The Maternity Services Monthly Statistics reports for April 2019 onwards are the first to come from the new version of the Maternity Services Data Set (MSDSv2).
This version of the data set has had numerous changes; to field names, table names, the clinical coding we receive and the structure of the data set itself. Our collection portal has also been redeveloped, to enable consistency in submissions and efficiency in analysis and data linkage in the fullness of time. System suppliers are at different stages on developing their new solution and delivering that to trusts. In some cases this has limited the aspects of data that could be submitted to NHS Digital.
These changes have meant that we have not received as much data from every trust as we did in early 2019 under the previous version of the data set. We expect their completeness to improve over time, as they did with the previous version of the MSDS, and are looking at ways of supporting the improvements.
