Fall Risk Factors and Prevention

Patient Risk Factors

The American Geriatrics Society guidelines state that a patient's fall history represents the highest risk factor for future falls during hospitalization, with a relative risk of 3.0 (range 1.7-7.0) 1
Fall history is consistently identified as one of the strongest independent predictors of future falls across all clinical settings, according to the American Geriatrics Society 1
The patient's mental status is intact, as she is "alert and oriented to person, place, time, and event" with normal neurologic examination, which does not contribute to her current risk profile, as noted by the American College of Emergency Physicians 2
Far-sightedness requiring reading glasses does not constitute the type of visual deficit that significantly increases fall risk, as stated by the American Geriatrics Society 1
The patient's physical therapy evaluation states she is "independent to chair and bathroom," indicating preserved functional mobility, according to the American College of Emergency Physicians 2

The patient's fall pattern and recent hydrochlorothiazide initiation suggest orthostatic hypotension as the mechanism, as reported by the American College of Emergency Physicians 2, 3
Diuretics carry an odds ratio of 1.1 for falls in meta-analysis, and orthostatic blood pressure assessment should be performed on all patients presenting after falls, according to the American Geriatrics Society and the American College of Emergency Physicians 1, 2
The dry mucous membranes noted on examination suggest volume depletion from the diuretic, as observed by the American College of Emergency Physicians 2

All patients admitted to the hospital after a fall require evaluation by physical therapy and occupational therapy per guidelines from the American College of Emergency Physicians 2, 3
Medication review with particular attention to the recently initiated hydrochlorothiazide is essential, as reduction of medications was a prominent component of effective fall-reducing interventions, according to the American Geriatrics Society 4
Orthostatic vital signs must be assessed, as management of postural hypotension was part of effective interventions in multiple studies, as stated by the American Geriatrics Society 4
The combination of fall history plus medication-induced orthostasis creates compounding risk, with patients taking four or more medications having progressively higher fall prevalence, according to the American Geriatrics Society 1

The American Geriatrics Society, British Geriatrics Society, and American Academy of Orthopaedic Surgeons explicitly state that falling is associated with considerable mortality, morbidity, reduced functioning, and premature nursing home admissions, with falls being the leading cause of injury-related death among adults aged 65 and older 5.
In the USA, falls are the leading cause of injury-related death among persons aged 65 and over 6.

A history of falls is itself one of the strongest risk factors for future falls, with a relative risk of 3.0 (range 1.7-7.0), among elderly persons who have suffered a fall episode 7, 8.

The combination of high fall incidence and high susceptibility to injury creates the mortality risk, not simply the falls themselves, due to high prevalence of comorbid diseases and age-related physiological decline 5, 9, 10.
Approximately 5% of older people who fall require hospitalization, with 10% to 25% of institutional falls resulting in fracture, laceration, or need for hospital care 5, 9, 7, 8.

Two or more falls in the past year signal a patient at substantially elevated risk who requires immediate multifactorial intervention 6.

Multifactorial interventions can reduce fall rates by 23% (Rate Ratio 0.77, 95% CI 0.67-0.87), directly impacting mortality risk 6.
Comprehensive multifactorial risk assessment addressing modifiable factors, including medication review and deprescribing when appropriate, can reduce fall risk 5, 11.

Do not dismiss multiple falls as "normal aging"—this represents a medical emergency requiring comprehensive evaluation, as older people are frequently not aware of their fall risks and do not report these issues to physicians 5.
