Thinking outside the box: depression, hope, and meaning at the end of life

The role of patients' stories in medicine: a systematic scoping review

BACKGROUND

Patients' stories provide Palliative Care physicians with a glimpse into the former's lives and their psycho-emotional, sociocultural, and contextual considerations. Yet, few physicians are trained to interpret and apply patients' stories in their practice. Inherent variability in how stories are transmitted and interpreted raises questions over their potential effects on care. Amidst a dearth of accounts in Palliative Care, we map current use of patient stories to guide the training, assessment, and oversight of this 'care influencing' practice in medicine.

METHODS

This systematic scoping review was guided by the Systematic Evidence-Based Approach (SEBA) to ensure a reproducible and structured approach. The themes and categories identified through the Split Approach's concurrent and independent thematic and directed content analyses provided a comprehensive sketch of the included articles. The Jigsaw Perspective combined the themes and categories identified. The last stage of SEBA compared these results with two recent reviews of storytelling to ensure consistency of the domains created that guided the discussion.

RESULTS

Ten thousand two hundred seven articles were reviewed, 963 full text articles were evaluated, and 199 articles were included. The four domains identified were study characteristics, benefits, approaches, and positive effects and concerns.

CONCLUSION

Stories support patient-centered, personalized, and holistic clinical care. However, variability in the stories, their interpretations and use in care decisions underscore the need for further study on the structuring, teaching, assessing, and delivery of this 'care influencing' practice.

Herth Hope Index: A Psychometric Evaluation Study within a Sample of Greek Patients with Cancer

Objectives:

This study aims to develop the Greek version of the Herth Hope Index (HHI) and assess its psychometric properties to a palliative care patient sample, using a cross-sectional design.

Materials and Methods:

The HHI was translated into Greek (HHI-Gr) using the ‘forward-backward’ procedure. It was administered to 130 eligible cancer patients, while for the stability of patients’ responses, 40 of these patients completed the HHI-Gr 3 days later. Along with the HHI-Gr, patients also completed the Hospital Anxiety and Depression Scale (HADS) and the Beck Hopelessness Scale (BHS). The HHI-Gr internal consistency reliability (Cronbach’s a), stability (intraclass correlation coefficient [ICC]), factor structure (factor analysis) and convergent validity (correlation with the HADS and the BHS questionnaires) were examined using the Eastern Cooperative Oncology Group (ECOG) performance status.

Results:

The HHI-Gr yielded a one-factor model and a Cronbach alpha (0.860) with excellent internal consistency reliability and stability ICC (>0.90). Satisfactory convergent validity was supported by the correlation analysis between the HHI-Gr and BHS (r = 0.718, P < 0.001). Overall test-retest reliability was satisfactory with a range between 0.77 and 0.96 (P < 0.001).

Conclusion:

These results demonstrate that the HHI-Gr is an instrument with satisfactory psychometric properties and is a valid research tool for the measurement of the levels of hope among Greek oncology patients.

Narrative Interventions in the Palliative Care Setting: A Scoping Review

CONTEXT

This scoping review maps the existing literature on narrative interventions within a palliative care and end-of-life context.

OBJECTIVES

A scoping review was performed to address the following research question: What observational or randomized controlled trials have been performed to evaluate narrative interventions in the palliative care setting?

METHODS

A search across multiple electronic databases was performed. The search results were screened. Relevant articles were reviewed for the identification of common themes and challenges.

RESULTS

After reviewing 495 citations from electronic searches, and 44 articles from author archives or from manual review of article reference lists, we identified 34 articles for inclusion. Narrative interventions have focused on reflection or communication, and have been studied among providers, students, patients, and caregivers. Only patient/caregiver studies used randomized controlled design. Most studies were small and at the level of evaluating feasibility. Challenges include a high degree of heterogeneity among interventions and heterogeneity among parameters for evaluating those interventions.

CONCLUSION

Narrative interventions are actively being evaluated with the intention of improving communication and well-being among all parties within the palliative care and end-of-life experience. The field would benefit from selecting a subset of outcomes that are comparable across studies, and a common framework for describing narrative interventions. Scant literature exists regarding narrative interventions to assist providers in communication.

Are Repeated Self-Reports of Psychological Variables Feasible for Patients Near the End of Life at a Palliative Care Unit?

