Palliative care program effectiveness research: developing rigor in sampling design, conduct, and reporting

A Mixed Methods Evaluation of a Pilot Multidisciplinary Breathlessness Support Service

Breathlessness support services have demonstrated benefits for breathlessness mastery, quality of life and psychosocial outcomes for people living with breathlessness. However, these services have predominantly been implemented in hospital and home care contexts. This study aims to evaluate the adaptation and implementation of a hospice-based outpatient Multidisciplinary Breathlessness Support Service (MBSS) in Ireland. A sequential explanatory mixed methods design guided this study. People with chronic breathlessness participated in longitudinal questionnaires (n = 10), medical record audit (n = 14) and a post-discharge interview (n = 8). Caregivers (n = 1) and healthcare professionals involved in referral to (n = 2) and delivery of (n = 3) the MBSS participated in a cross-sectional interview. Quantitative and qualitative data were integrated deductively via the pillar integration process, guided by the RE-AIM framework. Integration of mixed methods data enhanced understanding of factors influencing the reach, adoption, implementation and maintenance of the MBSS, and the potential outcomes that were most meaningful for service users. Potential threats to the sustainability of the MBSS related to potential preconceptions of hospice care, the lack of standardized discharge pathways from the service and access to primary care services to sustain pharmacological interventions. This study suggests that an adapted multidisciplinary breathlessness support intervention is feasible and acceptable in a hospice context. However, to ensure optimal reach and maintenance of the intervention, activities are required to ensure that misconceptions about the setting do not influence willingness to accept referral to MBSS services and integration of services is needed to enable consistency in referral and discharge processes.

Developing and Field Testing BOLSTER: A Nurse-Led Care Management Intervention to Support Patients and Caregivers following Hospitalization for Gynecologic Cancer-Associated Peritoneal Carcinomatosis

Introduction: Peritoneal carcinomatosis (PC) afflicts women with advanced gynecologic cancers. Patients with PC often require ostomies, gastric tubes, or catheters to palliate symptoms, yet patients and caregivers report feeling unprepared to manage these devices. The purpose of this study was to develop and field test the Building Out Lifelines for Safety, Trust, Empowerment, and Renewal (BOLSTER) intervention to support patients and their caregivers after hospitalization for PC. Materials and Methods: We adapted components of the Standard Nursing Intervention Protocol with stakeholders and topical experts. We developed educational content; built a smartphone application to assess patients' symptoms; and assessed preliminary feasibility and acceptability in two single-arm prepilot studies. Eligible participants were English-speaking adults hospitalized for gynecologic cancer-associated PC and their caregivers. Feasibility criteria were a ≥50% consent-to-approach ratio and ≥80% outcome measure completion. The acceptability criterion was ≥70% of participants recommending BOLSTER. Results: During the first prepilot, BOLSTER was a 10-week intervention. While 7/8 (87.5%) approached patients consented, we experienced high attrition to hospice. Less than half of patients (3/7) and caregivers (3/7) completed outcome measures. For the second prepilot, BOLSTER was a four-week intervention. All (7/7) approached patients consented. Two withdrew before participating in any study activity because they were "too overwhelmed." We excluded data from one caregiver who completed baseline measures with the patient's assistance. All remaining patients (5/5) and caregivers (4/4) completed outcome measures and recommended BOLSTER. Conclusion: BOLSTER is a technology-enhanced, nurse-led intervention that is feasible and acceptable to patients with gynecologic cancer-associated PC and their caregivers.

What are the personal last wishes of people with a life-limiting illness? Findings from a longitudinal observational study in specialist palliative care

Background

Personal last wishes of people facing a life-limiting illness may change closer to death and may vary across different forms of specialist palliative care (SPC).

Aims

To explore the presence and common themes of last wishes over time and according to the SPC settings (inpatient vs. home-based SPC), and to identify factors associated to having a last wish.

Methods

Patients enrolled in a longitudinal study completed questionnaires at the onset (baseline, t₀) and within the first 6 weeks (follow-up, t₁) of SPC including an open-ended question on their personal last wishes. Last wishes were content analyzed, and all  wishes were coded for presence or absence of each of the identified themes. Changes of last wishes (t₀-t₁) were analyzed by a McNemar test. The chi-square-test was used to compare the two SPC settings. Predictors for the presence of a last wish were identified by logistic regression analysis.

Results

Three hundred sixty-one patients (mean age, 69.5 years; 49% female) answered at t₀, and 130 at t₁. In cross-sectional analyses, the presence of last wishes was higher at t₀ (67%) than at t₁ (59%). Comparisons revealed a higher presence of last wishes among inpatients than those in home-based SPC at t₀ (78% vs. 62%; p = .002), but not at t₁. Inpatient SPC (OR = 1.987, p = .011) and greater physical symptom burden over the past week (OR = 1.168, p < .001) predicted presence of a last wish at t₀. Common themes of last wishes were Travel, Activities, Regaining health, Quality of life, Being with family and friends, Dying comfortably, Turn back time, and Taking care of final matters. The most frequent theme was Travel, at both t₀ (31%) and t₁ (39%). Themes did not differ between SPC settings, neither at t₀ nor at t₁. Longitudinal analyses (t₀-t₁) showed no significant intra-personal changes in the presence or any themes of last wishes over time.

