There is growing recognition of the need for approaches to initiate treatment wherever patients touch the health care system, including the Emergency Department (ED). Most research has focused on initiation of medications for opioid use disorder (MOUDs) in the ED rather than ensuring continued treatment post-discharge. The investigators propose to adapt evidence-based interventions to support patients' complex needs and facilitate continued treatment, rather than discharging them and having them navigate outpatient treatment systems with limited support. The research team will randomize participants into 1 of 4 arms to receive varying degrees of augmented usual care, including daily check-ins and contingency management. The investigators plan to examine the effects of check-ins and contingency management on engagement with addiction treatment and equity of treatment effects among racial and ethnic subgroups and assess important moderators of treatment effects.
