Hospitalizations due to poisonings in Finland.

Poisonings constitute an important category of causes for admission of patients to the emergency room. The annual incidence of hospitalized poisonings in Finland over 2 years (1987-1988) was 11.7 for a population of 10,000 according to the Hospital Discharge Register; it was 8.7/10,000 for drugs and 3.0/10,000 for non-drugs. Children under 6 years of age were most frequently hospitalized because of poisoning (16.9/10,000), followed by adults aged 25-44 years (14.8/10,000). The leading causes of poisoning or chemical injury in children were undefined non-drug poisonings; plants, berries and mushrooms mistaken for edible food, and corrosives. In patients aged 6 years or more, mainly adults, the leading causes were psychotropic drugs, ethanol, and cardiovascular drugs. The pattern of poisoning has changed markedly during the 1980s; the rate of psychotropic and sedative drug poisoning admissions have increased from 35 to 47%, and poisonings due to analgesics have also increased significantly. Conversely, poisonings caused by cardiovascular drugs and antibiotics, solvent poisonings and incidents caused by corrosives have decreased significantly (p < 0.001).
