The Health and Social Care Act 2012 is a piece of legislation in the United Kingdom that aimed to reform the National Health Service (NHS). It introduced changes to how health services are organized and delivered, promoting competition among providers and giving more power to local authorities in managing health care. One of the key features of the Act was the establishment of Clinical Commissioning Groups (CCGs), which are responsible for planning and purchasing health services in their areas. The Act also emphasized the importance of patient choice and aimed to improve the quality of care by encouraging innovation and efficiency within the NHS.
