Safer Food Allergy Management for Adolescents

22 mars 2021 uppdaterad av: University of Pennsylvania
Among the 15 million people with food allergies in the U.S., adolescents experience the highest risk of adverse events. Yet, there are few evidence-based strategies to improve food allergy management in adolescents. In a cohort multiple randomized controlled trial, this study will include two experiments to test the effectiveness of text message reminders and incentives to encourage epinephrine-carrying.

Studieöversikt

Detaljerad beskrivning

Among the 15 million people with food allergies in the United States, adolescents experience the highest risk of adverse events, including death from anaphylaxis. Visits to one pediatric emergency department for anaphylaxis doubled between 2001 and 2006, suggesting a rapidly escalating public health burden. Despite this critical concern, there are few evidence-based strategies to improve food allergy management in adolescents, who must sustain three core prevention strategies: diligent avoidance of allergenic foods, consistent carrying of potentially life-saving epinephrine auto-injectors, and prompt administration of epinephrine in the event of anaphylaxis.

The objective of this study is to develop and test interventions to encourage safer food allergy management among adolescents. The primary outcome is consistency of epinephrine-carrying, measured using cell phone photographs at randomly-timed check-ins. This study will be among the first to longitudinally track normative food allergy management practices and one of the first to test behavior change strategies.

In a cohort multiple randomized controlled trial (n=130), the study will include two experiments to test the effectiveness of text message reminders and incentives, using various incentive designs that have proven effective in prior behavioral economics interventions to encourage weight loss and smoking cessation. Aim 1. Test the impact of a text-message reminder system on consistency of epinephrine carrying. Aim 2. Test the impact of modest incentives on consistency of epinephrine carrying. Based on promising preliminary data, the central hypothesis is that, compared to controls, adolescents who receive text message reminders plus modest financial incentives will more consistently carry their epinephrine.

Vapen och interventioner

Deltagargrupp / Arm
Intervention / Behandling
Experimentell: Intervention 1
Text Message Only
The intervention group (n=25, randomly selected from the base cohort) will receive informational and socially supportive text messages during a 10-week intervention. Investigators will deploy the intervention using the Way to Health platform, which automates outgoing messages and feedback. Many of the messages will be sent to all Intervention 1 participants, to assure consistency of the intervention. A subset will be tailored to address participants' specific allergies. At 10 unannounced check-ins, we will send text messages asking participants in the intervention and control groups if they are carrying their epinephrine.
Experimentell: Intervention 2, Incentive
Text message + Incentive
Among base cohort members not exposed to the text message only intervention (#1), we will randomly select a new intervention group (n=50) to receive text message reminders plus Incentive 1. At each of 10 unannounced check-ins, if unsuccessful in documenting epinephrine-carrying, participants will lose part of their incentive. The remainder of the Cohort (control) will receive text reminders.
Inget ingripande: Cohort
For the cohort multiple randomized controlled trial (cmRCT), investigators will recruit 130 participants (the base cohort) ages 15-19. The base cohort allows investigators to measure normative food allergy self-management practices, while also serving as a control for experiments in Interventions 1 and 2.
Inget ingripande: Control
The baseline cohort serves as the control group in this cmRCT. Participants will not receive text message reminders (during Intervention 1) or incentives (during Intervention 2). However, they will participate in all data collection points, including text message check-ins to assess epinephrine-carrying. Participants in the base cohort will receive usual care.
Inget ingripande: Adolescent Allergy Advisors
We will pilot the text messages to be used in Interventions 1 and 2 through interviews and cognitive testing among 20 Adolescent Allergy Advisors, who will critique message content, framing, and language. These advisors will not be part of the cohort multiple randomized controlled trial.
