"Don't get weak in your compassion": bereaved next of kin's suggestions for improving end-of-life care in Veterans Affairs Medical Centers

OBJECTIVES

To analyze bereaved next of kin's suggestions for improving end-of-life (EOL) care in Veterans Affairs (VA) Medical Centers (VAMCs).

DESIGN

Qualitative.

SETTING

This study was part of a larger study testing the effectiveness of a multimodal intervention strategy to improve processes of EOL care in six southeast U.S. VAMCs (Best Practices for End-of-Life Care for Our Nation's Veterans-BEACON Trial).

PARTICIPANTS

Bereaved next of kin (n = 78) of veterans who died between 2005 and 2010.

MEASUREMENTS

Data addressing praise, criticism, and recommendations for enhancing EOL care were abstracted from semistructured interviews of next of kin and aggregated into a code labeled "Suggestions." Content analysis proceeded iteratively through data review, comparison, and negotiation of emergent themes and integration of all coauthors' insights and interpretations into the evolving interpretive scheme.

RESULTS

Next of kin provided examples that resonated with their conceptions of quality EOL care. They also described distressing situations and perceptions of deficits in care. Major themes derived were compassionate care, good communication, support for family visits and privacy, and the need for death preparation and postdeath guidance. The fifth theme, unique to this study, was the salience of the relationship between the veterans and their families and the VA and the expectations this engendered in terms of dignity and honor.

CONCLUSION

Interventions that support staff's ability to convey compassion, communicate information to families and other staff, listen to patients and families, prepare families for the individual's death, and provide consistent, coordinated information regarding after-death activities may optimize EOL hospital care for veterans.

Team-based volunteerism with the seriously ill: a qualitative analysis from 10 volunteers' perspectives

Volunteers offer means through which social workers may extend their ability to support individuals with serious illnesses near the end of life. This study explored the experience of volunteers on teams organized initially as a grassroots movement in response to stigmatized and often socially isolated people with HIV/AIDS dying in the community. Volunteer care teams later expanded to individuals with other serious illnesses. This model spread as a means of meeting the growing need for practical support for seriously ill homebound individuals. Yet, little has been reported in the scientific literature about the interworkings of these teams and their optimal level of functioning. Qualitative inquiry, in the form of semi-structured interviews, explored perspectives of 10 volunteers with experience in volunteer team caring and identified the social processes that shaped their work. The volunteers discussed balance between positive life meaning gained from volunteer work, lessons learned, and negative aspects of a volunteer team approach to caring for the seriously ill in the community. Further investigation is warranted to validate the volunteer care team approach as a cost-effective tool to help seriously ill individuals and caregivers.

Formative evaluation of a multi-component, education-based intervention to improve processes of end-of-life care

A multicomponent, palliative care, education-based intervention was implemented in six Veterans Affairs Medical Centers in the southeast United States. The intervention comprised onsite staff training plus supporting written materials, installation of an electronic order set, and follow-up consultations. Training included large-group didactic presentations, small-group clinical demonstrations, and one-on-one consultations. The intervention strategy was targeted broadly to hundreds of hospital providers, including physician, nursing, and ancillary staff. The purpose was to train staff in identifying actively dying patients and implementing best practices of home-based hospice care. A formative evaluation was conducted utilizing semistructured telephone interviews with key informants from each site. Qualitative data analysis revealed processes that facilitated or impeded uptake of the intervention. Results will be used to inform ongoing and future clinical initiatives and optimize future implementation of education-based interventions to improve adoption of best practices for end-of-life care within acute care settings.

Exploring the affective dimension of the life review process: Facilitators’ interactional strategies for fostering personhood and social value among older adults with early dementia

We employed an auto-ethnography approach to explore the affective dimension of life review sessions with community-dwelling older military veterans with minor cognitive impairment (MCI) and early dementia. Using researchers’ analytic memos, we identified facilitators’ interactional strategies that fostered the participant’s sense of personal identity, dignity and social self-worth. Interaction among participant, caregiver, and facilitators evoked a range of emotional responses, offering a window into the affective world of MCI and early dementia. Positive emotional responses outnumbered negative emotional responses by a ratio of two-to-one in the life review sessions; however, negative emotions were more revelatory of current struggles with declines in health and function. Facilitators utilized two interactional strategies, in particular, to foster personhood and social value of participants: focusing on the participant and creating an empathic connection with the participant. Further work is needed to understand the role of emotions in research interactions and to examine the psychosocial mechanisms through which positive affect functions in promoting identity, personhood and social value among persons with MCI and early dementia.

