Reviews of NHS health care in England and Wales – overview
146.In relation to NHS health care in England and Wales, responsibility is divided between the CHAI and the Assembly. The Assembly remains primarily responsible for reviewing the provision of health care by and for NHS bodies in Wales (Chapter 4). CHAI has responsibility for reviewing the provision of health care by and for NHS bodies in England and cross-border Special Health Authorities (Chapter 3). However, CHAI also has some functions relating to the review of the overall provision of health care across England and Wales (see sections 49 and 51); and could in the future be given further functions relating to England and Wales (section 58).
