Successive DH ministerial teams have been criticised for repeated reorganisations of the NHS in England, where primary care commissioning responsibility, in particular, has been allocated to four different sets of organisations in the last ten years: PCGs, small area Primary Care Trusts (PCTs) (e.g. covering a rural local authority district or part of a city), larger-area PCTs (e.g. covering a whole county), PCT clusters (e.g. quarter of London or South of Tyne and Wear) and the currently unspecified Clinical Commissioning Groups. The tendency to introduce each reorganisation before its predecessor has had time to settle down and generate improved performance has attracted censure amongst healthcare professions in the UK and beyond, including reference to the ironic concept of 'redisorganization'.
