Epinephrine was administered in 49.6% of cases, and a total of 424 patients (2.1% of total cases) died. The frequency of intensive care unit (ICU) hospitalization increased 6.0-fold from 2015 to 2021, and age-adjusted average-weighted mortality rate for anaphylaxis was 0.66 per million. Older age, presence of asthma, and ICU hospitalization were found to be significantly associated with fatal anaphylaxis (p < 0.001 for all). Frequencies of death were 9.1% for venom anaphylaxis, 1.2% in drug anaphylaxis, and 0.2% for food anaphylaxis. Epinephrine autoinjector (EAI) was prescribed for 6.9% of all patients.</div></div><div><h3>Conclusions</h3><div>This is the first study of ED admissions for anaphylaxis using a large, nationwide data from Türkiye. Increasing numbers of ED admissions, ICU hospitalizations and mortality show that anaphylaxis is an important public health issue in Türkiye.</div></div>","PeriodicalId":54295,"journal":{"name":"World Allergy Organization Journal","volume":"18 1","pages":"Article 101019"},"PeriodicalIF":3.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11732556/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142985331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
