Palliative care research – priorities and the way forward

Midazolam Indications and Dosing in Palliative Medicine: Results from a Multinational Survey

Despite sparse evidence and limited guidance on indications, use, and dosing, midazolam is widely used in palliative care. We aimed to describe and compare the use of midazolam in three different countries to improve clinical practice in palliative care. We performed an online survey among palliative care physicians in Norway, Denmark, and the United Kingdom (UK). The focus was indications, dosing, administration, and concomitant drugs. A web-based questionnaire was distributed to members of the respective national palliative medicine associations. The total response rate was 9.4%. Practices in the UK, Norway, and Denmark were overall similar regarding the indications of midazolam for anxiety, dyspnoea, and pain treatment in combination with opioids. However, physicians in the UK used a higher starting dose for anxiety, dyspnoea, and pain treatment compared to Norway and Denmark, as well as a higher maximum dose. Danish physicians preferred, to a higher degree, on-demand midazolam administration. Despite practice similarities in the UK, Norway, and Denmark, differences exist for midazolam dosing and administration in palliative medicine. We demonstrated a lack of consensus on how midazolam should be used in palliative care, setting the stage for future studies on the topic.

Health Care Providers' Attitudes and Beliefs on Providing Palliative Care to Patients in Bahrain: Findings From a Qualitative Study

CONTEXT

Present studies suggested that cultural and religious factors, as well as law and policy, may have impeded the advancement of palliative care in the Middle East. Little is known about health care providers' perceptions of palliative care and the barriers to its development in the Gulf Cooperation Council.

OBJECTIVES

To understand health care professionals' attitudes and beliefs regarding palliative care and highlight current practice barriers in Bahrain.

METHODS

Semistructured interviews with 16 health care providers (physicians and nurses) were conducted. Thematic analysis was then performed after interviews were transcribed verbatim.

RESULTS

Health care professionals perceived palliative care as a service only delivered to patients at the end of life. Palliative care was only offered to patients who have been diagnosed with cancer and had exhausted all curative treatments. Do-not-resuscitate orders and code status discussions are not currently practiced. Palliative care decisions are usually decided by patients' families. Middle Eastern culture, health care law and policy, conservative interpretations of Islam, and a lack of professional expertise were identified as barriers.

CONCLUSION

This study unveiled the perceptions of palliative care among health care professionals in a Gulf Cooperation Council country. Six major barriers that hindered palliative care practice were identified. Future health care policy in the region needs to address these barriers within the current health care system while taking culture, religion, and social factors into consideration.

Dysphagia Prevalence and Predictors in Cancers Outside the Head, Neck, and Upper Gastrointestinal Tract

CONTEXT

Dysphagia is usually associated with malignancies of the head, neck, and upper gastrointestinal tract but also occurs in those with tumors outside anatomic swallow regions. It can lead to aspiration pneumonia, malnutrition, reduced quality of life, and psychosocial distress. No studies have yet reliably described dysphagia prevalence in those with malignancies outside anatomic swallow regions.

OBJECTIVE

The objective of this study was to establish the prevalence and predictors of dysphagia in adults with solid malignancies outside the head, neck, and upper gastrointestinal tract.

METHODS

A cross-sectional, observational study using consecutive sampling was conducted. There were 385 participants (mean age 66 ± 12 years) with 21 different primary cancer sites from two acute hospitals and one hospice. Locoregional disease was present in 33%, metastatic in 67%. Dysphagia was screened by empirical questionnaire and confirmed through swallow evaluation. Demographic and clinical predictors were determined by univariate and multivariate binary regression.

RESULTS

Dysphagia occurred in 19% of those with malignancies outside anatomic swallow regions. Prevalence was 30% in palliative care and 32% in hospice care. Dysphagia was most strongly associated with cough, nausea, and worse performance status. It was also associated with lower quality of life and nutritional difficulties.

CONCLUSION

Dysphagia was common and usually undiagnosed before study participation. It occurred at all disease stages but coincided with functional decline. It may therefore represent a cancer frailty marker. Oncology and palliative care services should routinely screen for this symptom. Timely dysphagia identification and management may improve patient well-being and prevent adverse effects like aspiration pneumonia and weight loss.

Pilot testing of the first version of the European Association for Palliative Care basic dataset: A mixed methods study

BACKGROUND

Inadequate description of palliative care cancer patients in research studies often leads to results having limited generalizability. To standardize the description of the sample, the European Association for Palliative Care basic data set was developed, with 31 core demographic and disease-related variables.

