• Have hospital personnel who state that their institution is interested in and would be willing to work to implement MOUD prior to hospital discharge.

• Have hospital staff who express willingness to engage with a site/hub team for training and for data collection.

• Be willing to be randomized to low-intensity or high-intensity implementation support.

Medicaid data must capture at least 3 discharge diagnoses, outpatient MOUD, and be available within no more than 12 months of discharge.
