Causes of Death Among Medical ICU Patients With Pneumonia Due to COVID-19 in a Safety-Net Hospital.
We sought to identify the primary causes of death of adult patients admitted to the medical ICU with symptomatic COVID-19 who ultimately suffered in-hospital mortality over the span of three major waves of COVID-19: Wild-type, alpha/epsilon, and delta.
Design: Retrospective single-center cohort study from March 2020 to December 2021.
Setting: One medical ICU in a 600-bed Tertiary Care Hospital in Los Angeles, CA.
Patients: Adult (n = 306) ICU patients admitted with symptomatic COVID-19 who suffered in-hospital mortality.
Interventions: None.
Main results: Of the 306 patients with COVID-19 who died in the hospital, 86.3% were Hispanic/Latino. The leading cause of death was respiratory failure, occurring in 57.8% of patients. There was no significant change in the rate of pulmonary deaths across the three waves of COVID-19 in our study period. The mean time from symptom onset to admission was 6.5 days, with an average hospital length of stay of 18 days. This did not differ between pulmonary and other causes of death. Sepsis was the second most common cause of death at 23.9% with a significant decrease from the wild-type wave to the delta wave. Among patients with sepsis as the cause of death, 22% (n = 16) were associated with fungemia. There was no significant association between steroid administration and cause of death. Lastly, the alpha/epsilon wave from December 2020 to May 2021 had the highest mortality rate when compared with wild-type or delta waves.
Conclusions: We found the primary cause of death in ICU patients with COVID-19 was acute respiratory failure, without significant changes over the span of three waves of COVID-19. This finding contrasts with reported causes of death for patients with non-COVID-19 acute respiratory distress syndrome, in which respiratory failure is an uncommon cause of death. In addition, we identified a subset of patients (5%) who died primarily due to fungemia, providing an area for further investigation.
