Spirometry Monitoring and Asthma Responsibility in Kids (SMARt-Kids): A Mixed-Methods Study.
Aymee Steidl, Jenna McHale, Stephen Harmon and 1 others
PMID 42517830WHAT IT FOUND
Home spirometry felt manageable to 11 parent-child dyads, but results were hard to interpret and device and app usability was marginal.
Parents mostly ran it, while children saw it as a parent task. Parents wanted clearer explanations and child-friendly interfaces.
Key findings
01Both parents and children reported similarly high feasibility of home spirometry (parent mean 15.6, child mean 15.6; p = 0.856).
02Parents reported significantly higher acceptability than children (parent mean 15.4, child mean 12.6; p = 0.041).
03Both groups rated usability as marginal (parent mean 59.5, child mean 63.2), and qualitative themes described difficulty interpreting results, device and app problems, and parent-led shared management.

What it does not show
Only 11 dyads were studied, and they came from a prior study, so quantitative comparisons have little power and may not apply to other families. The study asked about past home use after a prior study, not whether asthma outcomes improved. The sample was broadly representative of the greater Seattle population but not of children with asthma across the United States. Some measures were not validated for children as young as seven years, which may have affected comprehension. Recruitment was from families who agreed to future contact, so families who did not engage may be underrepresented.
The easy way to misread this
Do not conclude that home spirometry and its app improve asthma control. The study described feasibility, acceptability, and usability in 11 dyads and did not test clinical outcomes.
