The success of a transplant programme can be measured by how long patients survive after transplant. This is often depicted as a graph of survival over time, or quoted as the percentage of patients surviving at particular time after the operation. The International Society of Heart and Lung Transplantation collects information from all heart/lung transplant centres in the world and produces survival figures which are freely available from its website Registry of the International Society of Heart and Lung Transplantation.
Overall, when compared with this data, the survival figures for Freeman patients are better. In particular, we have highlighted below three areas where our expertise yields excellent results:

| Survival to | 5 years | 10 years |
| International Society Data | 62% | 57% |
| Freeman patients | 86% | 78% |
Nearly four out of five children survive 10 years after a heart transplant at Freeman Hospital, compared with less than three children out of five, on average, in the rest of the world.

| Survival to | 5 years | 10 years |
| International Society Data | 53% | 33% |
| Freeman patients | 61% | 48% |
Almost half of patients who have a double lung transplant at Freeman Hospital survive 10 years, compared with a third of patients on average in the rest of the world.

| Survival to | 5 years | 10 years |
| International Society Data | 54% | 34% |
| Freeman patients | 62% | 52% |
Similarly, in patients who receive a lung transplant for cystic fibrosis, over half will survive for over 10 years at Freeman Hospital compared with a third of patients in the rest of the world.
