The changing pattern of acute poisoning may affect complications and outcome in these patients. An update study on acute poisonings was therefore performed and compared to similar data from 1980.


A prospective cross-sectional multi-center study of all adult patients (> or = 16 years) hospitalized in Oslo with a main diagnosis of acute poisoning, irrespective of intention, over a one-year period.


Of 947 admissions, 222 (23%) were comatose. Complications were observed in 173 (18%), slightly reduced from 1980 (22%). Ten (1.1%) died and six (0.6%) got permanent sequelae, of which seven and five were drug- or alcohol-related, respectively. Seventy-five percent received treatment besides observation; 39% received antidotes, increased from 21% in 1980, most frequently flumazenil (23%) and naloxone (14%).


In-hospital mortality in poisoned patients remained low, few patients entailed complications, and most patients survived without permanent sequelae. Drug- and alcohol-abuse related poisonings were most severe.
