Parenteral Hydration in Patients With Advanced Cancer: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial

PURPOSE The vast majority of patients with cancer at the end of life receive parenteral hydration in hospitals and no hydration in hospice, with limited evidence supporting either practice. In this randomized controlled trial, we determined the effect of hydration on symptoms associated with dehydration, quality of life, and survival in patients with advanced cancer. PATIENTS AND METHODS We randomly assigned 129 patients with cancer from six hospices to receive parenteral hydration (normal saline 1 L per day) or placebo (normal saline 100 mL per day) daily over 4 hours. The primary outcome was change in the sum of four dehydration symptoms (fatigue, myoclonus, sedation and hallucinations, 0 = best and 40 = worst possible) between day 4 and baseline. Secondary outcomes included Edmonton Symptom Assessment Scale (ESAS), Memorial Delirium Assessment Scale (MDAS), Nursing Delirium Screening Scale (NuDESC), Unified Myoclonus Rating Scale (UMRS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Dehydration Assessment Scale, creatinine, urea, and overall survival. Intention-to-treat analysis was conducted to examine the change by day 4 ± 2 and day 7 ± 2 between groups. RESULTS The hydration (n = 63) and placebo (n = 66) groups had similar baseline characteristics. We found no significant differences between the two groups for change in the sum of four dehydration symptoms (-3.3 v -2.8, P = .77), ESAS (all nonsignificant), MDAS (1 v 3.5, P = .084), NuDESC (0 v 0, P = .13), and UMRS (0 v 0, P = .54) by day 4. Results for day 7, including FACIT-F, were similar. Overall survival did not differ between the two groups (median, 21 v 15 days, P = .83). CONCLUSION Hydration at 1 L per day did not improve symptoms, quality of life, or survival compared with placebo.

Concepts and definitions for “supportive care,” “best supportive care,” “palliative care,” and “hospice care” in the published literature, dictionaries, and textbooks

PurposeCommonly used terms such as “supportive care,” “best supportive care,” “palliative care,” and “hospice care” were rarely and inconsistently defined in the palliative oncology literature. We conducted a systematic review of the literature to further identify concepts and definitions for these terms.MethodsWe searched MEDLINE, PsycInfo, EMBASE, and CINAHL for published peer-reviewed articles from 1948 to 2011 that conceptualized, defined, or examined these terms. Two researchers independently reviewed each citation for inclusion and then extracted the concepts/definitions when available. Dictionaries/textbooks were also searched.ResultsNine of 32 “SC/BSC,” 25 of 182 “PC,” and 12 of 42 “HC” articles focused on providing a conceptual framework/definition. Common concepts for all three terms were symptom control and quality-of-life for patients with life-limiting illness. “SC” focused more on patients on active treatment compared to other categories (9/9 vs. 8/37) and less often involved interdisciplinary care (4/9 vs. 31/37). In contrast, “HC” focused more on volunteers (6/12 vs. 6/34), bereavement care (9/12 vs. 7/34), and community care (9/12 vs. 6/34). Both “PC” and “SC/BSC” were applicable earlier in the disease trajectory (16/34 vs. 0/9). We found 13, 24, and 17 different definitions for “SC/BSC,” “PC,” and “HC,” respectively. “SC/BSC” was the most variably defined, ranging from symptom management during cancer therapy to survivorship care. Dictionaries/textbooks showed similar findings.ConclusionWe identified defining concepts for “SC/BSC,” “PC,” and “HC” and developed a preliminary conceptual framework unifying these terms along the continuum of care to help build consensus toward standardized definitions.

Palliative care development in Latin America: an analysis using macro indicators.

Background: Recently, the Latin American Association for Palliative Care developed 10 indicators to monitor the development of palliative care and enhance the development of regional and national strategies. Aim: To compare the status of palliative care development across Latin American nations using the Latin American Association for Palliative Care indicators and to classify the countries into three levels of palliative care development. Methods: A secondary analysis using the following indicators (number of indicators in each category): Policy (1), Education (3), Service Provision (3), and Opioids (3). A Latin American Association for Palliative Care Index was constructed adding the standard score (z-score) of each indicator. Setting/participants: Nineteen Spanish and Portuguese-speaking countries of Latin America. Results: Indicators significantly associated with the number of palliative care services per million inhabitants included: the proportion of medical schools with palliative care at the undergraduate level (p = 0.003), the number of accredited physicians working in palliative care (p = 0.001), and opioids consumed per capita (p = 0.032). According to the Latin American Association for Palliative Care Index, Costa Rica registered the highest score (8.1). Three ranking groups were built to measure palliative care development; Costa Rica, Chile, Mexico, and Argentina ranked in the high group, while Bolivia, Honduras, Dominican Republic, and Guatemala ranked in the lowest group. Conclusion: Most of the Latin American Association for Palliative Care indicators are useful for assessing national levels of palliative care development. These indicators may be applicable to other world regions. Additional studies are needed to evaluate the specificity of each indicator.

