2007 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 25th Annual Report

Background: This report is the 25th Annual Report of the American Association of Poison Control Centers (AAPCC; http://www.aapcc.org) National Poison Data System (NPDS). During 2007, 60 of the nation's 61 U.S. Poison Centers upload case data automatically. The median upload time is 14 [5.3, 55] (median [25%, 75%]) min creating a real-time national exposure database and surveillance system. Methodology: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Fatalities were reviewed by a team of 29 medical and clinical toxicologists and assigned to 1 of 6 categories according to Relative Contribution to Fatality. Results: Over 4.2 million calls were captured by NPDS in 2007: 2,482,041 human exposure calls, 1,602,489 information requests, and 131,744 nonhuman exposure calls. Substances involved most frequently in all human exposures were analgesics (12.5% of all exposures). The most common exposures in children less than age 6 were cosmetics/personal care products (10.7% of pediatric exposures). Drug identification requests comprised 66.8% of all information calls. NPDS documented 1,597 human fatalities. Conclusions: Poisoning continues to be a significant cause of morbidity and mortality in the United States NPDS represents a valuable national resource to collect and monitor U.S. poisoning exposure cases. It offers one of the few real-time surveillance systems in existence, provides useful data, and is a model for public health surveillance. Copyright © American Association of Poison Control Centers.
