Galloway and West Dumfries MSP Finlay Carson has expressed his concerns over patients being given false guaranteed treatment times as they wait for operational assessments.
The Scottish Conservative and Unionist MSP has written to SNP Government Health Secretary Jeane Freeman after being contacted by concerned constituents over information given to them on treatment guarantees.
With the SNP Government setting a 12 week target of being seen to starting treatment, many dates are given to patients which are never met.
In one particular case raised with Mr Carson, a patient was given a "guaranteed time" of September 24 for a pre-assessment, but is now having to wait two months longer.
Mr Carson says that with pressures already on GP services, accurate information is absolutely vital for rural patients and staff.
Commenting, Finlay Carson MSP said: "Waiting for assessments and treatment is a hugely stressful time for patients, so they cannot be given false hope over when this will happen.
"While I understand the SNP Government's desire to hit target times, delays are often commonplace and that information should be relayed to patients straight away.
"Those that have contacted me thought they would be getting assessments done on a certain date but are now waiting weeks and months for this to happen, leaving them angry.
"I hope that the Health Secretary can take these concerns seriously and address literature that is given to patients, ensuring that they receive information about any delays in a timely fashion."
