32.1 % for orthostatic hypotension. Neither of them had diagnosis of neurogenic orthostatic hypotension documented. Parkinson's disease was associated with neurogenic orthostatic hypotension (OR-4.3; p = 0.002). Hypertension was prevalent in 69.6 % of residents with orthostatic vitals suggestive of neurogenic orthostatic hypotension. ConclusionOlder adults with recurrent falls at a long-term care facility meet criteria for neurogenic orthostatic hypotension diagnosis far more often than is documented. Common comorbidities associated with neurogenic orthostatic hypotension in this population include Parkinson's disease.
