Effect of an iPod video intervention on consent to donate organs: a randomized trial.

BACKGROUND

The gap between the supply of organs available for transplantation and demand is growing, especially among ethnic groups.

OBJECTIVE

To evaluate the effect of a video designed to address concerns of ethnic groups about organ donation.

DESIGN

Cluster randomized, controlled trial. Randomization was performed by using a random-number table with centralized allocation concealment. Participants and investigators assessing outcomes were not blinded to group assignment. (ClinicalTrials.gov registration number: NCT00870506)

SETTING

Twelve branches of the Ohio Bureau of Motor Vehicles in northeastern Ohio.

PARTICIPANTS

952 participants aged 15 to 66 years.

INTERVENTION

Video (intervention; n = 443) or usual Bureau of Motor Vehicles license practices (control; n = 509).

MEASUREMENTS

The primary outcome was the proportion of participants who provided consent for organ donation on a newly acquired driver's license, learner's permit, or state identification card. Secondary outcomes included willingness to make a living kidney donation to a family member in need and personal beliefs about donation.

RESULTS

More participants who viewed the video consented to donate organs than control participants (84% vs. 72%; difference, 12 percentage points [95% CI, 6 to 17 percentage points]). The video was effective among black participants (76% vs. 54%; difference, 22 percentage points [CI, 9 to 35 percentage points]) and white participants (88% vs. 77%; difference, 11 percentage points [CI, 5 to 15 percentage points]). At the end of the trial, fewer intervention than control participants reported having insufficient information about organ donation (34% vs. 44%; difference, -10 percentage points [CI, -16 to -4 percentage points]), wanting to be buried with all of their organs (14% vs. 25%; difference, -11 percentage points [CI, -16 to -6 percentage points]), and having conflicts with organ donation (7% vs. 11%; difference, -4 percentage points [CI, -8 to -2 percentage points]).

LIMITATION

How the observed increases in consent to donate organs might translate into a greater organ supply in the region is unclear.

CONCLUSION

Exposure to a brief video addressing concerns that ethnic groups have about organ donation just before obtaining a license, permit, or identification card increased consent to donate organs among white and black participants.
