Palliative care for patients with end-stage liver disease ineligible for liver transplantation

Chimeric Livers: Interspecies Blastocyst Complementation and Xenotransplantation for End-Stage Liver Disease

Orthotopic liver transplantation (OLT) currently serves as the sole definitive treatment for thousands of patients suffering from end-stage liver disease; and the existing supply of donor livers for OLT is drastically outpaced by the increasing demand. To alleviate this significant gap in treatment, several experimental approaches have been devised with the aim of either offering interim support to patients waiting on the transplant list or bioengineering complete livers for OLT by infusing them with fresh hepatic cells. Recently, interspecies blastocyst complementation has emerged as a promising method for generating complete organs in utero over a short timeframe. When coupled with gene editing technology, it has brought about a potentially revolutionary transformation in regenerative medicine. Blastocyst complementation harbors notable potential for generating complete human livers in large animals, which could be used for xenotransplantation in humans, addressing the scarcity of livers for OLT. Nevertheless, substantial experimental and ethical challenges still need to be overcome to produce human livers in larger domestic animals like pigs. This review compiles the current understanding of interspecies blastocyst complementation and outlines future possibilities for liver xenotransplantation in humans.

National frequency, trends, and healthcare burden of care fragmentation in readmissions for end-stage liver disease in the USA

BACKGROUND

End-stage liver disease (ESLD) patients have frequent readmissions to the same facility or a different hospital (care fragmentation). Care fragmentation results in care delivery from an unfamiliar clinical team or setting, a potential source of suboptimal clinical outcomes. We examined the occurrence, trends, and association between care fragmentation and outcomes during readmissions for ESLD.

METHODS

From the Nationwide Readmissions Database (January to September 2010-2014), we followed adult (age ≥18 years) hospitalizations for ESLD who were discharged alive for 90 days. During 30- and 90-day readmissions, we calculated the frequency, determinants, and clinical outcomes of care fragmentation (SAS 9.4).

RESULTS

Of the 67,480 ESLD hospitalizations surviving at discharge from 2010-2014, 35% (23,872) and 52% (35,549) were readmitted in 30- and 90-days respectively. During readmissions, the frequencies of care fragmentation were similar (30-day: 25.4% and 90-day: 25.8%) and remained stable from 2010 to 2014 (P trends>0.5). Similarly, factors associated with care fragmentation were consistent across 30- and 90-day readmissions. These included ages: 18-44 years, liver cancer, receipt of liver transplantation, hepatorenal syndrome, prolonged length of stay, and hospitalization in non-teaching facilities. During 30- and 90-day readmissions, care fragmentation was associated with higher risk of mortality (adjusted mean ratio: 1.13[1.03-1.24] and 1.14 [1.06-1.23]; P values<0.0001), prolonged length of stay (4.6-days vs. 4.1-days and 5.2-days vs. 4.6-days; P values<0.0001), and higher hospital charges ($36,884 vs. $28,932 and $37,354 vs. $30,851; P values<0.0001).

CONCLUSIONS

Care fragmentation is high among readmissions for ESLD and is associated with poorer outcomes.

Prevalence and risk factors of erectile dysfunction in patients with liver cirrhosis: a systematic review and meta-analysis

BACKGROUND AND AIMS

Liver cirrhosis is associated with an increased risk of developing erectile dysfunction (ED). The aim of this systematic review and meta-analysis was to evaluate the prevalence of ED and its risk factors in male patients with liver cirrhosis.

METHODS

A systematic search of PubMed (Medline), EMBASE, OVID Medline, the Cochrane Library, and other databases was performed for this review. Two investigators reviewed the abstracts obtained from the search and selected manuscripts for full-text review. The event rates were calculated with random-effects model and quality effects model.

