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

African American Recruitment in Early Heart Failure Palliative Care Trials: Outcomes and Comparison With the ENABLE CHF-PC Randomized Trial

BACKGROUND

Palliative care trial recruitment of African Americans (AAs) is a formidable research challenge.

OBJECTIVES

Examine AA clinical trial recruitment and enrollment in a palliative care randomized controlled trial (RCT) for heart failure (HF) patients and compare patient baseline characteristics to other HF palliative care RCTs.

METHODS

This is a descriptive analysis the ENABLE CHF-PC (Educate, Nurture, Advise, Before Life Ends: Comprehensive Heartcare for Patients and Caregivers) RCT using bivariate statistics to compare racial and patient characteristics and differences through recruitment stages. We then compared the baseline sample characteristics among three palliative HF trials.

RESULTS

Of 785 patients screened, 566 eligible patients with NYHA classification III-IV were approached; 461 were enrolled and 415 randomized (AA = 226). African Americans were more likely to consent than Caucasians (55%; P FDR = .001), were younger (62.7 + 8; P FDR = .03), had a lower ejection fraction (39.1 + 15.4; PFDR = .03), were more likely to be single (P FDR = .001), and lack an advanced directive (16.4%; P FDR < .001). AAs reported higher goal setting (3.3 + 1.3; P FDR = .007), care coordination (2.8 + 1.3; P FDR = .001) and used more "denial" coping strategies (0.8 + 1; P FDR = .001). Compared to two recent HF RCTs, the ENABLE CHF-PC sample had a higher proportion of AAs and higher baseline KCCQ clinical summary scores.

CONCLUSION

ENABLE CHF-PC has the highest reported recruitment rate and proportion of AAs in a palliative clinical trial to date. Community-based recruitment partnerships, recruiter training, ongoing communication with recruiters and clinician co-investigators, and recruiter racial concordance likely contributed to successful recruitment of AAs. These important insights provide guidance for design of future HF palliative RCTs.

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

CONTEXT

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSION

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

Mobile Application to Identify Cancer Treatment-Related Financial Assistance: Results of a Randomized Controlled Trial

PURPOSE

Insured patients with cancer face high treatment-related, out-of-pocket (OOP) costs and often cannot access financial assistance. We conducted a randomized, controlled trial of Bridge, a patient-facing app designed to identify eligible financial resources for patients. We hypothesized that patients using Bridge would experience greater OOP cost reduction than controls.

METHODS

We enrolled patients with cancer who had OOP expenses from January 2018 to March 2019. We randomly assigned patients 1:1 to intervention (Bridge) versus control (financial assistance educational websites). Primary and secondary outcomes were self-reported OOP costs and subjective financial distress 3 months postenrollment. In post hoc analyses, we analyzed application for and receipt of financial assistance at 3 months postenrollment. We used chi-square, Mann-Whitney tests, and logistic regression to compare study arms.

RESULTS

We enrolled 200 patients. The median age was 57 years (IQR, 47.0-63.0). Most patients had private insurance (71%), and the median household income was $62,000 in US dollars (USD) (IQR, $36,000-$100,000 [USD]). Substantial missing data precluded assessment of primary and secondary outcomes. In post hoc analyses, patients in the Bridge arm were more likely than controls to both apply for and receive financial assistance.

CONCLUSION

We were unable to test our primary outcome because of excessive missing follow-up survey data. In exploratory post hoc analyses, patients who received a financial assistance app were more likely to apply for and receive financial assistance. Ultimately, our study highlights challenges faced in identifying measurable outcomes and retaining participants in a randomized, controlled trial of a mobile app to alleviate financial toxicity.

Recruiting cancer survivors into research studies using online methods: a secondary analysis from an international cancer survivorship cohort study

Recruiting participants into cancer survivorship research remains a significant challenge. Few studies have tested and compared the relative use of non-clinical online recruitment methods, especially in samples of adult cancer survivors. This paper reports on the feasibility of recruiting a representative cohort of cancer survivors using online social media. Two hundred participants with cancer diagnosis within the past 12 months were recruited via social media (Facebook, Twitter and Reddit) into a longitudinal questionnaire study. Different methods of online recruitment proved to be more effective than others over time. Paid Facebook boosting, Reddit posts and Twitter advertisements placed by existing cancer charities proved most helpful in reaching our recruitment target (contributing 27%, 22% and 32%, respectively). Recruiting online achieved a more demographically and clinically representative sample for our study: our subject was younger, less heteronormative, including those with a range of clinical diagnoses, primary and recurrence illness, and patients who had both completed and were still receiving treatment. This was certainly not a quick method of sample recruitment but that could have been optimised by focussing only on the three most effective methods described earlier. While we found that online recruitment is significantly lower in cost than traditional recruitment methods, and can reduce some biases, there still remains the potential for some biases (e.g. excluding much older participants) and ethical/methodological issues (e.g. excluding those without access to Internet). We outline our recruitment strategy, retention rates and a cost breakdown in order to guide other researchers considering such methods for future research in cancer survivorship.

Therapeutic massage to enhance family caregivers' well-being in a rehabilitation hospital

BACKGROUND AND PURPOSE

A massage therapy program was implemented to address the psychological well-being of family caregivers to patients in a rehabilitation hospital. The impact of massage "dosage" on caregiver stress and psychological well-being was examined in this study. Participants' perspectives on the program were also explored.

MATERIALS AND METHODS

Thirty-eight family caregivers were randomized to receive either one massage per week or three massages per week for two weeks. Caregivers reported psychological symptoms and stress pre- and post-program. Program acceptability was assessed via responses on an exit survey.

RESULTS

Overall, 79% of massages were received (89% among program completers). Post-program symptom scores were lower than baseline scores for both groups (F (1, 31) = 8.74 - 24.50, P < 0.01). Exit surveys indicated high program acceptability and perceived benefits.

CONCLUSION

Findings suggest that massage services would be welcomed, utilized, and beneficial for improving the psychological well-being of family caregivers in a rehabilitation hospital.

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.

