The World Health Organization (WHO) has launched a global campaign urging governments to adopt a tool to reduce the spread of antimicrobial resistance.
The AWaRe tool was developed by the WHO Essential Medicines List to contain rising resistance and make antibiotic use safer and more effective.
It classifies antibiotics into three groups – Access, Watch and Reserve – and specifies which antibiotics to use for the most common and serious infections, which ones should be available at all times in the healthcare system, and those that must be used sparingly or preserved and used only as a last resort.
The new campaign aims to increase the proportion of global consumption of antibiotics in the Access group to at least 60%, and to reduce use of the antibiotics most at risk of resistance from the Watch and Reserve groups.
Using Access antibiotics lowers the risk of resistance because they are ‘narrow-spectrum’ antibiotics (that target a specific microorganism rather than several). They are also less costly because they are available in generic formulations.
“Antimicrobial resistance is one of the most urgent health risks of our time and threatens to undo a century of medical progress,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.
“All countries must strike a balance between ensuring access to life-saving antibiotics and slowing drug resistance by reserving the use of some antibiotics for the hardest-to-treat infections. I urge countries to adopt AWaRe, which is a valuable and practical tool for doing just that.”
Currently, it is estimated that more than 50% of antibiotics in many countries are used inappropriately such as for treatment of viruses when they only treat bacterial infections or use of the wrong antibiotic, thus contributing to the spread of antimicrobial resistance.
