A method to increase the usefulness of D-dimer in the diagnosis of VTE is warranted. This study aimed to investigate the usefulness of the combination of D-dimer and soluble fibrin monomer complex (SFMC), which has been suggested as a new candidate marker for VTE, in VTE diagnosis.Patients and Methods: This prospective study in 109 subjects was performed at a psychiatric department between August 1, 2017 and December 31, 2019. Subjects’ levels of D-dimer and SFMC were measured simultaneously. Plasma levels of D-dimer and SFMC were measured using NANOPIA® D-dimer and NANOPIA® SF. Subjects with positive D-dimer (≥ 1.0 μg/mL) results underwent contrast computed tomography for confirmation of VTE within 12 hours of D-dimer measurement. A receiver operating characteristic curve analysis was performed to examine the usefulness of SFMC for the diagnosis of VTE.Results: Only 109 of the 783 subjects without symptoms suggestive of VTE participated in the study. Out of 41 subjects with positive D-dimer results, 17 subjects were diagnosed with VTE. A receiver operating characteristic curve analysis was performed to determine cutoff values. The area under the curves was 0.848 for SFMC (p< 0.001, 95% CI 0.722 to 0.974), and the optimal cutoff value was 10.0 μg/mL (sensitivity 58.8%, specificity 100%, positive predictive value 100%, negative predictive value 77.4%).Conclusion: SFMC was useful for diagnosing VTE in the psychiatric patients with positive D-dimer results.Keywords: computed tomography, D-dimer, psychiatric patients, soluble fibrin monomer complex, venous thromboembolism
