Testing models of care for terminally ill people who live alone at home: is a randomised controlled trial the best approach?

How is community based 'out-of-hours' care provided to patients with advanced illness near the end of life: A systematic review of care provision

BACKGROUND

Deaths in the community are increasing. However, community palliative care out-of-hours is variable. We lack detailed understanding of how care is provided out-of-hours and the associated outcomes.

AIM

To review systematically the components, outcomes and economic evaluation of community-based 'out-of-hours' care for patients near the end of life and their families.

DESIGN

Mixed method systematic narrative review. Narrative synthesis, development and application of a typology to categorise out-of-hours provision. Qualitative data were synthesised thematically and integrated at the level of interpretation and reporting.

DATA SOURCES

Systematic review searching; MEDLINE, EMBASE, PsycINFO, CINAHL from January 1990 to 1st August 2022.

RESULTS

About 64 publications from 54 studies were synthesised (from 9259 retrieved). Two main themes were identified: (1) importance of being known to a service and (2) high-quality coordination of care. A typology of out-of-hours service provision was constructed using three overarching dimensions (service times, focus of team delivering the care and type of care delivered) resulting in 15 categories of care. Only nine papers were randomised control trials or controlled cohorts reporting outcomes. Evidence on effectiveness was apparent for providing 24/7 specialist palliative care with both hands-on clinical care and advisory care. Only nine publications reported economic evaluation.

CONCLUSIONS

The typological framework allows models of out-of-hours care to be systematically defined and compared. We highlight the models of out-of-hours care which are linked with improvement of patient outcomes. There is a need for effectiveness and cost effectiveness studies which define and categorise out-of-hours care to allow thorough evaluation of services.

Challenges in Palliative Care Research on Family Caregivers: Who Volunteers for Interviews?

Background: Interviews are a common method of data collection in palliative care research because they facilitate the gathering of rich, experiential data that are important for theory and practice. What is less clear is the extent to which those interviewed are representative of the larger group. Objective: The aim of this study was to determine if family caregivers who volunteer to be interviewed were similar or different to those who do not. Design: This study used data from the Caregiving and Bereavement study, a prospective, longitudinal mixed-methods study of family caregivers' general health, quality of life, and grief. Setting/Subjects: The 16 caregivers who volunteered to be interviewed were compared to the 20 who did not. Measurements: Comparisons were made in terms of the caregivers' demographic characteristics as well as measures of their quality of life, general health, general grief, and caregiver prolonged grief (i.e., before death). Results: Compared to caregivers who did not volunteer for an interview, those who volunteered were significantly older and reported less caregiver prolonged grief. Logistic regression showed that for each 1-unit increase in the caregiver prolonged grief score, individuals were 13% less likely to agree to an interview. Conclusions: Research findings based upon family caregivers who volunteer for research interviews might not provide a full picture of their experiences and needs. Researchers are encouraged to consider strategies that sample broadly and promote the participation of the full range of family caregivers in research to address the neglected areas of pre- and postdeath bereavement care.

Are the MORECare guidelines on reporting of attrition in palliative care research populations appropriate? A systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Palliative care trials have higher rates of attrition. The MORECare guidance recommends applying classifications of attrition to report attrition to help interpret trial results. The guidance separates attrition into three categories: attrition due to death, illness or at random. The aim of our study is to apply the MORECare classifications on reported attrition rates in trials.

METHODS

A systematic review was conducted and attrition classifications retrospectively applied. Four databases, EMBASE; Medline, CINHAL and PsychINFO, were searched for randomised controlled trials of palliative care populations from 01.01.2010 to 08.10.2016. This systematic review is part of a larger review looking at recruitment to randomised controlled trials in palliative care, from January 1990 to early October 2016. We ran random-effect models with and without moderators and descriptive statistics to calculate rates of missing data.

