Mortality After Hip Fracture Beyond the First Year

Introduction to Mortality Rates

• Up to 15-30% of patients die within one year of hip fracture surgery, representing a three-fold increase compared to the general geriatric population 1, 2, 3
• The 30-day mortality stands at 8.4%, with up to half of these deaths potentially preventable 1, 3

Mortality Risk Over Time

• Mortality is highest in the immediate post-fracture period and gradually decreases but remains elevated throughout the first year 4
• The increased relative risk for mortality remains elevated for months and perhaps even years following the index fracture, though it becomes less pronounced with time 5
• Patients face a 3- to 4-fold increased risk of mortality in the 5 years following any fragility fracture 5

Risk Factors for Mortality

• Male sex is associated with significantly higher mortality (38% in men vs 24% in women at one year for hip fractures) 5, 3
• Advanced age (particularly ≥86 years) correlates with the highest mortality rates 3
• Greater comorbidity burden and frailty increase death risk 1, 3
• Sarcopenia is the strongest predictor of out-of-hospital mortality (hazard ratio 4.77) 3

Clinical Implications

• The American College of Radiology suggests that patients face a 3- to 4-fold increased risk of mortality in the 5 years following any fragility fracture 5
• Early surgical intervention (within 24-48 hours) is recommended to optimize outcomes 3
• Secondary fracture prevention is crucial, as subsequent fragility fractures carry particularly poor prognosis 1, 2
