Processes of consent in research for adults with impaired mental capacity nearing the end of life: systematic review and transparent expert consultation (MORECare_Capacity statement)

BACKGROUND

Involving adults lacking capacity (ALC) in research on end of life care (EoLC) or serious illness is important, but often omitted. We aimed to develop evidence-based guidance on how best to include individuals with impaired capacity nearing the end of life in research, by identifying the challenges and solutions for processes of consent across the capacity spectrum.

METHODS

Methods Of Researching End of Life Care_Capacity (MORECare_C) furthers the MORECare statement on research evaluating EoLC. We used simultaneous methods of systematic review and transparent expert consultation (TEC). The systematic review involved four electronic databases searches. The eligibility criteria identified studies involving adults with serious illness and impaired capacity, and methods for recruitment in research, implementing the research methods, and exploring public attitudes. The TEC involved stakeholder consultation to discuss and generate recommendations, and a Delphi survey and an expert 'think-tank' to explore consensus. We narratively synthesised the literature mapping processes of consent with recruitment outcomes, solutions, and challenges. We explored recommendation consensus using descriptive statistics. Synthesis of all the findings informed the guidance statement.

RESULTS

Of the 5539 articles identified, 91 met eligibility. The studies encompassed people with dementia (27%) and in palliative care (18%). Seventy-five percent used observational designs. Studies on research methods (37 studies) focused on processes of proxy decision-making, advance consent, and deferred consent. Studies implementing research methods (30 studies) demonstrated the role of family members as both proxy decision-makers and supporting decision-making for the person with impaired capacity. The TEC involved 43 participants who generated 29 recommendations, with consensus that indicated. Key areas were the timeliness of the consent process and maximising an individual's decisional capacity. The think-tank (n = 19) refined equivocal recommendations including supporting proxy decision-makers, training practitioners, and incorporating legislative frameworks.

CONCLUSIONS

The MORECare_C statement details 20 solutions to recruit ALC nearing the EoL in research. The statement provides much needed guidance to enrol individuals with serious illness in research. Key is involving family members early and designing study procedures to accommodate variable and changeable levels of capacity. The statement demonstrates the ethical imperative and processes of recruiting adults across the capacity spectrum in varying populations and settings.

Emergency department-initiated palliative care for advanced cancer patients: protocol for a pilot randomized controlled trial

Background

For patients with advanced cancer, visits to the emergency department (ED) are common. Such patients present to the ED with a specific profile of palliative care needs, including burdensome symptoms such as pain, dyspnea, or vomiting that cannot be controlled in other settings and a lack of well-defined goals of care. The goals of this study are: i) to test the feasibility of recruiting, enrolling, and randomizing patients with serious illness in the ED; and ii) to evaluate the impact of ED-initiated palliative care on health care utilization, quality of life, and survival.

Methods/Design

This is a protocol for a single center parallel, two-arm randomized controlled trial in ED patients with metastatic solid tumors comparing ED-initiated palliative care referral to a control group receiving usual care. We plan to enroll 125 to 150 ED-advanced cancer patients at Mount Sinai Hospital in New York, USA, who meet the following criteria: i) pass a brief cognitive screen; ii) speak fluent English or Spanish; and iii) have never been seen by palliative care. We will use balanced block randomization in groups of 50 to assign patients to the intervention or control group after completion of a baseline questionnaire. All research staff performing assessment or analysis will be blinded to patient assignment. We will measure the impact of the palliative care intervention on the following outcomes: i) timing and rate of palliative care consultation; ii) quality of life and depression at 12 weeks, measured using the FACT-G and PHQ-9; iii) health care utilization; and iv) length of survival. The primary analysis will be based on intention-to-treat.

Discussion

This pilot randomized controlled trial will test the feasibility of recruiting, enrolling, and randomizing patients with advanced cancer in the ED, and provide a preliminary estimate of the impact of palliative care referral on health care utilization, quality of life, and survival.

