Clinical Trial Summary

The overall goal of this project is to demonstrate the feasibility, implementation, and preliminary efficacy of a technology-assisted stepped care (TASC) adherence-promotion intervention in adolescents with asthma. Preliminary efficacy will be demonstrated by improved adherence to daily inhaled corticosteroids as measured by Propeller Health electronic monitoring devices. The TASC intervention will result in improved disease severity measured by the Composite Asthma Severity Index (combining dose of asthma medication required, asthma symptom burden, and frequency of exacerbations and health care utilization) and lung function as measured by mobile spirometry. The TASC adherence-promotion intervention implementation will be successful as evidenced by high levels of feasibility (e.g., attendance), acceptability (20 item Acceptability Questionnaire), and usability (10 item Usability Scale).

Description:

Up to thirty adolescents with asthma will be enrolled in an open label pilot trial of the TASC adherence-promotion intervention for a duration of five months. First, participants will complete baseline questionnaires related to demographic, and clinical predictors of adherence and asthma and a 4 week run-in phase to assess baseline adherence using electronic inhaler monitoring with a cellphone that is provided to them. Following the run-in period, all participants will receive Step 1 of the TASC intervention for a minimum of 4 weeks. Step 1 (Information) will include electronic educational information related to asthma symptoms and triggers, attacks, self-monitoring, treatments, action plans, and automated text message medication reminders. Following the initial four weeks of Step 1, adherence will be evaluated and a rate of less than 68% will serve as the cause for "stepping up" to the next level of the intervention. Adherence checks will continue to occur every four weeks for the duration of the study and adherence <68% will prompt movement from one level of treatment to the next. Participants may remain at a treatment level for more than four weeks and may complete 1, 2, or 3 interventions steps during the 5 month study depending on the adolescent's adherence. Step 2 (Motivation) will include electronic monitoring of adherence and personally tailored feedback via text messages. Adolescents will be given access to the adherence tracking smartphone app and graphs of their inhaler adherence. Adolescents will also receive brief, personalized text messages that provide supportive motivation and directive, tangible actions. Step 3 (Behavioral) will include problem-solving telehealth intervention with a trained clinician. Four telehealth sessions individually tailored to the unique needs and barriers of the adolescent will be provided. The primary outcome measure will be electronically-monitored adherence assessed at post-treatment. Secondary outcomes include asthma severity as well as process evaluation questions and quantitative measures of feasibility, acceptability, and satisfaction to demonstrate implementation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Electronic Monitoring	The Propeller Health monitoring system includes a Bluetooth enabled sensor that attaches to the patient's inhaler. This sensor records every dose, or "puff", the patient takes and sends it to a corresponding online database that is accessible to study staff. Participants will be given this sensor at baseline.	5 Months
Secondary	Composite Asthma Severity Index (CASI)	The participants' composite asthma severity index score will be calculated through the TreatSmart program. TreatSmart will be used to determine the participant's symptom burden, health care utilization, systemic corticosteroid use, and current medication use to determine the level of asthma severity/control the participant has. The program also makes an initial treatment recommendation based on the National Asthma Education and Prevention Program (NAEPP asthma guidelines). Individuals are placed in Step 1 through Step 6 depending on the strength and frequency of their inhaled corticosteroid (1 being low dose and 6 being a high dose). In addition, individuals are categorized as very poorly controlled, not well controlled, or well controlled based on how frequently they have had asthma symptoms or used their rescue inhaler, gone to the hospital or urgent care, or received steroids for asthma symptoms.	Baseline assessment and then once a month for 5 months
Secondary	Asthma Control Test (ACT)	The ACT will be used as a measure of disease severity in this study. The ACT is a 5-question scoring tool designed for patients with asthma who are 12 years and older. The questions ask the patient to rate their asthma severity, symptom frequency, control, and inhaler use on a scale of 1-5. The total score is calculated by the sum of each response, which determines how well-controlled the patient's asthma is on a scale from 5-25.	Baseline assessment and then once a month for 5 months
Secondary	Attendance/Participation rates	Participation rates will be measured 3 different ways. The first measure will be how often participants accessed the electronic material (educational materials and/or Propeller Health app), the second measure will be how many responses to directive text messaging were received, and the third measure will be attendance to the telehealth sessions.	5 months
Secondary	Feasibility/Acceptability Questionnaire	A 5-31 item measure of format, content, length, skills and acceptability of the intervention will be given to participants in the form of a questionnaire at the end of each step and the end of the study. The feasibility section is on a scale of 0 to 4, 0 being the worst and 4 being the best. The acceptability questionnaire is on a scale from 'Not at all' to 'Very,' 'Not at all' being the worst and 'Very' being the best.	5 months
Secondary	System Usability Scale	A 10 item, Likert scale giving a global view of usability will be given to participants in the form of a questionnaire at the end of each step and at the end of the study. The scale ranges from 'Strongly Disagree' to 'Strongly Agree, with half of the items reverse scored.	5 months
Secondary	Treatment Fidelity	Treatment fidelity needed for the intervention will be assessed. Treatment fidelity will be assessed through fidelity checklists created specifically for each intervention session.	5 months
Secondary	Time Needed for Intervention	Sessions will be timed and the number of weeks to complete the session will be tracked to determine the average length of time needed for the intervention.	5 months
