Undernotification of anaphylaxis deaths in Brazil due to difficult coding under the ICD-10
Tanno LK et al. – The study of anaphylaxis mortality using secondary data requires the use of information derived from the underlying as well as from the contributing causes–of–death fields. Coding definitions should be standardized with a view of enabling trend analyses and international comparisons. The ICD–11 revision is a unique opportunity to improve the coding system so as to facilitate epidemiological studies of anaphylaxis mortality.
