The UK Paediatric Antimicrobial Stewardship (UK-PAS) network’s mission is to create a network of health professionals (including doctors, nurses, pharmacists, clinical scientists, managers, commissioners and the public) to exchange lessons learned from judicious antimicrobial use and to conduct local, regional and international projects destined to ensure safe and effective use of antimicrobials in neonates, children and young people and help address the spread of antimicrobial resistance.
