Patient Decision Aids to Engage Adults in Treatment or Screening Decisions.

CLINICAL QUESTION: Are patient decision aids (PtDAs) associated with (1) improved decision quality defined as a decision informed by the evidence and a value-based decision; (2) improved decision-making processes defined as feeling informed, defining clear values related to the decision, and active participation in making the decision; and (3) better patient and health system outcomes compared with either usual care or a non-PtDA intervention? BOTTOM LINE: Patient decision aids are associated with improved decision quality and decision-making processes without worse patient or health system outcomes.
