Risk of stroke, heart attack, and diabetes complications among veterans with spinal cord injury.

摘要

OBJECTIVES: To compare the rates of diabetes and macrovascular conditions in veterans with spinal cord injury (SCI) and to examine variations by patient-level demographic, socioeconomic, access, and health status factors. DESIGN: A retrospective analysis. Diabetes status was classified by merging with diabetes epidemiology cohort using a validated algorithm. Chi-square tests and logistic regressions used to compare rates in macro- and microvascular conditions in veterans with and without diabetes. SETTING: Veteran Health Administration clinic users in fiscal year (FY) 1999 to FY 2001. PARTICIPANTS: SCI patients (N=8769) with diabetes (n=1333), in FY 2000, identified through the SCI registry. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Macrovascular and microvascular conditions in the next year (February 2001). Derived from International Statistical Classification of Diseases, 9th Revision, Clinical Modification, codes in the patient treatment files. RESULTS: Overall, 15% of SCI veterans were identified with diabetes but this was an underestimate due to high mortality (8%). Among SCI veterans with diabetes, 49% had at least one macrovascular condition and 54% had microvascular conditions compared with 24% and 25% of those without diabetes (P<.001). CONCLUSIONS: Our study highlights the highly significant relationship between diabetes and macro- and microvascular conditions in veterans with SCI. Neurologic deficit combined with increased insulin resistance has a greater macrovascular impact on SCI veterans than on those who do not have diabetes. Increasing age and physical comorbidities compound the problem.