AIM

To pilot test the data set to check acceptability, comprehensibility and feasibility.

DESIGN

International, multi-centre pilot study at nine study sites in five European countries, using mixed methods.

SETTING/PARTICIPANTS

Adult cancer patients and staff in palliative care units, hospices and home care.

RESULTS

In all, 191 patients (544 screened) and 190 health care personnel were included. Median time to fill in the patient form was 5 min and the health care personnel form was 7 min. Ethnicity was the most challenging item for patients and requires decisions at a national level about whether or how to include. Health care personnel found weight loss, principal diagnosis, additional diagnoses and stage of non-cancer diseases most difficult to respond to. Registration of diagnoses will be changed from International Statistical Classification of Diseases and Related Health Problems, 10th version code to a predefined list, while weight loss and stage of non-cancer diseases will be removed. The pilot study has led to rewording of items, improvement in response options and shortening of the data set to 29 items.

CONCLUSION

Pilot testing of the first version of the European Association for Palliative Care basic data set confirmed that patients and health care personnel understand the questions in a consistent manner and can answer within an acceptable timeframe. The pilot testing has led to improvement, and the new version is now subject to further testing.

Findings From a Thematic Synthesis of Key Messages From a Palliative Care Research Network: The KINDLE Project

BACKGROUND

Effective palliative care requires a strong evidence base to advance clinical practice and policy-making. Calls for more collaborative and strategic approaches to research have resulted in the development of research networks at national and wider regional levels.

AIM

The aim was to synthesize the learning arising from the activities of the Palliative Care Research Network from the island of Ireland, in order to identify the overarching messages from these activities. The ultimate aim is to promote the communication of these messages to practice.

DESIGN

The study developed a systematic search process influenced by Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, with analysis of data adopting a qualitative critical interpretative synthesis approach using thematic synthesis.

PARTICIPANTS

In total, 142 dissemination products were sourced from 22 associated projects, including peer-reviewed publications, conference presentations, reports, and web/social media posts.

RESULTS

The synthesis of dissemination products identified 4 key themes relating to palliative care research and practice: (1) addressing the needs of patients while recognizing the caregiver role, (2) equal access to connected services, (3) general and specific needs in palliative care research, and (4) challenges in palliative care research.

CONCLUSIONS

The key themes identified relate to challenges in both practice and research, highlighting the complexity of palliative care provision that aims to support both patients and carers, and research in this area. However, an important implication is the need for a broader approach to dissemination (beyond traditional academic activities) to ensure that research in palliative care is well placed to inform both practice and policy.

Better palliative care for people with a dementia: summary of interdisciplinary workshop highlighting current gaps and recommendations for future research

BACKGROUND

Dementia is the most common neurological disorder worldwide and is a life-limiting condition, but very often is not recognised as such. People with dementia, and their carers, have been shown to have palliative care needs equal in extent to those of cancer patients. However, many people with advanced dementia are not routinely being assessed to determine their palliative care needs, and it is not clear why this is so.

MAIN BODY

An interdisciplinary workshop on "Palliative Care in Neurodegeneration, with a focus on Dementia", was held in Cork, Ireland, in May 2016. The key aim of this workshop was to discuss the evidence base for palliative care for people with dementia, to identify 'gaps' for clinical research, and to make recommendations for interdisciplinary research practice. To lead the discussion throughout the day a multidisciplinary panel of expert speakers were brought together, including both researchers and clinicians from across Ireland and the UK. Targeted invitations were sent to attendees ensuring all key stakeholders were present to contribute to discussions. In total, 49 experts representing 17 different academic and practice settings, attended. Key topics for discussion were pre-selected based on previously identified research priorities (e.g. James Lind Alliance) and stakeholder input. Key discussion topics included: i. Advance Care Planning for people with Dementia; ii. Personhood in End-of-life Dementia care; iii. Topics in the care of advanced dementia at home. These topics were used as a starting point, and the ethos of the workshop was that the attendees could stimulate discussion and debate in any relevant area, not just the key topics, summarised under iv. Other priorities.

CONCLUSIONS

The care experienced by people with dementia and their families has the potential to be improved; palliative care frameworks may have much to offer in this endeavour. However, a solid evidence base is required to translate palliative care into practice in the context of dementia. This paper presents suggested research priorities as a starting point to build this evidence base. An interdisciplinary approach to research and priority setting is essential to develop actionable knowledge in this area.

