Treatment Phenotypes for Adolescents With Asthma

This study will evaluate how adolescents take their asthma medications using an electronic medication monitor.

Study Overview

• Status: Completed
• Conditions: Asthma in Children; Adherence, Treatment
• Intervention / Treatment: Device: Medication monitoring

Detailed Description

This study will look at how adolescents use both their controller and rescue medications using an electronic medication monitoring platform, for the period of one year. Participants will be enrolled in a medication monitoring platform, and their asthma care provider will have access to medication usage information. The study team will collect data on medication use patterns in a real world setting for 12 months per participant. Additionally, healthcare providers will be enrolled in focus groups to determine barriers and facilitators to optimal medication use for their patients.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Cohort; Participants will be enrolled in medication use monitoring. Their medication use patterns will be available to themselves and their guardians via a smartphone application, and to their asthma care providers via a portal. There will be no interventions to change medication use patterns. A portion of them will be asked to participate in a semistructured interview during which they will be asked questions about their perception of their asthma, health beliefs regarding medication use, and what they feel would be the most helpful to get them to take their asthma medicines. Additionally a small group of healthcare providers will be asked to participate in a focus group to collect qualitative data on medication use barriers and facilitators

Device: Medication monitoring; This is an observational study of medication use patterns. The propeller health device has reminders for controller medication use and gives feedback regarding medication use to the participant, their guardian and their asthma provider

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Treatment Phenotypes	The Investigators will calculate the number of participants that fall into the following treatment phenotypes: "Well controlled-good adherence", "Well controlled-poor adherence", "Poorly controlled-good adherence", "Poorly controlled-poor adherence". We had initially planned to report only these 4 groups, however there was a very clear breakdown into 9 groups-as we needed to consider a moderately controlled group and a moderately adherent group. Therefore the groups are reported as follows: Poor Adhrence, Poor control Poor adherence, moderate control poor adherence, good control Moderate adherence, poor control moderate adherence, moderate control moderate adherence, good control good adherence, poor control good adherence, moderate control good adherence, good control The investigators will use group based trajectory modeling to evaluate adherence and control phenotypes	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Qualitative Information Regarding Barriers for Medication Use	Qualitative data (semistructured interviews with patients regarding barriers to medication use.	12 months
Qualitative Information Regarding Facilitators for Medication Use	Qualitative data (semistructured interviews with adolescents) regarding barriers to medication use.	12 months
Qualitative Information Regarding Facilitators for Medication Use	Qualitative data (focus groups with healthcare providers) to determine facilitators to medication use.	12 months
Qualitative Information Regarding Barriers for Medication Use	Qualitative data (focus groups with healthcare providers) to determine facilitators to medication use.	12 months
