Commissioners of NHS services have a fixed budget from which they must pay for services to meet health needs that are growing and changing (for example, as the population gets older). Sometimes new and better treatments that could replace what is currently being offered become available. This means commissioners must prioritise, making decisions about which services to continue to fund, start to fund, or stop funding (sometimes known as ‘disinvestment’).

DMAT is based on research about:

  • The processes that make decisions about priorities legitimate and acceptable to people.
  • The place of social values in health priority setting.
  • How commissioners or funders of services – such as NHS clinical commissioning groups (CCGs) in England – make these decisions in practice.

The contents and concept of DMAT have been tested with a number of CCGs and patient and public representatives in England. This prototype online version will be tested more widely. There are also plans to see whether such an online tool would be useful in other countries with different health systems, governance, and ways of involving people in decisions about health priorities.

The research has been funded by CLAHRC South London and King’s College London.

We have created a film about the complexities of setting fair priorities for health care using the example of cancer treatment funding in the UK devolved nations, which you can watch below.

Priority-setting in health aims to determine what, in the context of limited resources, is most important.

This current version of DMAT is a prototype for testing only. We welcome feedback on all aspects of the tool so that future versions are as helpful and easy to use as possible. Please send any comments you have to the research team via

We already have plans to extend and improve DMAT in a number of ways. In addition to any comments of your own, we are very interested to hear from you about the following:

Overall usefulness

  • Did you find DMAT useful and how did you use it?
  • What could be improved to make it more useful for you or your organisation?

Content and language

  • Do the domains cover the right topics to help you make good decisions?
  • Are the main questions helpful and easy to understand?
  • Are the prompt questions helpful when it comes to answering the main questions?


  • How do you find using the tool? Is it intuitive and easy to use?
  • What works well? What could be improved?
  • Are the reports useful and easy to understand?
