Abstract
STUDY DESIGN: Prospective multicentre cohort study. OBJECTIVES: To determine mortality, causes and determinants of death of individuals with spinal cord injury (SCI) within five years after first inpatient rehabilitation. SETTING: The Netherlands. METHODS: Patients were included on admission to first clinical rehabilitation after traumatic or nontraumatic SCI. INCLUSION CRITERIA: age between 18 and 65, American Spinal Injury Association impairment scale A-D and expected long-term wheelchair dependency. Information about survival, cause of death, relevant comorbidity and psychosocial circumstances was obtained from the rehabilitation physician or general practitioner. Determinants of death were retrieved from a prospectively collected database. Deceased persons and survivors were compared using χ(2)-test and t-test. Cox regression analysis was performed to describe independent predictors of death. The Kaplan-Meier method was used to calculate survival curves for independent predictors. Excess mortality was described by a standardized mortality ratio (SMR). RESULTS: Mean duration of follow up was 6.2 years. A total of 27 persons (12.2%) died during this period (SMR 5.3). Main causes of death were cardiovascular disease (37.0%), pulmonary disease (29.6%) and neoplasm (14.8%). Older age at injury, nontraumatic SCI, family history of cardiovascular disease, less social support and a history of other medical conditions on admission were related to death. Older age at injury, nontraumatic SCI and a history of other medical conditions were independent predictors of death. CONCLUSION: Twelve per cent of persons with SCI who had survived the acute hospital phase died during follow up (SMR 5.3). The main causes of death were cardiovascular and pulmonary disease.
