The Michigan Hand outcomes Questionnaire (MHQ) is a widely used instrument to evaluate treatment results for hand conditions. Establishing the Minimally Important Change (MIC) is essential for interpreting change in outcome that is clinically relevant.
The purpose of this study was to determine the MIC of the MHQ total and subscale scores in patients undergoing trigger finger release.
This is a prospective cohort study conducted between December 2011 and February 2020.
Patients completed the MHQ prior to surgery and 3 months postoperatively. The MIC of the MHQ was determined using 5 anchor-based methods (ie, 2 anchor mean change methods and 3 receiver operating characteristic methods). The median MIC value was determined to represent the triangulated MIC.
A total of 1814 patients were included. The MIC for the MHQ total score ranged from 7.7 to 10.9, with a triangulated estimate of 9.3. The MIC estimates for 5 of 6 of the MHQ subscales ranged from 7.7 to 20.0. No MICs could be determined for the MHQ subscale "aesthetics" due to low correlations between the anchor questions and MHQ change scores.
These MIC estimates can contribute to the interpretation of clinical outcomes following trigger finger release and for assessment of power in prospective trials.
密歇根手部结果问卷（MHQ）是一种广泛用于评估手部疾病治疗结果的工具。确定最小临床重要变化（MIC）对于解释具有临床意义的结果变化至关重要。
本研究旨在确定接受扳机指松解术的患者的 MHQ 总分和子量表评分的 MIC。
这是一项前瞻性队列研究，于 2011 年 12 月至 2020 年 2 月进行。
患者在手术前和术后 3 个月完成 MHQ。使用 5 种基于锚定的方法（即 2 种锚定平均变化方法和 3 种接收者操作特征方法）确定 MHQ 的 MIC。中位数 MIC 值用于表示三角 MIC。
共纳入 1814 例患者。MHQ 总分的 MIC 值范围为 7.7 至 10.9，三角估计值为 9.3。MHQ 子量表中的 5 个子量表中的 5 个子量表的 MIC 估计值范围为 7.7 至 20.0。由于锚定问题和 MHQ 变化得分之间的相关性较低，无法确定 MHQ 子量表“美学”的 MIC。
这些 MIC 估计值有助于解释扳机指松解术后的临床结果，并为前瞻性试验中的效力评估提供参考。
