570 Approaching data collection in a liminal health system: engaging migrants and internally displaced communities along the Thailand–Myanmar border

Abstract EP2.4, e-Poster Terminal 2, September 4, 2025, 11:35 - 12:55 Aims People from Myanmar, are one of the most migrated and displaced population in the Southeast Asia region after its 2021 political turmoil. It is estimated that 70% of these migrants move to Thailand particularly along the Myanmar Thai eastern border. In this area, access to healthcare a significant challenge, addressed by a constellation of diverse stakeholders and actors. This study explores how researchers ethically approach data collection in politically sensitive and insecure border regions. Methods The research is part of the study on the liminal Health System along the Thailand–Myanmar border. Fieldwork was conducted in Mae Sot, Thailand, and Myawaddy, Myanmar—areas characterized by high mobility, political unrest, and under resourced health infrastructures. To ensure participant safety and data integrity, the researchers obtained ethical approval from international and border area ethical committees. Early consultations with community-based healthcare providers guided the proposal development and participant recruitment strategies. A stakeholder workshop was conducted to map the local health system and care-seeking pathways using case-based discussions. Participants were recruited for interviews with support from trusted service providers and were scheduled at times and locations chosen by the participants, with attention to personal safety and confidentiality. Following data collection, research findings were shared with stakeholders to verify accuracy and ensure the protection of participants from any harm. The research team finalized the findings by incorporating stakeholder’s feedback. This process also contributed to building and maintaining trust with the community. Results Engaging hidden populations required trust-based relationships, flexible recruitment strategies, and culturally sensitive communication. The dual ethical review process and partnerships with local actors played a critical role in managing risks and enhancing community acceptance. Conclusion Approaching, data collection in fragile settings necessitates ethical rigor, strategic stakeholder engagement, transparent practices and respectful collaboration for accessing and accurately representing the voices of marginalized communities.
