TPS 683: Short-term health effects of air pollutants 2, Exhibition Hall, Ground floor, August 28, 2019, 3:00 PM - 4:30 PM Background: CDC’s National Environmental Public Health Tracking Program (Tracking Program) aims to provide information from a nationwide network of integrated unintentional carbon monoxide (CO) poisoning data that could inform relevant public health action and prevention. Methods: The Tracking Program has developed dynamic environmental health surveillance system that includes standard visualization tools such as charts, interactive maps, and tables, and displays a variety of measures of morbidity and mortality (e.g., crude, and age-adjusted rates per 100,000) for unintentional CO poisoning. Users also can explore these measures by cause (i.e., fire, non-fire, unknown intent or mechanism). The hospitalization and emergency department (ED) data are obtained by the Tracking Program from funded state recipients (26 states); mortality data are from the National Vital Statistics System. We pooled the CO poisoning data from 2010-2014, and examined the proportion of unintentional non-fire CO poisonings, and compared state-specific age-adjusted rates during the same period. Results: During 2010-2014, there were more than 4,500 unintentional CO poisoning deaths with an average of 916 deaths annually. Deaths and hospitalizations categorized as non-fire comprised of 41.4%, and 55.4% of cases respectively. During the same period, states that had the two highest annual age-adjusted rate of ED visits for unintentional CO poisoning were Connecticut (AR: 21.4 in 2011) and Vermont (AR=15.7 in 2013), and the highest hospitalization rate were observed in New Mexico (AR: 2.1 in 2011) and Maryland (AR=1.8 in 2009). Conclusions: The Tracking Program demonstrates the opportunity to visualize environmental and health data on one data platform. This allows users to examine temporal and spatial trends and to identify communities at greater risk for CO poisoning. The Tracking Program’s CO poisoning data can be used to drive public health policy and actions that ultimately will reduce the burden of mortality and morbidity for CO poisoning.
