Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many and what proportion of sepsis cases have been identified in (a) children and (b) adults with Acute Lymphoblastic Leukaemia in the last 12 months.

The Department does not hold data on the number of sepsis cases or the proportion of those cases that have been identified in children or adults with Acute Lymphoblastic Leukaemia. However, the National Disease Registration Service in NHS England, as the national cancer registry, collects diagnosis and treatment data on cancer patients in England, and is available at the following link:

In 2021, the most recent complete year of data available, 614 patients with Acute Lymphoblastic Leukaemia were recorded as being admitted to hospital for treatment within the first year of being diagnosed. Of those patients, 49% of children and 51% of adults had at least one recorded diagnosis of sepsis.
