Walk through the back corridors of most acute hospitals in England and you will still find trolleys of buff folders parked outside records offices, waiting to be reshelved, retrieved, or driven to a warehouse on an industrial estate somewhere outside the city. This is not a relic. NHS trusts spend close to a quarter of a billion pounds a year keeping these archives functioning, roughly three quarters of it on space within hospitals themselves and the rest on commercial storage firms that charge by the box and the mile. Over five years the bill runs past a billion pounds. Exactly none of this information is new. What has changed is the excuse for it.

For a decade the official answer to paper has been the electronic patient record, and the government has treated its rollout as a solvable engineering problem with a fixed end date. That date was March of this year. The Frontline Digitisation Programme was meant to bring every trust to a baseline standard of digital capability. As the deadline approached, internal assessment put barely more than half of trusts on track to meet it, with an eventual forecast of around seventy per cent reaching the required standard, well short of the universal coverage promised when the programme launched. A handful of ministerial "tiger teams" have been dispatched to help the stragglers, which is itself a quiet admission that procurement and integration inside the NHS remain harder than Whitehall likes to say out loud.

What the paper storage figures reveal, and what should worry anyone running a trust finance committee, is that digitisation and paper reliance are not actually opposites. Some of the most digitally advanced hospitals in the country are still paying heavily to store physical files, because clinical teams routinely print what the software cannot reliably share, and because decades of historic case notes carry medico-legal retention requirements that no software migration project has yet resolved. The NHS is not choosing between an old system and a new one. It is running both, badly, and paying for the overlap.

That overlap is no longer just expensive. It is becoming dangerous. Trusts are now spending an estimated £13.5m this year correcting errors introduced during EPR data migration, records duplicated, referrals routed to the wrong place, patient timelines fractured across incompatible systems. One recent case saw a young child given repeated incorrect doses of a blood-thinning drug after an electronic prescribing system failed to flag the error, an incident directly linked by reviewers to poor governance and inadequate staff involvement during rollout. This is the sharper version of the paper problem. A missing paper file causes delay. A corrupted digital one may be harmful and appear more reliable than it actually is.

For NHS leaders the lesson is uncomfortable but specific. Hitting a coverage percentage on an EPR contract has been treated politically as the finish line, when the genuinely costly and clinically risky work, migrating, cleaning, and reconciling decades of legacy data, only begins once the software is switched on. For policymakers and the Treasury, the £2bn allocated to digitisation was framed as money that would end reliance on paper. It has instead bought partial coverage and a new category of expense in fixing what that partial coverage broke. Life sciences and health tech suppliers selling into this market should expect procurement to tilt toward data migration and interoperability tools rather than fresh EPR licences, since that is where the unfunded risk now sits.

None of this argues for abandoning digitisation, and the report's own figures make clear that leaving records on paper indefinitely is not a serious alternative either. But a health service that has spent a decade chasing a single deadline for going digital might now ask a more useful question: not when trusts will finish switching systems, but who is accountable for the years in between, when patients are exposed to both sets of failures at once.
