BACKGROUND: The purpose of this study was to describe the public locations of cardiac arrest and to estimate the annual incidence of cardiac arrest per site to determine optimal placement of automatic external defibrillators (AEDs). This was a retrospective cohort study. METHODS AND RESULTS: Locations of cardiac arrest were abstracted from data collected by emergency medical service programs in Seattle and King County, Washington, from January 1, 1990, through December 31, 1994. Types of commercial and civic establishments were tallied and grouped into 23 location categories consistent with Standard Industrial Codes, and the number of sites within each location category was determined. With the addition of "public outdoors" and "automobiles" as categories, there were 25 location categories. During the study period, 7185 arrests occurred, 1130 (16%) of which were in public locations. An annual incidence of cardiac arrest per site was calculated. Ten location categories with 172 sites were identified as having a higher incidence of cardiac arrest (> or = .03 per year per site). Thirteen location categories had a lower incidence of arrest (< or = .01 per year per site). There were approximately 71,000 sites within these categories. CONCLUSIONS: Placement of 276 AEDs in the 172 higher-incidence sites would have provided treatment for 134 cardiac arrest patients in a 5-year period, 60% of whom were in ventricular fibrillation. We estimate between 8 and 32 lives could be saved in 5 years. To cover the remaining 347 arrests occurring in public in a 5-year period, defibrillators would have to be placed in 71,000 sites, not including outdoors and automobiles. Placement of AEDs in public locations can be guided by the site-specific incidence of arrest.
In our study on Psychiatry, Mass Media and Public Opinion we made a content analysis of newspaper reports on ECT and electric defibrillation. We traced only few special articles on the subject in the 1994 and 1995 CD-Rom versions of the "Der Spiegel", The "Frankfurter Allgemeine Zeitung" (FAZ), the "Neue Zürcher Zeitung" (NZZ) and the "Berliner Tageszeitung" (taz), although the word "Elektroschock" was employed 118 times. Even in high standard newspapers the style of language becomes special when they deal with ECT. The articles are strongly biased and lack informations. In contrast to Defibrillation ECT is not generally accepted. Referring to ECT horror pictures of past psychiatry are cited. The language used is biased and discriminative. Referring to Defibrillation technical details are described and the language is neutral. The social representation of ECT is completely negative.
