Primary palliative care for heart failure: What is it? How do we implement it?

Abstract

Heart Failure (HF) is a chronic and progressive illness, which affects a growing number of adults and is associated with a high morbidity and mortality, as well as significant physical and psychological symptom burden on both patients with HF and their families. Palliative care is the multidisciplinary specialty focused on optimizing quality of life and reducing suffering for patients and families facing serious illness, regardless of prognosis. Palliative care can be delivered as (1) specialist palliative care in which a palliative care specialist with subspecialty palliative care training consults or co-manages patients to address palliative needs alongside clinicians who manage the underlying illness or (2) as primary palliative care in which the primary clinician (such as the internist, cardiologist, cardiology nurse or HF specialist) caring for the patient with HF provides the essential palliative domains. In this paper, we describe the key domains of primary palliative care for patients with HF and offer some specific ways in which primary palliative care and specialist palliative care can be offered in this population. Although there is little research on HF primary palliative care, primary palliative care in HF offers a key opportunity to ensuring this population receives high quality palliative care in spite of the growing numbers of patients with HF as well as the limited number of specialist palliative care providers.

Introduction

Heart failure (HF) is a chronic, progressive, and debilitating epidemic that afflicts more than 6 million American adults, while another 870,000 individuals are diagnosed annually.¹ Despite improved survival conferred by medical therapy², nearly 40% of patients will die within a year of first hospitalization.³ During their course of illness, patients with HF suffer from major physical and psychological burdens,^4–6 dramatic functional limitations,⁷ and an unpredictable trajectory^8,9—all of which impair patients’ and caregivers’ quality of life (QOL).^5,7 Physical symptoms in advanced HF, which include pain, breathlessness, fatigue, depression, anorexia, among others, are highly distressing for patients and caregivers, yet remain under-recognized and undertreated.^10,11 In fact, the symptom burdens among patients with advanced HF have been found to exceed those reported by patients with advanced cancer.^6,12–16 Further, the management of HF poses enormous burden, both financial and non-financial, on families, healthcare systems, and society. In 2030, direct medical costs of HF are projected to be $77.7 billion, a 215% increase from current spending.¹⁷ Finally, patients and their caregivers often face decisions about high-risk and complex treatments^18,19 (e.g. cardiac devices, transplantation) without adequate prognosis communication, decision support, or advance care planning.^20,21

Palliative care is the multidisciplinary specialty focused on optimizing QOL and reducing suffering for patients and families affected by serious illness, regardless of prognosis.²² Palliative care includes pain and symptom management; psychological, spiritual, and social support; assistance with treatment decision-making; and complex care coordination.²³ In a systematic review and meta-analysis of randomized palliative care interventions,²⁴ palliative care was found to be associated with improved survival,²⁵ increased QOL,^25,26 decreased symptom burden,²⁷ decreased healthcare expenditures,²³ as well as improved caregiver outcomes such as burden and mood²⁸; however, the overwhelming majority of this evidence emanates from oncology populations. It is only recently that several studies of palliative care interventions in HF have shown improvement in QOL^29,30, symptom burden^29–32, mood^29,33, and healthcare utilization^30,32,34 for patients with HF. Heightened recognition of the role of palliative care in the management of HF has called for high-quality palliative care research to better understand the effect of integrating palliative care in the management of HF.^24,35–37

Palliative care can be delivered in one of two ways, distinguished by provider specialization.³⁸ First, specialist palliative care is the consultation or co-management of patients to address palliative needs alongside clinicians who manage the underlying illness by a clinician who completed a one-year palliative care fellowship or certification. Alternatively, primary palliative care (aka “generalist palliative care”) involves the provision of essential palliative domains by a clinician without palliative care subspecialty training (i.e. an internist caring for patients with HF, a cardiologist, a cardiology nurse or a HF specialist.) To date, research in HF palliative care has been largely limited to specialist palliative care models and no research exists on primary palliative care.