Conclusions

In this late phase of their illness, many patients voiced last wishes. Our study suggests working with such wishes as a framework for person-centered care. Comparisons of SPC settings indicate that individualized approaches to patients’ last wishes, rather than setting-specific approaches, may be important.

End-of-life and hospice care for neurologic illness

Systems for end of life care around the world vary in availability, structure, and funding. When available, most end of life care is in the hospice model with an interdisciplinary team approach to care of people who are expected to die within months and whose primary goal is to maximize quality of life. Symptom management near the end of life is guided by prognosis and individual priorities. People dying with neurologic disease are likely to have impaired communication or mobility that adds to the complexity of prognostication and symptom management. Neurologic specialists have important roles to play in end of life care due to their unique understanding of disease prognosis as well as end of life symptom burden and management. Neurologic specialists need to become strong advocates for the importance of end of life care by being actively involved in the hospice movement and by addressing current disparities in access to care.

Association between attendance at a specialist palliative care day unit and improvement in patient symptoms and quality of life

BACKGROUND

Specialist palliative day care is an area of palliative care which has a notable scarcity of research. Evidence is needed on the role of palliative day care to improve patients' quality of life and symptom management, while recognising the different patient cohorts that use the service.

AIM

To determine the symptoms and quality of life of the patient cohort that are affected by the completion of a full therapeutic cycle (8 to 9 weeks) at a specialist palliative care day unit (SPCDU).

METHOD

A retrospective cohort study was carried out from January 2016 to December 2017. Patient related outcome measures (PROMs) were collected as part of routine clinical paperwork at admission and discharge, and these were used to determine symptoms and quality of life pre-attendance and on completion of an 8 to 9 week therapeutic cycle at the SPCDU.

RESULTS

Descriptive analysis demonstrated improvement across the many symptoms that were analysed. Quality of life analysis also established improvement. Statistically significant difference was achieved in several areas. Total physical symptoms (p value=.009) confirmed the positive impact attendance at SPCDU has on physical symptoms. Specific symptoms which displayed a statistically significant difference included: poor appetite (p value=.002), weakness (p value=.03) and the anxiety felt by family/friends (p value=.029). The quality of a patient's life also displayed statistically significant difference (p value=.000).

CONCLUSION

This study demonstrates that attendance at a SPCDU may positively impact a patients' symptoms and quality of life. A more uniform national approach to specialist palliative day care delivery, alongside multi-setting research, may further bolster the image of palliative day care. This will improve referrals to and occupancy of SPDCUs and benefit the palliative patient in the community.

A nurse-led self-management support intervention for patients and informal caregivers facing incurable cancer: A feasibility study from the perspective of nurses

PURPOSE

Investigation of the feasibility of recruitment through nurses of patients with incurable cancer, and the feasibility (adoption, usage) and nurses' evaluation of a nurse-led self-management support intervention, integrated in continuity home visits and based on the 5 A's Behavior Change Model.

METHOD

Questionnaire, registrations, evaluation forms, and interviews.

RESULTS

Recruitment was complicated; many patients were ineligible for participation, nurses appeared protective of their patients (gatekeeping), and recruitment during the first continuity home visit appeared to be a barrier as a lot of other issues had to be discussed. The adoption rate was 81%, meaning that 18 out of 22 nurses recruited were willing to use the intervention. The usage rate at the nurse level was 56%, meaning that 10 nurses applied the intervention in full (having applied all five A's) in at least one patient. Nurses used the intervention in full in 21 out of the 36 patients included, implying a usage rate at the patient level of 58%. Nurses' mean general satisfaction score for the intervention was 7.57 (range 0-10). Nurse were especially positive about the 5 A's model, and considered the continuity home visits to be an appropriate setting for the intervention.

CONCLUSIONS

Timing of recruitment and gatekeeping complicated recruitment of patients through nurses. Although nurses were positive about the intervention, nurses often did not fully apply the intervention. To improve its usage, it is suggested that nurses should first be trained in using the 5 A's model.