'Best practice' in developing and evaluating palliative and end-of-life care services: a meta-synthesis of research methods for the MORECare project

BACKGROUND

Improved and cost-effective palliative and end-of-life care is an international policy imperative. Developments are impeded by a weak and often inconsistent evidence base.

AIM

To examine the main methodological challenges and limitations to developing and evaluating palliative and end-of-life care services and requirements to further this field of research.

DESIGN

A meta-synthesis to systematically appraise the evidence from systematic reviews on the research methods used in studies evaluating the effectiveness of palliative care services for patients with advanced illness and/or carers meeting inclusion and quality criteria. We extracted data from the reviews on the methodological issues reported on the included studies into Excel spreadsheets and generated textual descriptions coded and analysed in NVivo.

DATA SOURCES

Six electronic databases, reference chaining and expert advice.

RESULTS

In total, 27 systematic reviews were included on the effectiveness of palliative care services for patients with cancer (n = 6), advanced illness (n = 10) or mixed populations (n = 11) across care settings. Main methodological challenges were implementation as a continuum, active precise recruitment, addressing randomisation and economic evaluation beyond cost savings.

CONCLUSIONS

The complexity of delivering and evaluating palliative and end-of-life care services requires the accumulation of knowledge from multiple sources to understand the active components of an intervention to deliver patient benefit and examine the evaluation methods to detect change and reveal processes prior to a definitive trial. The implementation of evidence into practice should form a continuum throughout the evaluation stages to reveal understanding on the process of intervention delivery, the context and the intended outcome(s).

Designing and conducting randomized controlled trials in palliative care: A summary of discussions from the 2010 clinical research forum of the Australian Palliative Care Clinical Studies Collaborative

Rigorous clinical research in palliative care is challenging but achievable. Trial participants are likely to have deteriorating performance status, co-morbidities and progressive disease. It is difficult to recruit patients, and attrition unrelated to the intervention being trialled is high. The aim of this paper is to highlight practical considerations from a forum held to discuss these issues by active palliative care clinical researchers. To date, the Australian Palliative Care Clinical Studies Collaborative (PaCCSC) has randomized more than 500 participants across 12 sites in 8 Phase III studies. Insights from the 2010 clinical research forum of the PaCCSC are reported. All active Australian researchers in palliative care were invited to present their current research and address three specific questions: (1) What has worked well? (2) What didn't work well? and (3) How should the research be done differently next time? Fourteen studies were presented, including six double-blind, randomized, controlled, multi-site trials run by the PaCCSC. Key recommendations are reported, including guidance on design; methodologies; and strategies for maximizing recruitment and retention. These recommendations will help to inform future trial design and conduct in palliative care.

Palliative care case conferencing involving general practice: an argument for a facilitated standard process

Objective. To discuss the results of a qualitative analysis of the group dynamics of General Practitioner (GP)-led case conferences for palliative care patients, where the GP becomes the care coordinator. Two outcomes are sought: (1) raise the understanding of this type of case conferencing for palliative care patients; and (2) recommend improvements to this process that will positively affect its efficacy. Methods. Original data is the qualitative component of quantitative and qualitative study of 17 GP-led case conferences for palliative care patients. Data were analysed using Carney’s Ladder of Analytical Abstraction. Results. Analysis produced four persistent themes: ambiguity of purpose; ambiguity of role; lack of information; and involvement of multiple interconnected and dynamic groups. These themes are a natural result of the case conferencing process that occurred during the study. Conclusion. Case conferences were inherently uncertain and complex. Complexity results from the range of people and groups interacting with the patient before the case conference who do not attend the conference. Uncertainty results from a lack of direction, leadership and agreed outcomes against which the conference can be structured and measured. A standard process facilitated by someone other than the GP and containing necessary information would offer a better chance of optimising this process. What is known about the topic? Little is known of the group dynamics that occur during these case conferences. What does this paper add? This paper adds a first assessment of the group dynamics of the process and discloses issues that will need to be addressed if this type of case conferencing is to be optimised. What are the implications for practitioners? Understanding of fundamental issues with the process.

