The aim of the awards is to celebrate innovation in general practice and promote ideas that can be easily adopted by other UK surgeries.
Thamesmead Medical Associates, in Greenwich, won the Outstanding Practice Team award, worth £1,000. It went on to beat the five other section winners in a poll of GP readers to scoop the £4,000 first prize and the MDU Enterprise Award.
Dr Eugenia Lee, the practice's public health lead who came up with the idea for the scheme, said: 'We're absolutely thrilled. Being visible in the community gives out the positive message that the NHS is not just about firefighting, but also about prevention.'
The practice set up health checks at its local supermarket, screening 1,024 men over eight Saturdays. The checks included BP, random blood glucose and BMI, with spirometry offered to smokers. Of those screened, 424 were offered follow-up for one or more abnormal readings, 325 of whom had no previously diagnosed disease.
