OBJECTIVES: Vascular interventions are becoming increasingly complex; as procedures become more complex, patient understanding of their treatments can become more difficult. This study aims to evaluate the utility of multimedia presentations (MMP) on an Apple® iPad computer for patient understanding of vascular interventions.

METHODS: Patients undergoing endovascular aneurysm repair (EVAR), peripheral angioplasty, Hickman catheter and peripherally inserted central catheter (PICC) line insertion were randomized into a control group receiving traditional verbal consent, or a MMP group that were shown a 2-minute simplified video of their procedure in addition to the traditional verbal consent. After obtaining consent, all patients completed a questionnaire assessing comprehension of the procedure and satisfaction with the consent process.

RESULTS: Eighty patients were recruited for this study, 20 for each procedure. Patients reported the utility of the MMP as an average of 4.8 on a 5-point Likert scale, with 5 being “very helpful” in understanding the procedure. The MMP was shown to improve patient comprehension of certain procedures, with angioplasty patients in the MMP group answering more questions correctly during assessment of comprehension (p=0.002).

CONCLUSIONS: This study has shown that patients find MMP during the consent process to be very helpful in understanding vascular interventions and that patients receiving certain vascular interventions have improved comprehension of their procedures when shown an MMP during the consent process. Given the rapid rate of innovation in vascular surgery, the use of an MMP to help patients understand new and complex procedures would be beneficial in the future care of patients undergoing vascular interventions.
