背景：患者报告的结果越来越多地被用作干预措施有效性的衡量标准。为了使这些工具更有用，已经开发了被称为最小重要差异的治疗阈值。本研究的目的是计算拇趾外翻手术的足和踝结局评分领域的最小重要差异。研究方法：该研究基于对2013年10月至2018年1月期间新安排进行拇囊炎矫正手术并完成患者报告结局的患者的回顾性分析。本研究使用基于锚和基于分布的方法计算仪器5个领域的最小重要差异。计算每种方法的置信区间。共有91名参与者参与了这项研究。结果如下：使用基于锚和基于分布的方法，疼痛领域的最小重要差异范围为5.8 - 10.2，症状领域为0.3 - 6.9，日常生活活动领域为8.3 - 10.3，生活质量领域为7.4 - 11.1，运动和娱乐领域为7.0 - 15.7。对于功能更好的患者，日常生活活动的微小差异可能在临床上更重要。讨论内容：每个领域的最小重要差值范围表明足踝结局评分与拇囊炎矫正手术的对应关系。体育和娱乐领域的价值观的范围内表现出相当大的变化，并可能与域的缺乏响应。总体而言，FAOS领域的最小重要差异值从4以上到16以下不等。
Background: Patient-reported outcomes are increasingly used as measures of effectiveness of interventions. To make the tools more useful, therapeutic thresholds known as minimally important differences have been developed. The objective of this study was to calculate minimally important differences for the domains of the Foot and Ankle Outcome Score for hallux valgus surgery. Methods: The study was based on a retrospective analysis of patients newly scheduled for bunion correction surgery and completing patient-reported outcomes between October 2013 and January 2018. This study used anchor- and distribution-based approaches to calculate the minimally important difference for the instrument's 5 domains. Confidence intervals were calculated for each approach. There were 91 participants included in the study. Results: Using anchor- and distribution-based approaches, the minimally important difference for the pain domain ranged from 5.8 to 10.2, from 0.3 to 6.9 for the symptoms domain, 8.3 to 10.3 for the activities of daily living domain, 7.4 to 11.1 for the quality of life domain, and from 7.0 to 15.7 for the sports and recreation domain. Small differences in the activities of daily living domain may be more clinically important for patients with better function. Discussion: The range of minimally important difference values for each domain indicate how the Foot and Ankle Outcome Score corresponded to bunion correction surgery. The sports and recreation domain showed considerable variability in the range of values and may be associated with the domain's lack of responsiveness. Overall, most minimally important difference values for the domains of FAOS ranged from above 4 to below 16.
