Advance directives in the cardiac care unit

Advance directive screening among veterans with incident heart failure: Comparisons among people aging with and without HIV

BACKGROUND

Heart failure (HF) is common among people aging with HIV (PWH) and without HIV (PWoH). Despite the poor prognosis for HF, advance directives (AD) completion is low but has not been compared among PWH and PWoH.

OBJECTIVES

Determine the prevalence and predictors of AD screening among PWH and PWoH with incident HF.

METHODS

We included Veterans with an incident HF diagnosis code from 2013-2018 in the Veterans Aging Cohort Study (VACS) without prior AD screening. Health records were reviewed for AD screening note titles within -30 days to 1-year post-HF diagnosis. Analyses were stratified by HIV status. Trends in annual AD screening were evaluated with the Cochran-Mantel-Haenszel test. The associations of AD screening with demographics, disease severity (Charlson Comorbidity Index, VACS 2.0 Index), and healthcare encounters (cardiology, palliative care, hospitalization) were evaluated with Cox proportional hazards regression.

RESULTS

HF was diagnosed in 4516 Veterans (28.2% PWH, 71.8% PWoH). Annual AD screening rates increased in both groups (Ptrend<0.0001) and aggregate rates were higher among PWH than PWoH (53.5% vs. 48.2%, p=.001). In both groups, the likelihood of AD screening increased with greater disease severity, palliative care contact, and hospitalization (HR range=1.04-3.32, all p≤.02) but not with cardiology contact (p≥.53).

CONCLUSIONS

AD screening rates after incident HF remain suboptimal but increased over time and were higher in PWH. Future quality improvement and implementation efforts should aim for universal AD screening with incident HF diagnosis, initiated by providers skilled in discussing AD, including in the cardiology subspecialty setting.

Advance directives in patients with head and neck cancer - status quo and factors influencing their creation

Background

Advance Care Planning including living wills and durable powers of attorney for healthcare is a highly relevant topic aiming to increase patient autonomy and reduce medical overtreatment. Data from patients with head and neck cancer (HNC) are not currently available. The main objective of this study was to survey the frequency of advance directives (AD) in patients with head and neck cancer.

Methods

In this single center cross-sectional study, we evaluated patients during their regular follow-up consultations at Germany’s largest tertiary referral center for head and neck cancer, regarding the frequency, characteristics, and influencing factors for the creation of advance directives using a questionnaire tailored to our cohort. The advance directives included living wills, durable powers of attorney for healthcare, and combined directives.

Results

Four hundred and forty-six patients were surveyed from 07/01/2019 to 12/31/2019 (response rate = 68.9%). The mean age was 62.4 years (SD 11.9), 26.9% were women (n = 120). 46.4% of patients (n = 207) reported having authored at least one advance directive. These documents included 16 durable powers of attorney for healthcare (3.6%), 75 living wills (16.8%), and 116 combined directives (26.0%). In multivariate regression analysis, older age (OR ≤ 0.396, 95% CI 0.181–0.868; p = 0.021), regular medication (OR = 1.896, 95% CI 1.029–3.494; p = 0.040), and the marital status (“married”: OR = 2.574, 95% CI 1.142–5.802; p = 0.023; and “permanent partnership”: OR = 6.900, 95% CI 1.312–36.295; p = 0.023) emerged as significant factors increasing the likelihood of having an advance directive. In contrast, the stage of disease, the therapeutic regimen, the ECOG status, and the time from initial diagnosis did not correlate with the presence of any type of advance directive. Ninety-one patients (44%) with advance directives created their documents before the initial diagnoses of head and neck cancer. Most patients who decide to draw up an advance directive make the decision themselves or are motivated to do so by their immediate environment. Only 7% of patients (n = 16) actively made a conscious decision not create an advance directive.

Conclusion

Less than half of head and neck cancer patients had created an advance directive, and very few patients have made a conscious decision not to do so. Older and comorbid patients who were married or in a permanent partnership had a higher likelihood of having an appropriate document. Advance directives are an essential component in enhancing patient autonomy and allow patients to be treated according to their wishes even when they are unable to consent. Therefore, maximum efforts are advocated to increase the prevalence of advance directives, especially in head and neck cancer patients, whose disease often takes a crisis-like course.

