Research design in end-of-life research: state of science

People with HIV at the end-of-life and their next-of-kin/loved ones are willing to participate in interventional HIV cure-related research

INTRODUCTION

The Last Gift study at the University of California San Diego (UCSD), United States enrolls terminally ill people with HIV (PWH) in HIV cure research.

METHODS

From 2017 to 2022, we conducted surveys with Last Gift participants and their next-of-kin/loved ones to evaluate willingness to participate in different types of HIV cure research at the end of life (EOL). We analyzed willingness data descriptively.

RESULTS

We surveyed 17 Last Gift participants and 17 next-of-kin/loved ones. More than half of Last Gift participants ( n  = 10; 58.8%) expressed willingness to participate in studies involving totally new treatments or approaches ('first-in-human' studies), a combination of different approaches, the use of unique antibodies, proteins or molecules, or therapeutic vaccines. Under one-quarter of Last Gift participants ( n  = 4; 23.5%) expressed willingness to participate in research involving interventions that may shorten their life expectancy to benefit medical research. Most Last Gift participants and their next-of-kin/loved ones also expressed high acceptance for various types of donations and biopsies at the EOL (e.g. hair donations and skin, lymph node or gut biopsies).

DISCUSSION

Knowing whether people would be willing to participate in different types of EOL HIV cure research can help inform the design of future innovative studies. As a research community, we have a duty to design studies with adequate safeguards to preserve the public trust in research and honor PWH's important gift to humanity.

Lessons learned from the Last Gift study: ethical and practical challenges faced while conducting HIV cure-related research at the end of life

The Last Gift is an observational HIV cure-related research study conducted with people with HIV at the end of life (EOL) at the University of California San Diego. Participants agree to voluntarily donate blood and other biospecimens while living and their bodies for a rapid research autopsy postmortem to better understand HIV reservoir dynamics throughout the entire body. The Last Gift study was initiated in 2017. Since then, 30 volunteers were enrolled who are either (1) terminally ill with a concomitant condition and have a prognosis of 6 months or less or (2) chronically ill with multiple comorbidities and nearing the EOL.Multiple ethical and logistical challenges have been revealed during this time; here, we share our lessons learnt and ethical analysis. Issues relevant to healthcare research include surrogate informed consent, personal and professional boundaries, challenges posed conducting research in a pandemic, and clinician burnout and emotional support. Issues more specific to EOL and postmortem research include dual roles of clinical care and research teams, communication between research personnel and clinical teams, legally required versus rapid research autopsy, identification of next of kin/loved ones and issues of inclusion. Issues specific to the Last Gift include logistics of body donation and rapid research autopsy, and disposition of the body as a study benefit.We recommend EOL research teams to have clear provisions around surrogate informed consent, rotate personnel to maintain boundaries, limit direct contact with staff associated with clinical care and have a clear plan for legally required versus research autopsies, among other recommendations.

Lessons for Understanding Central Nervous System HIV Reservoirs from the Last Gift Program

PURPOSE OF REVIEW

Deep tissue HIV reservoirs, especially within the central nervous system (CNS), are understudied due to the challenges of sampling brain, spinal cord, and other tissues. Understanding the cellular characteristics and viral dynamics in CNS reservoirs is critical so that HIV cure trials can address them and monitor the direct and indirect effects of interventions. The Last Gift program was developed to address these needs by enrolling altruistic people with HIV (PWH) at the end of life who agree to rapid research autopsy.

RECENT FINDINGS

Recent findings from the Last Gift emphasize significant heterogeneity across CNS reservoirs, CNS compartmentalization including differential sensitivity to broadly neutralizing antibodies, and bidirectional migration of HIV across the blood-brain barrier. Our findings add support for the potential of CNS reservoirs to be a source of rebounding viruses and reseeding of systemic sites if they are not targeted by cure strategies. This review highlights important scientific, practical, and ethical lessons learned from the Last Gift program in the context of recent advances in understanding the CNS reservoirs and key knowledge gaps in current research.

Predicting death quality from life prior to death among older Chinese in a retrospective cohort study

Background

The pursuit of a good death is crucial in aging societies. This retrospective cohort study investigated the relation between life prior to death and quality of death among older Chinese.

Methods

End-of-life data reported by relatives of participants (aged 54 and over) from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) who deceased between January 2011 and June 2019 were utilized. Life prior to death included health condition (morbid or not) and physical functioning (a latent factor with six indicators). Quality of death was assessed by painlessness and consciousness at death. Confirmatory Factor Analysis was employed to examine the factor structure of physical functioning and Structural Equation Modeling to explore associations between life prior to death and death quality based on sex and residence location.

Results

Freedom from chronic diseases was found to contribute to high-quality deaths (i.e., being painless and conscious) both directly and indirectly by enhancing physical functioning. Men and women diverged toward end-of-life: women were moderately less liable to illnesses and thus less painful at death. Yet, men functioned much better, and more often remained conscious when dying. Location's effect was weaker: although rural residents were more prone to painful deaths than urban dwellers, this urban-rural divide was slightly narrowed by rural settlers' relative health, which also indirectly led to their slight advantage in consciousness at death.

Conclusions

The results suggested that different dimensions of life prior to death predicted quality of death. Additionally, morbidity's effect on functioning and death quality stresses health management's role in improving end-of-life experiences.

Beyond Advance Directives: Addressing Communication Gaps and Caregiving Challenges at Life's End

CONTEXT

The premise of advance directives and care planning is to help people articulate and document their wishes so surrogate decision-makers and providers can honor them. However, beyond the completion of such a document, underlying challenges are often unaddressed OBJECTIVES: The overall purpose of the study was to investigate how communication, including but not limited to the completion of advance directives, and caregiving influenced family caregivers' experiences. Communication gaps and caregiving challenges that were unaddressed by advance directives are presented.

METHODS

Non-dominant simultaneous mixed-methods (QUAL-QUAN) were used to explore how end-of-life events influenced family caregivers. In-depth interviews were conducted with 108 caregivers about 4 months following the death of a family member who was in hospice care.

RESULTS

A majority (n = 90; 84.9%) had specific wishes about end-of-life treatment. Patients had a completed: Health Care Proxy-101 (93.3%); Living Will-43 (39.8%); Do Not Resuscitate orders (DNR)-82 (75.9%) and Medical Orders for Life Sustaining Treatment-40 (37%). A majority (n = 83; 76.9%) of caregivers said that they had "enough" or "just the right amount" of information to prepare for the patients' death. Five themes illustrated caregivers' experiences: Family Conflict; Patient/Family-Provider Conflict; Uncertainty, Caregiving Realities; Awareness-Avoidance of Dying.

CONCLUSION

A majority of had an advance directive, yet caregivers expressed feeling unprepared for decision-making, caregiving and discussing it with the dying person. The advance directive and care planning process fell short of providing needed communication, knowledge and preparation; it can be an opportunity for teaching, learning, preparing and supporting families at life's end.

Ethical and practical considerations for HIV cure-related research at the end-of-life: a qualitative interview and focus group study in the United States

BACKGROUND

One of the next frontiers in HIV research is focused on finding a cure. A new priority includes people with HIV (PWH) with non-AIDS terminal illnesses who are willing to donate their bodies at the end-of-life (EOL) to advance the search towards an HIV cure. We endeavored to understand perceptions of this research and to identify ethical and practical considerations relevant to implementing it.

METHODS

We conducted 20 in-depth interviews and 3 virtual focus groups among four types of key stakeholders in the United States (PWH, biomedical HIV cure researchers, HIV clinicians, and bioethicists) to obtain triangulated viewpoints because little was known about the ethics of this topic. Each group was queried as to ethical considerations, safeguards, and protections for conducting HIV cure-related research at the EOL to ensure this research remains acceptable.