Although recommended by all major cardiology societies for patients with advanced HF, specialist palliative care for all eligible patients is currently neither a feasible nor a scalable strategy.^36,39–44 Regrettably, patients with HF rarely receive specialist palliative care.⁴⁵ First, research^46–48, including ours^49,50, has demonstrated barriers to referring patients with HF for specialist palliative care, such as the misperception that palliative care is only for patients at the very end of life; the unpredictable course of HF and related difficulty of prognostication; the lack of clear referral triggers across the HF trajectory; the ambiguity regarding what differentiates standard HF therapy from palliative care; and the uncertainty regarding the optimal time for referral to palliative care.⁴⁹

Second, and to the purpose of this article, there is a growing shortage of palliative care specialists.⁵¹ It has been estimated that while there is approximately one cardiologist for every 71 persons experiencing a heart attack and one oncologist for every 141 newly diagnosed cancer patients, there is only one palliative medicine physician for every 1,200 persons living with a serious or life-threatening illness.⁵² Approximately 18,000 additional palliative care physicians are needed to meet inpatient consultation needs alone.⁵³ While there is certification in palliative care for nurse practitioners, there is similarly an insufficient workforce to meet the growing needs of patients with serious illness and their families.

Specialist palliative care³⁸ comprises palliative care skills in management of refractory symptoms and assistance with complex decision-making and conflict resolution. Specialist palliative care services are provided in a number of inpatient and outpatient settings with a variety of models. Although specialist palliative care has been demonstrated to improve quality of care for patients and their families, and reduce cost, the workforce shortage limits the potential for specialist palliative care to meet the needs of this population. Innovations are needed to integrate palliative care principles within usual HF care – in other words, to promote the diffusion of primary palliative care into HF.

Primary palliative care is a potentially feasible, scalable, and generalizable solution to meet the needs of patients with HF.^38,54 Traditional HF disease management strategies represent potential vehicles through which to infuse palliative principles into usual HF care. Primary palliative care, including symptom management, communication, psychosocial support, and care coordination, with overall goal of alleviating suffering, should arguably be a part of comprehensive HF care (see Table 1); yet, these processes are often not the focus of HF management. Indeed, multiple aspects of primary palliative care (e.g., care coordination, decision support) align with principles of disease management.⁵⁵ Furthermore, many patients with HF may not have complex or intractable needs requiring a palliative care specialist (see Table 1), yet still would benefit from the integration of primary palliative care in their HF treatment program.³⁸ Research is needed to examine the outcomes from the integration of primary palliative care into internal medicine and cardiology clinics, while reserving specialist palliative care for patients with complex needs.

Need for Primary Palliative Care Training for Patients with HF

Due to the limitations in the numbers of the specialist palliative care workforce, there is a growing demand for primary palliative care training for those who care for patients with serious illness and their families. A recent paper outlines the core competencies in palliative care for cardiology fellows training to include 1) prognostication, 2) communication, 3) discussing goals of care, end-of-life care and resuscitation status, 4) understanding what palliative care is, 5) timely referral to palliative care, 6) symptom palliation and 7) deactivation of rhythm control devices.⁵⁶ Similarly, the recent 2015 American College of Cardiology (ACC) Core Cardiology Training Statement recognizes the need for training in primary palliative care. Specifically, under Medical Knowledge, the training guidelines include the “need to know the principles, modalities, and appropriate indications for palliative care.”⁵⁷ Under HF Disease Management, training in end-of-life care is recommended including communication of care options and participation in an interdisciplinary palliative care team.⁵⁷ Finally, under Professionalism, there is discussion that trainees should be able to clearly and objectively discuss the therapies available for advanced HF, including palliative care, transplant, or mechanical circulatory support.”⁵⁷ Guidelines as to how palliative care training is to be integrated for the Advanced HF fellow are not specified. While there is specialty training available for physicians, nurses and nurse practitioners in cardiology and in HF, none of those programs has a formal component that provides training in primary palliative care.

