This publication contains three separate CSV files for the reporting months: one set for the final (December 2025) data and one set for the provisional (January 2026) data.
The contents of the three files are as follows:
• CSV Data: Aggregate figures based on the MSDS, for a standard set of metrics including the total numbers of booking appointments, deliveries, and babies born within the reporting month. Breakdowns are provided at several organisational and regional levels including National, Local Maternity and Neonatal System (LMNS), and Provider (trust).
• Data Quality: Counts broken down by provider, showing the VODIM (Valid, Default, Invalid, or Missing) status of the records submitted for each data field within the MSDS. This file contains information about data quality only and should not be used to assess activity and outcomes. It reports on all the data provided at submission and will include information about records that are not included in the final analysis contained within the other two CSV files.
• Measures: Aggregate figures based on the MSDS, for several specific sets of metrics including but not limited to those for Clinical Quality Improvement Metrics (CQIM), Continuity of Carer (CofC), mother’s body mass index (BMI), and the Saving Babies Lives Care Bundle v3 (SBLCBv3). Breakdowns are provided at several organisational and regional levels including National, Local Maternity and Neonatal System (LMNS), and Provider (trust). This file only contains CQIMBreastfeeding6to8Weeks figures for final data, not provisional data, as this metric requires Community Services Dataset (CSDS) records which are not available within the required timeframe.
This publication is accompanied by a Metadata file located on the MSDS guidance hub which contains more granular detail about the contents of the above files, including information about the definitions and logic used in their construction.
In accordance with the suppression methodology guidance for this dataset, rounding has been applied to all figures as follows: counts of zero are shown as zero, counts of 1-7 are rounded to 5, and all other counts are rounded to the nearest 5, with rates (where relevant) calculated from the rounded numerator and denominator numbers. There are four exceptions to this, for rare events, where rates are calculated from unrounded numbers but are not shown where the numerator is less than 8. This applies to CQIMTears, CQIMPPH, CQIMPreterm, and CQIMApgar.
