England did not move as one system this year

Across the acute sector, elective waiting times improved almost everywhere, urgent care held flat as a national average while most individual trusts slipped, and diagnostics split the country in two. Here is who moved furthest in each direction, and, where their own board papers say so, what they did about it.

01The national picture

Averages hide the story. On every measure below, the gap between the trusts moving fastest and those going backwards is far wider than the national shift, which is why a single headline figure tells a chief executive almost nothing about their own position.

Referral to treatment
+3.8 pp
median change, 118 acute trusts
The closest thing here to a national success. Only 9 of 118 acute providers went backwards at all, and the largest single fall was 3.9 points.
A&E four hours
-0.3 pp
median change, 120 acute trusts
The flat median is misleading. 70 of 120 providers went backwards, and the national figure holds up only because a smaller number gained heavily.
Diagnostics six weeks
+0.5 pp
median change, 97 acute trusts
Genuinely two nations: 46 of 97 lost ground while others gained thirty points.
Cancer 62 days
+1.1 pp
median change, 115 acute trusts
A slight national gain covering movement both ways: 42 of 115 properly sized services went backwards.

Read the spread, not the median. The two measures where the country genuinely diverged are A&E and diagnostics, and in both cases a national headline of roughly no change is the arithmetic result of large improvements at some trusts cancelling out large deteriorations at others. A board comparing itself to the national figure on either measure learns nothing about whether it is winning or losing.

02Who improved, and what they say they did

The interesting question is never who is top of a table. It is what the movers actually changed, and whether that is repeatable somewhere else. For three of the largest improvements this year, the trust's own board papers answer that in their own words.

King's College Hospital NHS Foundation Trust
Diagnostics waiting six weeks or more: 50.3% to 18.6%, a gain of 31.6 points, on a list of about 26,200 patients
51.6%17.8%Jun 2025Jun 2026
43% of the DM01 6-week backlog sits within NOUS and Echo modalities. Current demand exceeds Trust Capacity for the key modality of cardiac echo. SEL ICB Funding secured to support Insourcing initiative to reduce backlog in cardiac echo until end of March. Currently no administrative team regularly validating the full DM01 waiting list.

Radiology remains the primary dependency, with actions focused on IR scheduling, vetting turnaround, and cross-site reporting. 14 key clinical posts across Urology, Breast, and Radiology now recruited or in final shortlisting.

An accuracy check worth making. That same May board paper reports DM01 performance improving "for the seventh consecutive month this year from 24.58% in February to 19.37% in March". Calculated independently from the national diagnostics return, we hold 24.6% and 19.4% for those months. The trust's own reporting and the national data agree.
The Princess Alexandra Hospital NHS Trust
Patients waiting under 18 weeks: 52.0% to 66.9%, a gain of 15.0 points, second largest in England
68.7%51.1%Jun 2025Jun 2026
Performance against the incomplete 18-week Referral to Treatment (RTT) standard improved significantly during the year, with the Trust exceeding its internal target in March 2026 by achieving 64.1%. This improvement was supported by additional capacity, closer working with community and primary care partners, and strengthened waiting list validation to ensure accurate recording and prioritisation of patients.

Again, the figures reconcile. The trust reports achieving 64.1% in March 2026. The national return gives 64.1% for the same month.
The Shrewsbury and Telford Hospital NHS Trust
Patients waiting under 18 weeks: 56.7% to 69.6%, a gain of 12.9 points
The use of insourcing for USS and MRI is also proving successful, with DM01 continuing to improve towards the target of 99%. Ongoing recruitment is taking place for radiologists, radiographers and sonographers. Referral to Treatment (RTT): The Trust is ahead of plan on all RTT metrics.

The pattern across the improvers

Read together, three accounts written independently of each other converge on the same four moves: find the two or three modalities or specialties actually holding the backlog, buy short term external capacity while recruiting substantively behind it, validate the waiting list so the numbers describe real patients, and hold it in the board's line of sight month after month. None of that is a technology purchase, and none of it is quick.

03Where it went backwards

This half of the analysis needs more care than the first, for a straightforward reason. Boards document improvement in detail and rarely document decline, so for the trusts below we have the movement but not, in their own words, the cause. We publish the numbers and decline to speculate about the reasons.

A note on referral to treatment

There is no meaningful table of RTT deteriorations to publish this year. In the acute cohort the worst one year change was 3.9 points against a median gain of 3.8. Elective access is the one measure here where the national programme is visible in nearly every provider's numbers.

Improvement is not free

Gateshead Health cut its diagnostics six week breaches by 18.2 points while its cancer 62 day performance fell by 9.4 points. Royal United Hospitals Bath improved on both referral to treatment and diagnostics. The same lever, insourced diagnostic capacity, appears in both stories, which is a reminder that capacity moved into one pathway comes from somewhere.

05What we did not publish, and why

A league table is easy. A defensible league table means throwing away most of what the raw data offers. These are the screens applied before any trust was named above, with the specific cases each one caught.

Cohorts too small to rank
On a naive ranking, the largest cancer improvement in England belongs to a specialist heart and lung centre treating about 17 cancer patients a month, and the worst deterioration to a specialist orthopaedic hospital treating about 10. At those volumes a handful of patients moves the percentage by tens of points. Both were excluded, along with every provider below 50 cancer patients a month.
Months that are partial returns
A percentage is only as good as the denominator underneath it. One trust published cancer performance of 26.9% in a month where it recorded just 6 treated patients against a typical 112, and two further months where the count was absent altogether. Those three figures alone were enough to manufacture a 13.9 point deterioration and would have made it the worst cancer performer in England. Read across its complete months, the trust is close to flat.
Changes of scope, not of performance
Fifty six providers were removed from the diagnostics ranking. Some had genuinely incomplete returns; others saw their diagnostic waiting list change by more than 40% in a year, in one case falling 81% and in another rising 83%. A percentage calculated on a list that has been redefined is not a performance comparison.
Baseline artefacts
One trust shows a 28.9 point fall in A&E performance, the largest in the country. Its monthly series climbed from 51% in January 2025 to a peak above 86% that summer, then returned to the low fifties. Measured from the peak it is a collapse; measured across the whole series it is roughly back where it started.
Unlike compared with unlike
Mental health and community providers report referral to treatment against different pathways and service models. Thirty three providers were held out of the referral to treatment cohort on that basis, and are better compared with each other.
Zero that means "not supplied"
Some national returns record an unsupplied figure as a zero rather than a blank. On the ambulance call answering measure, 111 of 396 published rows were zeros of that kind, and taken literally they would rank a service that filed nothing as the best in England on a lower is better measure.
Single months
Every change here compares three month averages a year apart rather than one month against another, so that a single bad month or a seasonal spike cannot create or erase an improvement.

06Why this is hard to do by hand

Every number in this report comes from data any organisation can download. The work is not in obtaining it. It is in knowing that a 40% swing in a denominator means a service was reconfigured, that a zero can mean silence rather than excellence, that a specialist centre's percentages are not comparable with a district general hospital's, and that the reason behind a number usually sits in a PDF on a trust's website rather than in the statistical return.

That is what NHS Performance Intelligence does continuously: it holds the national returns for every trust with the screens above applied, benchmarks each organisation against genuinely comparable peers rather than a national average, and links improvements to what the improving trusts said they did, quoted and sourced.