Appraisal of literature reviews on end-of-life care for minority ethnic groups in the UK and a critical comparison with policy recommendations from the UK end-of-life care strategy

BACKGROUND

Evidence of low end-of-life (EoL) care service use by minority ethnic groups in the UK has given rise to a body of research and a number of reviews of the literature. This article aims to review and evaluate literature reviews on minority ethnic groups and EoL care in the UK and assess their suitability as an evidence base for policy.

METHODS

Systematic review. Searches were carried out in thirteen electronic databases, eight journals, reference lists, and grey literature. Reviews were included if they concerned minority ethnic groups and EoL care in the UK. Reviews were graded for quality and key themes identified.

RESULTS

Thirteen reviews (2001-2009) met inclusion criteria. Seven took a systematic approach, of which four scored highly for methodological quality (a mean score of six, median seven). The majority of systematic reviews were therefore of a reasonable methodological quality. Most reviews were restricted by ethnic group, aspect of EoL care, or were broader reviews which reported relevant findings. Six key themes were identified.

CONCLUSIONS

A number of reviews were systematic and scored highly for methodological quality. These reviews provide a good reflection of the primary evidence and could be used to inform policy. The complexity and inter-relatedness of factors leading to low service use was recognised and reflected in reviews' recommendations for service improvement. Recommendations made in the UK End-of-Life Care Strategy were limited in comparison, and the Strategy's evidence base concerning minority ethnic groups was found to be narrow. Future policy should be embedded strongly in the evidence base to reflect the current literature and minimise bias.

An evaluation of aged-care workers' knowledge of and attitudes toward the palliative approach

This study, a cross-sectional survey, evaluated the knowledge of the palliative approach to care of an entire care workforce in an Australian residential aged-care organization (n = 116, 30% response rate). Knowledge deficits were found at all staff levels: RNs lacked a full comprehension of pain and symptom management, and personal care attendants' knowledge scores were not statistically different from those of ancillary staff. RN division 1 reported a more positive attitude toward caring for dying patients than other staff groups. Increasing experience in the field was found to be the main determinant of knowledge of, and attitudes toward, the palliative approach, while increasing hours of palliative care education and higher post-school educational level conferred some benefit. Study findings provide strong impetus for education in the palliative approach to care for the entire interdisciplinary team. With targeted education and support, older residents' needs for a palliative approach to care can be identified by all members of the care team, and appropriate response and/or referral can be achieved.

Improving the Methodologic and Ethical Validity of Best Supportive Care Studies in Oncology: Lessons From a Systematic Review

Purpose

To systematically review the best supportive care (BSC) literature and to evaluate the ethical and methodologic validity issues by using widely acknowledged criteria.

Methods

Two search strings that included both cancer and supportive as terms (with random article type, or review or meta-analysis) explored databases from 1966 to 2008. Citations, abstracts, and papers were reviewed for inclusion criteria, and relevant data were extracted by two independent researchers. Data were validated for accuracy. Ethical and methodologic validity were evaluated by using the criteria derived from the Helsinki Requirements of the WMA; CONSORT statements for the evaluation of reports of randomized, controlled trials; and the universal requirements for ethical clinical research.

Results

Forty-three published papers were identified that described 32 studies, 20 of which incorporated the design of treatment plus supportive care (SC) versus SC alone, and 12 of which incorporated the design of treatment versus SC. Most of the studies had poor compliance to critical Helsinki requirements, to methodologic precautions derived from the CONSORT statement for studies involving a nonpharmacologic arm, and to four of seven universal requirements for ethical clinical research.

Conclusion

Lack of rigor in BSC studies has contributed to a generation of research with widespread ethical and methodologic shortcomings. Ad hoc SC and lack of standardization of SC delivery may be sources of systematic bias or error in BSC trials. Rectifying these shortcomings in future studies demands greater vigilance toward these issues by researchers, institutional review boards, editors, and peer reviewers. Given the prevalence of overlooked problems that are later identified, currently open BSC studies should be reevaluated by institutional review boards and researchers to check for ethical and methodologic validity, and identified shortcomings should be addressed.

