National-Level Actions Effective at Tackling Antibiotic Resistance

(Press-News.org) National-level policies can reduce the impact of antibiotic resistance across diverse countries, according to a study published April 30, 2025 in the open-access journal PLOS Global Public Health by Peter Søgaard Jørgensen from Stockholm University and the Royal Swedish Academy of Sciences, Sweden, and colleagues.

Antibiotic resistance is a major public health concern, contributing to 1.27 million deaths per year. In 2016, countries around the world committed to developing and implementing national action plans to combat antibiotic resistance. These plans have been criticized for not being fully operationalized. Assessing their impact is challenging—change doesn’t happen overnight, not all countries report their data systematically, and the COVID-19 pandemic disrupted monitoring.

In this study, researchers used the Global Database for Tracking Antimicrobial Resistance Country Self- Assessment Survey (TrACSS) and data on antibiotic use and antibiotic resistance to evaluate the impact of national action over time in 73 countries, representing six continents across high and low-middle income countries. They looked at national trends in indicators related to antibiotic resistance, including antibiotic use, rates of antibiotic resistance, and impact of resistant infections.

By assigning each country an action index, they found that national action was consistently associated with improved indicators of antibiotic resistance. These associations persisted after controlling for factors like socioeconomic conditions, population density, and climate.

Since 2016, both high and low-middle income countries have become more ambitious with their national action plans; only one-third have decreased their efforts to reduce antibiotic resistance.

The authors noted some bias in their sample size in that high-income countries are more likely to have established monitoring systems but stressed the importance of studies like this to establishing the impact of national policies on tackling antibiotic resistance.

 The authors add: “Our research shows the importance of all countries taking additional action to address antibiotic resistance. Very ambitious action will be needed to achieve reductions in resistance, but even incremental improvements will help reduce the projected increases…We were not sure that it would be possible to reduce levels of antibiotic resistance while also keeping using antibiotics to the extent that is required by modern health systems, but our research indicates that it is indeed possible.”
