0068/2017 - Quedas recorrentes e fatores de risco em idosos institucionalizados. Recurrent falls and risk factors among institutionalized older people.
Queda recorrente representa alto risco de morbidade e mortalidade em idosos, principalmente institucionalizados, dado ao seu quadro de fragilidade e declínio funcional evidentes. O objetivo deste estudo é determinar a incidência e os fatores de risco relacionados a quedas recorrentes em idosos institucionalizados. Trata-se de um estudo longitudinal tipo coorte no período de um ano. Foram avaliados indivíduos com 60 anos ou mais residentes em 10 Instituições de Longa Permanência para Idosos, que deambulassem e possuíssem capacidade cognitiva preservada. Foi questionada a ocorrência de quedas nos últimos doze meses, considerando recorrentes a ocorrência de dois ou mais episódios neste período. Foram ainda coletadas variáveis referentes à instituição, condições sócio demográficas e de saúde do idoso através de questionários. Do total de 364 idosos, 130 foram incluídos. A incidência de quedas recorrentes foi de 26.9% (IC 95% = 22.4 – 31.5). A partir do Qui-quadrado e Regressão Logística, considerando o nível de significância de 5%, foi encontrada fadiga como fator de risco (p=0.001; RR=2.9) e uso de betabloqueadores como fator de proteção (p=0.010; RR=0.1). Conclui-se que queda recorrente é comum nas Instituições de Longa Permanência para Idosos e a fadiga representa fator de risco.

Abstract:
Recurrent falls lead to high risk of morbidity and mortality in older people, especially among institutionalized individuals, due to their frailty status and functional decline. The aim of this study is to determine the incidence and risk factors related to recurrent falls in institutionalized older people. This is a longitudinal cohort study during a one-year period. Older residents10 nursing homes who were able to walk and preserved cognitive capacity were assessed. Occurrence of falls in the last twelve months was asked and, recurrent falls were considered when the individual suffered two or more falls during this period. Besides, institution-related variables as well as sociodemographic and health conditions were collected through questionnaires. Among a total of 364 older people, 130 were included. The incidence of recurrent falls was 26.9% (95% CI = 22.4 - 31.5). Through the chi-square and logistic regression, considering a 5% significance level, fatigue was identified as a risk factor (p = 0.001; RR = 2.9) and beta-blockers as a protective factor (p = 0.010; RR = 0.1). It can be concluded that recurrent falls are common in nursing homes and fatigue represents a risk factor.
