Disease Modification in Asthma: Are We on the Right Way? A Multidisciplinary Expert Delphi Consensus (MODIASTHMA Consensus).

Purpose: With the advent of biological therapies, emerging concepts regarding establishing new targets in asthma management, such as disease modification, have entered the debate among the scientific community. The definitions that form the conceptual basis of this goal need to be agreed upon.

Methods: A multidisciplinary expert group was assembled as the steering committee. A systematic literature review was conducted to identify the scientific background for constructing appropriate definitions. Based on the literature review and the clinical experience of the experts, the committee built a list of statements that could be applied to establish the definition of disease modification in asthma. After that, a Delphi validation was performed to assess the appropriateness of the list of statements. The questionnaire included a total of 22 statements, divided into "Essential criteria for disease modification in asthma" (5 statements) and "Disease modification indicators and other considerations" (17 statements). Panelists used a 9-point Likert scale to measure agreement on each statement. The cut-off point for high consensus was defined as a minimum score of 7 and had to be reached by at least two-thirds of the experts.

Results: A total of 192 asthma experts voted on statements anonymously. Of those, 104 (54%) were Pneumologists, 65 (34%) were allergologists, and 23 (12%) were Pediatricians. An interim analysis of round 1 data was performed. All statements reached consensus on the first round, with a median score above 7 in all cases.

Conclusion: In conclusion, in this Delphi study, a large number of experts in the management of severe asthma from different specialties agreed on the clinical-functional and pathophysiological aspects to be considered in order to try to achieve disease modification.
