ABSTRACT

Background:

Hemorrhage, coagulopathy and thrombosis (HECTOR) are reported complications of coronavirus disease 2019 (COVID-19) however, more information is needed on the prevalence of these complications and their associated outcomes in intensive care unit (ICU) settings. Aim(s) To determine the prevalence and outcomes of HECTOR complications in ICU patients with COVID-19. Method(s) Observational cohort study spanning 229 ICUs across 32 countries. Patients >=16 years admitted for severe COVID-19 from 1st January 2020, through 31st December 2021 were included. Patient characteristics and clinical data were collected. Survival analysis estimated the instantaneous impact of HECTOR complications on ICU-mortality and discharge. Result(s) HECTOR complications occurred in 1,735 (14%) of 11,972 study-eligible patients. Acute thrombosis occurred in 1,249 (10%) patients, including 712 (57%) with pulmonary embolism, 413 (33%) with myocardial infarction, 93 (7.4%) with deep vein thrombosis, and 49 (3.9%) with ischemic stroke. Hemorrhagic complications were reported in 582 (4.9%) patients, including 276 (48%) with gastrointestinal hemorrhage, 83 (14%) with hemorrhagic stroke, and 77 (13%) with pulmonary hemorrhage. Disseminated intravascular coagulation occurred in 11 (0.09%) patients. Univariate analysis identified diabetes, hypertension, cardiac and kidney disease and ECMO as statistically-significant risk factors for HECTOR complications. Patients with versus without HECTOR complications suffered higher ICU-mortality at 28 days (25%vs.13%, p < 0.001), 90 days (32%vs.15%, p < 0.0001) and overall (44%vs.36%, p < 0.001). Among ICU survivors, the ICU stay was longer (median days 19vs.12, p < 0.001). ICU mortality was similar between patients with and without HECTOR complications (HR = 1.01, 95%CI 0.92-1.12, p = 0.783) where an increased hazard of ICU mortality with hemorrhage (HR = 1.26, 1.09-1.45, p = 0.002) was balanced by a reduced hazard of thrombosis (HR = 0.88, 0.79-0.99, p = 0.03). Kaplan-Meier curves are presented in the Figure. Conclusion(s) HECTOR events are frequent complications of severe COVID-19 in ICU patients. Hemorrhagic, but not thrombotic complications are associated with increased ICU-mortality.
