Palliative care models for patients living with advanced cancer: a narrative review for the emergency department clinician.

Eighty-one percent of persons living with cancer have an emergency department (ED) visit within the last 6 months of life. Many cancer patients in the ED are at an advanced stage with high symptom burden and complex needs, and over half is admitted to an inpatient setting. Innovative models of care have been developed to provide high quality, ambulatory, and home-based care to persons living with serious, life-limiting illness, such as advanced cancer. New care models can be divided into a number of categories based on either prognosis (e.g., greater than or less than 6 months), or level of care (e.g., lower versus higher intensity needs, such as intravenous pain/nausea medication or frequent monitoring), and goals of care (e.g., cancer-directed treatment versus symptom-focused care only). We performed a narrative review to (1) compare models of care for seriously ill cancer patients in the ED and (2) examine factors that may hasten or impede wider dissemination of these models.

Association of Race with End-of-Life Treatment Preferences in Older Adults with Cancer Receiving Outpatient Palliative Care.

Background: End-of-life discussions and documentation of preferences are especially important for older cancer patients who are at high risk of morbidity and mortality. Objective: To evaluate influence of demographic factors such as religiosity, education, income, race, and ethnicity on treatment preferences for end-of-life care. Methods: A retrospective observational study was performed on baseline data from a multisite randomized clinical trial of Dignity Therapy in 308 older cancer patients who were receiving outpatient palliative care (PC). Interviews addressed end-of-life treatment preferences, religion, religiosity and spirituality, and awareness of prognosis. End-of-life treatment preferences for care were examined, including preferences for general treatment, cardiopulmonary resuscitation (CPR), and mechanical ventilation (MV). Bivariate associations and multiple logistic regression analysis of treatment preferences with demographic and other baseline variables were conducted. Results: Our regression models demonstrated that race was a significant predictor for CPR preference and preferences for MV, although not for general treatment goals. Minority patients were more likely to want CPR and MV than whites. Men were more likely to opt for MV, although not for CPR or overall aggressive treatment, than women. Higher level of education was a significant predictor for preferences for less aggressive care at the end-of-life but not for CPR or MV. Higher level of terminal illness awareness was also a significant predictor for preferences for CPR, but not MV or aggressive care at the end-of-life. Discussion: Race was significantly associated with all three markers for aggressive care in bivariate analysis and with two out of three markers in multiple regression analysis, with minorities preferring aggressive care and whites preferring less aggressive care. Contrary to our hypothesis, income was not significantly associated with treatment preferences, whereas religion was significantly associated with all markers for aggressive care in bivariate models, but not in multiple regression models.

The Effect of Health Literacy on a Brief Intervention to Improve Advance Directive Completion: A Randomized Controlled Study.

OBJECTIVE: Completion of an advance directive (AD) document is one component of advanced care planning. We evaluated a brief intervention to enhance AD completion and assess whether the intervention effect varied according to health literacy. METHODS: A randomized controlled study was conducted in 2 internal medicine clinics. Participants were over 50, without documented AD, no diagnosis of dementia, and spoke English. Participants were screened for health literacy utilizing REALM-SF. Participants were randomized in a 1:1 ratio to the intervention, a 15-minute scripted introduction (grade 7 reading level) to our institution's AD forms (grade 11 reading level) or to the control, in which subjects were handed blank AD forms without explanation. Both groups received reminder calls at 1, 3, and 5 months. The primary outcome was AD completion at 6 months. RESULTS: Five hundred twenty-nine subjects were enrolled; half were of limited and half were of adequate health literacy. The AD completion rate was 21.7% and was similar in the intervention vs. the control group (22.4% vs 22.2%, P = .94).More participants with adequate health literacy completed an AD than those with limited health literacy (28.4% vs 16.2%, P = .0008), although the effect of the intervention was no different within adequate or limited literacy groups. CONCLUSION: A brief intervention had no impact on AD completion for subjects of adequate or limited health literacy. PRACTICE IMPLICATIONS: Our intervention was designed for easy implementation and to be accessible to patients of adequate or limited health literacy. This intervention was not more likely than the control (handing patients an AD form) to improve AD completion for patients of either limited or adequate health literacy. Future efforts and research to improve AD completion rates should focus on interventions that include: multiple inperson contacts with patients, contact with a trusted physician, documents at 5th grade reading level, and graphic/video decision aids.

Medical Cannabis for the Primary Care Physician.

Medical cannabis use is common in the United States and increasingly more socially acceptable. As more patients seek out and acquire medical cannabis, primary care physicians will be faced with a growing number of patients seeking information on the indications, efficacy, and safety of medical cannabis. We present a case of a patient with several chronic health conditions who asks her primary care provider whether she should try medical cannabis. We provide a review of the pharmacology of medical cannabis, the state of evidence regarding the efficacy of medical cannabis, variations in the types of medical cannabis, and safety monitoring considerations for the primary care physician.

