MATERIALS AND METHODS
This was a single centre retrospective study to determine the impact of COVID-19 pandemic and service modification on obstetric outcome in the Royal Bolton Hospital, Bolton, United Kingdom. The first confirmed case of Covid-19 infection in the United Kingdom was reported on the 31st January 2020 with lockdown measures subsequently announced on the 23rd March 2020, therefore data was collected around these important timelines. Data on Obstetric services and pregnancy outcomes of women during the pandemic (1st March to 31st May 2020) was compared to those of women in the time period prior to the pandemic and introduction of service modification (1st November 2019 to 31st January 2020).
All data was obtained from the Business Intelligence Unit of the hospital. Statistical analysis was performed using SPSS (version 22, SPSS Inc., Chicago, IL, USA). Data comparison between both groups was done using the nonparametric Chi-square test with the level of significance set at <0.05.
