Abstract

Introduction: The aim of this study was to evaluate the construct validity, floor and ceiling effects, data completeness and magnitude of change over time for the eight-item patient questionnaire (HQ-8) in the Swedish Healthcare Quality Registry for hand surgery (HAKIR).

Methods: Construct validity was investigated through predefined hypotheses and correlation statistics between the single items in HQ-8 (pain on load, pain on motion without load, pain at rest, stiffness, weakness, numbness, cold sensitivity and ability to perform daily activities) and QuickDASH. Floor and ceiling effects and data completeness were analysed at preoperative (n = 13,197), three months (n =10,702) and one year (n = 9,986) responses from hand surgery patients. Effect sizes were calculated for pre- and postoperative change scores in elective conditions and postoperative scores for acute conditions.

Results: Correlation coefficients at pre, 3 and 12 months ranged from 0.44 to 0.79 in the total group. No ceiling effect occurred, but a floor effect for the total group was noted for all items at all follow-ups. Missing responses were < 2.6% except for cold sensitivity. The effect sizes varied from small to large for individual items in elective diagnoses. For acute injuries, small effect sizes were found.

Discussion: This study provides evidence of construct validity of HQ-8, lack of ceiling effect, expected floor effect, good data completeness and an ability to detect changes over time. The results indicate that HQ-8 measures unique aspects of disability. The HQ-8 could complement the Quick-DASH in describing patient-reported outcomes after hand surgery.

八项HAKIR问卷的结构有效性、下限和上限效应、数据完整性和变化幅度:瑞典国家医疗保健质量注册中心手部手术患者报告的结果。
引言:本研究的目的是评估结构的有效性、地板和天花板效应,瑞典手外科医疗质量注册中心(HAKIR)的八项患者问卷(HQ-8)的数据完整性和随时间变化的幅度。方法:通过预先定义的假设和HQ-8中单个项目之间的相关性统计来调查结构有效性(负荷时疼痛、无负荷运动时疼痛、休息时疼痛、僵硬、虚弱、麻木、对寒冷敏感以及进行日常活动的能力)和QuickDASH。术前(n = 13197),三个 月(n=10702)和1 年(n = 9986)来自手外科患者的反应。计算选择性条件下的术前和术后变化评分以及急性条件下的手术后评分的影响大小。结果:pre、3和12的相关系数 总组的月数在0.44至0.79之间。没有出现上限效应,但在所有随访中,所有项目都出现了总组的下限效应。缺少的回复为 讨论:本研究提供了HQ-8的结构有效性、缺乏上限效应、预期下限效应、良好的数据完整性和检测随时间变化的能力的证据。结果表明,HQ-8测量残疾的独特方面。HQ-8可以在描述患者报告的手部手术后的结果方面补充Quick DASH。
