Commissioners in south-west London are delaying significant cuts to the income of some overfunded GP practices in Wandsworth and Croydon to avoid “destabilising” them.

NHS Croydon and NHS Wandsworth have reviewed and decided on changes in funding to their GP practices with personal medical services contracts.

Practices with PMS contracts are often paid larger sums for providing similar services to others, and the National Association of Primary Care last week complained about cuts now being made to those practices across the country.

A report to the NHS South West London primary care trust cluster’s board said it had previously agreed “a financial and transition negotiating position” for changes. It said: “The team is now close to preparing and sending out formal offers to the practices in both boroughs.”

However, it added that discussions had led to it being “agreed that transition could extend by a further 12 months for those practices that would see a reduction of 20 per cent or more under the newly negotiated arrangement”. The report said: “This was consistent with the boards’ desire not to destabilise practices unnecessarily.”

An equalities impact assessment found the income changes overall would mean an “increased level of investment in the 25 per cent of practices with highest index of multiple deprivation” and “a positive impact” on inequalities.
