Objective: One of the most critical complications of Covid-19 is venous thrombosis. Factors such as hospitalization, catheterization, hypoxia, inflammation, immobilization, and infection can increase VTE incidence. Therefore, this study aims to explore VTE indices as a predictor of mortality rates.
Methods: This Cross-Sectional retrospective study was conducted in our center, in Tehran, from April 18, 2020, to December 19, 2020. The study sampling was census, so that all patients with Covid-19 diagnosis were admitted according to the inclusion criteria. In addition, a researcher-made checklist form is used to collect patient information, including demographic information, medical history, clinical symptoms of Covid-19, and medical test results.
Results: The present study was conducted on 406 patients with a diagnosis of Covid-19. This study's results indicate that the Padua index> four increases the death rate of Covid-19 by 2.32 times. Also, IBS index > 7 increases the death rate of Covid-19 by 5.41 times, and D-dimer> 1 increases the death rate of Covid-19 by 3.93 times in Covid-19 patients. The results indicated that the Padua index was significantly correlated with IBS and D-dimer indices among the dead patients. D-dimer> 1 increases Padua index > 4 by 3.51 and IBS index > 7 by 3.29 times and IBS>7 increases the odds of Padua index > 4 by 11.48 times.
Conclusion: Patients with Covid-19 pneumonia often experience elevated Padua index, IBS index, and D-dimer values affecting mortality rates. Medical staff should focus on preventing high mortality rates through prophylaxis.
