Weighting of GP practice funding is 'inequitable', finds study

GP practices in the north of England should be receiving higher funding than they do under current weighting, researchers have suggested.

A University of Manchester-led study, published in BMC Medicine, found that the Carr-Hill formula for weighting GP practice funding based on local health needs was 'inaccurate' and 'out of date'.

The research, partly funded by the Medical Research Council, aimed to examine whether primary care funding in 2015/16 matched healthcare needs at geographical areas with an average of 1,500 people.

Looking at data from 7,779 GP practices in England - covering nearly 57m people or 99% of the GP practice-registered population - the team created a new chronic morbidity index (CMI).

This was calculated as the sum of 19 chronic condition registers in the 2014/15 QOF framework, divided by the total practice population.

The analysis found that London has a median of 0.38 health conditions per patient - the lowest in the country - while the highest and second highest health needs were found in North East and North West of England (at 0.59 and 0.55 conditions per patient respectively).

The paper said: 'Levels of morbidity varied within and between regions, with several clusters of very high morbidity identified. At the regional level, morbidity was modestly associated with practice funding, with the North East and North West appearing underfunded.

'The regression model explained 39% of the variability in practice funding, but even after adjusting for covariates, a large amount of variability in funding existed across regions.

'High morbidity and, especially, rural location were very strongly associated with higher practice funding, while associations were more modest for high deprivation and older age.'

The Carr-Hill formula has been in place since 2004 but has been subject to an on-off review since 2007. It has frequently been criticised for not sufficiently taking into account deprivation.

Lead researcher Professor Evangelos Kontopantelis, from the University of Manchester, said: 'If as a society we want a healthcare system which is fair, then we must fund it according to need, and ideally account for the impact of deprivation.

'This study shows that the current allocation of resources to primary care does not do that.'

Tim Doran, professor of health policy at the University of York and co-author of the study, said: 'The present funding formula does not provide an equitable distribution of resources across the NHS. It is especially unfair to the North West and North East of England.

'The Carr-Hill formula, which is used to allocate NHS funding, is based on a range of data, some of which are inaccurate, unrepresentative or out of date. As a result, the formula does not accurately reflect the health care needs of local populations.

'New data sources could provide a fairer allocation of resources.'
