- W4387249600 abstract "SESSION TITLE: Chest Infections Posters 1 SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/10/2023 12:00 pm - 12:45 pm PURPOSE: The novel coronavirus SARS-CoV-2, better known as COVID-19, has been shown to have major thromboembolic complications. Data supports pharmacologic thromboprophylaxis for all inpatients with COVID-19. The American Society of Hematology recommends against continued thromboembolic prophylaxis upon hospital discharge. However, the recent MICHELLE trial showed a significant reduction in post-discharge thrombotic events with extended use of anticoagulation in patients deemed high risk based a scoring system (accounting for active malignancy, known thrombophilic disorder or history of prior thromboembolic disease). The purpose of our study is to help identify hospitalized patients without known predisposing conditions who are at high risk of thromboembolic complications of COVID-19 post-discharge. METHODS: This is a single-center retrospective analysis of approximately 150 adult patients hospitalized with COVID-19 between August 1st, 2021 and August 1st, 2022. Study group is defined as having thromboembolic events within 60 days of testing positive for COVID-19. Control group is defined is patients who did not have thromboembolic complications. Patients with known malignancy, thrombophilic disorder, or prior VTE were excluded. Patient data includes C-reactive protein (CRP) and D-dimer levels, degree of hypoxia and/or need for ventilatory support and basic patient characteristics such as age and gender. Analysis was based on ANOVA with a P value of less than .05 to determine significance. RESULTS: Results showed a significant difference in D-dimers between COVID-19 infected patients with VTE compared to COVID-19 infected patients without VTE (P = .00531). No significant difference was noted in CRP levels (p = .536) between the two groups. PE was the most common diagnosis of VTE among COVID-19 infected patient and those who were readmitted. Interestingly, elevated CRP was associated with readmission for VTE (p = .03) while D-dimer was not associated with VTE readmission (p = .6). CONCLUSIONS: D-dimer is a good marker to determine risk of VTE patients with active COVID-19 infection. Certain characteristics such as elevated CRP seen in COVID-19 patients with thromboembolic disease may ultimately guide prophylaxis for thromboembolic disease upon discharge. CLINICAL IMPLICATIONS: Inflammatory markers such as D-dimer and CRP may help identify those patients who are at higher risk of developing thromboembolic complications of COVID-19 and who would benefit from continued prophylactic anticoagulation upon hospital discharge.
