A single hospital generates 50 petabytes of data a year.
Printed, the stack reaches the moon and back, twice. Almost none of it is used.
The NHS spends £8 billion a year on medical equipment and consumables (NAO, 2024). Across every study from 2014 to 2025, 8 to 20% of surgical supply cost per case is opened and never used. The most common reason: anticipating what the surgeon might need.
That number already lives in your systems. Your theatre system saw it. Your preference cards carry it. Your procurement records know it. None of them connect.
That is not a problem. That is a goldmine with a locked door.
Lord Carter said it in 2016: most hospitals do not know what they buy, how much they buy, or what they pay. Not because the data does not exist. Because it has never been given a shared model of itself.
That model is an ontology. A jigsaw scattered across four boxes with no picture on the lid. The ontology is the picture on the lid. It adds no new data. It shows how everything you already have fits together.
The proof: when one hospital reconciled its preference card data, colorectal surgery waste fell 55% (JAMA Surgery, 2025). No new suppliers. No renegotiated prices. Just the data, connected.
Three spots. No IT project. A CSV is enough. One week later: your supply chain ontology and a named map of where your surgical spend leaks, by surgeon, by procedure, by item.
No fee.
