Instability in End-of-Life Care Preference Among Heart Failure Patients: Secondary Analysis of a Randomized Controlled Trial in Singapore

Reimagining and rebranding advance care planning

Advance care planning (ACP) has traditionally aimed at ensuring that patients' end-of-life (EOL) wishes are understood and respected. However, recent literature raises concerns about its effectiveness, with many trials indicating that ACP does not significantly improve goal-concordant care, enhance quality of life or reduce healthcare costs. This is because patients' future decisions are influenced by their transient preferences due to projection bias. To remain relevant, ACP requires a radical shift in perspective, implementation and branding. First, ACP's mission must be redefined with a focus on: Educate, Share and Prepare. This perspective emphasises ongoing conversations about patient health and illness, sharing of patients' current values and goals of care and preparation for the future, rather than making definitive future decisions. Second, ACP should be integrated into routine care, normalising these discussions. Simplifying ACP processes and shifting incentives to support shared responsibility among stakeholders can enhance integration. Last, rebranding ACP as 'Advance Care Preparation' can clarify its purpose, distinguishing it from EOL planning and increasing its uptake. This rebranding ensures that ACP meets the evolving needs of patients and their families, ultimately enhancing the quality of care and patient satisfaction. These changes in perspective, implementation and branding can transform ACP into a valuable tool for delivering compassionate, patient-centred healthcare, making it relevant to all individuals.

Prognostic understanding among advanced heart failure patients and their caregivers: A longitudinal dyadic study

OBJECTIVES

To examine heart failure patients' and caregivers' prognostic understanding (PU) over time, and patient and caregiver factors associated with their own and each other's PU.

METHODS

We used longitudinal dyadic data from Singapore, involving surveys with 95 heart failure patient-caregiver dyads every 4 months for up to 4 years. We assessed the association of PU with patient health status, caregiver psychological distress and caregiving hours using random effects multinomial logistic models, controlling for patient and caregiver characteristics.

RESULTS

At baseline, half of patients and caregivers reported correct PU. Patient and caregiver variables were associated with their own and each other's PU. Patients with poorer functional well-being were less likely to report correct PU [Average Marginal Effects (95 % CI) 0.008 (0.002, 0.015)] versus incorrect PU. Greater caregiver psychological distress was associated with a lower likelihood of caregivers reporting a correct PU [- 0.008 (-0.014, -0.002)]. Higher caregiving hours reduced the likelihood of patients reporting correct [- 0.002 (-0.003, -0.001)] and increased the likelihood of patients reporting uncertain [0.001 (0, 0.002)] PU.

CONCLUSIONS

We found PU among patients and caregivers was influenced by their own and each other's experience. Our findings highlight the importance of ongoing communication to enhance PU of patients and caregivers.

Advance directives in the intensive care unit: An eight-year vanguard cohort study

PURPOSE

To investigate the frequency, content, and clinical translation of advance directives in intensive care units (ICUs).

MATERIAL AND METHODS

Retrospective cohort study in a Swiss tertiary ICU, including patients with advance directives treated in ICUs ≥48 h. The primary endpoint was the violation of directives. Key secondary endpoints were the directives' prevalence and their translation into clinical practice.

RESULTS

Of 5'851 patients treated ≥48 h in ICUs, 2.7 % had documented directives. Despite 92 % using templates, subjective or contradictory wording was found in 19 % and 12 %. Nine percent of directives were violated. Patients with directive violations had worse in-hospital outcomes (p = 0.012). At admission, 64 % of patients experiencing violations could not communicate, and directives were missing/unrecognized in 30 %. Mostly, directives were not followed regarding life-prolonging measures (6 %), ICU admission (5 %), and mechanical ventilation (3 %). Kaplan Meier statistics revealed a lower survival rate with directives recognized at admission (p = 0.04) and when treatment was withheld (p < 0.001).

CONCLUSIONS

Advance directives are available in a minority of ICU patients and often contain subjective/contradictory wording. Physicians respected directives in 90 % of patients, with treatment adapted following their wishes. However, violation of directives may have serious consequences with unfavorable in-hospital outcomes and decreased long-term survival with treatment adaption following directives.

Effectiveness of Dyadic Advance Care Planning: A Systematic Review and Meta-Analysis

CONTEXT

Making decisions regarding end-of-life care is particularly challenging for patients and their family caregivers. Studies have advocated that family involvement in advance care planning is important to provide goal-concordant care and to increase family caregivers' preparation for surrogate decision-making. However, there is a lack of evidence to examine the effectiveness of advance care planning using the patient-caregiver dyadic approach.

