Global Antimicrobial Resistance Surveillance System (GLASS)

In May 2015, the Sixty-eighth World Health Assembly adopted the global action plan on antimicrobial resistance (AMR). One of its five strategic objectives is to strengthen the evidence base through enhanced global surveillance and research.

WHO developed the Global Antimicrobial Resistance Surveillance System (GLASS) to foster standardized AMR surveillance globally. GLASS currently collects and reports data on AMR rates aggregated at the national level. The system enables comparable and validated data on AMR to be collected, analysed and shared with countries and partners to inform decision-making; to drive local, national and regional action; and to provide the evidence for interventions and advocacy. GLASS also collects data on the implementation status of national surveillance systems.

The methodology and standards used are outlined in the GLASS manual for early implementation. Capacity-building tools, including information technology (IT) resources for AMR surveillance and reporting to GLASS, have been developed and will be made available on the webpage and through the GLASS Secretariat.

How to enrol in GLASS

The first step in enrolment is for countries to submit an expression of interest to participate in GLASS, through which they confirm their commitment to build capacity to collect and share data, as outlined in detail in the GLASS manual for early implementation.

It is recognized that national surveillance systems vary in levels of development and scale. Flexibility has therefore been built into the system. This enables each country to participate from the outset while implementing and strengthening the core components of a national AMR surveillance system, with the aim of generating high-quality data to meet both national needs and GLASS requirements. As an example, once enrolled, countries may start reporting to GLASS immediately on the status of implementation of the surveillance system, prior to sending actual AMR data.

Furthermore, countries that produce data on any one of the AMR markers described in the GLASS manual can submit these, even if they lack data on other AMR markers. Countries can then progressively build capacity to share data on other markers.

Each participating country is expected to nominate a focal point to represent national AMR surveillance within GLASS. An official nomination letter is requested during the registration process. The next steps are as follows:

  • registration in the GLASS IT platform;
  • submission of data on the current status of national AMR surveillance;
  • engaging in technical dialogue on AMR data submission, other issues of AMR surveillance in the country and participation in GLASS.

The first formal GLASS data call for the 2016 data will be open from 1 April to 1 July 2017.

WHO issued a GLASS implementation progress report at the beginning of 2017. The first GLASS report will be published in the fourth quarter of 2017.
