What does the COPS study involve?
We have linked healthcare records on all pregnancies in Scotland including early pregnancy losses (e.g. miscarriage, ectopic pregnancy), terminations of pregnancy, live and stillbirths and neonatal health records, with COVID-19 test results and COVID-19 vaccine records.
We have information on all women who were pregnant on 1st January 2015, and pregnancies from 1st January 2015 onwards. Records were updated monthly until August 2022.
We are using these healthcare records to describe how many pregnant women had COVID-19 and how many were vaccinated. We are also studying if COVID-19 increases the risk of miscarriage, stillbirth, congenital anomalies, low birthweight, preterm birth, need for specialist baby care (admission to a neonatal unit) or baby death; and providing evidence on the safety and effectiveness of COVID-19 vaccination for women and their babies.
The healthcare record linkage and analysis will take place within Public Health Scotland. The study dataset will be ‘pseudonymised’ before analysis. Pseudonymised or 'de-personalised' data is information that does not contain items that directly identify individuals, such as name and address or unique patient number. However, pseudonymised information is still about individuals and so needs to be handled with care. It might, in theory, be possible to recognise or re-identify individuals from pseudonymised data, for example if individuals have very rare pregnancy complications, or if the pseudonymised data was combined with different sources of information, for example from news reports. For this reason, Public Health Scotland will treat the COPS study data very carefully, using well established and strict controls to keep the data safe.

How will COPS benefit the public?
Understanding the effects of COVID-19 and COVID-19 vaccination at different stages during the maternity journey from conception through to birth will help inform policy and advice to pregnant women and those considering pregnancy.
How will results from COPS be used?
The results of the COPS study are used by Public Health Scotland and the Scottish Government. Official statistics on COVID-19 infection and vaccination in pregnancy from COPS are released through Public Health Scotland’s COVID-19 weekly report for Scotland.