Opioid pain medication orders and administration in the last days of life

CONTEXT

Most patients with serious and life-limiting illness experience pain at some point in the illness trajectory.

OBJECTIVES

To describe baseline pain management practices for imminently dying patients in Veterans Administration Medical Centers (VAMCs) and examine factors associated with these processes, including presence of opioid orders at the time of death and medication administration in the last seven days, 48 hours, and 24 hours of life.

METHODS

Data on orders and administration of opioid pain medication at the end of life were abstracted from the medical records of veterans who died in six VAMC hospitals in 2005.

RESULTS

Of 1068 patient records, 686 (64.2%) had an active order for an opioid medication at the time of death. Of these, 69.8% of patients had received the medication at some time within the last seven days of life, 61.2% within the last 48 hours, and 47.0% within the last 24 hours. In multivariable models, presence of an order for opioid pain medication at the time of death and administration within the last 24 hours were both significantly associated with having a Do Not Resuscitate (DNR) order (P < 0.0001/0.0002), terminal condition (P < 0.0001/< 0.0001), family presence (P < 0.0001/0.0023), location of death (P = 0.003/0.0005), and having pain noted in the care plan (P = 0.0073/0.0007).

CONCLUSION

Findings indicate a need for improving availability of opioids for end-of-life care in the inpatient setting. Modifiable factors, such as family presence and goals-of-care discussions, suggest potential targets for intervention to improve recognition of the dying process and proactive planning for pain control.

Intrinsic association of widowhood with mortality in community-dwelling older women and men: findings from a prospective propensity-matched population study

OBJECTIVES

Widowhood is associated with increased mortality. However, to what extent this association is independent of other risk factors remains unclear. In the current study, we used propensity score matching to design a study to examine the independent association of widowhood with outcomes in a balanced cohort of older adults in the United States.

METHODS

We used public-use copies of the Cardiovascular Health Study data obtained from the National Heart, Lung, and Blood Institute. Of the 5,795 community-dwelling older men and women aged 65 years and older in Cardiovascular Health Study, 3,820 were married and 1,436 were widows or widowers. Propensity scores for widowhood, estimated for each of the 5,256 participants, were used to assemble a cohort of 819 pairs of widowed and married participants who were balanced on 74 baseline characteristics. The 1,638 matched participants had a mean (± standard deviation) age of 75 (± 6) years, 78% were women, and 16% African American.

RESULTS

All-cause mortality occurred in 46% (374/819) and 51% (415/819) of matched married and widowed participants, respectively, during more than 11 years of median follow-up (hazard ratio associated with widowhood, 1.18; 95% confidence interval, 1.03-1.36; p = .018). Hazard ratios (95% confidence intervals) for cardiovascular and noncardiovascular mortalities were 1.07 (0.87-1.32; p = .517) and 1.28 (1.06-1.55; p = .011), respectively. Widowhood had no independent association with all-cause or heart failure hospitalization or incident cardiovascular events.

CONCLUSIONS

Among community-dwelling older adults, widowhood was associated with increased mortality, which was independent of confounding by baseline characteristics and largely driven by an increased noncardiovascular mortality. Widowhood had no independent association with hospitalizations or incident cardiovascular events.

Thoughts on aneuploidy

Aneuploidy refers to karyotypic abnormalities characterized by gain or loss of individual chromosomes. This condition is associated with disease and death in all organisms in which it has been studied. We have characterized the effects of aneuploidy on yeast and primary mouse cells and found it to be detrimental at the cellular level. Furthermore, we find that aneuploid cells exhibit phenotypes consistent with increased energy need and proteotoxic stress. These observations, together with the finding that the additional chromosomes found in aneuploid cells are active, lead us to propose that aneuploidy causes an increased burden on protein synthesis and protein quality-control pathways and so induces an aneuploidy stress response.

