Exploring the meaning of dignity at end of life for Chinese Canadians caregivers: A qualitative cross-cultural study.

BACKGROUND: Preserving patient dignity is a fundamental value in palliative care and is associated with an increased sense of meaning at end of life. The empiric Dignity Model, developed by Chochinov et al. (2002), identifies physical and psychosocial issues impacting dignity and provides guidance for dignity conserving care. AIM: This study's objectives are to explore the generalizability of the empiric Dignity Model to Chinese Canadians an immigrant population influenced by both Western and Asian values. The study will explore how dignity is culturally mediated. DESIGN: Template analysis using NVivo was used to assess for themes and to explore new themes in focus group interviews. PARTICIPANTS: Three focus groups of thirty-one first generation Chinese Canadians were conducted in the community setting, in the metropolitan area of Greater Vancouver. RESULTS: The three thematic categories of the Dignity Model were broadly supported. Themes of Family connectedness and the Confucian virtue of filial piety (duty that children have towards their parents), were found to be strongly relevant for Chinese Canadians. Subjects' acculturation within Canada led to an evolution of perception of dignity as new ideas are accepted or rejected and blended with pre-existing values. CONCLUSION: To the author's knowledge this is the first study on the Dignity Model done in a Chinese Canadian population. The conceptualization of dignity for first generation Chinese Canadians is influenced by both Western and Asian culture. This study highlights the unique constructs of dignity for Chinese Canadians and areas to enhance dignity preserving care in a cross-cultural context.

Standardized patient simulation versus didactic teaching alone for improving residents' communication skills when discussing goals of care and resuscitation: A randomized controlled trial.

BACKGROUND: Communication skills are important when discussing goals of care and resuscitation. Few studies have evaluated the effectiveness of standardized patients for teaching medical trainees to communicate about goals of care. OBJECTIVE: To determine whether standardized patient simulation offers benefit over didactic sessions alone for improving skill and comfort discussing goals of care. DESIGN AND INTERVENTION: Single-blind, randomized, controlled trial of didactic teaching plus standardized patient simulation versus didactic teaching alone. PARTICIPANTS: First-year internal medicine residents. MAIN MEASURES: Changes in communication comfort and skill between baseline and 2 months post-training assessed using the Consultation and Relational Empathy measure. KEY RESULTS: We enrolled 94 residents over a 2-year period. Both groups reported a significant improvement in comfort when discussing goals of care with patients. There was no difference in Consultation and Relational Empathy scores following the workshop ( p = 0.79). The intervention group showed a significant increase in Consultation and Relational Empathy scores post-workshop compared with pre-workshop (35.0 vs 31.7, respectively; p = 0.048), whereas there was no improvement in Consultation and Relational Empathy scores in the control group (35.6 vs 36.0; p = 0.4). However, when the results were adjusted for baseline differences in Consultation and Relational Empathy scores in a multivariable regression analysis, group assignment was not associated with an improvement in Consultation and Relational Empathy score. Improvement in comfort scores and perception of benefit were not associated with improvements in Consultation and Relational Empathy scores. CONCLUSION: Simulation training may improve communication skill and comfort more than didactic training alone, but there were important confounders in this study and further studies are needed to determine whether simulation is better than didactic training for this purpose.

The oncology palliative care clinic at the Princess Margaret Cancer Centre: an early intervention model for patients with advanced cancer.

Several recently published randomized controlled trials have demonstrated the benefits of early palliative care involvement for patients with advanced cancer. In the oncology outpatient setting, palliative care clinics are an ideal site for the provision of early, collaborative support, which can be maintained throughout the cancer trajectory. Despite this, access to ambulatory palliative care clinics is limited, even at tertiary cancer centres. Existing programs for outpatient palliative care are variable in scope and are not well described in the literature. We describe the development and expansion of an outpatient palliative care clinic at the Princess Margaret Cancer Centre, Toronto, Canada, demonstrating how the clinic functions at a local and regional level. This clinic served as the intervention for a recent large cluster-randomized trial of early palliative care. The model for this service can be adapted by other palliative care programs that aim to provide early, integrated oncology care.

Deciphering the peptidome of urine from ovarian cancer patients and healthy controls.

