Unlike stillbirths and neonatal deaths, the number of miscarriages which occur each year in the UK are not measured or reported. While there are no UK-wide data on miscarriage, some miscarriage-related data are collected across the four nations. However, data are often limited to the hospital setting and inconsistent records, definitions and digital systems makes collation challenging, even before integrating other areas of the health system, such as primary care.

Work is underway in each of the devolved nations to consider how to collect data on miscarriage going forward. This briefing note outlines what data are currently available in each nation, what improvement work is underway and what further action is required.
