The METRe Group at the Liverpool School of Tropical Medicine was established in 2010. This multi-disciplinary group led by Professor Joseph Valadez was created to provide technical assistance and build capacity in low resource countries on how to effectively collect, analyse and use quality data to guide decision making for health programmes and policies.

The groups’ main scope of work includes;

  • Development of innovative tools for monitoring of health programs
  • Development and expansion of the use of Lot Quality Assurance Sampling (LQAS)
  • Accessing difficult to reach populations (for example commercial sex workers) through the use of Respondent Driven Sampling (RDS)
  • Disease monitoring including; HIV, TB, malaria, and major childhood illnesses (e.g. malnutrition, pneumonia and diarrhoea)
  • Child health programme assessment
  • Health facility assessment
  • Health policy and national health strategy development
  • Health system bottle-neck analysis which aims to identify problems within a health system that limit effective service delivery
  • Epidemiological research on disease burden and spread
  • Research on the use of sampling methods and health system strengthening 

The group specialises both in the development of practical tools for assessment, and their use. The main focus of the group is to improve health systems and health care outcomes through integrating effective and practical tools for monitoring through strong training and follow-up strategies. METRe is committed to developing local capacity to undertake this work, and uses a Learning By Doing approach for this purpose. Research is an on-going component of the work of the METRe group who strive to ensure that monitoring strategies are evidence-based and successfully impact on health care.

METRe works closely with a wide array of international agencies such as: DFID, USAID, European Commission, UNICEF, WHO and UNAIDS.