Marital status and health: exploring pre-widowhood

BACKGROUND

Health and function vary by marital status across the life-course, but little is known about older adults approaching spousal loss (pre-widowed).

OBJECTIVE

To explore health and function by marital status focusing on the pre-widowed and to examine factors associated with shorter time to spousal loss. PARTICIPANTS, DESIGN, AND MEASUREMENTS: We used 3 years of data from African American and white community-dwelling older adults in the UAB Study of Aging (N = 1000). Participants were categorized as "continuously married" (married at baseline and 3 years), "widowed" (widowed at baseline), "single" (never married/divorced); and "pre-widowed" (married at baseline and widowed within 3 years). Assessments included sociodemographic characteristics, and measures of depression, anxiety, life-space mobility, and self-reported health. chi(2) and analysis of variance (ANOVA) were used to examine baseline differences. Using Cox regression, we explored factors having independent and significant associations with shorter time to spousal loss among married older adults.

RESULTS

There were significant differences by marital status category for sociodemographic factors, health, and function. Pre-widows differed from other categories by sociodemographic characteristics as well as levels of depression, anxiety and self-reported health. Among married older adults, being female and having lower self-reported health at baseline were independent significant hazards for shorter time to widowhood; while rural residence and providing spousal care were independent significant hazards for a longer progression to widowhood.

CONCLUSIONS

Health deficits associated with spousal bereavement may be evident earlier in the marital transition than previously thought, warranting attention to the health of elderly persons whose spouses have chronic/life-limiting conditions.

Identifying and responding to ethical and methodological issues in after-death interviews with next-of-kin

After-death research with next-of-kin can enhance our understanding of end-of-life care and translate into better services for dying persons and their survivors. This article describes ethical and methodological issues that emerged in a pilot of a face-to-face interview guide designed to elicit next-of-kin's perceptions of end-of-life care. The pilot study was part of a larger Veterans Affairs (VA) Health Services Research protocol to improve end-of-life care in VA Medical Centers. By deconstructing the research process from an ethical perspective and engaging in critical self-assessment, the authors aim to inform other researchers of potential problems involved in after-death research with next-of-kin.

Barriers to mobility during hospitalization from the perspectives of older patients and their nurses and physicians

BACKGROUND

Low mobility is common during hospitalization and is associated with adverse outcomes. Understanding barriers to the maintenance or improvement of mobility is important to the development of successful interventions.

OBJECTIVES

To identify barriers to mobility during hospitalization from the perspectives of older patients and their primary nurses and physicians, to compare and contrast the perceived barriers among these groups, and to make a conceptual model.

DESIGN

Qualitative interviews analyzed and interpreted using a grounded theory approach.

SETTING

Medical wards of a university hospital.

PARTICIPANTS

Twenty-nine participants--10 patients >or= 75 years, 10 nurses, and 9 resident physicians.

MEASUREMENTS

Participants were interviewed using a semistructured interview guide, with similar questions for patients and health care providers. Interviews were audiotaped, transcribed, and reviewed for common themes by independent reviewers. Perceived barriers to mobility were identified, and their nature and frequency were examined for each respondent group.

RESULTS

Content analysis identified 31 perceived barriers to increased mobility during hospitalization. Barriers most frequently described by all 3 groups were: having symptoms (97%), especially weakness (59%), pain (55%), and fatigue (34%); having an intravenous line (69%) or urinary catheter (59%); and being concerned about falls (79%). Lack of staff to assist with out-of-bed activity was mentioned by patients (20%), nurses (70%), and physicians (67%). Unlike patients, health care providers attributed low mobility among hospitalized older adults to lack of patient motivation and lack of ambulatory devices.

CONCLUSIONS

Recognizing and understanding perceived barriers to mobility during hospitalization of older patients is an important first step toward developing successful interventions to minimize low mobility.

