Data quality

The DQMI is a monthly publication about data quality in the NHS, which provides data submitters with timely and transparent information.

Data Quality Assurance

Data Quality Assurance (DQA) is enterprise-wide and affects all data we collect, store, share and use in some way.

One focus of the team is to ensure that data used internally and externally has been quality assured in line with corporate requirements and statutory obligations, promoting consistency in the management and use of DQA processes and tools across the organisation to achieve this.

Overarching assurance helps to ensure that DQ requirements are met, there are no gaps in provision, and duplication of work is avoided.

Updates

Experimental Tobacco and Alcohol Dependency Data Quality Maturity Index (DQMI)

As part of continued work to expand the depth of reporting of the DQMI across datasets work has been undertaken with the Tobacco Dependence and Alcohol Dependence Programmes to add a specific dashboard to help drive data quality in these areas. This dashboard will allow providers to assess their performance. 

Access the Power BI.

This report is intended to complement the tobacco and alcohol dependence patient level dashboards on FutureNHS (registration required). 

Expansion to MHSDS DQMI (Updated 22 April 2024)

As part of continued work to expand the depth of reporting of the DQMI across data sets, work has been undertaken with NHS England and the MHSDS analysis and collection teams to expand the DQMI by a further 22 data items following the release of the MHSDS version 5 in October 2021.

An experimental version of the DQMI, which includes the expanded list of experimental data items, is currently included within the publication.  The experimental data items do not contribute to the official DQMI score.

MHSDS 36 Item DQMI contributes to overall DQMI score

MHSDS 62 Item DQMI contributes to experimental DQMI score only

*Note the GENDER IDENTITY CODE is the new priority item on gender, but PERSON STATED GENDER data item has been retained to support providers transitioning to submitting gender identity code. We have provided additional guidance on collecting and submitting data for the data items on gender to support organisations and users to implement the Mental Health Services Data Set (MHSDS) v5.0.

For more detail on new data item codes, please see the MHSDS v4.1 to v5.0 mapping guidance.

Expansion to CSDS DQMI reporting

We are no longer able to update this CSDS UCR and MSK DQMI report beyond the March 2024 data. Please see the CSDS DQ Dashboard to access more recent information relating to the general data quality of the CSDS.

This report, undertaken by NHS England and the CSDS Analysis and Collection teams, provides further detail on the UCR and MSK data within the CSDS DQMI to help drive data quality improvements in these areas. The table below details the criteria for records and the data items reported.

Provider Data Quality Assurance Framework

The Provider Data Quality Assurance Framework is aimed at provider organisations who, in terms of data quality assurance, need to get started and those that are looking to build on their existing data quality assurance processes and practices.  

The framework covers 5 main themes:

  • oversight
  • process
  • people
  • systems
  • measures

Each part of the framework also includes an Assurance Checklist to assist provider organisations to assess where they are in terms of data quality assurance and what gaps there might be that the framework can help fill.

The framework can be accessed here:

The framework has been developed to meet the requirements of the Data Security and Protection Toolkit and to support the published technical guidance.
