5 Key Takeaways

• 1

  Patients with out-of-hospital cardiac arrests from anaphylaxis have better neurologic outcomes than those with cardiac causes.

• 2

  Favorable neurologic outcomes at 1 month were 24.2% for OHCA-A compared to 11.7% for OHCA-C (P < .001).

• 3

  Survival rates at 1 month were higher in the OHCA-A group at 33.2% versus 16.1% for OHCA-C (P < .001).

• 4

  Multivariable analysis indicated that OHCA-A was independently associated with improved neurologic outcomes and survival.

• 5

  The study's limitations included lack of posthospital treatment data and variability in diagnosing cardiac arrest etiology.
