This guide shares practical experience of the use of antimicrobials in an OPAT setting.We took an evidence based approach to create the guidance. We also used expert consensus and practical experience from across NHS Scotland.

The drug summaries do not provide specific treatment guidelines. Individual patient treatment should take into account the core principles of antimicrobial stewardship. This includes selection of the appropriate antimicrobial for the shortest duration with oral therapy being preferred, whenever possible.
