AWaRe – a new WHO tool to help countries improve antibiotic treatment, increase access and reduce resistance. We can reduce or even reverse antibiotic resistance by using antibiotics more responsibly. But how do we do that and still ensure that patients are treated effectively?WHO has developed a tool to help global, regional and national decision-making on which antibiotics to use when. The tool indexes the most effective antibiotics into three groups – ACCESS, WATCH, RESERVE (AWaRe for short). Evidence shows that to optimize use of antibiotics and reduce resistance, countries should increase the proportion of ACCESS antibiotics to correspond to at least 60% of total national consumption.
