Dying from cancer: results of a national population-based investigation

Dying Patients' Quality of Care for Five Common Causes of Death: A Nationwide Mortality Follow-Back Survey

Background: The importance of high-quality care for terminal patients is being increasingly recognized; however, quality of care (QOC) and quality of death and dying (QOD) for noncancer patients remain unclear. Objectives: To clarify QOC and QOD according to places and causes of death. Design, Subjects: A nationwide mortality follow-back survey was conducted using death certificate data for cancer, heart disease, stroke syndrome, pneumonia, and kidney failure in Japan. The questionnaire was distributed to 115,816 bereaved family members between February 2019 and February 2020. Measurements included QOC, QOD, and symptoms during the last week of life. Analyses used generalized estimating equations adjusting for age, sex, and region. Results: Valid responses were returned by 62,576 (54.0%). Family-reported QOC and QOD by the place of death were significantly higher at home than in other places across all causes of death (for all combinations with hospital p < 0.01). In stroke syndrome and pneumonia, QOD significantly differed between hospital and home (stroke syndrome: 57.1 vs. 72.4, p < 0.001, effect size 0.77; pneumonia: 57.3 vs. 71.1, p < 0.001, effect size 0.78). No significant differences were observed in QOC and QOD between cancer and noncancer. The prevalence of symptoms was higher for cancer than for other causes of death. Conclusions: QOC and QOD were higher at home than in other places of death across all causes of death. The further expansion of end-of-life care options is crucial for improving QOC and QOD for all terminal patients.

Prevalence of cognitive impairment following chemotherapy treatment for breast cancer: a systematic review and meta-analysis

Breast cancer survival rates have markedly improved. Consequently, survivorship issues have received increased attention. One common sequel of treatment is chemotherapy-induced cognitive impairment (CICI). CICI causes a range of impairments that can have a significant negative impact on quality of life. Knowledge of the prevalence of this condition is required to inform survivorship plans, and ensure adequate resource allocation and support is available for sufferers, hence a systematic review of prevalence data was performed. Medline, Scopus, CINAHL and PSYCHInfo were searched for eligible studies which included prevalence data on CICI, as ascertained though the use of self-report, or neuropsychological tests. Methodological quality of included studies was assessed. Findings were synthesised narratively, with meta-analyses being used to calculate pooled prevalence when impairment was assessed by neuropsychological tests. The review included 52 studies. Time-points considered ranged from the chemotherapy treatment period to greater than 10 years after treatment cessation. Summary prevalence figures (across time-points) using self-report, short cognitive screening tools and neuropsychological test batteries were 44%, 16% and 21–34% respectively (very low GRADE evidence). Synthesised findings demonstrate that 1 in 3 breast cancer survivors may have clinically significant cognitive impairment. Prevalence is higher when self-report based on patient experience is considered. This review highlights a number of study design issues that may have contributed to the low certainty rating of the evidence. Future studies should take a more consistent approach to the criteria used to assess impairment. Larger studies are urgently needed.

A Population-Based Mortality Follow-Back Survey Evaluating Good Death for Cancer and Noncancer Patients: A Randomized Feasibility Study

CONTEXT

Evaluation of end-of-life care is a key element in quality improvement, and population-based mortality follow-back designs have been used in several countries. This design was adapted to evaluate a good death in Japan.

OBJECTIVES

This study aimed to explain the scientific background and rationale for assessing the feasibility of a mortality follow-back survey using a randomized design.

DESIGN

We used a cross-sectional questionnaire survey to assess feasibility using response rate, sample representativeness, effect on response rate with two methods, and survey acceptability.

SETTING/PARTICIPANTS

The subjects were 4812 bereaved family members of patients who died from the major five causes of death: cancer, heart disease, cerebrovascular disease, pneumonia, or kidney failure, using mortality data.

RESULTS

Overall, 682 (14.2%) questionnaires could not be delivered, and 2294 (55.5%) family members agreed to participate in the survey. There was little difference in the distribution of characteristics between the study subjects and the full population, and sample representativeness was acceptable. Sending the questionnaire with a pen achieved a higher response rate than without (weighted: 48.2% vs. 40.8%; P < 0.001). In follow-up contact, there was no difference in response rate between resending the questionnaire and a reminder letter alone (weighted: 32.9% vs. 32.4%; P = 0.803). In total, 84.8% (weighted) of the participants agreed with improving quality of care through this kind of survey.

CONCLUSION

This study demonstrated the feasibility of conducting a population-based mortality follow-back survey using a randomized design. An attached pen with the questionnaire was effective in improving the response rate.

Role of Hospice Care at the End of Life for People With Cancer

Patient-defined factors that are important at the end of life include being physically independent for as long as possible, good symptom control, and spending quality time with friends and family. Hospice care adds to the quality of care and these patient-centered priorities for people with cancer and their families in the last weeks and days of life. Evidence from large observational studies demonstrate that hospice care can improve outcomes directly and support better and more appropriate health care use for people in the last stages of cancer.

Team-based community hospice care has measurable benefits for patients, their family caregivers, and health services. In addition to improved symptom control for patients and a greater likelihood of time spent at home, caregiver outcomes are better when hospice care is accessed: informational needs are better met, and caregivers have an improved ability to move on with life after the patient’s death compared with people who did not have access to these services.

Hospice care continues to evolve as its reach expands and the needs of patients continue to broaden. This is reflected in the transition from hospice being based on excellence in nursing to teams with a broad range of health professionals to meet the complex and changing needs of patients and their families. Additional integration of cancer services with hospice care will help to provide more seamless care for patients and supporting family caregivers during their caregiving and after the death of the patient.

Systematic Review of the Prevalence, Predictors, and Treatment of Insomnia in Palliative Care

Introduction:

The primary function of palliative care is to improve quality of life. The recognition and treatment of symptoms causing suffering is central to the achievement of this goal. Insomnia reduces quality of life of patients under palliative care. Knowledge about prevalence, associated factors, and treatment of insomnia in palliative care is scarce.

Methodology:

Literature review about the prevalence, predictors, and treatment options of insomnia in palliative care patients. Primary sources of investigation were identified and selected through Pubmed and Scopus databases. The research was complemented by reference search in identified articles and selected reviews. OpenGrey and Google Scholar were used for searching grey literature. Study quality analysis was based on the Newcastle-Ottawa Scale.

