Hidradenitis suppurativa (HS) has no agreed-upon COS. A central aspect in the COS development process is to identify a set of candidate outcome domains from a long list of items. Our long list had been developed from patient interviews, a systematic review of the literature and a healthcare professional survey, and initial votes had been cast in two e-Delphi surveys. In this manuscript, we describe two in-person consensus meetings of Delphi participants designed to ensure an inclusive approach to generation of domains from related items.<h4>Objectives</h4>To consider which items from a long list of candidate items to excludeThe British journal of dermatologyTowards global consensus on core outcomes for hidradenitis suppurativa research: an update from the HISTORIC consensus meetings I and II.PMC5935265HCRW_HF-14-08L30 AR072438HF-14-08K08 HS024585Prens EPGottlieb ABChoon SEArdon CTheut Riis PMerola JFMehdizadeh AOrgill DChristensen RDellavalle RDavis MDaham NGibbons AFilippelli MMatusiak LFernandez-Penas PGuilbault SBechara FGGrant TCohen ADPallack LRandell SRogers CGarg AHarvent CEmtestam Lvan der Zee HHOkun MParks-Miller AThorlacius LIngram JRBaba RKirby JSMojica THarris CHouston KRosen CFJemec GBEGulliver SVillumsen BfalseTowards global consensus on core outcomes for hidradenitis suppurativa research: an update from the HISTORIC consensus meetings I and II.<h4>Background</h4>A core outcomes set (COS) is an agreed minimum set of outcomes that should be measured and reported in all clinical trials for a specific condition.
