Purpose: To compare the specificity and sensitivity of preoperative D-dimer and age-adjusted D-dimer value for predicting the incidence of the DVT preoperatively in total joint arthroplasty (TJA) patients.
Methods: We enrolled 406 patients finally above 50 years old. Everyone had done ultrasonography bedside, and D-dimer concentrations were collected before surgery. The D-dimer and age-adjusted D-dimer cut-off was calculated by multiple logistic regression and receiver operating curve (ROC) analyses.
Results: A total of 39 patients had found asymptomatic deep vein thrombosis (DVT) by ultrasonography. The age (odds ratio [OR] 1.067; p = 0.003) and D-dimer (OR 1.331; p = 0.025) were related to the existence of DVT. For conventional D-dimer and age-adjusted D-dimer value, the area under the curves (AUCs) were 0.685 (0.499-0.696) and 0.795 (0.611-0.881), respectively.
Conclusion: Compared to traditional D-dimer, age-adjusted D-dimer showed better performance in screening DVT, which was useful clinically.

Background: Pulmonary thromboembolism (PTE) is a preventable yet potentially fatal condition with significant morbidity and mortality. Several clinical scoring systems, including the Wells and modified Geneva scores, have been developed to assess the likelihood of PTE and guide further diagnostic evaluation. The Padua prediction score, primarily used to assess venous thromboembolism (VTE) risk in hospitalized patients, has also been considered for its potential utility in suspected PTE cases.

Background: The current deep vein thrombosis (DVT) diagnostic algorithms are rarely followed in clinical practice due to complexity and time constraints. Simplified alternatives are needed to enhance adherence while maintaining diagnostic accuracy. The ToDay algorithm was developed to address these concerns by combining physician implicit assessment of DVT likelihood with D-dimer testing.

Background: The patients with suspected pulmonary embolism (PE) were usually screened using electrocardiogram (ECG) and blood panel of D-dimer, troponin, and blood gas analysis in the emergency.
Objectives: This study aimed to explore a rapid risk model to predict in-hospital adverse events for normotensive PE patients.
Methods: Patients with acute PE having normal blood pressure on appearance were retrospectively enrolled at China-Japan Friendship Hospital from January 2017 to February 2020.

Background: Studies on pulmonary embolism (PE) rule-out strategies traditionally recruited patients in the ED. This method is increasingly impractical given excessive pressures experienced in EDs. Attempting to reach patients after leaving the ED may be more feasible.

Introduction: Studies have suggested that an age-adjusted D-dimer (AADD) could improve specificity while maintaining sensitivity for the diagnosis of pulmonary embolism (PE). Most laboratories and published data report D-dimer in fibrinogen equivalent units, but some laboratory assays report using D-dimer units (DDU). However, only two small studies have examined AADD with a DDU-based assay.
