Long-term outcomes after injury in the elderly

Area of Science:

• Geriatric Trauma
• Quality of Life Research
• Public Health

Background:

• The long-term effects of traumatic injuries on the lifestyle and well-being of elderly individuals are not well understood.
• Previous research has not adequately defined the persistent impact of injury on daily living in older populations.

Purpose of the Study:

• To assess the long-term quality-of-life outcomes in elderly patients who have experienced traumatic injuries.
• To quantify the residual disability and lifestyle changes in older trauma survivors.

Main Methods:

• Utilized a trauma registry to identify elderly (>=65 years) survivors discharged between April 1996 and March 1999.
• Administered the 36-Item Short Form (SF-36) Health Survey via telephone interview and compared scores to age-adjusted Canadian norms.
• Analyzed data using appropriate statistical tests for continuous variables.

Main Results:

• A significant decrease (p < 0.05) in seven of eight SF-36 domains was observed compared to age-adjusted norms, including Physical Functioning, Role-Physical, Role-Emotional, Social Functioning, Mental Health, Vitality, and General Health.
• While 98% of patients lived independently before injury, only 63% maintained independent living at a mean follow-up of 2.8 years; 20% required ongoing home care.
• The study included 128 elderly trauma survivors (75% data collection rate) with a mean age of 74 and a mean Injury Severity Score of 21.

Conclusions:

• Elderly trauma survivors demonstrate significant residual disability impacting their quality of life, even when they achieve independent living.
• Long-term follow-up using the SF-36 highlights persistent functional and social limitations in this demographic post-injury.
