Acute poisonings treated in hospitals in Oslo: a one-year prospective study (I): pattern of poisoning

Abstract

Objectives: Prospective design is mandatory to study pattern of poisoning and suicidal intention of patients.

Material and methods: Prospective cross-sectional multi-center study of all patients contacting health care services because of acute poisoning during one year in Oslo, irrespective of intention. Data on the adult hospitalized patients (> or = 16 years) are presented here.

Results: Of a total of 3,775 such adult contacts (3,025 episodes), there were 947 (31 %) hospitalizations; annual incidence 1.9 (per 1,000) in males and 2.1 in females. Median age was 36 years (range 16-89); 54% females. Benzodiazepines (18%), ethanol (17%), paracetamol (12%), opioids (7%), and gamma hydroxybutyric acid (GHB) (7%) were most frequently taken. Patients stated suicidal intention in 29% of the admissions; physicians in 10%.

Conclusion: Benzodiazepines and ethanol were the most common agents, but newer illicit drugs were frequent, especially GHB. Males often took ethanol and drugs of abuse; females often used prescription drugs with suicidal intention.
