Accuracy (VF: verification factor) of vaccination data in several countries and years, with 95% confidence intervals. 100% accuracy.

Better Evidence for Better Decisions

Sound decision-making has to be informed by the best available evidence. The best available evidence comes from synthesising good quality research, regardless of publication status, country of production or language (i.e. systematic reviews of the literature). However, very often, data is of poor quality and evidence is biased or scarce. Therefore, the evidence we have is not the evidence we want.
To overcome this limitation, Swiss TPH works on generating evidence and knowledge translation to optimize the use of data and evidence for decision making. Activities in this area include:

  • Assessing the quality of programmatic data from vaccination programs (Gavi Alliance) and from malaria, tuberculosis and HIV/AIDS grants (The Global Fund).
  • Analysing microdata from 300 surveys in 100 countries to understand vaccination coverage rates and determinants of non-vaccination
  • Conducting systematic reviews (Cochrane reviews, scoping reviews) on topics related to vaccination, health systems and HIV/AIDS
  • Tracking the utilisation of data in policy and strategic documents from many countries

Even when the best evidence is not available, policy makers must continue to make decisions all the time. Swiss TPH has worked towards helping decision makers' function with imperfect, partial or scarce evidence by:

  • Developing a handbook to offer health systems guidance, accounting for imperfect, partial and scarcity of evidence
  • Contributing to guidelines and recommendations for vaccination (e.g. rotavirus and pneumococcal vaccines), communication interventions (COMMVAC project) and for task shifting at WHO

We cover the whole range of activities in the knowledge translation cycle: from data production up to policy formulation, from evidence generation to guidance production.
