Aidan Flahavan at Cian O’Carroll Solicitors led this case, the settlement of which was approved by the High Court this week.
It is a complex medical negligence case arising from the death of Dymphna D***s, a much-loved wife, mother and grandmother who died from acute liver failure and multi-organ failure caused by a toxic reaction to prescribed medication.
The proceedings, brought by her husband Frederick D***s and daughters Aiveen D***s and Kerena Turner, settled following mediation immediately before the commencement of the trial.
The Defendants, who were GP Siobhán Kierans, at Tallaght Medical Centre, Redwood View, Tallaght, and Tallaght University Hospital both admitted breach of duty and causation. Both furnished written apologies that were read out in Court and they also agreed to pay substantial damages together with the Plaintiff's legal costs in full.
The central issue in the case was that regular liver function monitoring, which was intended to occur throughout treatment, never happened.
The High Court heard that had those tests been carried out, the deterioration in Mrs D***s' liver function would have been identified early and the medication discontinued.
Mrs D***s did not die because she suffered a rare complication of treatment. She died because the monitoring intended to detect that complication never took place.
In their apology, Tallaght University Hospital stated:
"It is a matter of deep regret that there were shortcomings in the care we provided to Dymphna which resulted in her death, and I wish to sincerely apologise for this."
