Exploring stakeholders’ perspectives on antibiogram use, development, and implementation in residential aged care settings

Abstract

BackgroundKnowledge of local antibiotic resistance data provided by antibiograms (cumulative-antimicrobial-susceptibility-tests) can assist prescribers to make appropriate empirical antibiotic choices. ObjectiveThis study explored the perceptions and knowledge of key stakeholders about the role of antibiograms in residential aged care facilities (RACF), and to understand barriers and enablers of antibiogram development and implementation in this setting. MethodSemi-structured interviews were conducted with aged-care health professionals (‘end-users’) and antibiogram content experts. This study was conducted in Queensland, Australia in 2023. Using qualitative techniques, framework thematic analysis was used to identify themes, which were mapped to the ‘Integrated Promoting Action on Research Implementation in Health Services’ framework constructs. ResultsTwenty interviews were conducted comprising of five ‘content-experts’ and fifteen ‘end-users’. Five themes were identified which indicated lack of knowledge about how to use antibiograms, and its availability. Potential insufficient data was the primary issue identified by content experts with regards to feasibility of annual antibiograms. Pragmatic solutions were offered, such as pooling pathology data from facilities in the same geographical location, extending antibiogram data to two-or three-yearly, or utilising local hospital antibiograms. Presenting antibiogram data in a mode and format suiting preferences of individual users would encourage uptake and improve usability. Antimicrobial stewardship (AMS) champions and pharmacists were highlighted as drivers of educating and promoting antibiogram use. ConclusionClinicians recognised the potential role of antibiograms in improving empirical antibiotic prescribing choices. Establishing their baseline knowledge provides an essential starting point for the education needs of this group. This study provides practical recommendations regarding the presentation of antibiograms to ensure appropriate use and uptake as an AMS tool in RACFs. Pragmatic solutions suggested to overcome challenges of antibiogram development for RACFs should be applied and evaluated to determine feasibility of RACF-specific antibiograms.
