Background: Multi-institutional, international practice variation of pediatric anaphylaxis management by healthcare providers has not been reported.Objective: Characterize variability in epinephrine administration for pediatric anaphylaxis across institutions, including frequency and types of medication errors. Methods:A prospective, observational, study using a standardized in situ simulated anaphylaxis scenario was performed across 28 healthcare institutions in six countries. The on-duty healthcare team was called for a child (patient simulator) in anaphylaxis. Real medications and supplies were obtained from their actual locations. Demographic data about team members, institutional protocols for anaphylaxis, timing of epinephrine delivery, medication errors, and systems safety issues discovered during the simulation were collected.Results: Thirty-seven in situ simulations were performed. Anaphylaxis guidelines existed in 41% (15/37) of institutions. Teams used a cognitive aid for medication dosing 41% (15/37) of the time and 32% (12/37) for preparation. Epinephrine auto injectors (EAIs) were not available in 54% (20/37) of institutions and were used in only 14% (5/37) simulations. Median time to epinephrine administration was 95 seconds (IQR 77, 252) for EAI and 263 seconds (IQR 146, 407.5) for manually prepared epinephrine (p=.12). At least one medication error occurred in 68% (25/37) of simulations. Prior nursing experience with epinephrine administration for anaphylaxis was associated with fewer preparation (p=.04) and administration (p=.01) errors.Latent safety threats (LSTs) were reported by 30% (11/37) of institutions, more than half of these (6/11) involved a cognitive aid. Conclusion and Relevance:A multicenter, international study of simulated pediatric anaphylaxis reveals: 1) variation in management between institutions in usage of protocols,

Recognition of EG is essential for providing early appropriate empiric antibiotic treatment. An immunologic work-up should be done, although a concomitant viral infection can be the predisposing factor.
