TOPLINE:

A digital, noninvasive home‑monitoring system — integrating home spirometry, smartwatch data, and medical feedback — showed promise for managing pediatric asthma. Nocturnal heart rate monitoring was associated with asthma control and may serve as a promising noninvasive marker for deterioration. 

METHODOLOGY:

• Researchers conducted a prospective study involving 38 children with asthma (median age, 9 years; 68.4% boys) to evaluate whether real-time digital monitoring at home could detect early signs of disease deterioration and improve asthma control.
• Children were monitored for 12 weeks using a certified healthcare platform, a wrist-worn wearable to monitor heart rate and activity, and a home spirometer for weekly lung function measurements.
• The healthcare platform provided educational content, measurement overviews, automated reminders, secure text-based communication with clinicians, and tailored monitoring protocols.
• Automated alerts were sent to the healthcare team when asthma was poorly controlled, or when forced expiratory volume in 1 second dropped > 10% from the reference value; the app then queried symptoms and routed families to the appropriate protocol.
• The primary endpoint was asthma control assessed via Asthma Control Test questionnaires; a score of ≤ 19 indicated poorly controlled or uncontrolled asthma.

TAKEAWAY:

• An increase in nocturnal heart rate above the age-appropriate median was significantly associated with worsening Asthma Control Test scores (odds ratio [OR], 2.11; P = .032); the association was significant even after adjusting for rescue medication use.
• More frequent home spirometry was significantly associated with worsening Asthma Control Test scores (OR, 2.94; P < .001).
• Childhood Asthma Control Test scores at baseline for children aged 6-11 years tended toward improvement after 12 weeks, but lung function measurements did not change significantly.
• Adherence to home monitoring declined over time, with wear-time compliance for the wrist-worn device falling from 80% to about 50%, indicating that sustained engagement with monitoring devices is challenging.

IN PRACTICE:

“These advances [remote alerts, optional monitoring, and minimal burden] signal a shift toward individualized, technology-driven approaches for early detection and quantitative control assessment,” the authors wrote.

SOURCE:

The study was led by Casper E.W. Gijsen, Care and Public Health Research Institute, Maastricht University, Maastricht, Netherlands. It was published online on November 11, 2025, in Scientific Reports.

LIMITATIONS:

The study was conducted over a short period during spring and summer; therefore, it may not have captured seasonal variations in asthma symptoms. It used a single-cohort design without a control group. Additionally, participation was voluntary, which likely introduced selection bias toward individuals more motivated than the general population.

DISCLOSURES:

No funding was reported for the study. The authors reported having no competing interests.
