Cystic Fibrosis Ireland has expressed upset and frustration over a two-and-a-half-year delay in progress on building a promised new inpatient Cystic Fibrosis unit at Beaumont Hospital in Dublin.

It said that in May 2016, the Programme for Government committed to "immediately proceed to the design and planning stage" for a dedicated unit at the hospital for inclusion in the 2017 Capital Plan.

CFI will brief members of the Oireachtas on the issue later today.

Currently there are 160 people with Cystic Fibrosis who attend Beaumont, which has seven inpatient rooms for those with the condition.

CFI said that this means a ratio of around 23 patients for every bed, with long delays for those seeking access to inpatient care and likely to get worse as winter approaches.

It is expected that the new facility will cost €11m.

CFI wants the unit to provide for 20 beds in total at Beaumont.

CFI and North Dublin charity, CF Hopesource, have committed to raising €1 million towards the project.

Beaumont is one of five nationally designated adult specialist centres for CF.

Cystic Fibrosis Ireland’s Chief Executive Philip Watt said the facility was in the 2016 Programme for Government and patients now wanted a clear written schedule on when the 20-bed unit will be built.

In a statement, Beaumont Hospital said plans to develop a new Cystic Fibrosis unit are at an advanced staged with the design of a two-storey unit containing 20 single, en suite rooms complete.

It said the process to secure planning permission for the development is due to begin later this month.