BACKGROUND

Patient-reported outcome (PRO) measurement is crucial to assess the benefit of psychotherapeutic interventions. Is repeated assessment of psychometric self-report data possible, as inpatient palliative care patients suffer from physical and psychological symptoms? What is the self-perceived strain caused by the assessment? Objective The main objective of this study was to investigate the feasibility of a repeated comprehensive psychometric self-assessment of inpatient palliative care patients. Secondary objectives were the PROs of the psychometric assessment.

DESIGN

We conducted a prospective cohort study. Patients admitted to our palliative care unit (PCU) were reviewed for eligibility within 72 hours. They were asked for weekly self-reports regarding hope (HHI-D), well-being (FACIT-Sp), anxiety and depression (STADI), and quality of life (QoL; EORTC-QLQ-C-30 single item). The strain caused by the assessment was assessed by a numeric rating scale (0-10) and free comments.

RESULTS

Within 11 months, 219 patients were admitted to the PCU. In total, 92 patients were eligible. The most frequent exclusion criterion was "life expectancy <1 week." A total of 60 patients participated at the first point of measurement. The mean of self-perceived strain (Likert scale 0-10) due to the assessment was 1.44 (SD 1.99) at T1. Twenty-four patients participated twice. Here we found increased scores for physical well-being and QoL.

CONCLUSION

Repeated assessment of psychological conditions is feasible for 27.4% of inpatients at a German PCU. The most limiting factor is life expectancy of only days at admission to the PCU. However, the self-perceived strain is low.

Suffering in Advanced Cancer: A Randomized Control Trial of a Narrative Intervention

BACKGROUND

Advanced cancer can erode patients' wellbeing. Narrative interventions have improved patients' wellbeing, but might not be feasible for widespread implementation.

OBJECTIVES

(1) Test the effects of miLivingStory, a telephone-based life review and illness narrative intervention with online resources and social networking, on community-dwelling advanced cancer patients' wellbeing. (2) Explore intervention use and satisfaction.

PATIENTS AND SETTING

Stage III or IV cancer patients having completed initial therapy were randomized to miLivingStory or to an active control group, miOwnResources. Data and Analysis: Primary outcomes measured at baseline, two and four months included subscales for the FACIT-Sp peace and meaning and the POMS-SF depressed, anxious, and angry mood, scored on 0-4-point Likert scales. Linear mixed modeling, controlling for baseline primary outcome scores, tested for group comparisons of repeated outcome measures. Pairwise comparisons tested for within- and between-group differences. Intervention use and satisfaction data were collected automatically and by survey.

RESULTS

Eighty-six primarily white, female patients with high baseline wellbeing completed the study. There were no between-group differences at baseline or at two months. At four months, miLivingStory had a direct and positive effect for peace (2.86 vs. 2.57, p = 0.029), a trend effect for lower depressed mood (0.55 vs. 0.77, p = 0.097), and appeared to protect against the control group's declining wellbeing between two and four months. miLivingStory use was low and assessed as helpful to quite helpful.

CONCLUSIONS

Telephone-based narrative interventions hold promise in improving advanced cancer patients' wellbeing. Further testing of delivery and implementation strategies is warranted.

Searching for wisdom in oncology care: A scoping review

OBJECTIVE

The concept of "wisdom" is beginning to emerge in the oncology literature, raising questions concerning: (1) how the concept of wisdom is used in oncology literature; (2) the ways in which wisdom has been a focus of inquiry within oncology care; and (3) how wisdom is characterized when the term is used.

METHOD

A scoping review, using Arksey and O'Malley's five-step framework, was undertaken to address these questions. In consultation with oncology reference librarians, "wisdom"- and "oncology"-related search terms were identified, and four electronic databases were searched: CINAHL, SocINDEX, PubMed, and PsychINFO. After removal of duplicates and application of inclusion and exclusion criteria, 58 records were identified and included for analysis.

RESULTS

The concept of wisdom was employed with a breadth of meanings, and 58 records were schematized into 7 genres, including: (1) empirical research with wisdom foregrounded as a study focus (n = 2); (2) empirical research articles where "wisdom" appears in the findings (n = 16); (3) a quality-improvement project where wisdom is an embedded concept (n = 1); (4) essays where wisdom is an aspect of the discussion (n = 5); (5) commentary/opinion pieces where wisdom is an aspect of its focus (n = 6); (6) personal stories describing wisdom as something gleaned from lived experience with cancer (n = 2); and (7) everyday/taken-for-granted uses of wisdom (n = 26).