Conducting Biobehavioral Research in Patients With Advanced Cancer: Recruitment Challenges and Solutions

Despite significant advances in cancer treatment and symptom management interventions over the last decade, patients continue to struggle with cancer-related symptoms. Adequate baseline and longitudinal data are crucial for designing interventions to improve patient quality of life and reduce symptom burden; however, recruitment of patients with advanced cancer in longitudinal research is difficult. Our purpose is to describe challenges and solutions to recruitment of patients with advanced cancer in two biobehavioral research studies examining cancer-related symptoms. Study 1: Symptom data and peripheral blood for markers of inflammation were collected from newly diagnosed patients receiving chemotherapy on the first day of therapy and every 3-4 weeks for up to 6 months. Study 2: Symptom data, blood, and skin biopsies were collected from cancer patients taking epidermal growth factor receptor inhibitors at specific time points over 4 months. Screening and recruitment results for both studies are summarized. Timing informed consent with baseline data collection prior to treatment initiation was a significant recruitment challenge for both the studies. Possible solutions include tailoring recruitment to fit clinic needs, increasing research staff availability during clinic hours, and adding recruitment sites. Identifying solutions to these challenges will permit the conduct of studies that may lead to identification of factors contributing to variability in symptoms and development of tailored patient interventions for patients with advanced cancer.

A screening tool for predicting gatekeeping behaviour

AIM

To develop a typology and screening tool for gatekeeping behaviours by nurses responsible for recruitment in palliative care research.

DESIGN

Concurrent analysis.

METHOD

Two focus groups were conducted in 2015 with nine qualified hospice community nurses involved in recruitment to a trial in palliative care. The literature was searched for research into gatekeeping from 2000-2016. All narrative examples of gatekeeping activity were coded using gerunds. Common codes were then grouped and interpreted as a social process.

RESULTS

Gatekeeping is normal and should be expected. A continuum typology emerged, ranging from unintentional to active disengagement. Justification ranged from forgetting to deliberately not mentioning the study for fear of burdening patients. Viewing gatekeeping as a continuum allowed for the creation of a screening tool designed to collaboratively discuss and hence mitigate specific types of gatekeeping behaviour before they occur. This is a unique international contribution to this persistent issue.

What do we know about different models of providing palliative care? Findings from a systematic review of reviews

BACKGROUND

A wide range of organisational models of palliative care exist. However, decision makers need more information about which models are likely to be most effective in different settings and for different patient groups.

AIM

To identify the existing range of models of palliative care that have been evaluated, what is already known and what further information is essential if the most effective and cost-effective models are to be identified and replicated more widely.

DESIGN

A review of systematic and narrative reviews according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality was assessed using the AMSTAR (A MeaSurement Tool to Assess Reviews) tool.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Library, Web of Science and ASSIA were searched for reviews about models of service provision from 2000 to 2014 and supplemented with Google searches of the grey literature.

RESULTS

Much of the evidence relates to home-based palliative care, although some models are delivered across care settings. Reviews report several potential advantages and few disadvantages of models of palliative care delivery. However, under-reporting of the components of intervention and comparator models are major barriers to the evaluation and implementation of models of palliative care.

CONCLUSION

Irrespective of setting or patient characteristics, models of palliative care appear to show benefits and some models of palliative care may reduce total healthcare costs. However, much more detailed and systematic reporting of components and agreement about outcome measures is essential in order to understand the key components and successfully replicate effective organisational models.

Feasibility of a Telehealth Educational Program on Self-Management of Pain and Fatigue in Adult Cancer Patients

CONTEXT

Pain and fatigue are common symptoms among cancer patients and often lead to substantial distress. Innovative self-management programs for pain and fatigue are needed.

OBJECTIVES

The primary objective was to assess the feasibility of a telehealth pain and fatigue self-management program among adult cancer patients. Secondary objectives included assessment of differences in patient characteristics, recruitment, and retention of patients based on two screening strategies: 1) navigator-collected, patient-reported pain or fatigue and 2) in-clinic, physician-identified pain or fatigue.

METHODS

This prospective, nonrandomized, pre-post evaluation assessed feasibility, which was defined as 50% of eligible patients choosing to participate and completing the intervention. Patient demographics and patient-reported outcomes (patient activation, distress, symptoms, and quality of life) were collected at baseline and study completion. Differences in baseline characteristics were compared between cohorts and for patients who did vs. did not graduate from the program.

RESULTS

The program did not meet feasibility requirements because of only 34% of eligible patients choosing to participate. However, 50% of patients starting the program graduated. Differences in baseline characteristics and retention rates were noted by recruitment strategy. At baseline, 27.3% of navigated patients were at the highest activation level compared with 7.1% in the physician-referred, non-navigated patients (P = 0.17); more than 15% of non-completers were at the lowest activation level compared with 9% of completers (P = 0.85).

CONCLUSION

Telehealth self-management program for pain and fatigue may be better accepted among selected segments of cancer patients. Larger scale studies are needed to assess the efficacy of this program in a more selective activated population.

Cost-effectiveness of zoledronic acid and strontium-89 as bone protecting treatments in addition to chemotherapy in patients with metastatic castrate-refractory prostate cancer: results from the TRAPEZE trial (ISRCTN 12808747)

OBJECTIVE

To evaluate the cost-effectiveness of adding zoledronic acid or strontium-89 to standard docetaxel chemotherapy for patients with castrate-refractory prostate cancer (CRPC).

PATIENTS AND METHODS

Data on resource use and quality of life for 707 patients collected prospectively in the TRAPEZE 2 × 2 factorial randomised trial (ISRCTN 12808747) were used to assess the cost-effectiveness of i) zoledronic acid versus no zoledronic acid (ZA vs. no ZA), and ii) strontium-89 versus no strontium-89 (Sr89 vs. no Sr89). Costs were estimated from the perspective of the National Health Service in the UK and included expenditures for trial treatments, concomitant medications, and use of related hospital and primary care services. Quality-adjusted life-years (QALYs) were calculated according to patients' responses to the generic EuroQol EQ-5D-3L instrument, which evaluates health status. Results are expressed as incremental cost-effectiveness ratios (ICERs) and cost-effectiveness acceptability curves.

RESULTS

The per-patient cost for ZA was £12 667, £251 higher than the equivalent cost in the no ZA group. Patients in the ZA group had on average 0.03 QALYs more than their counterparts in no ZA group. The ICER for this comparison was £8 005. Sr89 was associated with a cost of £13 230, £1365 higher than no Sr89, and a gain of 0.08 QALYs compared to no Sr89. The ICER for Sr89 was £16 884. The probabilities of ZA and Sr89 being cost-effective were 0.64 and 0.60, respectively.

