Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment his Department has made of the implications for his Department's policies of the document published by Euroqol entitled EQ5D-5L value set for the United Kingdom, published on 13 March 2026.

The National Institute for Health and Care Excellence (NICE) is planning to adopt the EQ-5D-5L and has opened a consultation on the proposed changes to its guidance development manuals.

The consultation opened on 15 April and includes the proposed changes to NICE’s guidance development manuals and the results of two impact assessments, looking at how the EQ-5D-5L value set might affect:

• the outputs of the cost-effectiveness models that NICE uses in its evaluations, including estimates of quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios; and
• the number of decisions qualifying for the severity modifier, and how it changes absolute and proportional QALY shortfall estimates.

NICE has also considered the potential impact of these proposed method changes on equalities and health inequalities, and it is inviting views on its conclusions.
