i. By 31 March 2027, all hospital Trusts must have in place effective mechanisms for Board-
level monitoring of all deaths of children and babies.

The Inquiry asked National Health Service (NHS) hospital trusts to monitor child deaths. In an oral statement in September 2026, the Secretary of State for Health and Social Care said the government "will, of course, consider the entire report and set out a full response" (Department of Health and Social Care response, Sep 2026). The Minister quoted the Inquiry's finding that the Countess of Chester Hospital board received no reports on infant deaths, but board-level monitoring and escalation routes across trusts are not mentioned in the statement (Department of Health and Social Care response, Sep 2026). The record holds nothing dated later than the response of September 2026 (Department of Health and Social Care response, Sep 2026).

Serious consideration should be given by DHSC to the setting up of a panel of independent
experts from all specialties to be called upon in situations where there are emerging
concerns about an individual and harm to a patient or patients. A team from any specialty
or combination of specialties would be drawn from the panel to conduct a swift, technical
investigation into the concerns raised. This may most often be necessary where there are
concerns that harm is being or has been caused inadvertently.
The precise make-up of the panel should be determined by DHSC but could include,
for example:
a. two doctors and two nurses from each clinical specialty
b. four senior managers
c. four pathologists including paediatric and perinatal pathologists
d. other experts as decided by DHSC.
Where necessary, a small team (always including clinicians from the relevant specialty/
specialties) would be drawn from the panel to carry out an independent investigation into
clinical concerns. Such investigations should always include safeguarding considerations
(including contacting the police). In addition to reporting their findings to the Trust and
DHSC, the experts would be available to be called as witnesses in any proceedings that
may follow.2

The Inquiry asked health ministers to consider creating an expert panel on clinical harm. In an oral statement in September 2026, the Secretary of State for Health and Social Care said that the government "will, of course, consider the entire report and set out a full response" (Department of Health and Social Care response, Sep 2026). Made on the day the inquiry report was published, the statement named neither this recommendation nor the proposed panel of independent experts (Department of Health and Social Care response, Sep 2026). The record holds nothing dated later than the response of September 2026 (Department of Health and Social Care response, Sep 2026).

DHSC and NHS England must ensure that, by June 2033, there are 37 doctors in training
posts as paediatric and perinatal pathologists, in line with the workforce requirement set
out by the Royal College of Pathologists in the November 2025 Paediatric and Perinatal
Pathology Workforce Report. The incentive scheme should remain in place and funded
until at least 37 doctors are in training posts as paediatric and perinatal pathologists.

to include:
