Increasing frequency and fatality of poison control center reported exposures involving medication and multiple substances: data from reports of the American Association of Poison Control Centers 1984–2013

Abstract

Multiple substance exposures have become a greater percentage of cases reported to the AAPCC and have higher fatality rates than single substance exposures. The majority of fatal poisonings reported to the AAPCC between 1984 and 2013 involved medication. The percentage of fatal poisonings involving medication increased over the interval, as did the percentage of fatalities involving more than one medication. Fatalities involving multiple medications are now the most common type of fatal poisoning reported to the AAPCC.
