BACKGROUND: The COVID-19 pandemic led to significant changes in maternity service delivery in England, including: antenatal appointments being cancelled or held by phone; women having to attend antenatal scans alone; partners not being allowed to accompany women during labor; visitor restrictions on postnatal wards; and limited postnatal support. METHODS: We conducted semi-structured interviews with 46 women aged 18-45 who had low-risk pregnancies and gave birth to their babies using NHS services in England between 1st March 2020 and 1st March 2021. RESULTS: Our thematic analysis of interview data generated key themes: profound negative impacts of birth partners not being allowed to accompany women (including on emotional wellbeing, birth preferences and care-seeking choices); deep frustration about policy variation between trusts and inconsistent implementation of guidance; women being more concerned about the risk of giving birth alone than of COVID-19 infection; and women turning towards private care or delaying seeking NHS care so that they could have the birth experience they desired. The latter two results are, to the best of our knowledge, unique to this paper. CONCLUSION: Our participants reported significant negative affects to their emotional and physical wellbeing because of maternity service restrictions. Going forward, efforts are required by policymakers and health service providers to re-establish trust in NHS maternity care and ensure capacity to provide for potential shifts in birthplace preferences. Health systems strengthening efforts should prioritise protecting the rights of women to access high quality, person-centred care in the event of future health emergencies that strain NHS capacity.
