Abstract
Background: Increased estimated whole blood viscosity (eWBV) predicts higher mortality in patients hospitalized for coronavirus disease 2019 (COVID-19). This study assesses whether eWBV is an early predictor of non-fatal outcomes among patients hospitalized for acute COVID-19 infection.
Methods: This retrospective cohort study included 9278 hospitalized COVID-19 patients diagnosed within 48 h of admission between February 27, 2020 to November 20, 2021 within the Mount Sinai Health System in New York City. Patients with missing values for major covariates, discharge information, and those who failed to meet the criteria for the non-Newtonian blood model were excluded. 5621 participants were included in the main analysis. Additional analyses were performed separately for 4352 participants who had measurements of white blood cell count, C-reactive protein and D-dimer. Participants were divided into quartiles based on estimated high-shear blood viscosity (eHSBV) and estimated low-shear blood viscosity (eLSBV). Blood viscosity was calculated using the Walburn-Schneck model. The primary outcome was evaluated as an ordinal scale indicating the number of days free of respiratory organ support through day 21, and those who died in-hospital were assigned a value of -1. Multivariate cumulative logistic regression was conducted to evaluate the association between quartiles of eWBV and events.
Results: Among 5621 participants, 3459 (61.5%) were male with mean age of 63.2 (SD 17.1) years. The linear modeling yielded an adjusted odds ratio (aOR) of 0.68 (95% CI 0.59-0.79, p value < 0.001) per 1 centipoise increase in eHSBV.
Conclusions: Among hospitalized patients with COVID-19, elevated eHSBV and eLSBV at presentation were associated with an increased need for respiratory organ support at 21 days. These findings are highly relevant, as they demonstrate the utility of eWBV in identifying hospitalized patients with acute COVID-19 infection at increased risk for non-fatal outcomes in early stages of the disease.
期刊介绍:
"Journal of Intensive Care" is an open access journal dedicated to the comprehensive coverage of intensive care medicine, providing a platform for the latest research and clinical insights in this critical field. The journal covers a wide range of topics, including intensive and critical care, trauma and surgical intensive care, pediatric intensive care, acute and emergency medicine, perioperative medicine, resuscitation, infection control, and organ dysfunction.
Recognizing the importance of cultural diversity in healthcare practices, "Journal of Intensive Care" also encourages submissions that explore and discuss the cultural aspects of intensive care, aiming to promote a more inclusive and culturally sensitive approach to patient care. By fostering a global exchange of knowledge and expertise, the journal contributes to the continuous improvement of intensive care practices worldwide.
