title: A comparative prospective study of self-poisoned patients in Trondheim, Norway between 1978 and 1987: epidemiology and clinical data.
abstract: 1. In a prospective study of patients hospitalized for deliberate self-poisoning between 1978 and 1987 the number of admissions increased from 303 to 425. The annual incidence increased significantly for both women (P less than 0.05) and men (P less than 0.01). The mean age decreased significantly in the male group (P less than 0.05), but increased in the female group (P less than 0.05). 2. The median latency time for patients presenting at the hospital was short; 3.7 h in 1978 and 2.9 h in 1987. 3. There was a significant reduction in the percentage using barbiturates (9% in 1978 and 1% in 1987; P less than 0.001) and the use of benzodiazepines increased (18% in 1978 and 32% in 1987; P less than 0.05). The percentage of unconscious patients did not change significantly. 4. In 1987 N-acetyl-cysteine was the most frequently used antidote. Physostigmine has almost been abandoned since 1978. 5. Significantly more patients were hypotensive in 1978: 24% vs 11% in 1987; (P less than 0.001) and significantly less patients needed treatment in the central intensive care unit (2% in 1987 and 5% in 1978; P less than 0.05). Complications were few (8-10%) and the mortality low (approximately 1%) in both years studied. 6. The mean duration of hospitalization in 1978 was 65 h vs 30 h in 1987, (P less than 0.001).