RESULTS

Fourteen studies evaluating ED with the International Index of Erectile Function (IIEF) scores were selected. A total of 770 patients with liver cirrhosis were analyzed. The prevalence of ED in cirrhotic patients was 79% [decompensated: 88.4%, CI 35.95-70.84%, I² heterogeneity 85%; compensated: 53.6%, CI 77.64-32%, I² heterogeneity 80%]. Through a meta-regression analysis, we discovered that the presence of decompensation, use of beta-blocker and diuretics were related with ED. In addition, risk factors for ED included high body mass index [odds ratio (OR) 1.13, 95% CI 1.01-1.26], advanced Child-Pugh class (OR 2.29, 95% CI 1.12-4.72), MELD score (OR 1.19, 95% CI 1.05-1.35), diabetes (OR 3.44, 95% CI 1.38-8.57), and hypertension (OR 8.24, 95% CI 1.62-41.99).

CONCLUSION

ED is relatively common in male patients with cirrhosis, and presence of risk factors increases the prevalence of ED.

AGA Clinical Practice Update on Palliative Care Management in Cirrhosis: Expert Review

Care with palliative care principles (aka Palliative Care, PC) is an approach to care that focuses on improving the quality of life of patients and their caregivers who are facing life-limiting illness. It encompasses the assessment and management of symptoms and changes in functional status, the provision of advance care planning and goals of care discussions, prognostication and caregiver support. PC is applicable across the spectrum of cirrhosis regardless of transplant eligibility. Although a common misconception, PC is not synonymous with hospice care. Unfortunately, despite a high symptom burden and challenges with predicting disease course and mounting evidence to support the benefits of PC in patients with cirrhosis, comprehensive PC and referral to hospice are carried out infrequently and very late in the course of disease. In order to meet the needs of our increasingly prevalent cirrhosis population, it is important that all clinicians who care for these patients are able to work together to deliver PC as a standard of care. To date there are limited guidelines/guidance statements to direct clinicians in the area of PC and cirrhosis. Herein we present an evidence-based review of ten Best Practice Advice statements that address key issues pertaining to PC in patients with cirrhosis.

Health Care Utilization and Costs for Patients With End-Stage Liver Disease Are Significantly Higher at the End of Life Compared to Those of Other Decedents

BACKGROUND & AIMS

Patients with end-stage liver disease (ESLD) have progressively complex medical needs. However, little is known about their end-of-life health care utilization or associated costs. We performed a population-based study to evaluate the end-of-life direct utilization and costs for patients with ESLD among health care sectors in the province of Ontario.

METHODS

We used linked Ontario health administrative databases to conduct a population-based retrospective cohort study of all decedents from April 1, 2010, through March 31, 2013. Patients with ESLD were compared with patients without ESLD with regard to total health care utilization and costs in the last year and last 90 days of life.

RESULTS

The median age at death was significantly lower for ESLD decedents (65 y; interquartile range, 56-75 y) than for individuals without ESLD (80 y; interquartile range, 68-88 y). The median cost in the last year of life was significantly greater for patients with ESLD ($51,235 vs $44,456 without ESLD) (P < .001). Median ESLD end-of-life care costs also significantly exceeded those associated with 4 of the 5 most resource-intensive chronic conditions ($69,040 for ESLD vs $59,088 for non-ESLD) (P < .001). Cost differences were most pronounced in the final 90 days of life. During this period, patients with ESLD spent 4.7 more days in the hospital (95% CI, 4.3-5.1 d) than patients without ESLD (P < .0001), had significantly higher odds of dying in an institutional setting (odds ratio, 1.8; 95% CI, 1.7-1.9) (P < .0001), and incurred an additional $4201 in costs (95% CI, $3384-$5019; P < .0001).

CONCLUSIONS

In a population-based study in Canada, we found that patients with ESLD incur significantly higher end-of-life care costs than decedents without ESLD, predominantly owing to increased time in the hospital during the final 90 days of life.

Permanent indwelling peritoneal catheters for palliation of refractory ascites in end-stage liver disease: A systematic review

BACKGROUND & AIMS

The incidence and mortality from end-stage liver disease is increasing, with a minority eligible for liver transplantation. Ascites is the commonest complication of end-stage liver disease and large volume paracentesis (LVP) the accepted management strategy where refractory to medical treatment. In malignant ascites, permanent indwelling peritoneal catheters (PIPC) are an established palliative intervention. The aims are to describe available data using permanent indwelling peritoneal catheters in refractory ascites due to end-stage liver disease.

