Summary
Survival for spinal cord-injured individuals has significantly improved since 1955. Excluding suicides, longevity increased substantially, with cardiovascular, respiratory, and urinary issues being leading causes of death.
Area of Science:
- Medical research
- Epidemiology
- Rehabilitation medicine
Background:
- Historical survival data for spinal cord injury (SCI) patients from 1955 indicated a mean survival of 52.8 months.
- Advances in medical care and management of SCI may have impacted patient longevity over time.
Purpose of the Study:
- To evaluate the changes in mean survival duration for individuals with spinal cord injuries.
- To compare current survival data with historical benchmarks.
- To identify the primary causes of mortality in this patient cohort.
Main Methods:
- Retrospective analysis of mortality data for spinal cord-injured individuals.
- Comparison of survival statistics between different time periods (1963-1976 vs. 1955).
- Categorization of leading causes of death.
Main Results:
- Mean survival for SCI patients who died between 1963-1976 was 110.5 months (9 years, 2.5 months).
- This represents a significant improvement compared to the 1955 figure of 52.8 months (4 years, 4.8 months).
- Excluding suicides, mean longevity increased to 126 months (10 years, 6 months).
- Leading causes of death included cardiovascular, respiratory, urinary tract diseases, and suicide.
Conclusions:
- There has been a marked increase in the mean survival of spinal cord-injured individuals.
- Cardiovascular, respiratory, and urinary system diseases remain significant causes of mortality.
- Suicide is a notable factor influencing overall longevity in this population.
