OBJECTIVE: Each year, approximately 165,000 poisonings are managed in the emergency departments (ED) in France. We performed a descriptive analysis of self-poisoned patients admitted to a university hospital ED in the Paris metropolitan area (France) aimed at investigating their outcome and the risk factors for transfer to the intensive care unit (ICU).
PATIENTS AND METHODS: We retrospectively reviewed patients’ records and performed multivariate logistic regression analysis to identify risk factors for ICU admission.
RESULTS: During 4 years, 882 self-poisoned patients (median age, 38 years [IQR, 26-47]; sex-ratio, 1M/3F) were admitted to the ED, representing 0.7% of all referred patients. Poisonings mainly resulted from multidrug exposures (53%), including benzodiazepines (78%), serotonin reuptake inhibitors (17%), acetaminophen (13%), antipsychotics (9.5%), imidazopyridines (9.5%), antihypertensive drugs (3%), and polycyclic antidepressants (1.3%). Ethanol was involved in 20% of the exposures. Patients were briefly (<24h) monitored in the ED (55%), transferred to the psychiatric department (30%), medical ward (2%) or ICU (6%), and took an irregular discharge (7%). Among the patients transferred to the ICU, 25% were mechanically ventilated and only one died. Risk factors for ICU admission included antihypertensive (Odds ratio (OR), 40.6; 95%-confidence interval (CI), 7.5-221.9) or antipsychotic drug ingestion (OR, 5.3; CI, 2.0-14.4), male gender (OR, 3.3; CI, 1.30-8.8), and consciousness impairment (OR, 2.1; CI, 1.8-2.5 per point lost in Glasgow coma score).
CONCLUSIONS: Deliberate drug exposure represents a frequent cause of ED admission. Psychotropic drugs are most commonly involved. Transfer to the ICU is rare and predicted by male gender, drug class, and coma depth.Free PDF Download