The Perceived Facilitators and Challenges of Translating a Lung Cancer Palliative Care Intervention Into Community-Based Settings

Despite significant progress in implementing palliative care interventions for patients with cancer, few intervention studies seek health care clinicians' input before implementation of these into the community. The purpose of this study was to explore palliative care and oncology clinicians' perspectives on the perceived facilitators and challenges in meeting the quality-of-life needs of patients with lung cancer and family caregivers in community-based settings. The Reach Effectiveness Adoption Implementation Maintenance model for implementation research was used as a framework. This was a multisite qualitative study using focus group and key informant interviews. Nineteen clinicians addressed useful practices and challenges in the following areas: (a) early palliative care, (b) interdisciplinary care planning, (c) symptom management, (d) addressing psychological and social needs, and (e) providing culturally respectful care, including spiritual care. In preparation for the intervention, specific education needs and organizational challenges were revealed. Challenges included timing and staffing constraints, the need for clinician education on palliative care services to increase organizational buy-in, and education in providing spiritual support for patients and family caregivers. This research allowed investigators to understand perceptions of clinicians as they prepared to integrate palliative care in their settings. Hospice and palliative care nurses can be instrumental in implementing palliative care into community practice.

Managing uncertain recovery for patients nearing the end of life in hospital: a mixed-methods feasibility cluster randomised controlled trial of the AMBER care bundle

BACKGROUND

The AMBER (Assessment, Management, Best Practice, Engagement, Recovery Uncertain) care bundle is a complex intervention used in UK hospitals to support patients with uncertain recovery. However, it has yet to be evaluated in a randomised controlled trial (RCT) to identify potential benefits or harms. The aim of this trial was to investigate the feasibility of a cluster RCT of the AMBER care bundle.

METHODS

This is a prospective mixed-methods feasibility cluster RCT. Quantitative data collected from patients (or proxies if patients lack capacity) were used (i) to examine recruitment, retention and follow-up rates; (ii) to test data collection tools for the trial and determine their optimum timing; (iii) to test methods to identify the use of financial resources; and (iv) to explore the acceptability of study procedures for health professionals and patients. Descriptive statistical analyses and thematic analysis used the framework approach.

RESULTS

In total, 894 patients were screened, of whom 220 were eligible and 19 of those eligible (8.6%) declined to participate. Recruitment to the control arm was challenging. Of the 728 patients screened for that arm, 647 (88.9%) were excluded. Overall, 65 patients were recruited (81.3% of the recruitment target of 80). Overall, many were elderly (≥80 years, 46.2%, n = 30, mean = 77.8 years, standard deviation [SD] = 12.3 years). Over half (53.8%) had a non-cancer diagnosis, with a mean of 2.3 co-morbidities; 24.6% patients (n = 16) died during their hospital stay and 35.4% (n = 23) within 100 days of discharge. In both trial arms, baseline IPOS subscale scores identified moderate patient anxiety (control: mean 13.3, SD 4.8; intervention: mean 13.3, SD 5.1), and howRwe identified a good care experience (control: mean 13.1, SD 2.5; intervention: mean 11.5, SD 2.1). Collecting quantitative service use and quality of life data was feasible. No patient participants regarded study involvement negatively. Focus groups with health professionals identified concerns regarding (i) the subjectivity of the intervention's eligibility criteria, (ii) the need to prognosticate to identify potential patients and (iii) consent procedures and the length of the questionnaire.

CONCLUSIONS

A full trial of the AMBER care bundle is technically feasible but impractical due to fundamental issues in operationalising the intervention's eligibility criteria, which prevents optimal recruitment. Since this complex intervention continues to be used in clinical care and advocated in policy, alternative research approaches must be considered and tested.

Using the 'Social Marketing Mix Framework' to explore recruitment barriers and facilitators in palliative care randomised controlled trials? A narrative synthesis review

BACKGROUND

Effective recruitment to randomised controlled trials is critically important for a robust, trustworthy evidence base in palliative care. Many trials fail to achieve recruitment targets, but the reasons for this are poorly understood. Understanding barriers and facilitators is a critical step in designing optimal recruitment strategies.

AIM

To identify, explore and synthesise knowledge about recruitment barriers and facilitators in palliative care trials using the '6 Ps' of the 'Social Marketing Mix Framework'.

DESIGN

A systematic review with narrative synthesis.

DATA SOURCES

Medline, CINAHL, PsycINFO and Embase databases (from January 1990 to early October 2016) were searched. Papers included the following: interventional and qualitative studies addressing recruitment, palliative care randomised controlled trial papers or reports containing narrative observations about the barriers, facilitators or strategies to increase recruitment.

RESULTS

A total of 48 papers met the inclusion criteria. Uninterested participants (Product), burden of illness (Price) and 'identifying eligible participants' were barriers. Careful messaging and the use of scripts/role play (Promotion) were recommended. The need for intensive resources and gatekeeping by professionals were barriers while having research staff on-site and lead clinician support (Working with Partners) was advocated. Most evidence is based on researchers' own reports of experiences of recruiting to trials rather than independent evaluation.

CONCLUSION

The 'Social Marketing Mix Framework' can help guide researchers when planning and implementing their recruitment strategy but suggested strategies need to be tested within embedded clinical trials. The findings of this review are applicable to all palliative care research and not just randomised controlled trials.

