Sentinel Stroke National Audit Programme (SSNAP)

The Sentinel Stroke National Audit Programme (SSNAP) is a major national healthcare quality improvement programme based in the School of Life Course and Population Sciences at King’s College London. SSNAP measures the quality and organisation of stroke care in the NHS and is the single source of stroke data in England, Wales, and Northern Ireland.

SSNAP measures both the processes of care (clinical audit) provided to stroke patients, as well as the structure of stroke services (organisational audit) against evidence based standards, including the 2016 National Clinical Guideline for Stroke. The overall aim of SSNAP is to provide timely information to clinicians, commissioners, patients, and the public on how well stroke care is being delivered so it can be used as a tool to improve the quality of care that is provided to patients.



The aims of the SSNAP clinical audit are:

  • to benchmark services regionally and nationally
  • to monitor progress against a background of organisational change to stroke services and more generally in the NHS
  • to support clinicians in identifying where improvements are needed, planning for and lobbying for change and celebrating success
  • to empower patients to ask searching questions
