Qualitative assessment of the national initiative to implement antimicrobial stewardship centres in French administrative regions

In May 2020, the French Ministry of Health funded the creation of regional antimicrobial stewardship (AMS) coordination centres (CRAtb) in preparation for the new national framework for the prevention of antimicrobial resistance. This study aimed to assess through qualitative methods the implementation process, the activities carried out, and the interactions with other regional stakeholders of the newly created CRAtb. We conducted a mixed-method study based on a cross-sectional survey and semi-structured interviews by French regions among implemented CRAtb. Of the eight eligible French regions with an existing CRAtb, seven participated to the online survey. Regional partners involved in AMS from the eight regions were interviewed between September 2021 and April 2022. The survey questionnaire addressed, through closed questions, the organization of the CRAtb, articulation with other regional actors involved in AMS and infection prevention and control (IPC), and AMS activities. The semi-structured interviews approached the implementation and the role of CRAtb, and the collaboration of other AMS and IPC stakeholders. Interview transcripts were analysed using thematic content analysis methodology. AMS activities carried out by CRAtb were mainly focusing on hospitals (n = 3), primary care (n = 2) and nursing homes (n = 1). Education mostly relied on training days and AMS help lines, communication on websites and newsletters. CRAtb members reported still being more engaged in providing advice to professionals for individual antibiotic treatments rather than collective-level AMS activities. Interactions were frequent between CRAtb, IPC regional centres and health authorities, but rarely involved other stakeholders. Interviews were performed with 28 professionals involved in AMS from eight regions. Pre-existing networks and working relationships in AMS and more broadly facilitated the implementation of CRAtb. Streamlining and decompartmentalizing IPC and AMS regional activities were considered a way to optimise the prevention of antimicrobial resistance across sectors. The engagement with liberal health professionals was identified as a significant obstacle for CRAtb. Two years after the launch of a new national framework, the implementation of CRAtb appeared complex in most regions. An integrative model joining IPC and AMS efforts, relying on existing networks, with engagement from liberal health profession organisations may be the next pivotal step.
