Statistics on Women's Smoking Status at Time of Delivery: England

The 2024-25 quarterly publications have included information from two data sources: the Smoking at Time of Delivery (SATOD v1) data collection, and the Maternity Services Dataset (MSDS, SATOD v2) for comparison, with a view to retiring SATOD v1 at the end of 2024-25. Following a Health and Social Care Statistics consultation carried out in 2024, a decision has been made to cease the SATOD v1 data collection and replace with SATOD v2 for future reporting as the national estimates from both data sources are closely aligned. This has been driven by the need to reduce burden on data collection and duplication across the NHS. MSDS data is submitted monthly by Trusts so sub-ICBs (or other commissioning entities) are no longer required to submit data for this collection from Q1 2025-26. A final publication for Q4 2024-25, incorporating data from both sources, was published in June 2025. Subsequent publications will include data from MSDS only.
