NICE quality standards describe high-priority areas for quality improvement in a defined care or service area. Each standard consists of a prioritised set of specific, concise and measurable statements. They draw on existing guidance, which provides an underpinning, comprehensive set of recommendations, and are designed to support the measurement of improvement.

This quality standard covers the assessment, diagnosis and specialist referral of adults and young people (aged 16 and older) who have experienced a transient loss of consciousness.
