Stroke Prevention A.Fib Calculator (SPARC) Updated Again!

I’ve just updated my SPARC tool for calculating your patients’ risk of stroke/thromboembolism and now major bleeding.

I’ve incorporated the now-published results from the ROCKET-AF trial (rivaroxaban) and theARISTOTLE trial (apixaban).  I’ve corrected a few typos and calculation issues.  I’ve added updated references for the above trials, plus a reference to a paper we’ve published recently casting doubt on the utility of the HAS-BLED scoring system.

I would sincerely appreciate any comments or suggestions anyone has about this tool. ploewen@interchange.ubc.ca
