• Study description:
  The results of real-life respiratory studies often meet with challenges from peer reviewers who are unfamiliar with the described methods. Particularly problematic are real-life outcomes that refer to “asthma control,” as they differ from the traditional, validated clinical tools. Reviewers often challenge the endpoints, and composite endpoints, used in database studies in terms of their validity – are they truly are accurate reflections of the clinical reality they are attempting to measure. Usually these concerns implicitly assume (that the gold standard in outcome assessment are the measures used in prospective randomized controlled trial (RCTs), and thus request information regarding the association between real-life outcome assessments and RCT-used tools. The aim of this study is to validate a series of objective asthma control measures that have been used in published real-life respiratory research. The outcome measures will be compared to patient-reported outcomes and/or to validated RCT asthma measures (as appropriate). Where possible, their validity, responsiveness and predictive value will also be assessed and a rank order of outcomes (and possibly hierarchical modelling) will be established to aid in appropriate outcome selection for future database studies.
