Chief Medical Officer (United Kingdom)
The Chief Medical Officer (CMO) is the most senior advisor on health matters in a government. There are four CMOs in the United Kingdom who are appointed to advise their respective governments: Her Majesty's Government, the Northern Ireland Executive, the Scottish Government and the Welsh Government. Each CMO is assisted by one or more Deputy Chief Medical Officers, and are complimented by a Chief Nursing Officer.
In England, the CMO is a member of the board of the National Health Service (NHS), a civil servant in the Department of Health, and head of the medical civil service. The Republic of Ireland has a similar officer.
The Chief Medical Officer is a qualified medical doctor whose medical speciality traditionally was public health medicine, and whose work focused on the health of communities rather than health of individuals. More recently the appointees have been clinicians without training or experience in public health medicine. In the UK, the CMO is one of six chief professional officers who advise the government in their respective health and social care disciplines.
The equivalent US term is Surgeon General. The term Surgeon General is also a used in the British Armed Forces for the head of medical services. In non-government organisations, such as policing, chief medical officer may refer to a senior medical post in the organisation. When appointed outside government the chief medical officer will often decide on physical and mental fitness to serve issues, and the role may not be in public health.
Chief Medical Officers for Her Majesty's Government
The historic post was created in Victorian times to help to prevent cholera epidemics. In 1969 the post of Chief Medical Officer for Wales was created, and prior to this both England and Wales were covered by the post of Chief Medical Officer of England and Wales.
