A psycho-educational intervention for family caregivers of patients receiving palliative care: a randomized controlled trial

Living with hope: developing a psychosocial supportive program for rural women caregivers of persons with advanced cancer

Background

Hope is defined by caregivers as the inner strength to achieve future good and to continue care giving. Pilot test findings of a Living with Hope Program (LWHP) suggested it is an acceptable and feasible intervention for use by family caregivers. Although it shows promise in potentially increasing hope and quality of life, further testing and development is needed. Questions remain as to: a) what are the mechanisms through which the LWHP affects outcomes and b) how long it is effective? The overall purpose of this time series mixed method study is the further development and testing of the LWHP by:

a. Determining the mechanisms of the LWHP by testing a LWHP conceptual model in which self-efficacy, and loss/grief are hypothesized intermediary variables for changes in hope, and subsequently quality of life among rural women caring for persons with advanced cancer, and;

b. Exploring the longitudinal effects of the LWHP on hope, quality of life and health services utilization among rural women caring for persons with advanced cancer.

Methods/Design

Using a time-series embedded mixed method design, data will be collected from 200 rural women caregivers. Following the collection of baseline and outcome variables, the intervention (LWHP) is applied to all subjects. Subjects are followed over time with repeated measures of outcome variables (1 wk, 2 wk, 3, 6 and 12 months). The journals that are completed as part of the LWHP comprise the qualitative data. Health services utilization data will be collected from the Saskatchewan Health Administrative Database for all subjects one year prior and one year after study enrolment.

Path analysis will be used to test the model post LWHP, at 1 and 2 weeks. Two-factor ANCOVA will determine patterns over time and Cortazzi's narrative analysis will be used to analyze subjects journals completed as part of the LWHP.

Discussion

Data Collection began January 2009 and is expected to be completed within 2 years time. Monthly meetings with data collectors and site collaborators have been instrumental in revisions to the original study protocol such as identifying and adding additional study sites.

Development, psychometric testing, and revision of the Atlanta Heart Failure Knowledge Test

BACKGROUND AND RESEARCH OBJECTIVE

Several heart failure (HF) knowledge tools have been developed and tested over the past decade; however, they vary in content, format, psychometric properties, and availability. This article details the development, psychometric testing, and revision of the Atlanta Heart Failure Knowledge Test (A-HFKT) as a standardized instrument for both the research and clinical settings.

PARTICIPANTS AND METHODS

Development and psychometric testing of the A-HFKT were undertaken with 116 New York Heart Association (NYHA) class II and III community-dwelling HF patients and their family members (FMs) participating in a family intervention study. Internal consistency, reliability, and content validity were examined. Construct validity was assessed by correlating education level, literacy, dietary sodium ingestion, medication adherence, and healthcare utilization with knowledge.

RESULTS

Content validity ratings on relevance and clarity ranged from 0.55 to 1.0, with 81% of the items rated from 0.88 to 1.0. Cronbach alpha values were .84 for patients, .75 for FMs, and .73 for combined results. Construct validity testing revealed a small but significant correlation between higher patient and FM knowledge on sodium restriction questions and lower ingested sodium, r = -0.17, P = .05 and r = -0.19, P = .04, respectively, and between patient knowledge and number of days that medications were taken correctly (diuretics: r = 0.173, P < .05, and angiotensin-converting enzyme: r = 0.223, P = .01). Finally, patients seeking emergency care or requiring hospitalization in the 4 months before study entry were found to have significantly lower FM knowledge using both t test and logistic regression modeling.

CONCLUSIONS

The A-HFKT was revised using the content and construct validity data and is available for use with HF patients and FMs. The construct validity testing indicates that patient knowledge has a significant relationship to aspects of self-care. Furthermore, family knowledge may influence patient adherence with sodium restriction and healthcare utilization behavior.

