Rhode Island has state legislation around cord blood education that follows the Institute of Medicine guidelines and mandates/encourages physicians to educate expectant parents about ALL forms of cord blood banking. The Rhode Island bill was enacted 27 June 2008 and became effective 27 June 2008.
- Are related donors better for transplants?
The overall answer is yes, but this is a complex topic.
The two important measures of patient outcome are: long-term survival, and the impact on quality of life from graft-versus-host disease (GvHD). Sibling donors tend to trigger less GvHD. Also, sibling donors are available faster than searching for an unrelated donor, and patients have better survival when they go to transplant faster after diagnosis.
The exact comparison of outcome between sibling or unrelated donor varies with the patient diagnosis. The NMDP website has a page on this, with numerous references. For many cancers the outcomes are comparable, although sibling donors have a slight edge. The largest study was by Weisdorf et al. 2002, for over 2900 patients with CML leukemia. When correcting for all other factors, the survival with sibling donor vs unrelated donor was 68% vs. 61%. Sibling donors show a significant improvement for pediatric cord blood transplants of hereditary disorders. The European Blood and Marrow Transplantation Group (EBMT) reported 3 year survival rates of 95% from a sibling donor vs. 61% from an unrelated donor.

- How is education from the Parent's Guide to Cord Blood unique?
- We are the only organization in the United States providing cord blood education materials that offer balanced information about both donation and family storage, and are approved by an Advisory Panel of leading Scientists and Medical Doctors.
- What is delayed cord clamping?
Some people feel that the blood in the umbilical cord should be allowed to flow into the baby and that the cord should not be clamped while it is still pulsing. Medical studies have shown that, particularly in parts of the world with poor infant health care, delayed cord clamping can help protect the baby from anemia (low blood counts) during the first 6 months of life. However, a prolonged delay will allow the blood in the cord to clot, and the opportunity to collect the blood for stem cells will be lost. Therefore, if clamping is delayed, it should not be more than two minutes.
