Effect of dignity therapy on distress and end-of-life experience in terminally ill patients: a randomised controlled trial

BACKGROUND Dignity therapy is a unique, individualised, short-term psychotherapy that was developed for patients (and their families) living with life-threatening or life-limiting illness. We investigated whether dignity therapy could mitigate distress or bolster the experience in patients nearing the end of their lives. METHODS Patients (aged ≥18 years) with a terminal prognosis (life expectancy ≤6 months) who were receiving palliative care in a hospital or community setting (hospice or home) in Canada, USA, and Australia were randomly assigned to dignity therapy, client-centred care, or standard palliative care in a 1:1:1 ratio. Randomisation was by use of a computer-generated table of random numbers in blocks of 30. Allocation concealment was by use of opaque sealed envelopes. The primary outcomes--reductions in various dimensions of distress before and after completion of the study--were measured with the Functional Assessment of Chronic Illness Therapy Spiritual Well-Being Scale, Patient Dignity Inventory, Hospital Anxiety and Depression Scale, items from the Structured Interview for Symptoms and Concerns, Quality of Life Scale, and modified Edmonton Symptom Assessment Scale. Secondary outcomes of self-reported end-of-life experiences were assessed in a survey that was undertaken after the completion of the study. Outcomes were assessed by research staff with whom the participant had no previous contact to avoid any possible response bias or contamination. Analyses were done on all patients with available data at baseline and at the end of the study intervention. This study is registered with ClinicalTrials.gov, number NCT00133965. FINDINGS 165 of 441 patients were assigned to dignity therapy, 140 standard palliative care, and 136 client-centred care. 108, 111, and 107 patients, respectively, were analysed. No significant differences were noted in the distress levels before and after completion of the study in the three groups. For the secondary outcomes, patients reported that dignity therapy was significantly more likely than the other two interventions to have been helpful (χ(2)=35·50, df=2; p<0·0001), improve quality of life (χ(2)=14·52; p=0·001), increase sense of dignity (χ(2)=12·66; p=0·002), change how their family saw and appreciated them (χ(2)=33·81; p<0·0001), and be helpful to their family (χ(2)=33·86; p<0·0001). Dignity therapy was significantly better than client-centred care in improving spiritual wellbeing (χ(2)=10·35; p=0·006), and was significantly better than standard palliative care in terms of lessening sadness or depression (χ(2)=9·38; p=0·009); significantly more patients who had received dignity therapy reported that the study group had been satisfactory, compared with those who received standard palliative care (χ(2)=29·58; p<0·0001). INTERPRETATION Although the ability of dignity therapy to mitigate outright distress, such as depression, desire for death or suicidality, has yet to be proven, its benefits in terms of self-reported end-of-life experiences support its clinical application for patients nearing death.

The Patient Dignity Inventory: A Novel Way of Measuring Dignity-Related Distress in Palliative Care

Quality palliative care depends on a deep understanding of distress facing patients nearing death. Yet, many aspects of psychosocial, existential and spiritual distress are often overlooked. The aim of this study was to test a novel psychometric--the Patient Dignity Inventory (PDI)--designed to measure various sources of dignity-related distress among patients nearing the end of life. Using standard instrument development techniques, this study examined the face validity, internal consistency, test-retest reliability, factor structure and concurrent validity of the PDI. The 25-items of the PDI derive from a model of dignity in the terminally ill. To establish its basic psychometric properties, the PDI was administered to 253 patients receiving palliative care, along with other measures addressing issues identified within the Dignity Model in the Terminally Ill. Cronbachs coefficient alpha for the PDI was 0.93; the test-retest reliability was r = 0.85. Factor analysis resulted in a five-factor solution; factor labels include Symptom Distress, Existential Distress, Dependency, Peace of Mind, and Social Support, accounting for 58% of the overall variance. Evidence for concurrent validity was reported by way of significant associations between PDI factors and concurrent measures of distress. The PDI is a valid and reliable new instrument, which could assist clinicians to routinely detect end-of-life dignity-related distress. Identifying these sources of distress is a critical step toward understanding human suffering and should help clinicians deliver quality, dignity-conserving end-of-life care.

