Factors influencing the stewardship activities of antimicrobial management teams: a national cross-sectional survey

Background: The link between inappropriate antibiotic prescribing and the global threat of antimicrobial resistance is well documented. International strategies recommend antimicrobial stewardship (AMS) programmes, with improvement interventions to safeguard antibiotics. Aim: This study sought to systematically evaluate the impact of multi-professional Antimicrobial Management Team (AMT) staff resource availability on stewardship activities. Methods: We conducted an on-line, cross-sectional survey of AMTs in each regional Health Board and the national specialist hospital in Scotland (N = 15). Responses were analysed descriptively, exploring observed relationships between variables to identify patterns. Findings: Results highlighted apparent variation in the levels of AMT resource availability across Scotland, not directly influenced by Health Board size, with some larger Health Boards having proportionately poorer AMT resource allocation. However, the range and frequency of activities to support AMS was not directly linked to either Health Board size or staff resource allocation, indicating a more complex inter-relationship between factors. Conclusions: There is apparent inequity in staff resource available for AMTs across Scotland, with significantly lower resource allocation in comparison with recommendations from other international studies. However, considering these survey findings with our earlier qualitative research indicates that leadership style and team member enthusiasm may be as, if not more, influential than resource availability on the scope of AMT activities. These findings have international relevance for hospital service managers considering the recruitment, training and ongoing support of AMTs, in order to maximize impact from a limited resource.
