About this trial

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.
