Abstract

Introduction: Suboptimal adherence to preventer therapy remains one of the main factors negatively affecting asthma control. Motivational strategies can effectively improve adherence, especially if they incorporate individual goals.

Methods: We surveyed persons with asthma to assess the importance of asthma-related goals. The survey was created based on the results of two focus groups with asthmatics. The six selected goals were related to daily activities, sleep, exercise, sensitivity to triggers, asthma symptoms and the risk of an asthma attack. Asthma control and adherence were assessed with the Asthma Control Survey (VoiceMed) and the Inhaler Adherence Questionnaire (IAQ, Toelle et al. 2020). Participants were presented with brief information about the benefits of preventer treatment and asked if an app would help them ?stay on track with asthma medication?.

Results: Of the 85 survey participants, 32 were not taking any preventer inhalers. Of the remaining participants, 50.9% were uncontrolled and non-adherent (95% CI 36.8 % - 64.9%), 34.0% uncontrolled and adherent (95% CI 21.5 % - 48.3%), 5.7% controlled and non-adherent (95% CI 1.2 % - 15.7%) and 9.4% controlled and adherent (95% CI 3.1 % - 20.7%). The proportion of participants that selected each asthma-related goal as being important to them ranged from 24.1% (95% CI 11.8 % - 41.2%) to 54.1% (95% CI 36.9 % - 70.5%). There were no statistically significant differences in the prevalence of goals between different groups and no difference in proportion between goals. Thirty-seven per cent of the uncontrolled and non-adherent group (95% CI 19.4 % - 57.6%) and 30.8% of the uncontrolled and adherent (95% CI 9.1 % - 61.4%) confirmed that an app could be helpful with preventer adherence.
