Ministers pledged that a “life-changing” stroke treatment would be available 24 hours a day, seven days a week, across England from the start of this month. That promise has been broken, with seven specialist centres still unable to offer the procedure around the clock, leaving patients in some regions at risk of severe, avoidable disability.
The treatment, known as mechanical thrombectomy, is a minimally invasive procedure hailed as a game-changer for severe strokes caused by a blocked artery in the brain. Using a catheter threaded from the groin or wrist, doctors can physically remove the clot, restoring blood flow. Its effectiveness is critically time-sensitive, with benefits diminishing by approximately 3.4% for every hour of delay after symptoms begin, and it is most effective within a six-hour window.
Despite its proven impact—around 45% of patients have a chance of regaining independence—access remains a geographical lottery. Seventeen of England’s 24 regional stroke centres do offer thrombectomy at all times. But seven, located in Hull, Middlesbrough, Leeds, Sheffield, Newcastle, Brighton, and Coventry, failed to meet the 1 April deadline set by the government for achieving a 24/7 service.
The staffing crisis behind the delay
The central reason for this shortfall is a profound and persistent shortage of specialist staff. Performing a thrombectomy requires highly trained interventional neuroradiologists, supported by stroke doctors and specialist nurses. Experts estimate that between 142 and 192 operators would be needed to provide 24-hour coverage at all 24 neuroscience centres. As far back as 2016, there were only 83 consultants in England, Wales, and Northern Ireland capable of performing the procedure, far fewer than the 150 then estimated to be needed for UK-wide 24/7 coverage.
This workforce gap has direct human consequences. Dr Sanjeev Nayak, a stroke specialist at Royal Stoke hospital, believes that 10-20% of stroke patients in the UK die or sustain serious disability due to treatment delays linked to staff shortages. “A patient presenting during normal working hours in a well-served area may receive rapid, life-changing treatment, whereas the same patient presenting at night or in a different region may not receive thrombectomy at all,” he said. “This creates a real postcode lottery.”
The geographical inequity is stark. While centres in Coventry and Brighton have arrangements to transfer patients needing overnight treatment to hospitals in Birmingham and London respectively, Yorkshire and the north-east are left with no form of 24/7 service at all.
Missed targets and the cost of inaction
The failure to deliver universal access undermines national health goals. The NHS Long Term Plan aimed for 10% of stroke patients to receive mechanical thrombectomy by 2022, a target that was missed. Current figures show only about 4.3% of stroke patients in England receive the procedure, though this is an increase from previous years. NHS England has since revised the target to 10% by 2029.
This slow rollout persists despite the treatment being highly cost-effective. The NHS spends over £100 million annually on thrombectomy, but it is estimated to save the health service a further £73 million a year by preventing severe disabilities that require lifelong care. A 2020 study estimated the cost of providing the procedure and immediate inpatient care at £10,846 per patient. Stroke is estimated to cost the NHS around £3 billion per year, with an additional £4 billion impact on the economy in lost productivity and care.
Karin Smyth, the NHS minister, confirmed as recently as 23 March that the health service was meant to achieve universal 24/7 access by 1 April. NHS England has made £14 million of extra targeted funding available to the seven struggling areas to support service expansion and staff training, confirmed in February. A spokesperson said achieving round-the-clock access remained a priority and that they were working directly with trusts to improve access “as soon as possible.”
Alexis Kolodziej, deputy chief executive of the Stroke Association, welcomed the investment but said its implementation was “woefully slow” in parts of the country. “The government’s failure to deliver on its promise leaves patients at a significant disadvantage,” she said. The charity advocates for 24/7 access everywhere, calling it a “powerful driver for change” in stroke services.
With over 100,000 people in the UK having a stroke each year—causing 38,000 deaths—the human and economic stakes of improving care are immense. While the overall three-month mortality rate for those undergoing thrombectomy (15.3%) is lower than for those receiving best medical therapy alone (18.9%), the treatment’s primary power is in dramatically reducing severe disability. NHS England’s confirmation that it has not yet fulfilled its ambition means that, for now, a patient’s chance of a life-changing recovery still depends heavily on where and when their stroke occurs.
