ANTIMICROBIAL resistance (AMR) governance is strengthening worldwide, but new research suggests improvements in national policy frameworks have not yet translated into meaningful reductions in drug-resistant infections.
AMR occurs when bacteria, viruses, and other microbes evolve to survive medicines that once killed them, making infections harder to treat. It is considered one of the most pressing global health threats, responsible for rising illness, deaths, and healthcare costs. While many countries have introduced national action plans to tackle AMR, evidence of their real-world impact has remained limited.
AMR Governance Improving Worldwide
In a large global analysis, researchers developed a new AMR governance index to assess how effectively countries are responding to antimicrobial resistance. The index used a One Health framework, which considers human, animal, and environmental health together.
The study evaluated AMR governance in 193 countries between 2017 and 2022, drawing on 269 policy documents alongside multinational survey and surveillance data. Governance scores improved during the study period, rising from 30.7 to 44.5 out of 100.
However, the analysis found that policy design has advanced faster than implementation. Monitoring systems and practical measures lagged behind, particularly in sectors such as agriculture and the environment where antibiotic use also contributes to resistance.
Delayed Impact on AMR
Despite stronger governance frameworks, measurable improvements in AMR outcomes were slow to emerge. Statistical modelling suggested that changes in resistance levels were not detectable until around 5 years after national action plans were introduced.
This delayed effect highlights the complexity of controlling AMR. Changes in antibiotic use, surveillance systems, and infection control practices can take years to influence resistance patterns across healthcare and community settings.
Key Drivers of Progress
The study identified two governance factors most strongly linked with improvements in AMR outcomes. Countries that adopted early multisector engagement, bringing together human health, veterinary, and environmental sectors, showed better progress over time.
Similarly, strong antimicrobial use surveillance systems, which track how antibiotics are prescribed and consumed, were associated with more favourable trends in resistance indicators.
Regional Differences and Policy Gaps
Progress varied widely between regions. European countries generally demonstrated stronger governance systems, while regions including the Eastern Mediterranean, South-East Asia, and the Americas showed slower improvements in implementation and reporting.
Public awareness campaigns, infection prevention measures, and long-term sustainability planning were also identified as weak areas globally.
Implications for Global AMR Strategy
As global health leaders prepare updates to the international action plan on AMR, the findings emphasise the need to move beyond policy commitments. Experts suggest that sustained funding, integrated surveillance across sectors, and stronger engagement with environmental and agricultural stakeholders will be essential to translate governance improvements into real reductions in antimicrobial resistance.
