Increasing family consent for organ donation: findings and challenges.

There is a growing disparity between the number of organs and tissues needed for transplantation and the number available for donation. As a result, thousands of people die every year while waiting for a transplant. Much of the shortage can be explained by the failure of families to consent to donation. This paper reviews the research that has been conducted to elucidate reasons why families deny consent. This research, together with theoretically motivated research in the areas of persuasion and behavior change, can be used to inform the design of educational and promotional campaigns and to guide policy decisions.
