This report outlines the challenges faced by general practice in London and the improvements needed in order to address them. The report is aimed at those who have a role in leading quality improvement in primary care, namely GPs working in London and leaders of primary care providers, clinical commissioning groups (CCGs), and the London region of the NHS Commissioning Board. Prepared by The King’s Fund and Imperial College London, it provides an independent assessment of the quality of general practice in the capital, using routinely available data sources.