Results:

A total of 65 studies were included in the review. Most studies had acceptable /good quality. The prevalence of insomnia in the included studies ranged from 2.1% to 100%, with a median overall prevalence of 49.5%. Sociodemographic factors such as age; clinical characteristics such as functional status, disease stage, pain, and use of specific drugs, including opioids; psychological factors such as anxiety/depression; and spiritual factors such as feelings of well-being were identified as predictors. The treatment options identified were biological (pharmacological and nonpharmacological), psychological (visualization, relaxation), and spiritual (prayer).

Conclusions:

The systematic review showed that the prevalence of insomnia is high, with at least one in 3 patients affected in most studies. Insomnia’s risk factors and treatment in palliative care are both associated to physical, psychological, social, and spiritual factors, reflecting its true holistic nature.

Palliative Care and the Management of Common Distressing Symptoms in Advanced Cancer: Pain, Breathlessness, Nausea and Vomiting, and Fatigue

Good symptom management in oncology is associated with improved patient and family quality of life, greater treatment compliance, and may even offer survival advantages. With population growth and aging, the proportion of patients with multiple symptoms—both related and unrelated to their cancer—is anticipated to increase, supporting calls for a more routine and integrated approach to symptom management. This article presents a summary of the literature for the use of symptom assessment tools and reviews the management of four common and distressing symptoms commonly experienced by people with advanced cancer: pain, breathlessness, nausea and vomiting, and fatigue. We also discuss the role of palliative care in supporting a holistic approach to symptom management throughout the cancer trajectory.

A Video Decision Aid Improves Informed Decision Making in Patients With Advanced Cancer Considering Palliative Radiation Therapy

CONTEXT

Advanced cancer patients have unrecognized gaps in their understanding about palliative radiation therapy (PRT).

OBJECTIVES

To build a video decision aid for hospitalized patients with advanced cancer referred for PRT and prospectively test its efficacy in reducing decisional uncertainty, improving knowledge, increasing treatment readiness and readiness for palliative care consultation, and its acceptability among patients.

METHODS

Forty patients with advanced cancer hospitalized at Memorial Sloan Kettering Cancer Center watched a video decision aid about PRT and palliative care. Patients' conceptual and logistical knowledge of PRT, decisional uncertainty, treatment readiness, and readiness for palliative care consultation were assessed before and after watching the video with a six-item knowledge survey, the decisional uncertainty subscale of the Decisional Conflict Scale, and Likert instruments to assess readiness to accept radiation treatment and/or palliative care consultation, respectively. A postvideo survey assessed the video's acceptability among patients.

RESULTS

After watching the video, decisional uncertainty was reduced (28.3 vs. 21.7; P = 0.02), knowledge of PRT improved (60.4 vs. 88.3; P < 0.001), and PRT readiness increased (2.0 vs. 1.3; P = 0.04). Readiness for palliative care consultation was unchanged (P = 0.58). Patients felt very comfortable (70%) watching the video and would highly recommend it (75%) to others.

CONCLUSION

Among hospitalized patients with advanced cancer, a video decision aid reduced decisional uncertainty, improved knowledge of PRT, increased readiness for PRT, and was well received by patient viewers.

Factors which Influence Coping: Home-based Family Caregiving of Persons with Advanced Cancer

The findings from a qualitative study of bow caregivers coped while they cared for a dying family member at home are presented. Fifteen family caregivers were interviewed twice following The death of their family member. Although it was not one of the original objectives of the research, coping emerged as a category needing further analysis. There were factors that either facilitated or interfered with caregiver coping. Those factors that facilitated their coping included characteristics of the caregivers themselves; contributions made by the dying person; and supportive networks, both formal and informal, available to the caregivers. Interfering factors related to caregiver experiences with informal and formal systems. From the more distant Perspective of post-death reflections, the caregivers Provided insight into how their coping was grounded in the meaning associated with their experiences.

Receiving Bad News: Experiences of Family Members

Little is known about how next-of-kin experience receiving bad news. The aim of this study was to explore the experiences of family members when receiving information about ending tumour treatment, with a focus on their role in this context.

Methods

Semi-structured interviews were performed and analyzed using a qualitative phenomenographic method.

Results

Twenty family members of patients with incurable progressive cancer admitted to hospital-based home care were included in the study. Data showed that family members want to protect, represent, or act on behalf of the patient. Some described themselves as assuming prominent roles: the demander-of-truth role, the secret-keeper role, and the controller role. Others assumed more passive roles: the surrendering role, the considerate listener role, and the excluded outsider role.

Conclusion

This study has revealed possible explanations as to why family members are dissatisfied with information. The results of this study may help doctors in clinical practice recognize the different types of behaviour family members exhibit when receiving bad news.

The nature of nausea: prevalence, etiology, and treatment in patients with advanced cancer not receiving antineoplastic treatment

BACKGROUND

The prevalence of nausea/vomiting in patients with advanced cancer has a wide range. Due to a very low level of evidence regarding antiemetic treatment, current guidelines recommend an etiology-based approach. The evidence for this approach is also slim and research is urgently needed.

OBJECTIVES

(Part One) to elucidate the prevalence of nausea and the possible associations with sociodemographic and clinical variables and (Part Two) to investigate possible etiologies of nausea and antiemetic treatments initiated in patients with nausea.

METHODS

Patients with advanced cancer and no recent antineoplastic treatment were included in a prospective two-part study. In Part One, patients completed an extended version of the EORTC QLQ-C15-PAL. Nauseated patients could then be included in Part Two in which possible etiologies and antiemetic treatment were recorded and a follow-up questionnaire was completed.

RESULTS

Eight hundred twenty-one patients were included and 46% reported any degree of nausea. Younger age and female sex were associated with a higher degree of nausea. Common etiologies included constipation, opioid use, and "other," and treatments associated with a statistically significant decrease in nausea/vomiting were olanzapine, laxatives, corticosteroids, domperidone, and metoclopramide.

CONCLUSION

Nausea was a common symptom in this patient population and many different etiologies were suggested. Most patients reported a lower degree of nausea at follow-up. More research in treatment approaches and specific antiemetics is strongly needed.

A Palliative Radiation Oncology Consult Service's Impact on Care of Advanced Cancer Patients

INTRODUCTION

Palliative radiation therapy (PRT) is a commonly utilized intervention for symptom palliation among patients with metastatic cancer, yet it is under-recognized as a distinct area of subspecialty within radiation oncology.

