UK Early Pregnancy Surveillance Service (UKEPSS)

UKEPSS logoThe UK Early Pregnancy Surveillance Service (UKEPSS) is a network designed to study uncommon, but serious conditions in early pregnancy.

UKEPSS is a joint initiative of the Association of Early Pregnancy Units (UK), the Early Pregnancy Clinical Studies Group, the Miscarriage Association, and the Ectopic Pregnancy Trust, and has been endorsed by the Royal College of Obstetricians and Gynaecologists.

Uncommon conditions in early pregnancy contribute to the morbidity and mortality of mothers in the UK. Maternal mortality reports recommend improvements in the care of mothers with problems in early pregnancy such as infection, miscarriage and unusual presentations of ectopic pregnancy.

By collecting data from all over the country, we can look for better ways to care for these women and improve their health outcomes and experiences.

This website will tell you more about the conditions we are studying and how you can get involved.


We are delighted to announce the launch of the first UKEPSS study.

The condition for surveillance is caesarean scar pregnancy.

Please start reporting your cases from this month.

If you are not already on the UKEPSS network, please register by emailing, and also let your colleagues know about us.

Thank you for your support.
