ICU utilization among oncology patients at the end of life.

Abstract

118 Background: Patients with advanced cancer have high rates of hospitalizations as a result of their oncologic care. Furthermore, these patients receive aggressive end of life care despite evidence that aggressive end of life care does not improves quality of life or outcomes for patients and is associated with worse bereavement adjustment for caregivers. The American Society of Clinical Oncology has endorsed several indicators of aggressive end of life care, but most striking is intensive care unit (ICU) admission within 30 days before death. Methods: Adult oncology patients who died within 30 days of hospitalization and/or admitted to the ICU from 10/2018-3/2019 at an academic medical center were evaluated. The cohort was identified using ICD-10 codes, EMR systems support, and manual chart review. Patient demographic data, cancer type, stage, line of therapy, code status, advanced care plan, prior admissions as well as other clinical characteristics were collected. Results: In total, 180 patients were included for analysis; 106 of which were admitted to the ICU. Of patients admitted to the ICU, 58 patients died (54.7%). Mean ECOG performance status was 1.24. Average number of admissions 3 and 6 months prior to death was 0.71 and 1.26. Thirty six percent of patients were on first or second-line chemotherapy. 41.37% of patients who died in the ICU had prolonged length of stay (>1 week). Only 34.48% were known to palliative care prior to admission and 12.06% of patients had advanced care plans in place at time of hospitalization. Palliative care was consulted on 32.75% of patients who died in the ICU. Ninety Three percent had their code status changed prior to death. Conclusions: Despite established recommendations to support otherwise, at our institution there continues to be high utilization of ICU care near the end of life. Previous admissions and ECOG status are poor predictors of death in this cohort. The majority of patients had relapsed and refractory disease. There was a low rate of advanced care planning or palliative care involvement prior to the patient’s hospitalization. Further interventions are underway to improve end of life planning in order to improve our quality of care.
