Thirlwall report condemns dysfunctional management and delayed safeguarding at Countess of Chester
A public inquiry has concluded that the Countess of Chester Hospital NHS Foundation Trust completely failed to protect babies on its neonatal unit, allowing harm to continue for longer than necessary through a combination of dysfunctional management, weak governance and a fundamental misunderstanding of safeguarding.
The Thirlwall Inquiry report, published on 15 September 2026, examined events at the hospital between 2015 and 2016. Lady Justice Thirlwall described a system in which concerns raised by clinicians were not met with the action required under safeguarding procedures. She stated that suspicion of deliberate harm by a member of staff is sufficient to trigger protective steps; certainty of guilt is not required. The hospital’s own safeguarding policy at the time did not even contemplate the possibility of deliberate harm by staff, a gap the inquiry identified as critical.
The report identifies clear missed opportunities. Had safeguarding measures been taken by October 2015, after the death of one infant, and the nurse later convicted of the crimes removed from the ward, the subsequent deaths of two further babies and attacks on several others would have been prevented, according to the inquiry. Further chances to intervene were missed in early and mid-2016 as concerns continued without formal safeguarding processes being activated.
Senior managers delayed contacting the police for a prolonged period. Some executives referred to involving the police as “pressing the doomsday button” and appeared concerned about the hospital’s reputation. The inquiry criticises the then chief executive, Tony Chambers, for a dictatorial approach towards consultants and for contributing to the delay, stating that he succeeded in stalling or obstructing the investigation for almost a year. The director of nursing, Alison Kelly, who held safeguarding responsibilities, is found to have known action was required but failed to take it.
Communication with the families of the affected babies is described as dreadful. Parents were kept in the dark about emerging suspicions and internal reviews. In some cases medical records were shared with external reviewers without parental knowledge or consent.
A substantial section of the report looks beyond the individual trust and identifies wider failings across the NHS. These include shortcomings in regulation, employment practices, a culture that preferred to avoid individual accountability, and the repeated failure of the health service to learn lessons from earlier inquiries, including the case of Beverley Allitt. The Care Quality Commission’s inspection of the hospital in early 2016 is among the regulatory episodes scrutinised.
Lady Justice Thirlwall makes a series of recommendations intended to prevent similar failures. These include the installation of live-streaming monitors in all neonatal cots and incubators so that parents can observe their babies remotely, CCTV coverage of insulin storage refrigerators pending tighter access controls, clearer protocols for immediate safeguarding action and earlier police involvement, a strengthened individual duty of candour for senior managers, improved monitoring of neonatal mortality data, and mandatory safeguarding training.
Health Secretary Yvette Cooper has accepted the gravity of the findings, apologised to the families, and indicated that implementation of the recommendations will be tracked centrally.
The inquiry did not examine the safety of the criminal convictions or the medical evidence presented at trial. Those matters remain the subject of separate processes. The Thirlwall report stands as a detailed critique of institutional procedure, culture and response at the Countess of Chester and, more broadly, within the NHS.
In more detail: The Inquiry lays bare failures of safeguarding, leadership and accountability at the Countess of Chester Hospital
A FAILURE THAT WENT BEYOND ONE HOSPITAL WARD
The publication of the Thirlwall Inquiry has exposed a devastating failure of safeguarding and leadership at the Countess of Chester Hospital, where warnings concerning events on its neonatal unit were not acted upon with the urgency that the protection of extremely vulnerable babies demanded.
Lady Justice Thirlwall’s report, published on 15 September, concludes that there was a “complete failure” to protect babies on the neonatal unit. It describes dysfunctional management and governance, a gulf between hospital leadership and clinicians, and a fundamental failure to understand how safeguarding should operate when deliberate harm by a member of staff is suspected.
The report follows the convictions of former neonatal nurse Lucy Letby for the murder and attempted murder of babies in her care. But the purpose of the inquiry was different from that of the criminal courts. Lady Justice Thirlwall expressly states that her focus was not Letby’s guilt or the safety of her convictions, but what happened within the hospital, the experiences of parents, whether action should have been taken sooner, and whether NHS systems of management, governance and regulation were capable of protecting babies.
That distinction is important. The Thirlwall Inquiry is not another trial of Lucy Letby. It is an examination of what an institution entrusted with some of the most fragile lives in Britain did when warning signs began to appear.
WARNINGS THAT DID NOT PRODUCE ACTION
Perhaps the most troubling finding is also one of the simplest.
Safeguarding does not require certainty that a crime has occurred before protective action can be taken. When there is a credible suspicion that somebody working with vulnerable patients may be deliberately causing harm, the immediate responsibility is to protect those patients while the concerns are properly investigated.
Yet the inquiry found that this principle was not understood or acted upon at the Countess of Chester. Senior nurses did not accept that consultants’ concerns might be justified, while senior managers delayed contacting police. Internal and external reviews commissioned after concerns were raised failed adequately to address the possibility that deliberate harm was occurring.
The consequences identified by the inquiry are grave. Lady Justice Thirlwall concluded that some collapses and deaths could have been avoided had proper safeguarding practices been followed.