METHODS

Using systematic review methodology, databases were searched (MEDLINE, EMBASE, CINAHL [The Cumulative Index to Nursing and Allied Health Literature], Google Scholar and Cochrane Database of Systematic Reviews from inception-March 2018), for studies combining ascites and palliative care. Inclusion and exclusion criteria were applied to results.

RESULTS

Following initial and updated searches, 225 studies were identified for full text review, 18 were eligible for final analysis. The studies displayed heterogeneity in design, reported on different indwelling catheters and were overall of low quality. Only one pilot randomised controlled trial was identified, of PIPC versus LVP, recruiting one patient into each arm. Technical insertion success was 100%, with low rates of non-infectious complications (<12%), none life threatening. Rates of bacterial peritonitis were not unacceptably high (12.7%), considering this was an end-stage liver disease population and only a minority utilising long-term prophylactic antibiotics. Only one study attempted quality-of-life assessments; none addressed potential health economic benefits.

CONCLUSIONS

Despite lack of well-designed studies, preliminary data suggests low significant complication rates; however safety and efficacy of permanent indwelling peritoneal catheters in end-stage liver disease remains to be confirmed. Further prospective randomised controlled trials are warranted, potentially translating permanent indwelling peritoneal catheters into improved palliative care in end-stage liver disease.

Mortality in unipolar depression preceding and following chronic somatic diseases

OBJECTIVE

It is largely unknown how depression prior to and following somatic diseases affects mortality. Thus, we examined how the temporal order of depression and somatic diseases affects mortality risk.

METHOD

Data were from a Danish population-based cohort from 1995 to 2013, which included all residents in Denmark during the study period (N = 4 984 912). Nineteen severe chronic somatic disorders from the Charlson Comorbidity Index were assessed. The date of first diagnosis of depression and somatic diseases was identified. Multivariable Cox proportional Hazard models with time-varying covariates were constructed to assess the risk for all-cause and non-suicide deaths for individual somatic diseases.

RESULTS

For all somatic diseases, prior and/or subsequent depression conferred a significantly higher mortality risk. Prior depression was significantly associated with a higher mortality risk when compared to subsequent depression for 13 of the 19 somatic diseases assessed, with the largest difference observed for moderate/severe liver disease (HR = 2.08; 95% CI = 1.79-2.44), followed by metastatic solid tumor (HR = 1.48; 95% CI = 1.39-1.58), and myocardial infarction (HR = 1.40; 95% CI = 1.34-1.49).

CONCLUSION

A particularly high mortality risk was observed in the presence of prior depression for most somatic diseases. Future studies that assess the underlying mechanisms are necessary to adequately address the excessive mortality associated with comorbid depression.

Palliative long-term abdominal drains versus repeated drainage in individuals with untreatable ascites due to advanced cirrhosis: study protocol for a feasibility randomised controlled trial

Background

UK deaths due to chronic liver diseases such as cirrhosis have quadrupled over the last 40 years, making this condition now the third most common cause of premature death. Most patients with advanced cirrhosis (end-stage liver disease [ESLD]) develop ascites. This is often managed with diuretics, but if refractory, then the fluid is drained from the peritoneal cavity every 10–14 days by large volume paracentesis (LVP), a procedure requiring hospital admissions. As the life expectancy of patients with ESLD and refractory ascites (if ineligible for liver transplantation) is on average ≤ 6 months, frequent hospital visits are inappropriate from a palliative perspective. One alternative is long-term abdominal drains (LTADs), used successfully in patients whose ascites is due to malignancy. Although inserted in hospital, these drains allow ascites management outside of a hospital setting. LTADs have not been formally evaluated in patients with refractory ascites due to ESLD.

Methods/design

Due to uncertainty about appropriate outcome measures and whether patients with ESLD would wish or be able to participate in a study, a feasibility randomised controlled trial (RCT) was designed. Patients were consulted on trial design. We plan to recruit 48 patients with refractory ascites and randomise them (1:1) to either (1) LTAD or (2) current standard of care (LVP) for 12 weeks. Outcomes of interest include acceptability of the LTAD to patients, carers and healthcare professionals as well as recruitment and retention rates. The Integrated Palliative care Outcome Scale, the Short Form Liver Disease Quality of Life questionnaire, the EuroQol 5 dimensions instrument and carer-reported (Zarit Burden Interview) outcomes will also be assessed. Preliminary data on cost-effectiveness will be collected, and patients and healthcare professionals will be interviewed about their experience of the trial with a view to identifying barriers to recruitment.