Teaching family carers about home-based palliative care: final results from a group education program

Without the considerable support provided by family carers, many patients receiving palliative care would be unable to remain at home. However, family carers typically lack the required information and skills to prepare them for such a role. Pilot work has demonstrated that group education programs for family carers can be readily developed; they are feasible, accessible, and useful. This project sought to build on our pilot research to further examine the effectiveness of a group education program by evaluating the outcomes with a larger number of participants. The program aimed to prepare primary family carers for the role of supporting a relative with advanced, noncurative cancer at home. The psycho-educational program consisted of three consecutive weekly sessions presented in a group format, conducted at six home-based palliative care services across metropolitan and regional Victoria, Australia. The following dependent variables were measured at three time points: carer competence, preparedness, rewards, and information needs. The three time points were: commencement of the program (Time 1), upon completion (Time 2), and two weeks later (Time 3). A total of 156 participants (including the pilot phase) completed Time 1 questionnaires and 96 completed all three time periods (62%). Between Time 1 and Time 2, the intervention had a statistically significant positive effect on preparedness, competence, rewards, and having informational needs met. Outcomes were maintained at Time 3. There was no difference in the effectiveness of the intervention for participants in regional areas compared to participants in metropolitan areas. This study demonstrated that a group education program to prepare family carers for the role of supporting a dying relative at home was effective. Implications for further research and practice are outlined.

Strength through adversity: Bereaved cancer carers' accounts of rewards and personal growth from caring

Objective:

Many studies have identified negative and distressing consequences experienced by informal cancer carers, but less attention has been given to positive and beneficial aspects of caring. This qualitative study examined the positive aspects of caring as subjectively constructed by bereaved informal cancer carers, a group of individuals who are in a position to make sense of their caring experiences as a coherent whole.

Method:

Twenty-three bereaved informal cancer carers were interviewed, and their accounts were analyzed using a thematic analytical approach from a phenomenological perspective.

Results:

The participants were able to identify positive and beneficial aspects of caring. These included the discovery of personal strength, through adversity, acceptance, and necessity; the deepening of their relationship with the person for whom they cared; and personal growth through altered relationships with others and altered perspectives on living. Many participants gave accounts of focusing on these positive benefits when they reflected on their caring experiences.

Significance of results:

We concluded that benefit finding in the face of adverse events serves an important function in allowing individuals to incorporate difficult experiences into their worldview in a meaningful way, thus maintaining positive beliefs about the world. This has implications for the development of interventions for informal cancer carers and for those who are bereaved following caring.

Bereaved informal cancer carers making sense of their palliative care experiences at home

This qualitative study explored the positive meanings constructed and ascribed to the experience of providing palliative care at home by bereaved informal cancer carers, a group of individuals who are in a position to make sense of their caring experiences as a coherent whole. Twenty-two bereaved cancer carers, living in New South Wales (NSW), Australia, were interviewed as part of a larger mixed-method study examining the experience of informal cancer care. Participants were recruited through cancer support groups and cancer clinics, and through the Cancer Council NSW. Accounts of positive aspects of palliative caring were analysed using a thematic analytical approach from a constructionist perspective. The findings indicated that these bereaved carers gave accounts that accentuated the benefit and satisfaction derived from providing direct palliative care at home, which enabled them to construct positive meanings associated with their participation in the dying process, and as a result to ascribe subjectively meaningful interpretations to their loved ones' death and their sense of loss. This included a sense of reward for doing something good, meeting the expressed needs of the patient, continuing with normal life as much as possible, improving the conditions of the relationship and meeting cultural expectations of the right thing to do. Being present at the point of death was positioned as rewarding because it facilitated the process of saying goodbye, fostered inclusion of others, provided closure and was a spiritual experience. These findings suggest that there are positive and rewarding aspects associated with providing informal cancer care in a palliative context, and these aspects were pertinent and meaningful for carers in their endeavours to reconcile the difficulties and loss they experienced. This has implications for the prevention and amelioration of distress experienced by informal cancer carers, and suggests that future research should not ignore the positive aspects of providing palliative care.