OBJECTIVE

We developed a multidisciplinary service model within radiation oncology called the Palliative Radiation Oncology Consult (PROC) service to improve the quality of cancer care for advanced cancer patients. We assessed the service's impact on patient-related and healthcare utilization outcomes.

DESIGN

Patients were included in this observational cohort study if they received PRT at a single tertiary care hospital between 2009 and 2017. We compared outcomes of patients treated after (post-intervention group) to those treated before (control group) PROC's establishment using unadjusted and propensity score adjusted analyses.

RESULTS

Of the 450 patients in the cohort, 154 receive PRT pre- and 296 after PROC's establishment. In comparison to patients treated pre-PROC, post-PROC patients were more likely to undergo single-fraction radiation (RR: 7.74, 95% CI: 3.84-15.57) and hypofraction (2-5 fraction) radiation (RR: 10.74, 95% CI: 5.82-19.83), require shorter hospital stays (21 vs. 26.5 median days, p = 0.01), and receive more timely specialty-level palliative care (OR: 2.65, 95% CI: 1.56-4.49). Despite shortened treatments, symptom relief was similar (OR: 1.35, 95% CI: 0.80-2.28).

CONCLUSION

The PROC service was associated with more efficient radiation courses, substantially reduced hospital length of stays, and more timely palliative care consultation, without compromising symptom improvements. These results suggest that a multidisciplinary care delivery model can lead to enhanced quality of care for advanced cancer patients.

Community Hospitals: an Under-Recognized Resource for Palliative Care

In the UK there are concerns that, in certain groups of dying patients such as the old, those with non-cancer diagnoses and those in rural areas, the quality of care is unacceptably variable. There has been no systematic survey of the extent to which community hospitals provide general palliative care for such patients. Therefore, by means of a structured questionnaire we asked senior nurses/managers at all 478 community hospitals in the UK for information on staff expertise, facilities and specialist equipment, liaison arrangements with specialist palliative care providers, priorities, practice and policy in end-of-life care. Of the 346 hospitals (72%) that responded, only 28 were in urban areas. 73% of hospitals employed at least one nurse with additional training in palliative care, 72% had access to 24-hour specialist palliative care advice and 51% had separate overnight accommodation for relatives, but only 22% had designated palliative care beds. Most hospitals did not have written policies or guidelines for patient assessment or symptom control. These findings add to evidence that community hospitals represent an important resource to improve access to palliative care for groups that are currently under-served.

Early palliative care for adults with advanced cancer

BACKGROUND

Incurable cancer, which often constitutes an enormous challenge for patients, their families, and medical professionals, profoundly affects the patient's physical and psychosocial well-being. In standard cancer care, palliative measures generally are initiated when it is evident that disease-modifying treatments have been unsuccessful, no treatments can be offered, or death is anticipated. In contrast, early palliative care is initiated much earlier in the disease trajectory and closer to the diagnosis of incurable cancer.

OBJECTIVES

To compare effects of early palliative care interventions versus treatment as usual/standard cancer care on health-related quality of life, depression, symptom intensity, and survival among adults with a diagnosis of advanced cancer.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, OpenGrey (a database for grey literature), and three clinical trial registers to October 2016. We checked reference lists, searched citations, and contacted study authors to identify additional studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and cluster-randomised controlled trials (cRCTs) on professional palliative care services that provided or co-ordinated comprehensive care for adults at early advanced stages of cancer.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane. We assessed risk of bias, extracted data, and collected information on adverse events. For quantitative synthesis, we combined respective results on our primary outcomes of health-related quality of life, survival (death hazard ratio), depression, and symptom intensity across studies in meta-analyses using an inverse variance random-effects model. We expressed pooled effects as standardised mean differences (SMDs, or Hedges' adjusted g). We assessed certainty of evidence at the outcome level using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) and created a 'Summary of findings' table.

MAIN RESULTS

We included seven randomised and cluster-randomised controlled trials that together recruited 1614 participants. Four studies evaluated interventions delivered by specialised palliative care teams, and the remaining studies assessed models of co-ordinated care. Overall, risk of bias at the study level was mostly low, apart from possible selection bias in three studies and attrition bias in one study, along with insufficient information on blinding of participants and outcome assessment in six studies.Compared with usual/standard cancer care alone, early palliative care significantly improved health-related quality of life at a small effect size (SMD 0.27, 95% confidence interval (CI) 0.15 to 0.38; participants analysed at post treatment = 1028; evidence of low certainty). As re-expressed in natural units (absolute change in Functional Assessment of Cancer Therapy-General (FACT-G) score), health-related quality of life scores increased on average by 4.59 (95% CI 2.55 to 6.46) points more among participants given early palliative care than among control participants. Data on survival, available from four studies enrolling a total of 800 participants, did not indicate differences in efficacy (death hazard ratio 0.85, 95% CI 0.56 to 1.28; evidence of very low certainty). Levels of depressive symptoms among those receiving early palliative care did not differ significantly from levels among those receiving usual/standard cancer care (five studies; SMD -0.11, 95% CI -0.26 to 0.03; participants analysed at post treatment = 762; evidence of very low certainty). Results from seven studies that analysed 1054 participants post treatment suggest a small effect for significantly lower symptom intensity in early palliative care compared with the control condition (SMD -0.23, 95% CI -0.35 to -0.10; evidence of low certainty). The type of model used to provide early palliative care did not affect study results. One RCT reported potential adverse events of early palliative care, such as a higher percentage of participants with severe scores for pain and poor appetite; the remaining six studies did not report adverse events in study publications. For these six studies, principal investigators stated upon request that they had not observed any adverse events.

AUTHORS' CONCLUSIONS

This systematic review of a small number of trials indicates that early palliative care interventions may have more beneficial effects on quality of life and symptom intensity among patients with advanced cancer than among those given usual/standard cancer care alone. Although we found only small effect sizes, these may be clinically relevant at an advanced disease stage with limited prognosis, at which time further decline in quality of life is very common. At this point, effects on mortality and depression are uncertain. We have to interpret current results with caution owing to very low to low certainty of current evidence and between-study differences regarding participant populations, interventions, and methods. Additional research now under way will present a clearer picture of the effect and specific indication of early palliative care. Upcoming results from several ongoing studies (N = 20) and studies awaiting assessment (N = 10) may increase the certainty of study results and may lead to improved decision making. In perspective, early palliative care is a newly emerging field, and well-conducted studies are needed to explicitly describe the components of early palliative care and control treatments, after blinding of participants and outcome assessors, and to report on possible adverse events.

