This DNP project sought to evaluate parental perspectives on PCN allergy delabeling in pediatric patients who completed a successful oral PCN challenge. This evaluation was performed at a pediatric primary care department of a Federally Qualified Health Center between the dates of July 5th, 2023, and December 8th, 2023. This project applied the Theory of Constraints by focusing on the first step: identify a system’s constraints (Goldratt & Cox, 2004). The desired outcome of this intervention was to better understand parental perspectives and their level of acceptance of their child’s PCN delabeled status after completing a PCN oral challenge. Through the use of phone surveys, created based on expert opinion and research by Vyles et al. (2018), Lanchover-Roth et al. (2019), and Bourke et al. (2015), we were able to survey 100% of participant’s parents (n = 17). Participants included pediatric patients who had completed a PCN oral challenge during the project’s timeline or within 1 year prior to the project’s initiation. Parents responded with overwhelming positivity to the surveys, with greater than 60% reporting they would be very comfortable with their child receiving PCN in the future and 100% of parents agreeing that their child was no longer allergic to PCN.