The Edmonton Symptom Assessment System: Poor performance as screener for major depression in patients with incurable cancer

BACKGROUND

Depressive symptoms are prevalent in patients with advanced cancer, sometimes of a severity that fulfil the criteria for a major depressive episode.

AIM

The aim of this study was to investigate how the item on depression in the Edmonton Symptom Assessment System with a 0-10 Numerical Rating Scale performed as a screener for major depressive episode. A possible improved performance by adding the Edmonton Symptom Assessment System-Anxiety item was also examined.

DESIGN

An international cross-sectional study including patients with incurable cancer was conducted. The Edmonton Symptom Assessment System score was compared against major depressive episode as assessed by the Patient Health Questionnaire-9. Screening performance was examined by sensitivity, specificity and the kappa coefficient.

SETTING

Patients with incurable cancer (n = 969), median age 63 years and from eight nationalities provided report. Median Karnofsky Performance Status was 70. Median survival was 229 days (205-255 days).

RESULTS

Patient Health Questionnaire-9 major depressive episode was present in 133 of 969 patients (13.7%). Edmonton Symptom Assessment System-Depression screening ability for Patient Health Questionnaire-9 major depressive episode was limited. Area under the receiver operating characteristic curve was 0.71 (0.66-0.76). Valid detection or exclusion of Patient Health Questionnaire-9 major depressive episode could not be concluded at any Edmonton Symptom Assessment System-Depression cut-off; by the cut-off Numerical Rating Scale ⩾ 2, sensitivity was 0.69 and specificity was 0.60. By the cut-off Numerical Rating Scale ⩾ 4, sensitivity was 0.51 and specificity was 0.82. Combined mean ratings by Edmonton Symptom Assessment System-Depression and Edmonton Symptom Assessment System-Anxiety revealed similar limited screening ability.

CONCLUSION

The depression and anxiety items of the Edmonton Symptom Assessment System, a frequently used assessment tool in palliative care settings, seem to measure a construct other than major depressive episode as assessed by the Patient Health Questionnaire-9 instrument.

Reality of evidence-based practice in palliative care

There has been a paradigm shift in medicine away from tradition, anecdote and theoretical reasoning from the basic sciences towards evidence-based medicine (EBM). In palliative care however, statistically significant benefits may be marginal and may not be related to clinical meaningfulness. The typical treatment vs. placebo comparison necessitated by ‘gold standard’ randomised controlled trials (RCTs) is not necessarily applicable. The complex multimorbidity of end of life care involves considerations of the patient’s physical, psychological, social and spiritual needs. In addition, the field of palliative care covers a heterogeneous group of chronic and incurable diseases no longer limited to cancer. Adequate sample sizes can be difficult to achieve, reducing the power of studies and high attrition rates can result in inadequate follow up periods. This review uses examples of the management of cancer-related fatigue and death rattle (noisy breathing) to demonstrate the current state of EBM in palliative care. The future of EBM in palliative care needs to be as diverse as the patients who ultimately derive benefit. Non-RCT methodologies of equivalent quality, validity and size conducted by collaborative research networks using a ‘mixed methods approach’ are likely to pose the correct clinical questions and derive evidence-based yet clinically relevant outcomes.

Establishment and preliminary outcomes of a palliative care research network

Objective:

The difficulties in conducting palliative care research have been widely acknowledged. In order to generate the evidence needed to underpin palliative care provision, collaborative research is considered essential. Prior to formalizing the development of a research network for the state of Victoria, Australia, a preliminary study was undertaken to ascertain interest and recommendations for the design of such a collaboration.

Method:

Three data-collection strategies were used: a cross-sectional questionnaire, interviews, and workshops. The questionnaire was completed by multidisciplinary palliative care specialists from across the state (n = 61); interviews were conducted with senior clinicians and academics (n = 21) followed by two stakeholder workshops (n = 29). The questionnaire was constructed specifically for this study, measuring involvement of and perceptions of palliative care research.

Results:

Both the interview and the questionnaire data demonstrated strong support for a palliative care research network and aided in establishing a research agenda. The stakeholder workshops assisted with strategies for the formation of the Palliative Care Research Network Victoria (PCRNV) and guided the development of the mission and strategic plan.

