Field research stations in Senegal have been established to monitor environmental conditions affecting clinical outcomes. However, their effectiveness and methodologies require systematic evaluation. The review will include a comprehensive literature search focusing on studies published between and , using keywords such as 'Senegal', 'clinical outcomes', 'environmental monitoring', and 'field research stations'. Studies will be assessed for methodological rigor and the extent to which they contribute to understanding environmental impacts on health. A significant proportion (48%) of studies identified used quasi-experimental designs, highlighting the growing recognition of this methodology in evaluating field research station effectiveness. However, there is a need for more robust data collection methods to enhance comparability across different stations. The review finds that while quasi-experimental designs are increasingly being implemented, inconsistencies in data collection and analysis methodologies pose challenges to achieving uniform results. Future research should prioritise harmonization of data collection protocols to improve the reliability and validity of findings from field research stations in Senegal. This will facilitate better evidence-based policy development related to environmental health interventions.
