Abstract: The aim of this GA2LEN consensus report is to provide recommendations for Patient-Reported Outcomes evaluation in clinical trials for allergic diseases, which constitute a global health problem in terms of physical, psychological, economic and social impact. During the last 40 years PROs have gained large consideration and use in the scientific community, in order to gain a better understanding of patients’ subjective assessment with respect to elements concerning their health condition. They include all health-related reports coming from the patient, without involvement or interpretation by physician or others. PROs assessment should be performed by validated tools (disease-specific tools when available, or generic ones) selected taking into account the aim of the study, the expected intervention effects and the determinant and confounding factors or patient related factors which could influence PROs. Moreover, each tool should be used exclusively in the patient population following the authors’ indications without modification and performing a crosscultural validation if the tool must be used in a language that differs from the original. The result analysis also suggests that the relevance of PROs results in any interventional study should include a pre-post assessment providing information concerning statistical differences within or among groups, rates of response for the PROs outcome and a minimal important difference for the population. The report underlines the importance of further investigation on some topics, such as the quality assessment of existing PROs tools, the definition of inclusion and exclusion criteria and a more extensive evaluation of the correlation between PROs, besides HRQoL, and clinical data.
