Barriers and facilitators to guideline concordant dental antibiotic prescribing in the United States: a qualitative study of the National Dental PBRN.
This study investigates factors influencing antibiotic prescribing practices among dentists in the United States, aiming to identify barriers and facilitators to guideline-concordant prescribing. While previous research has described factors contributing to dental antibiotic overprescribing, it lacked a theoretical behavior change framework that could guide future intervention development. The research involved semi-structured interviews with dentists from the National Dental Practice Based Research Network, exploring patient and practice factors perceived to impact antibiotic prescribing decisions. The interview data were analyzed and organized using the COM-B model to inform prospective interventions. The study identified three broad targets to support appropriate dental antibiotic prescribing: increasing visibility and accessibility of guidelines, providing additional guidance on antibiotic prescribing in dental scenarios without clear guidelines, and education and communication skills-building focused on discussing appropriate antibiotic use with patients and physicians.

Changes in antibiotic prescribing by dentists in the United States, 2012-2019.
Dentists are the top specialty prescriber of antibiotics in the United States, prescribing 10% of all outpatient antibiotics. The purpose of this retrospective study was to assess trends in the rates of antibiotic prescribing by dentists. The researchers also evaluated if trends varied by agent, specialty, and patient characteristics. The study found that between 2012 and 2019 dentists wrote more than 216 million antibiotic prescriptions. The annual rate of dental antibiotic prescribing remained steady over time. However, the dental prescribing rate increased in the Northeast, among oral and maxillofacial surgeons, prosthodontists, endodontists, periodontists, and for amoxicillin. The mean days' supply significantly decreased over the study period by 0.023 days per 1,000 dentists per year.

Serious antibiotic-related adverse effects following unnecessary dental prophylaxis in the United States.
The majority of antibiotics prescribed before a dental visit are considered unnecessary (80.9%). This study characterized adverse effects related to unnecessary dental prophylaxis. This retrospective cohort study used data from dental visits between 2011 and 2015 from the IBM Watson Health Marketscan Commercial Claims/Encounters, Medicare Supplemental, Coordination of Benefits Research databases. Antibiotics prescribed included amoxicillin (67.9%), clindamycin (15.5%), cephalexin (8.6%), azithromycin (2.8%), and penicillin (1.5). Antibiotic adverse effects (AAEs) were found in 1.4% of unnecessary prescriptions. The most common AAEs were emergency department (ED) visits, allergic reactions, 14 cases of C. difficile infection, and 5 anaphylactic reactions. AAEs were more common with clindamycin than amoxicillin.

Successful implementation of an antibiotic stewardship program in an academic dental practice.
Researchers created a comprehensive antibiotic stewardship program (ASP) for dental practices. A baseline needs assessment and literature evaluation was conducted by a team of dentists, pharmacists, and physician leaders. An academic dental center in Illinois that is the state鈥檚 largest oral health provider for Medicaid recipients was used. After intervention with the ASP, there was a 72.9% decrease in antibiotic prescribing for urgent care visits.