SIGNIFICANCE OF RESULTS

The notion of wisdom has a taken-for-granted presence in the published oncology literature and holds promise for future research into patient and clinician wisdom in oncology care. Nonetheless, the terminology is varied and unclear. A scholarly focus on wisdom has not been brought to bear in cancer care to the degree it has in other fields, and research is in the early stages. Various characterizations of wisdom are present. If such a resource as "wisdom" exists, dwelling in human experiences and practices, there may be benefit in recognizing wisdom as informing the epistemologies of practice in oncology care.

Resilience and hope during advanced disease: a pilot study with metastatic colorectal cancer patients

Background

The balance between hope-hopelessness plays an important role in the way terminally ill patients report quality of life, and personal resilience may be related to hope at the end of life. The objective of this study was to explore associations between personal resilience, hope, and other possible predictors of hope in advanced cancer patients.

Methods

A cross-sectional pilot study was carried out with metastatic colorectal cancer patients in a tertiary hospital. The patients answered the Connor-Davidson Resilience Scale, Herth Hope Index, Barthel Index, an instrument addressing family and social support, visual-numeric scales for pain and suffering, a two-item screening for depression, socio-demographic and socio-economic information about the family.

Results

Forty-four patients were interviewed (mean age 56 years; range 29-86). A strong correlation was noted between resilience and hope (0.63; p < 0.05). No correlation was found between hope and independence for activities of daily living, support from family and community, and pain and suffering levels. Of the 44 patients, 20 presented with depressive symptoms. These depressive patients had lower resilience (p = 0.005) and hope (p = 0.003), and higher scores of suffering (p < 0.001). The association between resilience and hope kept stable after adjusting for age, gender, and presence of depression (p < 0.001).

Conclusion

Given that resilience is a dynamic, changeable path that can improve hope, resilience-fostering interventions should be most valued in palliative care settings and should be commenced as soon as possible with cancer patients. Patients with advanced stages of non-malignant conditions would also probably benefit from such interventions.

Depressive Symptoms Are Associated with More Hopelessness among White than Black Older Adults

BACKGROUND

Hopelessness is a core component of depression. Our information is, however, very limited on ethnic variations in the magnitude of the link between depression and hopelessness. Using a national sample of older adults in United States, we compared Blacks and Whites for the magnitude of the association between depressive symptoms and hopelessness.

METHODS

With a cross-sectional design, we used baseline data of the Religion, Aging, and Health Survey, 2001. Linear regression models were used for data analysis. Depressive symptoms (CES-D) and hopelessness were conceptualized as independent and dependent variables in different models, respectively. Demographic factors (age and gender), socioeconomic status (education and marital status), and health (self-rated health) were covariates. Ethnicity was the moderator.

RESULTS

In the pooled sample, higher depressive symptoms were predictive of hopelessness, above and beyond all covariates. We also found significant interactions suggesting that the association between depressive symptoms and hopelessness is weaker among Blacks compared to Whites. In ethnic-specific models, there were significant associations between depressive symptoms and hopelessness among Whites but not Blacks.

CONCLUSION

Depressive symptoms accompany more hopelessness among Whites than Blacks. This finding may explain why Blacks with depression have a lower tendency to commit suicide. Future research should test whether or not Whites with depression better respond to psychotherapies and cognitive behavioral therapies that focus on hope enhancement. This finding may explain differential correlates of depression based on race and ethnicity.

Conceptual analysis of suffering in cancer: a systematic review

OBJECTIVE

Patient suffering is a neglected area of care, partly because of poor definitions. The aim of this study was to distill what is currently known about suffering in the health literature in order to generate a conceptual basis for further research.

METHODS

A systematic review focusing on suffering across all cancers was undertaken. The search included peer-reviewed English articles published between 1992 and 2012 in MEDLINE, Embase, PsycINFO and the Cochrane Library databases focusing on conceptualisation of suffering in adult cancer patients. Seminal theoretical articles conceptualising suffering more generally were also eligible. To ensure identification of a sufficiently broad range of conceptualisations of suffering in cancer, the search strategy was drafted iteratively. Study findings were subjected to conceptual analysis using the evolutionary method.

