2012 Annual Report of the American Association of Poison Control Centers ’ National Poison Data System (NPDS): 30th Annual Report

摘要

Background: This is the 30 th Annual Report of the American Association of Poison Control Centers ’ (AAPCC) National Poison Data System (NPDS). As of July 1, 2012, 57 of the nation ’ s poison centers (PCs) uploaded case dataautomatically to NPDS. The upload interval was 7.58 [6.30, 11.22] (median [25%, 75%]) min, creating a near real-time national exposure and information database and surveillance system. Methodology: We analyzed the case data tabulating specifi c indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identifi ed. Poison center cases with medical outcomes of death were evaluated by a team of 34 medical and clinical toxicologist reviewers using an ordinal scale of 1 – 6 to assess the Relative Contribution to Fatality (RCF) of the exposure to the death. Results: In 2012, 3,373,025 closed encounters were logged by NPDS: 2,275,141 human exposures, 66,440 animal exposures, 1,025,547 information calls, 5,679 human confi rmed nonexposures, and 218 animal confi rmed nonexposures. Total encounters showed a 6.9% decline from 2011, while healthcare facility (HCF) exposure calls increased by 1.2%. All information calls decreased by 14.8% and HCF information calls decreased by 1.7%, medication identifi cation requests (Drug ID) decreased by 22.0%, and humanexposures reported to US PCs decreased by 2.5%. Human exposures with less serious outcomes have decreased by 3.7% per year since 2008, while those with more serious outcomes (moderate, major, or death) have increased by 4.6% per year since 2000.