What about the trach? Tracheotomy removal as a palliative care maneuver

Tracheotomy is performed on patients with airway obstruction or prolonged mechanical ventilation. Tracheotomy patients are increasingly being referred to hospice and palliative care. This case series describes a process for evaluating the ongoing need for tracheotomy and the impact of tracheotomy removal. A retrospective cohort design was used in which charts were reviewed of all tracheotomy patients referred to the palliative care unit between November 1, 1998, and July 31, 2001. Tracheotomy was present in 13 of 791 palliative care unit admissions. Persistent airway obstruction contraindicated tracheotomy removal in 5 patients. The remaining patients had a successful "button" trial with subsequent tracheotomy removal. They incurred no complications and exhibited improved functional status and decreased symptom burden. Tracheotomy removal is safe and beneficial in this patient subset and should be considered an alternative to prolonged tracheotomy.

Improving processes of hospital care during the last hours of life

BACKGROUND

Known for excellence in care in the last days and hours of life, hospice programs can help individuals have a "good death" and lead to higher family satisfaction with quality of care. Our objective was to evaluate the effectiveness of a multicomponent palliative care intervention based on the best practices of home hospice and designed to improve the quality of care provided for patients dying in an acute care inpatient setting.

METHODS

This study was a before-after intervention trial conducted between 2001 and 2003. Participants included physician, nursing, and ancillary staff on inpatient services of an urban, tertiary care Veterans Affairs medical center. The palliative care intervention included staff education and support to identify patients who were actively dying and implement care plans guided by a comfort care order set template for the last days or hours of life. Data abstracted from computerized medical records of 203 veterans who died during a 6-month period before (n = 108) and after (n = 95) intervention were used to determine the impact of intervention on symptom documentation and 5 process of care indicators.

RESULTS

There was a significant increase in the mean (SD) number of symptoms documented from 1.7 (2.1) to 4.4 (2.7) (P<.001), and the number of care plans increased from 0.4 (0.9) to 2.7 (2.3) (P<.001). Opioid medication availability increased from 57.1% to 83.2% (P<.001), and do-not-resuscitate orders increased from 61.9% to 85.1% (P<.001). There were nonsignificant changes in the proportion of deaths that occurred in intensive care units (P = .17) and in the use of nasogastric tubes (P = .40), and there was a significant increase in the use of restraints (P<.001).

CONCLUSION

Our results indicate that end-of-life care improved after the introduction of the palliative care program.

The Balm of Gilead Project: A Demonstration Project on End-of-Life Care for Safety-Net Populations

The Balm of Gilead is a comprehensive program of end-of-life care for the populations served by the "safety net" public health system in Alabama's largest county. The Balm of Gilead serves terminally ill persons, predominantly of minority ethnic status who as a group are relatively younger than the national hospice population, and typically lacking in personal financial resources. Care provided by the Balm of Gilead addresses the holistic needs associated with terminal illness in each of its stages and each of its treatment settings. Balm of Gilead professionals and volunteers provide continuity of care across a continuum that includes inpatient palliative care, home hospice services, and specialized palliative care in nursing homes and other community residential settings. Cooper Green Hospital and the Jefferson County Department of Health are principal partners in the program. Community partnerships with local foundations, colleges and universities, faith communities, civic groups, and professional groups complete the collaborative network of the Balm of Gilead Project. This report discusses work to date toward fulfilling the project's two primary objectives: (1) to build the infrastructure necessary to support a comprehensive palliative care program that is available to county residents regardless of their ability to pay and (2) to develop systems and services to foster the institutional and community values that promote excellence in end-of-life care. The Project's current status and future challenges are reviewed.

Differential expression of E-cadherin and beta catenin in primary and metastatic Wilms's tumours

BACKGROUND

The E-cadherin-catenin adhesion complex is crucial for intercellular adhesiveness and maintenance of tissue architecture. Its impairment is associated with poorly differentiated phenotype and increased invasiveness of carcinomas.

AIMS

To evaluate E-cadherin, beta catenin, gamma catenin, and ezrin expression and its relation to histopathological features of primary and metastatic Wilms's tumours.

METHODS

Immunohistochemistry was used to determine the expression and cellular distribution of E-cadherin, beta catenin, gamma catenin, and ezrin in primary and metastatic Wilms's tumours. Western blotting was used to determine polypeptide size and expression of E-cadherin and beta catenin in Wilms's tumours compared with normal kidney.