Discussion

LTADs could potentially improve end-of-life care in patients with refractory ascites due to ESLD by improving symptom control, reducing hospital visits and enabling some self-management. Our trial is designed to see if such patients can be recruited, as well as to inform the design of a subsequent definitive trial.

Patient Views on Advance Care Planning in Cirrhosis: A Qualitative Analysis

AIM

To investigate patient experiences and perceptions of advance care planning (ACP) process in cirrhosis.

METHODS

Purposive sampling was used to identify and recruit participants (N = 17) from discrete patient groups: compensated with no prior decompensation, decompensated and not yet listed for transplant, transplant wait listed, medical contraindications for transplant, and low socioeconomic status. Review and discussion of local ACP videos, documents, and experiences with ACP occurred in two individual interviews and four focus groups. Data were analyzed using inductive content analysis including iterative processes of open coding, categorization, and abstraction.

RESULTS

Three overarching categories emerged: (1) lack of understanding about disease trajectories and ACP processes, (2) roles of alternate decision makers, and (3) preferences for receiving ACP information. Most patients desired advanced care-planning conversations before the onset of decompensation (specifically hepatic encephalopathy) with a care provider with whom they had a trusting, preexisting relationship. Involvement of the alternate decision makers was of critical importance to participants, as was the use of direct, easy to understand patient education tools that address practical issues.

CONCLUSION

Our findings support the need for early advance care planning in the outpatient setting. Outpatient clinicians may play a key role in facilitating these discussions.

Advance care planning (ACP) for specialists managing cirrhosis: A focus on patient-centered care

Advance care planning (ACP) and goals of care designation (GCD) are being integrated into modern health care. In cirrhosis, uptake and adoption of these practices have been limited with physicians citing many perceived barriers and limitations. Recognizing the many tangible benefits of ACP and GCD processes in patients with life-limiting chronic diseases, the onus is on health practitioners to initiate and direct these conversations with their patients and surrogates. Drawing upon the literature and our experiences in palliative care and cirrhosis, we provide an actionable framework that can be readily implemented into a busy clinical setting by a practitioner. Conversation starters, visual aids, educational resources (for patients and practitioners), and videos of mock physician-patient scenarios are presented and discussed. Importantly, we have customized each of these tools to meet the unique health care needs of patients with cirrhosis. The inherent flexibility of our approach to ACP discussions and GCD can be further modified to accommodate practitioner preferences.

CONCLUSION

In our clinics, this assemblage of "best practice tools" has been well received by patients and surrogates enabling us to increase the number of outpatients with cirrhosis who have actively contributed to their GCD before acute health events and are supported by well-informed surrogates.

Palliative and end of life care in solid organ transplantation

Palliative care is an interprofessional approach that focuses on quality of life of patients who are facing life-threatening illness. Palliative care is consistently associated with improvements in advance care planning, patient and caregiver satisfaction, quality of life, symptom burden, and lower healthcare utilization. Most transplant patients have advanced chronic disease, significant symptom burden, and mortality awaiting transplant. Transplantation introduces new risks including perioperative death, organ rejection, infection, renal insufficiency, and malignancy. Numerous publications over the last decade identify that palliative care is well-suited to support these patients and their caregivers, yet access to palliative care and research within this population are lacking. This review describes palliative care and summarizes existing research supporting palliative intervention in advanced organ failure and transplant populations. A proposed model to provide palliative care in parallel with disease-directed therapy in a transplant program has the potential to improve symptom burden, quality of life, and healthcare utilization. Further studies are needed to elucidate specific benefits of palliative care for this population. In addition, there is a tremendous need for education, specifically for clinicians, patients, and families, to improve understanding of palliative care and its benefits for patients with advanced disease.

