Five health status instruments were administered in random order to 50 arthritis patients before and after total joint arthroplasty. Relative efficiency and sensitivity in measurement of change in pain, mobility and physical function, social role and social activity, and global health were assessed. The instruments had highly correlated scores, but had differences in certain dimensions. Inter-instrument differentials were larger for social and global outcomes than for pain or mobility. NO single instrument consistently outperformed the others. A method for determining relative efficiency is described.
对50名关节炎患者在全关节置换术前和术后以随机顺序使用了五种健康状况评估工具。评估了这些工具在测量疼痛、活动能力、身体功能、社会角色和社会活动以及整体健康状况变化方面的相对效率和敏感性。这些工具的得分高度相关，但在某些维度上存在差异。社会和整体结果方面的工具间差异大于疼痛或活动能力方面的差异。没有一种工具始终优于其他工具。描述了一种确定相对效率的方法。