RESULTS

All four key stakeholder groups generally supported HIV cure-related research conducted at the EOL because of the history of altruism within the PWH community and the potential for substantial scientific knowledge to be gained. Our informants expressed that: (1) Strong stakeholder and community involvement are integral to the ethical and effective implementation, as well as the social acceptability of this research; (2) PWH approaching the EOL should not inherently be considered a vulnerable class and their autonomy must be respected when choosing to participate in HIV cure-related research at the EOL; (3) Greater diversity among study participants, as well as multi-disciplinary research teams, is necessitated by HIV cure-related research at the EOL; (4) The sensitive nature of this research warrants robust oversight to ensure a favorable risk/benefit balance and to minimize the possibility of therapeutic misconception or undue influence; and (5) Research protocols should remain flexible to accommodate participants' comfort and needs at the EOL.

CONCLUSION

Because of the ethical issues presented by HIV cure-related research at the EOL, robust ethical safeguards are of utmost importance. The proposed ethical and practical considerations presented herein is a first step in determining the best way to maximize this research's impact and social value. More much inquiry will need to be directed towards understanding context-specific and cultural considerations for implementing EOL HIV cure research in diverse settings.

Social Model Hospice Home: A Concept Analysis

The term social model hospice first appeared late in the 20th century as a label for a complementary model to medical hospice care. Two decades later, the term is inconsistently defined and used by scholars, health care providers, public consumers, and those within the movement. The purpose of this review is to trace the development of the concept and confirm an evolving definition based on Rodgers' evolutionary method. Database and hand searching was done for the years 1975 to 2020, resulting in 25 publications for analysis. Unique antecedents include presence of a resource crisis, unmet needs falling outside the scope of medical hospice care, and desire to experience death outside the medical system and/or personal home. Attributes include a dedicated home, round-the-clock, individualized end-of-life care; care option when dying at home becomes unmanageable; collaboration with medical hospice services; nonprofit organization funded by community philanthropy; environment to support loved ones; and community volunteer involvement. Noted consequences are effective end-of-life care for dying patients and their families, innovative health care design, nationwide network of like-minded providers, and platform for end-of-life community education. Clarity of the concept will facilitate access to end-of-life care, further the model's development, formalize research endeavors, and foster community education.

"I want to go home": How location at death influences caregiver well-being in bereavement

OBJECTIVES

Goal concordant or congruent care involves having expressed wishes upheld. Yet, the preferred location for end-of-life care may be unaddressed. Caregiver-patient congruence between preferred and actual locations of care may influence the quality of life in bereavement. The study aimed to explore how the congruence between caregiver-patient preferred and actual locations of death influenced well-being in bereavement.

METHODS

Mixed methods were employed. In-depth in-person interviews were conducted with 108 bereaved caregivers of a hospice patient about 4 months after the death. An interview guide was used to collect quantitative and qualitative data: demographics, decision-making, Core Bereavement Items (CBI), Health Related Quality of Life, and perspectives on the end-of-life experiences. Data were analyzed with a convergent mixed methods one-phase process.

RESULTS

Patient preference-actual location congruence occurred for 53%; caregiver preference-actual location congruence occurred for 74%; caregiver-patient preference and location of death occurred for 48%. Participants who reported some type of incongruence demonstrated higher levels of distress, including more days of being physically and emotionally unwell and more intense bereavement symptoms. The Acute Separation subscale and CBI total scores demonstrated significant differences for participants who experienced incongruence compared with those who did not. Preference location congruence themes emerged: (1) caregiver-patient location congruence, (2) caregiver-patient location incongruence, and (3) location informed bereavement.

CONCLUSIONS

Congruence between a dying person's preferred and actual locations at death has been considered good care. There has been little focus on the reciprocity between caregiver-patient wishes. Discussing preferences about the place of end-stage care may not make location congruence possible, but it can foster shared understanding and support for caregivers' sense of coherence and well-being in bereavement.

Ethical and practical considerations for interventional HIV cure-related research at the end-of-life: A qualitative study with key stakeholders in the United States

Background

A unique window of opportunity currently exists to generate ethical and practical considerations presented by interventional HIV cure-related research at the end-of-life (EOL). Because participants would enroll in these studies for almost completely altruistic reasons, they are owed the highest ethical standards, safeguards, and protections. This qualitative empirical ethics study sought to identify ethical and practical considerations for interventional HIV cure-related research at the EOL.

Methods and findings

We conducted 20 in-depth interviews and three virtual focus groups (N = 36) with four key stakeholder groups in the United States: 1) bioethicists, 2) people with HIV, 3) HIV care providers, and 4) HIV cure researchers. This study produced six key themes to guide the ethical implementation of interventional HIV cure-related research at the EOL: 1) all stakeholder groups supported this research conditioned upon a clearly delineated respect for participant contribution and autonomy, participant understanding and comprehension of the risks associated with the specific intervention(s) to be tested, and broad community support for testing of the proposed intervention(s); 2) to ensure acceptable benefit-risk profiles, researchers should focus on limiting the risks of unintended effects and minimizing undue pain and suffering at the EOL; 3) only well-vetted interventions that are supported by solid pre-clinical data should be tested in the EOL translational research model; 4) the informed consent process must be robust and include process consent; 5) research protocols should be flexible and adopt a patient/participant centered approach to minimize burdens and ensure their overall comfort and safety; and 6) a participant’s next-of-kin/loved ones should be a major focus of EOL research but only if the participant consents to such involvement.

Conclusions

To our knowledge, this empirical ethics study generated the first ethical and practical considerations for interventional HIV cure-related research at the EOL. The ethical complexities of such research must be considered now. We must navigate this ethical conundrum so that we are good stewards of the participants’ extremely altruistic gifts by maximizing the impact and social value of this research. We hope that this study will serve as the foundation for future research and discussion on this topic.

Navigating the Transition from Advanced Illness to Bereavement: How Provider Communication Informs Family-related Roles and Needs

Person-centered, family-oriented services are integral to palliative and end-of-life care. Effective communication with providers informs the quality of the dying experience for patients and how families fare in bereavement. This paper reports findings from a study exploring how communication and care in the later stages of an advanced illness influence family caregivers' well-being in bereavement. A concurrent triangulation design was used to analyze data collected during semi-structured interviews with 108 recently bereaved caregivers from a single hospice agency in Western New York. Findings from this study suggest that family caregivers assume the role of interpreter and advocate while engaged in both formal and informal communication with health care providers at the end of care-recipients' lives. Findings also suggest that families are more likely to feel emotionally prepared for loss and grief when health care providers are available to communicate in a concise, consistent, and compassionate manner. The results illuminate the important connection between communication during the transition from late-stage illness to end-of-life care and preparation for bereavement. The paper concludes with a discussion of how findings from this study align with recent concerted efforts to establish standards and competencies for social work education and practice in palliative care.

End-of-life experience for older adults in Ireland: results from the Irish longitudinal study on ageing (TILDA)

BACKGROUND

End-of-life experience is a subject of significant policy interest. National longitudinal studies offer valuable opportunities to examine individual-level experiences. Ireland is an international leader in palliative and end-of-life care rankings. We aimed to describe the prevalence of modifiable problems (pain, falls, depression) in Ireland, and to evaluate associations with place of death, healthcare utilisation, and formal and informal costs in the last year of life.

METHODS

The Irish Longitudinal Study on Ageing (TILDA) is a nationally representative sample of over-50-year-olds, recruited in Wave 1 (2009-2010) and participating in biannual assessment. In the event of a participant's death, TILDA approaches a close relative or friend to complete a voluntary interview on end-of-life experience. We evaluated associations using multinomial logistic regression for place of death, ordinary least squares for utilisation, and generalised linear models for costs. We identified 14 independent variables for regressions from a rich set of potential predictors. Of 516 confirmed deaths between Waves 1 and 3, the analytic sample contained 375 (73%) decedents for whom proxies completed an interview.

RESULTS

There was high prevalence of modifiable problems pain (50%), depression (45%) and falls (41%). Those with a cancer diagnosis were more likely to die at home (relative risk ratio: 2.5; 95% CI: 1.3-4.8) or in an inpatient hospice (10.2; 2.7-39.2) than those without. Place of death and patterns of health care use were determined not only by clinical need, but other factors including age and household structure. Unpaid care accounted for 37% of all care received but access to this care, as well as place of death, may be adversely affected by living alone or in a rural area. Deficits in unpaid care are not balanced by higher formal care use.

