Understanding dentists' antibiotic prescribing behaviour in Spain: a focus group study.

Background: Dentists are responsible for 10% of all antibiotic prescriptions. It is estimated that, in certain situations, up to 80% of antibiotic prescriptions in dentistry may be inappropriate. The aim of this study was to explore Spanish dentists' attitudes, perceptions, and contextual factors influencing antibiotic use and misuse in clinical practice. Methods: From July to December 2022, we conducted focus groups with 31 dentists from Spain Data were analysed using thematic analysis with a pragmatic orientation to address the research objectives. Inclusion criteria required participants to be dentistry graduates or oral medicine specialists (stomatologists) and actively working as dentists. The sample was selected through key informants and the snowball method. We ensured methodological quality by adhering to the COREQ checklist. Results: We formed seven synchronous online focus groups with 31 participants. Dentists acknowledged the problem of antibiotic resistance, identifying fear, working conditions and burnout and patient trust as factors contributing to inappropriate prescribing. Despite this awareness, dentists did not see themselves as key agents of change in combating antibiotic resistance. However, they expressed interest in further education on the topic. Conclusions: These findings underscore the need for educational interventions that highlight dentists' role in antimicrobial stewardship. By situating these interventions within the One Health framework, dentists can be empowered to translate their leadership in oral health into active participation in the prudent use of antibiotics. Strengthening this role has practical implications for multidisciplinary strategies to combat antimicrobial resistance.
