PurposeAlthough admitting cancer patients to the ICU is no longer an issue, it may be valuable to identify patients perceived least likely to benefit from admission. Our objective was to investigate factors associated with potentially inappropriate ICU admission.MethodsRetrospective cohort study of patients with cancer with unplanned ICU admission. We classified admissions as appropriate or potentially inappropriate according to Society of Critical Care Medicine guidelines. We used logistic regression model to assess factors associated with inappropriateness for ICU admission.ResultsFrom 3384 patients, 663 (19.6%) were classified as potentially inappropriate. They received more invasive mechanical ventilation (25.3% vs 12.5%, P < 0.001) and vasopressors (34.4% vs 30.1%, P = 0.034), had higher ICU [3 (2,6) vs 2 (1,4), P < 0.001] length-of-stay, higher ICU (32.7% vs 8.4%, P < 0.001), hospital (71.9% vs 21.3%, P < 0.001), and one-year mortality (97.6% vs 54.7%, P < 0.001) compared with those considered appropriate. Performance status impairment, more severe organ dysfunctions at admission, metastatic disease, and source of ICU admission were the characteristics associated with intensivist's perception of inappropriateness of ICU admission.ConclusionsThese findings may help guide ICU admission policies and triage criteria for end-of-life discussions among hospitalized patients with cancer.Copyright © 2023 Elsevier Inc.
