PURPOSE Cancer-related fatigue (CRF) is the most common symptom in patients with advanced cancer. The primary objective of this prospective, randomized, double-blind, placebo-controlled study was to compare the effect of dexamethasone and placebo on CRF. PATIENTS AND METHODS Patients with advanced cancer with ≥ three CRF-related symptoms (ie, fatigue, pain, nausea, loss of appetite, depression, anxiety, or sleep disturbance) ≥ 4 of 10 on the Edmonton Symptom Assessment Scale (ESAS) were eligible. Patients were randomly assigned to either dexamethasone 4 mg or placebo orally twice per day for 14 days. The primary end point was change in the Functional Assessment of Chronic Illness-Fatigue (FACIT-F) subscale from baseline to day 15. Secondary outcomes included anorexia, anxiety, depression, and symptom distress scores. RESULTS A total of 84 patients were evaluable (dexamethasone, 43; placebo, 41). Mean (± standard deviation) improvement in the FACIT-F subscale at day 15 was significantly higher in the dexamethasone than in the placebo group (9 [± 10.3] v 3.1 [± 9.59]; P = .008). The improvement in FACIT-F total quality-of-life scores was also significantly better for the dexamethasone group at day 15 (P = .03). The mean differences in the ESAS physical distress scores at day 15 were significantly better for the dexamethasone group (P = .013, respectively). No differences were observed for ESAS overall symptom distress (P = .22) or psychological distress score (P = .76). Frequency of adverse effects was not significantly different between groups (41 of 62 v 44 of 58; P = .14). CONCLUSION Dexamethasone is more effective than placebo in improving CRF and quality of life in patients with advanced cancer.

PURPOSE Alcoholism is a devastating disease that can cause patient and family suffering and is frequently underdiagnosed. Preliminary studies suggest that it is associated with increased symptom expression and opioid dose escalation. The CAGE questionnaire is a widely used tool for alcoholism screening. The purpose of this study was to determine the frequency and characteristics of patients who screen positive for alcoholism in a palliative care outpatient clinic (PCOC). METHODS We reviewed 665 consecutive charts of patients referred to the PCOC and collected data regarding age, gender, and type of cancer. For the first 100 consecutive CAGE positive (CAGE+) and 100 consecutive CAGE negative (CAGE-) patients, time from advanced cancer diagnosis (AC) to PCOC was calculated, and symptoms (Edmonton Symptom Assessment Scale, ESAS) and Morphine Equivalent Daily Dose (MEDD) were collected. RESULTS CAGE was available for 598 of 665 (90%) patients. Of 598 patients, 100 (17%) were CAGE+. CAGE+ patients were younger (58 versus 60 years, p < 0.05), predominantly male (68% versus 47%, p < 0.0001), and with head/neck malignancies (24% versus 9%, p < 0.05). CAGE+ patients were referred earlier (5 +/- 27 months after AC, p < 0.0001). At baseline, pain, sleep, dyspnea, well-being, and total symptom distress were significantly worse among CAGE+ patients. Both groups showed similar improvement in symptoms. CAGE+ patients were more frequently on opioids upon referral (47/100 versus 29/100, p < 0.05) and follow-up (27/65 versus 16/68, p < 0.05). At follow-up, opioid doses did not show significant changes. CONCLUSION Seventeen percent of the patients were CAGE+. These patients were referred earlier to palliative care, had more symptom expression, and were more frequently on opioids. The palliative care team successfully improved symptom control in both groups without opioid dose escalation.

Limited research is available on the frequency of spiritual distress and its relationship with physical and emotional distress. We reviewed patients admitted to our acute palliative care unit (APCU) and determined the association between patient characteristics, symptom severity using the Edmonton Symptom Assessment scale (ESAS), and spiritual distress as reported by a chaplain on initial visit. In all, 50 (44%) of 113 patients had spiritual distress. In univariate analysis, patients with spiritual distress were more likely to be younger (odds ratio [OR] = 0.96, P = .004), to have pain (OR = 1.2, P = .010) and depression (OR = 1.24, P = .018) compared to those without spiritual distress. Spiritual distress was associated with age (OR = 0.96, P = .012) and depression (OR = 1.27, P = .020) in multivariate analysis. Our findings support regular spiritual assessment as part of the interdisciplinary approach to optimize symptom control.