Advanced chronic liver disease in the last year of life: a mixed methods study to understand how care in a specialist liver unit could be improved

OBJECTIVE

To identify the limitations in palliative care provision in the last year of life for people with liver cirrhosis and potential barriers to and enablers of palliative care.

DESIGN

Mixed methods, including a retrospective case note review, qualitative focus groups and individual interviews.

SETTING

A tertiary referral liver centre in the south of England (UK).

PARTICIPANTS

Purposively selected case notes of 30 people with cirrhosis who attended the tertiary referral liver centre and died during an 18-month period; a purposive sample of 22 liver health professionals who participated in either focus groups or individual interviews.

PRIMARY AND SECONDARY OUTCOMES

Data collected from case notes included hospital admissions, documented discussions of prognosis and palliative care provision. Qualitative methods explored management of people with cirrhosis, and barriers to and enablers of palliative care.

RESULTS

Participants had high rates of hospital admissions and symptom burden. Clinicians rarely discussed prognosis or future care preferences; they lacked the skills and confidence to initiate discussions. Palliative care provision occurred late because clinicians were reluctant to refer due to their perception that reduced liver function is reversible, poor understanding of the potential of a palliative approach; palliative care was perceived negatively by patients and families.

CONCLUSIONS

People dying with cirrhosis have unpredictable trajectories, but share a common pathway of frequent admissions and worsening symptoms as death approaches. The use of clinical tools to identify the point of irreversible deterioration and joint working between liver services and palliative care may improve care for people with cirrhosis.

Integration of palliative and supportive care in the management of advanced liver disease: development and evaluation of a prognostic screening tool and supportive care intervention

BACKGROUND AND OBJECTIVES

Patients with decompensated cirrhosis rarely receive palliative and supportive care interventions, which are routine in other life-limiting diseases. We aimed to design and evaluate a prognostic screening tool to routinely identify inpatients with decompensated cirrhosis at high risk of dying over the coming year, alongside the development of a supportive care intervention.

DESIGN

Clinical notes from consecutive patients admitted as an emergency to University Hospitals Bristol with a diagnosis of cirrhosis over two distinct 90-day periods were scrutinised retrospectively for the presence or absence of five evidence-based factors associated with poor prognosis. These were analysed against their ability to predict mortality at 1 year. 'Plan-Do-Study-Act' (PDSA) methodology was used to incorporate poor-prognosis screening into the routine assessment of patients admitted with cirrhosis, and develop a supportive care intervention.

RESULTS

73 admissions were scrutinised (79.5% male, 63% alcohol-related liver disease, median age 54). The presence of three or more poor-prognosis criteria at admission predicted 1-year mortality with sensitivity, specificity and positive predictive value of 72.2%, 83.8% and 81.3%, respectively, and was used as a trigger for implementing the supportive care intervention. Following modification from six PDSA cycles, prognostic screening was integrated into the assessment of all patients admitted with decompensated cirrhosis, with the supportive care intervention (developed simultaneously) instigated for appropriate patients.

CONCLUSIONS

We describe a model of care which identifies inpatients with cirrhosis at significant risk of dying over the coming year, and describe development of a supportive care intervention, which can be offered to suitable patients in parallel to ongoing active management.

Palliative Care Quality Indicators for Patients with End-Stage Liver Disease Due to Cirrhosis

BACKGROUND AND AIMS

There are guidelines for the medical management of cirrhosis and associated quality indicators (QIs), but QIs focusing on standards for palliative aspects of care are needed.

METHODS

We convened a 9-member, multidisciplinary expert panel and used RAND/UCLA modified Delphi methods to develop palliative care quality indicators for patients with cirrhosis. Experts were provided with a report based on a systematic review of the literature that contained evidence concerning the proposed candidate QIs. Panelists rated QIs prior to a planned meeting using a standard 9-point RAND appropriateness scale. These ratings guided discussion during a day-long phone conference meeting, and final ratings were then provided by panel members. Final QI scores were computed and QIs with a final median score of greater than or equal to 7, and no disagreement was included in the final set.

