BACKGROUND: Poor adherence contributes to uncontrolled asthma. Pragmatic adherence interventions for primary care settings are lacking. OBJECTIVE: To test the effectiveness of 2 brief general practitioner (GP)-delivered interventions for improving adherence and asthma control. METHODS: In a 6-month cluster randomized 2 × 2 factorial controlled trial, with GP as unit of cluster, we compared inhaler reminders and feedback (IRF) and/or personalized adherence discussions (PADs) with active usual care alone; all GPs received action plan and inhaler technique training. GPs enrolled patients prescribed combination controller inhalers, with suboptimal Asthma Control Test (ACT) scores (ACT score ≤19)..
