Systemic Sclerosis (SSc) patients may need hand surgery.
To develop a screening tool for rheumatologists to identify potential candidates with systemic sclerosis for hand surgery, optimizing referrals.
A pilot cross-sectional study from January 2015 to December 2016.
51 participants.
≥ 18 years old, meeting the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for SSc and hand impairment.
age, sex, race, disease duration, SSc subtypes, vasodilator use, skin thickness, finger stiffness, presence of Digital Ulcers (DU) and/or calcinosis, presence of Raynaud's Phenomenon (RP) attacks, health status and disability, disease status, pain intensity and functional status of the hands. Data were analyzed by a multivariate logistic regression model.
Fulfillment of surgical criteria: 68.8%. The surgical group had higher scores on the HAQ-DI (1.39 vs. 0.96, p = 0.032) and CHFS (25.0 vs. 12.0, p = 0.005) questionnaires, and a higher frequency of DU (91.43% vs. 18.75%, p < 0.0010), calcinosis (60.0% vs. 0.0%, p < 0.001), use of vasodilators (100.0% vs. 75.0%, p = 0.007) and digital stiffness (28.57% vs. 0.0%, p = 0.017). The presence of DU increased the chance of surgical indication by 46.2 times (ORIC 95% = 8.23 to 259.49). The statistical model showed good accuracy (86.3%, p < 0.001), sensitivity (91.4%), and specificity (81.2%).
The presence of DU in SSc could be used as a screening feature for early identification and referral of potential candidates for hand surgery.
系统性硬化症（SSc）患者可能需要手部手术。
为风湿病学家开发一种筛选工具，以识别有手部手术适应证的系统性硬化症患者，从而优化转诊。
这是一项 2015 年 1 月至 2016 年 12 月的前瞻性横断面研究。
51 名参与者。
年龄≥ 18 岁，符合 2013 年美国风湿病学会/欧洲抗风湿病联盟（ACR/EULAR）系统性硬化症分类标准，且存在手部功能障碍。
年龄、性别、种族、疾病持续时间、SSc 亚型、血管扩张剂使用情况、皮肤厚度、手指僵硬、存在指溃疡（DU）和/或钙沉积、存在雷诺现象（RP）发作、健康状况和残疾、疾病状况、手部疼痛强度和功能状态。采用多变量逻辑回归模型进行数据分析。
符合手术标准的患者占 68.8%。手术组的 HAQ-DI（1.39 比 0.96，p=0.032）和 CHFS（25.0 比 12.0，p=0.005）评分更高，且 DU（91.43%比 18.75%，p<0.0010）、钙沉积（60.0%比 0.0%，p<0.001）、血管扩张剂使用（100.0%比 75.0%，p=0.007）和手指僵硬（28.57%比 0.0%，p=0.017）的发生率更高。DU 的存在使手术指征的可能性增加了 46.2 倍（ORIC 95%CI：8.23 至 259.49）。该统计模型具有良好的准确性（86.3%，p<0.001）、敏感性（91.4%）和特异性（81.2%）。
SSc 患者存在 DU 可作为早期识别和转诊手部手术潜在候选者的筛查特征。