Psychometric properties of the Hospital Anxiety and Depression Scale in family caregivers of palliative care patients

The Hospital Anxiety and Depression Scale (HADS) has been used extensively as a screening tool for anxiety and depression in clinical and nonclinical groups. A number of published studies have provided support for the original bidimensional structure of the HADS; however, others have reported irregularities in the factor structure. This study investigated the psychometric properties of the HADS in 106 family caregivers caring for a patient dying of cancer. Caregivers had been recruited to a randomized controlled trial conducted to gain a longitudinal understanding of caregivers' appraisal of their role. Exploratory factor analysis and internal consistency reliability statistics were used to investigate the underlying structure of the HADS. Descriptive statistics were calculated for author-defined subscale scores to assess levels of anxiety and depression among family caregivers. Two- and three-factor models were explored; however, the two-factor model, which closely resembled the intended bidimensional structure, was preferred. Mean author-defined subscale scores indicated higher levels of anxiety and depression in family caregivers than those previously reported for various general population, general practice, and cancer patient samples. Routine screening of anxiety and depression in family caregivers appears warranted based on the results of this study. The HADS may be a suitable screening tool, as indicated by its bidimensional structure; however, further research is required to establish its diagnostic efficiency in this population.

A narrative review of interventions to support family carers who provide physical care to family members with cancer

OBJECTIVES

Most reports of cancer caregivers' needs focus on information and psychosocial needs. Less is known about practical knowledge and support carers need to provide physical care in the home. This review aimed to identity and critique studies of the development and/or evaluation of interventions to enable family carers to provide physical/practical care to a family member with cancer.

DESIGN

Narrative review.

DATA SOURCES

Studies which included adult carers who provided care to a family member with cancer (any stage). Search sources included Psych Info., Cochrane Central Register of Controlled Trials, Embase Ovid, Embase, Ovid Medline, CINAHL, other databases, systematic and other reviews.

REVIEW METHODS

All types of study designs were included. Initially, multiple and broadly defined search strategies and terms were used to capture the range of potential studies; later more refined procedures were applied.

RESULTS

In total, 19 studies were included in the review. Interventions focused on skills development (n=1), managing symptoms (n=9), problem solving (n=5) and learning (n=4). Few studies were identified with well-defined and evaluated interventions to assist carers to provide physical care for their family member with cancer.

CONCLUSIONS

Future research is needed to develop well-defined interventions on practical skills and evaluate the outcomes for patients and caregivers.

Family meetings in palliative care: are they effective?

Despite the promotion of family meetings as an essential tool for information sharing and planning in palliative care, minimal evidence exists to show their effectiveness. We sought to rectify this gap in evidence-based practice by evaluating recently developed clinical guidelines for facilitating family meetings. Palliative care nurses were trained to conduct family meetings using the guidelines. To assess the effectiveness of the guidelines, primary family carers who attended a family meeting completed a self-report instrument to measure unmet needs at three time periods: immediately before the meeting (T1), immediately after the meeting (T2) and two days after the meeting (T3). Phone interviews with carers were also conducted at T3. Patients, health professionals and family meeting facilitators were also invited to complete an evaluation form at T2. A focus group was conducted at the end of the project to gain reflections from the family meeting facilitators about their role, re-evaluate the family meeting clinical guidelines and discuss barriers and facilitators for ongoing implementation. Twenty family meetings were conducted at St Vincent's Hospital (Melbourne, Australia). A total of 42 participants were involved, including 20 family carers, 4 patients and 18 health professionals. Family carers reported a statistically significant increase in having their care needs met, from T1 to T2, which was maintained at T3; they also reported that the meetings were useful. Health professionals and patients advised that the meetings were well facilitated. The results from this pilot study indicate that family meetings, conducted using specific clinical practice guidelines, were useful and effective. However, more research is required to confirm these findings. Strategies for implementation and further research are outlined.

Family meetings in palliative care: Multidisciplinary clinical practice guidelines

Background

Support for family carers is a core function of palliative care. Family meetings are commonly recommended as a useful way for health care professionals to convey information, discuss goals of care and plan care strategies with patients and family carers. Yet it seems there is insufficient research to demonstrate the utlility of family meetings or the best way to conduct them. This study sought to develop multidisciplinary clinical practice guidelines for conducting family meetings in the specialist palliative care setting based on available evidence and consensus based expert opinion.

Methods

The guidelines were developed via the following methods: (1) A literature review; (2) Conceptual framework; (3) Refinement of the guidelines based on feedback from an expert panel and focus groups with multidisciplinary specialists from three palliative care units and three major teaching hospitals in Melbourne, Australia.

