The refresh of the National Adult Cardiac Surgery Audit including data for operations undertaken between 1st April 2011 and 31st March 2014 is published today (15/09/2015) at http://www.scts.org/modules/surgeons/default.aspx and my NHS https://www.nhs.uk/Service-Search/performance/Consultants. The data is in response to the NHS England transparency agenda and gives activity and risk adjusted mortality rates for all hospitals and surgeons in England and Wales, and hospital level data for Scotland and Northern Ireland. It should be noted that the results reflect activity and mortality rates in the period under scrutiny and may not reflect more contemporaneous results.
The methods for data validation and statistical analysis are complex and have been subjected to extensive external scrutiny.
The 2010-2013 analysis was reviewed by a team led by Professor Nick Black.
The 2011-2014 analysis was reviewed both by a team led by Professor Nick Black and by Professor David Spiegelhalter – Further information on this is available.
The full methods for the NACSA audit (the Strobe Statement) is available on request.