CONCLUSIONS

The addition of bone-targeting treatments to standard chemotherapy led to a small improvement in QALYs for a modest increase in cost (or cost-savings). ZA and Sr89 resulted in ICERs below conventional willingness-to-pay per QALY thresholds, suggesting that their addition to chemotherapy may represent a cost-effective use of resources.

Feasibility, acceptability, and tolerability of RGN107 in the palliative wound care management of chronic wound symptoms

OBJECTIVE

To assess the feasibility, acceptability and tolerability of RGN107 use, a natural powder blend of Arnica Montana, Calendula Officinalis, Mentha Arvensis and Santalum Album, among hospice patients and their wound caregivers in the palliative wound care management of chronic wound symptoms at end-of-life.

METHOD

Data were collected between May 2013 and November 2015. A pilot trial conducted among 50 hospice patients with symptomatic (pain, odour, or exudate) chronic wounds. Caregivers received initial RGN107 protocol training, actively applied the powder to patient wounds for 4-weeks, and completed an 8-week retrospective survey. Feasibility was assessed by measuring process outcomes, including the number and proportion of participants referred, screened eligible, enrolled, withdrawn and successfully completed. Acceptability measures included: a protocol training evaluation, caregiver pre and post self-efficacy ratings, retrospective usability, symptom control management and comparative technique caregiver ratings, and recorded open-ended comments. Tolerability was assessed through a 12-week cumulative review of the study adverse event profile.

RESULTS

Feasibility, tolerability and acceptability of use of the RGN107 powder for chronic wounds were established. Recruitment goals were achieved and 92 % of the patients successfully completed the study. 95 % of wound caregivers would recommend the powder for use in this population.

CONCLUSION

This study supports the feasibility, acceptability and tolerability of a wound care powder that espouses a multi-symptom palliative comfort care approach for hospice patients with chronic wounds at end-of-life. Further research is needed to establish the efficacy of the powder.

Recruiting bereaved parents for research after infant death in the neonatal intensive care unit

Understanding parental experiences following infant death in the neonatal intensive care unit (NICU) is a high research priority and a necessary first step to improving health services. However, recruiting bereaved parents to discuss their experiences on such an extremely sensitive topic can be challenging and research procedures must be planned carefully in order to get an adequate sample. There is little published in the literature detailing specific strategies for recruiting bereaved parents for grief research, especially strategies for contacting parents and identifying factors that might affect participation. The purpose of this paper is to describe the process of recruiting bereaved parents into a qualitative research study exploring parental NICU experiences and grief responses following infant death. We describe a successful recruitment plan that led to the enrollment of difficult to recruit participants such as fathers, and individuals representing minorities and those from lower socioeconomic (SES) groups. Bereaved parents of infants after an NICU hospitalization should continue to be recruited for research studies for their unique perspectives and valuable insights about the devastating experience of infant death. Participants in this study reported more benefits than harm and the results addressed a critical gap in the literature.

Addressing Methodological Challenges in Large Communication Data Sets: Collecting and Coding Longitudinal Interactions in Home Hospice Cancer Care

In this article, we present strategies for collecting and coding a large longitudinal communication data set collected across multiple sites, consisting of more than 2000 hours of digital audio recordings from approximately 300 families. We describe our methods within the context of implementing a large-scale study of communication during cancer home hospice nurse visits, but this procedure could be adapted to communication data sets across a wide variety of settings. This research is the first study designed to capture home hospice nurse-caregiver communication, a highly understudied location and type of communication event. We present a detailed example protocol encompassing data collection in the home environment, large-scale, multisite secure data management, the development of theoretically-based communication coding, and strategies for preventing coder drift and ensuring reliability of analyses. Although each of these challenges has the potential to undermine the utility of the data, reliability between coders is often the only issue consistently reported and addressed in the literature. Overall, our approach demonstrates rigor and provides a "how-to" example for managing large, digitally recorded data sets from collection through analysis. These strategies can inform other large-scale health communication research.

Conducting End-of-Life Studies in Pediatric Oncology

Improving our ability to prevent or diminish suffering in dying children and adolescents and their families is dependent on the completion of high-quality pediatric end-of-life studies. The purpose of this article is to provide useful evidence-based strategies that have been used to implement and complete clinically useful pediatric end-of-life studies in oncology. The article describes specific peer-review and methodological challenges and links those to evidence-based solutions. The challenges and solutions described in this article are from eight end-of-life studies involving pediatric oncology patients. It is hoped that the solutions described here will benefit others in their efforts to implement pediatric end-of-life studies so that clinically useful findings will result and will improve the care of dying children and adolescents.

A systematic review of reasons for gatekeeping in palliative care research

BACKGROUND

When healthcare professionals or other involved parties prevent eligible patients from entering a trial as a research subject, they are gatekeeping. This phenomenon is a persistent problem in palliative care research and thought to be responsible for the failure of many studies.

AIM

To identify potential gatekeepers and explore their reasons for gatekeeping in palliative care research.

DESIGN

A 'Review of Reasons' based on the systematic Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach and a thematic synthesis.

DATA SOURCE

PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO from 2000 to May 20 2015 were searched. Studies in children (aged <18 years) and patients with dementia were excluded.

RESULTS

Thirty papers on gatekeeping in palliative care research were included. Five groups of potential gatekeepers were identified: healthcare professionals, research ethics committees, management, relatives and researchers. The fear of burdening vulnerable patients was the most reported reason for gatekeeping. Other reasons included 'difficulty with disclosure of health status', 'fear of burdening the patient's relatives', 'doubts about the importance or quality of the study', 'reticent attitude towards research and (research) expertise' and 'logistics'. In hospice and homecare settings, the pursuit of comfort care may trigger a protective attitude. Gatekeeping is also rooted in a (perceived) lack of skills to recruit patients with advanced illness.

CONCLUSION

Gatekeeping is motivated by the general assumption of vulnerability of patients, coupled with an emphasis on the duty to protect patients. Research is easily perceived as a threat to patient well-being, and the benefits appear to be overlooked. The patients' perspective concerning study participation is needed to gain a full understanding and to address gatekeeping in palliative care research.

