The minimum practice income guarantee was introduced at the last minute to prevent meltdown in general practice as a result of problems related to the Carr-Hill formula, which determines practice funding, writes Neil Thomas

The formula itself was robust, but a variety of reasons accounted for this anomaly.

My own practice is in a deprived part of Cheshire with a young population. The guarantee accounts for about 7 per cent of total practice income and without it, our continued existence in an area crying out for good primary care would be put at risk. Removing the guarantee, when it was promised for perpetuity, will result in a poorer service.