Predictors of Complicated Grief: A Systematic Review of Empirical Studies

A systematic review of the literature on predictors of complicated grief (CG) was undertaken with the aim of clarifying the current knowledge and to inform future planning and work in CG following bereavement. Predictors of CG prior to the death include previous loss, exposure to trauma, a previous psychiatric history, attachment style, and the relationship to the deceased. Factors associated with the death include violent death, the quality of the caregiving or dying experience, close kinship relationship to the deceased, marital closeness and dependency, and lack of preparation for the death. Perceived social support played a key role after death, along with cognitive appraisals and high distress at the time of the death. Inconsistent definitions of CG and measurement tools were noted in the earlier studies reviewed. Limitations identified in the studies included use of cross-sectional designs, heterogeneous samples, high attrition, demographic differences between cases and controls, differences in length of time since death, and differences in types of death experienced. Notwithstanding these limitations, some consistent findings have emerged. Further research into conceptualizations of CG in terms of attachment theory and constructivist and cognitive-behavioral concepts of finding purpose and meaning after bereavement is warranted.

Supportive and palliative care needs of families of children who die from cancer: an Australian study.

Objective To obtain feedback from parents of children who died from cancer about their understanding of palliative care, their experiences of palliative and supportive care received during their childs illness, and their palliative and supportive care needs. Design A qualitative study with semi-structured interviews. Participants: 24 parents from Perth (n = 10), Melbourne (n = 5), Brisbane (n = 5) and Sydney (n = 4). Setting: Five Australian tertiary paediatric oncology centres. Results Parents whose children died from cancer live within a context of chronic uncertainty and apprehension. Parents construed palliative care negatively as an independent process at the end of their childrens lives rather than as a component of a wider and continuous process where children and their families are offered both curative and palliative care throughout the cancer trajectory. The concept of palliative care was perceived to be misunderstood by key health professionals involved in the care of the child and family. The importance and therapeutic value of authentic and honest relationships between health professionals and parents, and between health professionals and children were highlighted as a critical aspect of care. Also highlighted was the need to include children and adolescents in decision making, and for the delivery of compassionate end-of-life care that is sensitive to the developmental needs of the children, their parents and siblings. Conclusions There is a need for health professionals to better understand the concept of palliative care, and factors that contribute to honest, open, authentic and therapeutic relationships of those concerned in the care of the dying child. This will facilitate a better understanding by both parents and their children with cancer, and acceptance of the integration of palliative and supportive care in routine cancer care.

Endocrine and immune responses to resistance training in prostate cancer patients

This study examined the effect of 20 weeks resistance training on a range of serum hormones and inflammatory markers at rest, and following acute bouts of exercise in prostate cancer patients undergoing androgen deprivation. Ten patients exercised twice weekly at high intensity for several upper and lower-body muscle groups. Neither testosterone nor prostate-specific antigen changed at rest or following an acute bout of exercise. However, serum growth hormone (GH), dehydroepiandrosterone (DHEA), interleukin-6, tumor necrosis factor-α and differential blood leukocyte counts increased (P<0.05) following acute exercise. Resistance exercise does not appear to compromise testosterone suppression, and acute elevations in serum GH and DHEA may partly underlie improvements observed in physical function.

The supportive and palliative care needs of Australian families of children who die from cancer

Objective To identify the perceptions of parents of children who died from cancer regarding the palliative and supportive care they received in hospital and in community settings. Method Face-to-face or telephone questionnaires. Setting Tertiary paediatric oncology centres in Western Australia, New South Wales, Queensland and Victoria. Participants 69 parents. Results Parents indicated the need for clear and honest information about their child’s condition and prognosis throughout the trajectory of illness. Parents also required access to, and advice from, multidisciplinary health professionals when caring for their child at home. Parents preferred to care for their child at home wherever possible throughout the palliative care trajectory of their child’s cancer and were well supported by immediate and extended family and friends. However, many families were affected emotionally and financially by the burden of caring for their child with incurable cancer. Families required financial and practical assistance with providing care from their child. Parents wanted and needed more practical resources and information to assist with the management of their child’s nutrition and pain, as well as for the support of their other children. Conclusion Care for children and their families should be coordinated by a multidisciplinary team in consultation with children and their families, and should be linked and integrated with the treating hospital in collaboration with community services.

