OBJECTIVES To describe the characteristics and outcomes associated with concomitant renal and respiratory failure in patients with critical coronavirus disease 2019. DESIGN, SETTING, AND PATIENTS This is a case series of patients from a U.S. healthcare system in New York City. All adult patients (≥ 18 yr) admitted to the hospital with positive coronavirus disease 2019 testing between March 10, 2020, and March 31, 2020, who required mechanical ventilatory support were included. Patients who remained hospitalized were followed through May 1, 2020. INTERVENTIONS Renal replacement therapy included at least one session of dialysis, continued venovenous hemofiltration, or peritoneal dialysis. MEASUREMENTS AND MAIN RESULTS Baseline characteristics, laboratory markers, 30-day in-hospital outcomes, ventilator days, and survival to discharge were included. Multivariate predictors for mortality and need for renal replacement therapy were identified. A total of 330 patients were included in this analysis and were most commonly greater than or equal to 70 years (40%), male (61%), Black or African American (41%), and Hispanic or Latino (38%). Renal replacement therapy was required in 101 patients (29%), most commonly among Blacks or African Americans (50%). Elevated D-dimer, C-reactive protein, and procalcitonin were associated with renal replacement therapy, compared with the nondialysis cohort. Overall, 243 patients (74%) died and 56 (17%) were discharged from the hospital, of which 9 (3%) required renal replacement therapy. Male sex (odds ratio, 2.0; 1.1-3.5; p = 0.020), Black race (odds ratio, 1.8; 1.0-3.1; p = 0.453), and history of hypertension (odds ratio, 2.7; 1.3-5.4; p = 0.005) were predictors for requiring renal replacement therapy. Risk factors for in-hospital mortality included age greater than or equal to 60 years (odds ratio, 6.2; 3.0-13.0; p < 0.0001), male sex (odds ratio, 3.0; 1.4-6.4; p = 0.004), and body mass index greater than or equal to 30 kg/m (odds ratio, 2.1; 1.0-4.4; p = 0.039). Concomitant renal failure in critical coronavirus disease 2019 was not a significant predictor of death (odds ratio, 2.3; 0.98-5.5; p = 0.057). CONCLUSIONS This case series concludes that respiratory failure conveys significant mortality risk in patients with coronavirus disease 2019 and that survival with concomitant renal failure is rare.
