Associations of Mobile Screening Reminders and Data Interoperability with Preventive Uptake in Migrant Worker Cohorts

Abstract

Preventive healthcare uptake remains significantly low among transient populations, particularly migrant workers, who face systemic structural, financial, and geographical barriers to continuous medical care. This paper investigates the dual influence of mobile screening reminders and backend clinical data interoperability in improving preventive screening rates within a large-scale migrant worker cohort. Using a mixed-methods randomized controlled trial framework, we evaluate the impact of automated, culturally tailored, and linguistically diverse mobile health reminders paired with a standardized, cross-jurisdictional health data sharing platform. Over a twelve-month observational period involving 2,400 participants, the cohort receiving both localized mobile notifications and benefit-optimized clinic-level data exchange demonstrated a substantial, statistically significant increase in the uptake of critical screenings, including cardiovascular assessments, tuberculosis screening, and metabolic panels, compared to the control group receiving standard care. Our findings indicate that digital health interventions are significantly limited when operating in clinical silos. True expansion of preventive uptake requires a unified infrastructure combining personalized user nudging with seamless, standards-compliant Electronic Health Record interoperability across municipal and regional jurisdictions. This integration reduces administrative friction and enhances the continuity of care for transient workforces.
