A panel of experts was convened by the Infectious Diseases Society of America to update the 2004 clinical practice guideline on outpatient parenteral antimicrobial therapy (OPAT) . This guideline is intended to provide insight for healthcare professionals who prescribe and oversee the provision of OPAT. It considers various patient features, infusion catheter issues, monitoring questions, and antimicrobial stewardship concerns. It does not offer recommendations on the treatment of specific infections. The reader is referred to disease- or organism-specific guidelines for such support.
