Setting up laboratory-based antimicrobial resistance surveillance in low- and middle-income countries: lessons learned from Georgia

Abstract

Background: Antimicrobial resistance (AMR) is a growing problem worldwide, with an estimated high burden in low- and middle-income countries (LMICs). In these settings, tackling the problem of AMR is often constrained by a lack of reliable surveillance data due to limited use of microbiological diagnostics in clinical practice.

Objectives: The aim of this article is to present an overview of essential elements for setting up an AMR surveillance system in LMICs, to summarize the steps taken to develop such a system in the country of Georgia, and to describe its impact on microbiology laboratories.

Sources: A literature review of published papers using PubMed and experiences of experts involved in setting up AMR surveillance in Georgia.

Content: Basic requirements for implementing a laboratory-based surveillance system in LMICs can be captured under four pillars: (a) governmental support, (b) laboratory capacity and quality management, (c) materials and supplies, and (d) sample collection, data management, analysis and reporting. In Georgia, the World Health Organization Proof-of-Principle project helped to start the collection of AMR surveillance data on a small scale by promoting the use of microbiological diagnostics in clinics, and by providing training and materials for laboratories. Thanks to governmental support and a strong lead by the national reference laboratory, the AMR surveillance network was sustained and expanded after the project ended.

Implications: This review describes the Georgian approach in building and expanding a functional AMR surveillance system, considering the elements identified from the literature. The introduction of quality management systems, standardization of guidelines and training paired with targeted capacity building led to improved laboratory standards and management of patients with bloodstream infections. Reliable AMR surveillance data may inform and facilitate policy-making on AMR control. The Georgian experience can guide other countries in the process of building up their national AMR surveillance system.