Psychometric evaluation of a Czech version of the Family Inventory of Needs

OBJECTIVE

Identification of areas that family members consider important and in which they need help and support is one of the main goals of palliative care. Our research aimed to assess the psychometric properties of a Czech version of the Family Inventory of Needs (FIN).

METHOD

The group comprised 272 family members of terminally ill cancer patients at the University Hospital in Ostrava. Reliability was assessed by internal consistency (Cronbach's alpha), test-retest reliability, and correlation of both scales and items within the scales (item-total correlation). To verify construct validity, exploratory factor analysis and principal component analysis with a varimax rotation were utilized.

RESULTS

Using exploratory factor analysis, the following four factors (domains) were extracted: basic information, information on treatment and care, support, and comfort of the patient. Cronbach's α for the entire questionnaire was 0.924 on the importance scale and 0.912 for the satisfaction scale; for all domains, a value of α greater than 0.7 was ascertained. Test-retest reliability was also higher than 0.7 for all domains. On the satisfaction scale, a moderate correlation was confirmed between unmet needs in the domains basic information, support, and comfort of the patient, and the total score, and in selected quality-of-life domains.

SIGNIFICANCE OF RESULTS

The results of tests on the psychometric properties of the FIN questionnaire demonstrated at least satisfactory validity and reliability, and confirmed that it can be employed to assess the needs of palliative care patients in the Czech Republic.

Dyadic recruitment in complementary therapy studies: experience from a clinical trial of caregiver-delivered reflexology

PURPOSE

As home-based care continues to be a growing trend in health care, involvement of friend and family caregivers in the management of illness becomes essential. However, before nurses can prepare caregivers to engage in various types of care, an evidence base needs to be established via randomized controlled trials (RCTs). Research suggests that recruiting cancer patients and their friend or family caregivers into RCTs presents challenges. The purpose of this paper is to illustrate the barriers to recruitment of patient-caregiver dyads into a RCT of caregiver-delivered reflexology and to recommend strategies to address such barriers.

METHODS

This paper reports on a nurse-directed RCT that involved recruitment efforts unique to a caregiver-delivered reflexology protocol for advanced-stage breast cancer patients. Ineligibility due to caregiver-related reasons, consent among eligible patients (out of 551 approached patients), and reasons for refusal were analyzed.

RESULTS

Almost one-third of patients were found to be ineligible due to the lack of a caregiver to participate with them and provide this form of social support. Among eligible patients, the consent rate for this dyadic study is much lower than that of previous RCTs of reflexologist-delivered reflexology that enrolled just patients, not dyads.

CONCLUSION

Implications for nursing practice and research include addressing the need for greater social support for patients and strategies for problem-solving refusal reasons during study enrollment.

Feasibility of Conducting a Palliative Care Randomized Controlled Trial in Children With Advanced Cancer: Assessment of the PediQUEST Study

CONTEXT

Pediatric palliative care randomized controlled trials (PPC-RCTs) are uncommon.

OBJECTIVES

To evaluate the feasibility of conducting a PPC-RCT in pediatric cancer patients.

METHODS

This was a cohort study embedded in the Pediatric Quality of Life and Evaluation of Symptoms Technology Study (NCT01838564). This multicenter PPC-RCT evaluated an electronic patient-reported outcomes system. Children aged two years and older, with advanced cancer, and potentially eligible for the study were included. Outcomes included: pre-inclusion attrition (patients not approached, refusals); post-inclusion attrition (drop-out, elimination, death, and intermittent attrition (IA; missing surveys) over nine months of follow-up); child/teenager self-report rates; and, reasons to enroll/participate.

RESULTS

Over five years, of the 339 identified patients, 231 were eligible (in 22, we could not verify eligibility); 84 eligible patients were not approached and 43 declined participation. Patients not approached were more likely to die or have brain tumors. We enrolled 104 patients. Average enrollment rate was one patient per site per month; shortening follow-up from nine to three months (with optional re-enrollment) increased recruitment by 20%. A total of 87 patients completed the study (24 died) and 17 dropped out. Median IA was 41% in the first 20 weeks of follow-up and more than 60% in the eight weeks preceding death. Child/teenager self-report was 94%. Helping others, low burden procedures, incentives, and staff attitude were frequent reasons to enroll/participate.

CONCLUSION

A PPC-RCT in children with advanced cancer was feasible, post-inclusion retention adequate; many families participated for altruistic reasons. Strategies that may further PPC-RCT feasibility include: increasing target population through large multicenter studies, approaching sicker patients, preventing exclusion of certain patient groups, and improving data collection at end of life.

Ethical conduct of palliative care research: enhancing communication between investigators and institutional review boards

Palliative care has faced moral and ethical challenges when conducting research involving human subjects. There are currently no resources to guide institutional review boards (IRBs) in applying standard ethical principles and terms-in a specific way-to palliative care research. Using as a case study a recently completed multisite palliative care clinical trial, this article provides guidance and recommendations for both IRBs and palliative care investigators to facilitate communication and attain the goal of conducting ethical palliative care research and protecting study participants while advancing the science. Beyond identifying current challenges faced by palliative care researchers and IRBs reviewing palliative care research, this article suggests steps that the palliative care research community can take to establish a scientifically sound, stable, productive, and well-functioning relationship between palliative care investigators and the ethical bodies that oversee their work.

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

BACKGROUND

Dignity Therapy is a brief, psychosocial intervention for patients with incurable disease.

AIM

To investigate participation in and evaluation of Dignity Therapy and longitudinal changes in patient-rated outcomes.

DESIGN

A prospective (pre/post) evaluation design was employed. Evaluation questionnaires were completed when patients received the generativity document (T1) and 2 weeks later (T2). Changes from baseline (T0) were measured in sense of dignity, Structured Interview for Symptoms and Concerns items, Patient Dignity Inventory, Hospital Anxiety and Depression Scale and European Organisation for Research and Treatment of Cancer QLQ-C15-PAL (ClinicalTrials.gov number: NCT01507571).

