How to increase public participation in advance care planning: findings from a World Café to elicit community group perspectives.

Background: In 2014, Alberta, Canada broke new ground in having the first provincial healthcare policy and procedure for advance care planning (ACP), the process of communicating and documenting a person's future healthcare preferences. However, to date public participation and awareness of ACP remains limited. The aim of this initiative was to elicit community group perspectives on how to help people learn about and participate in ACP.

Understanding advance care planning within the South Asian community.

Background: Advance care planning (ACP) is a process of reflection on and communication of a person's future health-care preferences. Evidence suggests visible minorities engage less in ACP. The South Asian ethnic group is the largest visible minority group in Canada, and information is needed to understand how ACP is perceived and how best to approach ACP within this diverse community.

Readiness to participate in advance care planning: A qualitative study of renal failure patients, families and healthcare providers.

Objectives Advance care planning is the process by which people reflect upon their wishes and values for healthcare, discuss their choices with family and friends and document their wishes. Readiness represents a key predictor of advance care planning participation; however, the evidence for addressing readiness is scarce within the renal failure context. Our objectives were to assess readiness for advance care planning and barriers and facilitators to advance care planning uptake in a renal context.

How healthcare systems evaluate their advance care planning initiatives: Results from a systematic review.

Background: Advance care planning initiatives are being implemented across healthcare systems around the world, but how best to evaluate their implementation is unknown.

Aim: To identify gaps and/or redundancies in current evaluative strategies to help healthcare systems develop future evaluative frameworks for ACP.

Design: Systematic review.

Development of a rural palliative care program in the Calgary Zone of Alberta Health Services.

Specialized rural models of palliative care are greatly needed to address the challenges rural communities face in providing palliative care services and to ensure that their unique strengths and needs are considered. In late 2005, a Rural Palliative Care Program was developed to support primary care providers in delivering palliative care to patients in rural communities outside of Calgary, Alberta, Canada. The program was grounded in the needs of individual communities, incorporated integral roles for local champions, and adopted pre-existing, accepted rural structures and processes.

Formal feasibility studies in palliative care: why they are important and how to conduct them.

The concept of clinical trial feasibility is of great interest to the community of palliative care researchers, clinicians, and granting agencies. Significant allocation of resources is required in the form of funding, time, intellect, and motivation to carry out clinical research, and understandably, clinical investigators, institutions, and granting agencies are disappointed when funded trials are unsuccessfully conducted. We argue that for many trials conducted in palliative care, the feasibility of conducting the proposed trial should be formally explored before implementation.

Effectiveness of knowledge translation interventions to improve cancer pain management.

Context: Cancer pain is prevalent, yet patients do not receive best care despite widely available evidence. Although national cancer control policies call for education, effectiveness of such programs is unclear and best practices are not well defined.

Objectives: To examine existing evidence on whether knowledge translation (KT) interventions targeting health care providers, patients, and caregivers improve cancer pain outcomes.

Design and implementation of an online course on research methods in palliative care: lessons learned.

Background: Research capacity in palliative and end-of-life care is less than some other fields of medicine where there is a longer track record of biomedical research. Palliative medicine clinicians often receive little or no formal research training during their postgraduate education; hence, education efforts may prove pivotal to increasing palliative care research capacity. To that end, our group established a national online training program on palliative care research methodologies, called Foundations of Palliative Care Research.

A patient-completed and optically read data acquisition system for clinical trials.

Data collection and management within multicentre clinical trials can be challenging. We describe an adaptation of Teleform® technology to enable data recording by patients and their families on teleforms faxed and optically read directly into an electronic database, eliminating the need for case report forms. Preliminary results from a modest study sample size support the use of optically read forms for data collection by patients and their families, requiring only a pen, paper, and fax machine at participating sites.

Can the global uptake of palliative care innovations be improved? Insights from a bibliometric analysis of the Edmonton Symptom Assessment System.

Clinical research is undertaken to improve care for palliative patients, but little is known about how to support the broad uptake of resultant innovations. The objectives of this paper are to: (1) explore the uptake of the Edmonton Symptom Assessment System throughout the global palliative care community through the lens of a bibliometric review - a research method that maps out the journey of new knowledge uptake by evaluating where key articles are cited in published literature; (2) construct hypotheses on attributes of the global community of palliative care learners; and (3) make inferences on approaches that could improve knowledge transfer. While preliminary, results of the study suggest several specific approaches that could support widespread uptake of innovations in palliative care: targeting publication in high impact, international journals; explicitly focusing on how the innovation is applied to best practice; encouraging additional research to expand on early studies; consciously targeting key professional groups and organizations to promote discussion in the grey literature; and early translation and promotion within multiple languages.

