Under the Scottish Government’s flagship eHealth Strategy 90 per cent of surgeries are supposed to offer such digital services by the end of this year.
But new research has revealed just four health boards have reached the goal despite pledges to use technology to bolster frontline care.
Think-tank Reform Scotland found only a quarter of NHS Highland practices offer online appointments booking and/or repeat prescribing.
This stood at 45 per cent in Ayrshire and Arran and 50 per cent in Shetland, according to figures released in response to a freedom of information request.

Research director Alison Payne added: “The Scottish Government and the Royal College of General Practitioners have recognised the benefit of offering more services, such as repeat prescriptions and booking appointments, online.
“Yet it is clear from these figures that too few people can benefit from these…
