What do we known about fundholding in general practice?

The general practice fundholding scheme was introduced four years ago. So far its impact has not been formally evaluated nationally, but review of published research shows some trends. Fundholding has curbed prescribing costs and given general practitioners greater power to lever improvements in hospital services--for example, reducing waiting times for hospital treatment--but fundholding practices may have received more money than non-fundholding practices. The impact of fundholding on transactions costs, equity, and quality of care (particularly for patients of non-fundholding general practitioners) is unknown. Research into costly reforms such as fundholding needs to be coordinated.