Because there is a limited number of specialist palliative care clinicians, it is not feasible to provide specialist palliative care to patients with HF by an interdisciplinary care team. Given this gap in workforce, future research will need to determine how high-quality palliative care can be delivered by general cardiologists, HF specialists as well as nurses, social workers, and other clinicians who are integrated within the HF team. The development of high quality primary palliative care is particularly important for HF given its rapidly increasing incidence, high morbidity and mortality, and the complex decision-making in advanced stages involving consideration of ventricular assist devices therapies, cardiac transplant and hospice. Because the vast majority of these patients are cared for by primary cardiologists in the community and not advanced HF teams in academic medical centers, new models will need to address how to treat patients across a variety of health care settings. Finally, research is required to identify ways to motivate HF clinicians to devote the time and resources to integrate training in primary palliative care into their education. By improving the evidence base and providing education, HF clinicians will likely be prompted to receive primary palliative care training, as we have seen in the field of oncology.

Primary Palliative Care Domains for Patients with HF

The domains of primary palliative care include management of basic symptoms, communication regarding goals of care and advanced care planning, and psychological support and care coordination. These individual domains are discussed in detail in the paragraphs that follow and are outlined in the middle column of Table 1.

Management of Basic Symptoms

The most common symptoms of HF are pain, breathlessness, anxiety, fatigue, and depression, of which the majority of patients describe at least one symptom as burdensome.⁵⁸ Many of these patients leave the hospital with suboptimal symptom control due to lingering congestion, which can last for weeks to months.⁵⁹ Because addressing symptoms is often the mainstay of HF management, with basic education, HF clinicians can also be alerted to identify and treat other symptoms, such as uncomplicated depression, anxiety and pain. Specialist palliative care may still be appropriate for complex or refractory symptoms.

Communication Regarding Goals of Care and Advance Care Planning

Patients with HF rarely complete advance directives. In one study of community dwelling patients with HF, only 41% had an advance directive; the vast majority (90%) of these was durable powers of attorney for health care (healthcare proxy).⁶⁰ In another study assessing the presence of advanced directives in electronic medical records of adult patients admitted with HF to 2 large tertiary care hospitals, only 12.7% had a documented advance directive at the time of the last admission.⁶¹

Unfortunately, even when completed, these documents rarely address patients’ goals of care. The forms are often completed without a conversation about patient’s preferences for treatment.⁶² Identification of a healthcare proxy is an important aspect of advance care planning, but it is not sufficient without a discussion about treatment preferences, especially given the myriad therapies available to patients with HF.

Unfortunately, a lack of early communication about prognosis and goals leads to unwanted treatment in some cases and very late decisions near the time of death. For patients with HF, data demonstrate that decisions about preferences for resuscitation are made close to death. Among community-based patients with HF, at enrollment 73.4% were Full Code, and at death 78.5% had Do Not Resuscitate (DNR) orders. These orders are placed a median time of 37 days before death.⁶³ These orders may mean that conversations about end-of-life care may be occurring only weeks before death for community-based patients with HF. There is even less evidence regarding the use of out of hospital physician orders for life-sustaining treatment (“out of hospital DNRs”) in the HF population.

Patients with HF and their caregivers face an additional layer of complexity in decision-making at the end of life given the various cardiac devices that are used to prolong life including automatic implantable cardioverter-defibrillator and mechanical circulatory support. Therefore, decision-making for this population includes not only the implementation of these devices but also discussions about deactivation of these devices in the appropriate clinical circumstances. Ideally, patients should be encouraged to execute advance directives with device-specific language to ensure that they receive care consistent with their preferences.^64–66 Efforts to foster completion of comprehensive advance directives that address goals of care are needed desperately for patients with HF well in advance of death.

Under the primary palliative care domain of communication and advance care planning, two key tasks include identification of a surrogate decision-making, guidance about filling out an advance directive (healthcare proxy, living will) and exploring goals and values and discussing prognosis. The goal of these discussions is to assure that treatments, such as defibrillator, mechanical circulatory support, inotropes, and resuscitation, are aligned with patient’s goals and values. It is important to acknowledge that leading these discussions can be both emotionally taxing and time consuming.

