Background
Private practice dentists represent 72% of United States’ dentists. We conducted a prospective cohort study of private practice dentists comparing antibiotic use before and after dental antibiotic stewardship education by ID-antibiotic stewardship experts.
Methods
Phase 1 (Pre-education): Three months of retrospective antibiotic data and a pre-survey assessed baseline antibiotic knowledge; Phase 2 (Education): Dentists attended three evening Zoom sessions. Phase 3 (Post-education/Interventions): Three months of prospective audits with weekly feedback. Phase 4: post survey and recommendations to reach more dentists.
Results
Fifteen dentists participated. Ten practiced > 20 years. Pre-survey: 14 were unfamiliar with dental stewardship. The number of antibiotic prescriptions pre/post decreased from 2,124 to 1,816 (p < 0.00001); while procedures increased from 8,526 to 9,063. Overall, appropriate use (prophylaxis and treatment) increased from 19% pre to 87.9% (p < 0.0001) post. Appropriate prophylaxis was 46.6% pre and 76.7% (p < 0.0001) post. Joint implant prophylaxis decreased from 164 pre to 78 (p < 0.0001) post. Appropriate treatment antibiotics pre/post improved 5-fold from 15% to 90.2% (p = 0.0001). Antibiotic duration pre/post decreased from 7.7 (sd = 2.2) days to 5.1 (sd= 1.6) days (p < 0.0001). Clindamycin decreased 90% from 183 pre to 18, post (p < 0.0001). Post survey responses recommended making antibiotic stewardship a required annual continuing education. Study participants invited ID-antibiotic stewardship experts to teach an additional 2,125 dentists via dental study clubs.
Conclusion
After learning dental antibiotic stewardship from ID-stewardship experts, dentists rapidly optimized antibiotic prescribing. Private practice dental study clubs are expanding dental antibiotic stewardship training to additional dentists, hygienists, and patients across the United States.
