An international Delphi exercise appears to be useful in attaining expert consensus opinion regarding the items needed to identify disease activity in cases of large vessel vasculitis and will influence future development of large vessel vasculitis outcome measures, according to recently published findings.
Researchers conducted an international Delphi exercise to determine factors considered to be important in identifying active disease status in large vessel vasculitis (LVV) in clinical trials. Researchers identified 317 LVV experts who were involved in clinical research in vasculitis and/or attended academic vasculitis meetings, and sent the Delphi survey to these experts by email. Researchers placed special emphasis on the inclusion of diverse geographic areas and medical specialties. When considering multiple proposed items in the survey, respondents were asked, “Should the following item be used to assess disease activity in Takayasu arteritis (TA)/giant cell arteritis (GCA)in clinical trials?” Voting on these items was conducted separately for GCA and TA.