RESULTS

One hundred twenty-eight studies were identified, which discussed definitions or conceptualisations of suffering. In terms of its attributes, suffering is defined as 'an all-encompassing, dynamic, individual phenomenon characterized by the experience of alienation, helplessness, hopelessness and meaninglessness in the sufferer which is difficult for them to articulate. It is multi-dimensional and usually incorporates an undesirable, negative quality.' Surrogate terms, antecedents and consequences of suffering are described.

CONCLUSIONS

The systematic review revealed that suffering includes holistic suffering, which is multidimensional, oscillating, individual and difficult for individuals to express. Opportunities should be provided for patients to express their suffering. The potential for suffering to be transcended needs to be recognized and facilitated by healthcare staff.

Unbearable suffering and requests for euthanasia prospectively studied in end-of-life cancer patients in primary care

Background

An international discussion about whether or not to legally permit euthanasia and (or) physician assisted suicide (EAS) is ongoing. Unbearable suffering in patients may result in a request for EAS. In the Netherlands EAS is legally permitted, and unbearable suffering is one of the central compulsory criteria. The majority of EAS is performed in cancer patients in the primary care practice. In around one in every seven end-of-life cancer patients dying in the primary care setting EAS is performed. The prevalence of unbearable symptoms and overall unbearable suffering in relationship to explicit requests for EAS was studied in a cohort of end-of-life cancer patients in primary care.

Methods

A prospective study in primary care cancer patients estimated to die within six months was performed. Every two months suffering was assessed with the State-of-Suffering V (SOS-V). The SOS-V is a comprehensive instrument for quantitative and qualitative assessment of unbearable suffering related to 69 physical, psychological and social symptoms in five domains.

Results

Out of 148 patients who were asked to participate 76 (51%) entered the study. The studied population were 64 patients who were followed up until death; 27% explicitly requested EAS, which was performed in 8% of the patients. The final interview per patient was analyzed; in four patients the SOS-V was missing. Unbearable symptoms were present in 94% of patients with an explicit request for EAS and in 87% of patients without an explicit request. No differences were found in the prevalence of unbearable suffering for physical, psychological, social and existential symptoms, nor for overall unbearable suffering, between patients who did or who did not explicitly request EAS.

Conclusions

In a population of end-of-life cancer patients cared for in primary care no differences in unbearable suffering were found between patients with and without explicit requests for EAS. The study raises the question whether unbearable suffering is the dominant motive to request for EAS. Most patients suffered from unbearable symptoms, indicating that the compulsory criterion of unbearable suffering may be met a priori in most end-of-life cancer patients dying at home, whether they request EAS or not.

Measuring hope among families impacted by cognitive impairment

The current exploratory investigation aims to establish the reliability and validity of a hope measure, the Herth Hope Index, among families impacted by early cognitive impairment (N = 96). Exploratory factor analysis was used to examine the dimensionality of the measure. Bivariate analyses were used to examine construct validity. The sample had moderately high hope scores. A two-factor structure emerged from the factor analysis, explaining 51.44% of the variance. Both factors exhibited strong internal consistency (Cronbach's alphas ranged from .83 to .86). Satisfaction with social support was positively associated with hope, supporting convergent validity. Neurocognitive status, illness insight, and depression were not associated with hope, indicating discriminant validity. Families impacted by cognitive impairment may maintain hope in the face of a potentially progressive illness, regardless of cognitive status. The Herth Hope Index can be utilized as a reliable and valid measure of hope by practitioners providing support to families impacted by cognitive impairment.

The EORTC emotional functioning computerized adaptive test: phases I-III of a cross-cultural item bank development

Background

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is currently developing computerized adaptive testing measures for the Quality of Life Questionnaire Core-30 (QLQ-C30) scales. The work presented here describes the development of an EORTC item bank for emotional functioning (EF), which is one of the core domains of the QLQ-C30.

Methods

According to the EORTC guidelines on module development, the development of the EF item bank comprised four phases, of which the phases I–III are reported in the present paper.

Phase I involved defining the theoretical framework for the EF item bank and a literature search. Phase II included pre-defined item selection steps and a multi-stage expert review process. In phase III, feedback from cancer patients from different countries was obtained.