RESULTS

One hundred nineteen trials showed a total attrition of 29% (95% CI 28 to 30%). We applied the MORECare classifications of attrition to the 91 papers that contained sufficient information. The main reason for attrition was attrition due to death with a weighted mean of 31.6% (SD 27.4) of attrition cases. Attrition due to illness was cited as the reason for 17.6% (SD 24.5) of participants. In 50.8% (SD 26.5) of cases, the attrition was at random. We did not observe significant differences in missing data between total attrition in non-cancer patients (26%; 95% CI 18-34%) and cancer patients (24%; 95% CI 20-29%). There was significantly more missing data in outpatients (29%; 95% CI 22-36%) than inpatients (16%; 95% CI 10-23%). We noted increased attrition in trials with longer durations.

CONCLUSION

Reporting the cause of attrition is useful in helping to understand trial results. Prospective reporting using the MORECare classifications should improve our understanding of future trials.

Developing a Research Agenda for Adult Palliative Care: A Modified Delphi Study

Background: Little is known about research priorities in adult palliative care. Identifying research priorities for adult palliative care will help in increasing research quality and translation. Objective: The aim was to identify the views of health professionals' research priorities in adult palliative care that lead to development of a palliative care research agenda in Australia. Design: A modified three-round Delphi survey. Setting/Subjects: Palliative care researchers and clinicians in Australia were invited to participate. Results: A total of 25 panelists completed round 1, 14 completed round 2, and 13 completed round 3. Round 1 resulted in 90 research priorities in 13 categories. Round 2 showed consensus agreement on 19/90 research priorities. Round 3 resulted in the top 10 research priorities of the 19 achieving consensus in round 2. Panelists agreed that research is needed on the transition to palliative care; improving communication about prognosis; increasing access to palliative care for indigenous communities, people who wish to remain at home, and people in aged care; addressing family caregivers' needs; promoting patients' and families' decision making; improving cross-cultural aspects of palliative care; determining the effects of assisted dying legislation; and improving bereavement care in rural, remote, and Aboriginal populations. Conclusions: The expert panelists identified the top 10 research priorities for adult palliative care. These identified research priorities are the most urgent topics requiring attention to increase the quality of life of patients requiring palliative care and their family members.

Feasibility of a Cognitive-Behavioral and Environmental Intervention for Sleep-Wake Difficulties in Community-Dwelling Cancer Patients Receiving Palliative Care

BACKGROUND

High rates of sleep-wake difficulties have been found in patients with cancer receiving palliative care. Pharmacotherapy is the most frequently used treatment option to manage these difficulties despite numerous adverse effects and the absence of empirical evidence of its efficacy and innocuity in palliative care.

OBJECTIVE

This pilot study aimed to assess the feasibility and acceptability of a cognitive-behavioral and environmental intervention (CBT-E) to improve insomnia and hypersomnolence in patients with a poor functioning level and to collect preliminary data on its effects.

METHODS

Six patients with cancer receiving palliative care (Eastern Cooperative Oncology Group score 2-3), who had insomnia and/or hypersomnolence, received 1 CBT-E individual session at home. They applied the strategies for 3 weeks. Patients completed the Insomnia Severity Index, the Epworth Sleepiness Scale, a daily sleep diary, and a 24-hour actigraphic recording (7 days) at pretreatment and posttreatment, in addition to a semistructured interview (posttreatment).

RESULTS

Participants found strategies easy to apply most of the time, and none was rated as impossible to use because of their health condition. However, their adherence and satisfaction toward CBT-E were highly variable. Results on the effects of CBT-E were heterogeneous, but improvements were observed in patients with a persistent insomnia disorder.

CONCLUSIONS

The CBT-E protocol tested among this highly selected sample was fairly well received and suggested positive outcomes in some patients, particularly those with an insomnia complaint alone.

IMPLICATIONS

Efforts should be pursued to adapt CBT-E and develop other nonpharmacological interventions, in order to provide an alternative to pharmacotherapy for sleep-wake difficulties in this population.

