Impact Evaluation of the Therapeutic Initiative's Prescribing Portrait and Therapeutics Letter on Opioid Use by Dentists
Canada3,498 participantsStarted 2026-01-06
Plain-language summary
The aim of this study is to estimate the impact of providing personalized prescribing data and educational materials on opioid prescribing to dentists in British Columbia, Canada.
The main research questions are:
1. What is the impact of an intervention on the use of opioids for dental pain? The intervention includes a personalized prescribing report (a "Portrait"), brief educational summary, and patient education materials; and
2. Does the impact of the intervention increase when dentists are also invited to attend facilitated audit-and-feedback group sessions and to develop a practice improvement plan? Using administrative health data, the prescribing of those in different combinations of materials in the Early Group will be compared to those in the Delayed Group to estimate the impact of the materials on prescribing by the dentists.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
The number of opioid prescriptions per dentist
Timeframe: From baseline to 12 months post interventions. The baseline is the 12-month period before the date when the prescriber is mailed the intervention bundle.
2
Total morphine milligram equivalents (MME) prescribed per dentist
Timeframe: From baseline to 12 months post interventions. The baseline is the 12-month period before the date when the prescriber is mailed the intervention bundle.