Results

On the basis of literature search in phase I, a list of 1750 items was generated. These were reviewed and further developed in phase II with a focus on relevance, redundancy, clarity, and difficulty. The development and selection steps led to a preliminary list of 41 items. In phase III, patient interviews (N = 41; Austria, Denmark, Italy, and the UK) were conducted with the preliminary item list, resulting in some minor changes to item wording. The final list comprised 38 items.

Discussion

The phases I–III of the developmental process have resulted in an EF item list that was well accepted by patients in several countries. The items will be subjected to larger-scale field testing in order to establish their psychometric characteristics and their fit to an item response theory model.

Negotiating hope with chronic obstructive pulmonary disease patients: a qualitative study of patients and healthcare professionals

BACKGROUND

The information needs of patients with chronic obstructive pulmonary disease (COPD) towards the end of life are poorly understood.

AIM

This study explored the views of patients with COPD and healthcare professionals, focusing upon information needs and treatment preferences.

METHOD

In-depth, semi-structured interviews were held with patients with COPD following admission to hospital with respiratory failure, and focus groups held with healthcare professionals from hospital and community settings.

RESULTS

Ten patients were interviewed, who had a median 4 previous hospital admissions, and had smoked for median 47 years. Five focus groups were held with 31 healthcare professionals (18 nurses, 7 doctors, 6 allied health). The theme underpinning all discussions was of tension between maintaining hope and negotiating the reality of the illness and its consequences. Within this theme, patients tended to be optimistic, viewed acute exacerbations as separate from their underlying chronic illness, and were keen for intensive treatments, including intubation if acutely unwell. They had little understanding of the complexities of decision-making around treatment escalation. Both patients and health workers believed that information around end of life should be offered routinely, but delivered in a manner that recognises and maintains a form of hope.

CONCLUSION

Patients and healthcare professionals believe information around illness course, future goals and treatment is important to care. An expanded view of hope may assist when providing such information, including when discussing goals of care in the setting of advanced illness.

Social, psychological and existential well-being in patients with glioma and their caregivers: a qualitative study

BACKGROUND

Cerebral glioma has a devastating impact on cognitive, physical, social, psychological and spiritual well-being. We sought to understand the multidimensional experience of patients with this form of cancer as they progressed from receiving a diagnosis to the terminal phase of the disease.

METHODS

We recruited patients with a suspected brain tumour from a tertiary referral centre in the United Kingdom. We interviewed patients and their caregivers at key stages of the illness: before receiving a formal diagnosis, at the start of initial treatment, after initial treatment was completed and at six months' follow-up; caregivers were also interviewed postbereavement. We interviewed the patients' general practitioners once, after treatment had been completed. We transcribed the interviews and analyzed them thematically using the constant comparative method of a grounded theory approach.

RESULTS

We conducted in-depth interviews with 26 patients, 23 of their relatives and 19 general practitioners. We saw evidence of physical, social, psychological and existential distress even before a diagnosis was confirmed. Social decline followed a similar trajectory to that of physical decline, whereas psychological and existential distress were typically acute around diagnosis and again after initial treatment. Each patient's individual course varied according to other factors including the availability of support and individual and family resources (e.g., personal resilience and emotional support).

INTERPRETATION

There are practical ways that clinicians can care for patients with glioma and their caregivers, starting from before a diagnosis is confirmed. Understanding the trajectories of physical, social, psychological and existential well-being for these patients allows health care professionals to predict their patients' likely needs so they can provide appropriate support and sensitive and effective communication.

Palliative and end-of-life care in psychogeriatric patients

A rapidly growing number of elderly persons and their families are burdened by one or more terminal illnesses in the later years of their life. How best to support their quality of life is a major challenge for healthcare teams. Palliative and end-of-life (PEOL) care is well positioned to respond to this challenge. While the evidence of PEOL is just beginning, much of the suffering can be relieved by what is already known. PEOL care for the elderly needs to go beyond the focus on the patient and should rest on a broad understanding of the nature of suffering that includes family and professional caregivers in that experience of suffering. The dissemination of PEOL care principles should be a public health priority. This article aims to improve understanding of appropriate PEOL care in the elderly and discuss future perspectives.

