Antimicrobial stewardship is the practice of using antimicrobials (antibiotics, antifungals, antivirals) only when they are needed. If they are used when they are unnecessary, they have no benefits and can even cause harm. These include antibiotic resistance and side effects (see below for examples). Some side effects, such as C. difficile diarrhea, can be serious and lead to hospitalization.

Washington State Department of Health is committed to supporting antimicrobial stewardship in multiple settings, including:
- Acute Care Facilities
- Dental Settings
- Nursing Homes
- Outpatient Settings
- Veterinary Settings (University of Washington Center for One Health Research)
Annual Reports
