Association of blood viscosity and device-free days among hospitalized patients with COVID-19
Main finding · Respiratory organ support-free days, per 1 centipoise increase in eHSBVResult — go to the resultAdjusted odds ratio 0.68 95% CI 0.59–0.79Authors' conclusion
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.
Study context
- Population
- Hospitalized COVID-19 patients diagnosed within 48 h of admission, Mount Sinai Health System, New York City, February 27, 2020 to November 20, 20215,621 in main analysis
- Participants
- 9,278 patients
- Exposure
- Quartiles of estimated high-shear blood viscosity (eHSBV) and estimated low-shear blood viscosity (eLSBV)
- Outcome
- Ordinal scale of days free of respiratory organ support (in-hospital death = −1)
- Follow-up
- Day 21
