COVID-19 Update

ISN continues to monitor the COVID-19 outbreak and remains committed to its mission of building capacity around the world. Providing support to LMICs remains a key priority. We will continue to adapt our response to this unprecedented situation as it evolves.

The ISN-TTS Sister Transplant Centers (STC) Program is a joint partnership set up between ISN and The Transplantation Society (TTS) to create new kidney transplant centers and develop existing kidney transplant programs in emerging economies. 

You can apply to enter the program for the first time or request an upgrade to the next level.

Any two transplant centers can form a partnership if at least one center is from a low-resource country (low, lower-middle or upper-middle income country as per World Bank List of Economies) and the centers are chaired/run by an ISN or a TTS member. They need to submit a detailed action and budget plan, and a clear description of how the collaboration will develop the services of the emerging center and positively reflect the supporting center.

New sister pairs apply to enter the program at level C and typically stay two consecutive years at the same level. At each level, centers must submit progress reports stating their accomplishments in order to progress within the different stages of the program. They will be assessed at each change of level to establish whether they are eligible to acquire more support and benefits. Graduated centers can apply for the Trio Program, encouraging them to support a third emerging center within their region. Honorary C/B Levels are assigned to centers which have failed to upgrade from level C/B to B/A. Honorary sister pairs have one extra chance to apply for an upgrade.
