To explore how model-based geostatistics (MBG) could support trachoma elimination efforts, a technical consultation was held on March 4 and 5, 2024 by the Centre for Health Informatics, Computing, and Statistics at Lancaster University, United Kingdom, a WHO Collaborating Centre on Geostatistical Methods for Neglected Tropical Disease Research. The meeting aimed to foster collaboration for sharing insights on using MBG for decision-making; showcase its applications in assessing trachoma elimination status; address challenges, such as setting the probability threshold for elimination and resolving conflicts between survey and MBG evidence; and discuss considerations for integrating MBG into Tropical Data. Participants, including trachoma program managers, experts, academics, donors, and statisticians, reviewed MBG applications, discussed ongoing studies, identified knowledge gaps, and planned future work. This article summarizes the meeting's presentations, discussions, and outcomes, highlighting current conclusions on and research priorities to evaluate MBG's feasibility and utility in trachoma elimination programs.
