Patient Carrying Time, Confidence, and Training with Epinephrine Autoinjectors: The RACE Survey

Background Limited real-world data exist regarding patient carrying compliance and confidence in using different types of epinephrine autoinjectors (EAIs). Objective To perform a Real-world Assessment of Patients' Carrying Time and Confidence with Epinephrine Autoinjector Devices (RACE survey). Methods This was a noninterventional survey of patients (≥7 years) who filled 1 or more prescription for Auvi-Q or EpiPen between January 2013 and January 2014. Outcomes included proportion of patients carrying their EAI all the time in the last 7 days (primary), EAI use confidence (secondary), and EAI training experience (secondary). Multivariate regression analyses controlled for significant differences in demographic and clinical characteristics between EAI groups. Results The survey included 2000 participants (Auvi-Q, N = 1000 [children, n = 597; adults, n = 403]; EpiPen, N = 1000 [children, n = 105; adults, n = 895]). After adjusting for confounding factors, we found that Auvi-Q respondents were more likely to carry their device all the time in the last 7 days versus EpiPen respondents (adjusted odds ratio [aOR], 1.91; 95% CI, 1.49-2.45; P P P P Conclusions This study suggests significant real-world differences in patients' carrying time, confidence in use, and training experiences between Auvi-Q and EpiPen users.
