Abstract only 6503 Background: Many patients with advanced cancer maintain misperceptions of their prognosis and are thus unprepared to make difficult decisions regarding their end-of-life (EOL) care. However, studies examining the associations between patients’ perceptions of their prognosis and their EOL outcomes are limited. Methods: We conducted a secondary analysis using longitudinal data from a randomized controlled trial of a palliative care intervention for patients with newly diagnosed incurable lung and non-colorectal gastrointestinal cancer. We administered the Prognosis and Treatment Perceptions Questionnaire to assess patients’ perceptions of their prognosis at baseline, week-12, and week-24, using the final assessment closest to death. We used multivariate logistic and linear regression models, adjusting for age, gender, marital status, cancer type, and randomization to the palliative care intervention, to examine the associations among patients’ perceptions of their prognosis with the following EOL care outcomes abstracted from the electronic health record: 1) hospice utilization and length-of-stay (LOS); 2) hospitalizations in the last 30 days of life; 3) receipt of chemotherapy in the last 30 days of life; and 4) location of death. Results: We enrolled 350 patients in the parent trial, of which 80.5% (281/350) died during the study period and were included in this analysis. Overall, 59.4% (164/276) of patients reported that they were terminally ill, and 66.1% (154/233) reported that their cancer was likely curable at the assessment closest to death. In multivariate analyses, patients who reported that their cancer was likely curable were less likely to utilize hospice (OR = 0.25, 95%CI 0.10-0.61, P = 0.002) or die at home (OR = 0.56, 95%CI 0.32-0.98, P = 0.043), and more likely to be hospitalized in the last 30 days of life (OR = 2.28, 95%CI 1.20-4.32, P = 0.011). In contrast, patients’ report that they were terminally ill was only associated with lower likelihood of hospitalizations in the last 30 days of life (OR = 0.52, 95%CI 0.29-0.92, P = 0.025). Patients’ perceptions of their prognosis were not associated with hospice LOS or chemotherapy administration in the last 30 days of life. Conclusions: Patients’ perceptions of their prognosis are associated with important EOL outcomes including hospice utilization, hospitalizations at the EOL, and death at home. Interventions are needed to enhance patients’ perceptions of their prognosis in order to optimize their EOL care.