Results

The literature review revealed that no comprehensive exploration of the conduct and utility of family meetings in the specialist palliative care setting has occurred. Preliminary clinical guidelines were developed by the research team, based on relevant literature and a conceptual framework informed by: single session therapy, principles of therapeutic communication and models of coping and family consultation. A multidisciplinary expert panel refined the content of the guidelines and the applicability of the guidelines was then assessed via two focus groups of multidisciplinary palliative care specialists. The complete version of the guidelines is presented.

Conclusion

Family meetings provide an opportunity to enhance the quality of care provided to palliative care patients and their family carers. The clinical guidelines developed from this study offer a framework for preparing, conducting and evaluating family meetings. Future research and clinical implications are outlined.

Review Article: End-of-Life Care for Old People: A Review of the Literature

The aim of this study was to make an inventory of various aspects of end-of-life care of the old people. An additional aim was to illuminate gaps in existing knowledge. A systematic literature review focusing on intervention studies was carried out. Three concepts were of special interest: end-of-life care, palliative care, and terminal care. The result encompassed 29 studies, and the articles were grouped together under 4 headings: education and support for close relatives, education and support for staff, education and support for patients, and articles dealing with care planning. The result highlights the need for further research regarding end-of-life care in geographical and cultural settings that differ from those in the USA, needs of old people (ie, 80+), preferences concerning end-of-life care, and the effect of adjusted and generalizable palliative care models.

Supporting the carers of individuals affected by colorectal cancer

Colorectal cancer is one of the most common cancers, and many difficulties may be experienced as a direct consequence of the disease and its treatment. These can be alleviated and/or resolved with appropriate care. Much of this care is provided informally by the individual's family and friends, whose care needs may be practical, emotional, financial, spiritual or organizational in nature. Care requirement can, as a consequence, be variable in its responsibilities, regularity and duration, since the individual diagnosed with colorectal cancer may require a wide range of support throughout their cancer journey, or have only a few temporary care needs, depending on their disease, treatment and a multitude of other personal, interpersonal and contextual factors. This highlights the importance of regular and individualized assessment. The caregiver's role is often forgotten and hence the impact it may be having upon their own health and lives gets overlooked. Yet, a carer's ability to manage this role has an important bearing not only on patient experience but also on the level of professional involvement. To perform this role satisfactorily carers need to be prepared, supported and also assessed at key points in the patient's cancer journey. Nurses have a professional obligation to help carers by first preparing them, then maintaining sufficient contact to be able to proactively provide practical support and additional health care as needed. This article focuses on these carers and highlights the scope, associated challenges and possible consequences of the caring role. It also seeks to stimulate reflection of how current service provision for carers might be improved.

Family influences on heart failure self-care and outcomes

Many patient education guidelines for teaching heart failure patients recommend inclusion of the family; however, family-focused interventions to promote self-care in heart failure are few. This article reviews the state of the science regarding family influences on heart failure self-care and outcomes. The literature and current studies suggest that family functioning, family support, problem solving, communication, self-efficacy, and caregiver burden are important areas to target for future research. In addition, heart failure patients without family and those who live alone and are socially isolated are highly vulnerable for poor self-care and should receive focused attention. Specific research questions based on existing science and gaps that need to be filled to support clinical practice are posed.

Evaluation of a psycho-educational group programme for family caregivers in home-based palliative care

BACKGROUND

Family caregivers are often responsible for providing significant support to relatives who require palliative care at home. However, evidence suggests that family caregivers have limited information, resources or support to prepare them for such a role. Furthermore, family caregiving can be associated with negative physical, financial and psychosocial outcomes.

PURPOSE

This project sought to examine the utility of a group family caregiver psycho-educational programme focused on preparing primary family caregivers for the role of supporting a relative with advanced cancer at home.

METHOD

The education programme consisted of three consecutive weekly sessions presented in a group format, conducted at six home-based palliative care services across metropolitan and regional Victoria (Australia). Participating caregivers were required to complete a set of self-report questionnaires measuring caregiver competence, preparedness, optimism, rewards, social support, burden and information needs, at three time points: commencement of the programme (T1), upon completion (T2) and 2 weeks later (T3). Caregivers were also asked to report on the relevance, acceptability and content of the programme, as well as any barriers to access.

