AI Summary & Key Takeaways
AI InsightConclusion: Although overall knowledge of anaphylaxis among audiologists was moderate, only 50.8% identified epinephrine as first-line treatment, 34.4% knew the intramuscular route, and 42.9% knew the correct dose.

Abstract
Aims: Anaphylaxis is a severe systemic hypersensitivity reaction with sudden onset and rapid progression that can be fatal if early intramuscular epinephrine is not administered. Although audiologists frequently work with pediatric and allergic patient populations, their competence in recognizing and managing anaphylaxis has not been systematically evaluated. The aim of this study was to assess audiologists’ knowledge levels regarding anaphylaxis, to identify critical life-saving knowledge gaps, and to determine independent predictors of correct epinephrine and auto-injector use. Methods: In this cross-sectional study, 189 audiologists completed a 22-item knowledge questionnaire covering the definition of anaphylaxis, triggers, clinical manifestations, first-line treatment, epinephrine administration route and dose, and auto-injector use. A total knowledge score (range: 0-22) was calculated. Three critical outcomes were analyzed separately: knowledge that epinephrine is the first-line treatment for anaphylaxis, knowledge that epinephrine should be administered intramuscularly, and knowledge of the correct epinephrine dose (0.01 mg/kg). Independent predictors were evaluated using multivariable logistic regression analysis. Results: The median total knowledge score was 12 (range: 1-22), and the internal consistency of the questionnaire was good (Cronbach’s α=0.793). Only 50.8% of participants correctly identified epinephrine as the first-line treatment for anaphylaxis, 34.4% knew that epinephrine should be administered intramuscularly, and 42.9% knew the correct epinephrine dose. Awareness of epinephrine auto-injectors was identified as the strongest independent predictor of correct dose knowledge (adjusted odds ratio [aOR] 4.28; 95% CI 1.94-9.46; p<0.001). Professional experience significantly predicted knowledge of intramuscular administration (aOR 1.07; p=0.008). Conclusion: Although overall knowledge of anaphylaxis among audiologists was moderate, only 50.8% identified epinephrine as first-line treatment, 34.4% knew the intramuscular route, and 42.9% knew the correct dose. Awareness of auto-injectors was strongly associated with correct dose knowledge (aOR 4.28). These findings highlight critical gaps in life-saving knowledge and the need for targeted training programs.
