The report by Health Service Executive (HSE) inquiry team chaired by Prof Sabaratnam Arulkumaran, which was released yesterday, found that the most likely cause of her death was infection- with the risk of infection and sepsis increasing after her waters broke.
"A cascade of errors and uncertainty about the law on abortion contributed largely to her death," Irish Times said.
31-year-old Savita had died of septicaemia in her 17th week of pregnancy at University Hospital Galway in October last year and an inquest into her death held in April heard that she had been denied a potentially life-saving termination on the grounds that Ireland is a "Catholic country".
The HSE report says clinical staff at Galway Hospital failed to properly assess or monitor dying woman's condition.

It was found that the diagnosis of sepsis secondary to chorioamnionitis or septic shock should have merited expediting delivery to reduce risk of infection.
"The gravity of the situation was increasing but appears not to have been recognised and acted upon," it said.
"The interpretation of the (abortion) law related to lawful termination in Ireland, and particularly the lack of clear clinical guidelines and training, is considered to have been a material contributory factor in this regard," it added.
Prof Arulkumaran said that if Halappanavar had been his patient in the UK, he would have performed a termination earlier in order to counter the risk of sepsis.
He said the plan in her case had been to "await events", which he said was appropriate so long as it is not a risk to the mother or unborn baby.
He said the mother should not have to deteriorate to a point where she was gravely ill and "at death's door".
