Evaluation of effectiveness of education in the management of epinephrine autoinjectors

Introduction: anaphylaxis is a medical emergency and early administration of adrenaline is essential to reduce morbidity and mortality. Adrenaline autoinjectors are available for patients with a diagnosis of anaphylaxis so they can receive the medication without delay. The main goal of our study was to evaluate parental knowledge about anaphylaxis and the use of autoinjectors and whether their knowledge improved after some training. Material and methods: pre- and post-intervention study. We analysed 6 primary care caseloads, selecting patients with a diagnosis of anaphylaxis who had adrenaline autoinjector prescriptions. Participants received 2 emails. The first one included a questionnaire about anaphylaxis and how to use the adrenaline autoinjector. The second one contained informational pages and videos and a second questionnaire. That way we compared parental knowledge before and after receiving some training. Results: food was the main cause of anaphylaxis. Only 56.3% of the participants carried the autoinjector at all times. Comparing the knowledge before and after the intervention, we found improvement in nearly every step of the administration of adrenaline. The improvement was statistically significant when it came to the correct identification of the safety release cap (p 0.018) and the awareness of the possibility of administering a second dose (p 0.006). There was a clear improvement in the knowledge of needing to massage the injection area, but it was not statistically significant (p 0.066) Conclusions: periodic training about how to use the autoinjectors is key to reduce morbidity and mortality in patients with anaphylaxis.