Is it feasible and desirable to collect voluntarily quality and outcome data nationally in palliative oncology care?

Hospice/palliative care is a critical component of cancer care. In Australia, more than 85% of people referred to specialized hospice/palliative care services (SHPCS) have a primary diagnosis of cancer, and 60% of people who die from cancer will be referred to SHPCS. The Palliative Care Outcomes Collaboration (PCOC) is an Australian initiative that allows SHPCS to collect nationally agreed-upon measures to better understand quality, safety, and outcomes of care. This article describes data (October 2006 through September 2007) from the first 22 SHPCS, with more than 100 inpatient admissions annually. Data include phase of illness, place of discharge, and, at each transition in place of care, the person's functional status, dependency, and symptom scores. Data are available for 5,395 people for 6,379 admissions. After categorizing by phase of illness and dependency, there remain at the end of each admission 12-fold differences (mean, 26%; range, 4% to 52%) in the percentage of patients who became stable after an unstable phase; seven-fold differences (mean, 22%; range, 6% to 41%) in the percentage of patients with improved symptom scores, five-fold differences (mean, 25%; range, 12% to 64%) in discharge back to the community, four-fold differences (mean, 10%; range, 4% to 16%) in improved function, and three-fold differences in the length of stay (mean, 14 days; range, 6 to 19 days). PCOC shows it is feasible to collect quality national palliative care outcome data voluntarily. Variations in outcomes justify continued enrollment of services. Benchmarking should include all patients whose cancer will cause death and explore observed variations.

How useful are systematic reviews for informing palliative care practice? Survey of 25 Cochrane systematic reviews

BACKGROUND

In contemporary medical research, randomised controlled trials are seen as the gold standard for establishing treatment effects where it is ethical and practical to conduct them. In palliative care such trials are often impractical, unethical, or extremely difficult, with multiple methodological problems. We review the utility of Cochrane reviews in informing palliative care practice.

METHODS

Published reviews in palliative care registered with the Cochrane Pain, Palliative and Supportive Care Group as of December 2007 were obtained from the Cochrane Database of Systematic Reviews, issue 1, 2008. We reviewed the quality and quantity of primary studies available for each review, assessed the quality of the review process, and judged the strength of the evidence presented. There was no prior intention to perform any statistical analyses.

RESULTS

25 published systematic reviews were identified. Numbers of included trials ranged from none to 54. Within each review, included trials were heterogeneous with respect to patients, interventions, and outcomes, and the number of patients contributing to any single analysis was generally much lower than the total included in the review. A variety of tools were used to assess trial quality; seven reviews did not use this information to exclude low quality studies, weight analyses, or perform sensitivity analysis for effect of low quality. Authors indicated that there were frequently major problems with the primary studies, individually or in aggregate. Our judgment was that the reviewing process was generally good in these reviews, and that conclusions were limited by the number, size, quality and validity of the primary studies.We judged the evidence about 23 of the 25 interventions to be weak. Two reviews had stronger evidence, but with limitations due to methodological heterogeneity or definition of outcomes. No review provided strong evidence of no effect.

CONCLUSION

Cochrane reviews in palliative care are well performed, but fail to provide good evidence for clinical practice because the primary studies are few in number, small, clinically heterogeneous, and of poor quality and external validity. They are useful in highlighting the weakness of the evidence base and problems in performing trials in palliative care.

Psychological interventions for women with metastatic breast cancer

BACKGROUND

Systematic reviews of psychological interventions for patients with cancer are conflicting, some showing benefits for patients and others not. One early study appeared to show significant survival and psychological benefits from a psychological intervention given to women with metastatic breast cancer. Subsequent studies have however demonstrated conflicting results.

