Design outcomes

Primary

MeasureTime frame
The primary feasibility outcome is the number of eligible patients enrolled per week over the 12-week recruitment period (assessed using recruitment records; pre-baseline).

Secondary

MeasureTime frame
1. Percentage of screened patients eligible for inclusion and reasons for ineligibility (assessed from screening forms; pre-baseline). 2. Percentage of eligible patients who consent to participate and reasons for refused consent (assessed from screening forms; pre-baseline) 3. Adherence to telephone system based on matches between self-login at pharmacy and dispensing records (N days where these match/N days total) (assessed from phone system database; continuously during 12-week follow-up). 4. Number/percentage attending follow-up interview (assessed at follow-up interview at 12 weeks). 5. Number/percentage of weeks on supervised consumption during 12-week intervention (assessed from phone system database over 12-week intervention period; and pharmacy records at end of intervention period). 6. Number/percentage on supervised consumption at end of 12-week intervention period (assessed from phone system database at 12 weeks; and pharmacy records at end of intervention period). 7. Number of restarts during 12-week intervention period (where a participant misses >3 appointments and needs to re-present at the clinic to restart their prescription) (assessed from phone system database and pharmacy records extracted at 12 weeks). 8. Number of days from last dose (i.e., last attendance at supervised consumption appointment) until prescription restart (assessed from phone system database and pharmacy records extracted at 12 weeks) 9. Qualitative assessment of clinician perspectives on the revised eligibility criteria (assessed via interviews at 12-14 weeks).
