This study analyzed the appropriateness of antibiotic prophylaxis in dental visits and found that unnecessary antibiotic prophylaxis was highly prevalent but decreased over time. Factors associated with unnecessary prophylaxis included age, sex, geographic region, rurality, type of antibiotic, and dental procedure. Antimicrobial stewardship strategies targeting dentists are needed.
Introduction: Prescribing antibiotic prophylaxis is common yet unnecessary for many dental visits. In this analysis, our objective was to assess whether the appropriateness of antibiotic prophylaxis has improved over time. Methods: A retrospective cohort study was conducted using dental visits from 2016 to 2018 (data analyzed in 2021) using medical and prescriptions claims data of patients from the U.S. with commercial dental insurance. Antibiotic prophylaxis was defined as a <= 2 days' supply prescription dispensed within 7 days before a dental visit. Appropriateness of prophylaxis was defined on the basis of the manipulation of the gingiva/tooth periapex or oral mucosa perforation in patients with appropriate cardiac diagnoses. Associations between patient and visit characteristics and appropriateness of antibiotic prophylaxis were assessed using multiple Poisson regression. Results: Unnecessary antibiotic prophylaxis was highly prevalent in this cohort, ranging from 77.0% in 2016 to 78.5% in 2018. In the adjusted analysis, factors associated with unnecessary antibiotic prophylaxis included younger age, female sex, geographic region, rurality, type of antibiotic, and certain dental procedures. The factors associated with the highest risk of unnecessary prophylaxis in the adjusted analysis were orthodontic procedures and having a history of a prosthetic joint. Notably, the risk of unnecessary antibiotic prophylaxis decreased over time in the adjusted analysis. Conclusions: Unnecessary prescription of antibiotic prophylaxis by dentists continues to be common. Antimicrobial stewardship strategies are needed to improve prescribing by dentists.
