WHO AWaRe

Classification system for antibiotics by the World Health Organization

The World Health Organization (WHO) developed the AWaRe classification to guide antibiotic use.

The WHO AWaRe (Access, Watch, and Reserve) classification is a tool developed by the World Health Organization (WHO) to categorize antibiotics into three groups: Access, Watch, and Reserve. This classification aims to improve the use of antibiotics and combat antimicrobial resistance (AMR) by guiding healthcare providers in selecting the most appropriate antibiotic for specific infections.

Overview

The AWaRe classification was introduced by the WHO to address the growing concern of antimicrobial resistance, which poses a significant threat to global health. By categorizing antibiotics, the WHO aims to promote the rational use of these drugs, ensuring that they remain effective for future generations.

Categories

Access

The Access group includes antibiotics that are recommended as first or second choice for the treatment of common infections. These antibiotics are generally characterized by a lower potential for resistance and are widely available. The goal is to ensure that these antibiotics are accessible to all who need them, particularly in low- and middle-income countries.

Watch

The Watch group consists of antibiotics that have a higher potential for resistance and should be used with caution. These antibiotics are recommended as first or second choice only for specific, limited indications. The use of Watch antibiotics should be closely monitored to prevent the development of resistance.

Reserve

The Reserve group includes antibiotics that should be considered last-resort options. These drugs are reserved for the treatment of confirmed or suspected infections due to multi-drug resistant organisms. The use of Reserve antibiotics should be restricted to preserve their effectiveness.

Implementation

The implementation of the AWaRe classification involves integrating it into national and local guidelines for antibiotic use. Healthcare providers are encouraged to adhere to the classification to optimize antibiotic prescribing practices. The WHO also supports countries in developing policies and strategies to promote the rational use of antibiotics.

Impact

The AWaRe classification has been instrumental in raising awareness about the importance of appropriate antibiotic use. It serves as a framework for healthcare systems worldwide to improve antibiotic stewardship and combat antimicrobial resistance. By categorizing antibiotics, the AWaRe system helps healthcare providers make informed decisions, ultimately contributing to better patient outcomes and the preservation of antibiotic efficacy.
