Palliative Care for Patients With Advanced Heart Disease

Palliative Care Utilization in Patients Requiring Extracorporeal Membrane Oxygenation: An Observational Study

Palliative care (PC) is a model of care centered around improving the quality of life for individuals with life-limiting illnesses. Few studies have examined its impact in patients on extracorporeal membrane oxygenation (ECMO). We aimed to describe demographics, clinical characteristics, and complications associated with PC consultation in adult patients requiring ECMO support. We analyzed data from an ECMO registry, including patients aged 18 years and older who have received either venoarterial (VA)- or venovenous (VV)-ECMO support between July 2016 and September 2021. We used analysis of variance and Fisher exact tests to identify factors associated with PC consultation. Of 256, 177 patients (69.1%) received VA-ECMO support and 79 (30.9%) received VV-ECMO support. Overall, 115 patients (44.9%) received PC consultation while on ECMO. Patients receiving PC consultation were more likely to be non-white (47% vs. 53%, p = 0.016), have an attending physician from a medical versus surgical specialty (65.3% vs. 39.6%), have VV-ECMO (77.2% vs. 30.5%, p < 0.001), and have longer ECMO duration (6.2 vs. 23.0, p < 0.001). Patients were seen by the PC team on an average of 7.6 times (range, 1-35), with those who died having significantly more visits (11.2 vs. 5.6, p < 0.001) despite the shorter hospital stay. The average time from cannulation to the first PC visit was 5.3 ± 5 days. Congestive heart failure in VA-ECMO, coronavirus disease 2019 infection in VV-ECMO, and non-white race and longer ECMO duration for all patients were associated with PC consultation. We found that despite the benefits of PC, it is underused in this population.

Palliative Care Use in Patients With Acute Myocardial Infarction and Do-Not-Resuscitate Status From a Nationwide Inpatient Cohort

OBJECTIVE

To examine the predictors, treatments, and outcomes of the use of palliative care in patients hospitalized with acute myocardial infarction (AMI) who had a do-not-resuscitate (DNR) order.

PATIENTS AND METHODS

Using the National (Nationwide) Inpatient Sampling database for 2015-2018, we examined the predictors, in-hospital procedures, and outcomes of palliative care recipients among patients with AMI who had a DNR order.

RESULTS

We identified 339,270 admissions with AMI that had a DNR order, including patients who received palliative care (n=113,215 [33.4%]). Compared with patients who did not receive palliative care, these patients were more frequently younger (median age, 81 vs 83 years; P<.001), were less likely to be female (50.9% [57,626 of 113,215] vs 54.7% [123,652 of 226,055]; P<.001), and were more likely to present with cardiac arrest (11.6% [13,133 of 113,215] vs 6.9% [15,598 of 226,055]; P<.001). Patients were more likely to receive palliative care at a large (odds ratio [OR], 1.47; 95% CI, 1.44 to 1.50) or teaching (OR, 2.10; 95% CI, 2.04 to 2.16) hospitals compared with small or rural ones. Patients receiving palliative care were less likely to be treated invasively, with reduced rates of invasive coronary angiography (OR, 0.46; 95% CI, 0.45 to 0.47) and percutaneous coronary intervention (OR, 0.47; 95% CI, 0.45 to 0.48), and were more likely to die in the hospital (52.4% [59,325 of 113,215] vs 22.9% [51,766 of 226,055]).

CONCLUSION

In patients who had a DNR status and were hospitalized and received a diagnosis of AMI, only one-third received palliative care.

Criteria for Referral of Patients With Advanced Heart Failure for Specialized Palliative Care

BACKGROUND

Patients with advanced heart failure have substantial supportive care needs. Specialist palliative care can be beneficial, but it is unclear who is most appropriate for referral and when patients should be referred.

OBJECTIVES

We conducted a Delphi study of international experts to identify consensus referral criteria for specialist palliative care for patients with advanced heart failure.

METHODS

Clinicians from 5 continents with expertise in the integration of cardiology and palliative care were asked to rate 34 disease-based, 24 needs-based, and 9 time-based criteria over 3 rounds. Consensus was defined a priori as ≥70% agreement. A criterion was coded as major if the experts endorsed that meeting that criterion alone was adequate to justify a referral.

RESULTS

The response rate was 44 of 46 (96%), 41 of 46 (89%), and 43 of 46 (93%) in the first, second, and third rounds, respectively. Panelists reached consensus on 25 major criteria for specialist palliative care referral. The 25 major criteria were categorized under 6 topics, including "advanced/refractory heart failure, comorbidities, and complications" (eg, cardiac cachexia, cardiorenal syndrome) (n = 8), "advanced heart failure therapies" (eg, chronic inotropes, precardiac transplant) (n = 4), "hospital utilization" (eg, emergency room visits, hospitalization) (n = 2), "prognostic estimate" (n = 1), "symptom burden/distress" (eg, severe physical/emotional/spiritual distress) (n = 6), and "decision making/social support" (eg, goals-of-care discussions) (n = 4). The majority (68%) of major criteria had ≥90% agreement.

