Elsewhere around the country, other trusts have also been forced to face their failures, often by grieving families.
In March 2022, an investigation into services at the Shrewsbury and Telford NHS trust found that more than 200 mothers and babies could have survived with better care. Then, in October that year, a review into maternity services at East Kent Hospitals University NHS trust found that at least 45 babies might have survived if they had been given proper treatment.
And an ongoing review into the maternity care provided by Nottingham University Hospitals NHS trust, due to be completed next year, is set to be the biggest yet, with around 2,500 cases being examined.
Even that does not tell the full story. Families in several areas, including Sussex, Leeds and Oxford, want local investigations into their maternity services. And an annual review of units by inspectors the Care Quality Commission (CQC) paints a woeful picture.
In the commission's latest report, published in September, not a single one of the 131 units inspected received the top rating, Outstanding, for providing safe care.
About a third (35%) were rated as Good for safety, around half (47%) were rated as Requires Improvement while almost a fifth (18%) were deemed Inadequate, the lowest grading.
"While we identified pockets of excellent practice," wrote the CQC, "we are concerned that too many women and babies are not receiving the high-quality maternity care they deserve."
Professor James Walker, who used to be the clinical director for HSIB, said that from his visits around England, the problem was that maternity units "didn't have the skills, the finances, or the drive to actually make the changes that are required."
Ida Lock's inquest was a case in point. What emerged over the inquiry was that the midwife delivering Ida was not compliant with crucial training in heart-rate monitoring, that staff did not know how to investigate incidents or realise they should inform external regulators of an unexpected death.
"It's deeply distressing," says Dr Kirkup. "It's bad enough that other trusts didn't listen, but for it to happen again in this same trust is unforgivable."
