📋 Key Information Summary
- Recognising deterioration allows timely preparation, communication with patient and family, anticipatory prescribing, and optimal comfort care in the last days of life.
- The deteriorating phase (weeks to days before death) is characterised by increasing fatigue, reduced oral intake, declining function, and increased sleep; it is distinct from the terminal phase.
- The terminal phase (hours to days) is identified by combinations of semi-coma, Cheyne–Stokes respiration, inability to take oral medications, peripheral shutdown, and agitation or restlessness.
- The Australia-modified Karnofsky Performance Status (AKPS) is the standard functional assessment tool used by Australian palliative care services to track decline and guide decision-making.
- An AKPS score ≤30 typically indicates the terminal phase; scores of 40–50 suggest significant deterioration with increasing care needs.
- Peripheral shutdown — cool extremities, mottling (livedo reticularis), cyanosis of fingers/toes, and prolonged capillary refill — is a reliable physical sign of impending death, often appearing 24–48 hours prior.
- Anticipatory prescribing of subcutaneous (SC) syringe drivers containing morphine (pain/dyspnoea), midazolam (agitation/seizures), haloperidol (nausea/delirium), and hyoscine butylbromide (respiratory secretions) is essential for managing the terminal phase.
- All non-essential medications (statins, antihypertensives, oral supplements) should be reviewed and ceased as the patient approaches death to avoid unnecessary burden.
- Clear, compassionate communication with families about expected signs of dying — changes in breathing pattern, skin colour, consciousness — reduces distress and enables a supported death.
- Aboriginal and Torres Strait Islander communities may have culturally specific requirements around Country, sorry business, and the presence of particular family members; early engagement with Indigenous health workers is essential.
- Children and young people require age-appropriate explanations; paediatric palliative care services (e.g., Bear Cottage, Very Special Kids) should be engaged early.
- Formal recognition of dying — documented in the clinical record with a clear management plan — should occur promptly to ensure appropriate care and medication availability.
Introduction & Australian Epidemiology
Recognising when death is approaching is one of the most important clinical skills in palliative medicine, general practice, and hospital-based care. Timely identification of the dying trajectory allows clinicians to shift the focus of care from disease-directed treatment to comfort, symptom management, and psychosocial support for both the patient and their family or carers.
In Australia, approximately 178,000 people die each year (2022 data), with around 70% of deaths occurring in people aged 65 years and older. Despite the majority of Australians expressing a preference to die at home, approximately 54% of deaths still occur in acute hospitals, 20% in residential aged care facilities (RACFs), and only 16–18% at home. The National Palliative Care Strategy (2018) and Palliative Care Australia's National Palliative Care Standards (5th edition, 2018) emphasise the importance of recognising dying as a discrete clinical event requiring a structured response.
Failure to recognise the terminal phase leads to inappropriate investigations, continued burdensome treatments, delayed anticipatory prescribing, and avoidable distress for patients and families. Conversely, premature labelling of a patient as dying can result in under-treatment of reversible conditions — a careful, systematic approach is required.
This article covers the clinical trajectory from the deteriorating phase through to the terminal phase, the role of functional assessment tools (particularly the AKPS), the physical signs of peripheral shutdown, and practical management including anticipatory prescribing, communication strategies, and care of special populations in the Australian context.
Deteriorating Phase
The deteriorating phase typically spans weeks to days before death and represents a period of progressive functional decline. Patients and families often describe a "gradual winding down." Recognition of this phase is critical for initiating advance care planning discussions, involving specialist palliative care, commencing anticipatory medications, and ensuring appropriate supports are in place.
