NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Sustaining Public Health Surveillance Systems: A Qualitative Study of Two National Platforms in Thailand
ABSTRACT
Background:
Public health surveillance (PHS) systems are essential for routine disease monitoring, early outbreak detection, and emergency response. Although many studies focus on system development and implementation, less attention has been given to factors that sustain surveillance systems over time.
Objective:
This study aimed to identify factors influencing the sustainability of PHS systems in Thailand by examining stakeholder experiences across two long-standing national surveillance platforms.
Methods:
A qualitative study was conducted using evidence from the malaria surveillance system and the national notifiable disease surveillance system. Semi-structured in-depth interviews and focus group discussions were conducted with stakeholders involved in system development, implementation, operational use, management, and funding. Audio recordings were transcribed and analyzed using thematic analysis.
Results:
Thematic analysis identified seven factors influencing PHS sustainability: user needs, collaboration and partnership, human resources, infrastructure, financial sustainability, ownership, and system adaptability. Sustainability was strengthened when systems fit routine workflows, reduced duplicate work, and produced actionable outputs. The Malaria Surveillance System highlighted the need for context-adapted design in remote settings, while the national notifiable disease surveillance system emphasized interoperability and near real-time national reporting. Key challenges included limited technical capacity, infrastructure maintenance, fragmented lifecycle funding, and unclear operational ownership. Participants also emphasized the importance of moving beyond digitization toward digital transformation that improves efficiency, decision-making, and adaptability.
Conclusions:
Sustaining PHS systems requires more than technical deployment. Long-term viability depends on embedding systems within routine workflows, maintaining human and infrastructure capacity, securing lifecycle financing, establishing clear operational ownership, and enabling continuous adaptation to changing public health and technological needs.
