The Thirlwall Inquiry has released its findings regarding the actions of Lucy Letby at the Countess of Chester Hospital, describing a complete failure to protect infants from harm. The inquiry, led by Lady Justice Thirlwall, concluded that hospital management and governance systems were dysfunctional and missed multiple opportunities to stop Letby. The report states that if specific safeguarding actions had been taken by October 2015, the deaths of two infants and the attacks on five others could have been prevented.
The inquiry was established in September 2024 following Letby’s conviction for the murder of seven infants and the attempted murder of seven others. Over a six-month period, the inquiry heard testimony from more than 130 witnesses and reviewed 400 statements. The resulting report spans three volumes and exceeds 1,100 pages, examining why concerns raised by consultants were not addressed by hospital executives for a significant period.
Lady Justice Thirlwall found that hospital executives, including former medical director Ian Harvey and former chief executive Tony Chambers, sought to control the narrative and delayed contacting the police for nearly a year. The report noted that a serious incident panel meeting in August 2015 treated an unexpected death as a formality rather than connecting it to previous fatalities. Additionally, the inquiry found that the Care Quality Commission (CQC) inspected the facility in February 2016 but failed to look beyond the information provided by hospital leadership, while Letby continued to attack infants until June of that year.
For families of patients, the report details what Thirlwall described as "reprehensible" treatment, noting that parents were kept in the dark for years about suspicions of deliberate harm. The findings indicate that hospital managers used the fear of upsetting parents as a justification to avoid police involvement. The report also highlights a "toxic negativity" within the NHS that persists today, which discourages staff from speaking out. This suggests that without structural changes, healthcare workers may continue to face professional retaliation or be "managed out" when raising safety concerns, as occurred with the consultants at the Countess of Chester.
The inquiry has issued 17 recommendations to prevent future incidents, including the installation of baby monitors on all neonatal cots and incubators. It also calls for restricted access to insulin through biometric data or CCTV monitoring, as Letby used the substance to harm two infants. Thirlwall further recommended the creation of an NHS-wide "suspicion of deliberate harm" policy that would be contractually binding for all staff. The government and NHS leadership must now determine which recommendations to implement and establish a timeline for these safety upgrades across the health service.
