Abstract:
4 Background: Advance care planning (ACP) should be initiated early and readdressed often for cancer patients. We hypothesize that a rules-based algorithm can predict decreased overall survival, and can be used to target patients who would benefit from readdressing ACP. Methods: We performed a retrospective analysis of 219 patients receiving palliative chemotherapy with leukemia, cholangiocarcinoma, esophageal, gastric, pancreatic, lung or urothelial cancer at the University of Chicago Medicine. Patients were included if they had an index outpatient oncology visit from April 1, 2015 through June 30, 2015. We examined a three-month window from the index visit for a “high-risk event,” defined as: 1. change in chemotherapy 2. emergency department visit 3. hospitalization. Patients were followed from index visit until date of death or last clinical encounter as of January 31, 2017. Each “high-risk event” was treated as a time-varying covariate in a Cox proportional hazards regression model to calculate a hazard ratio of death compared to those without an event. Results: Sixty-seven percent of patients (146/219) experienced at least one high-risk event. A change in chemotherapy regimen, an ED visit, and a hospitalization occurred in 54% (118/219), 10% (22/219) and 26% (57/219) of patients respectively. The hazard ratio of death for patients with at least one high-risk event when compared to those without was 1.72 (95% CI: 1.19-2.46, p=0.003), when adjusted for age, gender, race, marital status, disease type, ECOG, and Charlson score. Inpatient admission independently reached significant for hazard of death. (HR 2.74: 95% CI: 1.84-4.09, p 〈 0.001). Conclusions: The rules-based algorithm identified patients with a greater risk of death. Implementation of this algorithm in the electronic medical record can identify patients with increased urgency to readdress goals of care. [Table: see text]
