Impact of a Decision Aid on Patient Decision Making in Emergency Department Chest Pain Patients

This study has been completed.

Erik P. Hess, Mayo Clinic Identifier:
First received: February 24, 2010

We are doing a study to assess the impact of including patients in making decision regarding their own medical care in the emergency department. We will randomly assign them to either receive a decision aid or usual care. In doing this, we aim to increase patient satisfaction and safely decrease medical cost.
