Interviewing terminally ill people: is it fair to take their time?

Long-distance caregiving at the end of life: a protocol for an exploratory qualitative study in Germany

Background

Of the approximately 4.7 million people in Germany caring for a relative, many live at a geographical distance from their loved one. The provision of remote care to a terminally ill patient is associated with specific challenges and burdens. In the German context, research is lacking on the specific experiences and needs of caregivers in end-of-life situations who are geographically distanced from their relative. Thus, the overarching goal of the proposed study is to detail the specifics of long-distance caregiving at the end of life in Germany, determining the role played by physical distance in shaping end-of-life caregiving and identifying the needs of long-distance caregivers in this situation.

Methods

The exploratory qualitative study will be guided by an inductive logic, drawing on one-time semi-structured interviews. To uncover the multiplicity of caregiving experiences, long-distance caregivers of both patients receiving early palliative care and patients at a very advanced stage of disease will be included. The study will be divided into five phases: (1) preparation and pretest, (2) data collection and primary analysis, (3) data analysis and interpretation, (4) advisory board workshop and (5) conclusions and recommendations.

Discussion

The study will aim at generating valuable insight regarding the experiences and needs of family caregivers of end-of-life patients. This is particularly relevant, given that families are becoming increasingly geographically dispersed. As this trend continues, it will challenge traditional models of family care and shed light on novel caregiving issues that will need to be addressed through social and health policy.

Trial registration

The study was prospectively registered in the German Clinical Trials Register (Deutsches Register Klinischer Studien) (Registration N° DRKS00024164; date of registration: January 25, 2021), and is searchable under the International Clinical Trials Registry Platform Search Portal of the World Health Organization, under the German Clinical Trials Register number.

Methodological Reflections on the Recruitment of Adult Child-Parent Dyads for End-of-Life Research in Germany: Experiences From the Dy@EoL Study

CONTEXT

Although high-quality research with patients and family members is needed to improve palliative care, difficulties in recruitment are often reported.

OBJECTIVES

The present article analyzes the authors' experiences in recruiting participants of two types of dyads for the study "Dy@EoL-Interaction at the end of life in dyads of parents and adult children". Recruitment challenges and factors found to improve recruitment are examined.

METHODS

Between February 2018 and November 2019, the research team cooperated with diverse inpatient and ambulatory palliative and hospice care providers to recruit both dyads. Cooperation strategies and adaptations were protocolled. Data on (non-)participation were recorded and analyzed using descriptive statistics.

RESULTS

The recruitment rate was 34.6% (dyad 1, terminally ill adult children with parents: 36.4%; dyad 2, terminally ill parents with adult children: 33.9%). In total, 82.2% of participants were recruited from inpatient settings. The research team has applied various strategies, such as public outreach activities and the extension of recruitment partners. The study protocol was adapted at an early stage to include single participants. Of all patients, 47.7% participated without their dyad partner. The main reason to exclude their family member was the patients' wish to protect them from extraburden.

CONCLUSION

The recruitment was more successful in inpatient than in ambulatory settings. The extension of recruitment partners was beneficial to recruit participants from ambulatory contexts. The inclusion of single participants was conducive as a great number of patients participated without their dyad partner. Sharing the obtained experiences can be helpful for future research planning.

Using the Canadian Code Of Ethics for Registered Nurses to Explore Ethics in Palliative Care Research

Nursing research in palliative care raises specific and challenging ethical issues. Questions have arisen about whether such research is morally justified, given the low likelihood of direct benefit to dying patients as research participants. The Canadian Code of ethics for registered nurses outlines eight primary values intended to guide nursing practice. We use these values to explore the moral dimensions of research with the palliative care population. Our conclusion is that palliative care research is needed to foster excellent care for these patients and their families, but that nurses must remain constantly vigilant to ensure that participants are protected from resultant harms. Through this exploration we highlight particular considerations that nurse researchers must contemplate when accessing a vulnerable population.

Effectiveness of the "Cancer Home-Life Intervention" on everyday activities and quality of life in people with advanced cancer living at home: a randomised controlled trial and an economic evaluation

Background

During the past decade an increasing number of people live with advanced cancer mainly due to improved medical treatment. Research has shown that many people with advanced cancer have problems with everyday activities, which have negative impact on their quality of life, and that they spend a considerable part of their time at home. Still, research on interventions to support the performance of and participation in everyday activities is only scarcely available. Therefore, the occupational therapy-based “Cancer Home-Life Intervention” consisting of tailored adaptive interventions applied in the participant’s home environment was developed.

