The chronic rhinosinusitis practice parameter.

ABSTRACT

The Allergy-Immunology Joint Task Force on Practice Parameters has published the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines for the medical management of chronic rhinosinusitis with nasal polyposis (CRSwNP). The practice parameter provides evidence-based guidelines on the use of intranasal corticosteroids (INCS) and biologics for CRSwNP, and aspirin therapy after desensitization (ATAD) for the management of aspirin-exacerbated respiratory disease (AERD). Evidence on surgery was not assessed. Overall, the guidelines suggest INCS rather than no INCS (conditional recommendation, low certainty of evidence), biologics rather than no biologics (conditional recommendation, moderate certainty of evidence), and ATAD rather than no ATAD (conditional recommendation, moderate certainty of evidence). Patient-important outcomes are compared across the various INCS delivery modalities and across the different biologics and ATAD. Specific consideration points for shared decision making with patients are detailed in the guideline. These include delivery method and small treatment effect sizes for INCS, disease burden at presentation, variability in efficacy among biologics, cost issues for biologics, and adverse effects of aspirin and risks related to desensitization for ATAD. The guidelines also identify a need for randomized control trials directly comparing treatment modalities and further investigation into which outcomes are important for patients.
