Abstract Objective: To observe the value of Wells score in diagnosis of deep vein thrombosis after spinal cord injury. Methods: 196 patients admitted in our rehabilitation department between May 2014 to December 2015 were obversed. Lower extremity deep venous ultrasonography was carried to diagnosis deep vein thrombosis, and the Wells score was used to evaluate all patients. Results: The Wells score in evaluation of deep venous thrombosis of spinal cord injury patients in rehabilitation stage sensitivity was 64.3%, misdiagnosis rate was 35.7%, and the specificity was 99.3%, and the misdiagnosis rate was 0.7%, the Youden's index was 63.6%, the positive predictive value was 97.3%, the negative predictive value was 87.4%, the positive likelihood ratio is 91.9, negative likelihood ratio was 0.36. Conclusions: There is a higher Wells score of false negative diagnosis of deep venous thrombosis in patients with spinal cord injury. Wells score is not an effective method to evaluating deep venous thrombosis.