Prevalence and correlates of advance care directives among older Australians accessing health and residential aged care services: multicentre audit study

OBJECTIVES

It is important that the outcomes of advance care planning (ACP) conversations are documented and available at the point of care. Advance care directives (ACDs) are a subset of ACP documentation and refer to structured documents that are completed and signed by competent adults. Other ACP documentation includes informal documentation by the person or on behalf of the person by someone else (eg, clinician, family). The primary objectives were to describe the prevalence and correlates of ACDs among Australians aged 65 and over accessing health and residential aged care services. The secondary aim was to describe the prevalence of other ACP documentation.

DESIGN AND SETTING

A prospective multicentre health record audit in general practices (n=13), hospitals (n=12) and residential aged care facilities (RACFs; n=26).

PARTICIPANTS

503 people attending general practice, 574 people admitted to hospitals and 1208 people in RACFs.

PRIMARY AND SECONDARY OUTCOME MEASURES

Prevalence of one or more ACDs; prevalence of other ACP documentation.

RESULTS

29.8% of people had at least one ACD on file. The majority were non-statutory documents (20.9%). ACD prevalence was significantly higher in RACFs (47.7%) than hospitals (15.7%) and general practices (3.2%) (p<0.001), and varied across jurisdictions. Multivariate logistic regression showed that the odds of having an ACD were positively associated with greater functional impairment and being in an RACF or hospital compared with general practice. 21.6% of people had other ACP documentation.

CONCLUSIONS

In this study, 30% of people had ACDs accessible and a further 20% had other ACP documentation, suggesting that approximately half of participants had some form of ACP. Correlates of ACD completion were greater impairment and being in an RACF or hospital. Greater efforts to promote and standardise ACDs across jurisdictions may help to assist older people to navigate and complete ACDs and to receive care consistent with their preferences.

Advance Directives and Powers of Attorney in Intensive Care Patients

BACKGROUND

Advance directives and powers of attorney are increasingly common, yet data on their use in clinical situations remain sparse.

METHODS

In this single center cross-sectional study, we collected data by questionnaire from 1004 intensive care patients in a university hospital. The frequencies of advance directives and powers of attorney were determined, and the factors affecting them were studied with multivariate logistic regression analysis.

RESULTS

Usable data were obtained from 998 patients. 51.3% stated that they had prepared a document of at least one of these two kinds. Among them, 39.6% stated that they had given the relevant document(s) to the hospital, yet such documents were present in the patient's hospital record for only 23%. 508 patients stated their reasons for preparing an advance directive or a power of attorney: the most common reason (48%) was the fear of being at other people's mercy, of the lack of self-determination, or of medical overtreatment. The most important factors associated with a patient's statement that he/she had prepared such a document were advanced age (advance directive: 1.022 [1.009; 1.036], p = 0.001; power of attorney: 1.027 [1.014; 1.040], p<0.001) and elective admission to the hospital (advance directive: 1.622 [1.138; 2.311], p<0.007; power of attorney: 1.459 [1.049; 2.030], p = 0.025). 39.8% of the advance directives and 44.1% of the powers of attorney that were present in the hospital records were poorly interpretable because of the incomplete filling-out of preprinted forms. Half of the patients who did not have such a document had already thought of preparing one, but had not yet done so.

CONCLUSION

For patients hospitalized in intensive care units, there should be early discussion about the presence or absence of documents of these kinds and early evaluation of the patient's concrete wishes in critical situations. Future studies are needed to determine how best to assure that these documents will be correctly prepared and then given over to hospital staff so that they can take their place in the patient's record.

