Anticoagulation Choice

A freely available tool for use during the consultation between clinicians and their patients with atrial fibrillation considering preventing strokes using anticoagulation.

SDM tool design

This paper describes the process used to design Anticoagulation Choice as an encounter-based SDM tool:

A practice-based randomized trial of Anticoagulation Choice vs. usual care


In Table 1, for the SNS Inadequate numeracy score the correct count of patients in the intervention arm is 141 (reported 140) out of 448 and for the standard care arm the value of 136 is correct out of 435 encounters.

For Table 2, the following counts were mistakenly omitted. For the clinician type, 4 clinicians were RN out of the 222 clinicians that reported type. For practice type, 26 of the 222 clinician responses were Other (Emergency room, hospitalist, Anticoagulation Clinic, geriatrics, vascular medicine, etc.)

We regret these mistakes introduced in the publication phase.

Scan & Optimization of Decision Aids for Atrial Fibrillation

As part of the formative work towards comparing an encounter SDM tool to a patient decision aid for the same decision, the KER Unit conducted an environmental scan and stakeholder interviews to determine the characteristics that these two forms of decision support should have, and should have in common. This is project funded by a grant to University of Utah and Mayo Clinic through a funding collaboration between American Heart Association and the Patient-Centered Outcomes Research Institute (PCORI) Grant # 18SFRN34110489 to Dr Fagerlin (Center, STEP-UP AF), and Grant # 18SFRN34230142 to Dr Ozanne/(Project, RED-AF).

Report on the environmental scan (PDF) and expert panel review document and minutes as well as patient interviews.