RESULTS

Moderate expression of E-cadherin was found mainly in cytoplasm and occasionally cell membranes of dysplastic tubules, whereas low expression was seen in cytoplasm of blastemal cells. Primary and metastatic tumours showed moderate to high beta catenin expression in blastemal and epithelial cells, with predominantly membranous and cytoplasmic staining. Occasional nuclear staining was noted in metastatic tumours. Low to high gamma catenin and ezrin expression was seen in cytoplasm of blastemal and epithelial cells of primary and metastatic tumours. Higher amounts of 92 kDa beta catenin were detected in tumours than in normal kidney. Low expression of 120 kDa E-cadherin was seen in moderately differentiated tumours, whereas expression was lacking in poorly differentiated tumours.

CONCLUSIONS

Compared with primary tumours, metastatic tumours showed lower expression of E-cadherin and gamma catenin, with nuclear staining for beta catenin. Low E-cadherin was associated with poorly differentiated tumours. These results suggest that abnormal expression of adhesion proteins correlates with the invasive and metastatic phenotype in Wilms's tumours.

Apoptosis and interferons: role of interferon-stimulated genes as mediators of apoptosis

IFNs are a family of cytokines with pleiotropic biological effects mediated by scores of responsive genes. IFNs were the first human proteins to be effective in cancer therapy and were among the first recombinant DNA products to be used clinically. Both quality and quantity of life has been improved in response to IFNs in various malignancies. Despite its beneficial effects, unraveling the mechanisms of the anti-tumor effects of IFN has proven to be a complex task. IFNs may mediate anti-tumor effects either indirectly by modulating immunomodulatory and anti-angiogenic responses or by directly affecting proliferation or cellular differentiation of tumor cells. Both direct or indirect effects of IFNs result from induction of a subset of genes, called IFN stimulated genes (ISGs). In addition to the ISGs implicated in anti-viral, anti-angiogenic, immunomodulatory and cell cycle inhibitory effects, oligonucleotide microarray studies have identified ISGs with apoptotic functions. These include TNF-alpha related apoptosis inducing ligand (TRAIL/Apo2L), Fas/FasL, XIAP associated factor-1 (XAF-1), caspase-4, caspase-8, dsRNA activated protein kinase (PKR), 2'5'A oligoadenylate synthetase (OAS), death activating protein kinases (DAP kinase), phospholipid scramblase, galectin 9, IFN regulatory factors (IRFs), promyelocytic leukemia gene (PML) and regulators of IFN induced death (RIDs). In vitro IFN-alpha, IFN-beta and IFN-gamma induced apoptosis in multiple cell lines of varied histologies. This review will emphasize possible mechanisms and the role of ISGs involved in mediating apoptotic function of IFNs.

Mre11 complex and DNA replication: linkage to E2F and sites of DNA synthesis

We show that the Mre11 complex associates with E2F family members via the Nbs1 N terminus. This association and Nbs1 phosphorylation are correlated with S-phase checkpoint proficiency, whereas neither is sufficient individually for checkpoint activation. The Nbs1 E2F interaction occurred near the Epstein-Barr virus origin of replication as well as near a chromosomal replication origin in the c-myc promoter region and was restricted to S-phase cells. The Mre11 complex colocalized with PCNA at replication forks throughout S phase, both prior to and coincident with the appearance of nascent DNA. These data suggest that the Mre11 complex suppresses genomic instability through its influence on both the regulation and progression of DNA replication.

Functional classification of interferon-stimulated genes identified using microarrays

Interferons (IFNs) are a family of multifunctional cytokines that activate transcription of subsets of genes. The gene products induced by IFNs are responsible for IFN antiviral, antiproliferative, and immunomodulatory properties. To obtain a more comprehensive list and a better understanding of the genes regulated by IFNs, we compiled data from many experiments, using two different microarray formats. The combined data sets identified >300 IFN-stimulated genes (ISGs). To provide new insight into IFN-induced cellular phenotypes, we assigned these ISGs to functional categories. The data are accessible on the World Wide Web at http://www.lerner.ccf.org/labs/williams/, including functional categories and individual genes listed in a searchable database. The entries are linked to GenBank and Unigene sequence information and other resources. The goal is to eventually compile a comprehensive list of all ISGs. Recognition of the functions of the ISGs and their specific roles in the biological effects of IFNs is leading to a greater appreciation of the many facets of these intriguing and essential cytokines. This review focuses on the functions of the ISGs identified by analyzing the microarray data and focuses particularly on new insights into the protein kinase RNA-regulated (PRKR) protein, which have been made possible with the availability of PRKR-null mice.

