What is the Purpose of AMR Surveillance?

Published in AMR Surveillance 3 mins read

Antimicrobial Resistance (AMR) surveillance is a critical public health tool designed to systematically collect, analyze, and interpret data on the occurrence and spread of antibiotic-resistant infections. Its primary purpose is to provide the foundational insights necessary to understand, respond to, and mitigate the global threat of antimicrobial resistance.

Core Objectives of AMR Surveillance

AMR surveillance serves as the cornerstone for a comprehensive approach to combating resistance. By continuously monitoring the trends of resistance, it enables health authorities to make informed decisions and implement effective interventions.

The key objectives include:

  • Informing Policies and Infection Prevention and Control (IPC) Responses: Surveillance data directly guides the development of evidence-based policies and guidelines for the appropriate use of antimicrobials and robust infection control measures. This includes identifying specific resistance patterns that require targeted interventions in healthcare settings and communities.
  • Assessing the Spread of AMR: It allows for the mapping of the geographical spread and evolution of resistant pathogens. This helps in identifying new threats, understanding transmission pathways, and prioritizing areas or populations at higher risk.
  • Informing and Monitoring the Impact of Strategies: AMR surveillance is essential for tracking the effectiveness of local, national, and global strategies aimed at controlling antimicrobial resistance. This includes evaluating the success of antibiotic stewardship programs, vaccine initiatives, and public health campaigns. If a strategy isn't yielding the desired results, surveillance data provides the evidence needed for adjustments.

Practical Insights and Applications

Effective AMR surveillance involves a multi-pronged approach, encompassing various data sources and analytical methods.

  • Identifying Trends: By collecting data over time, surveillance systems can detect increasing or decreasing rates of resistance to specific antibiotics, signaling the need for action or confirming the success of interventions.
  • Guiding Treatment Guidelines: When resistance patterns emerge or shift, clinical treatment guidelines can be updated to recommend alternative antibiotics or therapies, ensuring patients receive effective care.
  • Prioritizing Research and Development: Surveillance helps identify critical gaps in treatment options due to widespread resistance, guiding research efforts towards new antibiotics, diagnostics, or vaccines.
  • Facilitating Global Collaboration: International surveillance networks, such as the Global Antimicrobial Resistance and Use Surveillance System (GLASS), enable countries to share data and coordinate global responses to AMR, recognizing that resistance knows no borders.
  • Raising Awareness: Communicating surveillance findings to policymakers, healthcare professionals, and the public helps raise awareness about the AMR crisis and fosters responsible antimicrobial use.

Why is Continuous Surveillance Crucial?

AMR is a dynamic and evolving threat. Bacteria and other microbes constantly adapt, making continuous surveillance indispensable. Without robust surveillance, public health authorities would be operating in the dark, unable to accurately assess the scale of the problem, identify emerging threats, or measure the impact of their efforts. It provides the essential intelligence to protect the efficacy of life-saving medicines for future generations.