Symptom burden in heart failure: assessment, impact on outcomes, and management

Evidence-based management has improved long-term survival in patients with heart failure (HF). However, an unintended consequence of increased longevity is that patients with HF are exposed to a greater symptom burden over time. In addition to classic symptoms such as dyspnea and edema, patients with HF frequently suffer additional symptoms such as pain, depression, gastrointestinal distress, and fatigue. In addition to obvious effects on quality of life, untreated symptoms increase clinical events including emergency department visits, hospitalizations, and long-term mortality in a dose-dependent fashion. Symptom management in patients with HF consists of two key components: comprehensive symptom assessment and sufficient knowledge of available approaches to alleviate the symptoms. Successful treatment addresses not just the physical but also the emotional, social, and spiritual aspects of suffering. Despite a lack of formal experience during cardiovascular training, symptom management in HF can be learned and implemented effectively by cardiology providers. Co-management with palliative medicine specialists can add significant value across the spectrum and throughout the course of HF.

Protocol for a national prevalence study of advance care planning documentation and self-reported uptake in Australia

INTRODUCTION

Advance care planning (ACP) is a process between a person, their family/carer(s) and healthcare providers that supports adults at any age or stage of health in understanding and sharing their personal values, life goals and preferences regarding future medical care. The Australian government funds a number of national initiatives aimed at increasing ACP uptake; however, there is currently no standardised Australian data on formal ACP documentation or self-reported uptake. This makes it difficult to evaluate the impact of ACP initiatives. This study aims to determine the Australian national prevalence of ACP and completion of Advance Care Directives (ACDs) in hospitals, aged care facilities and general practices. It will also explore people's self-reported use of ACP and views about the process.

METHODS AND ANALYSIS

Researchers will conduct a national multicentre cross-sectional prevalence study, consisting of a record audit and surveys of people aged 65 years or more in three sectors. From 49 participating Australian organisations, 50 records will be audited (total of 2450 records). People whose records were audited, who speak English and have a decision-making capacity will also be invited to complete a survey. The primary outcome measure will be the number of people who have formal or informal ACP documentation that can be located in records within 15 min. Other outcomes will include demographics, measure of illness and functional capacity, details of ACP documentation (including type of document), location of documentation in the person's records and whether current clinical care plans are consistent with ACP documentation. People will be surveyed, to measure self-reported interest, uptake and use of ACP/ACDs, and self-reported quality of life.

ETHICS AND DISSEMINATION

This protocol has been approved by the Austin Health Human Research Ethics Committee (reference HREC/17/Austin/83). Results will be submitted to international peer-reviewed journals and presented at international conferences.

Discussing Advance Care Planning and Directives in the General Population

The concept of end-of-life planning, along with medical and legal issues, has been discussed and has evolved over several years. The 1990 Patient Self-Determination Act and individual states' Department of Health Advance Directive forms helped overcome past problems. Patients with terminal and chronic illness are now able to have their wishes recognized for their future care. Any healthy individual's decision during an advance care planning (ACP) discussion can be adversely affected by various factors; however, multiple barriers-religion, culture, education, and family dynamics-can influence the process. Healthcare professionals' reluctance to initiate the conversation may result from limited training during medical school and residency programs. These limitations hinder both the initiation and productiveness of an ACP conversation. We explored ACP issues to provide guidance to healthcare professionals on how best to address this planning process with a healthy adult.

Mechanical Ventilation Outcomes in Patients With Pulmonary Hypertension in the United States: A National Retrospective Cohort Analysis

OBJECTIVE

The outcome of patients with pulmonary arterial hypertension (PAH) who undergo mechanical ventilation is not well known.

METHODS

The Nationwide Inpatient Sample for 2006 to 2012 was used to isolate patients with a diagnosis of PAH who also underwent invasive (MV) and noninvasive (NIMV) mechanical ventilation. The primary outcome was in-hospital mortality.