Coping strategies in the presence of one's own impending death from cancer

An incurable cancer is a threat to life itself. This study focused on how native-born Swedes, who define themselves as nonreligious, actually reflect and act when they try to create helpful strategies in the presence of their own impending deaths and how the strategies serve their purposes. Twenty patients were interviewed in depth. The patients were enrolled in an advanced hospital-based home care team. The interviews were taped, transcribed and analyzed with a qualitative, hermeneutic interpretative method. The informants' efforts to develop useful strategies to restrain death could be symbolized as a cognitive and emotional pendulum, swinging between the extremes of life and death. During the swings of the pendulum, the informants used every means available: their own resources, other people, animals, nature, a transcendent power, hope, imagination and magical thinking. They strove to find factors that fitted their conceptual system and supported their inner balance and structure, all to keep death at a discreet distance and preserve their links to life. These links were togetherness, involvement, hope and continuance, and they served as a shield against hurtful feelings connected to their impending death. The new knowledge about how strategies in the presence of one's own impending death can develop and be used is perhaps the most novel and clinically relevant contribution of this study.

Level and direction of hope in cancer patients: an exploratory longitudinal study

GOALS

Hope is an important factor to consider when caring for cancer patients as a key component of coping with adversity. The aim of our study was to address the following questions: Is there a difference in level of hope between those patients being curatively and those palliatively treated, and how does this change over time? What are patients' most important hopes? Better understanding of patients' hopes may promote more effective patient-centered care.

MATERIALS AND METHODS

Outpatients referred to medical oncology or pain and symptom clinics at the London Regional Cancer Program were surveyed before consultation. The Herth Hope Index (HHI) questionnaire was administered to assess level of hope, and the patients were asked to indicate their highest priority hopes. Qualitative thematic analysis was performed on the responses, and comparison was made between patients treated with curative vs those treated with palliative intent. This survey was repeated 4 months after initial assessment.

RESULTS

Fifty patients were surveyed (29 curative-intent; 21 palliative). Highest priority initial hopes were categorized as follows: cure, other positive health outcomes, emotional well-being, life achievements/return to normalcy, interpersonal goals, other. There was no association noted between treatment intent and choice of highest-priority hope. Follow-up assessments after 4 months revealed no significant differences in the distribution pattern of hopes. There was a statistically significant increase in the HHI over time in curatively treated patients, but none in the combined analysis.

DISCUSSION AND CONCLUSION

Our study indicates that patients receiving palliative therapy have a HHI score not significantly different from patients being treated for cure. The hope deemed most important is also similar between groups. Over time, overall hope was maintained or increased even in the presence of a trend towards fewer patients hoping for a cure. These results remind oncologists to explore the experience of hope with all patients to ensure that the subjective needs and goals of the patients are met by the proposed therapies.

Measurement of psychological distress in palliative care

Research investigating the psychological distress of palliative care patients has contributed to our understanding of the needs and experiences of individuals approaching death. This paper aims to provide a brief review of such measurement of psychological distress in palliative care, focusing on established psychiatric and psychological research tools, and quantitative research methods. This includes clinical screening and diagnostic assessment instruments used to identify key distress-related symptoms and the presence of common clinical syndromes, such as depression, anxiety, delirium, as well as the broader psychological dimensions of suffering, such as existential concerns, spirituality, hope and demoralisation. There are important considerations in undertaking psychological research in palliative care, such as maintaining a balance between the methods and measurements that will address key research questions, and sensitivity to the range of physical and emotional demands facing individuals at the point of receiving palliative care. The clinical application of psychological and psychiatric research tools and methods can aid the detection of psychological distress, aid the thorough assessment of the psychological dimension of the patients' illness and care, aid the identification of individuals who would benefit from specific psychotherapeutic or pharmacologic interventions, and the evaluation of response to treatments.

End-of-Life Care for Older Adults

Caring for elderly patients and their families at the end of life gives physicians the opportunity to have a meaningful impact on the lives of others. By expanding our clinical expertise beyond the arena of cure and the preservation of life, we can discover new ways to encounter our patients as full human beings and to share a profound life passage that many of us might otherwise ignore. The skills that are needed to enter this new arena are well within the grasp of the office-based clinician, and physicians who employ them are rewarded with the fulfillment of knowing they have provided an invaluable service at a time of greatest need.
