Key Points The persistence of a CEBPA mutation at the time of complete remission warrants germ line analysis. Not all patients harboring germ line CEBPA mutations have a family history of AML.

110 Background: Reducing the rate of hospital readmissions is an important aspect of improving quality of life and cost of care for patients with advanced cancer. Early Palliative Care (PC) has been shown to improve quality of life and downstream healthcare utilization in patients with advanced cancer. The aim of this study was to examine palliative care (PC) utilization and factors associated with 30-day readmission in cancer patients. Methods: All patients with 30 day readmissions to the inpatient oncology service at the Wilmot Cancer Institute from July 2015-June 2016 were identified. Chart reviews were conducted to determine primary cancer stage and type; reason for, length of stay and discharge disposition (e.g. discharged on hospice, deceased) for index and readmission; potential preventability of readmission; and if and when the patient had met with PC. Results: A total of thirty-nine patients experienced a 30-day readmission, with 95% of patients having stage IV disease and 77% having a primary lung or GI malignancy. Most patients (74%) had not met with PC at the time of the index admission and 49% of patients had not met with PC by the time of readmission. Forty one percent (N = 17) of patients either died during readmission or were discharged on hospice. Forty one percent (N = 7) of those that died during readmission or were discharged on hospice did not meet with palliative care. Forty four percent of readmissions were classified as potentially preventable. Conclusions: Nearly half of all advanced cancer patients had not met with PC by the time of their readmission. Upon readmission, many patients were either discharged to hospice or died, suggesting that patients with advanced cancer could benefit from earlier PC. Increased and improved patient-oncologist PC communication, including referrals to PC specialists, may reduce readmission rates for patients with advanced cancer.
