Abstract

Most antibiotic prescribing occurs in primary care, yet resistance policy and costing studies concentrate on hospital settings. This review links the microbiological mechanisms selected for by community prescribing - chiefly plasmid-mediated beta-lactamase spread and efflux upregulation in commensal flora - to their downstream economic consequences. Drawing on published cost models, we estimate that each avoidable community prescription carries a delayed system cost several times its acquisition price, realised as second-line therapy, repeat consultation and eventual hospitalisation. We review which stewardship interventions have demonstrated effect in ambulatory settings, and conclude that delayed-prescription strategies and point-of-care testing show the most consistent return.