Clinical Features of the Deteriorating Phase
| Domain | Features | Clinical Significance |
|---|---|---|
| Performance status | Declining AKPS (40–50 range); increasing time in bed or chair; requiring assistance with most ADLs | Progressive functional decline is the strongest predictor of approaching death |
| Oral intake | Decreased appetite and fluid intake; anorexia; early satiety; preference for small, soft meals | Anorexia of advanced disease is expected; forced feeding is not recommended and may cause distress |
| Consciousness | Increasing drowsiness; sleeping more; periods of confusion or delirium; reduced engagement | Delirium prevalence approaches 80–90% in the last week of life |
| Weight and nutrition | Cachexia; muscle wasting; loss of subcutaneous fat | Cancer cachexia and disease-related malnutrition are common and largely irreversible |
| Pain | May increase or become more difficult to assess if communication declines | Regular reassessment is essential; rely on observational pain tools when verbal communication is lost |
| Psychosocial | Withdrawal from social activities; existential distress; "unfinished business"; reviewing life | Referral to psychosocial support services (social work, chaplaincy, counselling) should be offered |
| Infections | Recurrent or non-resolving infections; increasing antibiotic courses | Consider whether further antibiotic courses serve the patient's goals of care |
Key Actions in the Deteriorating Phase
Terminal Phase
The terminal phase (also termed the actively dying or last days of life phase) is defined as the period when death is expected within hours to a few days. The Gold Standards Framework (UK, widely adopted in Australia) defines this as the "final hours or days of life." Recognition of the terminal phase is a clinical decision based on the overall trajectory rather than any single sign.
Diagnostic Criteria for the Terminal Phase
A patient should be considered in the terminal phase when two or more of the following are present in the context of an advanced, progressive, life-limiting illness:
- Semi-coma or deeply unconscious state (unrousable or only briefly rousable)
- Inability to take oral medications or fluids
- Cheyne–Stokes breathing pattern (crescendo–decrescendo breathing with apnoeic pauses)
- Peripheral shutdown (cool, mottled, cyanotic extremities)
- Audible respiratory secretions ("death rattle") unresponsive to positioning or anticholinergic medications
- No urine output or minimal output (<100 mL in 12 hours in the absence of obstruction)
- Myoclonic jerking
- Restlessness or terminal agitation not explained by reversible causes
Recognising the Transition
The transition from the deteriorating phase to the terminal phase is often marked by a noticeable change in consciousness and oral intake. Families may report that the patient "seems different today" or "is no longer really here." Clinicians should document this transition formally, update the care plan to reflect comfort-focused management, and ensure all team members (including after-hours services, RACF staff, and ambulance services where applicable) are aware.
Management Principles in the Terminal Phase
Managing Specific Terminal Symptoms
| Symptom | First-Line Management | Second-Line / Refractory |
|---|---|---|
| Pain | Morphine SC via syringe driver (if opioid-naïve: 10–30 mg/24 h CSCI) with PRN doses of 2.5–5 mg SC q4h | Fentanyl SC, methadone SC, ketamine SC (specialist input). Consider adjuvants: dexamethasone for bone pain, gabapentin for neuropathic pain if able to administer. |
| Agitation / Delirium | Midazolam SC 2.5–10 mg/24 h CSCI; haloperidol SC 2.5–5 mg/24 h CSCI | Levomepromazine SC 12.5–50 mg/24 h CSCI; clonazepam SC 0.5–1 mg/24 h CSCI; phenobarbitone (specialist use). |
| Respiratory Secretions | Hyoscine butylbromide SC 60–120 mg/24 h CSCI; repositioning (lateral/recumbent); gentle oropharyngeal suction PRN | Glycopyrrolate SC 0.2–0.4 mg q4h PRN. Note: hyoscine hydrobromide (0.4 mg SC q4h) causes more sedation — useful if concurrent agitation. |
| Dyspnoea | Morphine SC 2.5–5 mg q4h PRN or CSCI equivalent; fan / air movement; positioning upright if tolerated | Midazolam SC if associated anxiety. Consider bronchodilators only if known reversible airways disease and not in active dying. |
| Nausea / Vomiting | Haloperidol SC 0.5–2 mg q8h or CSCI; metoclopramide SC 10 mg TDS if gastric stasis suspected | Levomepromazine SC 6.25–12.5 mg q8h; cyclizine SC 50 mg q8h (may precipitate in syringe driver with other drugs). |
| Seizures | Midazolam SC 10–20 mg/24 h CSCI; PRN midazolam 5–10 mg SC q4h for breakthrough | Clonazepam SC; phenobarbitone SC (specialist advice). Consider prior anticonvulsant history. |
Australia-Modified Karnofsky Performance Status (AKPS)
The Australia-modified Karnofsky Performance Status (AKPS) is the standard functional assessment tool used by Australian palliative care services. It was developed by Abernethy et al. (2005) at Flinders University, Adelaide, as a modification of the original Karnofsky Performance Status (KPS) to better reflect the ambulatory and self-care domains relevant to palliative care populations. The AKPS is endorsed by Palliative Care Australia and used across all state and territory palliative care services for clinical assessment, research, and service planning.
