Falls and Frailty in the Elderly
On this page
Direct answer
Falls in older adults are unintentional descents to the ground or a lower level, and frailty is the reduced physiological reserve that makes a fall more likely and recovery slower. Falls are best understood as a multifactorial geriatric syndrome, so prevention depends on structured assessment of gait, medicines, vision, cognition and orthostatic blood pressure. Exercise, deprescribing and treatment of bone fragility together reduce risk more than any single measure.
What you must remember
- Fall definition: An unintentional coming to rest on the ground or a lower level; a long lie is a fall after which the person cannot rise unaided for a prolonged period.
- Fried phenotype: Unintentional weight loss, exhaustion, weak grip, slow walking speed and low physical activity; three or more features define frailty, one or two define pre-frailty.
- Timed Up and Go: Taking longer than about 12 seconds suggests raised fall risk and warrants full assessment.
- Orthostatic hypotension: A fall of at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of standing, often with symptoms.
- Polypharmacy: Five or more regular medicines raise risk; sedatives, antipsychotics, antidepressants, opioids, antihypertensives and insulin or sulphonylureas are high-risk drugs.
- Best single intervention: Exercise combining strength, balance and gait training reduces falls in community-dwelling older adults.
- Low-energy hip fracture: It should prompt osteoporosis treatment as secondary prevention, not be treated as an isolated injury.
A night-time fall and a structured assessment
A 79-year-old woman falls while walking to the toilet at night and lies on the bedroom floor for nearly two hours before her daughter finds her. She has right hip pain and cannot bear weight.
- Image the hip: Confirm the injury with a hip radiograph, keeping a low threshold for CT or MRI if films are normal and she still cannot walk.
- Check for rhabdomyolysis: Check creatine kinase and renal function, since a long lie raises the risk of rhabdomyolysis.
- Ask why she fell: The question is why she fell, not just that she fell. Lying and standing blood pressure, with a reading at three minutes of standing, looks for orthostatic hypotension.
- Check the heart: The ECG checks for arrhythmia or conduction disease, because a blackout can look like a trip.
- Review the medicines: She takes amitriptyline, zolpidem, amlodipine and furosemide. Amitriptyline is sedating and anticholinergic, zolpidem adds further sedation, and furosemide explains the nocturia that took her to the toilet.
- Assess the environment: Cognition, vision, footwear and night lighting are assessed, and the home is checked for hazards.
- Treat the bone: Because her hip fracture followed a low-energy fall, osteoporosis treatment starts alongside vitamin D correction, and physiotherapy begins early.
Where falls questions go wrong
Falls questions turn on a few predictable errors.
- Trap: attributing the fall to ageing and stopping there. Correct: the examiner expects a cause even when several factors contribute.
- Trap: confusing syncope with a mechanical fall. Correct: a patient who blacks out and falls needs cardiac evaluation, whereas a trip over a rug does not.
- Trap: withdrawing one sedative while adding another. Correct: the exam rewards structured deprescribing over blanket withdrawal, because polypharmacy is not always wrong.
- Trap: taking one blood pressure straight after standing. Correct: the lying-to-standing protocol has defined timings, since an early reading can miss delayed orthostatic hypotension.
Indian examinations also expect awareness of the National Programme for Health Care of the Elderly, whose district geriatric clinics provide the structured assessment that falls prevention needs.
Frequently asked questions
What are the Fried criteria for frailty?
Fried criteria define frailty through five features: unintentional weight loss, self-reported exhaustion, low grip strength, slow walking speed and low physical activity. Meeting three or more features indicates frailty, while one or two suggest pre-frailty, making it a practical screening tool.
What is orthostatic hypotension in older adults?
Orthostatic hypotension is a fall of at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of standing, often with dizziness. In older adults it is a common and modifiable cause of falls, with antihypertensives, diuretics and alpha blockers among the frequent contributors.
Which drugs most increase fall risk in older people?
Sedative-hypnotics, benzodiazepines, antipsychotics, opioids, antidepressants and antihypertensives raise fall risk through sedation, dizziness and postural hypotension. A structured medication review using explicit criteria such as STOPP and START helps identify candidates for withdrawal.
Which intervention reduces falls most reliably in community-dwelling older adults?
Exercise programmes combining strength, balance and gait training reduce falls more reliably than any single intervention in community-dwelling older adults. They work best alongside medication review, vision correction and home hazard reduction.
How should a low-energy hip fracture be followed up?
A low-energy hip fracture should prompt osteoporosis treatment as secondary fracture prevention, usually with an antiresorptive agent alongside calcium and vitamin D. Correction of vitamin D deficiency and early mobilisation are also part of comprehensive care after hip fracture.
