This document summarizes recent activities related to antibiotic stewardship in human medicine and animal agriculture. It discusses progress in hospital antibiotic stewardship programs in the US, with the percentage of hospitals meeting CDC core elements increasing from 41% in 2014 to 64% in 2016. For human outpatient antibiotic use, 30% of prescriptions were deemed unnecessary. In animal agriculture, alternatives to antibiotics show promise for growth promotion and disease prevention in chickens. Upcoming priorities include finalizing federal policies on antibiotic stewardship, improving data collection and quality of programs, and prioritizing research on non-antibiotic alternatives.
