Asthma is managed by health professionals from different specialties. We aim to reach a consensus on the optimal use of inhaled therapy and the initial steps of asthma treatment, taking into account the opinions of the involved specialists.
A modified Delphi approach was used. A scientific committee provided 52 controversial statements, which were submitted to primary care physicians, allergists, and pulmonologists. Discrepancies among specialties were evaluated.
A total of 209 specialists completed the questionnaire (20.2 ± 9.3 years of asthma management experience). A consensus was reached on 37 statements (71.1%), discrepancies among specialties were found in 14. The most recommended maintenance treatment for mild persistent asthma in adults/adolescents was low-dose-inhaled corticosteroids daily. MART (Maintenance and Reliever Therapy) was recommended as salvage treatment for moderate persistent asthma. Panelists agreed on the most frequent critical errors with pressurized Metered-Dose Inhalers or Dry-Powder Inhalers, and considered that Breath-Actuated Inhalers are a suitable option for all patients with the ability to inhale voluntarily.
The experts endorse the main guidelines recommendations; however, do not fully agree on recent GINA recommendations about the treatment of the initial steps of the disease. The experts value positively the differential characteristics of BAI over other devices.
