There does not appear to be an agreed list of clinical and organisational variables that capture safe and personalised outcomes in maternal and neonatal care, and the processes that underpin them. Even if these variables were defined, it is not clear that Trusts collect these variables routinely. Even if they are collected routinely, accessing routinely collected accurate NHS data is known to be problematic. The ASPIRE COVID-19 team therefore undertook an iterative process to develop a variables list for safe and personalised care that was likely to capture processes of care that may underpin safety and personalisation, and outcomes that measure these phenomenon; that were likely to be (or should be, based on policy requirements) collected at Trust level; and that could potentially be supplied with a minimum of extra resource by Trust teams, and without high data access costs to the ASPIRE COVID-19 project. The resulting Safe and Personal Domain Variable List was developed iteratively, based on the following steps: • Initial development of a list of variables usually reported in the literature, and based on the principles of Better Births Better Births report through the NHS Maternity Transformation Programme.• A subsequent iterative round of discussions amongst ASPIRE COVID-19 Co-Investigators, researchers, and Advisory/Steering Group members with direct and indirect experience, requesting views on how the original variable list maps to the working framework for data collection and what extra variables might be required, ideally, to populate the framework. • Addition of variables emerging from insights from the earlier documentary analyses and in-depth interviews in the ASPIRE COVID-19 Trusts.• Submission of a ‘long list’ of both the organisational and clinical variables to Trusts to assess which ones could be provided easily, with difficulty, or not at all.• Exclusion of variables that none of the ASPIRE COVID-19 Trusts reported as being recorded/obtainable with reasonable effort locally.Following these steps, the final variables lists were confirmed and Trusts provided data on key quantitative indicators from routinely collected data (see file: Clinical_data_metadata_variables_all_trusts; and file Organisational_data_metadata_variables_all_trusts).Other quantitative data was taken from the Family and Friends test, Safe Staffing data and UK Government data on COVID-19 incidence and hospital admissions.
