Reduced consciousness
Assess a patient with reduced consciousness without assuming the cause from their first appearance.
Clinical learning outcomes: Awaiting named clinical review.
What you should learn
- Identify threats to airway, breathing and circulation and seek immediate help.
- Build a differential using history, examination and bedside results.
Recognise and explain
- Consider neurological, metabolic, toxicological and traumatic causes.
On your placement
Agree your role with the supervising clinician and discuss consent and capacity before any patient-facing learning.
- Take a collateral history and document timing.
- Practise consciousness assessment and capillary glucose measurement with supervision.
- Present findings and discuss monitoring and the next investigation.
Observe and understand
- Observe specialist airway protection or critical-care escalation.
Observation does not establish competence to perform these activities.
The poisoning lesson explores one cause of reduced consciousness; keep the wider differential in mind.
Start here
MLA: assess, act and reassess
Use a structured assessment and call for appropriate help.
MLA: substance history and urgent illness
Read why abnormal physiology or reduced consciousness must not simply be attributed to alcohol.
Discuss
Initial assessment of suspected poisoning
Approach an uncertain ingestion with supportive care, targeted information and physical and psychosocial safety in parallel.
On your next shift
Name one reversible cause considered early and how the team assessed it.

Optional material. Advanced resources extend discussion; they do not define independent student practice. Check the publication date and compare clinical advice with current guidance.
RCUK adult advanced life support 2025
Optional background on the resuscitation team’s decisions, reversible causes and advanced treatment; these are not independent student tasks.
GMC: procedure supervision and graduate requirements
Check the competence and supervision level for a procedure; agree what you can practise with your placement supervisor.
NICE: reduced consciousness following head injury
Use the age-appropriate head-injury assessment sections when injury may explain the reduced consciousness.
How this relates to GMC graduate outcomes and the MLA
These are St Emlyn’s learning connections, not a claim that this page covers every national requirement.

Clinical and professional capabilities: Assessment and clinical reasoning; Recognising limits and seeking help.
Practical skills: Consciousness assessment; Capillary glucose measurement.

About this resource and its review
A St Emlyn’s guide to learning Emergency Medicine during undergraduate placements. It is not an official medical-school or GMC curriculum. Your medical school’s curriculum and assessment requirements take precedence.
National foundations: GMC Outcomes for Graduates, the practical-skills supplement and the MLA content map applying from September 2026.
Framework checked: 8 October 2026. This is a source check, not clinical sign-off.
Clinical learning outcomes: awaiting named clinical review.
The four learning routes are St Emlyn’s groupings. The six interconnected MLA domains remain part of the official content map.
