Measuring to improve

The Sentinel Stroke National Audit Programme (SSNAP) is a major national healthcare quality improvement programme.  We measure how well stroke care is being delivered in the NHS in England, Wales and Northern Ireland.  We provide timely information to clinicians, commissioners, patients and the public so it can be used to improve the quality of care that is provided to patients.  We have been voted the most effective national clinical audit in the UK every year since 2012.

Our audits

Our clinical audit measures the processes of care provided to stroke patients in inpatient and community settings.  Our organisational audits measure the structure of stroke services in acute hospital settings (acute organisational audit) and  the structure of stroke services in community settings (post-acute organisational audit).  All of our audits measure stroke care against evidence based standards.