Significance of results:

The research and efforts to date to establish the PCRNV are encouraging and provide optimism for the evolution of palliative care research in Australia. The international implications are highlighted.

An examination of the research priorities for a hospice service in New Zealand: A Delphi study

Objectives:

Palliative care research is relatively diverse and prioritizing research in this field is dependent on multiple factors such as complex ethical decisions in designing and conducting the research; access to participants who may be deemed “vulnerable” and an increasingly medically focused approach to care. The aim of this study was to inform organizational decision-making and policy development regarding future research priorities for a hospice service in New Zealand.

Methods:

A modified three-round Delphi technique was employed. Participants were drawn from one dedicated specialist palliative care service that delivers care in the community, day-care, hospice inpatient, aged residential care, and acute hospital palliative care service. A purposive sample included palliative care staff (n = 10, 18, 9, for rounds 1–3, respectively) volunteers (n = 10, 12, 11); and patients and family carers (n = 6, 8, for rounds 1 and 2). Patients and family carers were not involved in the third round.

Results:

At final ranking of six research themes encompassing 23 research topics were identified by staff and volunteers. These were: symptom management; aged care; education; community; patient and family; and bereavement support and young people. Patients and family carers agreed on four themes, made up of 10 research topics. These were: decision-making, bereavement and loss, symptom management; and recognition of need and response of service.

Significance of results:

The study generated a rich set of research themes and specific research topics. The perspectives of staff and volunteers are significantly different from those of patients and family members, in spite of the recognition by all concerned that palliative care services work within a philosophy of patient-centered care. Open discussion of ideas has the potential to engage both staff and patients and carers in quality improvement initiatives, and to reinforce the value of research for patient care.

Improving the evidence base in palliative care to inform practice and policy: thinking outside the box

The adoption of evidence-based hierarchies and research methods from other disciplines may not completely translate to complex palliative care settings. The heterogeneity of the palliative care population, complexity of clinical presentations, and fluctuating health states present significant research challenges. The aim of this narrative review was to explore the debate about the use of current evidence-based approaches for conducting research, such as randomized controlled trials and other study designs, in palliative care, and more specifically to (1) describe key myths about palliative care research; (2) highlight substantive challenges of conducting palliative care research, using case illustrations; and (3) propose specific strategies to address some of these challenges. Myths about research in palliative care revolve around evidence hierarchies, sample heterogeneity, random assignment, participant burden, and measurement issues. Challenges arise because of the complex physical, psychological, existential, and spiritual problems faced by patients, families, and service providers. These challenges can be organized according to six general domains: patient, system/organization, context/setting, study design, research team, and ethics. A number of approaches for dealing with challenges in conducting research fall into five separate domains: study design, sampling, conceptual, statistical, and measures and outcomes. Although randomized controlled trials have their place whenever possible, alternative designs may offer more feasible research protocols that can be successfully implemented in palliative care. Therefore, this article highlights "outside the box" approaches that would benefit both clinicians and researchers in the palliative care field. Ultimately, the selection of research designs is dependent on a clearly articulated research question, which drives the research process.

The European Association for Palliative Care basic dataset to describe a palliative care cancer population: Results from an international Delphi process

BACKGROUND

One of the barriers identified in palliative care research is the lack of common criteria to describe the population.

AIM

The aim of this Delphi process was to obtain consensus on a basic set of core variables to describe or classify a palliative care cancer population.

DESIGN AND SETTING

This was a five-step international Delphi exercise. A total of 117 experts were invited to participate. Based on a literature review and analyses of existing minimum datasets for national databases, a list of 18 proposed variables was presented in the first Delphi round. The two first rounds focused on which variables to include, and several new variables were proposed. The three last Delphi rounds focused on how the agreed variables should be recorded. Consensus was defined as at least 70% agreement.

RESULTS

A total of 64 experts from 30 countries participated. High consensus was reached on 31 variables, divided between a 'patient form' - date of birth, gender, living situation, education, ethnicity and 12 symptoms - and a 'health-care personnel form' - patient's date of birth, principal diagnosis, date of the principal diagnosis, stage of the cancer disease, site of metastases, present anticancer treatment, main additional diagnoses, stage of the additional diagnoses, medication, weight loss, performance status, cognitive impairment, place of care and provision of care. It was more difficult to agree upon how to record the variables, but consensus was reached on all except ethnicity, vomiting and weight loss.

CONCLUSION

Consensus was reached on a set of core variables and how they should be recorded.

