NCT06461403RECRUITINGNAThis will be a randomized, controlled, clinical trial. The investigators aim to determine the feasibility of and efficacy of the Inhaler Trainer Device for ongoing inhaler skill training. The research team will enroll 140 patients from the inpatient or outpatient setting from the University of Chicago Medicine over the course of up to 12 months. Participants will complete assessments, a lung function test via spirometry, and inhaler education via either the Inhaler Trainer Device learning program or Brief Intervention. All participants will return at 6 weeks (window of +/- one week) post-initial inhaler education for an in-person evaluation of their inhaler skills, lung function, and acute care utilization. Finally, a post-study semi-structured interview will be conducted to gather feedback on the device after the 6-week visit has been completed.
