“I call on the governments of the richest countries to
mandate now that by 2020, all antibiotic prescriptions will need to be informed by up-to-date surveillance information
and a rapid diagnostic test wherever one exists.”

Systematic Review of Existing AMR Diagnostic Technologies
• Overview of the diagnostic technologies that improve the appropriate prescribing of antibiotics
• Comprehensive search of the literature and is divided into applications relevant to primary and secondary care settings
• 69 technologies were assessed in detail
• Lack of progress in developing robust evidence that will impact on practice