How are palliative care cancer populations characterized in randomized controlled trials? A literature review

CONTEXT

The difficulties in defining a palliative care patient accentuate the need to provide stringent descriptions of the patient population in palliative care research.

OBJECTIVES

To conduct a systematic literature review with the aim of identifying which key variables have been used to describe adult palliative care cancer populations in randomized controlled trials (RCTs).

METHODS

The data sources used were MEDLINE (1950 to January 25, 2010) and Embase (1980 to January 25, 2010), limited to RCTs in adult cancer patients with incurable disease. Forty-three variables were systematically extracted from the eligible articles.

RESULTS

The review includes 336 articles reporting RCTs in palliative care cancer patients. Age (98%), gender (90%), cancer diagnosis (89%), performance status (45%), and survival (45%) were the most frequently reported variables. A large number of other variables were much less frequently reported.

CONCLUSION

A substantial variation exists in how palliative care cancer populations are described in RCTs. Few variables are consistently registered and reported. There is a clear need to standardize the reporting. The results from this work will serve as the basis for an international Delphi process with the aim of reaching consensus on a minimum set of descriptors to characterize a palliative care cancer population.

Palliative care research in Africa: consensus building for a prioritized agenda

CONTEXT

Palliative care research in Africa is in its relative infancy, with dedicated financial support extremely limited. Therefore, setting research priorities to optimize use of limited resources is imperative.

OBJECTIVES

To develop a prioritized research agenda for palliative care in Africa.

METHODS

We used a two-stage process involving palliative care professionals and researchers: 1) generation of an initial topic list at a consultative workshop of experts and 2) prioritization of that list using a consensus development process, the nominal group technique.

RESULTS

Phase 1: 41 topics were generated across five groups, with several topics nominated in more than one group. Phase 2: 16 topics and three broad thematic areas were identified. The two most prioritized topics within each of the three themes were the following: Theme 1: patient, family, and volunteers-1) care outcomes and the impact of palliative care as perceived by patients and caregivers and 2) palliative care needs of children; Theme 2: health providers-1) impact of palliative care training on care and practice and 2) integration of palliative care and antiretroviral therapy services; and Theme 3: health systems-1) palliative care needs assessments at the micro-, meso-, and macro-levels and 2) integration of palliative care into health systems and educational curricula.

CONCLUSION

Consensus-based palliative care topics determined by the study can assist researchers in optimizing limited research capacities by focusing on these prioritized areas. Subsequent to the identification and publication of the research agenda, concrete steps will be undertaken by the African Palliative Care Research Network and other partners to help implement it.

Training and career development in palliative care and end-of-life research: opportunities for development in the U.S

There has been a dramatic increase in attention to the field of palliative care and end-of-life (PCEOL) research over the past 20 years. This increase is particularly notable in the development of palliative care clinical and educational programs. However, there remain important shortcomings in the evidence base to ensure access to and delivery of effective palliative care for patients with life-limiting illness and their families. Development of this evidence base will require that we train the next generation of researchers to focus on issues in PCEOL. The purpose of this article was to explore the current status of the recruitment, training, and retention of future investigators in PCEOL research in the U.S. and propose recommendations to move us forward. Some key contextual issues for developing and supporting this research workforce are articulated, along with timely and important research areas that will need to be addressed during research training and career development. We provide targeted key recommendations to facilitate the nurturing and support of the future research workforce that is needed to ensure the development and implementation of the science necessary for providing high-quality, evidence-based palliative care to all who need and desire it.

Palliative care research on the island of Ireland over the last decade: a systematic review and thematic analysis of peer reviewed publications

Background

As palliative care research continues to expand across Europe, and the world, questions exist about the nature and type of research undertaken in addition to the research priorities for the future. This systematic review, which is the first stage of a larger scale study to identify the research priorities for palliative care on the island of Ireland, examined palliative care research conducted on the island over the last decade.

Methods

A comprehensive search strategy was implemented and strict eligibility criteria were applied in order to identify relevant peer-reviewed journal articles. Inclusion criteria were all of the palliative care studies undertaken on the island of Ireland and published between January 2002 and May 2012. These were assessed in relation to year, setting, sample size, research methodology, and relevant findings.

