SSNAP only changes the core dataset when it is of the highest clinical importance to do so. The evidence base for intra-arterial therapy in treating ischaemic stroke expanded enormously over the 12 months preceding the dataset change with the publication of four major RCTs.
Ensuring that intra-arterial therapy is provided safely and effectively is essential. The questions are based on the standards for providing safe acute ischaemic stroke thrombectomy services published in 2014 by BASP, the ICSWP, British Society of Neuroradiology and Neuroanaesthesia Society for Great Britain and Ireland. These questions are expected to replace the need to provide any other audit data such as SITS.
