Gaps in Hospice and Palliative Care Research: A Scoping Review of the North American Literature

Background

The demand for hospice and palliative care is growing as a result of the increase of an aging population, which is most prominent in North America. Despite the importance of the topic and an increase in hospice and palliative care utilization, there still are gaps in research and evidence within the field.

Aim

To determine what gaps currently exist in hospice and palliative/end-of-life care research within the context of a North American setting to ensure that future directions are grounded in appropriate evidence.

Methods

Using Arksey and O'Malley's scoping review framework, six peer-reviewed, and four grey electronic literature databases in healthcare and the social sciences were searched in mid-2019. 111 full-text articles were retrieved, with 25 articles and reports meeting the inclusion criteria. Major themes were identified through thematic context analysis: (1) clinical, (2) system access to care, (3) research methodology, and (4) caregiving-related research gaps.

Results

Findings include strategies for engaging stakeholder organizations and funding agencies, implications for other stakeholder groups such as clinicians and researchers, and highlight implications for policy (e.g., national framework discussion) and practice (e.g., healthcare provider education and training and public awareness).

Conclusion

Reviewing and addressing targeted research gaps is essential to inform future directions in Canada and beyond.

Effect of caregiving at end of life on grief, quality of life and general health: A prospective, longitudinal, comparative study

BACKGROUND

Determining the effect of caregiving and bereavement remains a challenge. To date, no study has employed a comparison group to investigate caregivers' grief, quality of life and general health in relation to non-caregivers.

AIM

We aimed to determine how caregivers' grief, quality of life and general health changed following death compared to non-caregivers and whether pre-death grief predicted these outcomes.

DESIGN

A prospective, longitudinal study of family caregivers and a comparison group matched for age, gender and postcode was conducted. All participants completed questionnaires at four points - once pre-death and three times post-death (3-4 months, 6-7 months and 9-10 months).

SETTING/PARTICIPANTS

Participants (N = 70) were family caregivers of persons receiving palliative care, mostly for cancer, recruited from three palliative care providers in Western Australia and matched comparisons recruited from advertisements.

RESULTS

There were significant differences between the caregivers' and comparisons' grief, general health and quality of life at pre-death, 3-4 months and 6-7 months post-death, but not at 9-10 months post-death. The rate of progression in these constructs following death was independent from the intensity of pre-death grief. However, caregiver prolonged grief score significantly predicted prolonged grief score at 6-7 and 9-10 months post-death.

CONCLUSION

It took 9-10 months for the caregivers' grief, general health and quality of life to correspond to the comparison group. These findings present an opportunity for palliative care research and practice to consider how best to support the majority of caregivers without grief complications so that their pre- and post-death support needs are realised.

Family Caregivers' Preparations for Death: A Qualitative Analysis

CONTEXT

Many family caregivers are not prepared for the death of their family member or friend. Palliative care services tend to emphasize the patients' preparation for death rather than caregivers' preparation for, or living after, death. Caregivers' perspectives on anticipating and preparing for death are under-researched, despite preparation being associated with better bereavement outcomes.

OBJECTIVES

The objective was to explore family caregivers' preparations for death.

METHODS

A total of 16 family caregivers of people in receipt of palliative care participated in semi-structured, face-to-face interviews. Transcripts were coded and analyzed using grounded theory techniques.

RESULTS

Analysis yielded two overarching themes: Here and Now centered on the caregivers' focus on the multidimensional and all-consuming nature of caregiving for someone who is near death. Negotiating the Here/After described the tension the caregivers faced in vacillating between focusing on the care during the illness trajectory (Here) and worries and plans for the future (After).

CONCLUSION

This exploratory study is the first to focus solely on family caregivers' experiences of preparing for a death. The caregivers described the complexities of trying to prepare while feeling overwhelmed with demands of caregiving throughout an unpredictable illness trajectory. The caregivers in the present study were cognitively prepared, some were behaviorally prepared, but emotional preparedness was challenging. Services should not assume that all family caregivers are well-prepared for the death. Caregivers would likely benefit from the assessment and promotion of their death preparedness.

