The CTS statistics are the result of the selfless efforts of several thousand physicians, surgeons, scientists, nurses, technicians, data managers, and other personnel working at the participating transplant centers. Each one of these individuals has contributed valuable information and deserves credit for having taken an active part in this project. If you are working at a transplant center that is not participating in the CTS, please consider contributing to the CTS in the future. The strength of the CTS relies on recognition by workers in the field that these powerful statistics can only be generated if each one of us makes an active effort.
Baseline information is recorded in a standardized format shortly after transplantation.
Centers with computer stored data can make electronic submissions from local, national, or international databases. All participants are informed of the study's emphasis on accuracy. All information reported by a center to the CTS is returned for verification. There are 4 mailing cycles a year in which clinical follow up information is requested. A center that fails to respond during 3 mailing cycles is inactivated from the study and can be reactivated only if the center's incomplete records are brought up to date.
