Brief Summary

Background: While effective treatments are available, asthma control is sub-optimal for many asthma patients. To help patients self-manage their asthma symptoms, provision of an asthma action plan (AAP) in written format (wAAP), with instructions on managing worsening asthma symptoms is recommended, as a standard of care; however, only about half of patients correctly adhere to their AAP. Canadian Asthma Text Messaging Study (CANATEXTS) is a Telehealth (TH) intervention facilitating access to an electronic AAP (eAAP) via a mobile device. In a feasibility study to assess the safety and efficacy of CANATEXTS, an 18% reduction in the relative risk of exacerbation was observed among the intervention group compared to control group. This study will assess the effectiveness of CANATEXTS on asthma outcomes in a Canada-wide study. Methods: This is a superiority a 2-arm, multi-site randomized control trial (RCT). This study aims to determine if CANATEXTS reduces asthma exacerbation over a 12-month period, improves asthma control, quality of life (QoL) and medication adherence, and is cost-effective. The intervention includes access to an electronic asthma action plan (eAAP) on patients' mobile devices, disease-related education, and weekly reminders via a Short messaging system (SMS) interface. The study will include 620 adult participants with asthma recruited from 14 respiratory clinics across Canada. Participants will be randomly assigned to either Intervention group (eAAP) or Control groups (wAAP). All outcomes of interest will be assessed during three in-person assessments (baseline, 6-month, and 12-month) and two telephone follow-ups (3-month and 9-month). Data will be analyzed with a linear mixed-effects model across all time points. Discussion: TH has the potential to improve adult individuals with asthma's engagement in self-management practices. Our feasibility study showed TH could yield a reduction in asthma exacerbation. If the proposed TH intervention is found to be effective for asthma management in a nation-wide trial, it will generate evidence to support integration of TH in asthma self-management. This study will also provide important information on the cost-effectiveness of CANATEXTS when compared to standard asthma care.

Outcome Measures

Primary Outcomes (1)

  • Exacerbation

    An asthma attack that requires either taking a course of Oral Corticosteroids (OCS) for at least three days, or an asthma-related emergency room (ED) visit or hospitalization

    Every 6 months up to one year

Secondary Outcomes (2)

  • Asthma control

    Every 6 months up to one year

  • Medication adherence

    every 6 months up to one year

Other Outcomes (1)

  • Cost effectiveness

    at the end of year 3 through year four of the intervention

Study Arms (2)

Intervention group

EXPERIMENTAL

Intervention group/telehealth Arm: will be provided access to their electronic asthma action plan (eAAP) via a web Uniform Resource Locator (URL), receive weekly short message service (SMS) check-ins for one year, and be able to communicate with the site's research coordinator (RC) and Certified Respiratory Educator (CRE) via an integrated and interactive (two-way) SMS feature to manage their asthma

Other: CANATEXTS

Control group

ACTIVE COMPARATOR

Control group/standard care Arm: will receive their written Asthma Action Plan (wAAP) and information on how to use it by the site's Certified Respiratory Educator to manage their asthma

Other: CANATEXTS
