Thirlwall Inquiry finds consultant pediatrician prioritized Lucy Letby over vulnerable baby patients.

The Care Quality Commission acknowledged that its inspection of the Countess of Chester Hospital was not sufficiently investigative or inquisitive, and issued an apology over its regulatory failures.
The inquiry found that the hospital’s safeguarding policy did not address the possibility of deliberate or malicious harm, leaving staff without a clear process for responding to suspicions about intentional attacks.
Among the inquiry’s recommendations was the use of CCTV in neonatal units, including cameras covering every cot and incubator, to help protect babies and investigate suspected harm.
The report described Letby as repeatedly untruthful, resistant to management and at times inappropriate and callous with patients; it also documented a shouting match between her and a senior manager.
The £18 million Thirlwall Inquiry recommended that the NHS adopt a standard protocol for suspected deliberate harm so managers cannot decline to investigate when concerns are raised.
