Breaking Barriers: Prospective Study of a Cohort of Advanced Chronic Obstructive Pulmonary Disease Patients To Describe Their Survival and End-of-Life Palliative Care Requirements

Advance care planning for patient with chronic obstructive pulmonary disease: An evolutionary concept analysis

AIM

This study aimed to analyze the concept of advance care planning (ACP) for patients with chronic obstructive pulmonary disease (COPD), by systematically clarifying the attributes, antecedents, consequences, surrogate terms, related concepts, and historical transition of the concept.

METHODS

Following Rodgers' method of concept analysis, the academic development of concepts related to ACP for patients with COPD, as well as changes in the concept over time, is comprehensively organized and described. A search formula for relevant literature was created using the two keywords "chronic obstructive pulmonary disease" and "advance care planning". The databases of CENTRAL, PubMed, CINAHL Plus with Full Text, Embase, and PsycInfo were searched without limitation by the year of publication and restricted to English and Japanese languages.

RESULTS

Of the 3433 retrieved articles, 30 peer-reviewed articles were included in the analysis. Data extraction was conducted to identify concepts relevant to ACP for patients with COPD, resulting in the identification of four antecedents (COPD progression, decline in QOL, attitude toward facing death and dying, and interdisciplinary team approach); four attributes (discussion process, documentation, support for facing death, and dying, holistic approach); and four consequences (dialogical process, improved support of decision-making, physical impacts, and psychological impacts).

CONCLUSIONS

This conceptual framework, identified through this analysis, shows an evolution from a medical perspective to encompassing humanistic perspectives in addressing patient needs and emphasizes the importance of nursing practices. The elucidated concept characteristics may enhance its application, practice promotion, and interdisciplinary understanding across healthcare professions in the end-of-life field.

Home ventilation for patients with end-stage chronic obstructive pulmonary disease

PURPOSE OF THE REVIEW

The number of patients with end-stage chronic obstructive pulmonary disease (COPD) treated with chronic non-invasive ventilation (NIV) has greatly increased. In this review, the authors summarize the evidence for nocturnal NIV and NIV during exercise. The authors discuss the multidisciplinary and advanced care of patients with end-stage COPD treated with NIV.

RECENT FINDINGS

Nocturnal NIV improves gas exchange, health-related quality of life and survival in stable hypercapnic COPD patients. Improvements in care delivery have been achieved by relocating care from the hospital to home based; home initiation of chronic NIV is feasible, non-inferior regarding efficacy and cost-effective compared to in-hospital initiation. However, the effect of NIV on symptoms is variable, and applying optimal NIV for end-stage COPD is complex. While exercise-induced dyspnoea is a prominent complaint in end-stage COPD, nocturnal NIV will not change this. However, NIV applied solely during exercise might improve exercise tolerance and dyspnoea. While chronic NIV is often a long-standing treatment, patient expectations should be discussed early and be managed continuously during the treatment. Further, integration of advance care planning requires a multidisciplinary approach.

SUMMARY

Although chronic NIV is an effective treatment in end-stage COPD with persistent hypercapnia, there are still important questions that need to be answered to improve care of these severely ill patients.

Effectiveness of the integration of a palliative care team in the follow-up of patients with advanced chronic obstructive pulmonary disease: The home obstructive lung disease study

BACKGROUND

Access to palliative care for patients with end-stage chronic obstructive pulmonary disease (COPD) is still very poor.

OBJECTIVES

Evaluate our palliative care program for patients with advanced COPD by assessing whether the referral criteria for advanced COPD patients were adequate in identifying patients in end-of-life care and determine the results of the palliative care team's intervention METHODS: This was a prospective observational study of patients admitted to a multidisciplinary unit for advanced COPD. Data on sociodemographic variables, survival, symptomatology, quality of life, ACP, and health resource utilization were analyzed.

RESULTS

Eighty-three patients were included in this study. By the end of the follow-up period, 69 (83%) patients had died, mainly due to respiratory failure (96%). The median duration of survival from the start of follow-up was 4.27 months (95% confidence interval, 1.97-16.07). Most patients (94%) had a dyspnea level of 4. Sixty (72%) patients required opioids for dyspnea control. There were no significant differences in the quality of life of the patients during follow-up. Thirty (43%) patients died at home, 26 (38%) in a palliative care unit, and 13 (19%) in an acute care hospital. ACP was performed for 50 (72%) patients. Forty (57%) patients required palliative sedation during follow-up. Dyspnea was the reason for sedation in 34 (85%) patients. Hospital admissions and emergency room visits decreased significantly (p = 0.01) during follow-up.