CONCLUSIONS

International experts reached consensus on a large number of criteria for referral to specialist palliative care. With further validation, these criteria may be useful for standardizing palliative care access in the inpatient and/or outpatient settings.

Strategies for knowledge translation of a palliative approach outside specialized palliative care services: a scoping review

Objectives

Research suggests palliative care to be translated and integrated in non-specialized palliative care services throughout the palliative care continuum across populations and settings. A need has been identified to build on the existing research literature in order to design strong knowledge translation strategies that can be evaluated in future research. The aim was to map strategies for knowledge translation of a palliative approach to care into non-specialized palliative care services for adult patients. The objectives were to explore the primary research activities, the specific type of knowledge translation strategies used, the research designs and study settings for such evaluations along with the major results thereof, and to identify major research gaps in this area.

Methods

A scoping review was performed to map the volume and characteristics of research literature (project registered in PROSPERO #2018 CRD42018100663). The ten-year period 2010 to 2019 was searched in six major databases for original articles published in English in which the knowledge translation of a palliative approach for adult patients was evaluated in non-specialized palliative healthcare settings, and all type of empirical data-based research designs. We excluded non-English, non-empirical articles, non-evaluation of knowledge translations, specialized palliative care settings, and other types of publications (i.e. non-original articles).

Results

Most of the 183 included articles focused on patients with cancer who were dying in hospitals and in high income countries. Only 13 articles focused on early palliative care. A palette of different strategies was used to implement palliative care in non-specialist palliative settings; no strategy was identified as outstanding. The majority of the articles had unspecified essential components of the research designs.

Conclusion

Previous suggestions for utilization of implementation science for knowledge translation of a palliative approach to care into non-specialized palliative care services are confirmed, and established knowledge translation theories can strengthen the field. To advance this specific field of knowledge, meticulously detailed reporting of studies is required as related to research designs, clarifications of contextual influences and mechanisms at work. Specific systematic reviews and meta-syntheses in the field are merited.

Caring for Patients in Need of Palliative Care: Is This a Mission for Acute Care Hospitals? Key Questions for Healthcare Professionals

The prevalence of patients affected by end-stage diseases or advanced cancer is increasing due to an aging population and progression in medicine and public healthcare. The burden of symptoms these people suffer in the last months of life often forces them to seek aid in an emergency department. In developed countries, acute care hospital-based services are often better designed to treat acute clinical conditions than to manage the needs of patients with serious chronic diseases. Thus, the palliative care (PC) population poses very real clinical challenges to healthcare professionals who care for them in hospital settings. The authors have formulated four key questions (who, why, when, and how) to address in order to identify a model for providing the best care for these PC patients. The questions are related to: (1) defining people living with serious chronic diseases; (2) managing the challenge of unplanned hospital admission of these people; (3) identifying PC patients among people with serious chronic diseases; and (4) determining the appropriate work of caring for this inpatient PC population. Clinicians need the knowledge, tools, and services to care for these PC patients, and acute care hospitals should plan the work of caring for these inpatients.

Improving Dyspnoea Symptom Control of Patients in Palliative Care Using a Smart Patch-A Proof of Concept Study

The world of healthcare constantly aims to improve the lives of people while nurturing their health and comfort. Digital health and wearable technologies are aimed at making this possible. However, there are numerous factors that need to be addressed such as aging, disabilities, and health hazards. These factors are intensified in palliative care (PC) patients and limited hospital capacities make it challenging for health care providers (HCP) to handle the crisis. One of the most common symptoms reported by PC patients with severe conditions is dyspnoea. Monitoring devices with sufficient comfort could improve symptom control of patients with dyspnoea in PC. In this article, we discuss the proof-of-concept study to investigate a smart patch (SP), which monitors the pulmonary parameters: (a) breathing rate (BR) and inspiration to expiration ratio (I:E); markers for distress: (b) heart rate (HR) and heart rate variability (HRV), and (c) transmits real-time data securely to an adaptable user interface, primarily geared for palliative HCP but scalable to specific needs. The concept is verified by measuring and analyzing physiological signals from different electrode positions on the chest and comparing the results achieved with the gold standard Task Force Monitor (TFM).

Palliative Care Conversations for Heart Failure Nurses: A Pilot Education Intervention

Introduction

Heart failure is a progressive condition affecting 6.2 million Americans. The use of palliative and supportive care for symptom management and improved quality of life is recommended for persons with heart failure. However, 91% of nurses believe they need further training to have palliative care conversations. The purpose of this pilot education intervention was to determine if providing nurses with education on the timing and content of palliative care conversations would improve their perceived skill and knowledge.

Methods

This was a pilot study of an online educational intervention. Data were electronically collected from 13 participants using validated questionnaires delivered via Qualtrics. Participants completed a demographic survey and End-of-Life Professional Caregiver Survey (EPCS) before and after completing an online, asynchronous education module.

