Unexpected deterioration during possible dying
A person thought to be dying may instead have hypoglycaemia, opioid toxicity, urinary retention, sepsis, haemorrhage, spinal compression or another reversible emergency. A sudden change inconsistent with the trajectory requires prompt reassessment.
Action: Use a proportionate ABCDE and bedside glucose assessment, review recent medicines and examine for pain, retention, impaction, bleeding and focal neurological or infective signs. Treat immediately reversible distress within the agreed ceiling, seek senior review and revise the last-days plan if recovery remains plausible.
Synopsis
Recognise when a person may be entering the last days, test proportionate reversible explanations, communicate uncertainty honestly and replace burdensome routine care with an individual symptom, family, spiritual and practical plan that remains under review.
Dying is a clinical judgement based on trajectory, disease, function and a cluster of signs; no single observation, score or test proves that death is imminent.
Common changes include becoming bedbound, profound weakness, reduced desire or ability to eat and drink, increasing sleep, reduced urine, altered breathing and peripheral cooling.
First-line review asks whether infection, hypercalcaemia, medicine toxicity, hypoglycaemia, retention, constipation, bleeding or another reversible problem explains the change and whether treating it matches the person's goals.
Key red flags
Abrupt reduced consciousness after opioid escalation or kidney decline suggests toxicity rather than inevitable dying.
Unexpected acute deterioration
Abrupt collapse, severe new pain, bleeding, hypoglycaemia or medicine toxicity may be reversible and requires immediate goal-based assessment rather than automatic dying diagnosis.
Investigation priorities
01
First-line trajectory assessmentFirst stepFirst line
Compare mobility, self-care, wakefulness, intake, swallowing, urine, symptoms and treatment response over recent days and weeks.
02
Communication and plan auditPreferred
Confirm who has been told, information preferences, escalation, preferred place, anticipatory medicines and cultural or spiritual needs.
Management branches
RecognitionSynthesize trajectory and reversible causes
A person with advanced illness shows progressive functional, intake, consciousness, circulation or breathing change.
Compare the current state with recent baseline and seek nursing, family and disease-team observations, then assess symptom burden and immediate safety.
Check proportionate reversible explanations such as glucose, medicines, retention, constipation, infection, calcium and bleeding according to goals.
Individual planReplace low-value routine with comfort-focused care
The person is likely in the last days and the plan prioritises comfort and chosen relationships.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