Eating-related distress and need for nutritional support of families of advanced cancer patients: a nationwide survey of bereaved family members

BACKGROUND

A number of advanced cancer patients are suffering from physical and psychosocial burdens because of cancer cachexia, and these burdens also greatly impact on their family members and relationships between patients and family members. It is necessary to consider the psychosocial impact of cancer cachexia on family members of advanced cancer patients.

METHODS

A cross-sectional anonymous nationwide survey was conducted involving 925 bereaved family members of cancer patients who had been admitted to 133 inpatient hospices throughout Japan.

RESULTS

A total of 702 bereaved family members returned the questionnaires (response rate, 75.9%). Concerning eating-related distress, 'I served what the patient wanted without consideration of calories and nutritional composition' was highest (75.1%), and 'I tried making many kinds of meals for the patient' and 'I was concerned about planning meals for the patient every day' followed (63.0% and 59.4%, respectively). The top 5 of the 19 items were categorized as 'fighting back'. Need for nutritional support was high (72.2%), and need for explanations about the reasons for anorexia and weight loss of patients was moderate (41.4%). Explanatory factor analysis of eating-related distress identified the following four domains: (factor 1) feeling that family members forced the patient to eat to avoid death, (factor 2) feeling that family members made great efforts to help the patient eat, (factor 3) feeling that eating was a cause of conflicts between the patient and family members, and (factor 4) feeling that correct information was insufficient. Results of multiple logistic regression analysis showed that spouse, fair/poor mental status, factors 1, and 4 were identified as independent determinants of major depression {odds ratio [OR] 3.27 [95% confidence interval (CI) 1.24-8.60], P = 0.02; OR 4.50 [95% CI 2.46-8.25], P < 0.001; OR 2.51 [95% CI 1.16-5.45], P = 0.02; OR 2.33 [95% CI 1.13-4.80], P = 0.02, respectively}.

CONCLUSIONS

A number of family members of advanced cancer patients experienced high levels of eating-related distress and had a need for nutritional support.

The health care experience of patients with cancer during the last year of life: Analysis of the SEER-CAHPS data set

BACKGROUND

Providing high-quality medical care for individuals with cancer during their last year of life involves a range of challenges. An important component of high-quality care during this critical period is ensuring optimal patient satisfaction. The objective of the current study was to assess factors influencing health care ratings among individuals with cancer within 1 year before death.

METHODS

The current study used the Surveillance, Epidemiology, and End Results (SEER)-Consumer Assessment of Healthcare Providers and Systems (CAHPS) data set, a new data resource linking patient-reported information from the CAHPS Medicare Survey with clinical information from the National Cancer Institute's SEER program. The study included 5102 Medicare beneficiaries diagnosed with cancer who completed CAHPS between 1998 and 2011 within 1 year before their death. Multivariable logistic regression analyses examined associations between patient demographic and insurance characteristics with 9 measures of health care experience.

RESULTS

Patients with higher general or mental health status were significantly more likely to indicate excellent experience with nearly all measures examined. Sex, race/ethnicity, and education also were found to be significant predictors for certain ratings. Greater time before death predicted an increased likelihood of higher ratings for health plan and specialist physician. Clinical characteristics were found to have few significant associations with experience of care. Individuals in fee-for-service Medicare plans (vs Medicare Advantage) had a greater likelihood of excellent experience with health plans, getting care quickly, and getting needed care.

CONCLUSIONS

Among patients with cancer within 1 year before death, experience with health plans, physicians, and medical care were found to be associated with sociodemographic, insurance, and clinical characteristics. These findings provide guidance for the development of programs to improve the experience of care among individuals with cancer. Cancer 2017;123:336-344. © 2016 American Cancer Society.

Factors Associated with Transition from Community Settings to Hospital as Place of Death for Adults Aged 75 and Older: A Population-Based Mortality Follow-Back Survey

Objectives

To identify factors associated with end‐of‐life (EoL) transition from usual place of care to the hospital as place of death for people aged 75 and older.

Design

Population‐based mortality follow‐back survey.

Setting

Deaths over 6 months in 2012 in two unitary authorities in England covering 800 square miles with more than 1 million residents.

Participants

A random sample of people aged 75 and older who died in a care home or hospital and all those who died at home or in a hospice unit (N = 882). Cases were identified from death registrations. The person who registered the death (a relative for 98.9%) completed the survey.

Measurements

The main outcome was EoL transition to the hospital as place of death versus no EoL transition to the hospital. Multivariable modified Poisson regression was used to examine factors (illness, demographic, environmental) related to EoL transition to the hospital.

Results

Four hundred forty‐three (50.2%) individuals responded, describing the care of the people who died. Most died from nonmalignant conditions (76.3%) at a mean age of 87.4 ± 6.4. One hundred forty‐six (32.3%) transitioned to the hospital and died there. Transition was more likely for individuals with respiratory disease than for those with cancer (prevalence ratio (PR) = 2.07, 95% confidence interval (CI) = 1.42–3.01) and for people with severe breathlessness (PR = 1.96, 95% CI = 1.12–3.43). Transition was less likely if EoL preferences had been discussed with a healthcare professional (PR = 0.60, 95% CI = 0.42–0.88) and when there was a key healthcare professional (PR = 0.74, 95% CI = 0.58–0.95).

Conclusion

To reduce EoL transition to the hospital for older people, there needs to be improved management of breathlessness in the community and better access to a key healthcare professional skilled in coordinating care, communication, facilitating complex discussions, and in planning for future care.

Integrating Palliative Care: A Postmodern Perspective

Hospice and palliative care philosophy is becoming increasingly incorporated into medical practice, education, and research. However, this process of integration may be hindered by continued adherence to several perceived conceptual dichotomies: natural and medicalized death, research and clinical care, and acceptance and denial of dying. These dichotomies were perhaps essential for the initial development of palliative care but could undermine the continuing evolution of care for the terminally ill. In this article, the authors deconstruct these dichotomies and advocate for a fully integrated model of palliative care.

Non-pharmacological interventions for cognitive impairment due to systemic cancer treatment

BACKGROUND

It is estimated that up to 75% of cancer survivors may experience cognitive impairment as a result of cancer treatment and given the increasing size of the cancer survivor population, the number of affected people is set to rise considerably in coming years. There is a need, therefore, to identify effective, non-pharmacological interventions for maintaining cognitive function or ameliorating cognitive impairment among people with a previous cancer diagnosis.