As medical school, medical residency and nursing curricula have evolved, many HF clinicians are likely to have been exposed to basic education in communication skills, as a means to facilitate having these discussions. Nevertheless, there are many instances in which there is added complexity, which could serve as a signal to involve specialtist palliative care. Such signals might include conflict between the patient and family, conflict among the clinical care team or ambiguity about which treatment options might best match goals and values due to existential distress. In these instances, the involvement of specialist palliative care can offer the necessary communication skills to navigate these more complex and challenging conversations.

Psychosocial Support and Care Coordination

Caregivers of patients with advanced HF also face a tremendous burden. Indeed the estimated annual informal caregiving cost attributable to HF was $3 billion in 2010.⁶⁷ In addition to partnering in complex medical decisions, family members or friends often take on the responsibilities of assessing symptoms, administrating medications, assisting in the management of advanced HF therapies and devices (e.g. mechanical circulatory support, wearable defibrillators, and/or heart transplants) and providing emotional support. Likewise, they coordinate care and assist with activities of daily living, such as transportation to office visits and diagnostic procedures. Ultimately, they will need bereavement support following their loved ones’ death. Overall data about the caregiving burdens related to HF are limited.

One qualitative study of caregivers of patients with a destination therapy LVAD demonstrated the burdens of caregivers; specifically, participants described a process of adjusting and adapting to their new roles, amid persistent worry and stress, and eventually accepting caregiving as part of life.⁶⁸ In another qualitative study of bereaved caregivers of patients with an LVAD, the participants shared a high level of confusion at the end of life.⁶⁹ These caregivers are at high risk for the hazards of caregiving for patients with serious illness, including anxiety, depression, poor quality of life, complicated bereavement and high costs of care.

With primary palliative care training, HF clinicians caring could better identify those patients and caregivers at risk for these symptoms of anxiety, depression and complicated grief, and ensure that they are referred to appropriate sources of support such as social workers and chaplains. By conducting earlier goals of care discussions and providing prognostic information, caregivers and families can prepare for increasing care needed at home and can mobilize necessary resources. Exploration of patient and caregiver spiritual, religious, and existential suffering is certainly best left to specialist palliative care teams into which chaplaincy is well integrated. Specialist palliative care may be required when the distress of caregiver becomes more complex, including complicated bereavement.

By understanding the goals and values of patients with HF and their caregivers, HF clinicians with primary palliative care training can coordinate care in line with patients’ preferences. Furthermore, for those patients with clear goals focused on comfort, a social worker could arrange for hospice care either in the home or in a facility. a referral to a social worker.

Case Examples of Primary Palliative Care

The following cases highlight the ways that the HF team is able to provide primary palliative care in terms of treating symptoms, exploring goals and values, and helping make decisions that align with the patient’s overall desired care.

Case 1: Exploration of Goals and Values and Initiating Caregiver Support

Mr. S is a 67-year-old man with ischemic cardiomyopathy and type II diabetes who has been followed by a HF cardiologist, Dr. M, for several years. He has been married for over 40 years and lives with his wife. He has adult children who live out of state. Over the past 6 months his HF has progressed from stable NYHA class II symptoms to class IV symptoms. Despite the addition of cardiac resynchronization therapy and maximizing oral HF therapies, he continued to decline and was admitted for volume overload. He was started on a continuous milrinone infusion with improvement of symptoms and was sent home on that therapy. Dr. M referred him for evaluation for both heart transplant and mechanical circulatory support and he was deemed ineligible for both due to morbid obesity, history of two prior bypass surgeries and significant chronic kidney disease. Dr. M met with Mr. S and his wife during a follow up visit and relayed that he was ineligible for advanced therapies, including heart transplant and discussed prognosis on destination milrinone. Mr. S’s wife shared her difficulties in caring for Mr. S at home with the intravenous medication. She shared that she was hoping it would be temporary until he could receive a transplant. Learning their current situation would continue indefinitely was a shock to her. She asked if there was a way for her to have more help caring for him at home. Dr. M offered to have the social worker from the HF program speak to Mr. S and his wife to investigate how they might add more supports at home. She also explained increased risk of sudden cardiac death on continuous milrinone and explored his goals and values. She learned that Mr. S was feeling better on his current therapy and would be willing to continue on the milrinone for as long as it would be helpful but would like his death to be peaceful and does not want to a lot of time in the hospital or be a burden on his family. In accordance with Mr. S’ wishes, the milrinone was continued and Dr. S recommended deactivation of his defibrillator.

