Why she matters in this case
Dr Blencowe’s professional frame is different from most of the Panel’s signatories. She is not a clinical neonatologist but a perinatal epidemiologist — which is to say, the specialist who studies neonatal mortality and morbidity at a population level. Her contribution to the Panel is specifically about whether the Countess of Chester cluster is, statistically and epidemiologically, the kind of cluster that requires a criminal explanation.
Her answer, as a Panel signatory, is that it is not. Clusters of deaths on struggling Level 2 NICUs with the kinds of infrastructure, staffing and outbreak pressures documented at the Countess of Chester are a recognisable epidemiological signal of systems failure, not of criminal pattern.

What her contribution adds
Much of the public debate about the Letby case turns on the question: is a cluster of deaths on one unit, one nurse overlapping with each, statistically anomalous or statistically expected? This is an epidemiological question, not a clinical one. Dr Blencowe’s professional specialisation is the answering of that question. Her signature on the Panel report is the global perinatal epidemiology community saying that the Countess of Chester cluster does not require a criminal explanation to be epidemiologically accounted for.
