Track NHS diagnostic tests waiting times in Scotland

Consultants looking at result from a MRI scan on a brain and a bar chart which symbolises diagnostic waiting times in scotland

There are not many things in life more stressful than waiting for a diagnosis.

Once a diagnosis is given the work can begin on treatment or learning to live with a condition, but you can’t begin that step until you’ve received diagnostic tests.

With that in mind we’ve put together a selection of charts laying bare the current waiting times for NHS diagnostic tests.

We will update the charts when new data is available.

The key diagnostic tests covered in this article are barium studies, colonoscopy, CT, cystoscopy, lower endoscopy, MRI, and non-obstetric ultrasound.

What is the target for diagnostic waiting times in Scotland?

The Scottish Government has set a target that for the eight key diagnostic tests, patients should wait no longer than six weeks.

Although Covid-19 has had an impact on diagnostic waiting times in Scotland, a report by Public Health Scotland shows the number of Scots waiting for diagnostic tests is 75% higher than the average in the 12 months prior to the pandemic.

Barium study waiting times

Barium studies involve ingestion of a substance called barium which shows up on x-rays as a contrast and assists in diagnosis.

The chart below shows the available data on waiting times for barium studies across NHS Scotland health boards.

Use the dropdown to find the area you are interested in.

Upper endoscopy waiting times

Upper GI endoscopy involves using a small camera to see the lining of the upper GI tract.

It can be used to investigate the cause of problems such as heartburn, bleeding, nausea, and difficulty swallowing.

The chart below shows the available data on waiting times for upper endoscopy across NHS Scotland health boards.

Use the dropdown to find the area you are interested in.

Colonoscopy waiting times

Colonoscopy involves the use of a small, flexible camera which is used to investigate the health of the bowels.

Patients will be provided with a laxative preparation prior to the test which ensures the bowels are empty for the test.

The chart below shows the available data on waiting times for colonoscopies across NHS Scotland health boards.

CT waiting times

CT stands for computerised tomography and it is a diagnostic scan that uses both x-rays and computer imaging to create a detailed picture of the inside of the body.

They are carried out in hospitals by specially trained radiographers.

CT scans can be used to diagnose conditions such as strokes or injuries to internal organs.

The chart below shows the available data on waiting times for CT scans across NHS Scotland health boards.

Cystoscopy waiting times

Cystoscopy uses a thin camera called a cystoscope to look inside the bladder.

Cystoscopy can be used to diagnose urinary tract issues such as infections, trouble urinating or pelvic pain.

The chart below shows the available data on waiting times for cystoscopy across NHS Scotland health boards.

Use the dropdown to find the area you are interested in.

Lower endoscopy waiting times

Endoscopy is another test that involves passing a small camera into the body.

It can be used to help diagnose abdominal pain and can detect abnormalities such as inflammation, infection or ulcers.

The chart below shows the available data on waiting times for lower endoscopy across NHS Scotland health boards.

MRI waiting times

It is a type of scan that uses magnetic fields and radio waves to create detailed images of the inside of the body.

Perthshire professor James Hutchison developed the scanner while working at Aberdeen University in 1980.

MRI scans can be used to look at almost any part of the body and will be carried out by a radiographer.

The chart below shows the available data on waiting times for MRI scans across NHS Scotland health boards.

Non-obstetric ultrasound waiting times

Non-obstetric ultrasound is a non-invasive procedure that scans the body to aid in diagnosis.

Ultrasound devices use a probe that emits high frequency sound waves.

The waves then ‘bounce’ off the relevant part of the body and is then turned into a moving image.

The chart below shows the available data on waiting times for non-obstetric ultrasound scans across NHS Scotland health boards.
