Successful antibiotic stewardship in the electronic era.

A multi-faceted antimicrobial stewardship programme contributed to a 17.8% reduction in antibiotic consumption for our English NHS Trust. This dramatic achievement could be partially attributed to an empirical antibiotic guideline change, introduction of procalcitonin testing to guide in antibiotic decisions in SARS-CoV-2 inpatients and use of electronic antibiotic stewardship strategies. In this article, we describe the multifaceted, step-by-step antibiotic stewardship approach that weathered the SARS-CoV-2 pandemic and led to this dramatic improvement. Also included for completeness are interventions that did not pass the plan, do, study, act (PDSA) cycle and were therefore discontinued.
