Inter-societal Delphi Consensus on the topical nasal treatments in Italy.

Topical nasal therapy is widely used in clinical practice by different specialists. However, it is multifaceted and still controversial. Namely, there is no consensus about the many aspects, and there needs to be specific guidelines. Four independent experts involved 14 Italian scientific societies (concerning ENT, allergy, and pediatrics areas) to participate in generating an Intersocietal Delphi Consensus on this matter. Three iterative rounds collected experts (4 in the first round, 20 in the second round, and 45 in the third round) designed by the scientific societies based on their clinical expertise and documented scientific value. Thirty-four statements were discussed and voted on. At the second round, all statements accomplished a very high consensus grade (>95%). At the third round, many statements reached a high or very high grade of consensus (>70%). However, some statements did not obtain sufficient agreement. Consequently, there is a need to implement knowledge about this issue through educational initiatives and new studies conducted with a robust methodology. In conclusion, topical nasal therapy deserves adequate knowledge as it is widespread and fruitful in managing upper respiratory diseases.
