About this study
Official title: Reducing the Rate of Missed Appointments in an Outpatient Substance Use Treatment Clinic in Norway
Missed appointments to outpatient substance use treatment are common and costly and can have a negative effect on the health of patients.
In this quasi-experimental study, the investigators used an on-off design to examine whether a reminder "plus" intervention (telephone call from therapist before first appointment) would increase attendance and improve cancellation and rebooking practices. Secondary outcomes included satisfaction with treatment and intention to complete the treatment program.

| Study group | Role | What they receive |
|---|---|---|
| OFF intervention | No intervention | No reminder plus (telephone reminder from therapist) but standard test message reminder (SMS) from second admission |
| ON intervention | Experimental | Reminder plus (telephone reminder from therapist) AND standard test message reminder (SMS) from second admission Receives: Other: Reminder plus (telephone call from therapist) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Attendance rate
Attendance rate at first admission and during 10 outpatient sessions
Measured: Up to 10 treatment sessions, estimated average timeframe = 3 months
Secondary outcomes (2)
Dropout rate
Dropout rate within 10 sessions - measured as formal discharge and/or "technical discharge" (3x no-shows)
Measured: Up to 10 treatment sessions, estimated average timeframe = 3 months
Cancellation / rebooking rate
Examine difference in cancellation / rebooking rate between the two conditions. Data was collected from administrative patient records.
Measured: Up to 10 treatment sessions, estimated average timeframe = 3 months
