Q&A: Transplants at Vidant Medical Center
Posted — UpdatedWRAL Investigates reporter Renee Chou reached out to the five transplant centers in the state for their explanations about the different waiting times and how new rules will impact the wait. Below is her Q&A with Vidant Medical Center:
Geography plays part, and our surgeons utilize well thought out criteria specific to the organs offered. We tailor the criteria to the specific recipient for the best possible patient outcome.
The criteria that Vidant & UNOS include, but are not limited to:
- Donor organ must be compatible blood type with the potential recipient’s blood type
- Tissue Typing Match Quality: a zero antigen mismatch is ideal
- Percent of reactive antibodies (a pre-test to identify what organs will be rejected by the new host despite being ABO compatible. The higher the PRA, the less likely to have a successful crossmatch to determine compatibility).
- Donor age as compared to recipient age
- Size of the donor v. size of the recipient (will the kidney fit? Is the kidney big enough to work for the size of the recipient?)
- Condition of the kidney
- Social/familiar support after surgery for care and follow-up visits
- Donor disease history (known high risk donors such as IV drug abusers only match to those willing to accept a high risk kidney).
Yes, a patient can list at multiple centers. However, the patient must be able to demonstrate to the individual transplant center they can meet their requirements (e.g., able to reach hospital in ___hours). We have found that very few patients opt to list at multiple centers.
As noted above, it is driven by data. (ABO blood group compatible, tissue typing match quality, donor age, body size of donor and recipient, condition of kidney etc.)
Ultimately we do not choose how or when a kidney ends up here at VMC. UNOS (United Network for Organ Sharing) is the contracted agency that handles organ distribution. UNOS has implemented a comprehensive suite of computer driven algorithm’s that computes where the organ should be offered. This utilizes a revised organ allocation system implemented last fall.
Yes, the new organ allocation system was done in an attempt to further improve the equitability of how organs are shared around the country. One of the major benefits of this change is that younger donor organs are shared with younger recipients regardless of geographic location v. going to a recipient who may only have a five year life expectancy. Per UNOS, the organ allocation system is doing what the models predicted. We have not seen a significant change in the impact here at VMC.
It’s still too early to tell. Theoretically, there is not as big a benefit to adding patients to the waiting list to gain time since most patients gain time based on dialysis start date. As to median wait time going up or down…. Yes, it’s too early to tell. We live in an area with high rates of hypertension and diabetes and we know that these are key risk factors for renal impairment or end-stage kidney disease.
Access to care, both pre and post-transplant is critical in the decision-making process. Also, quality outcomes data will paint a very clear picture of how well a center is truly performing. Finally, we have to remember that transplant is both an art and science. For the patient in need of a transplant, he or she will look for the best outcomes data BUT they will also look for how they were treated at a given center. Competent care is expected. At Vidant, we believe that our pre and post patient care are the differentiators.