Recruiting and Retaining Patient-Caregiver-Nurse Triads for Qualitative Hospice Cancer Pain Research

BACKGROUND

Qualitative pain research for hospice patients with cancer and their caregivers involves recruiting and retaining participants with multiple vulnerabilities and ethical and logistical challenges. These have been reported for studies of individuals or dyads. However, there are no reports of the related challenges and outcomes where the sampled population was a hospice triad.

OBJECTIVES

Qualitative research about pain management for home hospice patients with cancer contributes rich descriptive data and such studies are critical to improving cancer pain outcomes. We describe the ethical and pragmatic challenges we faced in a study of the hospice caring triad, operationalized as the patient, family caregiver, and nurse; how our study design anticipated them; and related outcomes.

RESULTS

We found that having an established relationship with the hospice agency at which we recruited participants, clearly identifying potential participants at the onset of hospice care, practice using a recruitment script, patient recruitment of caregivers, establishing rapport, and participants determining when interviews should end helped us recruit and retain our sample. We were unable to accrue our anticipated triad sample, partially because of nurse gatekeeping and the condition at admission of patient participants who enrolled but had physical decline or died prior to written consent.

CONCLUSIONS

Although researchers will always face challenges to enrolling individuals and groups in cancer pain studies, with careful study design, recruitment, and retention planning and research team-participant engagement, it is possible to gather a robust corpus of qualitative data.

Palliative Care for Patients and Families With Parkinson's Disease

Parkinson's disease is the second most common neurodegenerative disease worldwide. There is widespread consensus that Parkinson patients, their carers, and clinicians involved in their care would benefit from a fully integrated, need-based provision of palliative care. However, the concept of palliative care in Parkinson's disease is still poorly defined and, consequently, poorly implemented into daily clinical practice. A particular challenge is the gradually progressive nature of Parkinson's disease-with insidiously increasing disability-making it challenging to clearly define the onset of palliative care needs for Parkinson patients. As people with Parkinson's disease are now living longer than in the past, future research needs to develop a more robust evidence-based approach to clarify the disease events associated with increased palliative care needs, and to examine these, prospectively, in an integrated palliative care service. The modern palliative care outlook, termed "simultaneous care,",is no longer restricted to the final stage of disease. It involves incorporating a continuity of care, effective management of the chronic-palliative interface, and a multidisciplinary network of professionals working both in the community and in specialized clinics, with active involvement of caregivers. Although promising, there is still a need to demonstrate the effectiveness of palliative care for patients with Parkinson's disease.

Clinical trials in palliative care: a systematic review of their methodological characteristics and of the quality of their reporting

Background

Over the past decades there has been a significant increase in the number of published clinical trials in palliative care. However, empirical evidence suggests that there are methodological problems in the design and conduct of studies, which raises questions about the validity and generalisability of the results and of the strength of the available evidence. We sought to evaluate the methodological characteristics and assess the quality of reporting of clinical trials in palliative care.

Methods

We performed a systematic review of published clinical trials assessing therapeutic interventions in palliative care. Trials were identified using MEDLINE (from its inception to February 2015). We assessed methodological characteristics and describe the quality of reporting using the Cochrane Risk of Bias tool.

Results

We retrieved 107 studies. The most common medical field studied was oncology, and 43.9% of trials evaluated pharmacological interventions. Symptom control and physical dimensions (e.g. intervention on pain, breathlessness, nausea) were the palliative care-specific issues most studied. We found under-reporting of key information in particular on random sequence generation, allocation concealment, and blinding.

Conclusions

While the number of clinical trials in palliative care has increased over time, methodological quality remains suboptimal. This compromises the quality of studies. Therefore, a greater effort is needed to enable the appropriate performance of future studies and increase the robustness of evidence-based medicine in this important field.

Exploring family relationships through associations of comfort, relatedness states, and life closure in hospice patients: A pilot study

OBJECTIVE

Research at the end of life tends to focus on the dying patient's symptoms, often overlooking issues associated with family interactions. However, many families struggle just to maintain or initiate these valuable connections. The purpose of our pilot study was to explore family relationships at the end of life and investigate associations among perceived comfort, relatedness states, and life closure.

METHOD

This descriptive study used a cross-sectional design, and a convenience sample (n = 30; 18 women; mean age = 71 years) was recruited from patients admitted to a large not-for-profit hospice in northeastern Ohio. In-person interviews using the Hospice Comfort Questionnaire, Relatedness States Visual Analog Scales, and the Life-Closure Scale provided data for analyses.

RESULTS

Family interactions that were not associated with the physical tasks of caregiving were related to life closure (r = 0.36, p = 0.001), and life closure and comfort were highly correlated (r = 0.69, p < 0.001). Participants residing in an inpatient setting had higher levels of involvement (t[18] = -2.07, p = 0.05) and comfort in relationships (t[28] = -2.06, p = 0.05) than those in the home setting.

