AEDs do not reduce in-hospital mortality

The use of AEDs in hospitals is enticing since they are easy to use, and they have reduced out of hospital cardiac death. In this large analysis of the NRCPR database, 18% of patients had shockable rhythms, and 18% survived to hospital discharge. Of those with shockable rhythms, AED use did not reduce in-hospital mortality. And overall, the use of AEDs increased in-hospital mortality, due to an increased risk of mortality among patients with non-shockable rhythms. Use of AEDs in hospitals may not be beneficial, where the majority of arrests are not due to shockable rhythms, whereby AEDs may interfere with appropriate care (abstract).
