Surveillance for carbon monoxide poisoning using a national media clippingservice

Using a novel method to review carbon monoxide (CO) exposures in the US, th e role of CO detectors in prevention of GO-related deaths was studied. Usin g a national media clipping service, CO poisonings reported in the US were analyzed. The impact of CO detectors was investigated through nonfatal outc omes attributable to the presence of CO detectors and case fatality rate co mparison among cities with and without CO detector ordinances. There were 4 ,564 CO exposures resulting in 406 (8.9%) fatalities. Of the exposures 2,61 7 (57.3%) occurred in the home, accounting for 374 (92.1%) deaths, Faulty h eating systems constituted 2,540 (55.6%) exposures and 186 (45.8%) deaths, with alternate heating sources responsible for 389 (8.5%) exposures and 104 (25.6%) deaths. Cities with CO detector ordinances showed lower case fatal ity rates as reported in the media than those cities without ordinances (P <.001), There were 1,008 (24.2%) survivors who attributed their survival to the presence of a CO detector. A media clipping service provided insight i nto CO poisoning demographics. Despite its limitations, this tool may calib rate the positive impact of CO detectors on the prevention of CO-related de aths. Copyright (C) 2001 by W.B. Saunders Company.
