Delivery of frontline healthcare services in Scotland are the responsibility of 14 regional <a href='https://www.scot.nhs.uk/' target='_blank' rel='nofollow ugc noopener noreferrer'>National Health Service (NHS)</a> Boards that report to the Scottish Government. Current boundaries of NHS Health Boards in Scotland are defined by National Health Service (Variation of Areas of Health Boards) (Scotland) Order 2013 (SSI 2013/347), which came into force on April 1st 2014, and replaces the previous definition based upon the former Regions and Districts of the Local Government (Scotland) Act 1973. This change was made in order to re-align Health Boards with the combined area of each Local Authority that they serve. Subsequent changes to Local Authorities will result in corresponding amendments to Health Board boundaries in order to maintain alignment.
