NHS England publishes corridor care data as backlogs rise
New data quantifying daily corridor care incidents highlights the scale of patient crowding, alongside persistent failures to meet elective and cancer targets.
From May 2026 NHS England began publishing daily counts of patients forced to wait in corridors, a move that shines a stark light on backlogs that have been swelling for years. The new data – 2,241 corridor‑care episodes per day in emergency departments and 669 outside them – offers the first quantitative glimpse of a crisis that patients, clinicians and policymakers have warned about since the pandemic.
Why the corridor‑care figures matter now
The definition released alongside the data states that anyone who spends at least 45 minutes in a clinically inappropriate area of an emergency department or general and acute ward has experienced corridor care. By turning a previously anecdotal problem into a measurable metric, NHS England can now track the scale of the issue, assess the impact of any interventions, and, crucially, hold trusts accountable for breaches of patient‑centred standards.
Media additions
“The data collection has significant limitations and likely underestimates the true scale,” notes the British Medical Association’s analysis of the same release Bma discussion. Nonetheless, the figures provide a tangible benchmark for a problem that has been described as “deepening” and “to the detriment of patient care, privacy and dignity”.
Backlogs across the system
Corridor care is only one symptom of a broader backlog that stretches back to the early days of COVID‑19. Prior to the pandemic, February 2020 waiting lists already held more than 4.43 million cases for consultant‑led care, according to a separate analysis by npifund. The pandemic‑induced suspension of non‑urgent services caused an initial dip in new referrals, but the queue has since surged, leaving millions still waiting for treatment.
Monthly figures from the same source show that the elective‑care recovery plan’s goal to clear waits longer than 65 weeks by March 2024 has been missed and the longer‑running target that 92% of patients should receive treatment within 18 weeks of referral has not been met since September 2015. The most recent numbers from April 2026 (Bma) reveal that 65 % of patients met the 18‑week elective standard, still short of the interim target of 70 % for March 2027.
Both the BMA and npifund stress that the “hidden backlog” – patients who have not yet presented or whose referrals were cancelled – remains an unknown quantity, further complicating any attempt to gauge the true scale of demand.
Cancer pathways still lagging
Despite the changes in the cancer care targets, services continue to operate well below operational standards. BMA data for April 2026 shows the proportion of patients told they have cancer within four weeks (28-days) of an urgent referral fell from 79.4 % to 77.6 %, missing the 80 % operational target. First‑treatment within one month slipped from 92.8 % to 91.9 %, and within two months from 72.8 % to 70.0 %, well below the 85 % standard and the March 2026 ambition of 75 % performance.
Similarly, npifund reports that in January 2024 the 28‑day target was 70.9 % (down from 74.2 % in December 2023) and the two‑month target was 62.3 %, both trailing operational goals. These parallel declines illustrate that, despite different data windows, cancer pathways are under sustained pressure.
Emergency department pressures
Emergency department (A&E) performance has also deteriorated. BMA figures note that 75.7 % of A&E attendances were processed within four hours in May 2026, down from 76.9 % the month before and below the current operational target of 78 %. The same month saw 1.56 million people waiting more than four hours in A&E, while the number of patients waiting over 12 hours for an emergency admission rose to about 50,000 – a 121‑fold increase compared with May 2019.
Npifund records a slightly different trend for early 2024, with 70.9 % of A&E patients seen within four hours in February 2024, a modest rise from 70.3 % in January 2024, yet still far short of the 76 % target for March 2024. Over the twelve‑month period ending February 2024, approximately 1.59 million people waited more than four hours.
All sources agree that “general and acute bed occupancy has consistently been at over 90 % since September 2021”, a key factor behind prolonged stays and the corridor‑care surge.
Private‑sector capacity – a contested remedy
The BMA, npifund and Medi Recruit all describe the government's reliance on private‑sector block‑booking to alleviate pressure. While block‑booking has added facilities, the same reports note that it has not solved workforce shortages because “the NHS and the private sector largely draw on the same pool of doctors”. A BMA survey cited by npifund found that 60 % of private‑practice doctors surveyed were unable to provide care under the block‑booking arrangements, underscoring the limited impact of this strategy.
What the data tells us – a quick reference
- Corridor care (May 2026): 2,241 ED episodes per day; 669 non‑ED episodes per day.
- Elective‑care target (April 2026): 65 % met 18‑week standard (goal 70 % by March 2027).
- Cancer 28‑day referral target (April 2026): 77.6 % (target 80 %).
- A&E four‑hour performance (May 2026): 75.7 % (target 78 %).
- Patients waiting >12 hours for admission (May 2026): 50,000 (121 × May 2019).
- Unsuccessful GP referrals (Nov 2021): 401,115 (up from 238,859 in Feb 2020).
Timeline of recent developments
| Date | Event |
|---|---|
| February 2020 | Baseline waiting list of 4.43 million consultant‑led cases (npifund). |
| October 2023 | Government announces “up to 400,000 patients waiting over 40 weeks” may be offered travel to another hospital (npifund, Medi Recruit). |
| May 2026 | Corridor‑care episode counts reported; A&E four‑hour performance dips to 75.7 % (BMA). |
What to watch next
The next set of corridor‑care data is due in June 2026, which will indicate whether the daily episode counts stabilize, rise or fall. At the same time, the government’s “elective care recovery plan” aims to restore the 92 % constitutional standard by March 2029. Progress will be tracked against the interim 65 % target for March 2026 and the 70 % target for March 2027, both cited by the BMA.
Finally, the private‑sector capacity debate is likely to resurface as the NHS prepares its next block‑booking round. Both the BMA and Medi Recruit warn that without extra staff, “additional capacity may be less than it initially appears”. Stakeholders will be watching the forthcoming Treasury statements on NHS funding, especially the call for an extra £7 billion on top of the previously announced £10 billion.
All eyes are now on whether the new corridor‑care metrics will translate into policy change, or simply become another set of numbers in a system already strained by backlogs, workforce shortages and periodic industrial action.