Results

412 publications were identified for screening and their abstracts obtained. After eliminating articles that did not meet the inclusion criteria, 151 remained for further analysis. A thematic analysis of 128 studies published between 2006 and 2012 revealed eight core themes: (1) specific groups/populations; (2) services and settings; (3) management of symptoms (physical, psychological, social); (4) bereavement; (5) communication and education; (6) death and dying; (7) spirituality; and (8) complementary and alternative medicine/intervention (CAM). There was an upward trend in the number of publications in palliative care research over the last ten years with over 72% of studies being published within the previous four years. A slightly higher number of studies were quantitative in nature (surveys, questionnaires, standardised assessments) followed by qualitative (individual and focus group interviews, case studies, documentary analysis and retrospective case note reviews), mixed methods, and systematic reviews.

Conclusions

Whilst there has been a welcome growth in palliative care research across Ireland, this has largely been needs-based and small scale studies. In contrast, international researchers and decision makers recommend the need for more outcomes focused multidisciplinary research. An examination of palliative care research is an essential first step in seeking to develop future priority areas for further research, highlighting opportunities for future collaboration both nationally and internationally.

Barriers to research in palliative care in France

PURPOSE

Palliative care (PC) needs expansion of its research capacity to improve the quality of care. This is particularly true for France that contributed less than 2% of all European PC research publications. We conducted a survey to assess the barriers French healthcare professionals (HCPs) involved in PC research had to face.

METHODS

We surveyed all 420 PC departments registered in the French National Association for Palliative Care (SFAP) database using a previously used questionnaire. We documented the ethical limitations, time constraints, financial resources, patient issues and methodological issues related to PC research.

RESULTS

We obtained 382 responses. Ninety-two (24.1%) HCPs were involved in a research project during the last 5 years. In univariate results, predictors of being involved in PC research were men (p=0.004), physician (p=0.022), working at a university hospital (p<0.001). There was a trend towards working in a PC unit (p=0.052). The main barriers to participating in PC research were lack of time (80.1%) and patient issues (47.4%). Lack of methodological support (33.0%) and financial limitations (30.4%) were also reported as major barriers.

CONCLUSIONS

There is a consensus that PC research and publication in the English language for peer-reviewed journals must be expanded in France but at this stage, clinical teams still lack specific funding and appropriate support. More research is needed to confirm our results and to determine the best ways to develop PC research capacity in France.

A pan-European survey of research in end-of-life cancer care

Background

To date, there is no coordinated strategy for end-of-life (EOL) cancer care research in Europe. The PRISMA (Reflecting the Positive Diversities of European Priorities for Research and Measurement in End-of-life Care) project is aiming to develop a programme integrating research and measurement in EOL care. This survey aimed to map and describe present EOL cancer care research in Europe and to identify priorities and barriers.

Material and methods

A questionnaire of 62 questions was developed and 201 researchers in 41 European countries were invited to complete it online in May 2009. An open invitation to participate was posted on the internet.

Results

Invited contacts in 36 countries sent 127 replies; eight additional responses came through websites. A total of 127 responses were eligible for analysis. Respondents were 69 male and 58 female, mean age 49 (28–74) years; 85% of the scientific team leaders were physicians. Seventy-one of 127 research groups were located in a teaching hospital or cancer centre. Forty-five percent of the groups had only one to five members and 28% six to ten members. Sixty-three of 92 groups reported specific funding for EOL care research. Seventy-five percent of the groups had published papers in journals with impact factor ≤5 in the last 3 years; 8% had published in journals with impact factor >10. Forty-four out of 90 groups reported at least one completed Ph.D. in the last 3 years. The most frequently reported active research areas were pain, assessment and measurement tools, and last days of life and quality of death. Very similar areas—last days of life and quality of death, pain, fatigue and cachexia, and assessment and measurement tools—were ranked as the most important research priorities. The most important research barriers were lack of funding, lack of time, and insufficient knowledge/expertise.

Conclusions

Most research groups in EOL care are small. The few large groups (14%) had almost half of the reported publications, and more than half of the current Ph.D. students. There is a lack of a common strategy and coordination in EOL cancer care research and a great need for international collaboration.

Clinical priorities, barriers and solutions in end-of-life cancer care research across Europe. Report from a workshop

AIM

The PRISMA project is aiming to co-ordinate research priorities, measurement and practice in end-of-life (EOL) care in Europe. As part of PRISMA we undertook a questionnaire survey and a subsequent workshop to (1) identify clinical priorities for EOL care research in Europe and propose a future research agenda and (2) identify barriers to EOL care research, and possibilities and solutions to improve the research.

