Overview
- The peer‑reviewed analysis published Tuesday looked at 186 countries and used WHO's AWaRe categories to assess which antibiotics are used and which are needed.
- Researchers estimate global need at about 43 billion daily doses in 2019 and note a prior estimate of roughly 40.2 billion daily doses consumed in 2018.
- Most countries overuse 'Watch' antibiotics designed to be restricted while nearly half of countries underuse first‑line 'Access' drugs and about half use fewer 'Reserve' drugs than the study judged necessary.
- The study fills many national data gaps with statistical modelling, which raises uncertainty and means recent, local changes in demand—such as higher Reserve use treating war wounds—are not captured in the 2019 baseline.
- The findings matter for patients because inappropriate choices drive antimicrobial resistance and leave poorer health systems unable to treat severe resistant infections, which could widen health inequities and complicate global stewardship efforts.
