Survival in critically ill admissions with and without COVID-19 at an academic medical center during the height of the pandemic

Objective: Early reports demonstrate that patients with Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection have high rates of hospitalization, intensive care unit (ICU) admission, and death. We sought to examine characteristics of ICU admissions with and without Coronavirus 2019 (COVID-19) and to compare outcomes between these two critically ill cohorts.
Methods: A retrospective analysis of 600 unique adult ICU admissions was conducted at an academic medical center in Boston, MA from March 22 to May 31, 2020.
Results: Of 600 ICU admissions, 170 (28.3%) tested positive for COVID-19. Those with COVID-19 had greater severity of illness and were more likely to require mechanical ventilation (MV). Hospital and ICU mortality rates were greater in the COVID-19 group (22.4% vs. 9.5%; 18.2% vs. 7.2%, respectively), but lower than previous reports. Unadjusted odds ratio (OR) for COVID-19 as a predictor of hospital mortality was 2.73 (95% CI 1.68 to 4.43), but when accounting for clinical characteristics and severity of illness, adjusted OR for hospital mortality was no different (1.09 [95% CI 0.50 to 2.41]) among those with and without COVID-19.
Conclusions: COVID-19 admissions had greater severity of illness and suffered higher crude mortality rates compared to the non-COVID-19 cohort. However, there was no significant difference in the adjusted OR for hospital mortality between patients with and without COVID-19. This novel finding may be attributed to the “learning curve” from other healthcare system experiences, early hospital-wide preparation, and dedicated intensive care.