OBJECTIVES

To evaluate the effectiveness of dyadic advance care planning.

METHODS

A literature search was systematically carried out in 7 databases from inception to March 2023. All randomized controlled trials with advance care planning interventions for mentally competent adults and their family caregivers were included. Meta-analysis was conducted for available quantitative data related to end-of-life care; Otherwise, narrative syntheses were performed.

RESULTS

In total, 14 randomized controlled trials were included. The main contents of all interventions were summarized into five categories, namely sharing illness experience and perception, introducing knowledge about advance care planning and end-of-life care, discussing individual's/dyads' values, goals, and care preferences, addressing dyads' discordance, and providing supports to complete advance care planning behaviors. The meta-analysis showed that dyadic advance care planning had significant effects on advance directive documentation (OR = 7.58, 95% CI [1.41, 40.63], P = 0.02) and proactive communication with doctors (OR = 2.42, 95% CI [1.42, 4.12], P = 0.001). In addition, interventions may improve dyad's congruence on end-of-life care, family caregivers' confidence in surrogate decision-making, and quality of end-of-life communication.

CONCLUSIONS

This review supports that dyadic advance care planning is a promising approach to preparing patients and their family caregivers for end-of-life communication and decision-making. Given that this multifaceted process is influenced by multiple factors within the socio-cultural context, future studies are warranted to identify the barriers and facilitators to implement dyadic advance care planning in real-world settings.

Advance Care Planning Affects End-of-Life Treatment Preferences Among Patients With Heart Failure: A Randomized Controlled Trial

This study explored the effects of advance care planning interventions on end-of-life treatment decisions among patients with heart failure. The study design was a randomized controlled trial. An intervention involving a motivational video, a cartoon version educational brochure, and a guided discussion was implemented. A total of 82 hospitalized patients with heart failure were recruited. Half of the participants received the intervention, and the other half received routine care. The Life Support Preferences Questionnaire was the primary measurement instrument. Before the advance care planning intervention, a significant difference between the experimental and control groups was observed in the cardiopulmonary resuscitation score but not the total, antibiotics, surgery, and artificial nutrition and hydration scores. In the experimental group but not in the control group, significant differences were observed between pretest and posttest total, antibiotics, cardiopulmonary resuscitation, surgery, and artificial nutrition and hydration scores. Significant differences in mean score changes were observed in total and each treatment score between the experimental and control groups. The advance care planning intervention led participants to select fewer medical treatments. This intervention may be suitable for societies where people are unfamiliar with advance care planning and may feel uncomfortable discussing death.

Advance care planning and caregiver outcomes: intervention efficacy - systematic review

CONTEXT

Caregivers make difficult end-of-life (EOL) decisions for patients, often adversely affecting their own psychological health. Understanding whether advance care planning (ACP) interventions benefit caregivers can enable healthcare systems to use these approaches to better support them.

OBJECTIVE

We conducted a systematic review and meta-analysis to identify and quantify the impacts of ACP interventions on caregiver outcomes.

METHODS

We searched MEDLINE, Embase and Cochrane databases for English-language randomised or cluster randomised controlled trials (RCTs) published until May 2021. Two reviewers independently assessed methodological quality using the Physiotherapy Evidence-Based Database Scale. We conducted a narrative synthesis for each outcome. Difference between arms with a p value of <0.05 was considered statistically significant.

RESULTS

Of the 3487 titles reviewed, 35 RCTs met eligibility; 68.6% were rated high quality. Included RCTs were heterogeneous in intervention characteristics, setting and disease. Meta-analysis of 17 RCTs showed that ACP had large and significant improvement in congruence in EOL care preferences between caregivers and patients (standardised mean difference 0.73, 95% CI 0.42 to 1.05). The effect of ACP on this outcome, however, declined over time. We also found some evidence that ACP improved bereavement outcomes (three of four RCTs), satisfaction with care quality/communication (four of the six RCTs), reduced decisional conflict (two of the two RCTs) and burden (one RCT). No study showed that mental health of caregivers were adversely affected.

CONCLUSION

The review provides most comprehensive evidence about the efficacy of ACP on caregiver outcomes. Findings suggest some evidence of benefit of ACP on caregiver outcomes.

