Abstract:
Recent studies based on hospital admissions have reported a
significant increase in anaphylaxis prevalence. These studies rely
on accurate diagnosis and coding data from medical records, which has been identified as a potential shortcoming.
The aim of this study was to investigate the extent of anaphylaxis
miscoding, how this changed after intensified training programs
and new anaphylaxis guidelines, and whether this contributed to
apparent changes in prevalence over a 10-year period. This also
provided an opportunity to examine changes in characteristics of
the presenting cases (age and triggers) over time.
