RESUMEN
Emergency management of deliberate self-poisoning (DSP) by drug overdose is common in emergency medicine. There is a paucity of data about the prehospital care of these patients. The principal aim was to describe the intensity of care received by patients with DSP who were managed by prehospital emergency medical service (EMS) physicians. A 48-h cross-sectional study was conducted in 319 EMS and emergency units in France. Patient and poisoning characteristics and treatments administered were recorded. Complications of poisoning, hospitalization, intensive care unit admission and death were recorded until day 30. The primary endpoint was the probability of receiving prehospital intensive care, including fluid resuscitation, vasopressor therapy, invasive ventilation, or antidotal treatments, depending whether prehospital treatment was carried out by an EMS physician or not. Data from 703 patients (median age was 43 [30-52] years, 288 (40%) men) were analyzed. One hundred and fifteen (16%) patients were attended by an EMS physician. Patients attended by EMS physicians were more likely to receive intensive treatment in the prehospital setting [odds ratio (OR) 7.4, 95% confidence interval 4.3-12.9]. These patients had more severe poisoning as suggested mainly by a lower Glasgow Coma Score (13 [8-15] vs. 15 [15-15]; p < 0.001) and a higher rate of admission to an intensive care unit [29 (25%) vs. 15 (2%), p < 0.001]. Patients with DSP attended by prehospital EMS physicians frequently received intensive care. The level of care seemed appropriate for the severity of the poisoning.