RESULTS

Among 28 candidate QIs, the panel rated 19 as valid measures of quality care. These 19 quality indicators cover care related to information and care planning (13) and supportive care (6).

CONCLUSIONS

These QIs are evidence-based process measures of care that may be useful to improve the quality of palliative care. Research is needed to better understand the quality of palliative care provided to patients with cirrhosis.

Palliative care for cirrhosis: a UK survey of health professionals' perceptions, current practice and future needs

OBJECTIVE

To determine the knowledge and practice patterns of a UK cohort of relevant healthcare professionals (HCPs) about delivering palliative care in cirrhosis, and to inform priorities for future research.

DESIGN

An on-line questionnaire survey with closed and open responses.

SETTING

HCPs identified from the mailing list of special interest groups in hepatology and gastroenterology (liver), general practice and specialist palliative care (SPC) across the UK.

RESULTS

Of the 6181 potential contacts identified, 517 HCPs responded. Most believed a role exists for SPC in caring for people with cirrhosis, but many SPC HCPs felt ill prepared to provide good care to those facing death. Further training was needed in managing liver-related symptoms, symptom control and end of life issues. All HCP groups wished to increase community provision of palliative care support, but many general practitioners felt unable to manage advanced cirrhosis in the community. There were differences in the optimal trigger for SPC referral with liver HCPs less likely to refer at symptom deterioration. Prognostication, symptom management and service configuration were key areas identified for future research.

CONCLUSIONS

All who responded acknowledged the role of SPC in caring for those dying with cirrhosis and need for further training to improve confidence and enable joint working between SPC, general practice and liver teams. Low response rates make it difficult to generalise these findings, which require further validation.

Patient experience of non-malignant ascites and its treatment: a qualitative study

BACKGROUND

Ascites is an accumulation of serous fluid in the abdominal cavity. It can be caused by both malignant and non-malignant conditions and produces distressing symptoms. There have been no qualitative studies looking at the experiences of patients with non-malignant ascites.

AIMS

To explore the experiences of patients living with non-malignant ascites and its management. Also, to explore the views of these patients about services available to them.

METHOD

Phenomenological qualitative research study using digitally recorded semi-structured interviews.

SETTING AND PARTICIPANTS

Six adult patients with non-malignant ascites who were receiving paracentesis to manage their symptoms in an acute hospital day unit.

RESULTS

Participants experienced a wide variety of physical symptoms. They discussed how the ascites impacted on their social lives. They had views on diuretics, low sodium diet and paracentesis as methods of symptom management. Participants' confidence in staff performing paracentesis was a common finding, particularly as ultrasound was rarely used. While only some were suitable for liver transplant, all discussed their future care needs.

CONCLUSION

Participants' experiences of non-malignant ascites are that it has a considerable effect on their quality of life. Patients like the system of day case admission for drainage, but question whether this is sustainable. Advanced practitioners can successfully provide a paracentesis service for these patients in hospitals and potentially this is transferable to hospices. Patients seemed happy to consider the option of semi-permanent drains and pumps as methods of managing ascites.

Managing uncertainty in advanced liver disease: a qualitative, multiperspective, serial interview study

OBJECTIVE

To understand the experiences and support needs of people with advanced liver disease and those of their lay and professional carers to inform improvements in the supportive and palliative care of this rapidly growing but currently neglected patient group.

DESIGN

Multiperspective, serial interviews. We conducted up to three qualitative in-depth interviews with each patient and lay carer over 12 months and single interviews with case-linked healthcare professionals. Data were analysed using grounded theory techniques.

PARTICIPANTS

Patients with advanced liver disease of diverse aetiologies recruited from an inpatient hepatology ward, and their lay carers and case-linked healthcare professionals nominated by the patients.

SETTING

Primary and secondary care in South-East Scotland.

RESULTS

37 participants (15 patients, 11 lay and 11 professional carers) completed 51 individual and 13 joint patient-carer interviews. Nine patients died during the study. Uncertainty dominated experiences throughout the course of the illness, across patients' considerable physical, psychological, social and existential needs and affected patients, lay carers and professionals. This related to the nature of the condition, the unpredictability of physical deterioration and prognosis, poor communication and information-sharing, and complexities of care. The pervasive uncertainty also shaped patients' and lay carers' strategies for coping and impeded care planning. While patients' acute medical care was usually well coordinated, their ongoing care lacked structure and focus.

