THE CORRIDOR • NHS SPECIAL EDITION

Three Systems. One Patient. Zero Corridors.

NHS Intelligence • May 2026 • What your data looks like from the bed

This edition is not projected through a company. It is projected through a patient.

In April 2026, one patient in Portsmouth had liver disease managed at Queen Alexandra Hospital (PHU), a mental health detention at St James' Hospital (HIOW Healthcare), and GP medications in a third system. Three NHS trusts. Three clinical record systems. Zero real-time integration at the point of clinical decision.

The depot injection was administered without integrating the liver disease. The medication list from the GP was not visible on the ward. Not because clinical staff did not care. Because the systems they were given cannot see each other.

THE HEADLINES

Palantir can see your patient data. Your ward cannot see the ward next door. NHS England confirmed on 12 May that Palantir staff have "unlimited access" to identifiable patient data via the GBP 330 million Federated Data Platform. Meanwhile, only 30% of trusts with EPRs have achieved integrated data flows. A company in Denver can see what the nurse on Maple Ward cannot.

Portsmouth has no modern EPR. PHU is in early procurement for OneEPR - a joint programme with Isle of Wight NHS Trust. No vendor selected. GBP 60 million of frontline digitisation funding was offered, then withdrawn. The trust posted a GBP 12.3 million deficit and is cutting 549 roles to find GBP 39 million in savings. They need to buy a new system with money they do not have.

The trust that holds your mental health records failed to investigate 1,000 deaths. HIOW Healthcare was formed in October 2024 from the merger of Southern Health, Solent NHS Trust, and Isle of Wight transfers. Southern Health's Mazars Report found just 1% of learning disability deaths were investigated. Connor Sparrowhawk drowned in a bath in 2013. The trust was fined GBP 2 million. The merger changes the org chart. It does not automatically unify the data.

THE THREE ROOMS - WHAT YOUR DATA LOOKS LIKE

Room 1: QA Hospital PHU - Acute care	No modern EPR. Legacy patchwork of departmental systems. Bloods, scans, ward notes, discharge summaries. OneEPR in procurement - years from delivery. CQC: Good overall, A&E Requires Improvement.
Room 2: St James' HIOW - Mental health	RiO (The Access Group). Mental health assessments, section paperwork, PICU notes, risk assessments. Community MH rated Requires Improvement - nine regulatory breaches. Maple Ward PICU rated Good.
Room 3: GP Surgery Primary care	EMIS Web or SystmOne. Medications, consultations, chronic disease management. The only place the full medication list lives. Not visible from Room 1 or Room 2 in real time.
The Bridge CHIE - Shared record	Read-only summary viewer. 87 million documents. Orion Health platform. Shows what is pushed to it - if a team pushes data in, and if a clinician knows to look. Not a unified record. A partial window into what the other rooms chose to share.

The pattern: three architecturally incompatible systems, one read-only bridge that depends on voluntary data sharing, and a single patient record via the NHS App not expected until 2028. The clinical staff are not the problem. The corridors between the rooms are.

THE NUMBERS EVERYONE IS TALKING ABOUT

GBP 330M	Palantir Federated Data Platform contract. Unlimited access to identifiable patient data. Greater Manchester is the only ICB refusing to participate. Government exploring early exit - break clause review spring 2027
30%	Trusts with EPRs that have achieved integrated data flows. 93% have an EPR. 70% cannot share data bi-directionally with the trust next door
GBP 4.1B	NHS trust IT spend 2024/25, up 9% YoY. Fastest-growing segments: data, interoperability, and digital front door. The money is being spent - the question is whether it connects anything
GBP 12.4B	Cost of the National Programme for IT. Tried to connect 300,000 GP practices and 300 hospitals with one database. Scrapped. The biggest IT failure in British history. And they are about to try again with Palantir
7.31M	RTT waiting list. Down from peak but still 60% above pre-pandemic. 63.8% seen in A&E within 4 hours. 19.9% waiting over 6 weeks for diagnostics. The system is not coping
1,000+	Deaths at Southern Health (now HIOW Healthcare) that were never investigated. Mazars Report, December 2015. 1% of learning disability deaths were looked into. The consequence of not seeing across the book
3	Patient deaths at 2 acute trusts directly linked to EPR problems (BBC FOI). 126 instances of serious harm across 31 trusts. 200,000+ medical letters from 21 trusts never sent due to IT failures

WHAT'S REALLY GOING ON

The GBP 330M question. Palantir's Federated Data Platform was meant to connect the dots. Instead, Greater Manchester publicly refuses to join. Parliament debated it on 16 April. Medact published a formal briefing on concerns. The government is reviewing the break clause for spring 2027. NHS England confirmed on 12 May that Palantir staff get admin-level unlimited access to identifiable patient data. A company founded by Peter Thiel can see what the ward next door cannot.

