Antimicrobial Stewardship Program

Antibiotic resistance is now a major issue confronting healthcare providers and their patients.  Changing antibiotic resistance patterns, rising antibiotic costs and the introduction of new antibiotics have made selecting optimal antibiotic regimens more difficult now than ever before.

Established in 2001, the Johns Hopkins Antimicrobial Stewardship Program is responding to these challenges through education and research.  The program mission is to ensure that every patient at the Johns Hopkins Hospital who needs antimicrobial therapy gets optimal drug choice, dose, duration, and route of administration while minimizing resistance development and toxicity.