RESULTS

The hospital records of 55 208 382 patients were studied, and there were 21 070 patients with PAH, of whom 1646 (7.8%) received MV and 834 (4.0%) received NIMV. Those receiving MV had higher mortality (39.1% vs 12.6%, P < .001) and longer hospital stays (11.9 days, interquartile range [IQR] 6.1-22.2 vs 6.7 days, IQR 3.4-11.9, P < .001) than those undergoing NIMV. Of the patients treated with MV, 4.4% also used home oxygen therapy and had similar overall mortality to those who did not use home oxygen (35.3% vs 39.1%, P = .46). Similarly, there was no relationship between home oxygen use and mortality in patients treated with NIMV (10.6% vs 12.6%, P = .48). Notably, more patients treated with NIMV used home oxygen than those treated with MV (14.4% vs 4.4%, P < .001).

CONCLUSION

Patients with PAH who undergo invasive mechanical ventilation have an in-hospital mortality of 39.1%. Future work may help identify the types of patients who benefit most from advanced respiratory support in a critical care setting.

Advance Care Planning and Goals of Care Communication in Older Adults with Cardiovascular Disease and Multi-Morbidity

This article provides an approach to advance care planning (ACP) and goals of care communication in older adults with cardiovascular disease and multi-morbidity. The goal of ACP is to ensure that the medical care patients receive is aligned with their values and preferences. In this article, the authors outline common benefits and challenges to ACP for older adults with cardiovascular disease and multimorbidity. Recognizing that these patients experience diverse disease trajectories and receive care in multiple health care settings, the authors provide practical steps for multidisciplinary teams to integrate ACP into brief clinic encounters.

'Talk to me': a mixed methods study on preferred physician behaviours during end-of-life communication from the patient perspective

Background

Despite the recognized importance of end‐of‐life (EOL) communication between patients and physicians, the extent and quality of such communication is lacking.

Objective

We sought to understand patient perspectives on physician behaviours during EOL communication.

Design

In this mixed methods study, we conducted quantitative and qualitative strands and then merged data sets during a mixed methods analysis phase. In the quantitative strand, we used the quality of communication tool (QOC) to measure physician behaviours that predict global rating of satisfaction in EOL communication skills, while in the qualitative strand we conducted semi‐structured interviews. During the mixed methods analysis, we compared and contrasted qualitative and quantitative data.

Setting and Participants

Seriously ill inpatients at three tertiary care hospitals in Canada.

Results

We found convergence between qualitative and quantitative strands: patients desire candid information from their physician and a sense of familiarity. The quantitative results (n = 132) suggest a paucity of certain EOL communication behaviours in this seriously ill population with a limited prognosis. The qualitative findings (n = 16) suggest that at times, physicians did not engage in EOL communication despite patient readiness, while sometimes this may represent an appropriate deferral after assessment of a patient's lack of readiness.

Conclusions

Avoidance of certain EOL topics may not always be a failure if it is a result of an assessment of lack of patient readiness. This has implications for future tool development: a measure could be built in to assess whether physician behaviours align with patient readiness.

How to discuss goals of care with patients

Effective communication with patients and their caregivers continues to form the basis of a constructive clinician-patient relationship and is critical to provide patient-centered care. Engaging patients in meaningful, empathic communication not only fulfills an ethical imperative for our work as clinicians but also leads to increased patient satisfaction with their own care and improved clinical outcomes. While these same imperatives and benefits exist for discussing goals of care and end-of-life, communicating with patients about these topics can be particularly daunting. While clinicians receive extensive training on how to identify and treat illness, communication techniques, especially those centering around emotion-laden topics such as end-of-life care, receive short shrift medical education. Fortunately, communication techniques can be taught and learned through deliberate practice, and in this article, we seek to discuss a framework, drawn from published literature and our own experience, for approaching goals-of-care discussions in patients with cardiovascular disease.

Dilemmas in end-stage heart failure

Heart failure (HF), a complex clinical syndrome due to structural or functional disorder of the heart, is a major global health issue, with a prevalence of over 5.8 million in the USA alone, and over 23 million worldwide. As a leading cause of hospitalizations among patients aged 65 years or older, HF is a major consumer of healthcare resources, creating a substantial strain on the healthcare system. This paper discusses the epidemiology of HF, financial impact, and multifaceted predicaments in end-stage HF care. A search was conducted on the U.S. National Library of Medicine website (www.pubmed.gov) using keywords such as end-stage heart failure, palliative care, ethical dilemmas. Despite the poor prognosis of HF (worse than that for many cancers), many HF patients, caregivers, and clinicians are unaware of the poor prognosis. In addition, the unpredictable clinical trajectory of HF complicates the planning of end-of-life care, such as palliative care and hospice, leading to underutilization of such resources. In conclusion, ethical dilemmas in end-stage HF are numerous, embroiling not only the patient, but also the caregiver, healthcare team, and society.

