David Ranson Medical Director DTBV

David Ranson, Medical Director of the Donor Tissue Bank of Victoria

As Medical Director of the DTBV, David Ranson works with the Head of the DTBV and the medical and scientific staff reviewing the medical history of donors and the test results of retrieved tissue to maximise tissue safety for recipients and their health care providers. Donor tissues processed through accredited tissue banks have never been safer. But it is important that the scientific and medical protocols, and donor selection criteria, are regularly reviewed and subject to operational audit as well as external accreditation so as to maintain and improve this level of safety. David works directly with the DTBV’s scientific and nursing staff and liaises with the forensic pathologists at the Victorian Institute of Forensic Medicine to ensure the best possible outcomes for patients receiving these tissue transplants.

Susan Dickie, Nurse Manager, DTBV

Susan Dickie, Nurse Manager
Susan Dickie manages the team of Tissue Donation Nurse Specialists who work at the DTBV. Their role is to speak with the families of the recently deceased to offer them the opportunity to consider tissue donation. The Tissue Donation Nurse Specialists provide families with information about the tissue donation process, answer any questions they may have and support them in making an informed choice about the possibility of donation. They also explain what tissues can be donated and the difference tissue grafts can make to the health and recovery of patients in need. Since tissue donation is only possible within very short time frames, this initial conversation usually takes place only a few short hours after families have been notified of the death of their loved one. Making a decision about donation at such a tragic time can be extremely difficult but knowing a person’s wishes in relation to donation and having previously discussed donation can help families with their decision making.