OBJECTIVES

To evaluate the cognitive effects, non-cognitive effects, duration and safety of non-pharmacological interventions among cancer patients targeted at maintaining cognitive function or ameliorating cognitive impairment as a result of cancer or receipt of systemic cancer treatment (i.e. chemotherapy or hormonal therapies in isolation or combination with other treatments).

SEARCH METHODS

We searched the Cochrane Centre Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PUBMED, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and PsycINFO databases. We also searched registries of ongoing trials and grey literature including theses, dissertations and conference proceedings. Searches were conducted for articles published from 1980 to 29 September 2015.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of non-pharmacological interventions to improve cognitive impairment or to maintain cognitive functioning among survivors of adult-onset cancers who have completed systemic cancer therapy (in isolation or combination with other treatments) were eligible. Studies among individuals continuing to receive hormonal therapy were included. We excluded interventions targeted at cancer survivors with central nervous system (CNS) tumours or metastases, non-melanoma skin cancer or those who had received cranial radiation or, were from nursing or care home settings. Language restrictions were not applied.

DATA COLLECTION AND ANALYSIS

Author pairs independently screened, selected, extracted data and rated the risk of bias of studies. We were unable to conduct planned meta-analyses due to heterogeneity in the type of interventions and outcomes, with the exception of compensatory strategy training interventions for which we pooled data for mental and physical well-being outcomes. We report a narrative synthesis of intervention effectiveness for other outcomes.

MAIN RESULTS

Five RCTs describing six interventions (comprising a total of 235 participants) met the eligibility criteria for the review. Two trials of computer-assisted cognitive training interventions (n = 100), two of compensatory strategy training interventions (n = 95), one of meditation (n = 47) and one of physical activity intervention (n = 19) were identified. Each study focused on breast cancer survivors. All five studies were rated as having a high risk of bias. Data for our primary outcome of interest, cognitive function were not amenable to being pooled statistically. Cognitive training demonstrated beneficial effects on objectively assessed cognitive function (including processing speed, executive functions, cognitive flexibility, language, delayed- and immediate- memory), subjectively reported cognitive function and mental well-being. Compensatory strategy training demonstrated improvements on objectively assessed delayed-, immediate- and verbal-memory, self-reported cognitive function and spiritual quality of life (QoL). The meta-analyses of two RCTs (95 participants) did not show a beneficial effect from compensatory strategy training on physical well-being immediately (standardised mean difference (SMD) 0.12, 95% confidence interval (CI) -0.59 to 0.83; I(2)= 67%) or two months post-intervention (SMD - 0.21, 95% CI -0.89 to 0.47; I(2) = 63%) or on mental well-being two months post-intervention (SMD -0.38, 95% CI -1.10 to 0.34; I(2) = 67%). Lower mental well-being immediately post-intervention appeared to be observed in patients who received compensatory strategy training compared to wait-list controls (SMD -0.57, 95% CI -0.98 to -0.16; I(2) = 0%). We assessed the assembled studies using GRADE for physical and mental health outcomes and this evidence was rated to be low quality and, therefore findings should be interpreted with caution. Evidence for physical activity and meditation interventions on cognitive outcomes is unclear.

AUTHORS' CONCLUSIONS

Overall, the, albeit low-quality evidence may be interpreted to suggest that non-pharmacological interventions may have the potential to reduce the risk of, or ameliorate, cognitive impairment following systemic cancer treatment. Larger, multi-site studies including an appropriate, active attentional control group, as well as consideration of functional outcomes (e.g. activities of daily living) are required in order to come to firmer conclusions about the benefits or otherwise of this intervention approach. There is also a need to conduct research into cognitive impairment among cancer patient groups other than women with breast cancer.

A Comprehensive Approach to the Patient at End of Life: Assessment of Multidimensional Suffering

Pain is a multidimensional, complex experience. There are many challenges in identifying and meeting the needs of patients experiencing pain. Evaluation of pain from a bio-psycho-social-spiritual framework is particularly germane for patients approaching the end of life. This review explores the relation between the psychospiritual dimensions of suffering and the experience of physical pain, and how to assess and treat pain in a multidimensional framework. A review of empirical data on the relation between pain and suffering as well as interdisciplinary evidence-based approaches to alleviate suffering are provided.

“Am I Going to Die Now?” Prognostication of Survival Time by Members of the Care Team

To get a real chance to make autonomous decisions in the final phase of their life, people who are soon going to die have a right to be informed concerning available knowledge about their prognosis and condition. The aim of this study is to describe how different members of the care team make prognostications about patients' survival time, and what motivates their prognostications. Doctors and registered nurses made prognostications to a greater extent, and were also somewhat more successful, than practical nurses and social workers. Different professions seem to differ in some respects concerning the criteria included in their motivations and the knowledge upon which they base their motivations.

Population-Based Quality Indicators for Palliative Care Programs for Cancer Patients in Japan: A Delphi Study

CONTEXT

Cancer control programs in Japan strongly endorse the dissemination of palliative care, and various policy measures have been implemented; however, indicators for evaluating palliative care programs have not been defined.

OBJECTIVES

The aim of this study was to develop quality indicators for palliative care programs taking a population-based view to meet the challenge of cancer control in the Japanese population.

METHODS

We conducted a modified Delphi survey. The panelists rated a list of indicators over three iterative rounds according to four perspectives: 1) consistency with the policy target, 2) relevance to the problem, 3) clarity of expression, and 4) measurement feasibility. The criterion for adoption of candidate indicators was set at a total mean score of 7 or more. Finally, the most relevant and important indicators were selected; consensus was defined by agreement of panelists at the panel meeting.

RESULTS

Among 49 panelists surveyed, 48 (98%), 39 (80%), and 43 (88%) responded over the three rounds, respectively. The 15 indicators were identified from 11 domains: patient-reported quality of life, bereaved family-reported quality at the end of life, family care, place of death, bereaved family-reported quality of palliative care, specialized palliative care services, opioid utilization, public perceptions about palliative care, palliative care education to primary care providers, specialist palliative care services, and regional palliative care.

CONCLUSION

Comprehensive quality indicators for palliative care programs were identified. The indicators are currently being used, and the feasibility of measuring change over time will be examined. It is expected that the indicators will be used effectively in the future. It is important to evaluate outcomes of the program, to improve weaknesses, improve outcomes, and promote the welfare of cancer patients.

