A new study finds patients who visited the emergency department for an opioid overdose are 100 times more likely to die by drug overdose in the year after being discharged and 18 times more likely to die by suicide relative to the general population. In the year after emergency department discharge, patients who visited for a sedative/hypnotic overdose had overdose death rates 24 times higher, and suicide rates 9 times higher, than the general population.
