Value Cases in development

Chest X-Ray AI

in March 2024, the Innovation Design Authority approved the strategic case for implementing artificial intelligence (AI) to identify high-risk chest x-rays (CXRs).

The AI aims to flag high-risk CXR images in the lung cancer pathway, helping clinicians prioritise patients for CT scans. This could streamline diagnosis and treatment, improving patient outcomes.

Obstructive Sleep Apnoea and Hypopnea Syndrome (OSAHS) Wearable Devices 

In December 2025, the Innovation Design Authority approved the Strategic Case for implementing wearable devices to diagnose OSAHS.

Wearable technology has the potential to transform sleep services across Scotland by supporting earlier diagnosis and improving access to care. Poor sleep is associated with a range of adverse health outcomes and, by refining treatment pathways and regional service delivery models, a sustainable national approach could improve patient quality of life while reducing pressure on NHS resources.

Chest X-Ray A CT Coronary Angiogram (CTCA)

In April 2026, the Innovation Design Authority approved the Strategic Case for increasing CTCA capacity and achieving universal coverage across NHS Scotland.

Coronary Artery Disease (CAD) is one of the leading causes of death in Scotland, and disproportionately affects people living in deprived areas. CTCA is a specialised scan that allows doctors to look inside the heart's blood vessels without the need for an invasive coronary angiogram. CTCA is highly accurate in diagnosing CAD in patients with stable chest pain. Despite this, access to CTCA is inconsistent, with patients in some areas facing long waits or offered alternative diagnostic tests which are not as accurate.

Delivering equitable CTCA access has the potential to improve patient outcomes through quicker, more accurate diagnosis. This could particularly benefit patients living in areas of greater socioeconomic deprivation.
