The Thirlwall report can expose NHS failure. It cannot tell families which babies would have lived.

Lady Justice Thirlwall’s report is the official account of how concerns about Lucy Letby were handled at the Countess of Chester Hospital. Its hardest task is separating institutional failure from claims about individual deaths that the evidence cannot prove.

The Thirlwall Inquiry’s report is published today after examining how Lucy Letby was able to kill and injure babies at the Countess of Chester Hospital, and why warnings did not trigger effective action. Its value will lie less in retelling the crimes than in showing what the NHS knew, what it did with that knowledge and what it failed to ask.

The inquiry was never a second criminal trial. Its terms covered the conduct of the hospital’s board, managers, doctors and nurses; the handling of concerns; whistleblowing; communication with families; neonatal monitoring; and whether earlier action could have prevented further harm. Lady Justice Thirlwall cannot determine criminal or civil liability, and the inquiry’s remit does not overturn Lucy Letby’s convictions. ¹ ²
The central institutional question is not whether managers looked worried. It is whether they acted. Evidence published during the hearings described concerns about unexplained collapses and deaths, arguments over mortality data, internal reviews and repeated attempts by consultants to escalate their fears. The terms of reference specifically ask whether concerns should have been raised earlier, whether existing speaking-up systems worked and whether the hospital’s culture weakened them. ² ³
Family communication is part of the failure, not a side issue. The inquiry was instructed to examine what parents were told about their babies’ condition, treatment, prognosis and likely cause of death. That matters because families were expected to trust a system that may not have been honest with itself about what was happening on the unit. ²
The report must be precise about preventability. A finding that leadership, escalation or safeguarding failed does not automatically prove that a particular death could have been avoided. The strongest conclusion would identify where earlier intervention could reasonably have changed the outcome, and where the evidence stops short. Anything broader would turn institutional blame into a claim the inquiry cannot safely make.

The NHS has already had decades of inquiries, recommendations and promises about learning lessons. The Thirlwall material itself records the failure to implement or follow through on earlier healthcare recommendations. ⁴ The public interest today is therefore practical: whether this report produces named duties, measurable oversight and consequences, rather than another solemn document placed in the national cupboard.

No government implementation response was identified in the inquiry’s publication material before release. The Countess of Chester’s board papers anticipated a regional, multi-stakeholder quality review after publication, but that is preparation, not proof of reform. ⁵ The families should not have to wait another inquiry to discover whether this one changed anything.

The Thirlwall report can expose NHS failure. It cannot tell families which babies would have lived.
