A nationwide survey on involvement of clinical microbiologists in antibiotic stewardship programmes in large French hospitals

Abstract : Antibiotic stewardship programmes (ASP) are essential to tackle antibiotic resistance. Clinical microbiologists (CMs) play a key role in these programmes; however, few studies describe their actual involvement. Our objective was to explore CMs' involvement in French hospital ASP. In 2018, we conducted a survey among CMs working in large public French hospitals (600 acute care beds or more). The questionnaire focused on the following topics microbiology department's characteristics, hospital ASP, and CMs' involvement in this programme, including their use of rapid diagnostic tests (RDT). Fifty/74 CMs answered (response rate 68%), with 68% working in a teaching hospital. CMs were leading the ASP in 6% of cases, and 57% of hospitals had a multidisciplinary antibiotic stewardship team. Most microbiology departments (92%) were using specific PCR, processed 24/7 in 74% of hospitals. More than half (58%) were using syndromic panel-based testing, 94% mass spectrometry, and 96% immunochromatographic/colorimetric RDT. Blood cultures were processed 24/7 in 44% of hospitals. CMs were involved in this. Finally, 42% of CMs wished to be more involved in their hospital's ASP, the most frequently reported barrier being lack of time (36%). CMs should be more involved in ASP. RDT are widely used, but not implemented in an optimal way.
