Non-prescription drug-associated out-of-hospital cardiac arrest: Changes in incidence over time and the odds of receiving resuscitation
Main finding · Incidence trends and odds of EMS treatmentResult — go to the resultAdjusted odds ratio 1.34 95% CI 1.13–1.58Authors' conclusion
Although EMS-treated DA-OHCA incidence increased by nearly three-fold, it comprised a minority of the overall OHCA increase during the study period. DA-OHCA was associated with an increased likelihood of EMS treatment.
