Advancing Diagnostic Stewardship for Healthcare-Associated Infections, Antibiotic Resistance, and Sepsis.

Diagnostic stewardship means ordering the right tests for the right patient at the right time to inform optimal clinical care. Diagnostic stewardship is an integral part of antibiotic stewardship efforts to optimize antibiotic use and improve patient outcomes, including reductions in antibiotic resistance and treatment of sepsis. The Centers for Disease Control and Prevention's Division of Healthcare Quality Promotion hosted a meeting on improving patient safety through diagnostic stewardship with a focus on use of the laboratory. At the meeting, emerging issues in the field of diagnostic stewardship were identified, awareness of these issues among stakeholders was raised, and strategies and interventions to address the issues were discussed-all with an emphasis on improved outcomes and patient safety. Here, we summarize the key takeaways of the meeting including needs for diagnostic stewardship implementation, promising future avenues for diagnostic stewardship implementation, and areas of needed research.
