Nigeria’s digital health ecosystem is expanding, with startups, pilot projects, and digital tools attempting to address gaps in healthcare delivery. Yet adoption and scale across hospitals and clinics remain uneven. Beyond funding and infrastructure constraints, the healthcare system still operates with fragmented clinical records, limited datasets, and weak interoperability across facilities.
This fragmentation is not just an operational limitation. It defines the boundaries of what healthtech startups can realistically build, particularly in data-dependent areas like artificial intelligence, diagnostics, and care coordination.
Innovation Built Around Fragmentation
When MedTech Africa began developing AI systems for preventive cardiovascular care, it encountered a core constraint in the healthcare system: the scarcity of large, structured local datasets.
In an interview with TechCabal Insights, the founder, Nelson Igbiriki, explained that early partnerships with health authorities and outreach campaigns only yielded usable patient data for limited periods, insufficient for training reliable predictive models.
To fill this gap, the company partnered with Toku University Teaching Hospital in Japan, where it trained its model on historical datasets before recalibrating it using limited African data, simulated datasets, and WHO-informed health frameworks.
This reflects a broader reality across Nigeria’s healthtech ecosystem. In the absence of shared health infrastructure, startups often rely on external or synthetic datasets to build functional systems.
For AI-driven healthcare tools, the constraint is particularly significant. These systems depend on large volumes of high-quality longitudinal data, but Nigeria’s healthcare system remains fragmented, with incomplete patient histories and disconnected databases.
In MedTech Africa’s case, the company supplemented limited Nigerian data with international datasets and simulated local patterns to achieve, according to the founder, roughly 85% model accuracy.

Why Interoperability Matters
The fragmentation problem extends beyond AI development. In many Nigerian healthcare systems, clinicians face significant challenges accessing unified patient histories across healthcare facilities due to fragmented records and weak interoperability between hospitals and other care providers.
This often results in duplicated tests, missed referrals, inconsistent treatment monitoring, and weak continuity of care, particularly for chronic diseases that require long-term follow-up.
Telemedicine has made these gaps even more visible. Remote consultations become significantly less effective when providers cannot access previous diagnoses, prescriptions, laboratory results, or referral histories. As a result, many healthtech startups are increasingly prioritising interoperability infrastructure, EMR systems, and patient management tools rather than focusing exclusively on AI products.
Svengen Health, a diabetes management startup, has encountered similar challenges. In an interview with TechCabal Insights, the co-founder, Uchenna Onyeachom, reported that the company’s treatment algorithms currently rely on commercially available datasets focused on African and minority Black populations because validated Nigerian clinical datasets remain difficult to access. Although the platform was designed for interoperability, integrating with existing EMR systems has proven difficult because many hospitals still operate incompatible legacy infrastructure.
The Public Health Data Gap
The lack of unified healthcare data is also affecting public health planning. Ayokunle Omoniyi, founder of Melon, a data-collection startup, told TechCabal Insights that the company frequently encounters major inconsistencies while mapping healthcare facilities across Nigeria.
According to Omoniyi, the country still lacks a reliable central repository for healthcare data, including accurate registries for many Primary Healthcare Centres. To address these gaps, Melon relies heavily on primary data collection via trained field agents, geotagging systems, and manual verification processes.
The company is also building AI layers intended to organise fragmented datasets and identify healthcare patterns from large volumes of manually collected information.
The Infrastructure Problem Behind Nigeria’s Healthtech
The underlying challenge is not simply technological. Hospitals often operate independently, with limited incentives to standardise or share patient records beyond their own facilities. Privacy concerns, procurement fragmentation, inconsistent regulations, and uneven digital maturity further complicate interoperability across healthcare systems.
Ultimately, Nigeria’s digital health ecosystem is not suffering from a shortage of innovation. It is struggling with a shortage of shared infrastructure that allows innovation to scale cohesively.
Until interoperable health data systems exist at scale, many startups will continue building around fragmentation rather than beyond it. And while AI remains one of the most visible areas of healthtech investment, its long-term effectiveness may depend less on algorithmic sophistication and more on whether Nigeria’s healthcare system can build the connected data foundations modern digital healthcare requires.
