But the inquiry revealed NHS England had been aware since 2013 that there were concerns about maternity services. Despite this, "the safety structures within NHSE did not see the trust as being a problem," said the review.
Various efforts were made by NHSE to help the trust but they "failed to secure the necessary improvements in the services provided," and so babies continued to die unnecessarily.
NHS England's answer to the persistence of the problem, found the inquiry, was "a pattern of hiring and firing, initiated by NHSE. It is clear that this approach was not just ineffective in East Kent, but wholly counterproductive. These decisions appear to us to have been made separately from any question of accountability."
Helen Gittos, who lost her daughter Harriet in 2014 at East Kent, is glad that NHSE is being scrapped.
"When families met with Wes Streeting to talk about maternity safety in the autumn, one of our messages was that NHSE was part of the problem, not part of the solution.
"It has been incredibly frustrating to see NHSE's response to successive reviews of maternity services. It's almost as if they haven't read the reports", she said.
The Maternity Safety Improvement Programme, led by NHSE, has not brought the kind of improvements "women and families so desperately need", she added.
An NHS England spokesperson said: "Our staff work exceptionally hard to keep patients safe and we have made significant progress in this area through the implementation of the first ever NHS Patient Safety Strategy, which introduced an NHS-wide programme of training and education in patient safety.
"This strategy, which evolves over time to ensure it meets current challenges, has transformed the governance of safety across the NHS."
NHS England has published hundreds of independent investigations, at a cost of millions of pounds, into the care and treatment that patients have received.
Many of these have been welcomed by the families, providing necessary answers. Individual staff have been commended for their engagement with families, too.
But on too many occasions, it has proved an almighty struggle for them to act.
At the heart of many of the patient safety scandals uncovered in recent years has been a poor culture, an unwillingness to openly engage with patients. At the root of those problems has been poor behaviour in particular trusts, but repeatedly, families have complained that NHSE's own secrecy has added to the problem.
While individual NHS trusts regularly publish their board papers well ahead of meetings, for years NHSE itself didn't publish any board papers until the meeting was over – proof, said critics, of its lack of openness to scrutiny. Its papers are now published – about two hours before a meeting.