This is not simply a question of hindsight. It raises a fundamental issue about the culture of healthcare institutions: what should happen when respected professionals profoundly disagree about whether patients may be in danger?
The answer emerging from Thirlwall is that patient safety must come before institutional discomfort, professional hierarchy or fear of reputational damage.
PARENTS LEFT OUTSIDE THE DOOR
There is another story within the report that risks becoming lost among discussions of hospital management, police investigations and legal proceedings: the experience of the families themselves.
Parents entrusted their premature and seriously ill babies to a neonatal service at a moment when they were extraordinarily vulnerable. According to the inquiry, some were subsequently kept unaware for years that concerns existed that their children might have been deliberately harmed.
Parents were not properly informed about reviews. Consent was not obtained before some babies’ medical records were shared with outside experts and organisations. The inquiry records the anger of families who believed protecting the hospital’s reputation had taken precedence over keeping them informed. Lady Justice Thirlwall described the lack of consideration shown towards parents as reprehensible.
The Health Secretary, Yvette Cooper, apologised to the families following publication of the report, telling Parliament that 13 families lay at the heart of the inquiry and acknowledging the years they had waited for answers.
No reform of governance can undo what those families have experienced. But their treatment provides one of the clearest tests of whether the NHS learns from this report: when something goes seriously wrong, families should not have to fight their way through an institution to discover what that institution already knows.
WHEN SPEAKING UP BECOMES THE PROBLEM
Thirlwall also describes an organisation in which the people raising concerns could themselves become the focus of management action.
Consultants who had expressed concerns were drawn into Letby’s grievance process, and three were instructed to apologise to her. Plans were developed, although ultimately abandoned, for Letby to return to the neonatal unit.
There is an uncomfortable lesson here extending well beyond Chester.
Every large organisation needs procedures protecting employees from unfounded accusations. Healthcare workers are entitled to fairness just as anyone else is. But protecting an employee from premature judgment and protecting patients from potential harm are not mutually exclusive responsibilities.
A functioning safeguarding system must be capable of doing both.
THE NHS MUST LEARN, NOT MERELY APOLOGISE
The Government has already announced measures in response to Thirlwall, including urgent work on cameras in neonatal settings, strengthened guidance surrounding the storage and use of insulin, tougher accountability arrangements for senior NHS managers, improvements concerning neonatal deaths and a central system for tracking whether recommendations from major maternity and neonatal inquiries are actually implemented.
That final proposal may prove particularly significant.
The British health service has accumulated a long history of inquiries, reviews and recommendations following serious failures of care. Each produces promises that lessons will be learned. The more difficult question is whether those lessons remain embedded after public attention moves elsewhere and senior personnel change.
A recommendation written in a report protects nobody unless somebody is responsible for implementing it, monitoring it and asking why it has not happened.
THE LEGAL CASE REMAINS SEPARATE
The controversy surrounding Lucy Letby’s convictions has not disappeared with publication of Thirlwall.
Her convictions are currently the subject of an application to the Criminal Cases Review Commission, which has confirmed that its review is underway. The CCRC does not decide whether somebody is innocent or guilty. Its function is to investigate potential miscarriages of justice and determine whether new evidence or argument creates a real possibility that a conviction would not be upheld if referred back to the appellate courts.
Those proceedings must be allowed to follow their proper course.
The existence of serious failures within the Countess of Chester Hospital does not itself establish that Letby’s convictions are unsafe. Equally, reporting the legal questions now being examined does not diminish the importance of investigating how the hospital responded when doctors raised concerns.
They are separate questions requiring separate evidence.
Meanwhile, Cheshire Constabulary continues Operation Duet, its investigation concerning the response of senior leadership at the hospital. Police said following publication of Thirlwall that their corporate manslaughter and gross negligence manslaughter investigations remain ongoing. No conclusion about criminal liability should be drawn while those investigations continue.
A TEST FOR THE NHS
The enduring importance of Thirlwall may ultimately lie beyond the extraordinary circumstances that brought the inquiry into existence.
Hospitals are complicated institutions. Doctors disagree. Diagnoses change. Statistics can produce patterns that later prove misleading. Staff must be protected from unjust accusations, while patients must be protected from possible harm. None of these responsibilities is simple.
But safeguarding exists precisely because certainty often comes too late.
The central lesson from Thirlwall is therefore not that every suspicion should become an accusation. It is that credible concerns about patient safety must trigger protection, investigation and scrutiny rather than paralysis.
The NHS remains one of Britain’s most valued public institutions, staffed overwhelmingly by people whose working lives are devoted to caring for others. Acknowledging that does not require overlooking institutional failure. On the contrary, public confidence in the health service depends upon its willingness to expose failure, protect those who raise legitimate concerns and tell families the truth when something has gone badly wrong.
For the families whose babies were at the centre of events at the Countess of Chester, reforms and recommendations arrive painfully late.
For every family who will entrust a premature baby to an NHS neonatal unit tomorrow, they cannot arrive too soon.
