Families to sue over hospital deaths in Bristol

Eight cases refer to Bristol Royal Hospital for Children

More families are coming forward to take legal action against a hospital trust in Bristol over its treatment of babies and young children.

The action against University Hospitals Bristol Trust (UHBT) covers the period between 2008 and 2012 and relates to deaths or treatment complications.

The claim is thought to centre on up to ten families - including seven whose children died following treatment.

The trust said paediatric cardiac surgery carried "significant risk".

A spokesman defended its mortality record, saying "despite the risks and the complex needs" of the children, the trust has results "among the best in England".

Solicitor Lawrence Vick, acting on behalf of the families, confirmed up to 10 families were intending to take action.

Eight cases refer to Bristol Royal Hospital for Children and two at nearby St Michael's Hospital.