Advance directives among hospitalized patients with heart failure

OBJECTIVES

The purpose of this study was to assess the frequency and correlates of documented advance directives (ADs) among patients hospitalized for heart failure (HF).

BACKGROUND

Discussing ADs with patients with HF is critical for identifying treatment goals consistent with patients' values and preferences and for facilitating health care team communication.

METHODS

We retrospectively identified electronic medical records of adult patients admitted to 2 large tertiary care hospitals with either the primary or secondary discharge diagnosis of HF from September 2008 to August 2013 to assess the presence of ADs in electronic medical records. We performed analyses including HF as either the primary or secondary admission diagnosis and HF as the primary admission diagnosis only. Multivariable models were constructed to investigate independent predictors of documented ADs.

RESULTS

Data included 44,768 admissions from 24,291 individual patients over 5 years. Mean age of patients at admission was 64.8 ± 15.9 years; 47.9% of these patients were female, 51.8% were black. The median length of stay for all admissions was 5 (3 to 10) days; 12.7% of patients had documented ADs. Older age, female sex, white race, higher socioeconomic status, higher risk for adverse in-hospital outcomes, length of stay ≥5 days, hospice discharge, palliative care consultation, and a do-not-resuscitate order were all associated with a significantly higher chance of having documented ADs. A significant increase in ADs over time was noted, but more than 80% of patients did not have ADs in medical records at the end of the study period.

CONCLUSIONS

In a diverse population of hospitalized patients with HF, most did not have a documented AD in the medical records. Although several factors were associated with a higher probability, major opportunities exist for all subgroups of patients with HF to improve documentation of ADs.

Family structure, experiences with end-of-life decision making, and who asked about advance directives impacts advance directive completion rates

BACKGROUND

Advance directives are an important but underutilized resource. Reasons for this underutilization need to be determined.

OBJECTIVE

We investigated factors associated with completion of advance directives among inpatients.

DESIGN

We conducted prospective, structured interviews on family structure, health care, disease, and end-of-life experiences. We compared those with completed advance directives and those without.

SETTING/SUBJECTS

We interviewed 130 inpatients in an urban university hospital.

MEASUREMENTS

We used bivariate analysis and logistic regression to identify characteristics of patients with living wills and health care proxies versus patients without them.

RESULTS

Twenty-one percent of patients had a living will and 35% had a health care proxy. Patients with completed living wills were older (p≤0.0046), had more comorbidities (p=0.018), were widowed (p=0.02), and were more often admitted with chronic disease (p=0.009) compared to those without living wills. Patients with health care proxies were older (p<0.001), had religious affiliations (p=0.04), more children (p=0.03), and more often widowed (p≤0.001) than those without health care proxies. Patients were 10.8 times (95% confidence interval [CI] 4.59-25.3), 46.5 times (95% CI 15.1-139.4), and 68.6 times (95% CI 13.0-361.3) more likely to complete a living will when asked by medical staff, legal staff, or family and friends, respectively, than those not asked. Patients with health care proxies were 1.68 times (95% CI 0.81-3.47), 4.34 times (95% CI 1.50-12.6), and 18.0 times (95% CI 2.03-158.8) more likely to have been asked by the same groups. Patients with experience in end-of-life decision-making were 2.54 times more likely to possess a living will (95%CI 1.01-6.42) and 3.53 times more likely to possess a health care proxy (95% CI 1.51-8.25) than those without experiences.