The objective of this study is to examine the effectiveness and cost-effectiveness of the Cancer Home-Life Intervention compared to usual care on the performance of and participation in everyday activities and quality of life in people with advanced cancer living at home.

Methods

The study is a randomised, controlled trial (RCT) including an economic evaluation. The required sample size of 272 adults living at home will be recruited from outpatient clinics at two Danish hospitals. They should be diagnosed with cancer; evaluated incurable by the responsible oncologist; and with a functional level 1–2 on the WHO performance scale. The primary outcome is the quality of performance of activities of daily living. Secondary outcomes are problems with prioritised everyday activities; autonomy and participation; and health-related quality of life. Participants are randomly assigned to: a) The Cancer Home-Life Intervention in addition to usual care, and b) Usual care alone.

Discussion

The trial will show whether the Cancer Home-Life Intervention provides better support for people with advanced cancer living at home in performing and participating in everyday activities, and whether it contributes to their health-related quality of life. The economic evaluation alongside the RCT will show if the Cancer Home-Life Intervention is cost-effective. The trial will also show the acceptability of the intervention to the target group, and whether subgroups of participants will benefit more than others.

The effects of cancer research participation on patient experience: a mixed-methods analysis

Patient-reported benefits of research participation have been described by study participants; however, many studies have small sample sizes or are limited to patient groups with poor prognoses. The purpose of this study was to explore the effects of research participation on patient experience using survey responses from a large, national sample of cancer patients (N = 66 462) and interviews with breast cancer patients attending a London trust. Multivariate logistic regression was used to investigate associations between taking part in research and positive patient experience. Based on our analysis, patients who participated in research were more likely to rate their overall care and treatment as 'very good/excellent' (OR_adj :1.64, 95%CI: 1.53-1.76, P < 0.001) and to describe positive patient experiences, such as better access to non-standard care, better interactions with staff and being treated as an individual. However, findings from our interviews indicated that there was no common understanding of what constitutes cancer research and no clear delineation between research participation and standard care, from the patient perspective. Further work to explore how participation positively influences patient experience would be useful to develop strategies to improve care and treatment for all patients regardless of whether or not they choose, or have the opportunity, to take part in research.

Researching sensitive and emotive topics: The participants’ voice

There are different groups in society who may be considered vulnerable, for example those experiencing mental or physical health issues, learning disabilities, prisoners or children. There are, however, other groups in society who may also be regarded as vulnerable, such as those who are bereaved. Vulnerability in relation to the bereaved occurs as a result of experiencing a normal life event, death or a loss. In this situation vulnerability may be transient and, depending upon the management of the bereavement, generally temporary. Unlike the aforementioned groups, participants required for this type of research (bereavement, death and dying) are able to consent themselves into projects, and the capacity to do so is not an issue. Undertaking research with those who may be considered vulnerable into sensitive, emotive topics such as death and dying can create difficulties for the National Research Ethics Service (NRES), making it difficult to get approval for such studies. It appears that the ethical issues are concerned with not wishing to cause distress to participants when asked for research purposes to recollect what for some may have been emotionally challenging and traumatic events. The article offers a narrative, reflective account of the above from several perspectives: being employed as a contract researcher in a university; having experience of being an active member of a National Health Service Research Ethics Committee; and later assuming the role of full-time postgraduate (PhD) student requiring ethical approval to undertake research with what may be considered a vulnerable group involving a sensitive and emotive topic. Valuable insights from participants – their views on participation in an emotive research project and good practice in research having been explored via questionnaire – are highlighted and discussed.

Patient, caregiver, health professional and researcher views and experiences of participating in research at the end of life: a critical interpretive synthesis of the literature

Background

The development of the evidence-base informing end of life (EoL) care is hampered by the assumption that patients at the EoL are too vulnerable to participate in research. This study aims to systematically and critically review the evidence regarding the experiences and views of patients, caregivers, professionals and researchers about participation in EoL care research, and to identify best practices in research participation.