AKPS Scale
| AKPS Score | Descriptor | Clinical Correlate | Phase |
|---|---|---|---|
| 100 | Normal; no complaints; no evidence of disease | Fully active, able to carry on all pre-disease activities without restriction | Stable / stable with some needs |
| 90 | Able to carry on normal activity; minor signs/symptoms | Active; minor restrictions | Stable |
| 80 | Normal activity with effort; some signs/symptoms | Requires occasional assistance but able to care for most needs | Stable |
| 70 | Cares for self; unable to carry on normal activity or do active work | Requires occasional assistance; unable to work | Stable with some needs |
| 60 | Requires occasional assistance; able to care for most needs | Needs help with some ADLs | Unstable |
| 50 | Requires considerable assistance and frequent medical care | Disabled; requires substantial assistance | Unstable |
| 40 | Disabled; requires special care and assistance | Mostly bed-bound or chair-bound | Deteriorating |
| 30 | Severely disabled; hospitalisation indicated (death not imminent) | Bed-bound; needs nursing care for most needs | Deteriorating / Terminal |
| 20 | Very sick; hospitalisation necessary; active supportive treatment needed | Bed-bound; needs total care | Terminal |
| 10 | Moribund; fatal processes progressing rapidly | Deeply unconscious; dying | Terminal |
| 0 | Dead | — | — |
Clinical Application of the AKPS
- Serial measurement: AKPS should be assessed at each clinical contact and documented in the clinical record. A declining AKPS over successive assessments (e.g., 60 → 40 → 20 over 2–4 weeks) is highly predictive of approaching death.
- Threshold for palliative care referral: An AKPS ≤50 in a patient with a progressive life-limiting illness should prompt specialist palliative care referral if not already involved.
- Terminal phase indicator: An AKPS ≤30 combined with other clinical features (reduced consciousness, inability to swallow, peripheral shutdown) strongly supports recognition of the terminal phase.
- Communication tool: AKPS provides a standardised language for discussing functional status with other clinicians, families, and multidisciplinary teams across primary, secondary, and tertiary care.
- Research and benchmarking: AKPS is collected by most Australian palliative care services for outcomes measurement and is used in the Palliative Care Outcomes Collaboration (PCOC) national dataset.
Peripheral Shutdown
Peripheral shutdown refers to the clinical signs resulting from the body's cardiovascular response to dying — the redistribution of blood flow from the periphery to vital organs (brain, heart, lungs) as cardiac output falls and systemic vascular resistance increases. It is one of the most reliable physical signs of impending death, typically appearing 12–48 hours before death, though the timeline is variable.
Clinical Signs of Peripheral Shutdown
- Cool peripheries: Hands and feet become cool to touch, progressing proximally over hours to the knees/elbows
- Mottling (livedo reticularis): Irregular, patchy, blue-purple discolouration of the skin, typically beginning on the knees and spreading
- Peripheral cyanosis: Blue-grey discolouration of nail beds, fingertips, and toes
- Prolonged capillary refill time: >3 seconds (compared to normal <2 seconds)
- Weakened peripheral pulse: Radial and dorsalis pedis pulses become difficult to palpate
- Decreased blood pressure: Systolic BP <90 mmHg may be present, but measurement is not recommended if the focus is comfort care
- Cardiac output falls as myocardial function declines
- Sympathetic vasoconstriction redirects blood to central organs
- Peripheral vasodilation occurs paradoxically in terminal shock
- Catecholamine surge may cause transient tachycardia followed by bradycardia
- Decreased circulating volume due to reduced oral intake and third-spacing
- The "centralisation" pattern is mediated by baroreceptor and chemoreceptor reflexes
Timeline of Peripheral Changes
Differentiating Peripheral Shutdown from Other Causes
| Condition | Features Distinguishing from Peripheral Shutdown |
|---|---|
| Sepsis / Distributive shock | Warm peripheries initially; fever; rigors; responding to fluids and antibiotics; in a dying patient, sepsis and peripheral shutdown may coexist |
| Dehydration | Dry mucous membranes; reduced skin turgor; concentrated urine — peripheral changes are less pronounced; responds to hydration if clinically appropriate |
| Heart failure exacerbation | Peripheral oedema; elevated JVP; pulmonary crepitations; may improve with diuretics — in the dying patient, heart failure may contribute to peripheral shutdown |
| Peripheral vascular disease | Chronic cool extremities; absent pulses; trophic changes; intermittent claudication history; changes are chronic rather than acute |
Clinical Presentation & Recognition Criteria
The recognition of dying is a clinical diagnosis based on the synthesis of multiple clinical features rather than any single test or sign. Several validated frameworks support this assessment in the Australian setting.