SIGNIFICANCE OF RESULTS

This is the first known study investigating the associations among comfort, relatedness, and life closure at the end of life. The majority of participants had high levels of involvement and comfort in their relationships, and they preferred interactions that required minimal effort. Studies that focus on both patients' and family members' perceptions of relationships are needed as well as outcome studies that test simple interventions.

Oncologists' perspectives on concurrent palliative care in a National Cancer Institute-designated comprehensive cancer center

OBJECTIVE

The purpose of this study was to understand oncology clinicians' perspectives about the care of advanced cancer patients following the completion of the ENABLE II (Educate, Nurture, Advise, Before Life Ends) randomized clinical trial (RCT) of a concurrent oncology palliative care model.

METHOD

This was a qualitative interview study of 35 oncology clinicians about their approach to patients with advanced cancer and the effect of the ENABLE II RCT.

RESULTS

Oncologists believed that integrating palliative care at the time of an advanced cancer diagnosis enhanced patient care and complemented their practice. Self-assessment of their practice with advanced cancer patients comprised four themes: (1) treating the whole patient, (2) focusing on quality versus quantity of life, (3) “some patients just want to fight,” and (4) helping with transitions; timing is everything. Five themes comprised oncologists' views on the complementary role of palliative care: (1) “refer early and often,” (2) referral challenges: “Palliative” equals “hospice”; “Heme patients are different,” (3) palliative care as consultants or co-managers, (4) palliative care “shares the load,” and (5) ENABLE II facilitated palliative care integration.

SIGNIFICANCE OF RESULTS

Oncologists described the RCT as holistic and complementary, and as a significant factor in adopting concurrent care as a standard of care.

Health system characteristics of quality care delivery: a comparative case study examination of palliative care for cancer patients in four regions in Ontario, Canada

BACKGROUND

A number of palliative care delivery models have been proposed to address the structural and process gaps in this care. However, the specific elements required to form competent systems are often vaguely described.

AIM

The purpose of this study was to explore whether a set of modifiable health system factors could be identified that are associated with population palliative care outcomes, including less acute care use and more home deaths.

DESIGN

A comparative case study evaluation was conducted of 'palliative care' in four health regions in Ontario, Canada. Regions were selected as exemplars of high and low acute care utilization patterns, representing both urban and rural settings. A theory-based approach to data collection was taken using the System Competency Model, comprised of structural features known to be essential indicators of palliative care system performance. Key informants in each region completed study instruments. Data were summarized using qualitative techniques and an exploratory factor pattern analysis was completed.

RESULTS

43 participants (10+ from each region) were recruited, representing clinical and administrative perspectives. Pattern analysis revealed six factors that discriminated between regions: overall palliative care planning and needs assessment; a common chart; standardized patient assessments; 24/7 palliative care team access; advanced practice nursing presence; and designated roles for the provision of palliative care services.

CONCLUSIONS

The four palliative care regional 'systems' examined using our model were found to be in different stages of development. This research further informs health system planners on important features to incorporate into evolving palliative care systems.

Designing Research With Hospice and Palliative Care Populations

Research in palliative care and hospice populations is important for improving quality of care, quality of life, and provider understanding of individuals at the end of life. However, this research involves many potential challenges. This review seeks to inform and assist researchers targeting to design studies targeting hospice and palliative care patients by presenting a thorough review of the published literature. This review covers English-language articles published from 1990 through 2009 listed in the PsycInfo, Medline, or CINAHL research databases under relevant keywords. Articles on pediatric hospice were not included. Issues discussed include study design, informed consent, and recruitment for participants. Synthesized recommendations for researchers in these populations are presented.

Formal feasibility studies in palliative care: why they are important and how to conduct them

The concept of clinical trial feasibility is of great interest to the community of palliative care researchers, clinicians, and granting agencies. Significant allocation of resources is required in the form of funding, time, intellect, and motivation to carry out clinical research, and understandably, clinical investigators, institutions, and granting agencies are disappointed when funded trials are unsuccessfully conducted. We argue that for many trials conducted in palliative care, the feasibility of conducting the proposed trial should be formally explored before implementation. There is substantial information available within the literature on the topic of study feasibility but no singular guide on how one can pragmatically apply this advice in the palliative care setting. We suggest that a Formal Feasibility Study for palliative care trials should be commonly conducted before development of a larger pivotal trial, to prospectively identify barriers to research, develop strategies to address these barriers, and predict whether the larger study is feasible. If a Formal Feasibility Study is not required, elements of feasibility can be specifically tested before launching clinical trials. The purpose of this article is to offer a draft framework for the design and conduct of a Formal Feasibility Study that, if implemented, could concretely support successful completion of high-quality research in a timely fashion. Additionally, we hope to foster dialogue within the palliative care research community regarding the relevance of establishing feasibility before initiation of definitive trials in the palliative care population.

