For improving antimicrobial stewardship globally, several things would need to be coordinated:
Databases about outbreaks and bugs becoming resistant.
Broadscale rapid diagnostics would need to be in place to detect the bugs and resistance.
Improved antimicrobial stewardship, so the antibiotics we use today will still work in 20 or 30 years.
Defined rapid diagnostics reimbursements schemes.
Defined incentives for the development of new antibiotics.