CONCLUSIONS

Our integrated model allows for adequate selection of patients, facilitates symptom control and ACP, reduces resource utilization, and favors death at home.

Systematic Review of Models of Effective Community Specialist Palliative Care Services for Evidence of Improved Patient-Related Outcomes, Equity, Integration, and Health Service Utilization

Background: The benefits of palliative care programs are well documented. However, the effectiveness of specialist palliative care services is not well established. The previous lack of consensus on criteria for defining and characterizing models of care has restrained direct comparison between these models and limited the evidence base to inform policy makers. A rapid review for studies published up to 2012 was unable to find an effective model. Aim: To identify effective models of community specialist palliative care services. Design: A mixed-method synthesis design reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Prospero: CRD42020151840. Data sources: Medline, PubMed, EMBASE, CINAHL and the Cochrane Database of Systematic Reviews were searched in September 2019 for primary research and review articles from 2012 to 2019. Supplementary search was conducted on Google in 2020 for policy documents to identify additional relevant studies. Results: The search yielded 2255 articles; 36 articles satisfied the eligibility criteria and 6 additional articles were identified from other sources. Eight systematic reviews and 34 primary studies were identified: observational studies (n = 24), randomized controlled trials (n = 5), and qualitative studies (n = 5). Community specialist palliative care was found to improve symptom burden/quality of life and to reduce secondary service utilization across cancer and noncancer diagnoses. Much of this evidence relates to face-to-face care in home-based settings with both round-the-clock and episodic care. There were few studies addressing pediatric populations or minority groups. Findings from qualitative studies revealed that care coordination, provision of practical help, after-hours support, and medical crisis management were some of the factors contributing to patients' and caregivers' positive experience. Conclusion: Strong evidence exists for community specialist palliative care to improve quality of life and reducing secondary service utilization. Future research should focus on equity outcomes and the interface between generalist and specialist care.

Palliative Care Interventions in Advanced Chronic Obstructive Pulmonary Disease: An Integrative Review

Background: Chronic obstructive pulmonary disease (COPD), the sixth leading cause of death in the United States, is associated with higher mortality rates in women. Women also experience tremendous symptom burden, including dyspnea, anxiety, and depression, in comparison to men with COPD. Palliative care (PC) provides symptom management and addresses advanced care planning for serious illness, but little is known about the use of PC in women with COPD. Objective: The purpose of this integrative review was to identify known PC interventions in advanced COPD and to understand the problem of gender and sex disparities. Methods: Whittemore and Knafl's methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used to guide this integrative review, and the quality of the articles was appraised using the Mixed Methods Appraisal Tool2018 version. A database search was conducted in PubMed, SCOPUS, ProQuest, and CINAHL complete between 2009 and 2021. Results: Application of search terms yielded 1005 articles. After screening 877 articles, 124 met inclusion criteria, resulting in a final sample of 15 articles. Study characteristics were evaluated for common concepts and synthesized using the Theory of Unpleasant Symptoms influencing factors (physiological, situational, and performance). All 15 studies discussed PC interventions with the focus on dyspnea management or improvement in quality of life. None of the studies identified in this review focused specifically on women with advanced COPD receiving PC, despite the significant impact that this illness has on women. Conclusion: It remains unknown if any intervention is more beneficial than another for women with advanced COPD. Future research is needed to provide an understanding of the unmet PC needs of women with advanced COPD.

Grupo de síntomas de enfermedad pulmonar obstructiva crónica y cuidados paliativos: una revisión sistemática

La enfermedad pulmonar obstructiva crónica (EPOC) es una entidad patológica que se caracteriza por una serie de manifestaciones físicas persistentes como tos, fatiga, disnea y producción de esputo; síntomas que generan malestar en el paciente desde el momento del diagnóstico y que, al ser una enfermedad irreversible por el daño tisular que causa, progresivamente va incidiendo de manera negativa en la calidad de vida. De otra parte, se ha reportado presencia de síntomas psicológicos como depresión, inseguridad, ansiedad y alteraciones emocionales en los pacientes diagnosticados con EPOC. Así mismo, los pacientes con este diagnóstico tienden a desarrollar comportamientos que alteran sus relaciones sociales familiares y laborales, por cuanto tienden a aislarse debido a la sintomatología, especialmente física. La situación planteada genera la necesidad de desarrollar un trabajo de investigación con el objetivo de reconocer el clúster de síntomas físicos, psicológicos y sociales de los pacientes diagnosticados con EPOC, e identificar si se plantea un abordaje desde la atención paliativa. El estudio se desarrolló mediante una revisión sistemática de literatura en la que se identificaron 1776 artículos, de los que se evaluaron 41 para la identificación del clúster de síntomas. Se identificó el binomio disnea y tos, fatiga y expectoración como el clúster de síntomas físicos; la depresión y la ansiedad constituyen el clúster de síntomas psicológicos, y el impacto en la calidad de vida y la percepción de aislamiento o exclusión social.

