This is a truly great effort you've made, and congratulations on your abstract's acceptance for poster presentation at the NASN meeting. I would suggest also looking into Eastern Society for Pediatric Research Annual Meeting in Philadelphia, PA in March (https://www.aps-spr.org/regions/ESPR/). The fact that you conducted this project with patients/caregivers as partners is powerful, and this meeting can help give your work a bigger audience in the medical community (this is of interest to ER and primary care docs, and others too). As Maud suggested below, maybe some medical or MPH students can help collect more data and work up another abstract. The ESPR meeting is a really great starting point as it is full of medical students, residents, and other trainees who don't have a ton of experience presenting at national meetings.