CONCLUSIONS

Despite Ireland's well-established palliative care services, clinical need is not the sole determinant of end-of-life experience. Cancer diagnosis and access to family supports were additional key determinants. Future policy reforms should revisit persistent inequities by diagnosis, which may be mitigated through comprehensive geriatric assessment in hospitals. Further consideration of policies to support unpaid carers is also warranted.

Population-based palliative care planning in Ireland: how many people will live and die with serious illness to 2046?

Background: All countries face growing demand for palliative care services.  Projections of need are essential to plan care in an era of demographic change.   We aim to estimate palliative care needs in the Republic of Ireland from 2016 to 2046. Methods: Static modelling of secondary data.  First, we estimate the numbers of people who will die from a disease associated with palliative care need.  We combine government statistics on cause of death (2007-2015) and projected mortality (2016-2046).  Second, we combine these statistics with survey data to estimate numbers of people aged 50+ living and dying with diseases associated with palliative care need.  Third, we use these projections and survey data to estimate disability burden, pain prevalence and health care utilisation among people aged 50+ living and dying with serious medical illness. Results: In 2016, the number of people dying annually from a disease indicating palliative care need was estimated as 22,806, and the number of people not in the last year of life aged 50+ with a relevant diagnosis was estimated as 290,185.  Equivalent estimates for 2046 are up to 40,355 and 548,105, increases of 84% and 89% respectively.  These groups account disproportionately for disability burden, pain prevalence and health care use among older people, meaning that population health burdens and health care use will increase significantly in the next three decades. Conclusion: The global population is ageing, although significant differences in intensity of ageing can be seen between countries. Prevalence of palliative care need will nearly double over 30 years, reflecting Ireland’s relatively young population.  Older people living with a serious disease outnumber those in the last year of life by approximately 12:1, necessitating implementation of integrated palliative care across the disease trajectory. Urgent steps on funding, workforce development and service provision are required to address these challenges.

Do Caregiver Experiences Shape End-of-Life Care Perceptions? Burden, Benefits, and Care Quality Assessment

CONTEXT

Researchers, hospices, and government agencies administer standardized questionnaires to caregivers for assessing end-of-life care quality. Caregiving experiences may influence end-of-life care quality reports, which have implications for caregiver outcomes, and are a clinical and policy priority.

OBJECTIVES

This study aims to determine whether and how caregivers' end-of-life care assessments depend on their burden and benefit perceptions.

METHODS

This study analyzes data from 391 caregivers in the 2011 National Study of Caregiving and their Medicare beneficiary care recipients from the 2011-2016 National Health and Aging Trends Study. Caregivers assessed five end-of-life care aspects for decedents. Logistic regression was used and predicted probabilities of caregivers positively or negatively assessing end-of-life care based on their burden and benefit experiences calculated. Analyses adjusted for caregiver and care recipient demographic and health characteristics.

RESULTS

No or minimal caregiving burden is associated with ≥0.70 probability of caregivers reporting they were always informed about the recipient's condition and that the dying person's care needs were always met, regardless of perceived benefits. High perceived caregiving benefit is associated with ≥0.80 probability of giving such reports, even when perceiving high burden.

CONCLUSION

Caregiver burden and benefit operate alongside one another regarding two end-of-life care evaluations, even when years elapse between caregiver experience reports and care recipient death. This suggests that caregiver interventions reducing burden and bolstering benefits may have a positive and lasting impact on end-of-life care assessments.

Outcomes of clinical ethics support near the end of life: A systematic review

BACKGROUND

Clinical ethics support services have been advocated in recent decades. In clinical practice, clinical ethics support services are often requested for difficult decisions near the end of life. However, their contribution to improving healthcare has been questioned and demands for evaluation have been put forward. Research indicates that there are considerable challenges associated with defining adequate outcomes for clinical ethics support services. In this systematic review, we report findings of qualitative studies and surveys, which have been conducted to evaluate clinical ethics support services near the end of life.

METHODS

Electronic databases and other sources were queried from 1970 to May 2018. Two authors screened studies independently. Methodological quality of studies was assessed. For each arm of the review, an individual synthesis was performed. Prospero ID: CRD42016036241.

ETHICAL CONSIDERATIONS

Ethical approval is not needed as it is a systematic review of published literature.

RESULTS

In all, 2088 hits on surveys and 2786 on qualitative studies were found. After screening, nine surveys and four qualitative studies were included. Survey studies report overall positive findings using a very wide and heterogeneous range of outcomes. Negative results were reported only occasionally. However, methodological quality and conceptual justification of used outcomes was often weak and limits generalizability of results.

CONCLUSION

Evidence points to positive outcomes of clinical ethics support services. However, methodological quality needs to be improved. Further qualitative or mixed-method research on evaluating clinical ethics support services may contribute to the development of evaluating outcomes of clinical ethics support services by means of broaden the range of appropriate (process-oriented) outcomes of (different types of) clinical ethics support services.

Unintended Harm? Race Differences in the Relationship Between Advance Care Planning and Psychological Distress at the End of Life

CONTEXT

Research has revealed racial disparities in advance care planning and intensity of end-of-life care. Studies of the relationship between advance care planning and sadness and anxiety at the end of life are inconclusive.

OBJECTIVES

The objective of this study was to determine the extent to which the relationship between advance care planning and sadness and anxiety at the end of life differs by race.

METHODS

This study analyzes data from 315 Medicare beneficiaries from the 2011-2016 National Health and Aging Trends Study. Caregiver-assessed sadness/anxiety at decedent's end of life was categorized as none, managed needs, and unmanaged needs. We used multinomial logistic regression and calculated relative risk and predicted probability of reporting sadness/anxiety by race and advance care planning status, controlling for demographic and health characteristics.

RESULTS

Among non-Hispanic black/African-Americans who died, end-of-life discussions and having a health care proxy increased the predicted probability of caregivers reporting unmanaged needs related to sadness/anxiety by factors of 2.6 and 3.5, respectively (discussions: from 15% to 39%, P = 0.03; health care proxy: from 12% to 42%, P = 0.008). By contrast, among non-Hispanic white decedents, end-of-life discussions and naming a health care proxy were not associated with caregivers reporting unmanaged needs related to sadness/anxiety.

CONCLUSION

Advance care planning may not work the same way for black and white individuals. End-of-life discussions and naming a health care proxy are potentially harmful to dying black patients' mental health. This finding suggests a need for additional research to understand why caregivers report unmanaged sadness/anxiety for dying black patients who engaged in advance care planning and increased attention to these patients' mental health at the end of life.

Ethical considerations for HIV cure-related research at the end of life

Background

The U.S. National Institute of Allergies and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH) have a new research priority: inclusion of terminally ill persons living with HIV (PLWHIV) in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego (UCSD) for PLWHIV who have a terminal illness, with a prognosis of less than 6 months.

Discussion

As end-of-life (EOL) HIV cure research is relatively new, the scientific community has a timely opportunity to examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders (biomedical researchers, PLWHIV, bioethicists, and socio-behavioral scientists) and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders.

Conclusion

EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable.

Application of Community-Based Participatory Research Methods to a Study of Complementary Medicine Interventions at End of Life

Community-based participatory research (CBPR) principles can be successfully applied to the design and implementation of a complementary medicine study for adults with end-stage AIDS. The Yale Prevention Research Center partnered with Leeway, Inc., an AIDS-dedicated nursing facility, and other academic and clinical entities to conduct a randomized, controlled pilot trial of meditation and massage on quality of life at the end of life. Using CBPR principles, a methodology was developed that was scientifically rigorous, highly respectful, and acceptable to the 91% minority study population. Using continuous, open communication among all involved parties, challenges were satisfactorily addressed in a timely manner. Fifty-eight residents (97% of those eligible) with end-stage AIDS participated from November 2001 to September 2003. Subjects received 1-month interventions of meditation, massage, combined meditation and massage, or standard care. The study of quality-of-life in end-stage AIDS poses unique challenges well met by applying CBPR principles to an academic-community research partnership.

