Conclusion
In conclusion, we report an increase in anaphylaxis incidence between
2009 and 2019 in Asian populations, comparable to the Western world.
Fewer than 15% of anaphylaxis patients were prescribed with AAI, which
was low compared to countries with similar disease burden. AAI was less
likely to be prescribed to the adult patients, highlighting the
discrepancy in anaphylaxis care between adult and pediatric patients.
These findings highlight the urgent need for enhanced allergy education
for both hospital-based physicians and family physicians in the
community in order to optimize management of anaphylaxis and timely
prescription of AAI. Local or regional anaphylaxis registries using
standardized anaphylaxis definition, methodology and data collection are
in dire need.