BACKGROUND: Ovarian cancer (OvCa) is the most lethal gynecological malignancy. The emergence of high-throughput technologies, such as mass spectrometry, has allowed for a paradigm shift in the way we search for novel biomarkers. Urine-based peptidomic profiling is a novel approach that may result in the discovery of noninvasive biomarkers for diagnosing patients with OvCa. In this study, the peptidome of urine from 6 ovarian cancer patients and 6 healthy controls was deciphered. RESULTS: Urine samples underwent ultrafiltration and the filtrate was subjected to solid phase extraction, followed by fractionation using strong cation exchange chromatography. These fractions were analyzed using an Orbitrap mass spectrometer. Over 4600 unique endogenous urine peptides arising from 713 proteins were catalogued, representing the largest urine peptidome reported to date. Each specimen was processed in triplicate and reproducibility at the protein (69-76%) and peptide (58-63%) levels were noted. More importantly, over 3100 unique peptides were detected solely in OvCa specimens. One such promising biomarker was leucine-rich alpha-2-glycoprotein (LRG1), where multiple peptides were found in all urines from OvCa patients, but only one peptide was found in one healthy control urine sample. CONCLUSIONS: Mining the urine peptidome may yield highly promising novel OvCa biomarkers.

Methadone for Pain Management in Chemotherapy-Induced Peripheral Neuropathy: A Retrospective Review.

Chemotherapy-Induced Peripheral Neuropathy (CIPN) refers to damage of peripheral nerve fibers due to the use of neurotoxic chemotherapy to treat various cancers. It occurs in more than 30% of patients and only duloxetine has currently been identified to show limited efficacy in symptomatic treatment of CIPN. Opioids have traditionally been used to treat cancer pain, and there is evidence for their use in treatment of peripheral neuropathic pain from other causes. With a similar mechanism of action to duloxetine, methadone has rationale for treating neuropathic pain. This study is a retrospective chart review to evaluate the outcomes of using methadone for CIPN pain. Out of 31 patients, 65% felt that methadone was an effective treatment, 19% felt that it was ineffective, and 16% felt that it was partially or temporarily effective. These results suggest that analgesic response to methadone varies between patients, but that it has a potential role in painful CIPN. Its advantages for long-term use include low cost and lack of metabolites. Potential risks include a long half-life, drug interactions, and potential for QT prolongation at high doses. Prospective studies should be conducted to evaluate the role of methadone in CIPN pain management more comprehensively.

The Impact of Caregiving on the Association Between Infant Emotional Behavior and Resting State Neural Network Functional Topology.

The extent to which neural networks underlying emotional behavior in infancy serve as precursors of later behavioral and emotional problems is unclear. Even less is known about caregiving influences on these early brain-behavior relationships. To study brain-emotional behavior relationships in infants, we examined resting-state functional network metrics and infant emotional behavior in the context of early maternal caregiving. We assessed 46 3-month-old infants and their mothers from a community sample. Infants underwent functional MRI during sleep. Resting-state data were processed using graph theory techniques to examine specific nodal metrics as indicators of network functionality. Infant positive and negative emotional behaviors, and positive, negative and mental-state talk (MST) indices of maternal caregiving were coded independently from filmed interactions. Regression analyses tested associations among nodal metrics and infant emotionality, and the moderating effects of maternal behavior on these relationships. All results were FDR corrected at alpha = 0.05. While relationships between infant emotional behavior or maternal caregiving, and nodal metrics were weak, higher levels of maternal MST strengthened associations between infant positive emotionality and nodal metrics within prefrontal (p < 0.0001), and occipital (p < 0.0001) cortices more generally. Positive and negative aspects of maternal caregiving had little effect. Our findings suggest that maternal MST may play an important role in strengthening links between emotion regulation neural circuitry and early infant positive behavior. They also provide objective neural markers that could inform and monitor caregiving-based interventions designed to improve the health and well-being of vulnerable infants at-risk for behavioral and emotional problems.

Modified Edmonton Symptom Assessment System including constipation and sleep: validation in outpatients with cancer.

CONTEXT: The Edmonton Symptom Assessment System (ESAS) measures the severity of nine symptoms. Constipation and sleep disturbance are common in patients with cancer, but are not currently included in the ESAS. OBJECTIVES: To validate the numerical rating scale (NRS) versions of ESAS and its revised version (ESAS-r), with the additional symptoms of constipation and sleep (CS), and to assess patient preference for either version. METHODS: Outpatients with advanced cancer (N = 202) completed three assessments during a single clinic visit: ESAS-CS, and an added time window of "past 24 hours"; ESAS-r-CS, with a time window of "now" and symptom definitions; and the Memorial Symptom Assessment Scale (MSAS). Internal consistency was calculated using Cronbach's alpha. Paired t-tests compared ESAS-CS and ESAS-r-CS scores; these were correlated with MSAS using Spearman correlation coefficients. Test-retest reliability at 24 hours was assessed in 26 patients. RESULTS: ESAS-CS and ESAS-r-CS total scores correlated well with total MSAS (Spearman's rho 0.62 and 0.64, respectively). Correlation of individual symptoms with MSAS symptoms ranged from 0.54-0.80 for ESAS-CS and 0.52-0.74 for ESAS-r-CS. Although participants preferred the ESAS-r-CS format (42.8% vs. 18.6%) because of greater clarity and understandability, the "past 24 hours" time window (52.8%) was favored over "now" (21.3%). Shortness of breath and nausea correlated better for the "past 24 hours" time window (0.8 and 0.72 vs. 0.74 and 0.64 in ESAS-r-CS, respectively). The 24-hour test-retest of the ESAS-CS demonstrated acceptable reliability (intraclass correlation coefficient = 0.69). CONCLUSION: The ESAS-CS and ESAS-r-CS NRS versions are valid and reliable for measuring symptoms in this population of outpatients with advanced cancer. Although the ESAS-r-CS was preferred, patients favored the 24-hour time window of the ESAS-CS, which also may best characterize fluctuating symptoms.

