Antibiotic use and resistance: a nationwide questionnaire survey among French dentists.

ABSTRACT

The aim of this survey was to describe the attitudes and self-reported practices of French dentists towards antibiotic use and resistance and to compare practices with national guidelines. A nationwide cross-sectional internet-based survey was conducted among the 41,800 French dentists. The online questionnaire was distributed through professional networks from April 2017 to April 2018. Seven-hundred seventy-five dentists participated but only 455 questionnaires were complete enough to be included in the analyses. Amoxicillin was the most frequently prescribed antibiotic (65.8%, 1783/2711), followed by spiramycin + metronidazole fixed-dose combination (11.6%, 312/2711) and amoxicillin-clavulanic acid (10.3%, 279/2711). The main indications for use were abscess (349/423, 82.5%), cervicofacial cellulitis (74.2%, 314/423), and pericoronitis (58.6%, 239/408). Most dentists (90.5%, 381/421) considered that antibiotic resistance is of concern but only half of them (56.3%, 238/423) felt adequately informed about antibiotic use. Many dentists did not comply with the national guidelines the majority of them declared inappropriate antibiotic prescriptions for 11/17 clinical situations. They did not prescribe antibiotics for 5/6 clinical situations requiring prophylaxis. They reported that the publication of clinical guidelines is the main factor influencing their prescriptions (71.0%, 299/421). They wished to receive regular updates of national guidelines in the form of practical sheets (93.0%, 172/185). French dentists should urgently be targeted by antibiotic stewardship initiatives.
