More cystic fibrosis patients would live for longer if the NHS accepted more donor lungs and directed them to "those most in need", according to a specialist doctor.
Professor Andrew Fisher from the Institute of Transplantation, Freeman Hospital and Newcastle University, explained:
Changes should be made to the way lung transplants are allocated on the NHS, so more cystic fibrosis sufferers are prioritised, a charity has said.
The Cystic Fibrosis Trust called on NHS Blood and Transplant to develop a new "lung allocation system" that balances the needs to medical urgency and long-term outcomes.
The mortality rate of cystic fibrosis sufferers who die waiting for a lung transplant is a "scandal", a health charity has warned.
The Cystic Fibrosis Trust criticised the "transplant lottery" as it emerged one in three with the lung disease die while waiting for a transplant.
Sufferers on the transplant list wait on average, for more than a year - 412 days, the charity said.
More than 10,000 people from across the UK suffer from the life-shortening condition which is caused by a faulty gene.
It leads to a sticky mucus clogging the lungs and digestive systems which makes it hard for sufferers to breathe and eat.