Exploring generalizability in a study of costs for community-based palliative care

CONTEXT

Palliative care researchers face challenges recruiting and retaining study subjects.

OBJECTIVES

This article investigates selection, study site, and participation biases to assess generalizability of a cost analysis of palliative care program (PCP) clients receiving care at home.

METHODS

Study subjects' sociodemographic, geographic, survival, disease, and treatment characteristics were compared for the same year and region with those of three populations. Comparison I was with nonstudy subjects enrolled in the PCP to assess selection bias. Comparison II was with adults who died of cancer to assess study site bias. Comparison III was with study-eligible persons who declined to participate in order to assess participation bias.

RESULTS

Comparison I: When compared with the other 1010 PCP clients, the 50 study subjects were on average 3.6 years younger (P=0.03), enrolled 70 days longer in the PCP (P<0.001), lived 6.7 km closer to the PCP (P<0.0001), and were more likely to have cancer (96.0% vs. 86.4%, P=0.05). Comparison II: Compared with all cancer decedents, the 45 study subjects who died of cancer were on average 7.0 years younger (P<0.001), lived 2.7 km closer to the PCP (P<0.001), and were more likely to have had radiotherapy (62.2% vs. 33.8%, P<0.0001) and medical oncology (28.9% vs. 14.8%, P=0.01) consultations. Comparison III: The 50 study subjects lived on average 42 days longer after their diagnosis (P=0.03) and 2.6 km closer to the PCP (P=0.01) than the 110 eligible persons who declined to participate.

CONCLUSION

If the study findings are applied to populations that differ from the study subjects, inaccurate conclusions are possible.

Physical activity and palliative cancer care

Palliative care is an interdisciplinary and holistic approach aimed at alleviating suffering from physical, psychosocial, and spiritual issues in progressive, advanced disease. Progressive fatigue and anorexia-cachexia syndrome can contribute to loss of physical function in the palliative cancer patient, to the detriment of overall quality of life. Physical activity is one potential intervention, which may address these needs in the palliative cancer patient. There is preliminary evidence that at least some palliative cancer patients are willing and able to tolerate physical activity interventions, with some patients demonstrating improvement in select supportive care outcomes postintervention. Methodologically rigorous studies and consensus on common definitions are required to advance this area of research.

A proposed taxonomy of terms to guide the clinical trial recruitment process

CONTEXT

The successful conduct of clinical trials in palliative care is challenged by low accrual rates, high attrition of study patients during trials, difficulties managing comorbidity, and other factors. But what has been learned about improving the feasibility of palliative care research studies?

OBJECTIVE

To develop standard terms to describe patient accrual, and using these terms, describe an approach to allow investigators to predict trial feasibility.

METHODS

We proposed a standard language and definitions for specific elements of feasibility within clinical trial design and conduct. We then developed an approach to apply data generated from the use of these terms to allow researchers to predict feasibility at the design stage of a clinical trial's development.

RESULTS

We developed a taxonomy and then retrospectively applied the approach to four trials selected from our library of completed studies, to provide preliminary validity evidence. The approach includes a framework to help predict the number of patients needed to be assessed to achieve a study's accrual targets, as part of ongoing operational oversight to monitor the conduct and feasibility of a clinical trial.

CONCLUSION

Challenges to successful completion of palliative care trials are prevalent and serious. A taxonomy to characterize the eligible patient pool, and an approach by which feasibility is systematically investigated, hold the promise to enhance the effectiveness of scarce resources applied to palliative and end-of-life research.

A proposed systems approach to the evaluation of integrated palliative care

BACKGROUND

There is increasing global interest in regional palliative care networks (PCN) to integrate care, creating systems that are more cost-effective and responsive in multi-agency settings. Networks are particularly relevant where different professional skill sets are required to serve the broad spectrum of end-of-life needs. We propose a comprehensive framework for evaluating PCNs, focusing on the nature and extent of inter-professional collaboration, community readiness, and client-centred care.

METHODS

In the absence of an overarching structure for examining PCNs, a framework was developed based on previous models of health system evaluation, explicit theory, and the research literature relevant to PCN functioning. This research evidence was used to substantiate the choice of model factors.

RESULTS

The proposed framework takes a systems approach with system structure, process of care, and patient outcomes levels of consideration. Each factor represented makes an independent contribution to the description and assessment of the network.

CONCLUSIONS

Realizing palliative patients' needs for complex packages of treatment and social support, in a seamless, cost-effective manner, are major drivers of the impetus for network-integrated care. The framework proposed is a first step to guide evaluation to inform the development of appropriate strategies to further promote collaboration within the PCN and, ultimately, optimal palliative care that meets patients' needs and expectations.

Effects of a palliative care intervention on clinical outcomes in patients with advanced cancer: the Project ENABLE II randomized controlled trial

CONTEXT

There are few randomized controlled trials on the effectiveness of palliative care interventions to improve the care of patients with advanced cancer.

