Official Title

Vascular Access Options in Coronary Angiogram Procedures: A Patient Decision Aid Randomized Controlled Trial

Status

Completed

Overview

to evaluate the effectiveness of an evidence-based PtDA compared with usual care in patients eligible for radial and femoral artery access.

Study Design

single-center, nonblinded, randomized controlled trial

Primary Endpoint

The primary outcome, decisional conflict, was assessed using the validated decisional conflict scale. One hundred fifty patients were randomized (vascular access PtDA=76 versus usual care=74). The intervention group had a significantly reduced decisional conflict scale compared with control (unadjusted 14.8 versus 19.5, P=0.04) and were significantly more knowledgeable regarding risks/benefits associated with each vascular access (mean knowledge score 3/5 (95% confidence interval, 2.6 to 3.3) versus 2/5 (95% confidence interval, 1.7 to 2.3, P<0.01). PtDA patients had better informed value congruence with their vascular access received (47.3% versus 25.7%, P<0.01).
