Abstract
Objective
To evaluate the feasibility, acceptability, and usability of a real-time feedback smart inhaler for adolescents with intellectual and developmental disabilities (IDD) and asthma; assess preliminary efficacy in improving metered-dose inhaler (MDI) technique; and explore device-measured proficiency and lung function in the full cohort, alongside a predefined autism subgroup analysis.
Methods
We conducted a single-center, single-blind, pilot randomized controlled trial involving 28 adolescents (aged 10–17 years) with IDD and asthma. Participants were randomized 1:1 to an intervention group using smart inhalers with audiovisual feedback for 8 weeks, or a control group receiving standard asthma education. Primary outcomes were parent- and adolescent-reported feasibility, acceptability, and usability. The secondary outcome was observer-rated inhaler proficiency. Exploratory outcomes were full-cohort device-measured inhaler proficiency and lung function (FEV1 and PEF), alongside a predefined autism subgroup analysis.
Results
The intervention was feasible, acceptable, and usable, yielding high parent and adolescent motivation and satisfaction. The intervention group demonstrated significantly greater improvement in observer-rated Inhaler Proficiency Scale scores from baseline to week 8 compared to the control group (mean difference 1.5 points; 95% CI: 0.4–2.6; P = .02). Exploratory outcomes showed no significant between-group differences in lung function or device-measured proficiency. However, the autism subgroup exhibited inhaler technique improvements consistent with the broader cohort.
Conclusions
Smart inhalers are feasible, acceptable, and usable for adolescents with IDD, and are associated with significant improvement in observer-rated inhaler technique when combined with standard clinical education. Given the inherent challenges of spirometry in this population, future studies should incorporate effort-independent clinical assessment measures.
期刊介绍:
Academic Pediatrics, the official journal of the Academic Pediatric Association, is a peer-reviewed publication whose purpose is to strengthen the research and educational base of academic general pediatrics. The journal provides leadership in pediatric education, research, patient care and advocacy. Content areas include pediatric education, emergency medicine, injury, abuse, behavioral pediatrics, holistic medicine, child health services and health policy,and the environment. The journal provides an active forum for the presentation of pediatric educational research in diverse settings, involving medical students, residents, fellows, and practicing professionals. The journal also emphasizes important research relating to the quality of child health care, health care policy, and the organization of child health services. It also includes systematic reviews of primary care interventions and important methodologic papers to aid research in child health and education.
