Cystic Fibrosis campaigner Orla Tinsley has said an agreement to provide a specific number of dedicated beds for Cystic Fibrosis patients at St Vincent’s Hospital in Dublin urgently needs to be renegotiated.

Ms Tinsley was speaking after a Cystic Fibrosis patient told RTÉ's This Week programme that she was afraid to go to the hospital even though she knows she has a chest infection and needs treatment.

Shauna Morrissey from Co Tipperary, who had a liver transplant in August, said that her chest infection is getting worse.

However, she did not attend the hospital as she would normally do after hearing that there were not enough beds for Cystic Fibrosis patients to be isolated.

Several Cystic Fibrosis patients left the hospital after they were told there would be no isolated beds available in the Cystic Fibrosis unit. Some are on mixed wards.

But Ms Morrissey said that she would not go into a mixed ward where she would be exposed to infections.

The 21-year-old said that she is more exposed to infections as a result of her recent liver transplant.

She told the programme that as a Cystic Fibrosis sufferer she was "insulted" by the way the hospital had handled the issue and said "cattle in the field" would be treated better.

Ms Tinsley told This Week that it was grinding that after years of campaigning there was still an issue with ill Cystic Fibrosis patients getting the treatment they need in proper conditions.

Ms Tinsley is an inpatient at St Vincent’s and left the hospital for a short period to speak to the programme.

The Cystic Fibrosis Association of Ireland said the hospital is due to meet on the issue this week.
