[Demographics, clinical features, treatments, and outcomes of patients who were transferred to emergency facilities in Japan after consuming dangerous drugs].

We conducted a multicenter survey of patients who were transported to emergency facilities in Japan from January 2006 to December 2012 after consuming dangerous drugs. Participants were 518 patients. Harmful behavior was observed at the scene of poisoning for about 10% of patients, including violence to others, and traffic accidents. Some patients had physical complications such as rhabdomyolysis, renal dysfunction, and hepatic dysfunction. Of the 182 patients admitted to hospitals, 29 needed respirators and 21 were hospitalized for ≥ 7 days. Although most patients completely recovered, consuming dangerous drugs can result in physical complications including rhabdomyolysis, as well as physical or neuropsychiatric symptoms, which may require active interventions such as respirator use or prolonged hospitalization.