SETTING/PARTICIPANTS

Consecutive patients with incurable cancer, ≥18 years, informed of prognosis and not having cognitive impairment/physical limitations precluding participation were included at a hospice and a hospital palliative medicine unit.

RESULTS

Over 2 years, 80 of 341 eligible patients completed Dignity Therapy. At T1, 55 patients completed evaluations, of whom 73%-89% found Dignity Therapy helpful, satisfactory and of help to relatives; 47%-56% reported that it heightened their sense of purpose, dignity and will to live. Quality of life decreased (mean = -9 (95% confidence interval: -14.54; -2.49)) and depression increased (mean = 0.31 (0.06; 0.57)) on one of several depression measures. At T2 (n = 31), sense of dignity (mean = -0.52 (-1.01; -0.02)) and sense of being a burden to others (mean = -0.26 (-0.49; -0.02)) improved. Patients with children and lower performance status, emotional functioning and quality of life were more likely to report benefit.

CONCLUSIONS

This study adds to the growing body of evidence supporting Dignity Therapy as a valuable intervention in palliative care; a substantial subset of patients facing end of life found it manageable, relevant and beneficial.

Lessons from the field: challenges in accruing hospice heart failure patients to intervention research

Recent clinical practice guidelines suggest that hospice can be a valuable alternative for patients with advanced heart failure (HF). Unfortunately, there are very few evidence-based nursing interventions to guide symptom management for HF patients in hospice and their caregivers. Nevertheless, conducting clinical research in hospice populations remains fraught with methodological and ethical challenges. Our research team was not naive to the fact that hospice research is difficult. We believed that we had prepared well for a number of contingencies before the beginning of our clinical trial testing the feasibility of delivering a psychosocial intervention to caregivers of patients with HF. Despite the team expertise and well-defined recruitment strategies, the recruitment, both accrual and attrition, remained daunting in this population. The purpose of this article was to report the challenges of recruiting hospice patients with HF and caregivers for our randomized clinical trial, those we anticipated and those we did not.

Patient perspectives on informed decision-making surrounding dialysis initiation

BACKGROUND

Careful patient-clinician shared decision-making about dialysis initiation has been promoted, but few studies have addressed patient perspectives on the extent of information provided and how decisions to start dialysis are made.

METHODS

Ninety-nine maintenance dialysis patients recruited from 15 outpatient dialysis centers in North Carolina completed semistructured interviews on information provision and communication about the initiation of dialysis. These data were examined with content analysis. In addition, informed decision-making (IDM) scores were created by summing patient responses (yes/no) to 10 questions about the decision-making.

RESULTS

The mean IDM score was 4.4 (of 10; SD = 2.0); 67% scored 5 or lower. Age at the time of decision-making (r = -0.27, P = 0.006), years of education (r = 0.24, P = 0.02) and presence of a warning about progressing to end-stage kidney disease (t = 2.9, P = 0.005) were significantly associated with IDM scores. Nearly 70% said that the risks and burdens of dialysis were not mentioned at all, and only one patient recalled that the doctor offered the option of not starting dialysis. While a majority (67%) said that they felt they had no choice about starting dialysis (because the alternative would be death) or about dialysis modality, only 21.2% said that they had felt rushed to make a decision. About one-third of the patients perceived that the decision to start dialysis and modality was already made by the doctor.

CONCLUSIONS

A majority of patients felt unprepared and ill-informed about the initiation of dialysis. Improving the extent of IDM about dialysis may optimize patient preparation prior to starting treatment and their perceptions about the decision-making process.

Effectiveness and cost-effectiveness of home palliative care services for adults with advanced illness and their caregivers

BACKGROUND

Extensive evidence shows that well over 50% of people prefer to be cared for and to die at home provided circumstances allow choice. Despite best efforts and policies, one-third or less of all deaths take place at home in many countries of the world.

OBJECTIVES

1. To quantify the effect of home palliative care services for adult patients with advanced illness and their family caregivers on patients' odds of dying at home; 2. to examine the clinical effectiveness of home palliative care services on other outcomes for patients and their caregivers such as symptom control, quality of life, caregiver distress and satisfaction with care; 3. to compare the resource use and costs associated with these services; 4. to critically appraise and summarise the current evidence on cost-effectiveness.

SEARCH METHODS

We searched 12 electronic databases up to November 2012. We checked the reference lists of all included studies, 49 relevant systematic reviews, four key textbooks and recent conference abstracts. We contacted 17 experts and researchers for unpublished data.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series (ITSs) evaluating the impact of home palliative care services on outcomes for adults with advanced illness or their family caregivers, or both.

DATA COLLECTION AND ANALYSIS

One review author assessed the identified titles and abstracts. Two independent reviewers performed assessment of all potentially relevant studies, data extraction and assessment of methodological quality. We carried out meta-analysis where appropriate and calculated numbers needed to treat to benefit (NNTBs) for the primary outcome (death at home).

MAIN RESULTS

We identified 23 studies (16 RCTs, 6 of high quality), including 37,561 participants and 4042 family caregivers, largely with advanced cancer but also congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), HIV/AIDS and multiple sclerosis (MS), among other conditions. Meta-analysis showed increased odds of dying at home (odds ratio (OR) 2.21, 95% CI 1.31 to 3.71; Z = 2.98, P value = 0.003; Chi(2) = 20.57, degrees of freedom (df) = 6, P value = 0.002; I(2) = 71%; NNTB 5, 95% CI 3 to 14 (seven trials with 1222 participants, three of high quality)). In addition, narrative synthesis showed evidence of small but statistically significant beneficial effects of home palliative care services compared to usual care on reducing symptom burden for patients (three trials, two of high quality, and one CBA with 2107 participants) and of no effect on caregiver grief (three RCTs, two of high quality, and one CBA with 2113 caregivers). Evidence on cost-effectiveness (six studies) is inconclusive.

AUTHORS' CONCLUSIONS

The results provide clear and reliable evidence that home palliative care increases the chance of dying at home and reduces symptom burden in particular for patients with cancer, without impacting on caregiver grief. This justifies providing home palliative care for patients who wish to die at home. More work is needed to study cost-effectiveness especially for people with non-malignant conditions, assessing place of death and appropriate outcomes that are sensitive to change and valid in these populations, and to compare different models of home palliative care, in powered studies.

