The use of physical restraints in elder care in relation to fall risk

Physical restraints are a frequently used but disputed method to prevent falls. The aim of the present study was to investigate how the use of restraints in institutional elder care relates to previous falls and to the estimated fall risk of the individual patient. A total of 1142 patients, mean age 82 years, were included in the study. A questionnaire, the Multi-Dimensional Dementia Assessment Scale (MDDAS), was used to measure motor function, vision, hearing, ADL performance, behavioral symptoms, psychiatric symptoms, cognitive impairment and use of medication. Questions concerning the use of physical restraints and known previous falls were added to the instrument. Based on data from the questionnaire (MDDAS), a score on the Downton Fall Risk Index was calculated for each patient. All in all, 248 (22%) of the patients had been subject to restraints and for 155 of them (14%) such measures had been taken to prevent falls. Only weak connections were found between the restraining of patients to prevent falls and the prevalence of known previous falls during hospital stay (phi = 0.05), and estimated fall risk (phi = 0.07). The results indicate that the use of physical restraints is poorly connected with the estimated fall risk. Therefore, this study may point to a possible overuse of these measures.