OBJECTIVES

To assess the effects of psychological interventions (educational, individual cognitive behavioural or psychotherapeutic, or group support) on psychological and survival outcomes for women with metastatic breast cancer.

SEARCH STRATEGY

For this update, the Cochrane Breast Cancer Group Specialised Register was searched (September 2007). Also searched were MEDLINE (1966-September 2006), CINAHL (1982-September 2006), PsycInfo (1974-September 2006), and SIGLE (1980-September 2006).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of psychological interventions for women with metastatic breast cancer. Studies which were not t 'intention to treat' were included owing to the nature of the patient group under study and the likely high loss of follow-up data.

DATA COLLECTION AND ANALYSIS

Data were extracted independently by two reviewers. Data about the nature and setting of the intervention, relevant outcome data and items relating to methodological quality were extracted.

MAIN RESULTS

Five primary studies (511 women) were identified all group psychological interventions. Two of these were cognitive behavioural interventions and three evaluated support-expressive group therapy. The five studies of group psychological therapies showed very limited evidence of benefit arising from these interventions. Although there was evidence of short-term benefit for some psychological outcomes, in general these were not sustained at follow-up. A clearer pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The possible longer survival times in women allocated to receive psychological intervention in the early study have not been replicated in the subsequent four studies (including one by members of the first study group), and overall the effects of these interventions on survival are not statistically significant (for example, odds ratio for 5 year survival 0.83 (95% confidence interval [CI] 0.53 - 1.28).

AUTHORS' CONCLUSIONS

There is insufficient evidence to advocate that group psychological therapies (either cognitive behavioural or supportive-expressive) should be made available to all women diagnosed with metastatic breast cancer. Any benefits of the interventions are only evident for some of the psychological outcomes and in the short term. The possibility of the interventions causing harm is not ruled out by the available data.

Comfort in the last 2 weeks of life: relationship to accessing palliative care services

INTRODUCTION

Specialised palliative care services (SPCS) aim to address the needs of patients and caregivers confronting life-limiting illnesses but only half of the potential cohort are referred. Randomised controlled trials of SPCS provision can no longer be ethically justified so there is a need to develop new methods to evaluate the net impact of SPCS for the whole community, not just for those who access SPCS. The aim of this study was to assess whether perceived comfort in the last 2 weeks of life was associated with accessing SPCS.

METHODS

This study utilised a whole-of-population random survey (n = 4,366) in South Australia. A total of 802 respondents had someone close to them die within the last 5 years due to a terminal illness, and they had the complete data. A subsequent question was asked whether SPCS had been accessed. Perceived comfort levels for those who had used SPCS were compared with those who did not by using stereotype logistic regression, weighted to a standardised population.

RESULTS

Higher levels of comfort of the deceased having been assessed 'very comfortable' was associated with the use of SPCS (p = 0.04; odds ratio, 1.78; 95% confidence interval, 1.02-3.08). For people who accessed SPCS, 13.3% were reported as 'very comfortable' compared with 8.0% without SPCS. Almost one half of respondents (48.4%) reported that the deceased was considered 'uncomfortable' or 'very uncomfortable', irrespective of SPCS access.

DISCUSSION

While this study provides further incremental evidence of benefit from access to SPCS, there is much that still needs to be done to improve care for the whole community at the end of life.

The impact of palliative care on cancer deaths in Hong Kong: a retrospective study of 494 cancer deaths

OBJECTIVES

To study the utilization of public health care by advanced cancer patients in their last 6 months of life and their end-of-life process within the last 2 weeks of life.

METHODS

This was a retrospective study on 494 cancer deaths from four public hospitals in 2005. This sample was selected from all in-patient cancer deaths by the ratio of one in four. Data were collected by review of charts and an electronic data base.

