Summary
Diagnostic stewardship can improve care while potentially reducing unnecessary healthcare spending. This practical guide from the SHEA Diagnostic Stewardship Special Interest Group modeled the financial and quality effects of five stewardship interventions spanning laboratory medicine, infection prevention, blood-culture stewardship, and hospital administration. The authors tested their business-case development approach in a 200-bed hospital, estimating approximately $2.5–$2.8 million would be realized in laboratory and clinical savings.
