A stroke is a medical emergency: call 999 if you notice signs such as a face drooping on one side, weakness in one arm or slurred speech. Treatment in the first hours may include medicine to dissolve a blood clot (thrombolysis) or a procedure to remove it (thrombectomy).
In London, ambulances take people with a suspected stroke to a hyperacute stroke unit (HASU) for the first days, then to a stroke unit closer to home. The Sentinel Stroke National Audit Programme (SSNAP) gives every team a level from A to E each quarter, based on how well it meets national standards.

How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Volume bands. Cut points are the lower quartile, median and upper quartile of all 172 stroke teams in the SSNAP January to March 2026 results in the published table, rounded. So about a quarter of stroke teams in the SSNAP January to March 2026 results fall in each band. The exact number is shown under the band.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. Volumes and outcomes here are for each hospital or team, but waiting times and the CQC inpatient survey are for the whole trust.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
