We developed the Nursing Home Life-Space Diameter (NHLSD) as a measure of the extent and frequency of mobility among skilled nursing facility (SNF) residents. Intrarater and interrater reliability was assessed in a small sample of SNF residents. The means and ranges of NHLSD scores, the characteristics associated with NHLSD score, and the association between NHLSD score and other functional characteristics were then determined among 398 residents of 12 SNFs. NHLSD scores ranged from 0, signifying bed- or chair-bound to 50, signifying leaving the facility daily. The correlation between NHLSD scores by two nurses was 0.951; the correlation between scores at two points of time was 0.922. Mean score among the 398 subjects was 27.05. Decreased vision, presence of a neurologic disease, and arthritis were all associated with lower NHLSD score. Mobility (NHLSD) score was moderately correlated with other functional characteristics such as participation in social activities (Spearman's correlation = +0.565). The NHLSD, which represents a simple and reliable assessment of mobility among SNF residents, could be used to assess the effect of interventions and to monitor changes among SNF residents.
我们开发了疗养院生活空间直径（NHLSD），作为衡量专业护理机构（SNF）居民活动范围和频率的指标。在一小部分SNF居民样本中评估了评分者内和评分者间的可靠性。然后在12个SNF的398名居民中确定了NHLSD评分的均值和范围、与NHLSD评分相关的特征以及NHLSD评分与其他功能特征之间的关联。NHLSD评分范围从0（表示卧床或坐轮椅）到50（表示每天离开机构）。两名护士的NHLSD评分之间的相关性为0.951；两个时间点的评分之间的相关性为0.922。398名受试者的平均评分为27.05。视力下降、患有神经系统疾病和关节炎均与较低的NHLSD评分相关。活动能力（NHLSD）评分与其他功能特征（如参与社交活动）中度相关（斯皮尔曼相关性=+0.565）。NHLSD代表了对SNF居民活动能力的简单可靠评估，可用于评估干预措施的效果并监测SNF居民的变化。
