The study examined the impact of dementia severity on repeat fallers among the institutionalized elderly. A secondary analysis of a dataset containing information on 466 residents (86 of whom were fallers) of nine care facilities around Tokyo was carried out. Descriptive statistics were used to determine the baseline characteristics. Then, logistic regression analysis was carried out to identify the risk factors between the non-fallers and fallers and between the single and repeat fallers. Finally, the relative risks that had an impact on the repeat fallers were calculated. Sixty-one persons (13.1%) were identified as single fallers and 25 (5.4%) were identified as repeat fallers. An unstable gait was a dominant risk factor. In addition, the person's sex and the facility type were identified as risk factors for the fallers, while severe dementia was identified as a risk factor for the repeat fallers. Nurses should recognize the combination of severe dementia and unstable gait as a warning sign for potential repeat fallers.
本研究考察了痴呆严重程度对机构老年人中复发性跌倒者的影响。对东京周边 9 家护理机构的 466 名居民（其中 86 人是跌倒者）的数据集进行了二次分析。使用描述性统计数据确定基线特征。然后，进行逻辑回归分析，以确定非跌倒者和跌倒者以及单次跌倒者和复发性跌倒者之间的风险因素。最后，计算了对复发性跌倒者有影响的相对风险。61 人（13.1%）被确定为单次跌倒者，25 人（5.4%）被确定为复发性跌倒者。不稳定的步态是主要的危险因素。此外，患者的性别和机构类型被确定为跌倒者的危险因素，而严重痴呆被确定为复发性跌倒者的危险因素。护士应将严重痴呆和不稳定步态的组合视为潜在复发性跌倒者的警告信号。
