这项研究评估了使用步行速度作为功能和健康状况的指标，在急性病，住院，老年男性退伍军人。对退伍军人事务部（VA）老年评估和管理（GEM）研究中的住院患者（n = 1，388，年龄74.2 ± 5.7，98%为男性）进行了为期1年的随访。结果表明，基线步行速度每降低0.10 m/s，健康状况就会变差（36项简表[SF-36] β = 4.5 [95%置信区间（CI）2.8 - 6.1]），身体功能较差（beta = 2.1 [6.9至14.8]），更多残疾（β = 0.63 [0.53至0.73]），额外康复访视（2.0 [1.4至2.5]），增加内科-外科就诊次数（2.8 [1.9至3.7]），住院时间延长（2.2 [1.4至2.9]），费用增加（1，334美元[869美元至1，798美元]）。此外，步行速度每增加0.10米/秒/年，健康状况就会改善（SF-36 β = 8.4 [6.0至10.7]），身体功能改善（beta = 2.9 [2.5至3.3]），基本残疾较少（0.30 [0.2至0.4]），工具性残疾较少（0.7 [0.6至0.8]），住院天数减少（2.3 [1.3至3.3]），1年费用减少1，188美元[-65美元至2，442美元]。步行速度是有用的功能评估急性病，住院老年人。测量一段时间内的步行速度可能有助于预测那些需要和使用更多健康相关服务的人。
This study evaluated the use of walking speed as an indicator of function and health status in acutely ill, hospitalized, older male veterans. Hospital inpatients in a Department of Veterans Affairs (VA) study of Geriatric Evaluation and Management (GEM) (n = 1,388, age 74.2 +/- 5.7, 98% male) were followed for I year. The results indicate that each 0.10 m/s reduction in baseline walking speed was associated with poorer health status (36-item short form [SF-36] beta = 4.5 [95% confidence interval (CI) 2.8 to 6.1]), poorer physical functioning (beta = 2.1 [6.9 to 14.8]), more disabilities (beta = 0.63 [0.53 to 0.73]), additional rehabilitation visits (2.0 [1.4 to 2.5]), increased medical-surgical visits (2.8 [1.9 to 3.7]), longer hospital stays (2.2 [1.4 to 2.9]), and higher costs ($1,334 [$869 to $1,798]). In addition, each 0.10 m/ s/yr increase in walking speed resulted in improved health status (SF-36 beta = 8.4 [6.0 to 10.7]), improved physical function (beta = 2.9 [2.5 to 3.3]), fewer basic disabilities (0.30 [0.2 to 0.4]), fewer instrumental disabilities (0.7 [0.6 to 0.8]), fewer hospitalization days (2.3 [1.3 to 3.3]), and 1-year cost reductions of $1,188 [-$65 to $2,442]. Walking speed is useful for the functional assessment of acutely ill, hospitalized older adults. Measurement of walking speed over time may help predict those who will need and use more health-related services.