Feasibility and Pilot Studies in Palliative Care Research: A Systematic Review

CONTEXT

Feasibility and pilot study designs are common in palliative care research. Finding standard guidelines on the structure and reporting of these study types is difficult.

OBJECTIVES

In feasibility and pilot studies in palliative care research, to determine 1) how commonly a priori feasibility are criteria reported and whether results are subsequently reported against these criteria? and 2) how commonly are participants' views on acceptability of burden of the study protocol assessed?

METHODS

Four databases (OVID Medline, EMBASE, CINAHL, and PubMed via caresearch.com.au.) were searched. Search terms included palliative care, terminal care, advance care planning, hospice, pilot, feasibility, with a publication date between January 1, 2012 and December 31, 2013. Articles were selected and appraised by two independent reviewers.

RESULTS

Fifty-six feasibility and/or pilot studies were included in this review. Only three studies had clear a priori criteria to measure success. Sixteen studies reported participant acceptability or burden with measures. Forty-eight studies concluded feasibility.

CONCLUSION

The terms "feasibility" and "pilot" are used synonymously in palliative care research when describing studies that test for feasibility. Few studies in palliative care research outline clear criteria for success. The assessment of participant acceptability and burden is uncommon. A gold standard for feasibility study design in palliative care research that includes both clear criteria for success and testing of the study protocol for participant acceptability and burden is needed. Such a standard would assist with consistency in the design, conduct and reporting of feasibility and pilot studies.

Supporting palliative care clients who live alone: Nurses' perspectives on improving quality of care

BACKGROUND

Terminally ilL people who live alone at home are disadvantaged in terms of their places of care and death and health outcomes. There is a need to trial models of care that can extend the period of care at home for as long as possible for this group. The objective was to explore the experiences of nurses providing care to terminally ill clients who live at home alone and who were receiving either additional care aide support or a personal alarm through an RCT.

METHODS

Nine nurses in a home-based palliative care service in Western Australia completed a questionnaire (82% response rate).

FINDINGS

Client willingness to accept additional support from care aides, development of rapport between the client and care staff, and willingness to use the alarm appropriately all influenced the effectiveness of the models of care. These models of care may negate the need for frequent nurses' visits when nurses feeL confident that the care aide can pass on relevant information or that the client will use the alarm when required.

CONCLUSIONS

Both models of care assisted in meeting the challenges to care provision; however, further larger trials are needed to test whether these might translate into granting clients their wishes regarding places of terminal care and death. This study is the first account of nurses' perspectives on service provision to support palliative care clients who live alone. It has prompted changes in practice and will inform service planning for this growing and challenging population group.

Older people living alone at home with terminal cancer

This study describes the lived experiences of older people coping with terminal cancer and living alone, focusing on how they face challenges of the biographical life changes from their disease progression. Face-to-face semi-structured interviews were conducted in two phases with palliative care clients of a community-based service in Western Australia (2009-2011): Brief interviews with 43 cancer patients who live alone and then in-depth interviews with 8 of them. Using biographical disruption as the analytical framework for interpreting the qualitative data, four main themes emerged: Biographical disruption: adjusting to change; Biographical continuity: preserving normality; Biographical reconstruction: redefining normality; and Biographical closure: facing the end. Biographical disruption was a suitable framework for analysis, permitting identification of the biographical disruptions of the individual's world and the reframing that is undertaken by the individual to maintain autonomy and independence while acknowledging and accepting their closeness to death. Understanding the factors associated with the individual's need to maintain their own identity will enable nurses working with this population to tailor support plans that meet the individuals' needs while maintaining or restoring the person's sense of self. Interventions that directly address end-of-life suffering and bolster sense of dignity and personhood need to be considered.

A qualitative exploration of the experiences of people living alone and receiving community-based palliative care

BACKGROUND

It is projected that in Australia there will be between 28% and 48% of palliative care patients living alone by the year 2031. As such, it will become increasingly important to provide appropriate home-based care in order to support these patients to be cared for and die at home.