Methods

We searched seven electronic databases, and hand searched three journals and the bibliographies of relevant papers. Inclusion criteria were original research papers on involvement in EoL care research or its impact on participants. Critical interpretive synthesis was used to integrate the whole body of empirical evidence on this topic and generate theoretical categories from the evidence.

Results

Of a total of 239 identified studies, 20 studies met the inclusion criteria, from: the US (11), the UK (6) and Australia (3). Most focused on patients with cancer (12) and were conducted in hospices (9) or hospitals (7). Studies enquired about issues related to: EoL care research in general (5), specific research methods (13), and trial research (2). The studies evaluating willingness to participate in EoL care research showed positive outcomes across the different parties involved in research. Factors influencing willingness were mainly physical and cognitive impairment. Participating in research was a positive experience for most patients and carers but a minority experienced distress. This was related to: characteristics of the participants; the type of research; or the way it was conducted. Participatory study designs were found particularly suitable for enabling the inclusion of a wide range of participants.

Conclusion

The evidence explored within this study demonstrates that the ethical concerns regarding patient participation in EoL care research are often unjustified. However, research studies in EoL care require careful design and execution that incorporates sensitivity to participants’ needs and concerns to enable their participation. An innovative conceptual model for research participation relevant for potentially vulnerable people was developed.

Methodological challenges in researching psychological distress and psychiatric morbidity among patients with advanced cancer: what does the literature (not) tell us?

Patients with advanced cancer experience multiple demands and losses that place them at risk for experiencing psychological distress. Researchers can face challenges in conducting research among this population because of their poor levels of physical and cognitive functioning. This paper aims to develop our understanding of these challenges. A systematic literature review was conducted of papers describing surveys in which a stated aim was to measure rates of psychological distress or psychiatric morbidity among patients with advanced cancer. We also included papers that focused on the development of assessment tools. Studies were identified through computerized (MEDLINE and PsycINFO) and manual searches for the years 1995-2009. Twenty-eight papers met the inclusion criteria. They describe findings in relation to a total of 3942 patients. The sample sizes ranged from 25 to 422 (median = 87). The main methodological challenge identified is the recruitment of large and representative samples. Significant portions of the advanced cancer population are excluded from distress studies or are refusing to take part. In conclusion, researchers can enhance the methodological knowledge base by presenting more detailed accounts of the participant recruitment and data collection processes. Future researchers should strive to develop more flexible methods of assessing distress among patients with advanced disease.

Ethical openings in palliative home care practice

Understanding how a nurse acts in a particular situation reveals how nurses enact their ethics in day-to-day nursing. Our ethical frameworks assist us when we experience serious ethical dilemmas. Yet how a nurse responds in situations of daily practice is contingent upon all the presenting cues that build the current moment. In this article, we look at how a home care nurse responds to the ethical opening that arises when the nurse enters a person’s home. We discuss how the home presents the nurse with knowledge that informs the provision of ethical nursing care. The analysis is based on findings from an interpretive research study in palliative home care in Canada. Through interpretive analysis of a nursing situation we delineate how the nurse engages with the whole and acts inside the moment. The analysis shows how home care nurses are ethically determined to engage with whatever is going on in a patient’s home.

Revisiting biographical disruption: exploring individual embodied illness experience in people with terminal cancer

Biographical accounts of illness offer useful insights into the social and adaptive processes of living with chronic illness. Yet there are concerns that the underlying theoretical assumptions of a reflexive self seeking to maintain meaning may not reflect the lived experience of individuals. A narrative emphasis may neglect the importance of emotional/felt experiences; while an analytical focus on disruptive processes may not adequately reflect the totality of actual events. In this study, we explored how well biographical theory supports understanding of individual lived experience. Narratives from 19 individuals identified from General Practice lists with a terminal diagnosis of cancer were analysed using the holistic-form approach described by Lieblich. Participants described an ongoing process of living their life, 'managing' disruptive events and maintaining an overall sense of well-being (narrative form = biographical flow). For a minority, continuity was lost when people's capacity to continue living their everyday lives was overwhelmed (narrative form = fracture). The identified emphasis was on individual creative capacity in the face of terminal illness, highlighting the importance of embodied experience in understanding outcome and need. Maintaining continuity was draining: exhaustion precipitated fracture and thus need for external help to restore continuity. By focusing on feelings associated with overall narrative form, rather than individual disruptive events, we highlight the context in which disruptive events are experienced, and individual perceptions of their relative importance. We conclude that combining narrative and emotion offers new insights into the value of understanding of biographical accounts of illness in the context of individual creative capacity. We discuss the possibilities for new approaches to clinical assessment and management of need.