CONCLUSIONS

Living, dying and caring in advanced liver disease is dominated by pervasive, enduring and universally shared uncertainty. In the face of high levels of multidimensional patient distress, professionals must acknowledge this uncertainty in constructive ways that value its contribution to the person's coping approach. Pervasive uncertainty makes anticipatory care planning in advanced liver disease challenging, but planning 'just in case' is vital to ensure that patients receive timely and appropriate supportive and palliative care alongside effective management of this unpredictable illness.

Integration of palliative care in end-stage liver disease and liver transplantation

BACKGROUND

Patients with end-stage liver disease (ESLD) have a life-limiting illness that causes multiple distressing symptoms and negatively affects quality of life (QOL). This population traditionally has not had much attention within the palliative care community.

DISCUSSION

This article provides an evidence-based review of palliative care issues that patients with ESLD and those awaiting liver transplant face, including approaches to prognosis, symptom management, advance care planning, and end-of-life care.

CONCLUSION

Tremendous opportunity exists to integrate palliative medicine into the care of these patients.

Symptom distress in patients with end-stage liver disease toward the end of life

Research on symptom distress experienced by patients with end-stage liver disease at the end of life is limited. The aims of the study were to describe presence, frequency, severity, and distress of symptoms in patients with end-stage liver disease toward the end of life and to describe the variability in psychological and physical symptom distress between and within patients over time. This study used a prospective, longitudinal descriptive design. Data were collected from 20 patients once a month for up to 6 months. Participants completed the Memorial Symptom Assessment Scale, which reports a total score, a Global Distress Index score, and a psychological and a physical distress score. Patients reported lack of energy, pain, difficulty sleeping, and feeling drowsy as the most frequent, severe, and distressing symptoms. Global Distress Index mean scores (measured on a 1-4 scale) ranged from 2.6 to 2.9 across time. There was notable variability in psychological and physical distress scores between and within patients across time. Gaining knowledge about the prevalent symptoms experienced by patients with end-stage liver disease and the trajectory of these symptoms is crucial for designing interventions that optimize well-being in patients with end-stage liver disease as they are approaching death.

Palliative care for patients with end-stage liver disease

Liver disease results in over four million physician visits and over 750,000 hospitalizations per year in the USA. Those with chronic liver disease frequently progress to cirrhosis, end-stage liver disease (ESLD), and death. Patients with ESLD experience numerous complications, including muscle cramps, confusion (hepatic encephalopathy), protein calorie malnutrition, muscle wasting, fluid overload (ascites, edema), bleeding (esophagogastric variceal hemorrhage), infection (spontaneous bacterial peritonitis), fatigue, anxiety, and depression. Despite significant improvements in palliation of these complications, patients still suffer reduced quality of life and must confront the fact that their disease will often inexorably progress to death. Liver transplantation is a valid option in this setting, increasing the duration of survival and palliating many of the symptoms. However, many patients die waiting for an organ or are not candidates for transplantation due to comorbid illness. Others receive a transplant but succumb to complications of the transplant itself. Patients and families must struggle with simultaneously hoping for a cure while facing a life-threatening illness. Ideally, the combination of palliative care with life-sustaining therapy can maximize the patients' quality and quantity of life. If it becomes clear that life-sustaining therapy is no longer an option, these patients are then already in a system to help them with end-of-life care.

Patients who lack capacity and lack surrogates: can they enroll in hospice?

Patients who lack capacity and lack surrogates are among the most vulnerable patients we care for in palliative care. In the case we present here, we have considered how to make end-of-life decisions for a patient who lacks both capacity and surrogates, who has a terminal illness, and who is not a candidate for disease-modifying treatments. We first define and characterize this population of patients through a review of the literature and then explore some decision-making quandaries that are encountered at the end of life. Finally, we make recommendations on how best to proceed with decision making for this vulnerable population.

