Two Decades of ICU Utilization and Hospital Outcomes in a Comprehensive Cancer Center
Abstract
To investigate ICU utilization and hospital outcomes of oncological patients admitted to a comprehensive cancer center. Observational cohort study. The University of Texas MD Anderson Cancer Center. Consecutive adults with cancer discharged over a 20-year period. None. The Cochran-Armitage test for trend was used to evaluate ICU utilization and hospital mortality rates by primary service over time. A negative binomial log linear regression model was fitted to the data to investigate length of stay over time. Among 387,306 adult hospitalized patients, the ICU utilization rate was 12.9%. The overall hospital mortality rate was 3.6%: 16.2% among patients with an ICU stay and 1.8% among non-ICU patients. Among those admitted to the ICU, the mean (SD) admission Sequential Organ Failure Assessment score was 6.1 (3.8) for all ICU patients: 7.3 (4.4) for medical ICU patients and 4.9 (2.8) for surgical ICU patients. Hematologic disorders were associated with the highest hospital mortality rate in ICU patients (42.8%); metastatic disease had the highest mortality rate in non-ICU patients (4.2%); sepsis, pneumonia, and other infections had the highest mortality rate for all inpatients (8.5%). This study provides a longitudinal view of ICU...Continue Reading
