Takeaway

  • The Severity and Area Score for Hidradenitis (SASH), based on body surface area (BSA) affected, is a reliable and valid outcome measurement tool for patients with hidradenitis suppurativa (HS).

Why this matters

  • This new tool addresses the need for a reliable and consistent outcome measurement of affected BSA in patients with HS.

Key results

  • The intraclass correlation coefficient (ICC) for intrarater reliability was 0.98 (95% CI, 0.94-1.00).
  • The ICC for interrater reliability was 0.60 (95% CI, 0.44-0.74).
  • Modified methods that analyzed BSA differently improved the ICC for interrater reliability to 0.75 (95% CI, 0.62-0.85) or 0.76 (95% CI, 0.62-0.85).
  • Correlations between SASH and other clinician-reported measures varied from 0.68 to 0.79.
    • 0.68 (95% CI, 0.60-0.75) for Hurley stage, 0.71 (95% CI, 0.63-0.77) for abscess nodule count, 0.79 (95% CI, 0.73-0.84) for modified Sartorius.

Study design

  • 10 clinicians (8 dermatologists, 2 gynecologists) contributed to concept elicitation.
  • 11 clinicians (9 dermatologists, 2 gynecologists) contributed to cognitive debriefing.
  • Evaluation included 10 clinicians and 23 patients.
  • Funding: Agency for Healthcare Research and Quality; National Center for Advancing Translational Sciences.

Limitations

  • Responsiveness of tool was not established.
  • Small number of providers and patients included.
