An inquiry into the Countess of Chester Hospital has concluded that some of Lucy Letby’s murders could have been prevented if staff had acted sooner, a finding that places the hospital’s response at the centre of one of Britain’s most shocking criminal cases.
The report matters now because Kathryn Thirlwall delivered her final findings on Tuesday, and those findings land while Letby remains in custody serving life without parole for murdering seven babies and attempting to murder six others. She also has a later conviction for another attempted murder charge, and she maintains her innocence.
Thirlwall said the hospital was marked by dysfunctional management and a basic lack of understanding of safeguarding. Her criticism was not about whether Letby was guilty; she made clear that her focus was the inquiry’s terms of reference, not the convictions themselves. But the implication of her report is stark: once staff suspected Letby might be harming babies deliberately, that suspicion alone should have triggered safeguarding action.
That did not happen. Thirlwall said no one seems to have treated suspicion as enough to protect patients, even though the inquiry found a complete failure to protect babies at the hospital. Prosecutors had said Letby attacked newborns between June 2015 and June 2016 by giving them an overdose of insulin, injecting them with air, or force-feeding them milk, and the report says at least some of those crimes could have been prevented if action had been taken sooner.
There is still a gap in the public record on which deaths might have been avoided and what earlier intervention would have changed them, but the message of the report is plain: the breakdown was not only about one nurse’s crimes, but about a system that did not move when warning signs appeared. Thirlwall has also urged the government to tackle long-standing underfunding of hospital services for babies and children and suggested cameras for cots and incubators, tighter insulin storage safeguards, and an NHS protocol for suspected deliberate harm.
The next stage now shifts beyond the inquiry itself. The Criminal Cases Review Commission is considering an application from Letby’s legal team, and the report will be part of the material weighed as the legal challenge moves forward. Three senior hospital managers remain under investigation after arrests last year, including one also suspected of perverting the course of justice, leaving the hospital response under scrutiny long after the inquiry has closed.