Pain and Spiritual Distress at End of Life: A Correlational Study

Objective: The purpose of this study is to examine the relationship between unmanaged pain and spiritual distress in adults newly admitted to hospice. Background: Current evidence supports the presence of a positive relationship between increased physical pain and spiritual distress for those with advanced cancer and/or receiving palliative care services. Nonetheless, spiritual distress remains a relatively understudied area; anecdotally, assessment and management of physical symptoms often take precedence over interventions for spiritual distress in patients at end of life (EOL) on hospice. Further research is needed to examine the relationships between physical pain, spiritual distress, and factors such as age, gender, and religious affiliation/spiritual practice specific to EOL patients receiving home hospice care. The Total Pain Model underpins this study. Methods: In this cross-sectional correlational study, pre-existing data were extracted from a hospice agency's electronic health record (EHR) to examine age, gender, marital status, race/ethnicity, religious affiliation and/or spiritual practice, hospice diagnosis, pain severity, and spiritual distress in adult patients (age 18 and over) admitted to home hospice services (N = 3484). Descriptive, bivariate, and multivariate analyzes were conducted. Results: The age range for this sample was 25 to 107 years old (M = 82, SD = 12.08). Over half of the sample were female and white. One third of the patients were married or had a designated life partner. Over 85% identified as either Catholic or Protestant. Sixteen percent reported moderate to severe pain and 9.6% experienced spiritual distress. Marital status (χ² (3, N = 2483) = 20.21, P < .001, Cramer's V = .09), hospice diagnosis (χ² (5, N = 3481) = 22.66, P < .001, Cramer's V = .08), pain severity (χ² (1, N = 3464) = 19.75, P < .001, Cramer's V = .08), and age (t (393.17) = 2.84, P = .005, d = .17) were significantly related to spiritual distress. The binary logistic model was statistically significant, χ² (11) = 45.25, P < .001, and cases indicating the highest odds of experiencing spiritual distress had pulmonary disease (OR = 1.8, P = .02), were single (OR = 1.6, P = .02), and had moderate to severe pain (OR = 1.4, P = .04). Conclusions: Moderate to severe pain, marital status, and diagnosis should be considered for inclusion in a refined spiritual distress hospice admission screening process. Future research should examine the unique contributions of diagnosis in predicting spiritual distress, particularly pulmonary disease.

Assessing Symptom Burden and Depression in Subjects With Chronic Respiratory Insufficiency

Objectives: Patients with chronic respiratory insufficiency suffer from advanced disease, but their overall symptom burden is poorly described. We evaluated the symptoms and screening of depression in subjects with chronic respiratory insufficiency by using the Edmonton symptom assessment system (ESAS). Methods: In this retrospective study, 226 subjects with chronic respiratory insufficiency answered the ESAS questionnaire measuring symptoms on a scale from 0 (no symptoms) to 10 (worst possible symptom), and the depression scale (DEPS) questionnaire, in which the cut-off point for depressive symptoms is 9. Results: The most severe symptoms measured with ESAS (median [interquartile range]) were shortness of breath 4.0 (1.0-7.0), dry mouth 3.0 (1.0-7.0), tiredness 3.0 (1.0-6.0), and pain on movement 3.0 (0.0-6.0). Subjects with a chronic obstructive pulmonary disease as a cause for chronic respiratory insufficiency had significantly higher scores for shortness of breath, dry mouth, and loss of appetite compared to others. Subjects with DEPS ≥9 reported significantly higher symptom scores in all ESAS categories than subjects with DEPS <9. The area under the receiver operating characteristic curve for ESAS depression score predicting DEPS ≥9 was 0.840 (P < .001). If the ESAS depression score was 0, there was an 89% probability of the DEPS being <9, and if the ESAS depression score was ≥4, there was an 89% probability of the DEPS being ≥9. The relation between ESAS depression score and DEPS was independent of subjects' characteristics and other ESAS items. Conclusions: Subjects with chronic respiratory insufficiency suffer from a high symptom burden due to their advanced disease. The severity of symptoms increases with depression and 4 or more points in the depression question of ESAS should lead to a closer diagnostic evaluation of depression. Symptom-centered palliative care including psychosocial aspects should be early integrated into the treatment of respiratory insufficiency.

