Hospital emergency departments (EDs) not only care for patients with overdose and other complications from opioid use, but they also serve as vital touch points to engage patients into longer-term treatment. After an overdose, patients are at risk for repeat overdose and death. Pennsylvania is unique in establishing a voluntary incentive program to improve the rate at which patients with opioid use disorder receive follow-up treatment after emergency department care. Evaluations of the program show that financial incentives are effective in producing rapid treatment innovations for opioid use disorder.