Socioeconomic Differentials in Mortality Among the Oldest Old in China

Although an inverse relationship between socioeconomic status (SES) and mortality has been well documented for many populations throughout the world, it remains unclear whether this relationship holds true for the oldest old. Most notably, some scholars have suggested that the relationship may disappear at the oldest ages. Using data from the 1998, 2000, and 2002 waves of the Chinese Longitudinal Healthy Longevity Survey, this study examined the relationship between SES and mortality among the oldest old (80 years and older) population in China. The results show the continuing prevalence of SES differentials in mortality—higher SES is significantly associated with lower mortality risks—among the oldest old in China. The authors further show that the relationship holds regardless of how the oldest old are operationalized (as 80 years and older, 90 years and older, or 100 years and older).

Trajectories of ADL Disability Among Community-Dwelling Frail Older Persons

This study examines how activity of daily living (ADL) disability of community-living frail elders changes in a two-year period and how the pattern of change varies between those who subsequently died or were institutionalized and those who continued to live in the community. Multiple waves of data from a cohort of older participants ( N = 3,161) in Michigan’s Medicaid Waiver Program were analyzed using the hierarchical linear modeling (HLM) approach. The results suggest that changes in ADL disability were nonlinear and the pattern of change varied by their subsequent status. Participants who subsequently died or were institutionalized exhibited a steep increase in ADL disability during the last few months before the events, whereas continued community residents were relatively stable in ADL disability during the two-year study period. Within each group, substantial individual variation in ADL disability trajectories exists. Implications of the findings to research and practice are discussed.

Is It the Difference a Day Makes? Bereaved Caregivers' Perceptions of Short Hospice Enrollment

CONTEXT

Hospice enrollment for less than one month has been considered too late by some caregivers and at the right time for others. Perceptions of the appropriate time for hospice enrollment in cancer are not well understood.

OBJECTIVES

The objectives of the study were to identify contributing factors of hospice utilization in cancer for ≤7 days, to describe and compare caregivers' perceptions of this as "too late" or at the "right time."

METHODS

Semistructured, in-depth, in-person interviews were conducted with a sample subgroup of 45 bereaved caregivers of people who died from cancer within seven days of hospice enrollment. Interviews were transcribed and entered into Atlas.ti for coding. Data were grouped by participants' perceptions of the enrollment as "right time" or "too late."

RESULTS

Overall, the mean length of enrollment was MLOE = 3.77 (SD = 1.8) days and ranged from three hours to seven days. The "right time" group (N = 25 [56%]) had a MLOE = 4.28 (SD = 1.7) days. The "too late" group (N = 20 [44%]) had a MLOE = 3.06 (SD = 1.03) days. The difference was statistically significant (P = 0.029). Precipitating factors included: late-stage diagnosis, continuing treatment, avoidance, inadequate preparation, and systems barriers. The "right time" experience was characterized by: perceived comfort, family needs were met, preparedness for death. The "too late" experience was characterized by perceived suffering, unprepared for death, and death was abrupt.

CONCLUSION

The findings suggest that one more day of hospice care may increase perceived comfort, symptom management, and decreased suffering and signal the need for rapid response protocols.

Palliative care and nursing in dissertations and theses in Portugal: a bibliometric study

Abstract Objective To identify the academic scientific production on palliative care in master dissertations and PhD theses carried out by nurses in Portugal. Method A descriptive retrospective study of bibliometric type with search for the abstracts available in repositories of higher education institutions in the period 2000-2014. Results Of the 1814 papers identified, 249 met the inclusion criteria (ten doctoral theses and 239 master dissertations). The most representative methodological approach was quantitative (31.35%) and the most studied area was family/informal caregiver (20.69%). The most studied target population were the students/health professionals (38.51%). Conclusion The academic scientific production in this area has been growing in spite of the need for continued investment in order to fill the identified gaps.

Family Caregivers' Pain Management in End-of-Life Care: A Systematic Review

CONTEXT

Pain management was the most identified burden faced by family caregivers in end-of-life caregiving.

OBJECTIVES

To synthesize current scientific evidence on family caregivers' experience of pain management in end-of-life care.

METHODS

A systematic review was conducted using CINAHL, Embase, PubMed, and Cochrane Library electronic databases. Data were extracted from each included paper and organized into tables to synthesize the findings.

RESULTS

Fourteen research papers focusing on family caregivers' experience of pain management and strategies in end-of-life care were included. Nine were observational studies, 3 were case studies, and 2 were experimental studies. These studies mainly focused on exploring family caregivers' engagement in pain management and communication with the hospice care team about pain control; family caregivers' knowledge, skills, and self-efficacy in pain management; and family caregivers' concerns and experience of pain management.

CONCLUSION

This review identified themes similar to previous reviews on family caregivers of patients with cancer or in palliative care: inadequate knowledge and assessment skills in pain management, misunderstanding of pain medications, and poor communication with the care team. Future research should design educational programs and material for family caregivers to improve their pain management knowledge and skills, communication, and engagement in care. The scientific knowledge on this topic is scarce, and level of evidence is low; it is therefore imperative to have more exploratory studies to expand the quality and quantity of evidence and increase our understanding of family caregivers' needs and barriers to pain management based on larger and more diverse patient and caregiver samples.

Live Discharge from Hospice and the Grief Experience of Dementia Caregivers

When an individual has dementia, family members are involved in many care transitions in their roles as caregivers. One such transition is the 'live' discharge from hospice services. This occurs when an individual no longer meets eligibility criteria. This can be difficult for caregivers who have been anticipating an end to understand in the context of their grief process. This qualitative study (N = 24) explored the experience of caregivers of adults with dementia, including Alzheimer's disease, who experienced a 'live' discharge from hospice. Specifically, the experience of grief is examined. Results from this study highlight the complexity of caring for someone with a terminal disease and the grief experience in end-of-life care as caregivers struggle to understand the individual's terminal prognosis as temporary. This is further complicated for caregivers who must resume caregiving responsibilities or assume a new caregiving role after experiencing a loss of hospice services. Finally, hospice social workers are well positioned to offer emotional and other concrete support to caregivers who experience a 'live' discharge.

Te Pākeketanga: living and dying in advanced age--a study protocol

BACKGROUND

The number of people dying in advanced old age is increasing rapidly and building the evidence base regarding end - of - life care for older people has been identified as an international policy priority. The unique opportunity to link longitudinal studies of ageing with studies exploring the end of life circumstances of older people remains under-exploited internationally. Very little is known about the specific circumstances, cultural needs and care preferences of indigenous older people, including Māori, at end - of - life and the needs of their whānau/ extended family carers.

METHODS

We will use rigorous qualitative methods to conduct post-bereavement interviews with bereaved whānau and family of 50-60 people who died >80 years; approximately half of participants will be Maori. The older decedents were participants in the first longitudinal study of older people involving a specific indigenous cohort internationally: Te Puāwaitanga O Ngā Tapuwae Kia Ora Tonu, Life and Living in Advanced Age: a Cohort Study in New Zealand (LiLACS NZ). Prior to death, they completed a questionnaire regarding their end-of-life preferences and nominated a family or whānau member to participate in this separate study exploring end-of-life circumstances of those in advanced age.

DISCUSSION

Recommendations to improve care will be formulated in collaboration with participants and their local hapū (sub-tribe). Ultimately this study has the potential to inform better outcomes for the growing numbers of people dying in advanced old age both in New Zealand and internationally, as well as their whānau and family caregivers. It also highlights the ability to generate an in-depth understanding of end-of-life circumstances by appending studies of palliative and end-of-life care onto existing longitudinal studies.

