Abstract
versus 19.5, P 0.04). Patients in the PtDA group were also significantly more knowledgeable regarding the risks and benefits associated with each vascular access (mean knowledge score of 3.0/5 (95% confidence intervals (CI) 2.6-3.3) versus 2.0 (95% CI 1.7-2.3, P 0.01). Despite 76.3 % of patients actively selecting their vascular access route of choice in the PtDA group as compared to 39.2% in the control group (P 0.01), there were no significant differences in safety outcomes. CONCLUSION: A vascular access PtDA for eligible patients undergoing coronary angiography procedures significantly improves the patient’s knowledge of their health care options and reduces decisional conflict, without affecting safety outcomes. This study demonstrates the significant benefits of involving eligible patients in the decision process regarding vascular access for coronary angiography procedures.
