Introduction The Public Access Defibrillation (PAD) Trial demonstrated improved survival of cardiac arrest victims when automated external defibrillators (AEDs) were combined with CPR by lay responders. These PAD sites incorporated American Heart Association (AHA) recommended elements of a PAD site and the volunteer responders received refresher CPR/AED training. It is unknown if typical community PAD sites maintain these elements after initial program development. The Johnson County Early Defibrillation Task Force (JCEDTF) in Johnson County, IA distributed AEDs throughout the county in 2002. CPR training was provided at program initiation. The purpose of this study was to evaluate the PAD sites 5 years later to assess compliance with AHA recommendations. Methods A 25 point scoring system was developed to assign numerical values to the components of a PAD site: planned and practiced response, links with local EMS, and training of rescuers. Surveys were mailed to all 39 PAD sites. Site visits with tours were conducted at each the site to confirm the survey. Sites were grouped into educational, community, or business sites. Results Thirty two surveys were returned (response rate 82%): 5 educational sites, 13 business and industrial sites and 14 community sites. The Table shows the percentage of points that each group achieved for the components of an AED program. No site had incorporated all the recommended elements: the best sites included only 2/3 of the recommendations. There was a statistical difference in CPR training, with business and industrial sites performing best. Community sites were particularly weak with CPR training. Conclusions PAD sites incorporate approximately half of the elements of an effective PAD program. Business and industrial sites perform slightly better than educational or community sites. CPR training and EMS links are the poorest areas of compliance. These results may indicate that the effectiveness of a PAD site may diminish with time. Table: Percentage of Achieved Points
