This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
The COVID-19 pandemic continues to challenge the capacities of hospital ICUs which currently lack the ability to identify prospectively those patients who may require extended management. In this study of 90 ICU COVID-19 patients, we used multiplexed cytokine evaluation and, on 42 of these patients (binned into Initial and Replication Cohorts), CyTOF-based deep immunophenotyping. This revealed blood prognostic biomarkers that, at time of ICU admission, prospectively distinguish, with 91% sensitivity and 91% specificity, patients who will subsequently die or have long ICU stays (> 6 days) from those who will have short-stays (< 6 days). This is achieved through a tiered evaluation of serum IL-10 and targeted immunophenotyping of monocyte subsets (specifically, CD11clow classical monocytes) through statistical approaches. We have distilled this down to a prognostic test that could prove useful in guiding clinical resource allocation, treatment regimens and assessment of new therapeutic interventions.