Patients with cirrhosis and denied liver transplants rarely receive adequate palliative care or appropriate management

BACKGROUND & AIMS

Patients with cirrhosis who are receiving palliative care and are not eligible for liver transplantation (LT) are often hospitalized multiple times, with lack of expectations or understanding of death and dying. We evaluated how frequently these patients received appropriate and palliative care.

METHODS

We performed a retrospective study of 102 consecutive adult patients (67% men; mean age, 55 years) who were removed from the list for or declined LT from January 2005 through December 2010 at the University of Alberta, Canada. Patients' medical records were reviewed to determine their access to palliative care and relief of symptoms, the appropriateness of the goals for their care, and their requirements for acute care services.

RESULTS

The patients' median Model for End-stage Liver Disease score was 20, and median time from denial of LT to death was 52 days (range, 10-332 days). The most common reasons that patients were removed from the transplant wait list were noncompliance or substance abuse (26%) and severe illness or organ dysfunction (25%). After patients were removed from the list, 17% received renal replacement therapy, and 48% were subsequently admitted to the intensive care unit. Patients spent a median of 14 days (range, 6-33 days) in the hospital after they were removed from the transplant wait list. On the basis of the Edmonton Symptom Assessment System, 65% of patients had evidence of pain, 58% had evidence of nausea, 10% had depression, 36% had anxiety, 48% had dyspnea, and 49% had symptoms of anorexia. Twenty-eight percent of all the patients had documentation of do not resuscitate status on their charts, and only 11% were referred for palliative care.

CONCLUSIONS

Patients with cirrhosis who have been removed from the wait list for LT are infrequently referred for palliative care (∼ 10% of cases), although a high percentage have pain or nausea. Goals of care and do not resuscitate status are rarely discussed. Improved planning of goals of care and access to palliative services are required for these patients.

The utility of the model for end-stage liver disease score: a reliable guide for liver transplant candidacy and, for select patients, simultaneous hospice referral

Patients with chronic liver disease are referred late to hospice or never referred. There are several barriers to timely referral. First, liver transplantation (LT) and hospice care have always been perceived as mutually exclusive. Yet the criteria for hospice referral and for LT are more similar than different (for example, advanced liver disease and imminent death). Second, physicians, patients, and families have not had a reliable metric to guide referral. However, many patients wait for transplantation but never receive an organ. We hypothesized that the Model for End-Stage Liver Disease (MELD) score already in use to prioritize LT could be used in selected patients for concurrent hospice referral. Furthermore, we hypothesized that patients awaiting LT can receive hospice care and remain eligible for transplantation. Patients with advanced or end-stage liver disease were referred to the University of California Davis Health System hospice program. We correlated the MELD score at admission to length of stay (LOS) in hospice. A total of 157 end-stage liver disease patients were admitted to the hospice service. At the time of hospice admission the mean MELD score was 21 (range, 6-45). The mean length of hospice stay was 38 days (range, 1-329 days). A significant correlation was observed between hospice LOS and MELD score at hospice admission (P < 0.01). Six patients were offered a liver graft while on the combined (LT and hospice) program. MELD can be used to guide clinician recommendation to families about hospice care, achieving one of the national benchmark goals of increasing hospice care duration beyond the current median of 2-3 weeks. A higher MELD score might augment physician judgment as to hospice referral. Hospice care for selected patients may be an effective strategy to improve the care of end-stage liver disease patients waiting for LT.

Racial/ethnic disparities in liver transplant surgery and hospice use: parallels, differences, and unanswered questions

Despite well-documented racial/ethnic disparities in liver transplantation and hospice enrollment, reasons for these disparities are unclear. This study was conducted to elucidate what is known and unknown about the underlying causes of racial/ethnic disparities in liver transplantation and hospice enrollment. The root causes of inequities in access to liver transplantation and hospice are as yet poorly understood. Potential contributors to differences include differences in preferences, mistrust of the health care system, geographic factors such as neighborhood, health care system factors such as access to care and managed care versus fee-for-service insurance status, and social factors such as the availability of a full time caregiver. Although the goals of care are different, by examining hospice and transplant surgery side by side in the larger context of health disparities, a number of potentially promising avenues for future research have been uncovered.
