Overview of services

The Antimicrobial Stewardship and Evaluation Team (ASET) are dedicated to enhancing the quality of antimicrobial use throughout Duke University Hospital.  ASET works collaboratively with clinical pharmacists, medical staff and other healthcare workers to provide safe, efficacious, and cost-effective drug therapy to optimize outcomes in patients with infectious diseases. 

The Duke University Hospital Antimicrobial Stewardship and Evaluation Team (ASET) is co-chaired by Rebekah Moehring, MD, and Christina Sarubbi, PharmD.  ASET is a part of the Duke Center for Antimicrobial Stewardship and Infection Prevention (DCASIP), the Duke University Health System Pharmacy Medication Management Committee (PMMC), and the Duke University Hospital Pharmacy and Therapeutics (P&T) committee. Our team of pharmacists and physicians have worked together to establish ASET as a highly effective and efficient team since 2013.  Put simply, patient care is safer at DUH because of ASET activities.
