We take an evidence-based approach to reaching our goals which informs our decisions and guides our collaborative work.

Each of the treatment programmes we support begins with prevalence mapping to determine risk and routine monitoring and evaluation is an integral part of the programme cycle.

Prevalence Mapping

  • Prior to treatment, we support in-country Ministries of Health to assess the prevalence* of infection.

  • Our biostatisticians develop risk maps, detailing predicted levels of infection across endemic areas.

  • These maps show which areas require treatment and how often to distribute treatment.

  • Schools, and children attending them, are randomly selected to provide samples to test levels of infection before and after treatment.

To determine how often treatment will be needed in an area, the risk level is assessed based on prevalence of infection and according to the World Health Organization guidelines.

Surveys

To ensure that we are supporting national Ministry of Health programmes to optimise our joint efforts and using resources most cost-effectively, we routinely conduct surveys and collect data.

Examples of these surveys are:

Coverage survey

The performance of treatment delivery is evaluated by measuring the treatment coverage (the percantage of school-age children who were targeted for treatment, who go on to swallow the tablets). The World Health Organization’s global goal is for at least 75% of people targeted for treatment, go on to receive it.

Impact survey

Measures how well programmes are performing to reduce levels of infection over time. Surveys are conducted in the same set of schools every year, or every two years, and test for levels of infection by collecting samples from the children.

Data Quality Assessment

A tool developed for programmes to validate the data collected during monitoring and reporting stages in the programmes. The overall management and quality of data is assessed when collecting, transmitting, documenting and reporting data. The assessment looks for completeness, availability, and timeliness of documentation and reporting throughout different levels of the health administration systems. This in turn allows programmes to gauge the reliability and accuracy of the data provided and helps programmes identify areas in need of strengthening.

Social science research

The Social Science unit’s main responsibility is to identify and address barriers for the uptake of treatment against parasitic worm infections. It conducts three types of activities:

  1. It monitors changes in knowledge, understandings, and attitudes concerning treatment campaigns among adults and school-age children.

  2. It assesses the reach, quality, and impact of social mobilisation and sensitisation strategies adopted by local programmes.

  3. It uses evidence from operational research initiatives to design and evaluate behavioural change interventions, in collaboration with partners.

This all helps determine what real-time adaptations may be needed to ensure that programmes continue to have the highest impact and are a best practice in public health.