Risk and Resilience Factors Related to Parental Bereavement Following the Death of a Child with a Life-Limiting Condition

This paper reviews the theoretical and empirical literature on risk and resilience factors impacting on parental bereavement outcomes following the death of a child with a life-limiting condition. Over the past few decades, bereavement research has focussed primarily on a risk-based approach. In light of advances in the literature on resilience, the authors propose a Risk and Resilience Model of Parental Bereavement, thus endeavouring to give more holistic consideration to a range of potential influences on parental bereavement outcomes. The literature will be reviewed with regard to the role of: (i) loss-oriented stressors (e.g., circumstances surrounding the death and multiple losses); (ii) inter-personal factors (e.g., marital factors, social support, and religious practices); (iii) intra-personal factors (e.g., neuroticism, trait optimism, psychological flexibility, attachment style, and gender); and (iv) coping and appraisal, on parental bereavement outcomes. Challenges facing this area of research are discussed, and research and clinical implications considered.

The meaning and experience of bereavement support: A qualitative interview study of bereaved family caregivers

Objective:

Experiences of bereavement can be stressful and are frequently complicated by emotional, familial, and financial issues. Some—though not all—caregivers may benefit from bereavement support. While considered standard within palliative care services in Australia, bereavement support is not widely utilized by family caregivers. There is little research focused on the forms of bereavement support desired or required by family caregivers, how such care is viewed, and/or how bereavement support is experienced. This study examined the experiences of bereaved family caregivers and their impressions of and interactions with bereavement support.

Method:

This paper reports on one aspect of a broader study designed to explore a range of experiences of patients and caregivers to and through palliative care. Focusing on experiences of bereavement, it draws on qualitative semistructured interviews with 15 family caregivers of palliative care patients within a specialist palliative care unit of an Australian metropolitan hospital. The interviews for this stage of the study were initiated 3–9 months after an initial interview with a family caregiver, during which time the palliative patient had died, and they covered family caregivers' experiences of bereavement and bereavement support. Interviews were digitally audiotaped and transcribed in full. A thematic analysis was conducted utilizing the framework approach wherein interview transcripts were reviewed, key themes identified, and explanations developed.

Results:

The research identified four prevalent themes: (1) sociocultural constructions of bereavement support as for the incapable or socially isolated; (2) perceptions of bereavement support services as narrow in scope; (3) the “personal” character of bereavement and subsequent incompatibility with formalized support, and (4) issues around the timing and style of approaches to being offered support.

Significance of results:

Systematic pre-bereavement planning and careful communication about the services offered by palliative care bereavement support centers may improve receipt of support among bereaved family caregivers in need.

Building Community Capacity in Bereavement Support

Background:

Most bereaved people do not require specialist intervention, yet building community capacity in providing bereavement support is underdeveloped. While family caregivers indicate a need for more information about bereavement, there is little evidence to guide what this information might contain.

Objective:

The study’s purpose was to inform bereavement support by determining the advice people bereaved through expected deaths in palliative care have for others in that situation.

Design:

Four funeral providers posted a questionnaire to previous clients who had used their services 6 to 24 months prior and 678 bereaved people responded.

Setting/Participants:

The sample size for this study comprised 265 bereaved people whose relative used palliative care services.

Measurements:

The questionnaire comprised 82 questions about caregiving, bereavement support, current bereavement-related distress, and 2 open-ended questions concerning their bereavement, one of them on advice they have to other people in the same situation.

Results:

Family caregivers (n = 140) of people who received palliative care responded to the open-ended question about advice for others. An open content analysis yielded 3 themes—preparations for bereavement, utilizing social networks, and strategies for dealing with grief.

Conclusions:

Bereaved family caregivers’ experiential knowledge can be harnessed to progress the development of bereavement care strategies for the good of the community. These responses could be incorporated into information brochures, posters, and other community education avenues in order to upskill palliative care bereavement volunteers and the wider community so that bereaved family caregivers are best supported.