Review: what evidence is there about the specific environmental needs of older people who are near the end of life and are cared for in hospices or similar institutions? A literature review

Relatively little is known about the type of physical environment which is needed and preferred by patients aged 65 and over, with a prognosis of 1 year or less, who are receiving care in hospitals, care homes and hospices, and their families and staff. A narrative literature review was conducted to identify and analyse evidence on this issue, with twenty-nine papers meeting the inclusion criteria. The patients were found to have a wide range of views on their environment, but there was some variation between the views of patients and those of their families and staff. Four main themes emerged: the physical environment should be 'homely'; it should support patients' need for social interaction and privacy; it should support the caring activities of staff, family members and patients; and it should allow opportunities for spiritual expression. It is evident that the physical environment contributes significantly to the quality of life of older people with a life-limiting illness, and there is a need for more research in this area. Regular assessment of patients' environmental needs should form part of care planning.

Review: a narrative review of the published ethical debates in palliative care research and an assessment of their adequacy to inform research governance

The quality of research, and the resulting quality of evidence available to guide palliative care, is dependent on the ethical decisions underpinning its design, conduct and report. Whilst much has been published debating the ethics of palliative care research, an assessment of the quality and synthesis of the central debates is not available. Such a review is timely to inform research governance. The methodology of this study is based on the principles of systematic reviews. Fifty-seven papers were reviewed following a thorough search, and were critically appraised for their literary quality, the knowledge on which they drew and the research standards they addressed. The debates identified address vulnerability, moral appropriateness, consent, gate-keeping and inclusion and research culture. The quality of debate and the sources of knowledge varied. The debate was rich in quality and knowledge with respect to the protection of the dignity, rights and safety of research participants, but less developed in relation to those of researchers and other staff. There is also little debate about the ethics of reporting of research and the ethics underpinning research leadership. A framework is offered that reconciles the ethical issues raised with potential methodological strategies identified from the review.

Unbearability of suffering at the end of life: the development of a new measuring device, the SOS-V

Background

Unbearable suffering is an important issue in end-of-life decisions. However, there has been no systematic, prospective, patient-oriented research which has focused on unbearable suffering, nor is there a suitable measurement instrument. This article describes the methodological development of a quantitative instrument to measure the nature and intensity of unbearable suffering, practical aspects of its use in end-stage cancer patients in general practice, and studies content validity and psychometric properties.

Methods

Recognizing the conceptual difference between unbearability of suffering and extent or intensity of suffering, we developed an instrument. The compilation of aspects considered to be of importance was based on a literature search. Psychometric properties were determined on results of the first interviews with 64 end-stage cancer patients that participated in a longitudinal study in the Netherlands.

Results

The instrument measures five domains: medical signs and symptoms, loss of function, personal aspects, aspects of environment, and nature and prognosis of the disease. Sixty nine aspects were investigated, and an overall score was asked. In 64 end-stage cancer patients the instrument was used in total 153 times with an average interview time varying from 20-40 minutes. Cronbachs alpha's of the subscales were in majority above 0.7. The sum scores of (sub)scales were correlated strongly to overall measures on suffering.

Conclusion

The SOS-V is an instrument for measuring the unbearability of suffering in end-stage cancer patients with good content validity and psychometric properties, which is feasible to be used in practice. This structured instrument makes it possible to identify and study unbearable suffering in a quantitative and patient-oriented way.

“I Come Because I Can”: Stories of Hope from the Cancer Drop in

Hospices are now the established institutionalized home of specialist palliative care practice in the United Kingdom. Despite attempts to widen access, the dominant patient group continues to be cancer sufferers. A multidisciplinary approach to the support of patients characterizes this field of health care, with both skilled professionals and volunteers attending to patients' physical, emotional, and spiritual needs. Day care, as one type of provision within hospice services, has its own practice territory with wide variations now well documented in the literature. This article reports on a participant observation study that explored the day care provision of a community hospice trust located in southern England. Drawing on the concepts of palliative care and hope in the lives of terminally ill people, findings suggest that this facility helps to counter the isolating effects of cancer and that self-comparison acts as motivation to attend day care, contributing to hope for continued survival.

