A comprehensive scoping review in Global Health Action identifies three critical success factors for implementing mobile health-supported TB contact tracing in resource-constrained settings. First, digital contact forms demonstrably improve data quality and accelerate diagnosis speed, enabling community health workers to conduct standardized investigations systematically.
Second, addressing implementation barriers is essential: 87% of health systems report limited internet connectivity, while 76% cite insufficient staff training as major obstacles. Data security concerns and inadequate device hardware further complicate deployment across high-burden countries.
Third, successful scaling requires deliberate integration with national TB control programmes and existing health information systems. Policymakers and health planners should prioritize infrastructure investment alongside comprehensive staff training to maximize programme effectiveness and sustainability.