Results

Mean scores were higher on all posttest measures. Independent samples t-tests revealed statistically significant differences on the Effective Care Delivery (ECD) scale (t[32] = -2, p = .05) and total EPCS scale scores (t[32] = -2.2, p = .03) from pre- to posttest.

Conclusion

Scores increased on all dimensions pretest to posttest with statistically significant differences in ECD and total scores. Providing asynchronous online education on timing and content of palliative care conversations to nurses caring for people with heart failure is a feasible and effective way to improve perceived knowledge and skill of palliative care conversations.

Design of 1-year mortality forecast at hospital admission: A machine learning approach

Palliative care is referred to a set of programs for patients that suffer life-limiting illnesses. These programs aim to maximize the quality of life (QoL) for the last stage of life. They are currently based on clinical evaluation of the risk of 1-year mortality. The main aim of this work is to develop and validate machine-learning-based models to predict the exitus of a patient within the next year using data gathered at hospital admission. Five machine-learning techniques were applied using a retrospective dataset. The evaluation was performed with five metrics computed by a resampling strategy: Accuracy, the area under the ROC curve, Specificity, Sensitivity, and the Balanced Error Rate. All models reported an AUC ROC from 0.857 to 0.91. Specifically, Gradient Boosting Classifier was the best model, producing an AUC ROC of 0.91, a sensitivity of 0.858, a specificity of 0.808, and a BER of 0.1687. Information from standard procedures at hospital admission combined with machine learning techniques produced models with competitive discriminative power. Our models reach the best results reported in the state of the art. These results demonstrate that they can be used as an accurate data-driven palliative care criteria inclusion.

The need for palliative and support care services for heart failure patients in the community

BACKGROUND

Palliative care is a care option considered appropriate for those with heart failure, but is uncommon partially due to a lack of timely identification of those needing palliative care. A standard mechanism that triggers which heart failure patients should receive palliative care is not available. The Gold Standards Framework (GSF) identifies those needing palliative care but has not been investigated with heart failure patients.

OBJECTIVES

To describe palliative care provided in the community and determine whether the GSF can identify heart failure patients in need of palliative care.

METHODS

Descriptive study. A total of 252 heart failure patients in the community completed a demographic characteristics questionnaire, the Edmonton symptom assessment scale-revised and the Minnesota living with heart failure questionnaire. Clinical data were collected from the medical chart and the primary physician completed the GSF prognostic indicator guidance.

RESULTS

Participants had a mean age of 76.9 years (standard deviation 10.9), most at New York Heart Association level III (n=152, 60%). Fewer than half received pain medications (n=76, 30%), anxiolytics (n=35, 14%), antidepressants (n=64, 25%) or sleep medications (n=65, 26%). Eight patients spoke with a psychologist or psychologist (3%). One had an advanced directive and 16 (6%) had a record of discussions with their family caregivers. Three (1%) had end-of-life discussions with their healthcare providers. Most healthcare providers responded 'no' to the 'surprise question' (n=160, 63%). Sensitivity and specificity of the gold standards framework was poor.

CONCLUSIONS

Few community dwelling heart failure patients received most aspects of palliative care. The gold standards framework was not a good indicator of those who should receive palliative care.

Referral Criteria to Palliative Care for Patients With Heart Failure: A Systematic Review

BACKGROUND

Patients with heart failure have significant symptom burden, care needs, and often a progressive course to end-stage disease. Palliative care referrals may be helpful but it is currently unclear when patients should be referred and by whom. We conducted a systematic review of the literature to examine referral criteria for palliative care among patients with heart failure.

METHODS

We searched Ovid, MEDLINE, Ovid Embase, and PubMed databases for articles in the English language from the inception of databases to January 17, 2019 related to palliative care referral in patients with heart failure. Two investigators independently reviewed each citation for inclusion and then extracted the referral criteria. Referral criteria were then categorized thematically.

RESULTS

Of the 1199 citations in our initial search, 102 articles were included in the final sample. We identified 18 categories of referral criteria, including 7 needs-based criteria and 10 disease-based criteria. The most commonly discussed criterion was physical or emotional symptoms (n=51 [50%]), followed by cardiac stage (n=46 [45%]), hospital utilization (n=38 [37%]), prognosis (n=37 [36%]), and advanced cardiac therapies (n=36 [35%]). Under cardiac stage, 31 (30%) articles suggested New York Heart Association functional class ≥III and 12 (12%) recommended New York Heart Association class ≥IV as cutoffs for referral. Prognosis of ≤1 year was mentioned in 21 (21%) articles as a potential trigger; few other criteria had specific cutoffs.

CONCLUSIONS

This systematic review highlighted the lack of consensus regarding referral criteria for the involvement of palliative care in patients with heart failure. Further research is needed to identify appropriate and timely triggers for palliative care referral.

End-of-Life Care in Cardiothoracic Surgery

Patients undergoing cardiothoracic surgery face a small but significant mortality risk. Despite this, end-of-life care specific to this population has received little attention. This article examines current literature on end-of-life care in cardiothoracic surgery and in critical care. Recommendations for management at the end of life are made based on the available evidence.