RESULTS

Sixteen education programmes were conducted, with 74 caregivers attending the first session. Forty-four caregivers completed all three data collection sets. Following the intervention, a significant positive effect was found for the following outcomes: preparedness for the caring role, caregiving competence, caregiving rewards and having information needs met from T1 to T2. These improvements were maintained at follow-up (T3). Feedback on the individual sessions and entire programme was favourable and the overwhelming majority of participants reported that the programme had a positive impact on their lives.

CONCLUSIONS

This study demonstrated that a group education programme to prepare family caregivers for the role of supporting a dying relative at home was accessible, applicable and effective.

Effects of caregiving demand, mutuality, and preparedness on family caregiver outcomes during cancer treatment

PURPOSE/OBJECTIVES

To test a model of family caregiving derived from the interactionist approach to role theory that hypothesized that three caregiving role implementation variables (caregiving demand, mutuality between caregivers and patients, and preparedness for caregiving) would predict multiple caregiving-specific and generic outcomes with different patterns of association across outcomes.

DESIGN

Descriptive, correlational.

SETTING

Surgical, radiation, and medical oncology settings.

SAMPLE

87 family caregivers of adults receiving treatment for solid tumors or lymphoma.

METHODS

Caregivers completed the Demand and Difficulty subscales of the Caregiving Burden Scale; the Mutuality, Preparedness, and Global Strain scales of the Family Care Inventory; and the 30-item short form of the Profile of Mood States. Data were analyzed with simultaneous multiple regression.

MAIN RESEARCH VARIABLES

Caregiving demand, mutuality, preparedness, caregiving difficulty, global caregiver strain, tension, depression, anger, fatigue, vigor, confusion, and total mood disturbance.

FINDINGS

The model explained statistically significant proportions of variance in each outcome, with different patterns of association across outcomes. Demand was associated most strongly with caregiving difficulty and global strain. Mutuality was associated most strongly with caregiver anger. Unexpectedly, preparedness was associated more strongly with mood disturbance outcomes than with the caregiving-specific variables of difficulty and strain.

CONCLUSIONS

Further research should explore models that address implementation of the caregiving role to better elucidate how family caregivers learn and carry out the important role.

IMPLICATIONS FOR NURSING

Clinical assessment should include caregiving demand, the quality of the relationship between caregiver and patient, and preparedness for caregiving. Interventions could be tailored to meet caregiver needs in each area.

The management of family conflict in palliative care

We review the literature on family conflict in palliative care. The prevalence and common sources of conflict are discussed, including historical issues of tension, differing coping styles, the division of labour, and the presence of acute or chronic mental illness within the family. Assessment and intervention strategies used in Family Focused Grief Therapy (FFGT), a family-centred preventive intervention that begins during palliative care and continues during bereavement, are presented, with special consideration given to research on treatment decision-making, cultural issues, special-needs populations, and the management of crises within the family. We conclude with a discussion of challenges that frequently impede conflict resolution and with suggestions for addressing these difficulties in the palliative care setting.

Mutuality and preparedness moderate the effects of caregiving demand on cancer family caregiver outcomes

BACKGROUND

Family caregiving researchers have explored the moderating or stress-buffering effects of variables such as coping and social support. However, the quality of the family caregiver-patient relationship and preparedness for caregiving have received little attention as potential moderators.

OBJECTIVE

To explore whether relationship quality and preparedness moderate the effects of caregiving demand on caregiver outcomes during cancer treatment.

METHODS

Eighty-seven family caregivers of patients receiving treatment for cancer completed the Demand and Difficulty subscales of the Caregiving Burden Scale, Mutuality and Preparedness Scales of the Family Care Inventory, and the short form of the Profile of Mood States. Using hierarchical multiple regression analyses, caregiving difficulty and total mood disturbance were regressed on two- and three-way interaction terms for demand, mutuality, and preparedness, controlling for caregiver age and gender, and the simple effect of each independent variable.

