Evaluation of an Educational Intervention on Antibiotics in Dental Care
Sponsor: University of British Columbia
Summary
The goal of this randomized trial is to estimate the impact of personalized prescribing portraits and educational materials on prescribing of antibiotic medications by dentists in British Columbia, Canada. The main research question is: Did the prescribing Portraits and Therapeutics Letter lead to a change in clindamycin prescribing as a proportion of total antibiotic prescribing by dentists in British Columbia. Study participants are dentists actively practicing in British Columbia. Participants were randomized to 3 study arms to received different combinations of one of two versions of the individual prescribing Portraits and a Therapeutics Letter in Early or Delayed Groups. Two versions of the prescribing Portrait were used: a "plain" version and a "complete" version, which included an additional section with self-reflection questions for clinicians. 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.

Interventions
Early Plain Portrait and Letter
In the context of audit and feedback interventions, the prescribing Portrait is a document produced by the Therapeutics Initiative that provides personalized prescribing feedback for clinicians in British Columbia. Portraits are used as a practice resource tool for reflection on prescribing or test-ordering patterns. The Portraits provide data of individual prescribing along with evidence-based benchmarks or targets. The "plain" Portrait includes the main message, prescriber's data (compare to optimal prescribing, with or without information on BC mean/median). Prescribers are also given access to a succinct review of the best available evidence on the topic and recommendations for future action in the Therapeutics Letter, a standalone publication that details the evidence for the recommended practice in a brief and practical manner, with references.
Early Complete Portrait and Letter
In the context of audit and feedback interventions, the prescribing Portrait is a document produced by the Therapeutics Initiative that provides personalized prescribing feedback for clinicians in British Columbia. Portraits are used as a practice resource tool for reflection on prescribing or test-ordering patterns. The Portraits provide data of individual prescribing along with evidence-based benchmarks or targets. The "complete" Portrait includes the main message, prescriber's data (compare to optimal prescribing, with or without information on BC mean/median) and a series of self-reflection questions. Prescribers are also given access to a succinct review of the best available evidence on the topic and recommendations for future action in the Therapeutics Letter, a standalone publication that details the evidence for the recommended practice in a brief and practical manner, with references.
