NHS Scotland, sometimes styled NHSScotland, is the publicly funded healthcare system in Scotland and one of the four systems that make up the National Health Service in the United Kingdom. It operates 14 territorial NHS boards across Scotland, 7 special non-geographic health boards, and NHS Health Scotland. At the founding of the National Health Service in the United Kingdom, three separate institutions were created in Scotland, England and Wales and Northern Ireland. The NHS in Scotland was accountable to the Secretary of State for Scotland rather than the Secretary of State for Health as in England and Wales. Prior to 1948, a publicly funded healthcare system, the Highlands and Islands Medical Service, had been established in Scotland in 1913, recognising the geographical and demographic challenges of delivering healthcare in that region. Following Scottish devolution in 1999, health and social care policy and funding became devolved to the Scottish Parliament. It is currently administered through the Health and Social Care Directorates of the Scottish Government. The current Cabinet Secretary for Health and Social Care is Humza Yousaf, and the head of staff is the director-general health and social care and chief executive of NHS Scotland, Caroline Lamb. Budget NHS Scotland had an operating budget of £15.3billion in 2020-21. Health and social care are devolved issues in the United Kingdom and the separate public healthcare bodies of Scotland, England and Wales are each commonly referred to as "National Health Service". The NHS in Scotland was created as an administratively separate organisation in 1948 under the ministerial oversight of the Scottish Office, before being politically devolved in 1999. This separation of powers and financing is not always apparent to the general public due to the co-ordination and co-operation where cross-border emergency care is involved.