RESULTS

A total of 494 cancer deaths were analysed. The mean age of all cancer patients (n = 494) was 72.6 years. Two-thirds of cancer patients received palliative care and half died in palliative care setting. Patients were categorized into three groups according to palliative care coverage and the place of death. The first group comprised of patients who received palliative care service and died in palliative care units (PCS-PCD group, n = 247); the second group of patients who received palliative care service within the last 6 months of life but died in non-palliative care wards (n = 86); and the third group of patients who never received palliative care and who died in non-palliative care wards (NPCS-NPCD group, n = 161). Differences among groups were tested by one way ANOVA. During the last 6 months of life, patients in the PCS-PCD group had less admission to acute care wards (P = 0.012), shorter duration of stay in acute care wards (P = 0.003), and less admission to an intensive care unit setting (P < 0.001). Within the last 2 weeks of life, the PCS-PCD group had fewer interventions initiated (P < 0.001); had higher number of symptoms documented in patient's record (P < 0.001); and were more likely to receive analgesics (P < 0.001), adjuvant analgesics (P < 0.001) and sedatives (P < 0.001). Patients in PCS-PCD group were more physically dependent in the last 2 weeks of life (P < 0.001), but mentally more alert at 72 hours before death (P < 0.001). Patients in the NPCS-NPCD group had fewer patients with a do not resuscitate order present (P < 0.001), and more patients with cardiopulmonary resuscitation performed (P < 0.001).

CONCLUSION

Our results suggest that palliative care service has played a role in improving end-of-life cancer care in Hong Kong.

Health care system factors affecting end-of-life care

The field of palliative care in the United States developed in response to a public health crisis--namely, poor quality of life for patients with serious illness and their families--and most palliative care research to date has been appropriately focused on identifying patient and family needs and identifying gaps in the current health care system and in the education of our health care professionals. Research has also begun to develop and evaluate new interventions and systems to address these care gaps. Preliminary studies suggest modest benefits of an array of programs designed to deliver palliative care services. These benefits include improved pain and other symptoms, increased family satisfaction, and lower hospital costs. Unfortunately, the validity and reliability of these findings are limited by important methodological weaknesses including small sample sizes, poorly described and nongeneralizable interventions, diverse and nonstandardized outcome measures, and poor study designs (i.e., lack of appropriate control groups, nonblinded designs). Comprehensive and rigorous research is needed to evaluate the effect of well-delineated and generalizable palliative care structures and processes on important clinical and use outcomes. Large multisite studies that have adequate power to detect meaningful differences in clinical and use outcomes, and that use well-defined and generalizable structures and evidence-based care processes, well-defined uniform outcome measures, and analyses that link the outcomes of interest to individual components of the interventions, are needed to guide further development of the field.

Palliative care program effectiveness research: developing rigor in sampling design, conduct, and reporting

Research on palliative care presents some unique sampling challenges. The purpose of this paper is to articulate the sampling challenges that palliative care researchers face during phases of study design, conduct, and the reporting of results. Challenges include identifying a target population, avoiding selection bias in the face of clinician and patient denial of serious illness, developing eligibility criteria for a seriously ill population, minimizing high patient refusals due to illness, and accurate reporting of all screened and eligible participants. These challenges are explored within the context of a randomized clinical trial testing a palliative care intervention. Suggestions for improving scientific rigor in sampling design include 1) defining a target population that is consistent with research goals; 2) identifying eligibility criteria that are objective and understandable to clinicians to yield the desired sample; and 3) reporting results about the target population, sample eligibility/exclusions, and participation using standardized criteria.

A comparison between telephone and bedside consultations given by palliative care consultation teams in the Netherlands: results from a two-year nationwide registration

Palliative Care Consultation (PCC) teams in The Netherlands give support to professional caregivers in palliative care. In contrast to many other countries, consultants only give advice. They do not give prescriptions. Most consultations are given by phone; in some, the consultant also visits the patient. For two years, the PCC teams registered all consultations prospectively on a standard registration form in a nationwide database. The aim of this study was to obtain more insight into the possible differences between telephone and bedsides consultations with regard to characteristics of consultants, requesting caregivers, and the patients, as well as the number and kind of problems discussed. The data demonstrate that bedside consultations show more variety in requesting caregivers and are conducted more often for patients. Bedside consultations also addressed a higher number of problems and a wider range of domains (e.g., psychological, spiritual, daily functioning, and support for informal caregivers). These results suggest that bedside consultations have a surplus value compared to telephone consultations. More rigorous study is needed to compare the relative merits of different methods of consultations in palliative care.