RESULTS

Negligible effects for two-way interactions were found. However, the three-way interaction between demand, mutuality, and preparedness explained statistically significant variance in both perceived difficulty of caregiving and total mood disturbance. High mutuality in combination with high preparedness protected caregivers from adverse outcomes when demand was high. When either mutuality or preparedness was low, caregivers were at greater risk for negative outcomes when demand was high, but not when demand was low. When both mutuality and preparedness were low, caregivers were at risk for mood disturbance even when demand was low.

DISCUSSION

Analysis of three-way interactions provided new theoretical insights into the protective effects of mutuality and preparedness and demonstrated conditions under which caregivers are at increased risk for negative outcomes.

Improving well-being in caregivers of terminally ill patients. Making the case for patient suffering as a focus for intervention research

Family caregivers are integral to the care of patients with physical or mental impairments. Unfortunately, providing this care is often detrimental to the caregivers' health. As a result, in the last decade, there has been a proliferation of interventions designed to improve caregivers' well-being. Interventions for caregivers of persons at end of life, however, are relatively few in number and are often underdeveloped. They also are typically designed to help reduce the work of caregiving or to help caregivers cope with the physical and emotional demands of providing care. Although useful, these interventions generally ignore a primary stressor for family caregivers -- a loved one's suffering. Patient suffering, whether physical, psychosocial, or spiritual, has a major impact on family caregivers. However, interventions that focus on the relief of patient suffering as a way to improve caregiver well-being have rarely been tested. It is our view that more research in this area could lead to new and more effective interventions for family caregivers of seriously or terminally ill patients. In support of our view, we will define suffering and review the relationships between patient suffering and caregiver well-being. We will then discuss a conceptual framework for intervention design. Finally, we conclude with a discussion of implications and future directions for intervention research.

Caregiving at the End of Life

This paper provides a review of family caregiving for adult patients with serious, lifethreatening illness. Areas covered include the (1) epidemiology of family caregiving, (2) cross-cultural issues in caregiving, (3) impact of caregiving on families, (4) similarities and differences involved in providing care for patients with various illnesses, and (5) interventions for family caregivers. The importance of family caregiving to palliative care practice is emphasized.

How Well Do Family Caregivers Cope after Caring for a Relative with Advanced Disease and How Can Health Professionals Enhance their Support?

BACKGROUND

Support for families during a person's advanced disease and also into the bereavement period is a major component of palliative care. However, because of the gaps in bereavement research in this area, there is a lack of evidence-based direction for health professionals.

PURPOSE

This study sought to explore family caregiver perceptions of their relative's death and assess how well they were coping. Caregivers were also asked to identify which health professional strategies helped them prepare for and respond to their relative's death.

METHODS

Two months after their relative's death primary family caregivers (n=45) of patients with advanced cancer completed a structured interview and were also assessed to determine if they were confronted by traumatic grief.

RESULTS

Seven percent of caregivers were confronted by traumatic grief; most caregivers perceived they were coping reasonably well and could identify positive outcomes related to their experience. Caregivers noted the significant benefits of receiving comprehensive information to prepare them for the future and expressed appreciation for the support provided by specialist palliative care services.

CONCLUSIONS

There is a large body of literature that highlights the negative consequences of being a family caregiver to a person with advanced disease. The sample population in this study, however, seemed to be reasonably well functioning; the results of the study were therefore somewhat surprising. A research agenda and key clinical implications are outlined in order to aid direction in targeting bereavement interventions.

Measuring the psychosocial characteristics of family caregivers of palliative care patients: psychometric properties of nine self-report instruments

Researchers and clinicians have experienced substantial difficulties locating measures that are suitable for use within palliative care settings. This article details the psychometric properties of nine instruments designed to assess the following psychosocial characteristics of family caregivers: competence, mastery, self-efficacy, burden, optimism, preparedness, social support, rewards, and mutuality. Results are based on the responses of 106 primary family caregivers caring for relatives dying of cancer. Principal components extraction with varimax rotation was used to explore the underlying structure of each measure. Following the exclusion of complex variables, suggested components for most measures comprised relatively homogenous items, which were good to excellent measures of each component. Some components comprised only two items; however, Cronbach's alphas typically indicated moderate to high levels of internal consistency. Overall, the results of this study suggest that most of the measures analyzed, excepting the mastery and mutuality scales, can be recommended to examine the family caregiver experience and test supportive interventions.