Advancing the science of hospice care: Coalition of Hospices Organized to Investigate Comparative Effectiveness

PURPOSE OF REVIEW

There is very little high-quality evidence to guide clinical practice in hospice care. In the areas of medical therapy, patient-centered and family-centered outcomes, and patient safety, there are numerous high-impact questions for which answers are needed. Although randomized controlled trials are the gold standard for research, such trials are difficult, time consuming, and expensive to conduct in a hospice population. Moreover, they cannot examine the implementation of therapies in real-world settings. Therefore, there is a need for novel, complementary approaches to research in this unique population.

RECENT FINDINGS

This article describes the initial experience of the Coalition of Hospices Organized to Investigate Comparative Effectiveness (CHOICE). CHOICE is a national network of hospices that use electronic health record-based data collection procedures to answer key questions relevant to clinical care and policy. By using a rich source of existing data to conduct observational studies, CHOICE is able to overcome many of the most significant challenges of randomized controlled trials in hospice. However, this approach also created unique challenges related to governance and privacy concerns.

SUMMARY

CHOICE is a growing research network that has the potential to make a contribution to the science of palliative care in a hospice population.

Attrition rates, reasons, and predictive factors in supportive care and palliative oncology clinical trials

BACKGROUND

Attrition is common among supportive care/palliative oncology clinical trials. However, to the authors' knowledge, few studies to date have documented the reasons and predictors for dropout. In the current study, the authors' objective was to determine the rate, reasons, and factors associated with attrition both before reaching the primary endpoint and at the end of the study.

METHODS

A review of all prospective interventional supportive care/palliative oncology trials conducted in the Department of Palliative Care and Rehabilitation Medicine at The University of Texas MD Anderson Cancer Center in Houston between 1999 and 2011 was performed. Patient and study characteristics and attrition data were extracted.

RESULTS

A total of 1214 patients were included in 18 clinical trials. The median age of the patients was 60 years. Approximately 41% had an Eastern Cooperative Oncology Group performance status of ≥ 3, a median Edmonton Symptom Assessment Scale (ESAS) for fatigue of 7 of 10, and a median ESAS for dyspnea of 2 of 10. The attrition rate was 26% (95% confidence interval [95% CI], 23%-28%) for the primary endpoint and 44% (95% CI, 41%-47%) for the end of the study. Common reasons for primary endpoint dropout were symptom burden (21%), patient preference (15%), hospitalization (10%), and death (6%). Primary endpoint attrition was associated with a higher baseline intensity of fatigue (odds ratio [OR], 1.10 per point; P = .01) and a longer study duration (P = .04). End-of-study attrition was associated with higher baseline levels of dyspnea (OR, 1.06; P = .01), fatigue (OR, 1.08; P = .01), Hispanic race (OR, 1.87; P = .002), higher level of education (P = .02), longer study duration (P = .01), and outpatient studies (P = 0.05).

CONCLUSIONS

The attrition rate was high in supportive care/palliative oncology clinical trials, and was associated with various patient characteristics and a high baseline symptom burden. These findings have implications for future clinical trial design including eligibility criteria and sample size calculation.

Conducting the ACTIVE randomized trial in hospice care: keys to success

BACKGROUND

Untreated pain is common for patients at the end of life. Informal caregivers, often family or friends of patients, are responsible for working with hospice staff to provide pain management. Interdisciplinary team meetings conducted in hospices every 2 weeks provide an opportunity for hospice staff to communicate about pain management with informal caregivers of hospice patients.

PURPOSE

We present challenges, solutions, and keys strategies for carrying out a randomized trial in the hospice setting.

METHODS

We are conducting the Assessing Caregivers for Team Intervention through Video Encounters (ACTIVE) study to determine whether regular videoconferencing between hospice patients' informal caregivers and the hospice care team alters caregivers' perceptions of pain management and patients' pain. Participants must be primary caregivers for a hospice patient, at least 18 years of age, capable of providing informed consent, and have access to a computer with a high-speed Internet connection or a telephone. We randomized caregivers to participate in biweekly team meetings through video or phone conferencing (intervention) or to receive usual care from the hospice. All patients receive standard hospice care regardless of the group assignment of their informal caregiver.

RESULTS

As of 1 July 2012, there have been 1038 new admissions to the participating hospices. Of 391 cases in which no contact was made, 233 patients had died or had life expectancy less than 14 days. Home visits were made to 271 interested and eligible caregivers; 249 caregivers of 233 patients were randomly assigned to the usual care or intervention arm. Enrollment is on pace to meet recruitment goals. Lessons Learned Thorough pilot testing of instruments and procedures helped us overcome barriers to conducting research in this vulnerable population. Keys to success included obtaining support from hospice medical directors, including hospice staff in study preparation, minimizing the burden on hospice staff, housing research staff in each participating hospice, using newsletters to enhance communication, developing and maintaining a detailed procedural manual, producing regular data quality reports, developing a secure site to facilitate coding videos for qualitative studies, and holding regular teleconferences with key staff.

LIMITATIONS

Late enrollment of many patients in hospice left little to no time for their caregivers to take part in the intervention. Assisting caregivers of patients with very short life expectancy may require different methods.

CONCLUSIONS

The challenges of conducting randomized trials with hospice patients and caregivers can be addressed with appropriate study design, well-tested research methods, and proactive monitoring of any issues or problems.

Compassion and vigilance: investigators' strategies to manage ethical concerns in palliative and end-of-life research

BACKGROUND

Ethical concerns were identified as a potential barrier to advancing palliative and end-of-life science at the 2004 National Institutes of Health State of the Science Meeting. However, data are lacking about the nature of ethical concerns and strategies for balancing the need to advance science with human subjects protections.

METHODS

A qualitative case-study design was used to follow 43 end-of-life studies from proposal development through the review process and implementation. Investigators participated in semi-structured telephone interviews and provided document data regarding their experiences with grant and IRB reviews. Using constant comparative analysis within and across cases, the investigators identified commonly encountered and unique concerns and strategies for managing these concerns.

FINDINGS

Investigator strategies fell into two broad categories: 1) Recruitment and consent strategies related to subject identification and enrollment; and 2) Protocol-related strategies related to the process of data collection. These strategies shared the overarching meta-themes of compassion, as evidenced by a heightened sensitivity to the needs of the population, coupled with vigilance, as evidenced by close attention to the possible effects of study participation on the participants' well-being, clinical care, and the needs of research staff.

