Implementing mHealth Interventions in a Resource-Constrained Setting: Case Study From Uganda

Area of Science:

• Public Health
• Health Informatics
• Implementation Science

Background:

• Mobile health (mHealth) interventions are increasingly adopted in low-income countries.
• Existing research often neglects the practical implementation challenges of mHealth interventions, particularly concerning design and technology.

Purpose of the Study:

• To identify and characterize the implementation challenges of a complex mobile health (mHealth) intervention in Uganda.
• To analyze barriers encountered during the deployment of a tuberculosis (TB) contact investigation mHealth tool.

Main Methods:

• A customized mobile survey application was used for a randomized controlled trial on TB contact investigation.
• Digital fingerprinting and automated SMS were incorporated; implementation challenges were documented through site reports and calls.
• Challenges were systematically classified using the Consolidated Framework for Implementation Research (CFIR).

Main Results:

• Key challenges were identified within intervention characteristics, inner setting, and implementer characteristics.
• Limited app adaptability due to software/hardware constraints and intervention complexity hindered implementation.
• Community health worker (CHW) trust in technology decreased after initial failures, impacting usage; complex data structures complicated management and feedback.

Conclusions:

• mHealth interventions can enhance public health delivery but are susceptible to implementation barriers in low-resource settings.
• Lack of adaptability, complexity, declining user trust, and poor feedback systems can undermine mHealth effectiveness.
• Successful implementation necessitates adapting to local resources, prioritizing end-user feedback, and optimizing data management.