The importance of measuring customer satisfaction in palliative care

In the last decades, palliative care has been more and more focused on the evaluation of patients' and families' satisfaction with care. However, the evaluation of customer satisfaction in palliative care presents a number of issues such as the presence of both patients and their families, the frail condition of the patients and the complexity of their needs, and the lack of standard quality indicators and appropriate measurement tools. In this manuscript, we critically review existing evidence and literature on the evaluation of satisfaction in the palliative care context. Moreover, we provide - as a practical example - the preliminary results of our experience in this setting with the development of a dedicated tool for the measurement of satisfaction.

Measuring Experience With End-of-Life Care: A Systematic Literature Review

CONTEXT

Increasing interest in end-of-life care has resulted in many tools to measure the quality of care. An important outcome measure of end-of-life care is the family members' or caregivers' experiences of care.

OBJECTIVES

To evaluate the instruments currently in use to inform next steps for research and policy in this area.

METHODS

We conducted a systematic review of PubMed, PsycINFO, and PsycTESTS(®) for all English-language articles published after 1990 using instruments to measure adult patient, family, or informal caregiver experiences with end-of-life care. Survey items were abstracted and categorized into content areas identified through an iterative method using three independent reviewers. We also abstracted information from the most frequently used surveys about the identification of proxy respondents for after-death surveys, the timing and method of survey administration, and the health care setting being assessed.

RESULTS

We identified 88 articles containing 51 unique surveys with available content. We characterized 14 content areas variably present across the 51 surveys. Information and care planning, provider care, symptom management, and overall experience were the most frequent areas addressed. There was also considerable variation across the surveys in the identification of proxy respondents, the timing of survey administration, and in the health care settings and services being evaluated.

CONCLUSION

This review identified several comprehensive surveys aimed at measuring the experiences of end-of-life care, covering a variety of content areas and practical issues for survey administration. Future work should focus on standardizing surveys and administration methods so that experiences of care can be reliably measured and compared across care settings.

Development and characterisation of novel fentanyl-delta opioid receptor antagonist based bivalent ligands

BACKGROUND

Opioid tolerance is a limiting factor in chronic pain. Delta opioid peptide (DOP)(δ) receptor antagonism has been shown to reduce tolerance. Here, the common clinical mu opioid peptide (MOP)(µ) receptor agonist fentanyl has been linked to the DOP antagonist Dmt-Tic (2',6'-dimethyl-L-tyrosyl-1,2,3,4-tetrahydrisoquinoline-3-carboxylic acid) to create new bivalent compounds.

METHODS

Binding affinities of bivalents(#9, #10, #11, #12 and #13) were measured in Chinese hamster ovary (CHO) cells expressing recombinant human MOP, DOP, Kappa opioid peptide (KOP)(κ) and nociceptin/orphanin FQ opioid peptide (NOP) receptors. Functional studies, measuring GTPγ[(35)S] or β-arrestin recruitment, were performed in membranes or whole cells respectively expressing MOP and DOP.

RESULTS

The new bivalents bound to MOP (pKi : #9:7.31; #10:7.58; #11:7.91; #12:7.94; #13:8.03) and DOP (#9:8.03; #10:8.16; #11:8.17; #12:9.67; #13:9.71). In GTPγ[(35)S] functional assays, compounds #9(pEC50:6.74; intrinsic activity:0.05) #10(7.13;0.34) and #11(7.52;0.27) showed weak partial agonist activity at MOP. Compounds #12 and #13, with longer linkers, showed no functional activity at MOP. In antagonist assays at MOP, compounds #9 (pKb:6.87), #10(7.55) #11(7.81) #12(6.91) and #13(7.05) all reversed the effects of fentanyl. At DOP, all compounds showed antagonist affinity (#9:6.85; #10:8.06; #11:8.11; #12:9.42; #13:9.00), reversing the effects of DPDPE ([D-Pen(2,5)]enkephalin). In β-arrestin assays, compared with fentanyl (with response at maximum concentration (RMC):13.62), all compounds showed reduced ability to activate β-arrestin (#9 RMC:1.58; #10:2.72; #11:2.40; #12:1.29; #13:1.58). Compared with fentanyl, the intrinsic activity was: #9:0.12; #10:0.20; #11:0.18; #12:0.09 and #13:0.12.

CONCLUSIONS

The addition of a linker between fentanyl and Dmt-Tic did not alter the ability to bind to MOP and DOP, however a substantial loss in MOP functional activity was apparent. This highlights the difficulty in multifunctional opioid development.

Place of care: from referral to specialist palliative care until death

BACKGROUND

While there are many poorly standardised studies focusing on place of death, there are limited data on place(s) of care during the final stages of disease.

AIM

This study aims to identify where patients are cared for in the interval from referral to specialist palliative care until death.

METHODS

All patients who died while under the care of a specialist palliative care service over a 6-month period were considered.

RESULTS

Of the 507 patients included, 255 (50.3%) were men and 428 (84.4%) had a malignant diagnosis. The mean referral-to-death interval was 70 days (SD 113, Range 1-838). The majority (n=281, 55.4%) received care in a single care setting-hospital (28.4%), home (21.5%), nursing home/community hospital (4.1%), hospice (1.4%)-and had a shorter mean referral-to-death interval. Most patients with more than one care setting spent three-quarters of their time in their normal place of residence. A total of 199 (39.3%) died in hospital, 131 (25.8%) in hospice, 131 (25.8%) at home (25.8%) and 46 (9.1%) in a nursing home/community hospital. Patients referred by a general practitioner (n=80 patients, 15.8%) were more likely to be cared for at home (p<0.001), and die at home (p<0.001).

CONCLUSIONS

A significant number of patients received specialist palliative care across multiple care settings. Late referral is associated with a single domain of care. General practitioner involvement supports patient care and death at home. Place of care and ease of transfer between care settings may be better indicators of the quality of care we provide.

Bereaved family member perceptions of patient-focused family-centred care during the last 30 days of life using a mortality follow-back survey: does location matter?

BACKGROUND

Improving end-of-life care is an important international issue. Recently Nova Scotia researchers conducted a mortality follow-back survey to provide a population-based description of care provided to adults during their last 30 days of life as perceived by knowledgeable bereaved family members. Here we describe the relationship between the location where the decedent received the majority of care during their last 30 days and the informant's perception of the extent of unmet need, as defined by multiple domains of patient-focused, family-centred care.

