The HSCT-CHESS Web site provides ready access to accurate information and resources about pediatric HSCT, practical tips, organizational tools, and other supportive services for use during the transplant process. While the Web site is designed primarily for use by the accompanying parent, it also includes some resources for child and adolescent HSCT recipients that the parent may choose to share. In addition to collecting data for later analysis, the Web site tracking system allows for further tailoring of information and support for the user, principally by time post transplant.