Factors related to advance directives completion among cancer patients: a systematic review

INTRODUCTION

Advance directives (ADs) has recently been considered as an important component of palliative care for patients with advanced cancer and is a legally binding directive regarding a person's future medical care. It is used when a person is unable to participate in the decision-making process about their own care. Therefore, the present systematic review investigated the factors related to ADs from the perspective of cancer patients.

METHODS

A systematic review study was searched in four scientific databases: PubMed, Medline, Scopus, Web of Science, and ProQuest using with related keywords and without date restrictions. The quality of the studies was assessed using the Hawker criterion. The research papers were analyzed as directed content analysis based on the theory of planned behavior.

RESULTS

Out of 5900 research papers found, 22 were included in the study. The perspectives of 9061 cancer patients were investigated, of whom 4347 were men and 4714 were women. The mean ± SD of the patients' age was 62.04 ± 6.44. According to TPB, factors affecting ADs were categorized into four categories, including attitude, subjective norm, perceived behavioral control, and external factors affecting the model. The attitude category includes two subcategories: "Lack of knowledge of the ADs concept" and "Previous experience of the disease", the subjective norm category includes three subcategories: "Social support and interaction with family", "Respecting the patient's wishes" and "EOL care choices". Also, the category of perceived control behavior was categorized into two sub-categories: "Decision-making" and "Access to the healthcare system", as well as external factors affecting the model, including "socio-demographic characteristics".

CONCLUSION

The studies indicate that attention to EOL care and the wishes of patients regarding receiving medical care and preservation of human dignity, the importance of facilitating open communication between patients and their families, and different perspectives on providing information, communicating bad news and making decisions require culturally sensitive approaches. Finally, the training of cancer care professionals in the palliative care practice, promoting the participation of health care professionals in ADs activities and creating an AD-positive attitude should be strongly encouraged.

A Longitudinal Evaluation of the Preferences of Patients With Advanced Cancer for Quality of Life and Survival in Malaysia: A Discrete Choice Experiment

OBJECTIVES

This study aims to quantify the preferences of patients with advanced cancer for quality of life (QoL) outcomes versus survival extension in Malaysia. The secondary aim of this study is to explore the change in preferences over time.

METHODS

A discrete choice experiment was developed to include 7 attributes valued in cancer management: physical, psychological and social functioning, pain control, survival, place of death, and cost. Patients were recruited via convenience sampling from 2 Malaysian public hospitals. The survey questionnaire was administered to patients within 6 months of their cancer diagnosis with a follow-up 3 months later. Conditional logit regression was used to estimate the preference weight, relative attribute importance, and willingness to pay.

RESULTS

One hundred valid responses were collected at baseline and 45 at follow-up. Respondents placed higher values on QoL improvements from severe to moderate or mild levels and to achieve home death over survival extension from 6 to 18 months. However, additional improvements (from moderate to mild) in some of the QoL outcomes were not valued as highly as life extension from 12 to 18 months, showing that it was vital for patients to avoid being in "severe" health dysfunction. Improving physical dysfunction from severe to mild yielded 3 times as much value as additional 1-year survival. After 3 months, the respondents' preferences changed significantly, with increased relative attribute importance of physical functioning, pain control, and cost.

CONCLUSIONS

As QoL outcomes are valued more than survival, palliative care should be introduced as early as possible to alleviate suffering related to advanced cancer.

Caregivers' End-of-Life Care Goals for Persons with Severe Dementia Change Over Time

BACKGROUND

Family caregivers make end-of-life (EOL) decisions for persons with severe dementia (PWSDs). It is not known whether the family caregivers' goals change over time.

OBJECTIVE

Assess caregivers' EOL care goal for PWSDs and change in these goals over time.

METHODS

Using a prospective cohort of 215 caregivers of PWSDs, we assessed the proportion of caregivers whose EOL care goal for PWSDs changed between two consecutive time points. Mixed effects multinomial regression models assessed factors associated with caregivers' EOL care goals for PWSD (maximal, moderate, minimal life extension); and change in EOL care goal from previous time point.

RESULTS

At baseline, 20% of the caregivers had a goal of maximal life extension for their PWSD, and 59% changed their EOL care goal at least once over a period of 16 months. Caregivers of PWSDs with lower quality of life (RR: 1.15, CI: 1.06, 1.24), who expected shorter life expectancy for PWSDs (RR: 10.34, CI: 2.14, 49.99) and who had an advance care planning discussion (RR: 3.52, CI: 1.11, 11.18) were more likely to have a goal of minimal life extension for PWSD. Caregivers with higher anticipatory grief (RR: 0.96, CI: 0.93,1) were more likely to have a goal of maximal life extension. Change in PWSDs' quality of life and change in caregivers' anticipatory grief were associated with change in caregivers' EOL care goals.