Future Time Perspective and End-of-Life Planning in Older Adults

This study explores the extent to which cognitive processes, specifically perceptions of one’s distance to death, are associated with informal and formal advance care planning (ACP) in a sample of older adults. Data come from the New Jersey End-of-Life (EOL) study, a survey of 305 adults aged 55–91. Binary logistic regression models evaluate the odds that someone conducted ACP. Persons who perceive remaining life span to be expansive or limited have significantly lower odds of formally planning for the EOL, relative to those in the middle category. Death anxiety and having a family confidante partially explain these associations. The association between future time perspective (FTP) and discussions is not statistically significant. Practitioners may consider individuals’ FTPs when discussing preferences for EOL medical care.

Measuring intensity of end of life care: a systematic review

Background

Many studies have measured the intensity of end of life care. However, no summary of the measures used in the field is currently available.

Objectives

To summarise features, characteristics of use and reported validity of measures used for evaluating intensity of end of life care.

Methods

This was a systematic review according to PRISMA guidelines. We performed a comprehensive literature search in Ovid Medline, Embase, The Cochrane Library of Systematic Reviews and reference lists published between 1990-2014. Two reviewers independently screened titles, abstracts, full texts and extracted data. Studies were eligible if they used a measure of end of life care intensity, defined as all quantifiable measures describing the type and intensity of medical care administered during the last year of life.

Results

A total of 58 of 1590 potentially eligible studies met our inclusion criteria and were included. The most commonly reported measures were hospitalizations (n = 44), intensive care unit admissions (n = 39) and chemotherapy use (n = 27). Studies measured intensity of care in different timeframes ranging from 48 hours to 12 months. The majority of studies were conducted in cancer patients (n = 31). Only 4 studies included information on validation of the measures used. None evaluated construct validity, while 3 studies considered criterion and 1 study reported both content and criterion validity.

Conclusions

This review provides a synthesis to aid in choosing intensity of end of life care measures based on their previous use but simultaneously highlights the crucial need for more validation studies and consensus in the field.

Measuring the quality of dying and death in the pediatric intensive care setting: the clinician PICU-QODD

CONTEXT

In the pediatric intensive care setting, an accurate measure of the dying and death experience holds promise for illuminating how critical care nurses, physicians, and allied psychosocial staff can better manage end-of-life care for the benefit of children and their families, as well as the caregivers.

OBJECTIVES

The aim was to assess the reliability and validity of a clinician measure of the quality of dying and death (Pediatric Intensive Care Unit-Quality of Dying and Death 20 [PICU-QODD-20]) in the pediatric intensive care setting.

METHODS

In a retrospective cohort study, five types of clinicians (primary nurse, bedside nurse, attending physician, and the psychosocial clinician and critical care fellow most involved in the case) were asked to complete a survey for each of the 94 children who died over a 12 month period in the pediatric intensive care units of two children's hospitals in the northeast U.S. Analyses were conducted within type of clinician.

RESULTS

In total, 300 surveys were completed by 159 clinicians. Standard item analyses and substantive review led to the selection of 20 items for inclusion in the PICU-QODD-20. Cronbach alpha for the PICU-QODD-20 ranged from 0.891 for bedside nurses to 0.959 for attending physicians. For each type of clinician, the PICU-QODD-20 was significantly correlated with the quality of end-of-life care and with meeting the family's needs. In addition, when patient/family or team barriers were encountered, the PICU-QODD-20 score tended to be significantly lower than for cases in which the barrier was not encountered.

CONCLUSION

The PICU-QODD-20 shows promise as a valid and reliable measure of the quality of dying and death in pediatric intensive care.

End-of-Life Family Caregiving for Older Parents in China’s Rural Anhui Province

Cette étude a examiné les corrélats de la prestation de soins de la fin de vie fournis par les enfants adultes à leurs parents âgés et le rôle du sexe des enfants adultes en soins familiaux dans la Chine rurale. Les données proviennent de cinq vagues de l'Étude longitudinale du bien-être des personnes âgées en milieu rural dans la province de l'Anhui, en Chine, pendant 12 ans, et d'une enquête post-mortalité. On a utilisé la modélisation linéaire hiérarchique . Les résultats ont montré que l'ordre de naissance des enfants adultes, la distance géographique antérieure, et l'échange du soutien intergénérationnel antérieur étaient significativement associés à la prestation de soins de famille de la fin de vie. Les enfants les plus âgés, par rapport à d'autres frères et sœurs, fourni les plus grand soins de fin de vie pour leurs parents. Les enfants qui cohabitent avec les parents plus âgés avant leur mort, par rapport à d'autres enfants des mêmes parents, ont offert les plus grands soins. Les enfants adultes qui avaient déjà échangé le soutien instrumental avec les parents âgés avant la mort, en particulier les fils, tendaient à fournir le plus grands soins en fin de vie, par rapport à ceux d'autres.

Feasibility of assessing quality of care at the end of life in two cluster trials using an after-death approach with multiple assessments

BACKGROUND

In 2009 two randomised cluster trials took place to assess the introduction of the Italian Version of the Liverpool Care Pathway in hospitals and hospices. Before and after data were gathered. The primary aim of this study is to evaluate the feasibility of using a combination of assessment methods aimed at different proxy respondents to create a means of measuring quality of care at the end of life. We also aim to explore whether there are differences in response to this approach between the hospice and hospital inpatient settings.

METHODS

A retrospective design was used. Eligible deaths were traced through death registries, and proxies were used to give information. Four procedures of assessment were used to measure different dimensions. Feasibility was assessed through compliance and adherence to the study instruments, and measured against standards derived from previous after-death studies. The proxy caregiver's rating of the study tools was also measured, to gauge feasibility and effectiveness. All consecutive cancer deaths that occurred in the study period were eligible. In both trials, deaths were excluded if the patient was a relative of hospital/hospice staff. 145 patients were recruited from the Hospital setting, and 127 from Hospice.

RESULTS

A high proportion of non-professional caregivers were interviewed - in both hospital (76.6%) and hospice (74.8%). There was no significant difference in the median number of days in each setting. 89.0% of hospital patients' GPs and 85.0% of hospice patients' GPs were interviewed. Care procedures were recorded in all hospice cases, and were missing in only 1 hospital case.52.7% of Hospital patients' relatives and 64.12% Hospice relatives were assessed to have been caused a low level of distress through the study.

CONCLUSIONS

The data shows high levels of compliance and adherence to the study instruments. This suggests that this approach to assessing quality of care is feasible, and this coupled with low levels of distress caused by the study instruments suggest effectiveness. There were no substantial differences between the hospice and hospital settings.

Acute hospital-based services utilisation during the last year of life in New South Wales, Australia: methods for a population-based study

OBJECTIVES

The aim of this study is to describe healthcare utilisation in the last year of life for people in Australia, to help inform health services planning. The methods and datasets that are being used are described in this paper.

DESIGN/SETTING

Linked, routinely collected administrative health data are being analysed for all people who died in New South Wales (NSW), Australia's most populous state, in 2007. The data comprised linked death records (2007), hospital admissions and emergency department presentations (2006-2007) and cancer registrations (1994-2007).

PARTICIPANTS

There were 46 341 deaths in NSW in 2007. The initial analyses include 45 760 decedents aged 18 years and over.

OUTCOME MEASURES

The primary measures address the utilisation of hospital-based services at the end of life, including number and length of hospital admissions, emergency department presentations, intensive care admissions, palliative-related admissions and place of death.

RESULTS

The median age at death was 80 years. Cause of death was available for 95% of decedents and 85% were linked to a hospital admission record. In the greater metropolitan area, where data capture was complete, 83% of decedents were linked to an emergency department presentation. 38% of decedents were linked to a cancer diagnosis in 1994-2007. The most common causes of death were diseases of the circulatory system (34%) and neoplasms (29%).

CONCLUSIONS

This study is among the first in Australia to give an information-rich census of end-of-life hospital-based experiences. While the administrative datasets have some limitations, these population-wide data can provide a foundation to enable further exploration of needs and barriers in relation to care. They also serve to inform the development of a relatively inexpensive, timely and reliable approach to the ongoing monitoring of acute hospital-based care utilisation near the end of life and inform whether service access and care are optimised.

