Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that severely impairs patients' quality of life (QoL). Instruments such as the 10-item Dermatology Life Quality Index and 16-item Skindex-16 have been used to assess QoL in HS; however, it is unknown whether the shorter 3-item Skindex-mini can also provide an accurate assessment of skin-related QoL in patients with HS.
The aim was to assess how well the Skindex-16 correlates with its shorter adaptation, the Skindex-mini, in capturing QoL among patients with HS.
This retrospective cross-sectional study included all HS patients seen in the HS Clinic at The Emory Clinic between January 1, 2019, and August 16, 2019. We compared the correlation between the symptom, emotion, and function domains of the Skindex-16 and Skindex-mini using Pearson correlation coefficients (CC). Secondary outcome measures included individual survey item analysis, ItchyQuant scores, and numeric rating scale of pain.
We identified 108 encounters among 75 unique hidradenitis suppurativa patients (43 black/African American, 18 white, 5 Asian/Pacific Islander, 3 Latino, 4 Other, 2 unknown). Pearson CC between the Skindex-16 and Skindex-mini domain scores for all encounters were 0.770 ( < .001), 0.787 ( < .001), and 0.801 ( < .001) for the symptom, emotion, and function domains, respectively. The mean pain and ItchyQuant scores were 4.14 (SD 3.31) and 3.55 (SD 3.34), respectively.
The Skindex-mini correlated highly with the Skindex-16 in a racially diverse group of patients with HS. The Skindex-mini is a streamlined QoL instrument that could be practically implemented into routine clinical care among diverse patients presenting to dermatology.
化脓性汗腺炎（HS）是一种慢性炎症性皮肤病，严重影响患者的生活质量（QoL）。皮肤病生活质量指数（Dermatology Life Quality Index）和 16 项 Skindex-16 等工具已被用于评估 HS 患者的 QoL；然而，目前尚不清楚较短的 3 项 Skindex-mini 是否也能准确评估 HS 患者的皮肤相关 QoL。
评估 Skindex-16 与其较短的适应版本 Skindex-mini 在评估 HS 患者生活质量方面的相关性。
本回顾性横断面研究纳入了 2019 年 1 月 1 日至 2019 年 8 月 16 日期间在埃默里诊所 HS 诊所就诊的所有 HS 患者。我们使用 Pearson 相关系数（CC）比较了 Skindex-16 和 Skindex-mini 的症状、情绪和功能域之间的相关性。次要结局指标包括个别调查项目分析、ItchyQuant 评分和疼痛数字评分量表。
我们确定了 75 例化脓性汗腺炎患者的 108 次就诊（43 例为黑人/非裔美国人，18 例为白人，5 例为亚洲/太平洋岛民，3 例为拉丁裔，4 例为其他族裔，2 例为未知族裔）。所有就诊者的 Skindex-16 和 Skindex-mini 域评分之间的 Pearson CC 分别为 0.770（<0.001）、0.787（<0.001）和 0.801（<0.001），用于症状、情绪和功能域。平均疼痛和 ItchyQuant 评分分别为 4.14（SD 3.31）和 3.55（SD 3.34）。
在种族多样化的化脓性汗腺炎患者中，Skindex-mini 与 Skindex-16 高度相关。Skindex-mini 是一种简化的生活质量工具，可以在向皮肤科就诊的不同患者中实际实施常规临床护理。