CONCLUSION

Caregivers' EOL care goals for PWSDs change over time with change in PWSD and caregiver related factors. Findings have implications regarding how health care providers can engage with caregivers.

A systematic review defining non-beneficial and inappropriate end-of-life treatment in patients with non-cancer diagnoses: theoretical development for multi-stakeholder intervention design in acute care settings

Background

Non-beneficial treatment is closely tied to inappropriate treatment at the end-of-life. Understanding the interplay between how and why these situations arise in acute care settings according to the various stakeholders is pivotal to informing decision-making and best practice at end-of-life.

Aim

To define and understand determinants of  non-beneficial and inappropriate treatments for patients with a non-cancer diagnosis, in acute care settings at the end-of-life.

Design

Systematic review of peer-reviewed studies focusing on the above and conducted in upper-middle- and high-income countries. A narrative synthesis was undertaken, guided by Realist principles.

Data sources

Cochrane; PubMed; Scopus; Embase; CINAHL; and Web of Science.

Results

Sixty-six studies (32 qualitative, 28 quantitative, and 6 mixed-methods) were included after screening 4,754 papers. Non-beneficial treatment was largely defined as when the burden of treatment outweighs any benefit to the patient. Inappropriate treatment at the end-of-life was similar to this, but additionally accounted for patient and family preferences.

Contexts in which outcomes related to non-beneficial treatment and/or inappropriate treatment occurred were described as veiled by uncertainty, driven by organizational culture, and limited by profiles and characteristics of involved stakeholders. Mechanisms relating to ‘Motivation to Address Conflict & Seek Agreement’ helped to lessen uncertainty around decision-making. Establishing agreement was reliant on ‘Valuing Clear Communication and Sharing of Information’. Reaching consensus was dependent on ‘Choices around Timing & Documenting of end-of-life Decisions’.

Conclusion

A framework mapping determinants of non-beneficial and inappropriate end-of-life treatment is developed and proposed to be potentially transferable to diverse contexts. Future studies should test and update the framework as an implementation tool.

Complexity of implementing a nationwide advance care planning program: results from a qualitative evaluation

BACKGROUND

We evaluated Singapore's national advance care planning (ACP) program to understand challenges to its implementation within multiple clinical settings.

METHODS

We conducted focus group discussions (FGDs) with a purposive sample of health care professionals (HCPs) involved in ACP program delivery within acute care hospitals, primary care clinics and nursing homes. FGDs were stratified into three categories based on HCPs' role within the ACP framework-leaders versus facilitators and advocates versus nursing home heads. Using NVivo 11, we analysed data using thematic analysis and Conceptual Framework for Implementation Research.

RESULTS

A total of 107 HCPs from 25 organisations participated in 22 FGDs. Findings revealed wide variation in ACP implementation among organisations and identified 12 themes organized within four domains-outer setting (lack of public awareness, shortcomings in inter-organisational partnerships, performance driven policies), inner setting (lack of commitment from organisational leadership, paucity of dedicated resources, absence of an institution-wide ACP culture, lack of physician engagement), characteristics of HCPs (language barriers) and process (inadequate training, complexity of conversations and documentations, challenges to retrieving ACP documents, absence of comprehensive monitoring and evaluation).

CONCLUSION

ACP program implementation is complex and faces multiple health care system challenges. To integrate ACP within routine clinical care, ACP processes should be simplified, training framework be strengthened, physicians be engaged and an ACP supportive culture be created within and outside organisations. Findings will be used to guide ACP implementation within the country and globally.

What is the evidence for efficacy of advance care planning in improving patient outcomes? A systematic review of randomised controlled trials

Objectives

To conduct an up-to-date systematic review of all randomised controlled trials assessing efficacy of advance care planning (ACP) in improving patient outcomes, healthcare use/costs and documentation.

Design

Narrative synthesis conducted for randomised controlled trials. We searched electronic databases (MEDLINE/PubMed, Embase and Cochrane databases) for English-language randomised or cluster randomised controlled trials on 11 May 2020 and updated it on 12 May 2021 using the same search strategy. Two reviewers independently extracted data and assessed methodological quality. Disagreements were resolved by consensus or a third reviewer.

