Phase II trial of web-based tailored asthma management intervention in adolescents at clinics

Telehealth interventions for transition to self-management in adolescents with allergic conditions: A systematic review

Telehealth is an emerging approach that uses technology to provide healthcare remotely. Recent publications have outlined the importance of supporting the transition to self-management of adolescents with allergic conditions. However, no synthesis of the evidence base on the use and impact of telehealth interventions for this purpose has been conducted to date. This review achieves these aims, in addition to exploring the language use surrounding these interventions, and their implementation. Four databases were searched systematically. References were independently screened by two reviewers. Methodological quality was assessed using the Mixed Methods Appraisal Tool. A narrative synthesis was undertaken. Eighteen articles were included, reporting on 15 telehealth interventions. A total of 86% targeted adolescents with asthma. Mobile applications were the most common telehealth modality used, followed by video-conferencing, web-based, virtual reality and artificial intelligence. Five intervention content categories were identified; educational, monitoring, behavioural, psychosocial and healthcare navigational. Peer and/or healthcare professional interaction, gamification and tailoring may increase engagement. The studies showed positive effects of the interventions or no difference from active controls, in self-management outcomes such as knowledge, health outcomes such as quality-of-life, and economic outcomes such as healthcare utilization. The most common implementation outcomes reported were acceptability, appropriateness, feasibility and fidelity.

Participant-level characteristics differ by recruitment setting when evaluating a behavioral intervention targeting adolescents with asthma

OBJECTIVE

The recruitment setting plays a key role in the evaluation of behavioral interventions. We evaluated a behavioral intervention for urban adolescents with asthma in three randomized trials conducted separately in three different settings over the course of 8 years. We hypothesized that characteristics of trial participants recruited from the ED and clinic settings would be significantly different from that of youth participating in the school-based trials. The intervention evaluated was Puff City, a web-based program that uses tailoring to improve asthma management behaviors.

METHODS

The present analysis includes youth aged 13-19 years who reported a physician diagnosis of asthma and symptoms at trial baseline. In the three trials, all participants were randomized post-baseline to a web-based, tailored intervention (treatment) or generic web-based asthma education (control).

RESULTS

Compared to school-based trial participants, ED participants had significantly more acute-care visits for asthma (p < 0.001) and more caregiver depression (p < 0.001). Clinic-based participants were more likely to have computer/ internet access than participants from the school-based trial (p < 0.001). Both ED and clinic participants were more likely to report controller medication (p's < 0.001) and higher teen emotional support (p's < 0.01) when compared to the schools, but were less likely to report Medicaid (p's < 0.014) and exposure to environmental tobacco smoke (p < 0.001).

CONCLUSION

Compared to participants in the school-based trials, participants recruited from ED and clinic settings differed significantly in terms of healthcare use, as well as psychosocial and sociodemographic factors. These factors can inform intervention content, and may impact external validity of behavioral interventions for asthma.