Case 2: Alignment of Patient Preferences with Medical Therapies

Ms. C is an 80-year-old woman with metastatic pancreatic cancer diagnosed during a recent hospital admission. She lives alone in an apartment with her daughter. She presented to the emergency department several days after her initial appointment with oncology with chest pain and was found to have non-specific EKG changes and elevated cardiac enzymes. She was admitted to the cardiology service and a stress echo showed reversible ischemia. Ms. C was referred for cardiac catheterization. In light of her diagnosis of advanced cancer, the interventional cardiologist, Dr. G initiated a code status conversation with the patient and her daughter prior to the procedure and learned that Ms. C did not want to undergo CPR under any circumstances and had actually decided during her oncology evaluation not to pursue chemotherapy. Dr. G suggested that she forego catheterization and treat her anginal symptoms medically. He discussed the option of hospice referral with Ms. C and her daughter and they were in agreement that hospice would be helpful in managing her symptoms and supporting her family. Dr. G asked the nurse case manager on the cardiology floor to place a referral for home hospice.

Models for Primary Palliative Care Training

Because the distinction of primary palliative care and specialist palliative care is new to the field of palliative medicine, many of the features are still being defined. Nevertheless, there are primary palliative care training models available with a focus to educate physicians, physician assistants, nurses, case managers and social workers who care for patients across all diagnoses (Table 2). Specifically, the Center to Advance Palliative Care (CAPC) has developed a web-based clinical skills curriculum, with a focus on pain management, communication skills, symptom management and training in whole patient care. These online modules (www.capc.org) offer clinical training for clinicians from all disciplines and specialties who care for patients with serious illness. In addition, the Education in Palliative and End-of-life Care (EPEC) Program, which began in 1997, has developed curriculum to educate healthcare professionals of all backgrounds in the essential clinical competencies of palliative and end-of-life care with the goal to ensure all patients receive the primary palliative care they need (http://bioethics.northwestern.edu/programs/epec/). The EPEC curriculum combines didactic sessions, video presentations, interactive discussions, and practice exercises. It teaches fundamental palliative care skills in communication, ethical decision making, psychosocial considerations, and symptom management. There are also specialized EPEC programs for professionals in emergency medicine, oncology, and pediatrics and those who care for veterans as well as a program for caregivers. These courses offer both in-person conferences and workshops, as well as distance learning with online modules.

Another resource for primary palliative care training is The End-of-Life Nursing Education Consortium (ELNEC) project,^70–73 a national education initiative to improve palliative care by training nursing faculty in palliative care so they can teach this essential information to nursing students and practicing nurses (http://www.aacn.nche.edu/elnec). In addition to ELNEC-Core, which is appropriate for all nurses, there are specialty ELNEC courses for advanced practice RNs, as well as specialty nurses in pediatrics, oncology, critical care and geriatrics. Currently, a cardiac specific training is being developed. While there is not a primary palliative care training curriculum tailored to HF clinicians, there are models under development to address this growing need.

