An interim report into the pseudomonas outbreak that occurred at two hospitals in Northern Ireland has recommended that one of the affected neonatal units should be replaced.

Stormont Health Minister Edwin Poots had ordered an investigation into the deaths of four babies following outbreaks of pseudomonas at hospitals in Derry and Belfast.

One baby died at Altnagelvin hospital last December after contracting the infection; three other children passed away after being infected at Belfast's Royal Jubilee Maternity hospital in January.

A review panel from the Regulation and Quality Improvement Authority published an interim report today, recommending the closure of the neonatal unit at Belfast's Royal Jubilee Maternity hospital.

The report concluded there was a lack of appropriate accommodation for isolation or cleaning equipment in the unit and said that only sterile water should be used when washing babies there.

It also recommended the replacement of all taps at every neonatal unit in Northern Ireland.

The outbreak was linked to water from contaminated taps.

Mr Poots says he intends to implement all 15 recommendations as soon as possible.

A full report into the pseudomonas outbreak is due to be published by the end of next month.
