Hip fractures in older adults often lead to long-term disability and significantly increased mortality. The majority of hip fractures are the result of a fall in the elderly population. About 20–30% of older adults (≥65 years old) experience one or more falls each year, and falls are associated with a substantial burden to the health care system, individuals, and families due to resulting injuries, fractures, and reductions in functioning and quality of life.
The integration of mortality risk prediction into fall prevention strategies can enhance early identification of high-risk individuals and enable targeted interventions. This paper discusses a framework that incorporates a validated 1-year mortality prediction model, originally developed for post-hip fracture surgical patients, into proactive fall prevention strategies for community-dwelling seniors.
Introduction: Falls are the leading cause of injury-related morbidity and mortality in older adults. Hip fractures, in particular, are associated with a 1-year mortality rate of approximately 20%. Traditional fall prevention programs focus on reducing fall incidence, yet often overlook the consequences of falls in frail individuals. A recent study by Alexiou et al. developed a 1-year mortality prediction model based on seven preoperative variables, offering an opportunity to integrate mortality risk stratification into fall prevention.
Methods: Following risk factors are identified in Alexiou et al.'s model, which include age >80, ASA score ≥3, Charlson Comorbidity Index >6, BMI <25 kg/m2, male sex, use of anticoagulants, and delayed surgery (>48 hours). We propose using these variables as proxies for frailty and fall consequence severity in non-surgical older adult populations. The integration strategy also includes evidence from meta-regressions showing that strength gains can be achieved without training to failure, supporting the safe inclusion of resistance training in frail populations.
Results: We present a stratified intervention approach:
Low Risk (Score 0–4): General lifestyle and balance-focused interventions.
Moderate Risk (Score 5–7): Structured exercise with progressive resistance and home safety assessments.
High Risk (Score 8–10): Multidisciplinary interventions including physical therapy, medication review, and nutritional support.
Very High Risk (Score 11–13): Intensive fall-proofing, caregiver support, and possible palliative planning.
To illustrate, consider an 86-year-old male patient with a Charlson Comorbidity Index (CCI) >6, ASA score of 3, and a surgical delay of more than 48 hours. According to the model, this individual would have a mortality score of 10, corresponding to an estimated 29% to 31% risk of death within one year. Identifying such high-risk individuals preemptively can inform the intensity and scope of fall prevention strategies tailored to their specific needs. The dose-response evidence on training proximity to failure further reinforces how exercise regimens can be customized to balance effectiveness and safety, especially in frail older adults.
Discussion: This integrated model allows clinicians and community programs to prioritize resources effectively. Screening for mortality risk factors as part of routine geriatric assessment can preempt severe outcomes by tailoring fall prevention efforts to those most at risk of serious injury or death. Additionally, the strategy respects patient preferences by avoiding overexertion and promoting safety.
Conclusion: Integrating a hip fracture mortality prediction model into fall prevention strategies represents a novel, risk-informed approach to reduce both the incidence and severity of falls. This framework empowers clinicians to deliver targeted, safe, and effective interventions, potentially improving outcomes for older adults.
