Epidemiology and prognosis of patients with a history of cancer admitted to intensive care. A multicenter observational study

To assess the epidemiology and outcome at discharge of cancer patients requiring admission to the Intensive Care Unit (ICU). A descriptive observational study was made of data from the ENVIN-HELICS registry, combined with specifically compiled variables. Comparisons were made between patients with and without neoplastic disease, and groups of cancer patients with a poorer outcome were identified. Intensive Care Units participating in ENVIN-HELICS 2018, with voluntary participation in the oncological registry. Subjects admitted during over 24 h and diagnosed with cancer in the last 5 years. The general epidemiological endpoints of the ENVIN-HELICS registry and cancer-related variables. Of the 92 ICUs with full data, a total of 11,796 patients were selected, of which 1786 (15.1%) were cancer patients. The proportion of cancer patients per Unit proved highly variable (1%–48%). In-ICU mortality was higher among the cancer patients than in the non-oncological subjects (12.3% versus 8.9%; p
