This overprediction of mortality was also observed in the MIMIC-III database, with 4847 deaths observed compared with 6113 expected deaths predicted by the OASIS model. Length of stay in intensive care unit, daysġ0 562 deaths were observed in the eICU-CRD, compared with 14 097 deaths predicted by the APACHE IVa model ( appendix p 5). Table 1 Patient characteristics by database Out of the three scoring systems, SOFA has come to be used (in guidelines) for initial ICU triage purposes and to determine the continuation of mechanical ventilation in situations of limited resources during a pandemic. We chose to examine three of these systems (Acute Physiology and Chronic Health Evaluation IVa, Oxford Acute Severity of Illness Score, and Sequential Organ Failure Assessment ) for possible ethnically based bias. However, none of the currently employed ICU severity scoring systems incorporate ethnicity or other relevant socioeconomic factors as a parameter in their analysis. Ethnicity is generally documented in the process of hospital admission.
These systems are used in critical care medicine for severity adjustment for research purposes and for benchmarking intensive care unit (ICU) performance. We searched PubMed on Sept 4, 2020, with no filter restrictions, using the terms, “intensive care unit severity scoring systems”, “bias”, and “racial bias” and found no results.
