The ancillary study will use mixed-methods combining quantitative and qualitative inquiry (interview/focus group and field notes) with administrative and health record data with some analyses including data collected from the parent CTN-0079 (NCT03544112) study. Further, qualitative data will be analyzed in the context of themes derived from CTN-0069 (NCT03023930) and CTN-0079. CTN-0079-A1 is planned to be conducted at two of the three sites of the parent study: (1) Catholic Medical Center, Manchester, New Hampshire; (2) Bellevue/NYU Health and Hospitals, New York, NY. Many of the methods, operating procedures, measures and forms will be retained or adapted from the parent study. However, CTN-0079-A1 is a new study in which lessons learned through the parent study have informed important design modifications necessary to improve study rigor and utility.
As in the parent study, CTN-0079, all clinical care (BUP and referral) will be delivered as part of each facility's clinical protocol, rather than as a research procedure. Implementation Facilitation (IF) activities will continue during ancillary trial preparation with a more intensive booster of IF activities occurring in the last month prior to trial commencement. Thereafter, all study IF support will cease and ancillary study data collection will begin. Data collection will occur over a course of approximately 12 months, divided into two 6-month study periods - the Post-IF and Maintenance Periods. A period of at least 6 months should separate the beginning of the Maintenance Period from the time of last study intervention.
