Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested a digital tool called iREACH that helps pediatricians follow national guidelines for introducing peanuts to infants. The tool provides reminders and education during checkups at 4, 6, 9, and 12 months. Researchers measured how well doctors followed the guidelines and tracked peanut allergy rates in 30 infants up to age 2.5 years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
iREACH Clinical Decision Support tool (educational module and EHR prompts)
What this could lead to
If successful, this tool could help doctors consistently follow peanut allergy prevention guidelines, potentially reducing the number of infants who develop peanut allergies.
What could go wrong
This is a small, early-stage study focused on doctor behavior, not a direct test of a new treatment. The actual reduction in peanut allergy incidence is a secondary outcome and may not be significant.

Infants • Infant has been seen by a pediatric clinician in the intervention or control arm for a 4- and/or 6-month WCC. Caregivers * Is the caregiver of an infant seen for a 4- and/or 6-month WCC by a pediatric clinician in a practice belonging to the study's intervention or control arms. * Is 18+ years of age or has parent or guardian permission to participate. * Is able to understand the study and provide informed consent for the 12- and 24-month (child's age) survey. Exclusion Criteria: Practice Sites * Sees \<50 newborn patients/year. * Has only temporary pediatricians on staff. * The practice pediatric clinicians do not use an EHR system. Pediatric clinicians * The clinician is a temporary employee. * The clinician begins employment at participating practice less than three months prior to end of the 18-month study enrollment period. Infants * The infant has a medical condition that chronically inhibits the ability to take food orally (i.e., dysphagia, muscular dystrophy, gastrostomy). * The infant has past or current medical problems or findings from physical examination or laboratory testing not listed above for which the pediatric clinician indicates that implementation of PPA Guidelines may pose a medical risk other than allergic reactions or may interfere with the infant's appropriate implementation of the PPA Guidelines or study investigators conclude that implementation of the PPA Guidelines was not possible or may have impacted the quality or interpretation of the data obtained from the study. Caregivers • Caregiver's primary language is not English or Spanish.