CONCLUSIONS

Having been asked about advance directives by medical staff, legal staff, or family and friends increases the likelihood that patients will possess an advance directive. Those with prior experience with end-of-life decision-making are more likely to possess an advance directive. Family structure and health care utilization also impacts possession of advance directives.

Ethical challenges in advanced heart failure

PURPOSE OF REVIEW

Advanced heart failure (AHF) is an increasingly important field. Both the population of AHF patients and the therapeutic and diagnostic interventions available are expanding, creating a host of difficult ethical challenges. This article discusses these important issues and proposes an approach to caring for AHF patients.

RECENT FINDINGS

Recent guidelines and clinical trials describe the benefits of costly and invasive therapies for AHF, such as ventricular assist devices and cardiac resynchronization therapy which prolong life and improve symptoms but may create burdens and conflict over deactivation at the end of life. Prognostication, informed consent, and early involvement of palliative care are central to addressing the decision-making challenges raised by these devices. Societal concerns such as cost-effectiveness and distributive justice will play an increasingly important role in the dissemination of these devices.

SUMMARY

More research, increased end-of-life education, emphasis on advance directives, a more comprehensive informed consent process, and a true multidisciplinary approach are needed to provide optimal care for patients with AHF.

Ethics priorities in adult congenital heart disease

The success of modern therapies in congenital heart disease has produced a large and growing population of adults with congenital heart disease as a chronic condition. Such success increasingly raises a host of ethical issues, from resource utilization to end of life decision-making. The importance of a multidisciplinary approach to the care of adult congenital heart disease (ACHD) patients has been emphasized for some time, but addressing the challenges in this population requires a broad range of ethical expertise as well. This paper is based on a conference entitled "Ethical and Policy Challenges in Pediatric and Adult Congenital Heart Disease" held in March of 2012. Herein, we present a compilation of the ethics priorities in ACHD discussed at the conference, including ethical aspects of clinical care, ethics research and policy development in the areas of providing clinical care for challenging ACHD patients, improving transitions from pediatric to adult healthcare systems, advance care planning, and addressing costs.

Advance directives in community patients with heart failure

BACKGROUND

Although it is recommended that all patients with heart failure (HF) have advance directives (AD) in place before the end of life is imminent, the use of AD in HF has not been well studied.

METHODS AND RESULTS

We enrolled consecutive Olmsted County residents presenting with HF from October 2007 through October 2011 into a longitudinal study. Information from AD completed before enrollment and hospitalizations in the month before death were abstracted. Among 608 patients (mean age, 74.0 years; 54.9% men; 65.3%; New York Heart Association functional class 3 or 4), 164 (27.0%) patients died after a mean follow-up of 1.8 years. At enrollment, only 249 (41.0%) patients had an AD. Although most AD appointed a proxy decision-maker (90.4%), less than half addressed wishes regarding use of cardiopulmonary resuscitation (41.4%), mechanical ventilation (38.6%), or hemodialysis (10.0%) at the end of life. The independent predictors of AD completion were older age (adjusted odds ratio [OR] per 10-year increase, 1.82; 95% confidence interval [CI], 1.51–2.20), malignancy (OR, 1.58; 95% CI, 1.05–2.37), and renal dysfunction (OR for estimated glomerular filtration rate <60 mL/min 1.55; 95% CI, 1.05–2.29). At the end of life, patients with AD specifying limits in the aggressiveness of care less frequently received mechanical ventilation (OR, 0.26; 95% CI, 0.07–0.88), with a trend toward decreased intensive care unit admission (OR, 0.45; 95% CI, 0.16–1.29).

CONCLUSIONS

Despite a high mortality rate, over half of patients with HF do not have an AD, and existing AD fail to address important end-of-life medical decisions.

