RT Journal Article SR Electronic T1 National Sentinel Stroke Audit 1998–2011 JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 444 OP 448 DO 10.7861/clinmedicine.13-5-444 VO 13 IS 5 A1 Geoffrey Cloud A1 Alex Hoffman A1 Anthony Rudd on behalf of the Intercollegiate Stroke Working Party YR 2013 UL http://www.rcpjournals.org/content/13/5/444.abstract AB Stroke is a common and devastating disease and, until very recently, was largely unrecognised as a ­preventable or treatable condition. Between 1998 and 2010, the National Sentinel Stroke Audit (NSSA) achieved 100% voluntary participation, collecting data on more than 60,000 patients from stroke services within England, Wales and Northern Ireland and becoming a benchmark for hospital stroke services. In this way it has informed stroke improvement at the local, regional and national levels and has overseen a radical change in stroke care within the NHS. This article describes the achievements of the NSSA and the ­lessons learned.
