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.
Hematopoietic stem cell transplantation (HCT) is an intensive and potentially curative therapy for patients with hematologic malignancies. Patients admitted for HCT experience a prolonged, isolating hospitalization and endure substantial physical and psychological symptoms. However, there is a paucity of research on the impact of HCT on post-traumatic stress disorder (PTSD) symptoms in transplant recipients. This secondary analysis of 250 patients who underwent autologous and allogeneic HCT examined PTSD using the PTSD Checklist-Civilian measured at 6 months after HCT. We used the Functional Assessment of Cancer Therapy-Bone Marrow Transplant, and the Hospital Anxiety and Depression Scale to assess quality of life (QOL) and depression and anxiety symptoms at the time of admission for HCT, week 2 during hospitalization, and 6 months after HCT. We used multivariate regression models to assess factors associated with PTSD symptoms. Given collinearity between QOL, depression, and anxiety symptoms, we modeled these separately. The rate of clinically significant PTSD symptoms at 6 months after HCT was 18.9% (39/206). Participants with clinically significant PTSD symptoms experienced hypervigilance (92.3%), avoidance (92.3%), and intrusion (76.9%) symptoms. Among patients without clinically significant PTSD symptoms, 24.5% had clinically significant hypervigilance symptoms and 13.7% had clinically significant avoidance symptoms. Lower QOL at time of HCT admission (B = -0.04, P = .004) and being single (B = -3.35, P = .027) were associated with higher PTSD symptoms at 6 months after HCT. Higher anxiety at time of HCT admission (B = 1.34, P <.001), change in anxiety during HCT hospitalization (B = 0.59, P =.006), and being single (B = -3.50, P = .017) were associated with higher PTSD symptoms at 6 months. In a separate model using depression, younger age (B = -0.13, P = .017), being single (B = -3.58, P = .018), and higher baseline depression symptoms were also associated with higher PTSD symptoms at 6 months (B = 0.97, P < .001). Approximately one fifth of patients undergoing HCT experience clinically significant PTSD symptoms at 6 months after transplantation. The prevalence of hypervigilance and avoidance symptoms are notable even among patients who do not have clinically significant PTSD symptoms. Interventions to prevent and treat PTSD symptoms in HCT recipients are clearly warranted.
Background: Patients (≥60 years) with acute myeloid leukemia (AML) often receive intense health care utilization at the end of life (EOL). However, factors associated with their health care use at the EOL are unknown. Methods: We conducted a secondary analysis of 168 deceased patients with AML within the United States. We assessed quality of life (QOL) (Functional-Assessment-Cancer-Therapy-Leukemia), and psychological distress (Hospital-Anxiety-and-Depression Scale [HADS]; Patient-Health-Questionnaire-9 [PHQ-9]) at diagnosis. We used multivariable logistic regression models to examine the association between patient-reported factors and the following outcomes: (1) hospitalizations in the last 7 days of life, (2) receipt of chemotherapy in the last 30 days of life, and (3) hospice utilization. Results: About 66.7% (110/165) were hospitalized in the last 7 days of life, 51.8% (71/137) received chemotherapy in the last 30 days of life, and 40.7% (70/168) utilized hospice. In multivariable models, higher education (odds ratio [OR] = 1.54, p = 0.006) and elevated baseline depression symptoms (PHQ-9: OR = 1.09, p = 0.028) were associated with higher odds of hospitalization in the last seven days of life, while higher baseline QOL (OR = 0.98, p = 0.009) was associated with lower odds of hospitalization at the EOL. Higher baseline depression symptoms were associated with receipt of chemotherapy at the EOL (HADS-Depression: OR = 1.10, p = 0.042). Higher education was associated with lower hospice utilization (OR = 0.356, p = 0.024). Conclusions: Patients with AML who are more educated, with higher baseline depression symptoms and lower QOL, were more likely to experience high health care utilization at the EOL. These populations may benefit from interventions to optimize the quality of their EOL care.
Background: Social support plays a crucial role for patients with aggressive hematologic malignancies as they navigate their illness course. The aim of this study was to examine associations of social support with overall survival (OS) and healthcare utilization in this population. Methods: A cross-sectional secondary analysis was conducted using data from a prospective longitudinal cohort study of 251 hospitalized patients with aggressive hematologic malignancies at Massachusetts General Hospital from 2014 through 2017. Natural Language Processing (NLP) was used to identify the extent of patients’ social support (limited vs adequate as defined by NLP-aided chart review of the electronic health record). Multivariable regression models were used to examine associations of social support with (1) OS, (2) death or readmission within 90 days of discharge from index hospitalization, (3) time to readmission within 90 days, and (4) index hospitalization length of stay. Results: Patients had a median age of 64 years (range, 19–93 years), and most were White (89.6%), male (68.9%), and married (65.3%). A plurality of patients had leukemia (42.2%) followed by lymphoma (37.9%) and myelodysplastic syndrome/myeloproliferative neoplasm (19.9%). Using NLP, we identified that 8.8% (n=22) of patients had limited social support. In multivariable analyses, limited social support was associated with worse OS (hazard ratio, 2.00; P =.042) and a higher likelihood of death or readmission within 90 days of discharge (odds ratio, 3.11; P =.043), but not with time to readmission within 90 days or with index hospitalization length of stay. Conclusions: In this cohort of hospitalized patients with aggressive hematologic malignancies, we found associations of limited social support with lower OS and a higher likelihood of death or readmission within 90 days of hospital discharge. These findings underscore the utility of NLP for evaluating the extent of social support and the need for larger studies evaluating social support in patients with aggressive hematologic malignancies.
Significance The United States performed nuclear testing on Bikini and Enewetak Atolls in the northern Marshall Islands between 1946 and 1958. Fallout from the largest test Bravo, detonated in 1954, spread over a large area, exposing to radiation not only land and ocean but also Marshallese people living in neighboring atolls, including Rongelap and Utirik. Cesium-137, present in the fallout, has a half-life of approximately 30 y and is readily absorbed by food crops, thus representing a health hazard for island inhabitants. In situ measurements of cesium-137 content were made for fruits from 11 islands on four atolls. Contamination remains above limits set by international safety standards in some measured fruits, and several islands display contamination from this human-made radionuclide.
