The Barthel Index, originally developed and validated to assess activities of daily living in patients with neuromuscular disorders, is commonly used in research and clinical practice involving critically ill patients.
To evaluate the internal consistency, reliability, measurement error, and construct validity of the Barthel Index used at intensive care unit discharge.
In this observational study, 2 physiotherapists measured the physical functioning of 122 patients at intensive care unit discharge, using the Barthel Index and other measurement instruments.
The patients had a median (IQR) age of 56 (47-66) years, and 62 patients (51%) were male. The primary reason for intensive care unit admission was sepsis (28 patients [23%]), and 83 patients (68%) were receiving mechanical ventilation. The Cronbach α value indicating internal consistency was 0.81. For interrater reliability, the intraclass correlation coefficient for the total score was 0.98 (95% CI, 0.97-0.98; P < .001) and the κ statistic for the individual items was 0.54 to 0.94. The standard error of measurement was 7.22, the smallest detectable change was 20.01, and the 95% limits of agreement were -10.3 and 11.8. The Barthel Index showed moderate to high correlations with the other physical functioning measurement instruments (ρ = 0.57 to 0.88; P < .001 for all).
The Barthel Index is a reliable and valid instrument for assessing physical functioning at intensive care unit discharge.
巴塞尔指数最初是为评估神经肌肉疾病患者的日常生活活动而开发和验证的，常用于涉及重症患者的研究和临床实践。
评估巴塞尔指数在重症监护病房出院时的内部一致性、可靠性、测量误差和结构效度。
在这项观察性研究中，2 名物理治疗师使用巴塞尔指数和其他测量仪器测量了 122 名重症监护病房出院患者的身体功能。
患者的中位（IQR）年龄为 56（47-66）岁，62 名患者（51%）为男性。入住重症监护病房的主要原因是败血症（28 例[23%]），83 例患者（68%）正在接受机械通气。内部一致性的 Cronbach α 值为 0.81。对于评分者间信度，总分的组内相关系数为 0.98（95%CI，0.97-0.98；P<0.001），单个项目的κ值为 0.54 至 0.94。测量误差的标准误差为 7.22，最小可检测变化为 20.01，95%的一致性界限为-10.3 和 11.8。巴塞尔指数与其他身体功能测量仪器之间具有中度至高度相关性（ρ=0.57 至 0.88；所有 P<0.001）。
巴塞尔指数是评估重症监护病房出院时身体功能的可靠和有效的工具。
