Location of Cardiac Arrests in the Public Access Defibrillation Trial

Background. The Public Access Defibrillation (PAD) Trial found an overall doubling in the number of out-of-hospital cardiac arrest (CA) survivors when a lay responder team was equipped with an automated external defibrillator (AED), compared with cardiopulmonary resuscitation (CPR) alone. Objectives. To describe the types of facilities that participated in the trial andto report the incidence of CA andsurvival in these different types of facilities. Methods. In this post-hoc analysis of PAD Trial data, the physical characteristics of the participating facilities andthe numbers of presumed CAs, treatable CAs, andsurvivors are reported for each category of facilities. Results. There were 625 presumed CAs at 1,260 participating facilities. Just under half (n = 291) of the presumed CAs were classified as treatable CAs. Treatable CAs occurred at a rate of 2.9 per 1,000 person-years of exposure; rates were highest in fitness centers (5.1) andgolf courses (4.8) andlowest in office complexes (0.7) andhotels (0.7)...