Assessment of study quality for systematic reviews: a comparison of the Cochrane Collaboration Risk of Bias Tool and the Effective Public Health Practice Project Quality Assessment Tool: methodological research.

Background: The Cochrane Collaboration is strongly encouraging the use of a newly developed tool, the Cochrane Collaboration Risk of Bias Tool (CCRBT), for all review groups. However, the psychometric properties of this tool to date have yet to be described. Thus, the objective of this study was to add information about psychometric properties of the CCRBT including inter-rater reliability and concurrent validity, in comparison with the Effective Public Health Practice Project Quality Assessment Tool (EPHPP).

A formal feasibility study of sublingual methadone for breakthrough cancer pain.

We conducted a feasibility study of sublingual methadone for breakthrough cancer pain, to determine whether a larger, randomized trial was warranted, and to identify a study design that would be likely to succeed. From approximately 1930 patients in the initial pool, nine patients were enrolled. Five patients completed the study, generating data on 83 discrete episodes of breakthrough cancer pain at optimal dose.

Clinical trials focusing on cancer pain educational interventions: core components to include during planning and reporting.

Context: Robust recommendations on the reporting of methods and results of clinical trials such as therapeutic intervention trials are widely used, such as the Consolidated Standards of Reporting Trials (CONSORT) recommendation. There has not been agreement on analogous publication standards for educational intervention trials, making interpretation of educational intervention studies difficult.

Objectives: The purpose of this report is to describe common deficiencies in reporting of educational intervention trials for cancer pain control, and to offer suggestions for authors to consider as they plan their studies, and report and publish research findings for educational interventions that use randomized controlled trials and other educational trial methodologies.

A randomized controlled crossover trial of the effect of ginseng consumption on the immune response to moderate exercise in healthy sedentary men.

Ginseng is a popular herbal remedy that is reputed to increase resistance to stress and improve immune function. Regular exercise results in acute physiologic stress that affects the immune response. This study was conducted to investigate the effects of daily consumption of a standardized ginsenoside-containing North American ginseng (Panax quinquefolius) extract on immune function before, during, and after a moderate-exercise protocol in healthy sedentary men.

The potential for treatment with dietary long-chain polyunsaturated n-3 fatty acids during chemotherapy.

Dietary intake of long-chain omega-3 (or n-3) polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) can affect numerous processes in the body, including cardiovascular, neurological and immune functions, as well as cancer. Studies on human cancer cell lines, animal models and preliminary trials with human subjects suggest that administration of EPA and DHA, found naturally in our diet in fatty fish, can alter toxicities and/or activity of many drugs used to treat cancer. Multiple mechanisms are proposed to explain how n-3 PUFA modulate the tumor cell response to chemotherapeutic drugs.

Effect of CVT-E002 (COLD-fX) versus a ginsenoside extract on systemic and gut-associated immune function.

CVT-E002 (sold commercially as COLD-fX) is a patented, polysaccharide-rich extract of North American ginseng (Panax quinquefolium) with purported beneficial effects on influenza and the common cold, although its mechanism of action is largely unknown. This study was conducted to determine the effects of feeding CVT-E002 versus a ginsenoside-containing extract on systemic and gut-associated immune function. For 7 days, male weanling Sprague-Dawley rats (n=10/group) were fed one of four diets: control, low CVT-E002 (450 mg/kg), high CVT-E002 (900 mg/kg), or ginsenoside (450 mg/kg).

Applying the Delphi process to palliative care tool development: lessons learned.

Background: The Delphi technique is an effective method for collecting and synthesizing informed opinions on a highly focused task, from a diverse group of experts who have specialized knowledge in an area of interest. This method has been successfully applied to palliative care research but not commonly to palliative care tool development. The Delphi technique has recently been employed in the development of two palliative pain assessment tools: the Edmonton Classification System for Cancer Pain (ECS-CP) and the Alberta Breakthrough Pain Assessment Tool for Research (ABPAT-R).
