UTI Reference Standard: Delphi Method

This study will use a modified Delphi approach, consisting of a set of iterative questionnaires. In round 1, an expert panel will grade the relevance of UTI-related items, after which a smaller core research team will compose a reference standard in a series of (online) meetings. In round 2, clinical vignettes will be used to party validate the reference standard and expert panel agreement with the new reference standard will be assessed.
