How the NHS will change in England
The NHS in England is in the middle of the biggest reorganisation since its creation.
At the moment, 152 bodies called primary care trusts (PCTs) control local spending on dentists, hospital operations and tests, and medicines - accounting for 80% of NHS spending.
From April 2013 PCTs will be replaced by more than 200 GP-led organisations called Clinical Commissioning Groups (CCGs) which will be responsible for closer to 60% of the NHS budget.
Branwen Jeffreys explains how the government's changes to the NHS will affect patients and how the health service is run.
