Background: Cystic fibrosis (CF) caregivers focus on correct inhalation technique for nebulisers as this is essential to optimize efficacy of inhaled drugs. However, little is known on this nebuliser technique of patients at home.
Methods: Three "hidden" video registrations were made of 32 children with CF (6-18. years) nebulising at home. Videos were randomly scored on inhalation technique items using nebuliser-specific checklists and a total score was calculated.
Results: Median nebuliser technique was 91.9% of max score. Nebuliser technique was perfect (score 100%) in 23.3% of the patients and incorrect (score 0%) in 13.3%. Most mistakes were made in the required optimal breathing pattern.
Conclusion: Most CF patients had good nebuliser technique on a day-to-day basis. However, errors observed likely resulted in reduced treatment efficacy and, in 13%, no treatment at all. Regular "real life" evaluation by the CF-team can improve inhaled therapy substantially.
