Spanish Consensus on the Management of Chronic Rhinosinusitis With Nasal Polyps (POLIposis NAsal/POLINA 2.0).

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a highly prevalent and burdensome disease for both individuals and health systems. Its management involves many specialties, including otorhinolaryngology, allergology, pulmonology, primary care, pharmacy, and pediatrics. A multidisciplinary approach and the participation of the patient in decision-making are essential, both for diagnosis and for therapy. The authors of the consensus aim to translate current knowledge into an easy-to-read practical guide and emphasize those aspects requiring further discussion or with unmet needs owing to the lack of appropriate scientific evidence. An iterative approach for the development of an evidence-based systematic review with recommendations was followed using a standard quality assessment approach (Scottish Intercollegiate Guidelines Network [SIGN] and National Institute for Health and Care Excellence [NICE]). The guideline was critically evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE II) and Recommendation Excellence (AGREE REX) instruments. Consequently, POLINA has been considered a high-quality guideline by an independent agency. The POLINA consensus provides new definitions of control, therapeutic management (including surgery and evaluation of severity), indications for use of biologics, and response. Finally, this guideline focuses on unmet research needs in CRSwNP.