The alternative nobody is discussing. The clinical staff already know their systems. The IT teams already maintain them. The data already exists. The only thing missing is the connection between them - and the training to think in joined-up structures rather than departmental silos. That does not cost GBP 330 million. It does not require sending patient data to Denver. It requires teaching the people who already own the systems to connect them. Sovereign by construction.

The merger illusion. HIOW Healthcare merged Southern Health, Solent, and IoW services on 1 October 2024. One trust, 13,000 staff, 2 million people. But merging the org chart does not merge the clinical systems. RiO (mental health) and whatever PHU runs (acute) remain architecturally separate. The merger creates a bigger room but does not build corridors between them.

Digital S136 as proof of concept. Hampshire and Isle of Wight pioneered the country's first Digital Section 136 Monitoring Form - a web-based tool capturing the entire patient journey from police detention to assessment. If they can digitise the Section 136 pathway, they can connect the clinical systems. The capability exists. The architecture does not.

Workforce. Resident doctor strikes in April (6 days, 7-13 April). BMA rejected 4.9% pay offer. Strike mandate extends to August. Mental health nursing vacancy rate: 16.1%. Meanwhile NHS England is being abolished and merged into DHSC by April 2027, with 50% headcount reduction. Who is going to build the corridors when everyone is either on strike, being made redundant, or both?

THE CORRIDOR INDEX - NHS EDITION

Same triangle. Different parameters. You cannot game one without the others catching you.

Cost / Patient Episode

Is the system efficient?

Patient Satisfaction

Do patients feel it?

Staff Survey / Social

Do staff feel it?

Cut staff? Costs fall but staff survey tanks and care suffers. Underfund IT? Saves money but errors rise and patients suffer. Overwork staff? Vacancies rise and the agency bill doubles.

Want your trust's numbers? Produce better public data. Transparency is the product.

PHU ranks 119 out of 124 acute trusts - Segment 4, bottom tier. Good CQC but the league table tells a different story. GSTT sits at rank 10 with 73% of staff recommending it as a place to work and a 3.9 Glassdoor. UCLH leads at 80% recommend. PHU's Glassdoor is 3.6 and falling - down 16% in the last 12 months. Work-life balance: 2.8 out of 5.

NHS trusts are collectively GBP 780 million in deficit. 69% of acute trusts are running a deficit. IT spend hit GBP 4.1 billion, up 9% - but 70% of that spend still does not produce integrated data flows. The money is going in. The corridors are not coming out.

THE TWO LANES

THE PALANTIR LANE

GBP 330 million. Data sent to a platform you cannot see inside. "Unlimited access" for vendor staff. Greater Manchester refuses. Government reviewing exit. Built by a company whose founder said "I no longer believe that freedom and democracy are compatible."

THE GLASS BOX LANE

Train the IT people who already know the systems to connect them. Open standards. Sovereign data - never leaves the trust. Every connection visible, auditable, owned by the NHS. Orders of magnitude less than GBP 330 million. No CLOUD Act exposure.

THE BOTTOM LINE

Nobody needs to buy anything new. The data is already there. The systems are already there. The clinical staff are already there. The IT teams are already there. The only thing missing is the connection between them.

Queen Alexandra has no modern EPR but it has clinicians who know their patients. St James' has RiO but it cannot see the liver disease across the corridor. The GP has the medication list but it stays in the surgery. CHIE exists but it is a window, not a door.

Hampshire already built the country's first Digital Section 136 pathway. The capability to connect is there. The architecture to connect is not. That is not a GBP 330 million problem. It is a thinking problem.

Not bitter. Just disappointed.

The corridor is not a metaphor. It is an architecture decision. And right now, nobody in Portsmouth has made it.

The Corridor - intelligence projected through your world

This special edition demonstrates that the Corridor framework works beyond insurance. Same triangle. Same structure. Different sector. If your organisation has data in rooms that cannot see each other, the shape is the same.
