Fall assessment in subacute inpatient stroke rehabilitation using clinical characteristics and the most preferred stroke severity and outcome measures

Abstract

Introduction: No single tool is able to distinguish fallers from non-fallers. The aim of this study was to detect subacute stroke inpatients at higher risk for falls, predictors for the number of falls and near falls and the impact of these incidents on functional outcome.Methods: An observational prospective cohort study comparing clinical differences between non-fallers, onetime and repeat fallers. Bivariate and multivariate Poisson regression analyses with length of stay as an offset variable were conducted.Results: Fallers had mostly intermediate level of impairment and disability (NIHSS, FIM, mRS, the ICF minimal generic data set). The onetime fallers who were oldest, most disabled and most often institutionalised achieved the same functional improvement as the non-fallers, however, after significantly longer inpatient rehabilitation. The repeat fallers who were youngest and had the longest rehabilitation in-stay, achieved equal functioning as the non-fallers having faster motor gain and the greatest overall functional improvement compared to the other two subgroups.Conclusions: Right hemispheric stroke, previous myocardial infarction and shorter time from stroke onset were independent predictors for the number of incidents. In the future, larger studies are recommended to investigate fall rate and different severities of incidents, falls and near falls separately.
