NHS 24 is Scotland's national telehealth and telecare organisation. This special health board runs a telephone advice and triage service that covers the out-of-hours period (Mondays to Fridays between 6pm and 8am, public holidays and all weekend). The telephone service allows people who feel unwell or those caring for them to obtain health advice and information if it is not convenient or possible to wait until they can visit their general practitioner when the practice is next open. The advice line is not intended as a substitute for obtaining an emergency ambulance service via 999. The telehealth services provided by NHS Scotland fulfil some similar functions to NHS Direct Wales and the NHS 111 scheme in England.
