BACKGROUND: Hidradenitis suppurativa (HS) is a debilitating dermatologic condition presenting with recurrent abscesses. While there are multiple scales to determine HS severity, none are designed for self-administration. A validated severity self-assessment tool may facilitate survey research and improve communication by allowing patients to objectively report their HS severity between clinic visits.
OBJECTIVES: The purpose of this study was to assess a self-administered HS measure.
METHODS: An HS self-assessment tool (HSSA) with 10 photographs of different Hurley stages was developed. The tool was administered to patients diagnosed with HS who visited the Wake Forest Baptist Health dermatology clinic over a span of 2 months. Physician-administered Hurley stage was recorded to determine criterion validity. To assess test-retest reliability of the measure, patients completed the HSSA again at least 30 minutes after the first completion.
RESULTS: Twenty-four patients completed the measure, and 20 of these patients completed it twice. Agreement between physician-determined Hurley stage and self-determined Hurley stage was 66.7% with a weighted kappa of 0.57 (95% confidence interval [CI]: 0.30-0.84). The weighted kappa for agreement between patients' initial and second completion of the HSSA was 0.81 (95% CI: 0.64-0.99).
CONCLUSIONS: The self-administered measure provides moderate agreement with physician-determined Hurley stage and good test-retest reliability.
