    AbstractRationale: Allogeneic hematopoietic stem-cell transplantation (Allo-HSCT) recipients are still believed to be poor candidates for ICU management. Methods: We investigated outcomes and determinants of mortality in a large multicenter retrospective cohort of Allo-HSCT patients admitted between January 1, 2015, and December 31, 2020, to 14 French ICUs. The primary endpoint was 90-day mortality. Measurements and Main Results: In total, 1,164 patients were admitted throughout the study period. At the time of ICU admission, 765 (66%) patients presented with multiple organ dysfunction, including acute respiratory failure in 40% (n = 461). The median sepsis-related organ failure assessment score was 6 (interquartile range, 4-8). Invasive mechanical ventilation, renal replacement therapy, and vasopressors were required in 438 (38%), 221 (19%), and 468 (41%) patients, respectively. ICU mortality was 26% (302 deaths). Ninety-day, 1-year, and 3-year mortality rates were 48%, 63%, and 70%, respectively. By multivariable analysis, age > 56 years (odds ratio [OR], 2.0 [95% confidence interval (CI), 1.53-2.60]; P < 0.001), time from Allo-HSCT to ICU admission between 30 and 90 days (OR, 1.68 [95% CI, 1.17-2.40]; P = 0.005), corticosteroid-refractory acute graft-versus-host disease (OR, 1.63 [95% CI, 1.38-1.93]; P < 0.001), need for vasopressors (OR, 1.9 [95% CI, 1.42-2.55]; P < 0.001), and mechanical ventilation (OR, 3.1 [95% CI, 2.29-4.18]; P < 0.001) were independently associated with 90-day mortality. In patients requiring mechanical ventilation, mortality rates ranged from 39% (no other risk factors for mortality) to 100% (four associated risk factors for mortality). Conclusions: Most critically ill Allo-HSCT recipients survive their ICU stays, including those requiring mechanical ventilation, with an overall 90-day survival rate reaching 51.8%. A careful assessment of goals of care is required in patients with two or more risk factors for mortality.