METHOD

Death certificate identified informants (next-of-kin) of eligible adults who died between June 2009 and May 2011, in Nova Scotia, Canada were invited to participate in a telephone interview based on the After-Death Bereaved Family Member Interview. Whether or not the informant expressed unmet need or concerns for six patient-focused, family-centred care domains were assessed in relation to the location where the majority of care occurred during the decedent's last 30 days.

RESULTS

1358 informants took part (25% response rate). Results of 1316 eligible interviews indicated home (39%) was the most common location of care, followed by long-term care (29%), hospital (23%) and hospital-based palliative-care units (9%). Unmet need ranged from 5.6% for dyspnea help to 66% for the emotional and spiritual needs of the family. Although the mean score for overall satisfaction was high (mean = 8.7 in 1-10 scale; SD 1.8), 57% were not completely satisfied. Compared to home, adjusted results indicated greater dissatisfaction with overall care and greater communication concerns in the hospital. Greater unmet need occurred at home for dyspnea. Less overall dissatisfaction and unmet need were expressed about care provided in long-term care facilities and hospital-based palliative-care units.

CONCLUSION

Bereaved informants were generally highly satisfied with the decedent's care during their last 30 days but variations were evident. Overall, no one location stood out as exceptionally different in terms of perceived unmet need within each of the patient-focused, family-centred care domains. Communication in various forms and family emotional and spiritual support were consistently viewed as lacking in all locations and identified as targeted areas for impacting quality care at end of life.

Home-based palliative care: a systematic literature review of the self-reported unmet needs of patients and carers

BACKGROUND

There have been many studies on the unmet needs of palliative care patients and carers from the perspective of bereaved caregivers. However, the unmet needs of palliative care patients and carers from the perspective of current patients and their carers have received little research attention.

AIM

As home-based services have become one of the main delivery models of palliative care, the aim of this review was to describe, evaluate and summarise the literature on the unmet needs of palliative home care patients and carers.

DESIGN

The systematic review of qualitative and quantitative studies was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

DATA SOURCES

PubMed, CINAHL, Embase, MEDLINE, PsycINFO, AMED and CareSearch were searched to find empirical studies on the self-reported unmet needs of palliative home care patients and carers.

RESULTS

Nine qualitative studies, three quantitative studies and three mixed-design studies were identified. The most frequently reported unmet need was effective communication with health-care professionals, the lack of which negatively impacted on the care received by patients and carers. Physical care needs were met, which indicates that the examined palliative home care services were delivering satisfactory care in this domain, but lacking in other areas.

CONCLUSIONS

The focus therefore should be on improving other aspects of patient care, including communication by health professionals to prevent or reduce suffering in areas such as psychosocial domains. Valid and reliable quantitative measures of unmet needs in palliative care are needed to examine this area more rigorously.

Prediction of long-term mortality by preoperative health-related quality-of-life in elderly onco-surgical patients

Objective

Aim of this study was to evaluate the association between preoperative health-related quality of life (HRQoL) and mortality in a cohort of elderly patients (>65 years) with gastrointestinal, gynecological and genitourinary carcinomas.

Design

Prospective cohort pilot study.

Setting

Tertiary university hospital in Germany.

Patients

Between June 2008 and July 2010 and after ethical committee approval and written informed consent, 126 patients scheduled for onco-surgery were included. Prior to surgery as well as 3 and 12 months postoperatively all participants completed the EORTC-QLQ-C30 questionnaire (measuring self-reported health-related quality of life). Additionally, demographic and clinical data including the Mini Mental State Examination (MMSE) were collected. Surgery and anesthesia were conducted according to the standard operating procedures. Primary endpoint was the cumulative mortality rate over 12 months after one year. Changes in Quality of life were considered as secondary outcome.

Results

Mortality after one year was 28%. In univariable and multivariable logistic regression analysis baseline HRQoL self-reported cognitive function (OR per point: 0.98; CI 95% 0.96–0.99; p = 0.024) and higher symptom burden for appetite loss (per point: OR 1.02; CI 95% 1.00–1.03; p = 0.014) were predictive for long-term mortality. Additionally the MMSE as an objective measure of cognitive impairment (per point: OR 0.69; CI 95% 0.51–0.96; p = 0.026) as well as severity of surgery (OR 0.31; CI 95% 0.11–0.93; p = 0.036) were predictive for long-term mortality. Global health status 12 months after surgery was comparable to the baseline levels in survivors despite moderate impairments in other domains.

Conclusion

This study showed that objective and self-reported cognitive functioning together with appetite loss were prognostic for mortality in elderly cancer patients. In addition, impaired cognitive dysfunction and severity of surgery were predictive for one-year mortality whereas in this selected population scheduled for surgery age, gender, cancer site and metastases were not.

The Conversations About Cancer (CAC) project: assessing feasibility and audience impacts from viewing The Cancer Play

Basic communication research has identified a major social problem: communicating about cancer from diagnosis through death of a loved one. Over the past decade, an award-winning investigation into how family members talk through cancer on the telephone, based on a corpus of 61 phone calls over a period of 13 months, has been transformed into a theatrical production entitled The Cancer Play. All dialogue in the play is drawn from naturally occurring (transcribed) interactions between family members as they navigate their way through the trials, tribulations, hopes, and triumphs of a cancer journey. This dramatic performance explicitly acknowledges the power of the arts as an exceptional learning tool for extending empirical research, exploring ordinary family life, and exposing the often taken-for-granted conceptions of health and illness. In this study, a Phase I STTR project funded by the National Cancer Institute (NCI), we assess the feasibility of educating and impacting cancer patients, family members, and medical professionals who viewed the play as a live performance and through DVD screenings. Pre- and postperformance questionnaires were administered to solicit audience feedback. Pre-post change scores demonstrate overwhelming and positive impacts for changing opinions about the perceived importance, and attributed significance, of family communication in the midst of cancer. Paired-sample t-tests were conducted on five factor-analyzed indices/indicators-two indices of opinions about cancer and family communication, two indices measuring the importance of key communication activities, and the self-efficacy indicator-and all factors improved significantly (<.001). Informal talkback sessions were also held following the viewings, and selected audience members participated in focus groups. Talkback and focus-group sessions generated equally strong, support responses. Implications of the Phase I study are being applied in Phase II, a currently funded effort to disseminate the play nationally and to more rigorously test its impact on diverse audiences. Future directions for advancing research, education, and training across diverse academic and health care professions are discussed.