Deactivation of implantable cardioverter defibrillators in terminal illness and end of life care

Cardiology professional societies have recommended that patients with cardiovascular implantable electronic devices complete advance directives (ADs). However, physicians rarely discuss end of life handling of implantable cardioverter defibrillators (ICDs), and standard AD forms do not address the presence of ICDs. We conducted a telephone survey of 278 patients with an ICD from a large, academic hospital. The average period since implantation was 5.15 years. More than 1/3 (38%) had been shocked, with a mean of 4.69 shocks. More than 1/2 had executed an AD, but only 3 had included a plan for their ICD. Most subjects (86%) had never considered what to do with their ICD if they had a serious illness and were unlikely to survive. When asked about ICD deactivation in an end of life situation, 42% said it would depend, 28% favored deactivation, and 11% would not deactivate. One quarter (26%) thought ICD deactivation was a form of assisted suicide, 22% thought a do not resuscitate order did not mean that the ICD should be deactivated, and 46% responded that the ICD should not be automatically deactivated in hospice. The answers did not correlate with any demographic factors. Almost all (95%) agreed that patients should have the opportunity to execute an AD that directs handing of an ICD. When asked who should be responsible for discussing this device for an AD, 31% said electrophysiologists, 45% said general cardiologists, and 14% said primary care physicians. In conclusion, the results of the present study highlight the lack of consensus among patients with an ICD on the issue of deactivation at the end of a patient's life. These findings suggest cardiologists should discuss end of life care and device deactivation with their patients with an ICD.

The use of advance directives among patients with left ventricular assist devices

Patients who undergo implantation of left ventricular assist devices (LVADs) often have improved quality of life, but may eventually succumb to their heart failure and/or sustain LVAD-related complications. In end-of-life situations, decisions must be made about when to deactivate LVAD support. Previous studies have demonstrated that end-of-life planning, particularly with the use of advance directives (ADs), can clarify patients' end-of-life preferences when they are unable to speak for themselves. However, many patients do not have ADs, and among patients who do, the ADs may lack useful information on how to guide care surrogates and clinicians regarding patients' preferences on life-sustaining treatments. The authors retrospectively reviewed the charts of 68 patients with advanced heart failure (56 men [82%]; mean [standard deviation] age, 59.0 ± 12.2 years) who underwent LVAD implantation between March 2003 and January 2009. The indication for the LVAD was destination therapy in 36 (53%) patients and bridge to heart transplant in 32 (47%) patients. Overall, 32 (47%) patients had ADs of varying types; 25 (78%) ADs were completed before LVAD implantation. Although life-sustaining treatments (eg, tube feeding, cardiopulmonary resuscitation, mechanical ventilation, and hemodialysis) were mentioned, none explicitly mentioned the LVAD or withdrawal of LVAD support at the end of life. We hypothesize that if instructions regarding LVAD management in ADs are explicit, surrogate and clinician distress may decrease, and ethical dilemmas may be avoided.

End-of-life care conversations with heart failure patients: a systematic literature review and narrative synthesis

BACKGROUND

Current models of end-of-life care (EOLC) have been largely developed for cancer and may not meet the needs of heart failure patients.

AIM

To review the literature concerning conversations about EOLC between patients with heart failure and healthcare professionals, with respect to the prevalence of conversations; patients' and practitioners' preferences for their timing and content; and the facilitators and blockers to conversations.

DESIGN OF STUDY

Systematic literature review and narrative synthesis.

METHOD

Searches of Medline, PsycINFO and CINAHL databases from January 1987 to April 2010 were conducted, with citation and journal hand searches. Studies of adult patients with heart failure and/or their health professionals concerning discussions of EOLC were included: discussion and opinion pieces were excluded. Extracted data were analysed using NVivo, with a narrative synthesis of emergent themes.

RESULTS

Conversations focus largely on disease management; EOLC is rarely discussed. Some patients would welcome such conversations, but many do not realise the seriousness of their condition or do not wish to discuss end-of-life issues. Clinicians are unsure how to discuss the uncertain prognosis and risk of sudden death; fearing causing premature alarm and destroying hope, they wait for cues from patients before raising EOLC issues. Consequently, the conversations rarely take place.

CONCLUSION

Prognostic uncertainty and high risk of sudden death lead to EOLC conversations being commonly avoided. The implications for policy and practice are discussed: such conversations can be supportive if expressed as 'hoping for the best but preparing for the worst'.