The acceptability of humor between palliative care patients and health care providers.

BACKGROUND: Humor frequently occurs in palliative care environments; however, the acceptability of humor, particularly between patients and health care providers has not been previously examined. OBJECTIVES: To explore the importance and acceptability of humor to participants who are patients in a palliative care context, the study determines if demographics are correlated with the degree of acceptability, and examines the acceptance of humor by patients with advanced illness when interacting with nurses or physicians. METHODS: One hundred participants admitted to a palliative care unit or residential hospice were surveyed. Basic demographic data were collected, as well as responses on a five-point Likert scale to a variety of questions regarding the participants' attitudes about humor before and after their illness and the acceptability of humor in a palliative setting. Participants were also given the opportunity to comment freely on the topic of humor and the palliative experience. RESULTS: A large majority of participants valued humor highly both prior to (77%) and during (76%) their illness experience. Despite this valuation, the frequency of laughter in their daily lives diminished significantly as patients' illness progressed. Most participants remembered laughing with a nurse (87%) and a doctor (67%) in the week prior to the survey, and found humor with their doctors (75%) and nurses appropriate (88%). CONCLUSION: The vast majority of participants found humorous interactions with their health care providers acceptable and appropriate, and this may indicate a opportunity for enhanced and more effective end-of-life care in the future.

Simple prognostic model for patients with advanced cancer based on performance status.

PURPOSE: Providing survival estimates is important for decision making in oncology care. The purpose of this study was to provide survival estimates for outpatients with advanced cancer, using the Eastern Cooperative Oncology Group (ECOG), Palliative Performance Scale (PPS), and Karnofsky Performance Status (KPS) scales, and to compare their ability to predict survival. METHODS: ECOG, PPS, and KPS were completed by physicians for each new patient attending the Princess Margaret Cancer Centre outpatient Oncology Palliative Care Clinic (OPCC) from April 2007 to February 2010. Survival analysis was performed using the Kaplan-Meier method. The log-rank test for trend was employed to test for differences in survival curves for each level of performance status (PS), and the concordance index (C-statistic) was used to test the predictive discriminatory ability of each PS measure. RESULTS: Measures were completed for 1,655 patients. PS delineated survival well for all three scales according to the log-rank test for trend (P < .001). Survival was approximately halved for each worsening performance level. Median survival times, in days, for each ECOG level were: EGOG 0, 293; ECOG 1, 197; ECOG 2, 104; ECOG 3, 55; and ECOG 4, 25.5. Median survival times, in days, for PPS (and KPS) were: PPS/KPS 80-100, 221 (215); PPS/KPS 60 to 70, 115 (119); PPS/KPS 40 to 50, 51 (49); PPS/KPS 10 to 30, 22 (29). The C-statistic was similar for all three scales and ranged from 0.63 to 0.64. CONCLUSION: We present a simple tool that uses PS alone to prognosticate in advanced cancer, and has similar discriminatory ability to more complex models.

Addition of methadone to another opioid in the management of moderate to severe cancer pain: a case series.

