Connected devices, disconnected data: what it takes to close the gap

In distributed health programs, the weakest point in the data chain is rarely the laboratory or the clinic. It is the gap between a diagnostic result and the national system that is supposed to receive it. This article describes how BAO Systems closed that gap for a major global health program, replacing a fragile, manual-dependent architecture with a modern connectivity infrastructure spanning seven African countries and the United States.

Across multi-country, high-volume, and low-resource settings, critical diagnostic data routinely fails to reach national health information infrastructure. While point-of-care (PoC) testing instruments successfully detect diseases in peripheral healthcare facilities, test results, device telemetry, and quality indicators frequently remain trapped on the physical units. Traditional data collection relies heavily on manual entry or legacy platforms, making connectivity fragile and creating delays where results are captured on paper and program decisions are made on incomplete data. This fragmentation creates significant program blind spots. Without an integrated architecture, public health authorities cannot view disease hotspots, monitor stock levels, or track device utilization in real time, causing investments in downstream analytics to consistently underperform.

BAO Systems designed and executed a platform modernization strategy to transition distributed point-of-care connectivity infrastructure to a modern, scalable cloud solution. The architecture establishes a secure, cloud-based environment compliant with data privacy regulations for hosting sensitive health data.

Key components of the implementation included:

• Infrastructure migration: Provisioned global and individual country-specific cloud environments built on flexible analytics platforms to replace legacy backend architectures.
• Custom API and gateway integration: Developed custom APIs to ingest data transmissions from over 2,000 connected devices across seven African countries and the United States, repurposing existing edge gateways to transfer multi-protocol data seamlessly.
• Hardened field connectivity: Deployed purpose-built hardware with a store-and-forward architecture to buffer results locally during network outages, automatically retrying transmissions once connectivity was restored to prevent data loss.
• Remote fleet management: Implemented remote gateway administration capabilities, allowing administrators to push firmware updates, validate device geolocations, and execute diagnostic commands across networked sites without requiring physical access.

The modernized infrastructure provides a resilient data pipeline, ensuring critical PoC health data remains accessible and actionable at national and multi-country levels.

• Operational continuity: The migration delivered a smooth transition with zero loss of historical data, validated rigorously before the legacy platform was decommissioned.
• Enhanced decision-making: Validated dashboards visualize device utilization, positivity rates, and testing trends in real time, giving health authorities immediate visibility into disease hotspots.
• Supply chain efficiency: Robust inventory tracking workflows monitor stock consumption by facility, allowing managers to forecast demand accurately and reallocate supplies based on expiration dates to prevent front-line stockouts.

BAO Systems continues to extend ConneX capabilities across programs working in HIV, TB, and broader diagnostics. Organizations looking to close the gap between point-of-care data and national health systems can contact us to discuss how the platform can be configured for their program environment.
