Design outcomes

Primary

MeasureTime frameDescription
International Hidradenitis Suppurativa Severity Score System (IHS4)Baseline and follow-up visits every 6-12 months for up to 5 years.Clinician-assessed measure of hidradenitis suppurativa severity based on the number of inflammatory nodules, abscesses, and draining tunnels; higher scores indicate more severe disease.

Secondary

MeasureTime frameDescription
Hurley Staging SystemBaseline and follow-up visits every 6-12 months for up to 5 years.Clinician-assessed classification of hidradenitis suppurativa severity categorized as Stage I, Stage II, or Stage III.
Sartorius Hidradenitis Suppurativa Severity Score (HSS)Baseline and follow-up visits every 6-12 months for up to 5 years.Clinician-assessed measure of hidradenitis suppurativa severity incorporating lesion counts and anatomical involvement; higher scores indicate more severe disease.
Physician Global Assessment (PGA)Baseline and follow-up visits every 6-12 months for up to 5 years.Clinician-assessed global measure of hidradenitis suppurativa severity on a scale from 0 to 4, with higher scores indicating more severe disease.
Dermatology Life Quality Index (DLQI)Baseline and follow-up visits every 6-12 months for up to 5 years.Patient-reported measure of dermatology-specific quality of life; total score ranges from 0 to 30, with higher scores indicating greater impairment.
Patient-reported Numerical Rating Scale (NRS) for severity of hidradenitis suppurativaBaseline and follow-up visits every 6-12 months for up to 5 years.Patient-reported assessment of overall hidradenitis suppurativa severity on a numerical rating scale from 0 (no disease) to 10 (most severe disease imaginable).
Patient-reported Numerical Rating Scale (NRS) for pain related to hidradenitis suppurativaBaseline and follow-up visits every 6-12 months for up to 5 years.Patient-reported assessment of hidradenitis suppurativa-related pain on a numerical rating scale from 0 (no pain) to 10 (worst imaginable pain).