A multicenter survey of Hispanic caregiver preferences for patient decision control in the United States and Latin America

Background: Understanding family caregivers’ decisional role preferences is important for communication, quality of care, and patient and family satisfaction. The family caregiver has an important role in a patient’s decisional role preferences. There are limited studies on family caregivers’ preferences of the patient’s decision control at the end of life among Hispanics. Aims: To identify Hispanic caregivers’ preferences of the decision control of patients with advanced cancer and to compare the preferences of caregivers in Hispanic Latin American and Hispanic American caregivers. Design: We surveyed patients and their family caregivers referred to outpatient palliative care clinics in the United States, Chile, Argentina, and Guatemala. Caregiver preferences of patient’s decision control were evaluated using the Control Preference Scale. Caregivers’ and patients’ sociodemographic variables, patient performance status, and Hispanic American patient acculturation level were also collected. Participants: A total of 387 caregivers were surveyed: 100 (26%) in Chile, 99 (26%) in Argentina, 97 (25%) in Guatemala, and 91 (24%) in the United States. The median age was 56 years, and 59% were female. Results: Caregiver preference of patient’s decision control was passive, shared, and active for 10 (11%), 45 (52%), and 32 (37%) Hispanic American caregivers and 54 (19%), 178 (62%), and 55 (19%) Hispanic Latin American caregivers (p = 0.0023), respectively. Caregiver acculturation level did not affect the preferences of the Hispanic American sample (p = 0.60). Conclusions: Most Hispanic family caregivers preferred the patient to make shared decisions. Hispanic Latin American caregivers more frequently preferred patients to assume a passive decisional role. Acculturation did not influence the preferences of Hispanic American caregivers.

Practice Patterns and Perceptions About Parenteral Hydration in the Last Weeks of Life: A Survey of Palliative Care Physicians in Latin America

CONTEXT Parenteral hydration at the end of life is controversial and has generated considerable debate for decades. OBJECTIVES To identify palliative care physician parenteral hydration prescribing patterns and factors that influence prescribing levels (PLs) for patients during their last weeks of life. METHODS A cross-sectional, representative online survey of Latin American palliative care physicians was conducted in 2010. Physicians were asked to report the percentage of their terminally ill patients for whom they prescribed parenteral hydration. Predictors of parenteral hydration PLs were identified using logistic regression analysis. RESULTS Two hundred thirty-eight of 320 physicians completed the survey (74% response rate). Sixty percent of physicians reported prescribing parenteral hydration to 40%-100% of their patients during the last weeks of life. Factors influencing moderate/high PLs were the following: agreeing that parenteral hydration is clinically and psychologically efficacious (odds ratio [OR] 3.5; 95% confidence interval [CI] 1.5-8.3), disagreeing that withholding parenteral hydration alleviates symptoms (OR 3.3, 95% CI 1.3-8.1), agreeing that parenteral hydration is essential for meeting the minimum standards of care (OR 3.2, 95% CI 1.4-7.5), preferring the subcutaneous route of parenteral hydration for patient comfort and home use (OR 2.9, 95% CI 1.3-6.5), and being younger than 45 years of age (OR 2.6, 95% CI 1.3-5.2). CONCLUSION The strongest determinant of prescribing patterns was agreement with the clinical/psychological efficaciousness of parenteral hydration. Our results reflect parenteral hydration prescribing patterns and perceptions that substantially differ from the conventional/traditional hospice philosophy. These findings suggest that the decision to prescribe or withhold parenteral hydration is largely based on clinical perceptions and that most palliative care physicians from this region of the world individualize treatment decisions.

Colorectal Cancer Screening Among Latinos in Three Communities on the Texas–Mexico Border

Objective. To assess colorectal cancer screening (CRCS) prevalence and psychosocial correlates of CRCS among Latinos in South Texas. Method. Using multivariable analyses, we examined the association of perceived susceptibility, self-efficacy, pros and cons, subjective norms, knowledge and fatalism on CRCS among 544 Latinos (50 years and older). Results. In this socioeconomically disadvantaged population, 40% had never heard of any CRCS test, only 34% reported ever completing any type of CRCS, and only 25% were adherent to CRCS guidelines. Insurance status, gender, perceived cons, CRCS self-efficacy, and CRCS norms were significantly associated with CRCS. Conclusion. CRCS interventions in this population should focus on improving access, increasing self-efficacy and perceived norms, and decreasing negative perceptions of CRCS.

Treatment decisions for localized prostate cancer: A concept mapping approach

Few decision aids emphasize active surveillance (AS) for localized prostate cancer. Concept mapping was used to produce a conceptual framework incorporating AS and treatment.

From "Kickeando las malias" (Kicking the Withdrawals) to "Staying clean": The Impact of Cultural Values on Cessation of Injection Drug Use in Aging Mexican-American Men

Drug use among older adults is a growing concern, particularly for the burgeoning Hispanic population. Older adults seeking drug treatment will double over the next decade to almost 6 million. Cultural factors influence drug use, and more specifically, Hispanic cultural values influence heroin use. This study explored Mexican-American injection drug users’ adherence to traditional Hispanic cultural values and their impact on cessation. Ethnographic interviews endorsed contextualized influences of values on heroin use. Cultural values functioned dichotomously, influencing both initiation and cessation. Understanding the impact of cultural values on substance abuse is critical given the changing demographics in American society.

“El Lado Oscuro”: “The Dark Side” of Social Capital in Mexican American Heroin Using Men

This article describes social capital in a cohort of 227 Mexican American men who are long-term injection heroin users. Social capital scores for current and former users were similar, suggesting equal absolute values of capital, but associated with illicit activities in current users and with cessation efforts in former users. Stable drug-using relationships provided high negative capital, whereas conventional relationships provided positive capital. Thus, social capital functions dichotomously in positive and negative contextualized roles. This study provides an alternative understanding of the dynamic interactions between individuals, environment, and drug abuse and can inform prevention and treatment interventions for an important demographic group.