Results

We reviewed 132 eligible trials published between 1992 and May 2021; 64% were high-quality. We categorised study outcomes as patient (distal and proximal), healthcare use and process outcomes. There was mixed evidence that ACP interventions improved distal patient outcomes including end-of-life care consistent with preferences (25%; 3/12 with improvement), quality of life (0/14 studies), mental health (21%; 4/19) and home deaths (25%; 1/4), or that it reduced healthcare use/costs (18%; 4/22 studies). However, we found more consistent evidence that ACP interventions improve proximal patient outcomes including quality of patient–physician communication (68%; 13/19), preference for comfort care (70%; 16/23), decisional conflict (64%; 9/14) and patient-caregiver congruence in preference (82%; 18/22) and that it improved ACP documentation (a process outcome; 63%; 34/54).

Conclusion

This review provides the most comprehensive evidence to date regarding the efficacy of ACP on key patient outcomes and healthcare use/costs. Findings suggest a need to rethink the main purpose and outcomes of ACP.

A Prospective Cohort Study of Stability in Preferred Place of Death Among Patients With Stage IV Cancer in Singapore

BACKGROUND

Advance care planning (ACP) involves documentation of patients' preferred place of death (PoD). This assumes that patients' preferred PoD will not change over time; yet, evidence for this is inconclusive. We aimed to assess the extent and correlates of change in patients' preferred PoD over time.

MATERIALS AND METHODS

Using data from a cohort study of patients with advanced cancer in Singapore, we analyzed preferred PoD (home vs institution including hospital, hospice, and nursing home vs unclear) among 466 patients every 6 months for a period of 2 years. At each time point, we assessed the proportion of patients who changed their preferred PoD from the previous time point. Using a multinomial logistic regression model, we assessed patient factors (demographics, understanding of disease stage, ACP, recent hospitalization, quality of life, symptom burden, psychologic distress, financial difficulty, prognosis) associated with change in their preferred PoD.

RESULTS

More than 25% of patients changed their preferred PoD every 6 months, with no clear trend in change toward home or institution. Patients psychologically distressed at the time of the survey had increased likelihood of changing their preferred PoD to home (relative risk ratio [RRR], 1.02; 95% CI, 1.00-1.05) and to an institution (RRR, 1.06; 95% CI, 1.02-1.10) relative to no change in preference. Patients hospitalized in the past 6 months were more likely to change their preferred PoD to home (RRR, 1.56; 95% CI, 1.07-2.29) and less likely to change to an institution (RRR, 0.50; 95% CI, 0.28-0.88) relative to no change in preference.

CONCLUSIONS

The present study provides evidence of instability in the preferred PoD of patients with advanced cancer. ACP documents need to be updated regularly to ensure they accurately reflect patients' current preference.

Instability in Preference for Place of Death Among Patients With Symptoms of Advanced Heart Failure

OBJECTIVES

Patient preference for place of death is an important component of advance care planning (ACP). If patients' preference for place of death changes over time, this questions the value of their documented preference. We aimed to assess the extent and correlates of change in preference for place of death over time among patients with symptoms of advanced heart failure.

DESIGN

We conducted a secondary analysis of data from a randomized controlled trial of a formal ACP program vs usual care.

SETTING AND PARTICIPANTS

We interviewed 282 patients aged 21 years old and above with heart failure and New York Heart Association Classification III and IV symptoms in Singapore. Analytic sample included 200 patients interviewed at least twice.

METHODS

We assessed factors associated with patients' preference for place of death (home/institution/no preference) and change in their preference for place of death from previous time point (change toward home death/toward an institutional death/toward no preference/no change). These included patient demographics, quality of life (Kansas City Cardiomyopathy Questionnaire), and prognostic understanding.

RESULTS

In our study, 66% of patients with heart failure changed their preference for place of death at least once during the study period with no consistent pattern of change. Correct prognostic understanding at the time of survey reduced the relative risk of change in preference for place of death to home (relative risk ratio 0.49, 95% confidence interval 0.32, 0.76), whereas a higher quality of life score was associated with a lower relative risk of patients changing their preferred place of death to an institution (relative risk ratio 0.99, 95% confidence interval 0.97, 1.00) relative to no change in preference.

CONCLUSIONS AND IMPLICATIONS

We provide evidence of instability in patients with heart failure preference for place of death, which suggests that ACP documents should be regularly re-evaluated.