CONCLUSIONS

Ethical concerns have led to the development of compassionate and vigilant strategies designed to balance the potential for risk of harm with the need to advance the science of palliative and end-of-life care. These strategies can be used by investigators to address ethical concerns and minimize barriers to the development of palliative and end-of-life care science.

Longitudinal Pediatric Palliative Care: Quality of Life & Spiritual Struggle (FACE): design and methods

As life expectancy increases for adolescents ever diagnosed with AIDS due to treatment advances, the optimum timing of advance care planning is unclear. Left unprepared for end-of-life (EOL) decisions, families may encounter miscommunication and disagreements, resulting in families being charged with neglect, court battles and even legislative intervention. Advanced care planning (ACP) is a valuable tool rarely used with adolescents. The Longitudinal Pediatric Palliative Care: Quality of Life & Spiritual Struggle study is a two-arm, randomized controlled trial assessing the effectiveness of a disease specific FAmily CEntered (FACE) advanced care planning intervention model among adolescents diagnosed with AIDS, aimed at relieving psychological, spiritual, and physical suffering, while maximizing quality of life through facilitated conversations about ACP. Participants will include 130 eligible dyads (adolescent and family decision-maker) from four urban cities in the United States, randomized to either the FACE intervention or a Healthy Living Control. Three 60-minute sessions will be conducted at weekly intervals. The dyads will be assessed at baseline as well as 3-, 6-, 12-, and 18-month post-intervention. The primary outcome measures will be in congruence with EOL treatment preferences, decisional conflict, and quality of communication. The mediating and moderating effects of threat appraisal, HAART adherence, and spiritual struggle on the relationships among FACE and quality of life and hospitalization/dialysis use will also be assessed. This study will be the first longitudinal study of an AIDS-specific model of ACP with adolescents. If successful, this intervention could quickly translate into clinical practice.

A noninferiority trial of a problem-solving intervention for hospice caregivers: in person versus videophone

PURPOSE OF THE STUDY

Problem-solving therapy (PST) has been found effective when delivered to informal caregivers of patients with various conditions. In hospice, however, its translation to practice is impeded by the increased resources needed for its delivery. The study purpose was to compare the effectiveness of a PST intervention delivered face-to-face with one delivered via videophone to hospice primary caregivers.

DESIGN AND METHODS

The study design was a randomized noninferiority trial with two groups, Group 1 in which caregivers received PST face-to-face, and Group 2 in which caregivers received PST via videophone. Family hospice caregivers were recruited from two urban hospice agencies and received the PST intervention (in three visits for Group 1 or three video-calls in Group 2) in an approximate period of 20 days after hospice admission. Standard caregiver demographic data were collected. Psychometric instruments administered to caregivers at baseline and at study completion included the CQLI-R (Caregiver Quality of Life Index-Revised), the STAI (State-Trait Anxiety Inventory), and the PSI (Problem-Solving Inventory).

RESULTS

One hundred twenty-six caregivers were recruited in the study; 77 were randomly assigned to Group 1 and 49 to Group 2. PST delivered via video was not inferior to face-to-face delivery. The observed changes in scores were similar for each group. Caregiver quality of life improved and state anxiety decreased under both conditions.

CONCLUSIONS

The delivery of PST via videophone was not inferior to face-to-face. Audiovisual feedback captured by technology may be sufficient, providing a solution to the geographic barriers that often inhibit the delivery of these types of interventions to older adults in hospice.

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.

Conducting research with end-of-life populations: overcoming recruitment challenges when working with clinical agencies

Conducting end-of-life (EOL) research can present numerous challenges associated with recruitment and retention of research subjects. Such issues may result from working with a variety of clinical settings or the uniqueness of the patient population. The purposes of this article were to describe recruitment challenges in EOL research when collaborating with different types of clinical agencies and to discuss strategies that are being used to overcome these recruitment issues.

Caregiver symptom burden: the risk of caring for an underserved patient with advanced cancer

BACKGROUND

The growing diversity of the population of the United States and the high burden of cancer-related symptoms reflect the need for caregiver research within underserved groups. In this longitudinal study, the authors assessed changes in symptom severity in caregivers and underserved minority patients diagnosed with advanced solid tumors who were being treated at public hospitals.

METHODS

A total of 85 matched patient-caregiver dyads completed the M. D. Anderson Symptom Inventory 3 times during 20 weeks of chemotherapy. At each time point, symptom severity and interference with daily activities were assessed. Group-based trajectory modeling was used to classify caregivers into high-symptom or low-symptom burden groups.

RESULTS

Sadness and distress were more prevalent among caregivers (P = .005). Symptom burden remained stable among caregivers in the high-symptom group (40%), whereas the low-symptom group (60%) demonstrated a statistically significant decrease over time. Multivariate analysis found being a family-member caregiver (adjusted odds ratio [ADJ-OR], 4.1; 95% confidence interval [95% CI], 1.4-11.6) and caring for a highly symptomatic patient (ADJ-OR, 8.0; 95% CI, 1.5-41.4), rather than race, ethnicity, or sociodemographic characteristics, were significant predictors of the caregiver's membership in the high-symptom burden group.

CONCLUSIONS

Approximately 40% of the caregivers in the current study were found to be at an increased risk for moderate to severe sadness and distress, which remained severe throughout the patient's treatment course at public hospitals. To the authors' knowledge, this study marks the first time that the concept of symptom burden has been used to measure caregiver burden, and the first time that symptom burden has been measured and documented in dyads of caregivers and underserved minority patients.

Recruitment challenges and strategies in a home-based telehealth study

The difficulty in recruiting subjects for home-based telehealth research is well documented. This article shares the recruitment statistics and experiences in the Assessment of Caregivers for Team Intervention via Videophone Encounters pilot study, a home-based telehealth intervention. The study obtained 83% of the desired sample. Challenges included issues with initial inclusion criteria, weather-related problems, timely referrals and follow-up, the enrollment process, the need for multiple visits, and unforeseen cases of multiple caregivers. Detailed monitoring and tracking of recruitment statistics and immediate response to overcome challenges were critical to the eventual recruitment success. Strategies included the reallocation of resources to add a second research site, adjustments in inclusion criteria, process improvement with the hospice admissions process, and strategies to address staff gate-keeping. Recruitment continues to be an important barrier to home-based telehealth research and the sharing of recruitment statistics, challenges, and strategies can be beneficial. Gathering of recruitment data is a critical component of pilot studies, which assists in the development of successful randomized clinical trials for future home-based telehealth research.