METHODS

Thirty participants selected among the principally medical survey responders from 25 European countries attended. Twenty-six answered a preparatory pre-workshop questionnaire based on the survey results. Group work was a main part of the workshop.

RESULTS

Consensus was reached on the following priorities for EOL cancer care research in Europe: symptomatology, issues related to care of the dying, and policy and organisation of services. Methodology was regarded important in all areas, including assessment/measurement and classification. Symptom research should particularly emphasise pain, fatigue, cachexia, delirium and breathlessness. Research should move from descriptive to interventional studies. The lack of consensus on definitions and outcomes was identified as a substantial research barrier. Other barriers were related to capacity and funding, environment and culture and knowledge transfer and dissemination. These areas are interrelated and should not be addressed in isolation.

CONCLUSION

Consensus was obtained on priority areas and research nature for EOL care research in the next years, and a model for addressing barriers was developed.

[General practitioners' guideline for palliative care. A survey of guideline acceptance in quality circles of primary medical care]

PURPOSE

The implementation of the general practitioners' (GPs) guideline for palliative care released in 2007 with consent of the developing group was accompanied by an anonymous and voluntary survey designed to assess acceptance and feasibility of the recommendations. 60 quality circles of the GP-based care program in Hesse which are run by the PMV research group were used for guideline implementation.

MATERIAL AND METHODS

The quality of the palliative care quality circle meeting itself was checked with a standardized questionnaire (feedback, n = 473 of 515 participating GPs). After several weeks, the follow-up questioning on acceptance of the corresponding guideline was performed (n = 391 of 440 attendees) using twelve items to evaluate the guideline recommendations. The closed questions were appraised employing a Likert scale and the open questions after classifying the free text in categories.

RESULTS

96% of the respondents considered palliative medicine to be important in daily routine. The majority agreed with form and content of this CME meeting (feedback, response rate 91%). The complexity, handling, and practical relevance of the guideline were evaluated positively (response rate 88%). 82% of GPs reported that they would recommend the guideline to colleagues. Specific, practical guideline recommendations on (non)pharmacological strategies in treating dyspnea, on reducing xerostomia and on comedication in the case of opioid treatment were confirmed by 80-94% of the participants, and 75-92% rated these recommendations as practical.

CONCLUSION

The relevance of palliative care in daily routine was shown by the responses evaluating the quality circle session. The grade of acceptance of the guideline is comparable to the other GPs' guidelines with focus on pharmacotherapy. 10-13% of the respondents were not able to judge the relevance nor the practicability of selected recommendations. Future implementation should therefore consider attitude and experience with palliative care. To date, the questionnaires have not been designed to evaluate individual adherence to palliative care guideline.

Disparities in the contribution of low- and middle-income countries to palliative care research

CONTEXT

Important aspects of the palliative care needs of patients from low- and middle-income countries (LMIC) are largely unexplored. About 44 million of the 56 million annual deaths worldwide occur in developing countries, and it is estimated that more than 33 million of those concerned would benefit from palliative care. In this context, the understanding of specific social and cultural needs is fundamental to the development of appropriate health policy and clinical practice concerning palliative and end-of-life care.

OBJECTIVES

This study aims to answer the question: what are the contributions, in terms of generation of knowledge, of LMIC to the published palliative care literature?

METHODS

A bibliometric analysis was conducted in Medline and EMBASE (to June 2008). Articles were included when either the first author (institutional affiliation or contact address) or the data collection was derived from LMIC, as defined by criteria of the World Bank. Excluded were articles done in migrant and non-palliative care populations.

RESULTS

The literature search resulted in 845 references. In total, 245 articles coming from LMIC were identified, being published by 34 LMIC (27.3% of LMIC). The first publications appeared in 1982. The study shows a rather modest contribution of publications from LMIC. However, the volume of publications within LMIC is distributed unequally: upper-middle-income countries published almost half of the articles (46.9%), whereas only 11% of the publications came from low-income countries. In contrast, 104 LMIC (72.7% of LMIC) do not have any registered publications. Surprisingly, 25% of the articles with data from LMIC have been done and published by high-income countries. Reasons for the underrepresentation, as well a possible correction of this imbalance, are discussed.

CONCLUSION

Palliative care research should be a priority in LMIC, where many patients could benefit tremendously from it, and publication of findings in these countries should be encouraged.
