Antibiotic Stewardship

An antibiotic order is a clinical hypothesis: a particular pathogen, at a particular site, is causing illness that will improve with this drug. The hypothesis may be reasonable before cultures return, but it must be revisited as the patient’s trajectory and microbiology become clearer. Antimicrobial stewardship is the coordinated effort to use the right agent, dose, route, and duration for that patient. It is not withholding treatment to save money. It protects the patient in front of you from treatment failure, toxicity, and Clostridioides difficile infection while reducing selection pressure that makes future infections harder to treat. The RN sees the treatment timeline more continuously than any single prescriber may: whether cultures were collected appropriately, whether each dose was given on time, whether renal function has changed, whether the patient can now take oral medication, and whether the original indication still makes sense. Those observations create the safety checkpoints that turn an empiric order into a deliberate course of therapy.
