Palliative care should be integrated into routine disease management for all patients with serious illness, regardless of settings or prognosis. The purposes of this integrative review were to identify the features of randomized controlled trials for adult patients with heart failure and to provide basic references for the development of future trials. Using Whittemore and Knafl's integrative literature review method, comprehensive searches of the PubMed, Cochrane Library, CINAHL, EMBASE, and Korean databases were conducted, integrating keywords about heart failure and palliative care interventions. Quality appraisal was assessed using Cochrane risk-of-bias tools. In total, there were 6 trials providing palliative care interventions integrating team-based approaches between palliative care specialists and nonpalliative clinicians, such as a cardiologist, cardiac nurse, and advanced practice nurse across inpatient and outpatient settings. The different types of interventions included home visits, symptom management via phone calls or referral to a specialist team, and the establishment of treatment planning. Patient-reported outcome measures included positive effects of palliative interventions on symptom burden and quality of life. Given that most of the selected studies were conducted in Western countries, palliative care should be culturally tailored to assist heart failure patients worldwide.
KEY WORDSadvance care planning, chronic disease, heart failure, palliative care, review T he prevalence of heart failure (HF) continues to increase with an increase in the aging population. 1 The American Heart Association has reported that 50% of patients diagnosed as having HF die within 5 years, and 5% are at the end of life with a condition refractory to medical treatment. 1 Patients with HF have a significant burden of symptom clusters, including pain, fatigue, dyspnea, depression, anxiety, insomnia, and loss of appetite, causing deterioration in overall quality of life. 2 This imposes an economic and structural burden on patients and their families, as well as the social health care delivery system caring for them. 3 The treatment and management of patients with HF require the consideration of combined physical, psychosocial, and environmental factors. 4 For instance, medical devices such as pacemakers and implantable defibrillators may be effective in the early stages of HF, but their benefits may gradually wane as the disease progresses. In addition to the unpredictable prognosis, patients vary in their illness experience and perception toward overall disease management. 5 As HF progresses, responsibility for end-of-life treatment decisions may change according to the patients' or their family's cultural norms and social context. 6 The National Consensus Project Clinical Practice Guidelines for Quality Palliative Care (NCP guidelines) defines palliative care (PC) as an interdisciplinary care delivery system designed to anticipate, prevent, and manage severe illness to optimize the quality of life for patients, the...
