Deconditioning, contractures, pressure injuries, DVT, pneumonia
Hip fracture, head injury, fear of falling — major cause of functional decline
Dementia and delirium — overlapping, under-diagnosed
Urge, stress, overflow — social isolation, skin breakdown, falls to toilet
Adverse drug reactions, hospital-acquired delirium, catheter-associated UTI, falls
| Condition | Typical Presentation | Atypical Presentation in Elderly |
|---|---|---|
| Myocardial Infarction | Central crushing chest pain, diaphoresis | Confusion, falls, fatigue, epigastric pain — NO chest pain in ~40% |
| UTI / Sepsis | Dysuria, frequency, fever | Acute delirium, falls, anorexia, incontinence — may be afebrile |
| Appendicitis | RIF pain, fever, rebound tenderness | Minimal peritonism, vague abdominal discomfort, late presentation |
| Pneumonia | Cough, fever, pleuritic pain | Confusion, tachypnoea, reduced mobility, loss of appetite |
| Hypoglycaemia | Sweating, palpitations, anxiety | Confusion, focal neurology, falls — adrenergic response blunted |
Frailty is a state of increased vulnerability to stressors resulting from age-related cumulative decline across multiple physiological systems, exceeding the body's capacity to maintain homeostasis. It is distinct from comorbidity and disability but frequently co-exists.
3 or more of 5 criteria = FRAIL | 1–2 = Pre-frail | 0 = Robust
| # | Criterion | Threshold |
|---|---|---|
| 1 | Unintentional weight loss | >4.5 kg in past year |
| 2 | Exhaustion / low energy | Self-reported most days |
| 3 | Low physical activity | Below sex-specific threshold (kcal/week) |
| 4 | Slow gait speed | Slowest quintile adjusted for height/sex |
| 5 | Weak grip strength | Lowest quintile adjusted for BMI/sex |
| Domain | Tools / Content |
|---|---|
| Medical | Comorbidities, medication review, nutrition (MNA), continence |
| Functional | ADLs: Barthel Index / Katz Index; IADLs: Lawton Scale |
| Cognitive / Psychological | MMSE, MoCA (≤25 = mild impairment); GDS-15 for depression |
| Social / Environmental | Living situation, carer support, financial, home hazards |
10 domains scored 0–2 each. Maximum 17 points. Easily performed by nurses.
Delirium is an acute neuropsychiatric syndrome characterised by a disturbance of consciousness and cognition that develops over hours to days, with a fluctuating course.
Can be completed in <2 minutes by nurses at the bedside
| Item | Max Score |
|---|---|
| Alertness — observe level of arousal | 4 |
| AMT4 — age/DOB/place/year (1 error = 1 pt) | 2 |
| Attention — months of year backwards | 2 |
| Acute change or fluctuation | 4 |
Delirium = Features 1 AND 2, PLUS Feature 3 OR 4
PINCH ME — Precipitating Factors
Score ≥2 = high risk
Polypharmacy is defined as the concurrent use of 5 or more regular medications. It is extremely common: approximately 75% of adults over 65 in GCC countries take 5 or more medications.
Screening Tool of Older Persons' Prescriptions (O'Mahony et al.)
| Drug Class | Reason to Stop in Elderly |
|---|---|
| Benzodiazepines | Fall risk, sedation, cognitive impairment, dependence |
| Tricyclic antidepressants (TCAs) | Anticholinergic effects, fall risk, cardiac arrhythmias |
| Antipsychotics | Fall risk, stroke risk in dementia, QT prolongation |
| NSAIDs (any route) | GI bleed, renal failure, CV events, fluid retention |
| Sulfonylureas (long-acting) | Hypoglycaemia risk (especially with renal impairment) |
| Proton pump inhibitors at full dose | Long-term use without indication — step down dose |
| Anticholinergic drugs | Cognitive impairment, urinary retention, constipation, falls |
Screening Tool to Alert to Right Treatment
| Drug / Indication | If Absent — Consider Adding |
|---|---|
| ACE-I or ARB | Heart failure with reduced ejection fraction; DM + CKD |
| Anticoagulation (DOAC) | AF with CHA₂DS₂-VASc score ≥2 (males) / ≥3 (females) |
| Statin therapy | Established CVD (secondary prevention) |
| Bisphosphonate + Vitamin D | Long-term corticosteroid therapy >3 months |
| Vitamin D supplementation | Care home resident or housebound elderly |
| Beta-blocker | Stable systolic heart failure |
| Antiplatelet (aspirin/clopidogrel) | Established coronary, peripheral, or cerebrovascular disease |
| Feature | Delirium | Dementia | Depression |
|---|---|---|---|
| Onset | Sudden (hours–days) | Insidious (months–years) | Gradual (weeks–months) |
| Course | Fluctuating (worse at night) | Progressive, slow decline | Persistent, consistent low mood |
| Consciousness | Clouded, altered | Normal until late stages | Normal |
| Attention | Severely impaired | Normal until late | Usually intact |
| Memory | Short-term impaired | Short and long-term impaired | Variable (pseudodementia) |
| Mood | Fearful, agitated, or apathetic (variable) | Flat, irritable, disinhibited | Persistently low, tearful, worthless |
| Sleep-wake | Severely disrupted, reversed | Disrupted in later stages | Early morning waking, hypersomnia |
| Reversible? | Usually yes (treat cause) | No (some dementias slow with treatment) | Yes with treatment |
| Assessment tool | 4AT, CAM | MMSE, MoCA, ACE-III | GDS-15, PHQ-9 |