The meaning of quality of life: narrations by patients with incurable cancer in palliative home care

OBJECTIVE

The objective of this qualitative study was to elucidate the meaning of quality of life as narrated by patients with incurable cancer approaching death in palliative home care in Sweden.

METHODS

To gain a deeper understanding of what quality of life means for dying patients, data were collected from narrative interviews with eight patients in their homes in 2004-2006. Qualitative content analysis was used to interpret the meaning regarding quality of life.

RESULTS

Three main themes were found: being in intense suffering, having breathing space in suffering, and being at home. Living with incurable cancer at the end of life was experienced as living in physical distress as the body became incapacitated by unexpected physical complications. This incapacity had consequences on patients' psychological, social, and existential well-being. As the complication phase abated, the patients experienced that they regained hopefulness and had time to reflect on existential issues. Patients were provided affirmative care at home from family caregivers and the palliative home care team.

SIGNIFICANCE OF RESULTS

This study shows that it is feasible to perform individual interviews with patients approaching death and elucidate the meaning of patients' quality of life in palliative home care. Patients oscillate between being in intense suffering and having breathing space in this suffering, which somewhat opposes the traditional picture of a continuous linear deterioration. Being cared for at home by family caregivers and health care professionals provided a sense of independency and security. Being at home safeguards patients' entire life situation and increases quality of life.

Improving the effectiveness of interventions in palliative care: the potential role of qualitative research in enhancing evidence from randomized controlled trials

Evaluating interventions in palliative care using randomized controlled trials (RCTs) has helped advance the specialty and create an evidence base for the delivery of care. RCTs, however, are notoriously difficult to conduct in palliative care, raising a variety of practical, ethical and moral dilemmas. Mixed-methods research, which combines qualitative research and RCTs, offers a potential solution to these problems. This paper begins by examining the theoretical basis for combining the two approaches, before reviewing the specific role qualitative research could play in planning, conducting and implementing trials. The paper then goes on to explore how palliative care research currently uses the mixed-methods approach, by searching the trials included in six Cochrane Systematic Reviews (n = 146) on the incorporation of qualitative research. Only one trial undertook qualitative research. These findings reflect some of the challenges facing mixed-methods research, which include lack of experience in a research team, the problems of obtaining funding and difficulties in publishing. The paper concludes that while combining qualitative and quantitative research is not a panacea for methodological problems in palliative care research, with careful planning and integration, the approach may enhance the clinical and ethical utility of trial findings, which in turn will improve patient care.

Case study research methods in end-of-life care: reflections on three studies

AIM

This paper is an evaluation of the use of case study methods, drawing on three research studies conducted by the authors in end-of-life care and bereavement.

BACKGROUND

Case study methods have their origins in social anthropology and draw on the principles of naturalistic inquiry. They have been used in a number of disciplines, including qualitative sociology, management science, education and organizational psychology for the understanding and evaluation of complex social systems. They are an appropriate research design for examining processes and outcomes in dynamic healthcare organizations, where it is important to obtain multiple perspectives.

METHOD

We explore issues in case study research design, recruitment and data collection drawing on three studies conducted between 2000 and 2005 in six community hospitals, five adult hospice bereavement services and eight childhood bereavement services in the United Kingdom. Quantitative and qualitative data were collected using interviews, focus groups, observations, documentary analysis, standardized measures and questionnaires.

DISCUSSION

The process of case study design is described, including building upon a clear rationale for the selection of cases, collection of data, preparation of single case reports, cross-case analysis and interpretation. In a critical discussion of recruitment, we recommend identification of a key contact person at each site to facilitate access and minimize misunderstanding, disruption to clinical services and 'gate-keeping'. Three principal methods of data collection: interviews, observation and documentary data analysis form the foundation of the rich data set necessary to explore cases in their situational contexts.

CONCLUSION

Case study methods may be empowering for participants because they value their experiences and reveal how their work contributes to teamwork within organizations. They can therefore be both affirming and challenging, as they may expose both conflicts and tensions.

