    AbstractOur objective was to assess current practices about the administration (intermittent, extended, or continuous infusions) and therapeutic drug monitoring (TDM) of β-lactam antibiotics and vancomycin in France. We conducted a nationwide cross-sectional survey in May-August 2015, using an online questionnaire, sent as an e-mail link to infectious disease specialists and intensive care specialists through national mailing lists. We used clinical vignettes of critically ill patients to assess physicians' practices about administration and TDM practices for amoxicillin, cloxacillin, piperacillin/tazobactam, cefotaxime, ceftazidime, cefepime, meropenem and vancomycin. In all, 507 physicians participated (507/1200, response rate 42%). TDM was rarely available for β-lactams (from 16.5% (81/490) for cloxacillin to 30% (145/490) for ceftazidime), whereas vancomycin TDM was available in 97% (477/490) of the cases. In the clinical vignettes, ceftazidime and piperacillin/tazobactam were the β-lactams administered most frequently by extended or continuous infusions (76% (336/440) and 57% (252/444), respectively). Gaps in knowledge about the duration of stability of intravenous β-lactams were common (correct answers ranged from 8% (35/432) for cloxacillin to 33% (146/438) for ceftazidime). Most physicians (77%, 339/442) were convinced of the value of extended or continuous infusions for β-lactams in critically ill patients, but 48% (211/442) did not have access to practical guidelines. Our survey found that most infectious disease and intensive care specialists are favourable to optimized administration of β-lactams in critically ill patients. But the lack of guidelines and limited TDM availability for β-lactams in hospitals are potential barriers to its implementation.
