2.2. Data collection
2.2.1. Document collection
National (UK and NL) and international public maternity care documents (i.e., guidelines, protocols, and position papers) were prospectively collected from maternity care and service-user organisations between February 2020 and December 2020 (Table 1). Our initial plan was to collect documents until September 2020, however, due to the second wave of COVID-19, we felt it would be beneficial to continue data collection, which then ended in December 2020. We chose to focus on fifteen key organisations from September 2020 onwards, due to resource limitations. The fifteen organisations were identified to be those which had been the most influential on maternity service provision during the first wave of the pandemic. The list of key organisations was agreed with the ASPIRE Collaborative Group, comprising stakeholders from professional, service user, and policy backgrounds.
A framework of key safety and personalisation criteria was developed based on the expert opinion of the ASPIRE Collaborative Group (Supplementary File 1). Data were then extracted and mapped to the framework. From the 391 collected documents, 246 had data of interest for this analysis. In this manuscript the documents are indicated with the organisation name and document number (e.g., organisation_document number).
