Trial Outcomes & Findings for The Study is Enrolling Kids From 8 to 17 Years Old. The BreathSmart Device Attaches to the Inhaler to Measure Adherence. (NCT NCT03734861)

NCT ID: NCT03734861

Last Updated: 2023-04-07

Results Overview

Medication adherence among children using BreatheSmart with feedback (intervention) compared to control group (standard of care) at 6 months. The primary outcome was medication adherence as measured using pharmacy refill. Medication adherence as measured by pharmacy refills was calculated using proportion of days covered (PDC), a validated method of calculating adherence, defined as a ratio of the sum of unique days supplied based on refills over the total number of days in the assessed period.

PRIMARY outcome

Timeframe: 6 months post start of intervention

Population: Participants in the BreatheSmart arm (intervention) received the EMD, app, and reminder notifications. Participants in the control group continued to receive routine clinical care. They were reminded to adhere to prescribed therapy during their clinical encounters

SECONDARY outcome

Timeframe: 6 months post start of intervention

Population: Participants in the intervention group received an electronic monitoring device (Herotracker), which is synced to the BreathSmart mobile app, designed to send reminder notifications to participants, and are able to collect medication adherence data. Participants are able to track and review their medication adherence using the app. Participants in the control group continued to receive routine clinical care. They were reminded to adhere to prescribed therapy during their clinical encounters.

The Asthma control Test (ACT) assess a patient's level of asthma control based on responses to 5 symptom-related questions over the past 4 weeks. Respondents must select a number on a 5-point likert scale (1-5) for each item. The response to each question is summed, ranging from 5-25. Scores of 19 or less indicate poorly controlled asthma. Higher scores mean better asthma control.

SECONDARY outcome

Timeframe: Baseline to 6 months post start of intervention

Population: The analysis population was comprised of children enrolled in either the control (standard of care) arm or the intervention (Breathesmart, HeroTracker) arm.

The correlation between changes in medication adherence and changes in FEV1 percent predicted. FEV1 is forced expiratory volume in 1 second is the maximum amount of air that a subject can forcibly expel during the first second following maximal inhalation. FEV1 can be useful to categorize the severity of asthma. Expressing FEV1 as a percentage of the predicted value in a patient is means by which to express this severity.
