We’d really appreciate if you could leave us a rating ⭐️❤️


Those over 65 have the highest risk of falling with 30% of those over 65 and 50% of those over 80 falling at least once a year. ¹ Falls can have a profoundly negative impact on the quality of life of the elderly and their carers. The physical distress, pain and injury are also associated with loss of confidence and independence. This negatively affects morbidity and mortality with associated financial implications for the NHS.

History of presenting complaint

A detailed history is essential in determining the cause of falls. The table below highlights key information that should be gathered when taking a history.

WHO:Who has seen you fall?Ensure adequate collateral history including addressing the when, where, what and why.
WHEN:When did you fall?What time of day?

What were they doing at the time:

  • Looking upwards (vertebrobasilar insufficiency)
  • Getting up from bed (postural hypotension)
WHERE:Where did you fall?In the house, or outside?
WHAT:What happened before/during and after the fall?Before:

  • Is there any warning?
  • Is there any dizziness/chest pain or palpitations?



  • Is there any incontinence or tongue biting (indicating seizure activity).
  • Was there any loss of consciousness?
  • Is the patient pale/flushed (may indicate vasovagal attack)?
  • Did they injure themselves?
  • What part of the body had the first contact with the floor?


  • What happens after the fall?
  • Is the patient able to get themselves up?
  • How long does it take them?
  • Are they able to resume normal activities afterwards?
  • Was there any confusion after the event? (head injury)
  • Was there any weakness or speech difficulty after the event? (stroke/TIA)
WHY:Why do you think you fell?May have tripped over a rug or started a new medication.
HOW:How many times have you fallen over the last 6 months?Allows you to gauge the severity of the problem.

Be cautious in cases where the patient is unable to recall events clearly, as this may indicate new confusion associated with a head injury.

Systems Enquiry

A systems enquiry may identify other relevant information that may relate to the falls.

  • Fatigue
  • Weight loss
  • Chest pain
  • Palpitations
  • Shortness of breath
  • Cough
  • Loss of consciousness
  • Seizures
  • Motor or sensory disturbance
  • Incontinence
  • Urgency
  • Dysuria
  • Abdominal pain
  • Diarrhoea
  • Constipation
  • Joint pain
  • Muscle weakness

Past Medical History

  • Visual/hearing impairment
  • Diabetes
  • Anaemia
  • Cardiovascular disease
  • Arrhythmias
  • COPD
  • Parkinson’s disease
  • Peripheral neuropathy
  • Stroke
  • Dementia
  • Recurrent urinary tract infection
  • Incontinence
  • Diverticulitis
  • Chronic diarrhoea
  • Alcoholic liver disease
  • Arthritis
  • Chronic pain
  • Fractures

Social History

  • Alcohol intake
  • Support at home – friends/family and carers
  • Mobility – use of aids and when (e.g. zimmer frame downstairs only)

Medication review

Most medications have side effects which could cause falls. Polypharmacy itself is a risk factor for falls. It is good practice to review medications and de-prescribe those which are no-longer indicated.

  • Beta-blockers (bradycardia)
  • Diabetic medications (hypoglycaemia)
  • Antihypertensives (hypotension)
  • Benzodiazepines (sedation)
  • Antibiotics (intercurrent infection)



  • Is the patient alert and orientated?
  • Are they able to perform the timed “up and go” test?
  • Pulse: may have irregularities such as AF or bradycardia
  • Blood pressure – hypotension
  • Bruits over carotid arteries
  • Murmurs: aortic stenosis/regurgitation, mitral stenosis
  • Inspection: increased work of breathing
  • Auscultation: coarse crackles (e.g. pneumonia)
  • Percussion: dullness (e.g. pleural effusion)
  • Cranial nerve examination: stroke or visual impairment
  • Power: weakness (e.g. stroke, disuse atrophy)
  • Tone: increased in stroke
  • Reflexes: absent (e.g. diabetic neuropathy), hyperreflexia (e.g. upper motor neuron pathology)
  • Sensation: may be reduced secondary to upper or lower motor neuron pathology
  • Co-ordination: may be impaired (e.g. chronic alcohol misuse leading to cerebellar degeneration)
  • Abdominal tenderness
  • Organomegaly
  • Check for injuries associated with falls and examine carefully the point of contact with the floor
  • Is there any evidence of ear wax?
  • Are the tympanic membranes intact?

Timed up and go test:

  • Ask the patient to get up from the chair/bed and walk three metres then turn around and sit down again. The patient should be permitted to use their walking aid.


Investigations are based on your history and examination but could include some of those mentioned below.

BedsideObservations (BP/HR/RR/Sats/Temp)
  • Sepsis
  • Bradycardia
Lying and standing blood pressure
  • Orthostatic hypotension
Urine dipstick
  • Infection
  • Rhabdomyolysis (blood in urine)
  • Bradycardia
  • Arrhythmias
Cognitive screening e.g. AMT
  • Cognitive impairment
Blood glucose
  • Hypoglycaemia secondary to poor oral intake
BloodsFull Blood Count
  • Anaemia
  • Infection
Urea and Electrolytes
  • Dehydration
  • Electrolyte abnormalities
  • Rhabdomyolysis

  • Chronic alcohol use
Bone profile
  • Calcium abnormalities in malignancy or over supplementation
ImagingChest X-ray
  • Pneumonia
CT head
  • Chronic or acute subdural
  • Stroke
  • Valvular heart disease e.g aortic stenosis
SpecialistTilt table test
Epley manoeuvre
  • Benign paroxysmal positional vertigo
Cardiac monitoring (e.g. 48hr tape)
  • If no symptoms during monitoring episode in hospital

Differential diagnosis

The differential diagnosis of falls is very wide. A detailed history and examination will lead to the eventual diagnosis. It is important to determine whether the patient has suffered a transient loss of consciousness or a simple mechanical fall.

Some possible causes of falls are shown in the table below.

  • Mechanical (always give a reason e.g. secondary to poor footwear/visual difficulties)
  • Polypharmacy
  • Arrhythmias
  • Orthostatic hypotension
  • Bradycardia
  • Valvular heart disease
  • Stroke
  • Peripheral neuropathy
  • Incontinence
  • Urinary tract infection
  • Hypoglycaemia
  • Arthritis
  • Disuse atrophy
  • Benign paroxysmal positional vertigo
  • Ear wax


Once a transient loss of consciousness event has been ruled out, it is important to complete a full falls risk assessment. This is indicated in order to identify any causative features especially as older people are likely to have multiple co-existing factors causing a fall. Although priority should be to treat any underlying medical cause (e.g. pacemaker if complete heart block), all causes should be addressed where possible.  Due to the complex aetiology, it is important to continue to search for possible risk factors and causes of falls even when one has been found.

The table below includes some of the key components of a full falls risk assessment.

  • Physiotherapy
2Visual problems
  • Eye test and ensure wears glasses
3Hearing difficulties
  • Remove earwax
  • Hearing assessment
4Medications review
  • Reduce unnecessary meds
5Alcohol intake
  • Alcohol cessation advice
  • Alcohol service referral
6Cognitive impairment
  • Referral to a psychiatric team
7Postural hypotension
  • Review medication
  • Improve hydration
  • Treat or rule out infections
  • Continence assessment
  • Ensure good fitting footwear
10Environmental hazards
  • Turn on lights
  • Take up rugs
