Association of age-adjusted D-dimer with deep vein thrombosis risk in patients with spinal cord injury: a cross-sectional study.

Study design Article. Objective To elucidate the association of age-adjusted D-dimer (AAD) with deep vein thrombosis (DVT) risk to lower limbs in patients with spinal cord injury (SCI). Setting Rehabilitation Medicine Department of the First Affiliated Hospital of China University of Science and Technology. Methods Retrospective analysis of 250 patients with SCI in the rehabilitation department from August 2018 to December 2021. Quartiles divided the D-dimer level into four groups to analyze the association between AAD level and DVT risk. Results Age was identified as a covariate of D-dimer and DVT risk. For non-adjusted model, when D-dimer increased by 1 mg/L, DVT risk increased 0.23-fold (P 1.9 mg/L (K > 1.9), the estimated change was 1.14 (P Conclusion Patients with SCI who receive rehabilitation treatment with AAD level >1.9 mg/L need to be paid close attention to, especially those with UTI and high levels of fibrinogen.