Kavalieratos and colleagues are developing a primary palliative care intervention for patients with NYHA Class III–IV HF being cared for in community-based outpatient cardiology clinics. This intervention is informed by the Chronic Care Model,⁵⁵ a well-established model of disease management that is commonly utilized in cardiology, to concomitantly provide primary palliative care early within patients’ usual outpatient, community HF care experiences. Indeed, multiple aspects of palliative care (e.g., care coordination, decision support) align with principles of disease management, as conceptualized by the Chronic Care Model. After receiving a two-day training in core palliative care topics, an existing cardiology nurse will deliver a manualized intervention to patients during regularly scheduled outpatient cardiology office visits; additional telephone contacts will serve to reinforce content. The intervention will span five domains: symptom management, psychosocial support, advance care planning (e.g., understanding prognosis and electing a proxy), care coordination and self-management. With funding from the National Heart, Lung, and Blood Institute, this intervention⁷⁴ will undergo pilot testing to establish its feasibility and acceptability; future research will compare the effectiveness of this intervention against usual care.

CardioTALK Communication Skills Training

Another model specifically for development of communication skill training for cardiology physicians is Cardiotalk⁷⁵, which is based on VitalTalk (vitaltalk.org) (originally Oncotalk), a communication skills training program which has demonstrated effectiveness with an increase in a mean of 5.5 new communication skills per participant.^76–78 This communication training consists of brief didactic sessions, practice sessions using new skills, and reflection on skills used.⁷⁶ By building off the experiential learning model⁷⁹ and deliberate practice,⁸⁰ learners improve their ability to respond to emotion, elicit patient goals and values thereby create a more patient-centered encounter.⁷⁶

Cardiotalk has been part of fellow and attending physician education at a large academic medical center since 2014. Cardiology fellows and attending faculty were surveyed prior to the workshop on their level of prior education in communication as well as their willingness to participate. All of the fellows reported having received at least some education in communication while close to sixty percent of the faculty reported having some prior education. Given this information, many cardiologists may have a basic framework for communication but may still benefit from additional communication training. In the group surveyed, providers welcomed the opportunity to improve basic communication skills.

Additional data examining participant level of perceived preparedness collected after the workshop demonstrated that cardiology fellows and faculty reported feeling more prepared to perform basic communication skills after the training. These skills included giving bad news, conducting family conferences, defining goals of care, expressing empathy, responding to emotion, discussing code status, respecting and supporting religious and spiritual beliefs and withdrawing life sustain therapies.

Future Directions

Unfortunately, the limited number of clinical models in HF has not been well tested, and even those that have demonstrated effectiveness and improvements in patient care have not been able to demonstrate exactly which of the elements of palliative care are directly related to better outcomes.⁸¹ A more nuanced understanding of the impact of different aspects of palliative care is required to export these models to other settings where the entire breadth of palliative care expertise may not be readily available.

In order to meet the growing need for palliative care for patients with advanced HF, funding is needed to develop optimal models of primary and specialist palliative care. Unfortunately, in spite of multiple guidelines advocating palliative care for patients with advanced HF, the NIH funding support for HF research related to palliative care is lacking. A recent review of published literature, HF-related conference proceedings and NIH funding from 2009 to 2013 found that of the journals reviewed, less than 1% of their publications related to palliative care. Less than 2% of HF-related sessions in conference proceedings mentioned palliative care. Of the NIH’s $45 billion directed to HF research, only $14 million (0.03%) was spent on palliative care research.⁸²

In order to meet the growing palliative care needs of patients with HF and their caregivers, dedicated funding is required to ensure high quality research examines the optimal models for providing primary palliative care to this population. In addition, further collaboration between palliative care and HF societies is necessary.

Conclusion

Palliative care is a critical addition to the care of patients with HF and their families, yet the resources to provide specialist palliative care to the vast number of patients living with HF and their families is not feasible due to the limited resource allocation and workforce of palliative care clinicians. Primary palliative care training for clinicians caring for patients with HF offers an opportunity to fill this gap and ensure that these patients are receiving both the highest quality of care across the spectrum of their serious illness, from diagnosis to death. In spite of the vast needs, there is little data to support primary palliative care models for this population; therefore, research is needed to advance this nascent field. Fortunately, with the increasing demand for palliative care in this population from clinicians, specialty societies and regulatory bodies, including CMS, there are growing opportunities to develop successful models for primary palliative care in this population, and to better clarify the role of specialist palliative care for the most complex needs of this population.
