Are automated external defibrillations (AEDs) in private homes effective and cost-effective?In this cohort study including 582 536 patients, survival was better with AED application compared with no AED application in patients with a shockable rhythm but not in those with a nonshockable rhythm. AEDs were not cost-effective.AEDs in private homes are effective at improving outcomes for patients with cardiac arrest, but the indiscriminate purchase of AEDs for private homes is not cost-effective at the current pricing of AEDs.