A prospective evaluation of Dignity Therapy in advanced cancer patients admitted to palliative care

Background: Dignity Therapy is a brief, psychosocial intervention for patients with incurable disease. Aim: To investigate participation in and evaluation of Dignity Therapy and longitudinal changes in patient-rated outcomes. Design: A prospective (pre/post) evaluation design was employed. Evaluation questionnaires were completed when patients received the generativity document (T1) and 2 weeks later (T2). Changes from baseline (T0) were measured in sense of dignity, Structured Interview for Symptoms and Concerns items, Patient Dignity Inventory, Hospital Anxiety and Depression Scale and European Organisation for Research and Treatment of Cancer QLQ-C15-PAL (ClinicalTrials.gov number: NCT01507571). Setting/participants: Consecutive patients with incurable cancer, ≥18 years, informed of prognosis and not having cognitive impairment/physical limitations precluding participation were included at a hospice and a hospital palliative medicine unit. Results: Over 2 years, 80 of 341 eligible patients completed Dignity Therapy. At T1, 55 patients completed evaluations, of whom 73%–89% found Dignity Therapy helpful, satisfactory and of help to relatives; 47%–56% reported that it heightened their sense of purpose, dignity and will to live. Quality of life decreased (mean = −9 (95% confidence interval: −14.54; −2.49)) and depression increased (mean = 0.31 (0.06; 0.57)) on one of several depression measures. At T2 (n = 31), sense of dignity (mean = −0.52 (−1.01; −0.02)) and sense of being a burden to others (mean = −0.26 (−0.49; −0.02)) improved. Patients with children and lower performance status, emotional functioning and quality of life were more likely to report benefit. Conclusions: This study adds to the growing body of evidence supporting Dignity Therapy as a valuable intervention in palliative care; a substantial subset of patients facing end of life found it manageable, relevant and beneficial.

Dignity therapy: A feasibility study of elders in long-term care

OBJECTIVE The purpose of this study was to assess the feasibility of dignity therapy for the frail elderly. METHOD Participants were recruited from personal care units contained within a large rehabilitation and long-term care facility in Winnipeg, Manitoba. Two groups of participants were identified; residents who were cognitively able to directly take part in dignity therapy, and residents who, because of cognitive impairment, required that family member(s) take part in dignity therapy on their behalf. Qualitative and quantitative methods were applied in determining responses to dignity therapy from direct participants, proxy participants, and healthcare providers (HCPs). RESULTS Twelve cognitively intact residents completed dignity therapy; 11 cognitively impaired residents were represented in the study by way of family member proxies. The majority of cognitively intact residents found dignity therapy to be helpful; the majority of proxy participants indicated that dignity therapy would be helpful to them and their families. In both groups, HCPs reported the benefits of dignity therapy in terms of changing the way they perceived the resident, teaching them things about the resident they did not previously know; the vast majority indicated that they would recommend it for other residents and their families. SIGNIFICANCE OF RESULTS This study introduces evidence that dignity therapy has a role to play among the frail elderly. It also suggests that whether residents take part directly or by way of family proxies, the acquired benefits--and the effects on healthcare staff--make this area one meriting further study.

Enhancing palliative care delivery in a regional community in Australia

Although access to palliative care is a fundamental right for people in Australia and is endorsed by government policy, there is often limited access to specialist palliative care services in regional, rural and remote areas. This article appraises the evidence pertaining to palliative care service delivery to inform a sustainable model of palliative care that meets the needs of a regional population on the mid-north coast of New South Wales. Expert consultation and an eclectic literature review were undertaken to develop a model of palliative care service delivery appropriate to the needs of the target population and resources of the local community. On the basis of this review, a local palliative care system that is based on a population-based approach to service planning and delivery, with formalized integrated network agreements and role delineation between specialist and generalist providers, has the greatest potential to meet the palliative care needs of this regional coastal community.

Facilitating needs based cancer care for people with a chronic disease: evaluation of an intervention using a multi-centre interrupted time series design

BackgroundPalliative care should be provided according to the individual needs of the patient, caregiver and family, so that the type and level of care provided, as well as the setting in which it is delivered, are dependent on the complexity and severity of individual needs, rather than prognosis or diagnosis [1]. This paper presents a study designed to assess the feasibility and efficacy of an intervention to assist in the allocation of palliative care resources according to need, within the context of a population of people with advanced cancer.Methods/designPeople with advanced cancer and their caregivers completed bi-monthly telephone interviews over a period of up to 18 months to assess unmet needs, anxiety and depression, quality of life, satisfaction with care and service utilisation. The intervention, introduced after at least two baseline phone interviews, involved a) training medical, nursing and allied health professionals at each recruitment site on the use of the Palliative Care Needs Assessment Guidelines and the Needs Assessment Tool: Progressive Disease - Cancer (NAT: PD-C); b) health professionals completing the NAT: PD-C with participating patients approximately monthly for the rest of the study period. Changes in outcomes will be compared pre-and post-intervention.DiscussionThe study will determine whether the routine, systematic and regular use of the Guidelines and NAT: PD-C in a range of clinical settings is a feasible and effective strategy for facilitating the timely provision of needs based care.Trials registrationISRCTN21699701