OBJECTIVE

To determine the effect of a nursing-led intervention on quality of life, symptom intensity, mood, and resource use in patients with advanced cancer.

DESIGN, SETTING, AND PARTICIPANTS

Randomized controlled trial conducted from November 2003 through May 2008 of 322 patients with advanced cancer in a rural, National Cancer Institute-designated comprehensive cancer center in New Hampshire and affiliated outreach clinics and a VA medical center in Vermont.

INTERVENTIONS

A multicomponent, psychoeducational intervention (Project ENABLE [Educate, Nurture, Advise, Before Life Ends]) conducted by advanced practice nurses consisting of 4 weekly educational sessions and monthly follow-up sessions until death or study completion (n = 161) vs usual care (n = 161).

MAIN OUTCOME MEASURES

Quality of life was measured by the Functional Assessment of Chronic Illness Therapy for Palliative Care (score range, 0-184). Symptom intensity was measured by the Edmonton Symptom Assessment Scale (score range, 0-900). Mood was measured by the Center for Epidemiological Studies Depression Scale (range, 0-60). These measures were assessed at baseline, 1 month, and every 3 months until death or study completion. Intensity of service was measured as the number of days in the hospital and in the intensive care unit (ICU) and the number of emergency department visits recorded in the electronic medical record.

RESULTS

A total of 322 participants with cancer of the gastrointestinal tract (41%; 67 in the usual care group vs 66 in the intervention group), lung (36%; 58 vs 59), genitourinary tract (12%; 20 vs 19), and breast (10%; 16 vs 17) were randomized. The estimated treatment effects (intervention minus usual care) for all participants were a mean (SE) of 4.6 (2) for quality of life (P = .02), -27.8 (15) for symptom intensity (P = .06), and -1.8 (0.81) for depressed mood (P = .02). The estimated treatment effects in participants who died during the study were a mean (SE) of 8.6 (3.6) for quality of life (P = .02), -24.2 (20.5) for symptom intensity (P = .24), and -2.7 (1.2) for depressed mood (P = .03). Intensity of service did not differ between the 2 groups.

CONCLUSION

Compared with participants receiving usual oncology care, those receiving a nurse-led, palliative care-focused intervention addressing physical, psychosocial, and care coordination provided concurrently with oncology care had higher scores for quality of life and mood, but did not have improvements in symptom intensity scores or reduced days in the hospital or ICU or emergency department visits.

Researching breathlessness in palliative care: consensus statement of the National Cancer Research Institute Palliative Care Breathlessness Subgroup

Breathlessness is common in advanced disease and can have a devastating impact on patients and carers. Research on the management of breathlessness is challenging. There are relatively few studies, and many studies are limited by inadequate power or design. This paper represents a consensus statement of the National Cancer Research Institute Palliative Care Breathlessness Subgroup. The aims of this paper are to facilitate the design of adequately powered multi-centre interventional studies in breathlessness, to suggest a standardised, rational approach to breathlessness research and to aid future 'between study' comparisons. Discussion of the physiology of breathlessness is included.

A framework for generalizability in palliative care

Palliative medicine has only recently joined the ranks of evidence-based medical subspecialties. Palliative medicine is a rapidly evolving field, which is quickly moving to redress its historical paucity of high-quality research evidence. This burgeoning evidence base can help support the application of evidence-based principles in palliative and hospice clinical care and service delivery. New knowledge is generally taken into practice relatively slowly by established practitioners. At present, the translation of evidence into palliative and hospice care clinical practice lags behind emerging research evidence in palliative care at even greater rates for three critical reasons: 1) the application of research results to specific clinical subpopulations is complicated by the heterogeneity of palliative care study subpopulations and by the lack of a recognized schema for describing populations or services; 2) definitional issues in service provision are, at best, confusing; and 3) fundamental research concepts (e.g., external validity, effect size, generalizability, applicability) are difficult to apply meaningfully in palliative care. This article provides a suggested framework for classifying palliative care research subpopulations and the clinical subpopulations to which the research findings are being applied to improve the ability of clinicians, health planners, and funders to interpret and apply palliative care research in real-world settings. The framework has five domains: patients and caregivers; health professionals; service issues; health and social policy; and research.

The project ENABLE II randomized controlled trial to improve palliative care for rural patients with advanced cancer: baseline findings, methodological challenges, and solutions

OBJECTIVE

There is a paucity of randomized controlled trials (RCTs) to evaluate models of palliative care. Although interventions vary, all have faced a variety of methodological challenges including adequate recruitment, missing data, and contamination of the control group. We describe the ENABLE II intervention, methods, and sample baseline characteristics to increase intervention and methodological transparency, and to describe our solutions to selected methodological issues.

METHODS

Half of the participants recruited from our rural U.S. comprehensive cancer center and affiliated clinics were randomly assigned to a phone-based, nurse-led educational, care coordination palliative care intervention model. Intervention services were provided to half of the participants weekly for the first month and then monthly until death, including bereavement follow-up call to the caregiver. The other half of the participants were assigned to care as usual. Symptoms, quality of life, mood, and functional status were assessed every 3 months until death.