Hospitalized patients experienced suffering in life with incurable cancer

The concept 'suffering' has been central within nursing since Florence Nightingale. But few researchers have made empirical studies about the lived phenomenon. Several researchers within nursing agree that more research concerning individual groups of patients has to be initiated. Within research about patients with incurable cancer focus has been on death, the terminal period and patients experience of being dying. This qualitative study was initiated to describe the characteristics of a group of Danish hospitalized patients' experienced suffering in life with incurable cancer. Twenty-five semi-structured interviews were arranged with 12 patients ones a week within a period of 4 weeks. In week 2 and 4, the interviews were supplemented by questions developed on the basis of the potential signs of suffering which appeared during the participant observations that took place the day before each interview. C. S. Peirce's semiotic and phenomenological grounded theory of signs was used in order to identify the potential signs. A phenomenological methodology developed by A. Giorgi was used to develop and describe the general structure of the phenomenon. The phenomenon is described as: 'The experience of living in an increasingly unpredictable existents at the mercy of the body, the consciousness, the illness, the death, the treatment, the professionals, one's articulateness, the past, the present and the future, influenced by increasing powerlessness, loneliness and isolation, and the experience of existing in an persistent, and with time, unconquerable struggle to maintain and regain control'.

The experience of research participation for family caregivers of palliative care cancer patients

There have been concerns raised regarding the ethical merit of involving dying patients and family caregivers as research participants. This study sought feedback from 103 primary family caregivers who had participated in a longitudinal research project. Caregivers were sent a questionnaire regarding the benefits and negative aspects associated with participating in research while also supporting or having supported a relative dying of cancer. The study identified that almost three quarters (71.1%) of the 45 respondents reported benefits of being involved in research and the majority (88.9%) cited no negative aspects associated with research participation. Findings of the study suggest that it is pertinent to invite family caregivers to be involved in palliative care research. Moreover, this study demonstrated that not only is it probably safe for family caregivers to be involved in research but also that many participants actually derive benefits.

The communication of palliative care for the elderly cancer patient

Palliative care (PC) is often recommended by physicians for their elderly patients who are terminally ill. In contrast to hospice care, which precludes the use of any curative treatment at life's end stages, PC seeks primarily to comfort patients and to keep them pain free, yet it does not necessarily preclude medical treatment. It does seek to attend to patients' physical as well as psychological, emotional, spiritual, and existential needs in an attempt to enhance overall quality of life. A review of current literature in PC for oncology patients, elderly and otherwise, reveals a curious irony: Although PC plausibly entails a holistic, patient-centered approach to health care, much of the research on PC and, apparently, many of the practices in PC focus almost exclusively on the biomedical approach to patient care, particularly in regard to pain and symptom management. Furthermore, few methods in PC research incorporate patients' narratives and lived experiences in the final stages of their lives. We argue that a holistic, patient-centered approach must guide research in PC, including the treatment of elderly patients as "active interpreters, managers, and creators of the meaning of their health and illness" (Vanderford, Jenks, & Sharf, 1997, p.14) and of the meaning of their lives.

Methodologic issues in collecting data from debilitated patients with cancer near the end of life

PURPOSE/OBJECTIVES

To report the experience of a group of researchers who have had a year of experience in a clinical trial with homecare hospice patients.

SAMPLE

150 hospice patients with cancer and their primary caregivers who were accrued to a National Cancer Institute-funded clinical trial focusing on quality of life.

METHODS

The investigative team kept careful records of the numbers of patient/caregiver dyads accrued to the study and the reasons for nonaccrual as well as reasons for attrition. Data were analyzed using descriptive statistics.

FINDINGS

During a nine-month period, the hospice admitted 2,517 patients; 75% had cancer and 95% had caregivers, making them eligible for the study. However, after further screening, only 19% were eligible for contact and only 5% finally were accrued to the study. For the 125 patient/caregiver dyads actually accrued to the study, baseline data were obtained on only 50% and evaluable follow-up data on only 50%.

CONCLUSIONS

Accruing patients to clinical trials and retaining them when they are critically ill and near death are extraordinarily difficult tasks. The inability to recruit and retain subjects for clinical trials has implications for integrity of data, data analysis, success of the project, and the cost of conducting such projects in the future.