CONTEXT Sleep disturbance (SD) is a significant source of distress for patients with cancer. Studies of patients with advanced cancer receiving palliative care to identify symptoms associated with the severity of SD are limited. OBJECTIVES In this study, we sought to identify the symptoms measured by the Edmonton Symptom Assessment Scale (ESAS) that are associated with SD, as measured by the Pittsburgh Sleep Quality Index (PSQI). Secondary aims of the study were to determine the association between occurrences of SD with occurrences of other symptoms and screening performance of the ESAS-Sleep item against the PSQI. METHODS We reviewed the completed ESAS and PSQI assessments of 101 patients with advanced cancer who were receiving palliative care and had been admitted to prospective clinical trials previously initiated by us. Patients with a PSQI score of ≥ 5 were considered to have an SD. The frequency and severity of the ESAS symptoms items, their correlation with each other, the PSQI score, and the screening performance of the ESAS-Sleep item were calculated. RESULTS The median age of patients was 60 years. Most were white non-Hispanic (73%), had lung or breast cancer (41%), and were diagnosed with SD (85%). The PSQI score was correlated with the ESAS items of pain (r=0.27, P=0.006), dyspnea (r=0.25, P<0.001), well-being (r=0.35, P<0.0001), and sleep (r=0.44, P<0.0001). Compared with patients without SD, those with SD were more likely to report pain (P=0.0132), depression (P=0.019), anxiety (P=0.01), and a poorer sense of well-being (P=0.035). An ESAS-Sleep item cutoff score of ≥ 3 (of 10) resulted in a sensitivity of 74% and a specificity of 73%. CONCLUSION SD is associated with increased frequency of pain, depression, anxiety, and a worse sense of well-being. These four symptoms should be assessed in all patients with advanced cancer with a complaint of SD. The ideal cutoff point of the ESAS-Sleep item for screening for SD is a score of ≥ 3. More research is needed to better characterize this frequent and distressing syndrome.

Background: Caregivers of patients with advanced cancer often face physical, social, and emotional distress as well as spiritual pain. Limited research has focused on the spiritual aspects of caregivers’ suffering in the palliative care setting. Methods: We interviewed 43 caregivers of patients with advanced cancer in our palliative care outpatient clinic. We determined demographic characteristics, religious affiliation, and relationship to the patient. Levels of spirituality, religiosity, and spiritual pain were self-reported using numeric rating scales (0 = lowest; 10 = highest). The participants completed various validated questionnaires to assess sleep disturbances, psychosocial distress, coping skills, and quality of life (QOL). Results: The median age was 52 years(range, 21-83); 29 (67%) were women, 34 (78%) were white, 7 (17%) were African American, and 2 (5%) were Hispanic; 39 (91%) were Christian, 1 (2%) was Jewish, and 1 (2%) was agnostic; 37(86%) were married; 18 (42%) were working full time; and 25(58%) were spouses. All considered themselves spiritual, and 98% considered themselves religious, with median scores of 8 (interquartile range, 6-10) and 8 (interquartile range, 4-9), respectively. All the caregivers reported that spirituality and religiosity helped them cope with their loved one’s illness, and many reported that spirituality and religiosity had a positive impact on their loved one’s physical (58%) and emotional (76%) symptoms. Spiritual pain was reported by 23 (58%), with a median score of 5 (interquartile range, 2-8). Caregivers with spiritual pain had higher levels of anxiety (median 10 vs 4; P = .002), depression (6 vs 2; P = .006), and denial (3 vs 2; P = .01); more behavioral disengagement (3 vs 2; P = 0.011) more dysfunctional coping strategies (19 vs 16; P < .001) and worse QOL (70 vs 51; P < .001) than those who did not have spiritual pain. Conclusions: The majority of caregivers of patients with advanced cancer considered themselves spiritual and religious. Despite this, there is high prevalence of spiritual pain in this population. Caregivers with spiritual pain experienced worse psychological distress and worse QOL. These findings support the importance of spiritual assessment of and spiritual support for caregivers in this setting.

CONTEXT Admissions to the emergency department (ED) can be distressing to patients with advanced cancer receiving palliative care. There is limited research about the clinical characteristics of these patients and whether these ED visits can be categorized as avoidable or unavoidable. OBJECTIVES To determine the frequency of potentially avoidable ED visits (AvEDs) for patients with advanced cancer receiving outpatient palliative care in a large tertiary cancer center, identify the clinical characteristics of the patients receiving palliative care who visited the ED, and analyze the factors associated with AvEDs and unavoidable ED visits (UnAvEDs). METHODS We randomly selected 200 advanced cancer patients receiving treatment in the outpatient palliative care clinic of a tertiary cancer center who visited the ED between January 2010 and December 2011. Visits were classified as AvED (if the problem could have been managed in the outpatient clinic or by telephone) or UnAvED. RESULTS Forty-six (23%) of 200 ED visits were classified as AvED, and 154 (77%) of 200 ED visits were classified as UnAvED. Pain (71/200, 36%) was the most common chief complaint in both groups. Altered mental status, dyspnea, fever, and bleeding were present in the UnAvED group only. Infection, neurologic events, and cancer-related dyspnea were significantly more frequent in the UnAvED group, whereas constipation and running out of pain medications were significantly more frequent in the AvED group (P < 0.001). In a multivariate analysis, AvED was associated with nonwhite ethnicity (odds ratio [OR] 2.66; 95% CI 1.26, 5.59) and constipation (OR 17.08; 95% CI 3.76, 77.67), whereas UnAvED was associated with ED referral from the outpatient oncology or palliative care clinic (OR 0.24; 95% CI 0.06, 0.88) and the presence of baseline dyspnea (OR 0.46; 95% CI 0.21, 0.99). CONCLUSION Nearly one-fourth of ED visits by patients with advanced cancer receiving palliative care were potentially avoidable. Proactive efforts to improve communication and support between scheduled appointments are needed.

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.
