Risk factors for ground-level falls differ by sex

Area of Science:

• Gerontology
• Trauma Surgery
• Public Health

Background:

• Aging populations in developed countries lead to increased elderly-related injuries.
• Ground-level falls, often considered minor, pose a significant mortality risk for older adults.
• This study addresses the underappreciated danger of falls in the elderly population.

Purpose of the Study:

• To analyze in-hospital mortality in adult patients following ground-level falls.
• To investigate the influence of age, sex, Injury Severity Score, and Revised Trauma Score (RTS) on mortality.
• To examine sex-specific effects of age and injury severity on mortality in elderly fall patients.

Main Methods:

• Analysis of 15,662 adult patients from the Japan Trauma Data Bank (2007-2013).
• Logistic regression models to assess predictors of in-hospital mortality.
• Subgroup analysis by age and sex for patients 60 years and older, considering severe injuries (Abbreviated Injury Scale >= 3).

Main Results:

• Significant interactions between sex and age, and sex and RTS, were found for in-hospital mortality.
• Older men (80+) had a 5.44 times higher mortality risk compared to younger elderly patients.
• Older women (80+) had a 2.32 times higher mortality risk, while younger elderly women (60-79) showed no significant increase.
• Lower RTS values indicated higher mortality risk, with a more pronounced effect in women (9.97) than men (6.89).

Conclusions:

• The impact of age and Revised Trauma Score on mortality after ground-level falls is sex-dependent.
• Mortality risk stratification for elderly fall patients requires consideration of sex-specific factors.
• Findings highlight the need for sex-tailored trauma care strategies for elderly fall victims.
