Interrater agreement and reliability of outcome measurement instruments and staging systems used in hidradenitis suppurativa.

CONCLUSION: The very wide intervals for limits of agreement imply that substantial changes are needed in clinical research in order to rule out measurement error. The results illustrate a difficulty, even for experienced HS-experts, to agree on the type and number of lesions when evaluating disease severity. The apparent caveats call for global efforts, such as the HIdradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) to reach consensus on how valid HS physical signs are best measured reliably in randomised trials.