Dignity Therapy Led by Nurses or Chaplains for Elderly Cancer Palliative Care Outpatients: Protocol for a Randomized Controlled Trial.

BACKGROUND: Our goal is to improve psychosocial and spiritual care outcomes for elderly patients with cancer by optimizing an intervention focused on dignity conservation tasks such as settling relationships, sharing words of love, and preparing a legacy document. These tasks are central needs for elderly patients with cancer. Dignity therapy (DT) has clear feasibility but inconsistent efficacy. DT could be led by nurses or chaplains, the 2 disciplines within palliative care that may be most available to provide this intervention; however, it remains unclear how best it can work in real-life settings. OBJECTIVE: We propose a randomized clinical trial whose aims are to (1) compare groups receiving usual palliative care for elderly patients with cancer or usual palliative care with DT for effects on (a) patient outcomes (dignity impact, existential tasks, and cancer prognosis awareness); and (b) processes of delivering palliative spiritual care services (satisfaction and unmet spiritual needs); and (2) explore the influence of physical symptoms and spiritual distress on the outcome effects (dignity impact and existential tasks) of usual palliative care and nurse- or chaplain-led DT. We hypothesize that, controlling for pretest scores, each of the DT groups will have higher scores on the dignity impact and existential task measures than the usual care group; each of the DT groups will have better peaceful awareness and treatment preference more consistent with their cancer prognosis than the usual care group. We also hypothesize that physical symptoms and spiritual distress will significantly affect intervention effects. METHODS: We are conducting a 3-arm, pre- and posttest, randomized, controlled 4-step, stepped-wedge design to compare the effects of usual outpatient palliative care and usual outpatient palliative care along with either nurse- or chaplain-led DT on patient outcomes (dignity impact, existential tasks, and cancer prognosis awareness). We will include 560 elderly patients with cancer from 6 outpatient palliative care services across the United States. Using multilevel analysis with site, provider (nurse, chaplain), and time (step) included in the model, we will compare usual care and DT groups for effects on patient outcomes and spiritual care processes and determine the moderating effects of physical symptoms and spiritual distress. RESULTS: The funding was obtained in 2016, with participant enrollment starting in 2017. Results are expected in 2021. CONCLUSIONS: This rigorous trial of DT will constitute a landmark step in palliative care and spiritual health services research for elderly cancer patients.

Early restriction of placental growth results in placental structural and gene expression changes in late gestation independent of fetal hypoxemia.

Placental restriction and insufficiency are associated with altered patterns of placental growth, morphology, substrate transport capacity, growth factor expression, and glucocorticoid exposure. We have used a pregnant sheep model in which the intrauterine environment has been perturbed by uterine carunclectomy (Cx). This procedure results in early restriction of placental growth and either the development of chronic fetal hypoxemia (PaO2≤17 mmHg) in late gestation or in compensatory placental growth and the maintenance of fetal normoxemia (PaO2>17 mmHg). Based on fetal PaO2, Cx, and Control ewes were assigned to either a normoxemic fetal group (Nx) or a hypoxemic fetal group (Hx) in late gestation, resulting in 4 groups. Cx resulted in a decrease in the volumes of fetal and maternal connective tissues in the placenta and increased placental mRNA expression of IGF2, vascular endothelial growth factor (VEGF), VEGFR-2, ANGPT2, and TIE2 There were reduced volumes of trophoblast, maternal epithelium, and maternal connective tissues in the placenta and a decrease in placental GLUT1 and 11ßHSD2 mRNA expression in the Hx compared to Nx groups. Our data show that early restriction of placental growth has effects on morphological and functional characteristics of the placenta in late gestation, independent of whether the fetus becomes hypoxemic. Similarly, there is a distinct set of placental changes that are only present in fetuses that were hypoxemic in late gestation, independent of whether Cx occurred. Thus, we provide further understanding of the different placental cellular and molecular mechanisms that are present in early placental restriction and in the emergence of later placental insufficiency.

Placental adaptations in growth restriction.

The placenta is the primary interface between the fetus and mother and plays an important role in maintaining fetal development and growth by facilitating the transfer of substrates and participating in modulating the maternal immune response to prevent immunological rejection of the conceptus. The major substrates required for fetal growth include oxygen, glucose, amino acids and fatty acids, and their transport processes depend on morphological characteristics of the placenta, such as placental size, morphology, blood flow and vascularity. Other factors including insulin-like growth factors, apoptosis, autophagy and glucocorticoid exposure also affect placental growth and substrate transport capacity. Intrauterine growth restriction (IUGR) is often a consequence of insufficiency, and is associated with a high incidence of perinatal morbidity and mortality, as well as increased risk of cardiovascular and metabolic diseases in later life. Several different experimental methods have been used to induce placental insufficiency and IUGR in animal models and a range of factors that regulate placental growth and substrate transport capacity have been demonstrated. While no model system completely recapitulates human IUGR, these animal models allow us to carefully dissect cellular and molecular mechanisms to improve our understanding and facilitate development of therapeutic interventions.
