The use of donated organs from deceased patients at higher risk of diseases such as HIV and hepatitis has helped reduce the number of patients on transplant waiting lists. And while donated organs are tested for infectious diseases and other conditions that could be transmitted, the risk cannot be completely eliminated.

But the authors say there are wide variations in disclosure to patients among hospitals, including those in the Philadelphia area.

The authors argue that a single national disclosure policy of the risks should be established to allow those on transplant waiting lists to agree up front to accept organs regardless of risk or only those considered low risk for transmittable problems.

"Evidence of compliance with this policy should be required for transplantation programs," the article concludes.
