Blockchain in Healthcare

If African healthcare will experience exponential growth, it is going to be through blockchain technology.

That is not a slogan I picked up. It is the conclusion I keep arriving at, from the ward and from the data.

The problem, stated plainly

A patient arrives at a new hospital and their history does not arrive with them. They repeat the same story. They repeat the same tests. The clinician makes a decision with less than they should have, and the patient pays for the gap in time, money, or outcome.

Across much of the continent this is not an edge case. It is the default.

The record problem is a data problem: fragmentation across institutions that do not exchange information, no shared standard for that exchange, no reliable audit trail, and no meaningful ownership by the patient of their own history.

Why blockchain, specifically

Those four failures map almost exactly onto what distributed ledgers are built to provide.

One record, many custodians. Hospitals, labs and pharmacies that have no reason to trust each other can still agree on a single shared history without any one of them owning it.

A history that cannot be quietly rewritten. Every access and every amendment leaves a trace. In a system where records go missing and notes get altered after the fact, tamper-evidence is not a technicality — it is patient safety.

Consent the patient actually holds. The patient grants and revokes access themselves, rather than requesting their own history from an institution that treats it as property.

Portability by default. A record that lives on shared infrastructure moves with the patient — between hospitals, between states, across borders.

This is the part that makes it worth the effort. Africa is not retrofitting a mature national health IT system the way Europe and North America must. In much of the continent, the infrastructure is still being decided. That is a rare position to be in: the chance to build the right architecture the first time rather than spend a generation migrating away from the wrong one.

What it will not do

Blockchain is not a health system. It does not create records that were never written, train the staff who write them, or supply electricity and connectivity a clinic does not have. Anyone selling it as a cure is selling something.

The honest claim is narrower and still worth making: it fixes the trust and portability layer, which is precisely the layer that fails when a patient crosses an institutional boundary.

The research

I am conducting a systematic review of blockchain-based electronic health records in African healthcare — surveying what has actually been proposed, piloted and evaluated on the continent, rather than what is theoretically possible.

This is work in progress. Findings will be published here once the review is complete.

I write about these ideas as I work through them — what the technology can carry, what it cannot, and what implementation would really demand of an African health system.