RESULTS

Baseline data of 279 participants were similar to normative samples. Solutions to methodological challenges of recruitment, missing data, and "usual care" control group contamination are described.

SIGNIFICANCE OF RESULTS

It is feasible to overcome many of the methodological challenges to conducting a rigorous palliative care RCT.

Reliability and validity of the Functional Assessment of Chronic Illness Therapy-Palliative care (FACIT-Pal) scale

The Functional Assessment of Chronic Illness Therapy (FACIT) system provides a general, multidimensional measure of health-related quality of life (FACT-G) that can be augmented with disease or symptom-specific subscales. The 19-item palliative care subscale of the FACIT system has undergone little psychometric evaluation to date. The aim of this paper is to report the internal consistency, factor structure, and construct validity of the instrument using the palliative care subscale (FACIT-Pal). Two hundred fifty-six persons with advanced cancer in a randomized trial testing a palliative care psychoeducational intervention completed the 46-item FACIT-Pal at baseline. Internal consistency was greater than 0.74 for all subscales and the total score. Seventeen of the 19 palliative care subscale items loaded onto the four-factor solution of the established core measure (FACT-G). As hypothesized, total scores were correlated with measures of symptom intensity (r=-0.73, P<0.001) and depression (r=-0.75, P<0.001). The FACIT-Pal was able to discriminate between participants who died within three months of completing the baseline and participants who lived for at least one year after completing the baseline assessment (t=-4.05, P<0.001). The functional well-being subscale discriminated between participants who had a Karnofsky performance score of 70 and below and participants with a Karnofsky performance score of 80 and above (t=3.40, P<0.001). The findings support the internal consistency reliability and validity of the FACIT-Pal as a measure of health-related quality of life for persons with advanced cancer.

Challenges in conducting end-of-life research in critical care

Critical care units present some unique challenges to the researcher, especially when the research topic of interest is related to end-of-life care. The purpose of this article is to address some of the methodological and practical issues related to conducting end-of-life research in the critical care setting. Recruitment barriers include gaining access to a clinical site, gaining access to patients, and prognostic uncertainty. Additional barriers include challenges related to informed consent, data collection, the research team, and ethical considerations. Strategies are described that can be used to guide researchers to conduct end-of-life research successfully in critical care.

Proxy perspectives regarding end-of-life care for persons with cancer

BACKGROUND

Each year, greater than a half million people die of cancer in the U.S. Despite progress in increasing access to palliative oncology services, end-of-life care still needs improvement. Measuring the quality of the end-of-life experience is difficult because of patient debility and reduced consciousness as death approaches. Family proxies have been proposed as valuable informants regarding the quality of end-of-life care. This article describes family proxy perspectives concerning care at the end of life in patients who died of advanced cancer.

METHODS

In the context of a novel outpatient palliative care demonstration project, 125 family proxy respondents completed a structured survey by telephone 3 months to 6 months after the patient's death from breast, lung, or gastrointestinal cancer. Four key quality of care indicators were measured: decision-making and physician communication, location of death, hospice involvement, and end-of-life symptoms.

RESULTS

Proxies reported that 78% to 81% of patients completed at least 1 form of advance directive and approximately half of them were helpful in guiding care. Communication with physicians regarding end-of-life treatment wishes occurred in 67% of cases, but only 57% of the patients actually made a plan with their physician to ensure that their wishes were followed. The majority of patients died in their location of choice, most often at home, and greater than half had hospice involvement for an average of 41.8 days before death. During the last week of life, the majority of patients experienced troublesome physical and emotional symptoms.

CONCLUSIONS

Measurement of proxy perspectives is feasible as an indicator of the quality of end-of-life care, and the results of the current study provide actionable data for areas of improvement in palliative oncology care.

A patient and carer survey in a community clinical nurse specialist service

The community clinical nurse specialist (CNS) team provides specialist palliative care to clients with cancer and non-malignant, life-limiting diseases in clients' homes, community hospitals, and residential and nursing homes. CNSs are based in health centres, community hospitals (geographically spread around the county) or at the local hospice. There has been no systematic review of patient and carer levels of satisfaction since the conception of the CNS service in 1984. Accredited as a nursing development unit (Flint and Wright, 2001) by Leeds University, the team has been encouraged to obtain service users' views. National guidelines in the UK (National Institute for Health and Clinical Excellence (NICE), 2004) also recommend that systems be put in place to enable clients to make their voices heard in a variety of ways. The principle aim was to identify the level of patient and carer satisfaction and to highlight aspects of care that warranted alteration or improvement. The CNS team were also keen to identify the aspects of their role most helpful to patients and carers, enabling CNSs to spend their time in a way that is most beneficial to clients.
