Methods
The Datix patient safety incident reporting system was used to identify all cases of placental abruption and in-utero death (IUD) at Imperial College Healthcare Trust (Queen Charlotte’s and Chelsea Hospital and St Mary’s Hospital). All cases of IUD and placental abruption that occurred between 1st January - 30th June 2020 (pandemic period) and 1st January - 30th June 2019 (pre-pandemic period) were included. There were no exclusion criteria. Anonymised data was collected retrospectively from the electronic health records. Demographic and clinical data was recorded to be used for comparison with cases from 2019.
