May 2026: Thirlwall Inquiry report delayed to at least September 2026 · six-baby inquests relisted to 2027 · CCRC review active · Shoo Lee Panel: no medical evidence of deliberate harm.
The rise in mortality on the unit was presented as attributable, in substance, to deliberate acts by one individual.
The Countess of Chester neonatal unit in 2015–2016 was a Level 2 unit caring for infants whose acuity often warranted Level 3 tertiary care. The Thirlwall Inquiry has heard evidence of chronic understaffing, a sewage-back-up incident, pharmacy errors, and patterns of late transfers of extremely preterm babies who arguably should never have been on the unit. The Panel concluded that in every case it reviewed, deterioration was fully explicable by natural causes or sub-optimal clinical care — not deliberate harm. Independent epidemiological analysis shows the mortality rise is consistent with a unit caring for babies sicker than its design.
In every case we reviewed, deterioration was explicable by natural causes or identifiable clinical error — not deliberate harm.
The jury was largely shielded from the unit's broader context. Staffing gaps, plumbing failures, pharmacy mix-ups and late-transfer patterns were not foregrounded. The Crown's narrative placed all causal weight on the one nurse.
The Panel's case-by-case review attributes every deterioration to natural causes or identifiable clinical error. It recommends urgent re-examination on that ground alone.