Modelling the landscape of palliative care for people with dementia: a European mixed methods study

BACKGROUND

Palliative care for people with dementia is often sub-optimal. This is partly because of the challenging nature of dementia itself, and partly because of system failings that are particularly salient in primary care and community services. There is a need to systematize palliative care for people with dementia, to clarify where changes in practice could be made.To develop a model of palliative care for people with dementia that captures commonalities and differences across Europe, a technology development approach was adopted, using mixed methods including 1) critical synthesis of the research literature and policy documents, 2) interviews with national experts in policy, service organisation, service delivery, patient and carer interests, and research in palliative care, and 3) nominal groups of researchers tasked with synthesising data and modelling palliative care.

DISCUSSION

A generic model of palliative care, into which quality indicators can be embedded. The proposed model includes features deemed important for the systematisation of palliative care for people with dementia. These are: the division of labour amongst practitioners of different disciplines; the structure and function of care planning; the management of rising risk and increasing complexity; boundaries between disease-modifying treatment and palliative care and between palliative and end-of-life care; and the process of bereavement.

SUMMARY

The co-design approach to developing a generic model of palliative care for people with dementia has placed the person needing palliative care within a landscape of services and professional disciplines. This model will be explored further in the intervention phase of the IMPACT project.

'Peace' and 'life worthwhile' as measures of spiritual well-being in African palliative care: a mixed-methods study

Background

Patients with incurable, progressive disease receiving palliative care in sub-Saharan Africa experience high levels of spiritual distress with a detrimental impact on their quality of life. Locally validated measurement tools are needed to identify patients’ spiritual needs and evaluate and improve spiritual care, but up to now such tools have been lacking in Africa. The African Palliative Care Association (APCA) African Palliative Outcome Scale (POS) contains two items relating to peace and life worthwhile. We aimed to determine the content and construct validity of these items as measures of spiritual wellbeing in African palliative care populations.

Methods

The study was conducted at five palliative care services, four in South Africa and one in Uganda. The mixed-methods study design involved: (1) cognitive interviews with 72 patients, analysed thematically to explore the items’ content validity, and (2) quantitative data collection (n = 285 patients) using the POS and the Spirit 8 to assess construct validity.

Results

(1) Peace was interpreted according to the themes ‘perception of self and world’, ‘relationship to others’, ‘spiritual beliefs’ and ‘health and healthcare’. Life worthwhile was interpreted in relation to ‘perception of self and world’, ‘relationship to others’ and ‘identity’. (2) Conceptual convergence and divergence were also evident in the quantitative data: there was moderate correlation between peace and Spirit 8 spiritual well-being (r = 0.46), but little correlation between life worthwhile and Spirit 8 spiritual well-being (r = 0.18) (both p < 0.001). Correlations with Spirit 8 items were weak to moderate.

Conclusions

Findings demonstrate the utility of POS items peace and life worthwhile as distinct but related measures of spiritual well-being in African palliative care. Peace and life worthwhile are brief and simple enough to be integrated into routine practice and can be used to measure this important but neglected outcome in this population.

How to analyze palliative care outcome data for patients in Sub-Saharan Africa: an international, multicenter, factor analytic examination of the APCA African POS

CONTEXT

The incidence of life-limiting progressive disease in sub-Saharan Africa presents a significant clinical and public health challenge. The ability to easily measure patient outcomes is essential to improving care.

OBJECTIVES

The present study aims to determine the specific factors (if any) that underpin the African Palliative Care Association African Palliative Outcome Scale to assist the analysis of data in routine clinical care and audit.

METHODS

Using self-reported data collected from patients with HIV infection in eastern and southern Africa, an exploratory factor analysis was undertaken with 1337 patients; subsequently, a confirmatory analysis was done on two samples from separate data sets (n = 445).

RESULTS

Using exploratory factor analysis initially, both two- and three-factor solutions were examined and found to meet the criteria for simple structure and be readily interpretable. Then using confirmatory factor analysis on two separate samples, the three-factor solution demonstrated better fit, with Goodness-of-Fit Index values greater than 0.95 and Normative Fit Index values close to 0.90. The resulting three factors were 1) physical and psychological well-being, 2) interpersonal well-being, and 3) existential well-being.

CONCLUSION

This analysis presents an important new opportunity in the analysis of outcome data for patients with progressive disease. It has advantages over both the total scoring of multidimensional scaling (which masks differences between domains) and of item scoring (which requires repeated analyses). The three factors map well onto the underlying concept and clinical goals of palliative care, and will enable audit of facility care.

Defining the palliative care patient: a systematic review

BACKGROUND

The lack of a clear definition of the palliative care patient hampers the comparison of results across different studies and impedes implementation of research findings in everyday practice.

AIM

The aim of this article is to propose minimum characteristics that define a palliative care patient.

DESIGN

The design involved a systematic review of medical literature searching randomised controlled trials (RCTs) in palliative care for clear descriptions of their palliative care patients. We systematically describe relevant characteristics of the study populations of 60 eligible RCTs.

DATA SOURCES

The data sources used were MEDLINE, EMBASE, CINAHL, and PSYCHINFO, including all non-cancer RCTs (1 January 1995-4 March 2010) and an equivalent number of the most recent cancer RCTs (1 January 2003-4 March 2010).

RESULTS

Half of the non-cancer studies were excluded because they did not relate to palliative care. We conclude that published RCTs have no clear definitions of their palliative care patients and illustrate the diversity of this patient, the lack of consensus concerning the attributes of illnesses needing palliation and the ambiguous use of the adjective 'palliative'.

CONCLUSIONS

We propose elements of the patients' health status (e.g. a progressive, life-threatening disease with no possibility of obtaining remission or stabilisation, or modifying the course of the illness) and the care delivered to them (e.g. a holistic interdisciplinary approach that focuses on supporting the quality of the end of life) to be included in the definition of a palliative care patient. We also suggest considering the patients' readiness to accept palliative care and a vision of palliative care shared by the patient and all caregivers involved as potentially important elements in this definition.

Pain among ambulatory HIV/AIDS patients: multicenter study of prevalence, intensity, associated factors, and effect

This study aimed to determine the prevalence, intensity, associated factors, and effect of pain among ambulatory HIV/AIDS patients. Three-hundred two adult ambulatory HIV/AIDS patients were consecutively recruited from HIV/AIDS outpatient clinics at 2 teaching hospitals in Uganda. The presence and intensity of pain were self-reported using the Brief Pain Inventory (BPI); symptom data were collected using the Memorial Symptom Assessment Scale (MSAS-SF); and quality of life (QOL) was assessed using the Medical Outcome Scale-HIV. Forty-seven percent reported pain in the 7 days prior to the survey and pain was a symptom at the time of diagnosis for 68%. On the 0 to 10 numeric scale, 53% reported mild pain (1-4 rating), 20% reported moderate pain (5-6 rating) while 27% reported severe pain (7-10 rating). Gender was not associated with pain intensity, but reduced functional performance, increasing number of symptoms, advanced HIV disease , physical symptom distress (MSAS-SF), and number of health comorbidities were significantly associated with pain intensity (P < .04). Increasing pain intensity was associated with greater functional ability impairment (BPI functional interference index) and poorer QOL. Pain is a common symptom among ambulatory HIV/AIDS patients and has a debilitating effect on QOL. There is a significant unmet need for pain relief in the population.

PERSPECTIVE

This article discusses the characteristics and effect of pain on function and QOL in East African patients. It also contributes information on characteristics of HIV/AIDS adult patients in the East Africa demonstrating the aspects in which pain is similar across different cultures.

