The Star Wars That I Used to Know

SPARC Atrial Fibrillation Stroke & Bleeding Risk calculator updated and mobile-friendly

I've updated my SPARC tool to version 6.0.

What's New?

  1. A mobile-friendly version that I've tested on the iPhone and which should work on most Android phones. Suggest saving the link to your home screen and it will behave like an app.

  2. Some minor updates to both versions such as:

  • Changed the efficacy interpretation of the ROCKET-AF (rivaroxaban) trial to "similar to warfarin". It used to report a HR of 0.79 vs. warfarin (based on the primary non-inferiority anaylsis). However, since the superiority analysis was non-significant in the ITT population, the more appopriate interpretation is that rivaroxaban in similar to warfarin.
  • clarified wording for aspirin+clopidogrel that the major bleeding risk is based on ACTIVE W showing similar bleeding risk to warfarin, hence the HAS-BLED risk can be used, even though HAS-BLED isn't intended for use in a non-anticoagulated patient.
  • minor textual updates

 What's next?

Graphical representations of the stroke and bleeding risk data on the web version. Several users have requested this, which could make it easier to discuss with patients.

Browser-detection so mobile users go direct to the mobile version.