BACKGROUND: Previous research has reported improved pain after adding methadone to another opioid, but did not quantify this benefit using a validated outcome measure. OBJECTIVE: To assess quantitatively the effectiveness of adding methadone to another opioid for moderate to severe cancer-related pain. DESIGN: All outpatients attending the Oncology Palliative Care Clinic from September 2010-September 2011, who had received methadone, were identified from pharmacy records. Inclusion criteria included: histological diagnosis of malignancy, age >18 years, taking regular opioids and Edmonton Symptom Assessment System (ESAS) pain score ≥ 4. MEASUREMENT: The primary outcome measure was a decrease in pain score of ≥ 2 points from methadone initiation to one-month follow-up (or closest available ESAS). RESULTS: Twenty patients were available for analysis, 16 of whom had neuropathic pain (80%). Eight patients (40%) had a decrease in pain score of ≥ 2 points at 1 month and a further 7 (35%) had a decrease of ≥ 2 points at the closest available time point. The mean pain score decreased from 7.7 +/- 1.8 to 5.2 +/- 2.4 from time of initiation to time of evaluation. The mean daily routine morphine equivalent, (excluding methadone), was 338 +/- 217.8 mg/day at initiation and 332 +/- 191 mg/day at evaluation; for methadone, mean doses at initiation and evaluation were 4.4 +/- 1.4 mg/day and 15.5 +/- 5.9 mg/day, respectively. Methadone was well tolerated in 17 patients (85%). CONCLUSIONS: The addition of methadone was associated with improved pain control for patients with moderate to severe pain on another opioid and appears to offer a safe, well-tolerated and practical alternative in this situation.

Impact of an oncology palliative care clinic on access to home care services.

Home care (HC) is important for patients with cancer as performance status declines. Our study of 1224 patients at a Canadian cancer center examined the impact of an oncology palliative care clinic (OPCC) on HC referral. The HC referral frequency was calculated before and after the first OPCC consultation, in total and according to performance status (Palliative Performance Scale, PPS). Characteristics associated with HC referral were investigated. After the first OPCC consultation, there was an increase in HC referral from 39% (477 of 1224; 49% of those with PPS ≤60) to 69% (841 of 1224; 88% of those with PPS ≤60). Factors independently associated with HC referral were poor PPS (P < .001) and older age (P = .003). Thus OPCC involvement resulted in markedly increased HC referrals, particularly for older patients with poor performance status.

Palliative care telephone consultation: who calls and what do they need to know?

BACKGROUND: Access to expertise in palliative management in areas not served by palliative care consultants is an ongoing challenge. This study examines a unique service offered in British Columbia: a 24-hour telephone hotline available to physicians, nurses, and pharmacists across the province. METHODS: Records of calls to the hotline over 4 years were collected. Call data included information on the caller, patient, and problem. The resulting database was analyzed for trends, including cross-tabulations to look for associations between call characteristics. RESULTS: Six hundred ninety-two calls were included. A large variety of topics were addressed in significant numbers, ranging from symptom control to ethical concerns. The primary reason for calls to the line was pain management, followed by gastrointestinal symptoms such as nausea, diarrhea, and bowel obstruction. Patients with cancer diagnoses dominated the call volume; lung, colon, breast, prostate, and pancreatic cancer were the most common specific diagnoses. The majority of calls, when analyzed by population, came from areas with significant rural populations. CONCLUSION: British Columbia's Palliative Care Hotline provides a valuable service that has been utilized province-wide with increasing frequency over the 6 years it has been in operation. It serves a variety of professionals and significant number of patients. Rural communities utilize the service with the most frequency, indicating the support needed in these communities. Similar services should be considered in other jurisdictions.

Healthy Buddies: a novel, peer-led health promotion program for the prevention of obesity and eating disorders in children in elementary school.

OBJECTIVE: We designed and tested a novel health promotion program for elementary schools that was based on peer teaching from older to younger schoolchildren ("Healthy Buddies"). SUBJECTS AND METHODS: This prospective pilot study compared the effect of our program (2-3 hours/week, 21 weeks) in 2 Canadian elementary schools (intervention: n = 232 children, the whole school implementing the program; control: n = 151). Older students (4th through 7th grade) were given direct instruction from 1 intervention teacher and were paired with younger students (kindergarten through 3rd grade) for the whole school year. Students in 4th through 7th grade then acted as teachers for their younger "buddies." All lessons included 3 components of healthy living: nutrition, physical activity, and healthy body image. The students first learned how to be positive buddies and learned the 3 components of a healthy life. Thereafter, they learned how to overcome challenges to living a healthy life. Outcome measures (intervention and control schools at the beginning and end of the school year) included validated questionnaires that assessed healthy-living knowledge, behavior and attitude, a 9-minute fitness run, self-competence, body satisfaction, disordered eating symptoms, and anthropometry (BMI, blood pressure, and heart rate). RESULTS: Compared with control students, both older and younger intervention students showed an increase in healthy-living knowledge, behavior, and attitude scores and a smaller increase in systolic blood pressure. BMI and weight increased less in the intervention students in 4th through 7th grade and height more in the intervention students in kindergarten through 3rd grade. CONCLUSIONS: Our student-led curriculum improved knowledge not only in older schoolchildren but also in their younger buddies. It also decreased weight velocity in the older students. Student-led teaching may be an efficient, easy-to-implement way of promoting a healthy lifestyle from kindergarten to 7th grade.
