SPARCtool updated to version 8.1 

version 8.1 release notes (June 2016)

www.sparctool.com 

SPARCtool 

  • added an estimate for “Patient’s annual risk of stroke or TIA with no therapy if they did NOT have AF (for comparison):” based on Mitchell LB, Southern DA, Galbraith D, et al. Prediction of stroke or TIA in patients without atrial fibrillation using CHADS2 and CHA2DS2-VASc scores. Heart. 2014;100(19):1524–1530. doi:10.1136/heartjnl–2013–305303. CHA2DS2-VASc preducts stroke in non-AF patients simiarly well to AF patients. The risk estimates are much lower for non-AF patients, of course. This is added to SPARCtool based on feedback that it is valuable for patients to see how much higher their stroke risk is because of AF vs. without it.
  • made the bleeding bars in the graph less alarmingly red
  • made the legend title for bleeding in the graph shorter
  • added a “Which therapy options to HIDE?” function. You can use this to tailor discussions with patients to the options you consider viable for whatever reason. It applies to the table and the detailed risk estimates. It does NOT affect the bars shown in the graph [I will fix this in the future].
  • added individual stroke and bleeding risk graphs * added ability to hide either or both graphs * moved the renal function warnings into the drug name bars to save space

 

version 8 release notes (June 2016)

SPARCtool

  • removed CHADS2 entirely. Although CHADS2 and CHA2DS2-VASc perform similarly as prediction tools (Olesen JB, et al. BMJ 2011;342:d124–4), it is no more difficult to use the CHA2DS2-VASc criteria and using one or the other simplifies the layout without losing any predictive performance.
  • added a new “Hypertension (SBP>160 mmHg) for HAS-BLED” since the HTN criteria for CHA2DS2-VASc and HAS-BLED are different.
  • fixed the units on SCr to “mcmol/L”
  • removed color fills for a cleaner look
  • fixed the “Age” logic. Now it’s a 3-position radio-button.
  • improved the layout of the “1 in X” statements throughout
  • added a “Reset” button to clear all the settings
  • removed “population average” values from bleeding table and graph wherever a HAS-BLED estimate exists
  • reformatted all the input areas
  • explicit definition of major bleeding
  • warnings for HAS-BLED >6 of no reliable risk data and explicit “>X%” notation for HAS-BLED bleed risks when score is >6.