A formal feasibility study of sublingual methadone for breakthrough cancer pain

We conducted a feasibility study of sublingual methadone for breakthrough cancer pain, to determine whether a larger, randomized trial was warranted, and to identify a study design that would be likely to succeed. From approximately 1930 patients in the initial pool, nine patients were enrolled. Five patients completed the study, generating data on 83 discrete episodes of breakthrough cancer pain at optimal dose. Mean pain intensity dropped by 1.7 points (on a 10 point numerical scale) within 10 min of sublingual methadone administration, and by 3.2 points after 15 min. No serious or severe toxicity was encountered. Based on the results of this feasibility study, a larger randomized clinical trial of sublingual methadone for breakthrough cancer pain using this trial model would not be successful. Extensive information obtained from small numbers of carefully studied patients provides proof of concept that sublingual methadone is effective, safe, and well tolerated.

Recruiting for end of life research: lessons learned in family research

A main hurdle for end of life research is recruitment of patients. Researchers can enroll interested patients and their families for end of life studies by gaining the trust of the hospice staff, who can make valuable referrals of patients nearing the end of life. Participants in the study should be made as comfortable as possible and not be coerced into the interview process. Once the patients have confidence in the researchers, they are more than willing to be a part of the research process because it can prove to be cathartic to many of the patients and their family members.

Subject Recruitment and Retention against Quadruple Challenges in an Intervention Trial of End-of-Life Communication

Studies of end-of-life care face difficulties associated with enrollment and attrition. Information and exemplars can help end-of-life care researchers anticipate such difficulties and customize recruitment and retention strategies to achieve planned sample sizes. We analyzed data on recruitment and retention efforts used in a clinical trial of an end-of-life communication intervention that involved African American dialysis patients and their chosen surrogate decision makers. Despite the challenges the trial faced (e.g., recruiting a minority group of patients who were seriously ill, had a surrogate decision maker willing to join the study, and were willing to engage in end-of-life discussions), the planned sample size was met, and nearly 90% of the participants completed the study. Various strategies were used to sustain accrual during the study. Although a total of 16 contacts per dyad had been planned from enrollment to 3-months data collection, 27 contacts were actually needed. The strategies and procedures used in this study may be pertinent to other studies that involve African Americans with serious illness and require dyadic participation.

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.

Cancer-related psychosocial research: what are the perspectives of cancer care centre users on participation?

PURPOSE

To explore the perspectives of cancer care centre users on participation in psychosocial research to inform research design and ethics.

METHODS

The study is based on a qualitative research design. Fourteen semistructured interviews were carried in people diagnosed with cancer and carers. The interview included four main questions about practical barriers to participation, types of research design, motivating factors and the conduct of research in a cancer care support setting. The data were analysed using qualitative content analysis.

RESULTS

Interviewees demonstrated a willingness to participate in psychosocial research within certain circumstances. There were no practical barriers identified, although they considered payment for research-related travel important. The most acceptable research design was the face-to-face interview and the least preferred was the randomised control trial. The factors that motivated participation were altruism, valuing research, and making a contribution to the centre. Interviewees supported the conduct of research in cancer care support centres conditional upon delaying recruitment during the initial months of users' visits and its need to be discreet to avoid deterring visitors from accessing the centre.

CONCLUSIONS

The study concludes that the personal interaction between participants and researchers is the most important feature of decision-making by patients/carers to join studies. Taking into account the perspectives of people affected by cancer during the early stages of research design may enhance recruitment and retention and can contribute to the development of research protocols and ethics.

Is it safe? Talking to teens with HIV/AIDS about death and dying: a 3-month evaluation of Family Centered Advance Care (FACE) planning - anxiety, depression, quality of life

Purpose

To determine the safety of engaging HIV-positive (HIV+) adolescents in a Family Centered Advance Care (FACE) planning intervention.

Patients and methods

We conducted a 2-armed, randomized controlled clinical trial in 2 hospital-based outpatient clinics from 2006–2008 with HIV+ adolescents and their surrogates (n = 76). Three 60–90 minutes sessions were conducted weekly. FACE intervention groups received: Lyon FCACP Survey^©, the Respecting Choices^® interview, and completion of The Five Wishes^©. The Healthy Living Control (HLC) received: Developmental History, Healthy Tips, Future Planning (vocational, school or vocational rehabilitation). Three-month post-intervention outcomes were: completion of advance directive (Five Wishes^©); psychological adjustment (Beck Depression, Anxiety Inventories); quality of life (PedsQL^™); and HIV symptoms (General Health Self-Assessment).

Results

Adolescents had a mean age, 16 years; 40% male; 92% African-American; 68% with perinatally acquired HIV, 29% had AIDS diagnosis. FACE participants completed advance directives more than controls, using time matched comparison (P < 0.001). Neither anxiety, nor depression, increased at clinically or statistically significant levels post-intervention. FACE adolescents maintained quality of life. FACE families perceived their adolescents as worsening in their school (P = 0.018) and emotional (P = 0.029) quality of life at 3 months, compared with controls.

Conclusions

Participating in advance care planning did not unduly distress HIV+ adolescents.

Research participation by older adults at end of life: barriers and solutions

The purpose of this article is to elaborate on barriers to research participation by older adults at end of life. We focus on the hospice setting and classify barriers to research participation into six domains: societal attitudes toward death, research procedures, health care organizations, agency staff, patients' families and caregivers, and patient characteristics. We characterize particular participation issues, uncertainties in participation for individuals with advanced illness, and infringements on patient self-determination, as well as potential solutions to these research challenges. Our observation of the complex palliative context includes the realization that a singular change will not have large enough impact on participation. We conclude that, along with the responsibility to expand the research base addressing the needs of dying individuals, there is also a need to understand the challenges of implementing research projects with older adults at end of life.

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.