Case studies: a research strategy appropriate for palliative care?

Selecting an appropriate research strategy is key to ensuring that research questions are addressed in a way which has value and is congruent with the overall topic, questions and purpose of the research. This paper will argue that there are situations when a case study strategy is appropriate to use in palliative care research. These include: when complex situations need to be addressed; when context is central to the study; when multiple perspectives need to be recognized; when the design needs to be flexible; when the research needs to be congruent with clinical practice; when there is no strong theory to which to appeal; and when other methodologies could be difficult to conduct. Using case study strategies rigorously and appropriately can contribute to knowledge in a way which is sensitive to the complex, context-dependent and multiprofessional nature of palliative care.

Psychological interventions for women with metastatic breast cancer

BACKGROUND

There have been conflicting results from systematic reviews of psychological interventions for patients with cancer, some showing benefits for patients and others not. One early study appeared to show significant survival benefits as well as psychological benefits from a psychological intervention given to women with metastatic breast cancer. Some further studies have been undertaken, again with conflicting results.

OBJECTIVES

To assess the effects of psychological interventions (educational, individual cognitive behavioural or psychotherapeutic, or group support) on psychological and survival outcomes for women with metastatic breast cancer.

SEARCH STRATEGY

We searched the Cochrane Breast Cancer Group Trials Register (September 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2003), MEDLINE (1966-October 2003), CancerLit (1983-2000), CINAHL (1982-October 2003), PsycInfo (1974-November 2003), and SIGLE (1980-November 2003).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of psychological interventions for women with metastatic breast cancer. Studies were included even if they were not 'intention to treat', owing to the nature of the patient group under study and the likely high loss of follow-up data.

DATA COLLECTION AND ANALYSIS

Data were extracted independently by two reviewers. Data about the nature and setting of the intervention, and the relevant outcome data were extracted, along with items relating to methodological quality.

MAIN RESULTS

Five primary studies were identified, all group psychological interventions. Two of these were cognitive behavioural interventions and three evaluated support-expressive group therapy. The five studies of group psychological therapies for women with metastatic breast cancer showed very limited evidence of benefit arising from these interventions. Although there was evidence of short-term benefit for some psychological outcomes, in general these were not sustained at follow-up. A clearer pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The possible longer survival times in women allocated to receive psychological intervention in the early study have not been replicated in the subsequent four studies (including one by members of the first study group), and overall the effects of these interventions on survival are not statistically significant (for example, odds ratio for 5 year survival 0.83 (95% confidence interval [CI] 0.53 - 1.28).

REVIEWERS' CONCLUSIONS

There is insufficient evidence to advocate that group psychological therapies (either cognitive behavioural or supportive-expressive) should be made available to all women diagnosed with metastatic breast cancer. Any benefits of the interventions are only evident for some of the psychological outcomes and in the short term. The possibility of the interventions causing harm is not ruled out by the available data.

The first 2 years of a palliative care consultation team in the Netherlands

In January 1999 an integrated multidisciplinary palliative care consultation (PCC) team was established in Maastricht in the Netherlands. The team included experts in palliative care who had extensive experience in a variety of settings. One of the major tasks of the PCC team was to give support, information and advice to healthcare professionals caring for terminally ill patients. The PCC team was asked by the government to consecutively register and evaluate all consultations. This article describes these consultations, including information on the requesting caregivers, the patients, the questions asked and the recommendations given in the first 26 months. The results show that the PCC team served the needs of professional caregivers in a variety of settings. Most consultations concerned physical and pharmacological problems and the majority of recommendations were evaluated as positive.
