Ground-Level Falls as a Leading Cause of Major Trauma in Older People

BACKGROUND
Major trauma is conventionally associated with high-energy mechanisms such as road traffic collisions or falls from height. However, ground-level falls (GLFs) , defined as unintentional descents to the ground from standing height or below , are an increasingly recognised cause of serious injury and death in older adults.[1,2] Despite appearing to involve low-energy forces, GLFs frequently result in devastating injuries in elderly patients, driven by age-related physiological changes including osteoporosis, frailty, and anticoagulant use.[3,5]
With the UK's older population growing rapidly, and GLFs already representing a significant proportion of trauma centre admissions, understanding injury patterns, outcomes, and risk factors is critical for both preventive strategy and trauma service organisation.

METHODS
A literature review was conducted using PubMed, MEDLINE, and Google Scholar. Search terms included 'ground-level falls', 'low falls', 'geriatric trauma', 'older adult injury', 'frailty and trauma', and 'fall prevention'. UK and international studies from the past 10–15 years were reviewed, focusing on injury patterns, clinical outcomes, triage considerations, and evidence-based prevention strategies.

RESULTS
GLFs account for a large and increasing proportion of major trauma in older adults. A national US trauma database analysis of over one million geriatric patients (2011–2015) found that 39% had sustained a fall as the mechanism of injury, with incidence rising proportionally with age.[6] Comparable trends are observed in UK trauma registries.
Common serious injuries resulting from GLFs include:
Traumatic brain injury (TBI) and intracranial haemorrhage - thoracic injuries and intracranial haemorrhage were independently associated with ICU admission in one cohort study of GLF patients aged 65 and over.[7]
Cervical spine fractures , often occurring at low energy in the presence of osteoporosis or pre-existing spinal degeneration.[3]
Hip fractures and rib fractures , particularly in those on anticoagulant therapy, in whom haemorrhagic complications are compounded.[8]
Age-related factors that amplify injury severity include: reduced bone mineral density (osteoporosis affects over 3 million people in the UK); impaired protective reflexes; anticoagulant use; pre-existing cognitive impairment; and the presence of frailty, which is recognised as a stronger predictor of 12-month mortality than injury severity score alone.[4,5]
Clinical outcomes in older GLF patients are consistently worse than in younger trauma patients, with higher in-hospital mortality, longer hospital stays, and greater rates of discharge to residential or nursing care.[6] A key concern is under-triage: because the mechanism appears low-energy, GLF patients are often not fast-tracked into major trauma protocols, despite sustaining injuries of comparable severity.[2,8] Vital signs may also appear falsely reassuring in older adults, masking physiological deterioration.
Prevention evidence supports: comprehensive multidisciplinary falls assessments; structured medication reviews with deprescribing of high-risk agents; strength and balance training programmes (e.g. the OTAGO programme); home hazard modification; and the management of osteoporosis and visual impairment.[4,9]

CONCLUSION 
Ground-level falls are a major and growing cause of serious trauma in older adults, challenging traditional assumptions about injury mechanism and severity. The interaction of frailty, comorbidity, and osteoporosis means that even a simple trip from standing height can result in life-threatening injury. Trauma triage systems must be adapted to reflect the disproportionate risk carried by older patients following GLFs. Simultaneously, investment in evidence-based falls prevention , delivered across primary, secondary, and community care , is essential to reduce the burden of this underappreciated cause of major trauma.
