Mental health services data quality

These data are from the Mental Health Services Data Set (MHSDS), which reuses operational data produced by NHS and independent providers. The MHSDS data are known to be incomplete and are therefore an undercount at England level.

This report presents information about the quality of data and statistics published each month. This includes provider-level data quality information to help users understand the impact of local data quality issues.

Data is available from April 2016.

This visualisation shows providers that submitted data to the MHSDS each month from April 2016. All providers that provide NHS-funded secondary mental health services should submit data to the MHSDS. NHS Digital is working with partners to identify non-submitting organisations and improve compliance.

All values are rounded to the nearest 5, except values that are 4 or lower (including 0) which are suppressed to prevent the identification of individuals.

Figures produced by aggregation in this report may differ from those published as this report calculates totals as the sum of rounded figures.

Suppressed values appear as blank cells in tables and are not counted in rounded totals.

Percentages are based on pre-suppressed values and rounded to zero decimal places, except where the numerator is 0-4, where the percentage is suppressed.