AIM

This study explored the experiences of community-based palliative care cancer patients who live alone without a caregiver and what psychosocial issues they face.

METHODS

Face-to-face semistructured interviews were conducted with eight participants, and constant comparison was used for the analysis.

FINDINGS

Four main themes emerged: (1) loss of social networks; (2) maintaining independence; (3) balancing independence and the need for assistance; and (4) planning for the end of life.

DISCUSSION

Participants balanced independence with the need to accept help in order to maintain independence. Participants became more flexible about their preferred place of death.

CONCLUSION

The practice implications for working with people close to death who are living alone are that supports and assistance may be needed to maintain social networks and also a sense of independence.

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 support needs of terminally ill people living alone at home: a narrative review

Context: The number of terminally ill people who live alone at home and without a caregiver is growing and exerting pressure on the stretched resources of home-based palliative care services. Objectives: We aimed to highlight the unmet support needs of terminally ill people who live alone at home and have no primary caregiver and identify specific models of care that have been used to address these gaps. Methods: We conducted a narrative review of empirical research published in peer-reviewed journals in English using a systematic approach, searching databases 2002-2013. This review identified 547 abstracts as being potentially relevant. Of these, 95 were retrieved and assessed, with 37 studies finally reviewed. Results: Majority of the studies highlighted the reduced likelihood of this group to be cared for and die at home and the experiences of more psychosocial distress and more hospital admissions than people with a primary caregiver. Few studies reported on the development of models of care but showed that the challenges faced by this group may be mitigated by interventions tailored to meet their specific needs. Conclusion: This is the first review to highlight the growing challenges facing community palliative care services in supporting the increasing number of people living alone who require care. There is a need for more studies to examine the effectiveness of informal support networks and suitable models of care and to provide directions that will inform service planning for this growing and challenging group.

Promoting psychology to students: embracing the multiplicity of research foci and method

In order for the discipline of psychology to continue to thrive it is imperative that future students are effectively recruited into the field. Research is an important part of the discipline and it is argued that the nature of psychological research is naturally one of multiplicity in topic and methodology and that promoting and highlighting this should be considered as a potentially effective recruitment strategy. In this study, a snap-shot of current research topics and methodologies was collected based on published papers from one typical academic psychology department in Australia. Fifty articles published in the period 2010–2013 were randomly selected and then grouped using content analysis to form topic clusters. Five main clusters were identified and included: Grief and Loss; Psychopathology; Sociocultural Studies; Attachment and Parenting; and Developmental Disorders. The studies spanned the full spectrum of research methodologies from quantitative to qualitative and had implications for assessment practices, diagnosis, prevention and treatment, education, and policy. The findings are discussed in terms of the unique characteristics of psychology as a discipline and how this diversity ought to be utilized as the main selling point of the discipline to future students.

A longitudinal study of end-of-life preferences of terminally-ill people who live alone

As a home death seems to be the perceived ideal, terminally ill people who live alone are at a disadvantage in terms of their place of care and death and little is known about their end-of-life preferences. This study aimed at eliciting patient preferences for their place of care and death longitudinally at two points during their illness trajectory, and reporting on the extent they were able to achieve their place of choice or congruence between preferred and actual place of death. A questionnaire was administered by a researcher in the patients' homes during two visits, 6-12 weeks apart depending on patient prognosis. Forty-three patients of Silver Chain Hospice Care Service in Western Australia participated during 2009-2010. The results indicated that preferences were in favour of either a home or hospice death, with more preferring home as a place of death rather than a place of care. However, overall congruence between preferred and actual place of death was between 53% and 41% dependent on whether it was based on first or second visit preferences respectively. This is the first longitudinal study to elicit the end-of-life preferences of terminally ill people who live alone. As home may not be the preferred location for dying for many patients (nearly half of the patients in this study), ability to die in the place of choice needs to be looked at as a possible indicator of meeting patient needs or as a quality measure in end-of-life care.
