AbstractAbstract PDF
Purpose: This study was conducted to investigate the frequency and clinical characteristics of anaphylaxis patients who are registered inaccurately with other disease codes. Methods: Study subjects presenting at the emergency department (ED) were retrospectively collected using disease codes to search for anaphylaxis patients in a previous studies. The study group was divided into an accurate and inaccurate group according to whether disease codes were accurately registered as anaphylaxis codes. Results: Among 266 anaphylaxis patients, 144 patients (54%) received inaccurate codes. Cancer was the most common comorbidity, and the radio-contrast media was the most common cause of anaphylaxis in the accurate group. Cutaneous and respiratory symptoms manifested more frequently in the inaccurate group, while cardiovascular and neurological symptoms were more frequent in the accurate group. Blood pressure was lower, and shock and non-alert consciousness were more common in the accurate group. Administration of intravenous fluid and epinephrine use were more frequent in the accurate group. Anaphylaxis patients with a history of cancer, shock, and epinephrine use were more likely to be registered as anaphylaxis codes accurately, but patients with respiratory symptoms were more likely to be registered with other disease codes. Conclusion: In cases of anaphylaxis, the frequency of inaccurately registered disease codes was higher than that of accurately registered codes. Anaphylaxis patients who were not treated with epinephrine at the ED who did not have a history of cancer, but had respiratory symptoms were at increased risk of being registered with disease codes other than anaphylaxis codes.
