A Holyrood health committee is looking into what out-of-hours GP services residents in rural areas receive.
Senior NHS representatives will be quizzed by MSPs after residents campaigned against a decision by NHS Tayside to remove 24-hour local GP cover.
At a meeting in Loch Rannoch, Perthshire, MSPs will gather evidence from NHS Tayside, NHS 24, the Scottish Ambulance Service and residents from Kinloch Rannoch.
Six years ago, doctors were given the choice about whether to offer round-the-clock care, with services such as helpline NHS 24 standing in as an alternative if GPs chose not to offer a 24-hour service.
Local residents believe the alternate services cannot replace traditional GP care, but the health authority said the issue was still a priority and insisted the options available to the region were reliable and safe.