The development of a 7-day community specialist palliative care service

The author worked as a clinical nurse specialist (CNS) in community palliative care in the Central Lancashire area of England when the CNS service was extended to a 9am-to-5pm 7-day service. A project group was set up to canvas some of the key stakeholders for their views on the extension of the service. The group undertook a literature search, a telephone survey of services in other areas that were providing this level of service, and interviews to ascertain the views of district nurses in the locality of the proposed service extension. The extension of service has long been advocated and was one of the key recommendations in the UK Department of Health's peer-review process. Such an extension was implemented following the research phase and was then evaluated by the project lead and the community services manager. The extension was found to be effective in the ongoing monitoring and support of patients. Anecdotally, the CNS team also felt it had been proactive in preventing unnecessary hospital admissions, although this specific aspect is difficult to quantify. This article looks at how the service was developed, how it has evolved over time, and how it works today. Consideration is also given to benefits and limitations.

Informal caregiving for cancer patients

According to the recent worldwide estimation by the GLOBOCAN project, in total, 12.7 million new cancer cases and 7.6 million cancer deaths occurred in 2008. The worldwide number of cancer survivors within 5 years of diagnosis has been estimated at be almost 28.8 million. Informal caregivers, such as family members and close friends, provide essential support to cancer patients. The authors of this report provide an overview of issues in the study of informal caregivers for cancer patients and long-term survivors in the United States and Europe, characterizing the caregivers commonly studied; the resources currently available to them; and their unmet needs, their psychosocial outcomes, and the psychosocial interventions tailored to their special circumstances. A broad overview of the state of research and knowledge, both in Europe and the United States, and observations on the directions for future research are provided.

Psychosocial consequences of cancer cachexia: the development of an item bank

CONTEXT

Cancer cachexia syndrome (CCS) is often accompanied by psychosocial consequences (PSC). To alleviate PSC, a systematic assessment method is required. Currently, few assessment tools are available (e.g., Functional Assessment of Anorexia/Cachexia Therapy). There is no systematic assessment tool that captures the PSC of CCS.

OBJECTIVES

To develop a pilot item bank to assess the PSC of CCS.

METHODS

A total of 132 questions, generated from patient answers in a previous study, were reduced to 121 items by content analysis and evaluation by multidisciplinary experts (doctor, nutritionists, and nurses). In our two-step, cross-sectional study, patients, judged by staff to have PSC of CCS, were included, and the questions were randomly allocated to the patients. Questions were evaluated for understandability and triggering emotions, and patients were asked to provide a response using a four-point Likert scale. Subsequently, problematic questions were revised, reformulated, and retested.

RESULTS

A total of 20 patients with a variety of tumor types participated. Of the 121 questions, 31 had to be reformulated after Step 1 and were retested in Step 2, after which seven were again evaluated as not being perfectly comprehensible. In Step 1, 22 questions were found to trigger emotions, but no item required remodeling. Item performance using the Likert scale revealed no consistent floor or ceiling effects. Our final pilot question bank comprised 117 questions.

CONCLUSION

The final item bank contains questions that are understood and accepted by the patients. This item bank now needs to be developed into a measurement tool that groups items into domains and can be used in future research studies.

Pain and hospice care in nursing home residents with dementia and terminal cancer

AIM

One condition associated with severe end-of-life pain that can lead to a poor quality of death is cancer. Cancer pain in people with dementia is of particular concern because of communication problems that occur with worsening disease. The aim of the current pilot study was to examine the association between hospice enrolment, dementia severity and pain among nursing home residents who died from advanced cancer.

METHODS

Between-groups cross-sectional chart audits of 55 nursing home residents with dementia who died from cancer were carried out.

RESULTS

A total of 45% of residents were in hospice at the end-of-life. Residents in hospice were more likely to receive an opioid (80% vs 43%, P = 0.005); but less likely to show severe cognitive impairment (20% vs 50%, P = 0.050). Enrolment in hospice was associated with an increased likelihood of receiving an opioid after controlling for level of cognitive impairment (OR = 3.9, 95% CI = 1.1-14.0, P = 0.037). Lower levels of cognitive functioning were associated with a decreased likelihood of receiving an opioid after controlling for enrolment in hospice (OR = 0.3, 95% CI = 0.1-0.8, P = 0.030). Notably, 40% of nursing home residents with dementia who died from cancer did not receive any opioid during this time.

CONCLUSIONS

Preliminary results suggest that hospice enrolment might be influenced by the facility or region of this particular country. Hospice enrolment predicts more opioid pain treatment in residents with dementia and terminal cancer; however, no resident with very severe dementia and terminal cancer was placed in hospice care. Severely cognitively impaired nursing home residents requiring opioids are at great risk of suffering from untreated advanced cancer pain. New methods are urgently required to improve end-of-life palliative care for nursing home residents with terminal cancer and severe dementia.

Challenges and strategies in the administration of a population based mortality follow-back survey design

Population-based mortality follow-back survey designs have been used to collect information concerning end-of-life care from bereaved family members in several countries. In Canada, this design was recently employed to gather population-based information about the end-of-life care experience among adults in Nova Scotia as perceived by the decedent's family. In this article we describe challenges that emerged during the implementation of the study design and discuss resolutions strategies to help overcome them. Challenges encountered included the inability to directly contact potential participants, difficulties ascertaining eligibility, mailing strategy complications and the overall effect of these issues on response rate and subsequent sample size. Although not all challenges were amenable to resolution, strategies implemented proved beneficial to the overall process and resulted in surpassing the targeted sample size. The inability to directly contact potential participants is an increasing reality and limitations associated with this process best acknowledged during study development. Future studies should also consider addressing participant concerns pertaining to their eligibility and use of a more cost effective mailing strategy.

A systematic review of the prevalence of signs of impending death and symptoms in the last 2 weeks of life

To optimally manage patient care, knowledge of the prevalence of signs of impending death and common symptoms in the last days is needed. Two reviewers independently conducted searches of PubMed, CINAHL, PsychINFO and the Web of Knowledge from January, 1996 to May, 2012. No limits to publication language or patient diagnosis were imposed. Peer reviewed studies of adults that included contemporaneous documentation of signs and symptoms were included. Articles were excluded if they assessed symptoms by proxy or did not provide information on prevalence. Reviewers independently extracted data. Twelve articles, representing 2416 patients, in multiple settings were analyzed. Of the 43 unique symptoms, those with the highest prevalence were: dyspnea (56.7%), pain (52.4%), respiratory secretions/death rattle (51.4%), and confusion (50.1%). Overall prevalence may be useful in anticipating symptoms in the final days and in preparing families for signs of impending death.