Honoring patient care preferences: surrogates speak

A growing body of evidence has pointed to the stressful experience surrounding surrogate decision-making on behalf of incapacitated patients. This study (N = 59) asked surrogates to speak about their experiences immediately after having made a life-sustaining treatment decision. Grounded theory analysis revealed four themes: (1) the emotional impact of the decision-making process on the surrogate; (2) the difficulty of watching a loved one's health deteriorate; (3) the importance of having a Living Will (LW) or other written/verbal instructions; and (4) the reliance on spirituality as a means of coping with the surrogate experience. Findings of this study suggest that engaging surrogates at the time of patient admission may be essential in order to clarify patient preferences and strengthen communication between surrogates and the interdisciplinary healthcare team.

Knowledge, attitudes, experiences, and confidence of nurses in completing advance directives: a systematic synthesis of three studies

BACKGROUND

Advance directives (ADs) are one of the few means for patients to indicate their end-of-life (EOL) treatment option preference. An effective and consistent solution for increasing the AD completion rate remains elusive. A literature search revealed three studies completed in the United States that employed an identical methodology and focused on registered nurses (RNs). These studies examined a variety of concepts, including nurses' knowledge, attitudes, experience, and confidence with regard to ADs.

PURPOSE

This review completed a systematic synthesis of reported results from three survey studies that focused, respectively, on oncology, critical care, and emergency RNs who were members of various professional nursing organizations.

METHODS

Our investigation addressed the following research questions: What are the knowledge, attitudes, experience, and confidence of RNs with regard to ADs, and what is the relationship among these study variables? Each study used the Knowledge, Attitudes, and Experiential Survey on Advance Directives Instrument to obtain findings.

RESULTS

Findings indicated that level of knowledge of nurses was about 60% correct and that nurses reported a moderate level of confidence related to ADs. Nurses stated they were experienced in AD discussions and agreed with attitude statements indicating support of ADs. Advocacy was a theme in the findings of these studies, as most nurses agreed with the statement that nurses should uphold patients' wishes. Time was identified as an impediment to AD completion. Critical care nurses had higher levels of awareness of ADs, as compared with oncology and emergency room nurses, although the cause of this difference is unclear. Although RNs provided AD education and explanations and described the various types of EOL care, these study subjects suggested that discussions of patients' prognoses may be an intervention more appropriate for nurses or other clinicians with advanced education and training. CONCLUSION/LIMITATIONS: The low Cronbach's alpha values in the attitude scales within the survey instrument posed limitations in the original research on the use of attitude scale scores in statistical analysis. The data examined in this study was obtained from published reports, which limited the synthesis and analysis of study findings. Nurses need to refine their role in AD discussions with patients. End-of-life discussions should be an interwoven process between RNs and the multidisciplinary team.

Palliative care research in Latin America and the Caribbean: from the beginning to the Declaration of Venice and beyond

BACKGROUND

Research in palliative care has increased significantly in the last decade, while the vast majority of the global disease burden occurs in developing countries.

AIMS

To explore the palliative care research activity in Latin America and the Caribbean (LAC) and its visibility in the international palliative care literature, with a special focus on research studies.

METHODS

A bibliometric analysis was conducted in MEDLINE(®), Embase(®), PsycINFO(®), and CINAHL(®). Inclusion criteria were: (1) articles published in peer-reviewed scientific journals; (2) main subject was palliative care; (3) research study; (4) the first author or coauthors was based in LAC; and/or (5) the data collected derived from LAC.

RESULTS

One hundred six articles from 10 countries were identified in the literature research. The first publication dates from 1989 and was a qualitative study in Brazil. This study shows a modest contribution of publications from LAC. However, the volume of publications within the region is distributed unequally, reflecting the heterogeneity of the region: Brazil published more than half of the articles, while 35 countries have no publications. Most of the studies were quantitative research, predominantly cross-sectional studies. Qualitative studies often used interviews. Health care service was the most researched issue. Seventy percent of studies were carried out in institutions.

CONCLUSIONS

Palliative care research should have a place in LAC. The development of a regional research agenda tailored to the needs and features of the region considering the health care structure and local resources available is indispensable.

Quality of care and quality of dying in nursing homes: two measurement models

BACKGROUND

There is consistent evidence of significant variation in the quality of end-of-life care among nursing homes, with many facilities ill-prepared to provide optimal physical and psychological care that is culturally sensitive and respectful of the needs and preferences of residents and their family members. There is continued evidence that what is impeding efforts to improve care is that most measurement tools are hampered by a lack of distinction between quality of care and quality of dying as well as a lack of complete psychometric evaluation. Further, health services researchers cite the need to include "system-level" factors, variables that reflect leadership, culture, or informal practices, all of which influence end-of-life care and can be used to differentiate one setting from another. The purpose of this article is to report advancement in conceptualizing quality end-of-life care in nursing homes and to offer a refined approach to measurement.

METHODS

Two latent constructs are tested: quality of care (composed of system-level factors) and quality of dying (comprised of resident/family outcomes). Data obtained from 85 Midwestern nursing homes and 1282 interviews with bereaved family members were used to evaluate both constructs.

RESULTS

Confirmatory factor analyses were conducted and evidence of validity and reliability were obtained for both.

CONCLUSION

For health services researchers, expanded models that include system-level factors as well as more comprehensive and psychometrically sound models of resident outcomes stand to inform efforts to improve care in this very important area.

Goals set in the land of the living/dying: a longitudinal study of patients living with advanced cancer

A longitudinal qualitative research study was undertaken to provide an understanding of a prolonged experience of advanced cancer, as seen through the eyes of dying individuals. Using a variant of the grounded theory method, the authors theoretically sampled, from outpatient clinics in a large comprehensive cancer treatment center, 27 patients with either advanced lung or gastrointestinal cancer who had an expected survival of up to 2 years. The authors conducted a total of 54 interviews with these patients to learn of their experience of advanced cancer. The authors represent their experience with the core category: striving to grow in the land of the living/dying, symbolizing their sense of finding themselves in a borderland between life and death where their efforts focused on 3 common goals. controlling dying, valuing life in the present, and creating a living legacy. They provide a longitudinal account of how these goals were addressed throughout the illness trajectory and discuss the theoretical and clinical implications of this understanding for the experience of dying from advanced cancer.

Posttraumatic stress disorder at the end of life: extant research and proposed psychosocial treatment approach

According to some estimates, 84% of people experience a traumatic event during their lives (Vrana & Lauterbach, 1994), and 15% to 24% then develop posttraumatic stress disorder (PTSD). Many carry with them lasting effects of trauma as they age and enter the last phase of life. PTSD manifests in unique ways at the end of life, possibly disrupting factors associated with a positive dying process, including social support, medical communication, life review, and acceptance of death. Terminally ill people with PTSD may suffer more emotional distress, lower quality of life, and poorer medical prognosis than those without PTSD. Unfortunately, healthcare providers may not be trained to address this issue. This article reviews the literature concerning how PTSD may affect the end of life and proposes an intervention model based on a palliative care philosophy.

Poor Accrual in Palliative Research Studies: An Update From the Rapid Response Radiotherapy Program

Background

In June 2003, the Rapid Response Radiotherapy Program (RRRP) implemented changes to recruitment strategies in attempts to increase patient accrual to research studies. Such modifications included the use of a dedicated research assistant to screen for and identify eligible study patients, the introduction of more appropriate inclusion criteria, and the switch towards telephone interviews to minimize patient burden. The purpose of this study is to provide an update on patient accrual in the RRRP.

Methods

All patients seen in the RRRP from January 2002 to December 2009 were recorded in a prospective database. Reasons for referral, eligibility for clinical trials, reasons for non-accrual, and various demographics information were recorded. Descriptive statistics summarized findings.

Results

A total of 4726 patient visits were recorded from January 1st, 2002 to December 31st, 2009. Prior to changes, the overall rate of accrual into research studies was 14.9% versus 48.1% after changes were implemented. Patients were not accrued onto studies mainly to due ineligibility according to study protocol. Other reasons such as language barrier (12.1%), physician objection (3.5%), patient declining participation (11.3%) and lack of a research assistant (9.3%) were cited.

Conclusions

Changes in clinical structure and study design can significantly impact accrual patterns in palliative radiotherapy studies. Despite these changes however, the majority of patients are still not enrolled in studies. Therefore additional efforts need to be made to maximize patient accrual and minimize attrition.