Signal integration via PKR

The vital role of interferons (IFNs) as mediators of innate immunity is well established. It has recently become apparent that one of the pivotal proteins in mediating the antiviral activity of IFNs, the double-stranded RNA (dsRNA)-activated protein kinase (PKR), also functions as a signal transducer in the proinflammatory response to different agents. PKR is a member of a small family of kinases that are activated by extracellular stresses and that phosphorylate the alpha subunit of protein synthesis initiation factor eIF-2, thereby inhibiting protein synthesis. The activation of PKR during infection by viral dsRNA intermediates results in the inhibition of viral replication. PKR also mediates the activation of signal transduction pathways by proinflammatory stimuli, including bacterial lipopolysaccharide (LPS), tumor necrosis factor alpha (TNF-alpha), and interleukin 1 (IL-1). PKR is a component of the inhibitor of kappaB (IkappaB) kinase complex and plays either a catalytic or structural role in the activation of IkappaB kinase, depending on the stimulus. The activities of the stress-activated protein kinases p38 and c-Jun NH(2)-terminal kinase (JNK) are also regulated by PKR in a pathway that leads to the production of proinflammatory cytokines. This review will focus on the role of PKR in nuclear factor kappa B (NF-kappaB) and mitogen-activated protein kinase (MAPK) pathways, because these have been the subjects of a series of publications over the past year that have reported conflicting findings. Although the conflicts may not be resolved in this review, suggestions are made for experiments that could lead to a clearer understanding of the mechanisms involved.

RNA-dependent protein kinase PKR is required for activation of NF-kappa B by IFN-gamma in a STAT1-independent pathway

The IFN-inducible dsRNA-activated protein kinase PKR regulates protein synthesis through phosphorylation of eukaryotic initiation factor-2alpha. It also acts as a signal transducer for transcription factors NF-kappaB, IFN regulatory factor-1, and activating transcription factor-2. IFN-gamma, a pleiotropic cytokine, elicits gene expression by activating the Janus kinase-STAT signaling pathway. IFN-gamma can synergize with TNF-alpha to activate NF-kappaB in a number of cell lines. Here we show that IFN-gamma alone can activate NF-kappaB, by a Janus kinase-1-mediated, but Stat1-independent, mechanism. NF-kappaB activation by IFN-gamma is associated with degradation of IkappaB beta. The IFN-gamma response can be blocked by 2',5'-oligoadenylate-linked antisense chimeras against PKR mRNA. There was no activation of NF-kappaB by IFN in PKR-null cells, indicating that PKR is required for IFN-gamma signaling to NF-kappaB.

ARED: human AU-rich element-containing mRNA database reveals an unexpectedly diverse functional repertoire of encoded proteins

The adenylate uridylate-rich elements (AREs) mediate the rapid turnover of mRNAs encoding proteins that regulate cellular growth and body response to exogenous agents such as microbes, inflammatory and environmental stimuli. However, the full repertoire of ARE-containing mRNAs is unknown. Here, we explore the distribution of AREs in human mRNA sequences. Computational derivation of a 13-bp ARE pattern was performed using multiple expectation maximization for motif elicitations (MEME) and consensus analyses. This pattern was statistically validated for the specificity towards the 3'-untranslated region and not coding region. The computationally derived ARE pattern is the basis of a database which contains non-redundant full-length ARE-mRNAs. The ARE-mRNA database (ARED; http://rc.kfshrc.edu.sa/ared) reveals that ARE-mRNAs encode a wide repertoire of functionally diverse proteins that belong to different biological processes and are important in several disease states. Cluster analysis was performed using the ARE sequences to demonstrate potential relationships between the type and number of ARE motifs, and the functional characteristics of the proteins.
