The aim of this study was to construct and validate a simple patient-related outcome score to quantify the disability caused by Dupuytren's disease (DD), thus enabling prioritisation of treatment, to allow reliable audit of surgical outcome and to support future research. The Southampton Dupuytren's Scoring System (SDSS) was developed in a staged fashion according to the recommendations of The Derby Outcomes Conference. (1) Item generation; (2) Item reduction; (3) Internal consistency; (4) Test-re-test; (5) Field management; (6) Sensitivity to change standardised response mean; and (7) Criterion validity: ability of the SDSS to measure what it is supposed to measure. Internal consistency measured with Cronbach's alpha indicated acceptable reliability. The test-re-test correlation coefficient showed high reliability with SDSS. Field-testing showed SDSS ratings to be higher than the QuickDASH (Disability of the arm, shoulder and hand) ratings evaluated by the patients who answered both questionnaires. Standardised response mean was more sensitive for SDSS compared with QuickDASH showing sensitivity to change. Criterion validity was used to assess if the SDSS was measuring what it is supposed to measure comparing the SDSS with QuickDASH. A highly significant correlation was found between the two scoring systems. SDSS is a disease-specific patient-related outcome measure with a good internal consistency and performs better than QuickDASH in terms of test-re-test reliability and sensitivity to change. SDSS shows better field-testing attributes suggesting that it is a relatively more patient and practitioner friendly scoring system. This study proposes to the SDSS is a useful patient-related outcome measure for DD.
本研究的目的是构建并验证一个简单的患者相关结局评分系统，以量化由杜普伊特伦挛缩症（DD）导致的残疾程度，从而实现治疗的优先级排序，以便对手术结果进行可靠的评估，并为未来的研究提供支持。南安普敦杜普伊特伦挛缩症评分系统（SDSS）是根据德比结果会议的建议分阶段开发的。（1）条目生成；（2）条目缩减；（3）内部一致性；（4）重测；（5）现场管理；（6）对变化的敏感性——标准化反应均值；以及（7）效标效度：SDSS测量其预期测量内容的能力。用克朗巴哈α系数测量的内部一致性表明可靠性可接受。重测相关系数显示SDSS具有高可靠性。现场测试表明，SDSS评分高于同时回答两份问卷的患者所评估的QuickDASH（手臂、肩部和手部残疾）评分。与QuickDASH相比，SDSS的标准化反应均值对变化更敏感。使用效标效度通过将SDSS与QuickDASH进行比较来评估SDSS是否在测量其预期测量的内容。在两个评分系统之间发现了高度显著的相关性。SDSS是一种针对特定疾病的患者相关结局测量方法，具有良好的内部一致性，并且在重测可靠性和对变化的敏感性方面比QuickDASH表现更好。SDSS显示出更好的现场测试属性，表明它是一个相对更受患者和医生欢迎的评分系统。本研究表明SDSS是一种用于DD的有用的患者相关结局测量方法。
