GP Practice Lists
The question
To ask the Secretary of State for Health and Social Care, pursuant to the Answer of 20 March 2025 to Question 37767 on GP Practice Lists, what weighting does the Carr-Hill Formula give to patient deprivation.
Answered by Stephen Kinnock
The Carr-Hill formula does not include a weighting for patient deprivation. Amongst the range of factors included in the formula, the proportion of the population with a limiting long-term illness (LLTI) and the standardised mortality ratio (SMR) for those aged under 65 years old (SMR<65) are correlated with higher deprivation. The weightings for these factors are the practice list multiplied by (48.1198 + (0.26115 multiplied by the practice’s LLTI) + (0.23676 multiplied by the practice’s SMR<65)).
