OBJECTIVES: Differences in mortality rates previously reported in critically ill patients with coronavirus disease 2019 have increased the need for additional data on mortality and risk factors for death. We conducted this study to describe length of stay, mortality, and risk factors associated with in-hospital mortality in mechanically ventilated patients with coronavirus disease 2019. DESIGN: Observational study. SETTING: Two urban, academic referral hospitals in Indianapolis, Indiana. PATIENTS OR SUBJECTS: Participants were critically ill patients 18 years old and older, admitted with coronavirus disease 2019 between March 1, 2020, and April 27, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Outcomes included in-hospital mortality, duration of mechanical ventilation, and length of stay. A total of 242 patients were included with mean age of 59.6 years (sd, 15.5 yr), 41.7% female and 45% African American. Mortality in the overall cohort was 19.8% and 20.5% in the mechanically ventilated subset. Patients who died were older compared with those that survived (deceased: mean age, 72.8 yr [sd, 10.6 yr] vs patients discharged alive: 54.3 yr [sd, 14.8 yr]; p < 0.001 vs still hospitalized: 59.5 yr [sd, 14.4 yr]; p < 0.001) and had more comorbidities compared with those that survived (deceased: 2 [0.5-3] vs survived: 1 [interquartile range, 0-1]; p = 0.001 vs still hospitalized: 1 [interquartile range, 0-2]; p = 0.015). Older age and end-stage renal disease were associated with increased hazard of in-hospital mortality: age 65-74 years (hazard ratio, 3.1 yr; 95% CI, 1.2-7.9 yr), age 75+ (hazard ratio, 4.1 yr; 95% CI, 1.6-10.5 yr), and end-stage renal disease (hazard ratio, 5.9 yr; 95% CI, 1.3-26.9 yr). The overall median duration of mechanical ventilation was 9.3 days (interquartile range, 5.7-13.7 d), and median ICU length of stay in those that died was 8.7 days (interquartile range, 4.0-14.9 d), compared with 9.2 days (interquartile range, 4.0-14.0 d) in those discharged alive, and 12.7 days (interquartile range, 7.2-20.3 d) in those still remaining hospitalized.Conclusions:: We found mortality rates in mechanically ventilated patients with coronavirus disease 2019 to be lower than some previously reported with longer lengths of stay.