Supportive & Palliative Care Indicators Tool (SPICT)
The SPICT (University of Edinburgh, widely adopted in Australian general practice and RACFs) identifies patients with deteriorating health due to one or more advanced conditions for a palliative care approach. It includes general indicators (e.g., unplanned hospital admissions, weight loss, dependence on others for self-care) and disease-specific indicators.
Clinical Features Suggesting the Last Days of Life
Investigations
In the context of recognising when death is approaching, the role of investigations is limited. The primary purpose of any investigation should be to exclude reversible causes of deterioration before committing to a comfort-only care plan. Once the terminal phase is recognised, routine investigations should be ceased.
Anticipatory Prescribing
Anticipatory prescribing — the provision of injectable medications for breakthrough or escalating symptoms before they occur — is a cornerstone of quality end-of-life care. All patients recognised as deteriorating should have anticipatory medications prescribed and available, even if not yet in the terminal phase.
Medications to Cease in the Deteriorating/Terminal Phase
| Medication Category | Examples | Rationale for Cessation |
|---|---|---|
| Cardiovascular | Statins, antihypertensives, antiarrhythmics, anticoagulants (consider risk–benefit), antihypertensives | No benefit in terminal phase; may cause hypotension; swallowing difficulties. Anticoagulants: discuss risk of thromboembolism vs. bleeding risk — generally cease warfarin; DOAC cessation is recommended. |
| Diabetes medications | Oral hypoglycaemics (metformin, sulfonylureas, SGLT2 inhibitors), insulin (reduce/cease) | Hypoglycaemia risk with reduced intake. Cease metformin (lactic acidosis risk). Reduce or cease insulin; if continuing, monitor BSLs less frequently (comfort-focused). |
| Respiratory | Inhaled bronchodilators, inhaled corticosteroids, mucolytics | Inability to use inhalers; distressing; consider SC salbutamol only if bronchospasm is causing distress (specialist use). |
| Supplements | Vitamins, calcium, iron, potassium | No benefit; unable to swallow tablets; IV supplements unnecessary in terminal phase. |
| Gastrointestinal | PPIs, H2-receptor antagonists (oral), laxatives (oral), oral phosphate binders | Replace with SC alternatives if needed (e.g., ranitidine SC — note: currently unavailable in Australia; omeprazole via NG/PEG if present). Continue lactulose/enemas only if constipation is causing distress. |
| Antibiotics | Prophylactic antibiotics, long-term suppressive antibiotics | Infections are common in the dying; antibiotics may prolong dying without improving comfort. Discuss with patient/family. Therapeutic antibiotics may continue if infection is causing distressing symptoms (e.g., fevers, pain). |
Monitoring
Monitoring in the context of a patient approaching death should be symptom-focused rather than disease-focused. The purpose of monitoring shifts from tracking disease parameters (blood tests, vital signs, weight) to assessing and managing symptoms (pain, agitation, secretions, dyspnoea) and supporting the patient and family.
Monitoring Approach by Phase
Observational Pain Tools for Non-Verbal Patients
When a patient can no longer self-report pain (due to reduced consciousness), use an observational pain assessment tool:
- Abbey Pain Scale — recommended by Australian aged care and palliative care guidelines; assesses vocalisation, facial expression, change in body language, behavioural change, physiological change, and body condition. Score 0–18; ≥8 suggests moderate-to-severe pain.
- PAINAD (Pain Assessment in Advanced Dementia) — used in RACFs; assesses breathing, negative vocalisation, facial expression, body language, and consolability. Score 0–10.
- FLACC (Face, Legs, Activity, Cry, Consolability) — commonly used in paediatric settings. Score 0–10.