Who needs bereavement support? A population based survey of bereavement risk and support need

This study identifies and describes the profiles of bereavement risk and support needs of a community sample in Australia and tests the fit of the data with the three-tiered public health model for bereavement support. Family members who were bereaved 6–24 months prior to the survey and who were clients of four funeral providers participated (May-July 2013). A postal survey was used to collect information about bereaved people’s experience of caring and perceived satisfaction with any bereavement support provided. The questionnaire included a validated risk assessment screening measure for Prolonged Grief Disorder (PG-13). A total of 678 bereaved people responded. The model predicted that 60% of the sample would be low risk, 30% moderate risk, and 10% high risk. Actual figures were very close at 58.4%, 35.2% and 6.4% respectively. The analysis of the demographic characteristics, experience and impact of caring and bereavement, and satisfaction with support received from a variety of sources revealed differential experiences and needs that align with the expectation of low, moderate, and high bereavement support need, as articulated in the public health model. This is the first empirical test of the public health model of bereavement support. As there is a lack of clear evidence to guide development and allocation of bereavement support programs, the findings have the potential to inform the ability of services, community organizations and informal networks to prioritize care according to each level of bereavement need. This is essential to achieve cost-effective and equitable resource allocation.

The effect of caregiving on bereavement outcome: study protocol for a longitudinal, prospective study

Background

The aim of the current study is to determine the effects of caregiving on bereavement outcome. The study will address two important gaps in the research literature: (1) the relationship between pre-death distress and post-death outcomes and (2) family caregivers’ anticipation and preparation of the death of the person for whom they care.

Methods/Design

We will conduct a longitudinal, prospective study of adult family caregivers of adult patients receiving palliative care. All participants will complete a questionnaire administered at four points – approximately 4–8 weeks prior to bereavement, and 3–4, 6–7, and 9–10 months post-bereavement. The questionnaire includes measures of multidimensional caregiving experiences (strain, distress, positive appraisals, and family wellbeing), caregiver prolonged grief, multidimensional grief responses (despair, panic behaviour, blame and anger, detachment, disorganisation, and personal growth), prolonged grief, quality of life, general health (psychological and physical) and demographics. These caregivers’ data will be compared to a comparison group matched for age, sex, and postcode, allowing the caregivers’ general health and quality of life to be compared to a normative group. The caregivers will also be invited to participate in a semi-structured interview about preparing for impending bereavement.

Discussion

This is the first study to address the methodological limitations in the current literature and will likely make a significant contribution to both our understanding of caregiving on bereavement outcome and to bereavement care offered in palliative and hospice settings.

Risk Factors for Anticipatory Grief in Family Members of Terminally Ill Veterans Receiving Palliative Care Services

Anticipatory grief is the process associated with grieving the loss of loved ones in advance of their inevitable death. Because anticipatory grief has been associated with a variety of outcomes, risk factors for this condition deserve closer consideration. Fifty-seven family members of terminally ill, hospice-eligible veterans receiving palliative care services completed measures assessing psychosocial factors and conditions. Elevated anticipatory grief was found in families characterized by relational dependency, lower education, and poor grief-specific support, who also experienced discomfort with closeness and intimacy, neuroticism, spiritual crisis, and an inability to make sense of the loss. Thus, in this sample, anticipatory grief appears to be part of a cluster of factors and associated distress that call for early monitoring and possible intervention.

Between worlds: the experiences and needs of former family carers

While the financial, physical and psycho-social burden for caregivers is recorded, less is known about the post-caring experience. The purpose of this qualitative descriptive study was to explore the experiences and needs of Irish former family carers in the post-caring/care transitions period. Former family carers were defined as family members who provided physical and/or social care to a family member with an illness or disability in the home for at least 6 months prior to nursing home/hospice placement or death. A total of 40 family carers were recruited from members of or known to voluntary care groups/associations in Ireland. Fourteen participants took part in a focus group discussion and 26 participated in one-to-one, semi-structured interviews, all of which were undertaken in 2010. The focus group discussion focused on gaining a broad understanding of the participants' post-caring experiences and the emergent themes formed the basis for the development of a semi-structured interview guide. Data from the focus group were analysed inductively using Creswell's qualitative analysis framework, while template analysis was the method of analysis for the 26 individual interviews. For the participants in this study, post-caring was a transition that comprised three, interrelated, non-linear, iterative themes that were represented as 'loss of the caring world', 'living in loss' and 'moving on' and symbolised as being 'between worlds'. Transition was a complex interplay of emotions overlaid with economic and social concerns that had implications for their sense of health and well-being. This exploratory study begins to address the dearth of data on post-caring/care experiences, but further research is needed to inform support interventions to enable former family carers to 'move on'.

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.
