National sentinel stroke audit 1998-2011

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.
