Hidradenitis Suppurativa Mail Survey

Primary Outcomes (3)

• Comparison of self-assessed severity to physician-assessed severity of HS

  Participants will be administered a 2-page survey with photographs of HS in varying degrees of severity (Hidradenitis Suppurativa Self-Assessment tool, or HSSA) and asked to check the photo(s) that represent their condition now and when it was the worst it has ever been. The photos correspond with severity levels 0 (no disease), 1, 2, and 3 according to the Hurley Staging system (a commonly used system to evaluate severity of HS). Physicians will also assess the Hurley severity of disease when they see the patient. Agreement between physician severity assessment and self assessment will be measured.

• Test-retest reliability of self-assessed severity of HS

  Participants will be administered a 2-page survey with photographs of HS in varying degrees of severity and asked to check the photo(s) that represent their condition now and when it was the worst it has ever been. The photos correspond with severity levels 0 (no disease), 1, 2, and 3 according to the Hurley Staging system (a commonly used system to evaluate severity of HS). At least 30 minutes later, participant's will re-do the HSSA. Agreement between the original and second response will be assessed to establish test-retest reliability of the tool.

• Ability of HSSA to detect changes in disease severity over time

  For those patients who are recruited in person, when they come back to the clinic for follow-up, the HSSA will be administered again. The physician will also provide an assessment of severity. These will be compared to the original physician assessment and HSSA result to determine the ability of the HSSA to detect changes in disease severity over time.