Quality of life among patients receiving palliative care in South Africa and Uganda: a multi-centred study

BACKGROUND

Quality of life (QOL) is a core outcome of palliative care, yet in African settings there is a lack of evidence on patients' levels of QOL. We aimed to describe QOL among patients with incurable, progressive disease receiving palliative care in South Africa and Uganda, to compare QOL in cancer and HIV, to determine how domains of QOL correlate with overall QOL, and compare levels of QOL in this population with those in other studies using the same tool.

METHODS

A cross-sectional survey was conducted using the Missoula Vitas Quality of Life Index (MVQOLI), a 26-item QOL questionnaire with five subscales (Function, Symptom, Interpersonal, Well being, Transcendent) covering physical, social, psychological and spiritual domains and one global QOL item. One item in each subscale assesses the subjective importance of the domain on a score from 1 (least important) to 5 (most important), used to weight the contribution of the subscale towards the Total QOL score. The tool was translated into 6 languages and administered to consecutively recruited patients at four facilities in South Africa and one in Uganda.

RESULTS

285 patients were recruited, with a mean age of 40.1; 197 (69.1%) were female. Patients' primary diagnoses were HIV (80.7%), cancer (17.9%) and other conditions (1.4%). The mean global QOL score was 2.81 (possible range 0 (worst) to 5 (best)); mean Total score 17.32 (possible range 0 to 30). Patients scored most poorly on Function (mean 0.21), followed by Well being (2.59), Symptoms (5.38), Transcendent (5.50), Interpersonal (9.53) (possible range for subscale scores -30 to 30). Most important to patients were: close relationships (mean 4.13), feeling at peace (4.12), sense of meaning in life (4.10), being active (3.84), physical comfort (2.58). Cancer patients were predominantly recruited at three of the sites; hence comparison with HIV-infected patients was restricted to these sites. HIV+ patients (n = 115) scored significantly worse than cancer patients (n = 50) on Well being (Z = -2.778, p = 0.005), Transcendence (Z = -2.693, p = 0.007) and Total QOL (Z = -2.564, p = 0.01). Global QOL score was most weakly correlated with Total QOL (r = 0.37) and the Transcendent subscale was most highly correlated (r = 0.77) (both p < 0.001). Patients receiving palliative care in South Africa and Uganda exhibited significantly poorer QOL compared to similar populations in the USA.

CONCLUSIONS

Feeling at peace and having a sense of meaning in life were more important to patients than being active or physical comfort, and spiritual wellbeing correlated most highly with overall QOL. It is therefore vital to identify and meet the psychological and spiritual care needs of patients, as well as to assess and treat pain and other symptoms. Our finding that patients scored most poorly on the Function domain warrants further research.

Perceived success in addressing end-of-life care needs of low-income elders and their families: what has family conflict got to do with it?

The purpose of this study was to examine the predictors of perceived success in addressing the end-of-life care needs of low-income older adults and their family members. Perceived success is defined as the clinician's subjective assessment of the extent to which end-of-life care needs of the patient and family have been met by the interdisciplinary team. The results are drawn from a larger longitudinal multimethod case study designed to understand how end-of-life care is provided to a diverse group of frail elders in an innovative, fully "integrated," managed care program. Data were generated from 120 social work surveys detailing care experiences and outcomes particular to 120 elder deaths. Significant predictors of perceived success for addressing patient needs included patient care needs (β=0.17, P≤0.05), race (β=0.19, P≤0.05), patient preferences elicited (β=0.29, P≤0.01) and honored (β=0.20, P≤0.05), and family conflict (β=-0.24, P≤0.01). Significant predictors of perceived success for addressing family needs included family care needs (β=0.30, P≤0.001), team and administrative resources (β=0.19, P≤0.01), patient preferences honored (β=0.16, P≤0.05), quality of relationship with patient (β=0.27, P≤0.001) and family (β=0.23, P≤0.01), and family conflict (β=-0.31, P≤0.001). This study provides preliminary evidence of differential correlates and predictors of perceived success for addressing patient and family needs, highlighting the detrimental influence of family conflict. Future research is needed to better understand the kinds of assessment and intervention protocols that might prevent or ameliorate conflict and enhance structures and process-of-care variables to facilitate more successful outcomes.

Researching the end-of-life in old age: cultural, ethical and methodological issues

Increased life expectancy has strengthened the association between old age and death, with significant implications for gerontology and for the generation of knowledge through research. The global rise in chronic disease has had a significant impact on the duration and shape of dying trajectories in old age and their variations. This development poses ethical and methodological challenges for researchers, not least because it is often difficult to establish whether an older person is ‘dying from’ as opposed to ‘living with’ one or more diseases. This paper reports a comprehensive literature review of empirical research on the end-of-life in old age, and has two inter-related themes. It explores the social and cultural contexts of death and critically analyses the methods and ethical approaches adopted by researchers. Cross-cultural studies and studies in which cultural factors were of prime interest were selected with a view to examining the concept of a ‘good death’ in old age. The paper discusses the evidence of cultural similarities and differences and the impact of social and cultural change on ideas concerning a good death. It identifies contemporary influences and pressures on end-of-life care for older people and discusses the significance of communication and the roles of families and service providers. The paper concludes by identifying substantive and methodological lessons for researchers in gerontology and suggests ways in which the impact of research might be enhanced.

Methodological challenges in conducting a multi-site randomized clinical trial of massage therapy in hospice

Researchers conducting multi-site studies of interventions for end-of-life symptom management face significant challenges with respect to obtaining an adequate sample and training and retaining on-site study teams. The purpose of this paper is to describe the strategies and responses to these challenges in a multi-site randomized clinical trial (RCT) of the efficacy of massage therapy for decreasing pain among patients with advanced cancer in palliative care/hospice settings. Over a period of 36 months, we enrolled 380 participants across 15 sites; 27% of whom withdrew prior to study completion (less than the anticipated 30% rate). We saw an average of 68% turnover amongst study staff. Three key qualities characterized successful on-site study teams: (1) organizational commitment; (2) strong leadership from on-site study coordinators; and (3) effective lines of communication between the on-site study coordinators and both their teams and the university-based research team. Issues of recruitment, retention and training should be accounted for in hospice-based research study design and budgeting.

The development and validation of a novel questionnaire to measure patient and family satisfaction with end-of-life care: the Canadian Health Care Evaluation Project (CANHELP) Questionnaire

The purpose of this study was to further validate a novel instrument to measure satisfaction with end-of-life care, called the Canadian Health Care Evaluation Project (CANHELP) questionnaire. Data were collected by a cross-sectional survey of patients who had advanced, life-limiting illnesses and their family caregivers, and who completed CANHELP, a global rating of satisfaction, and a quality of life questionnaire. We conducted factor analysis, assessed internal consistency using Cronbach's alpha, and evaluated construct validity by describing the correlation amongst CANHELP, global rating of satisfaction and the quality of life questionnaire scores. There were 361 patient and 193 family questionnaires available for analysis. In the factor analysis, we identified six easily interpretable factors which explained 55.4% and 60.2% of the variance for the patient and caregiver questionnaire, respectively. For the patient version, the subscales derived from these factors were Relationship with Doctors, Illness Management, Communication, Decision-Making, Role of the Family, and Your Well-being. For the family questionnaire, the factors were Relationship with Doctors, Characteristics of Doctors and Nurses, Illness Management, Communication and Decision-Making, Your Involvement, and Your Well-being. Each subscale for each questionnaire had acceptable to excellent internal consistency (Cronbach's alpha ranged from 0.69-0.94). We observed good correlations between the CANHELP overall satisfaction score and global rating of satisfaction (correlation coefficient 0.49 and 0.63 for patient and family, respectively) which was greater than the correlations between CANHELP and the quality of life instruments. We conclude that the CANHELP Questionnaire is a valid and internally consistent instrument to measure satisfaction with end-of-life care.