Dyspnea on Exercise Is Associated with Overall Symptom Burden in Patients with Chronic Respiratory Insufficiency

Background: Patients with chronic respiratory insufficiency suffer from many symptoms together with dyspnea. Objective: We evaluated the association of dyspnea on exercise with other symptoms in patients with chronic respiratory insufficiency due to chronic obstructive pulmonary disease or interstitial lung disease. Design: This retrospective study included 101 patients in Tampere University Hospital, Finland. Dyspnea on exercise was assessed with modified Medical Research Council (mMRC) dyspnea questionnaire, and other symptoms were assessed with Edmonton Symptom Assessment System (ESAS) and Depression Scale (DEPS). The study was approved by Regional Ethics Committee of Tampere University Hospital, Finland (approval code R15180/December 1, 2015). Results: Patients with mMRC 4 (most severe dyspnea) compared with those with mMRC 0-3 reported higher symptom scores on ESAS in shortness of breath (median 8.0 [IQR 6.0-9.0] vs. 4.0 [2.0-6.0], p < 0.001), dry mouth (7.0 [4.0-8.0] vs. 3.0 [1.0-6.0], p < 0.001), tiredness (6.0 [3.0-7.0] vs. 3.0 [1.0-5.0], p < 0.001), loss of appetite (3.0 [0.0-6.0] vs. 1.0 [0.0-3.0], p = 0.001), insomnia (3.0 [1.0-7.0] vs. 2.0 [0.0-3.0], p = 0.027), anxiety (3.0 [0.0-5.5] vs. 1.0 [0.0-3.0], p = 0.007), and nausea (0.0 [0.0-2.0] vs. 0.0 [0.0-0.3], p = 0.027). Patients with mMRC 4 were more likely to reach the DEPS threshold for depression than those scoring mMRC 0-3 (42.1% vs. 20.8%, p = 0.028). Conclusions: Patients with chronic respiratory insufficiency need comprehensive symptom screening with relevant treatment, as they suffer from broad symptom burden worsening with increased dyspnea on exercise.

[Palliative Sedation at the End of Life: A Comparative Study of Chronic Obstructive Pulmonary Disease and Lung Cancer Patients]

BACKGROUND

Although patients with chronic obstructive pulmonary disease (COPD) receive poor-quality palliative care, information about the use of palliative sedation (PS) in the last days of life is very scarce.

OBJECTIVES

To compare the use of PS in hospitalized patients who died from COPD or lung cancer and identify factors correlating with PS application.

METHODS

In a retrospective observational cohort study, from 1,675 patients died at a teaching hospital between 2013 and 2015, 109 patients who died from COPD and 85 from lung cancer were compared. Sociodemographic data, clinical characteristics, health care resource utilization, application of PS and prescribed drugs were recorded.

RESULTS

In the last 6 months of life, patients who died from COPD had more hospital admissions due to respiratory causes and less frequent support by a palliative home care team (PHCT). Meanwhile, during their last hospitalization, patients who died from COPD had fewer do-not-resuscitate orders and were subjected to more intensive care unit admissions and cardiopulmonary resuscitation maneuvers. PS was applied less frequently in patients who died from COPD than in those who died from lung cancer (31 vs. 53%, p = 0.002). Overall, previous use of opioid drugs, support by a PHCT, and a diagnosis of COPD (adjusted odds ratio 0.48, 95% CI: 0.26-0.89, p = 0.020) were retained as factors independently related to PS. In COPD patients, only previous use of opioid drugs was identified as a PS-related factor.

CONCLUSION

During their last days of life, hospitalized COPD patients receive PS less frequently than patients with lung cancer.

Duration of palliative care before death in international routine practice: a systematic review and meta-analysis

BACKGROUND

Early provision of palliative care, at least 3-4 months before death, can improve patient quality of life and reduce burdensome treatments and financial costs. However, there is wide variation in the duration of palliative care received before death reported across the research literature. This study aims to determine the duration of time from initiation of palliative care to death for adults receiving palliative care across the international literature.

METHODS

We conducted a systematic review and meta-analysis that was registered with PROSPERO (CRD42018094718). Six databases were searched for articles published between Jan 1, 2013, and Dec 31, 2018: MEDLINE, Embase, CINAHL, Global Health, Web of Science and The Cochrane Library, as well undertaking citation list searches. Following PRISMA guidelines, articles were screened using inclusion (any study design reporting duration from initiation to death in adults palliative care services) and exclusion (paediatric/non-English language studies, trials influencing the timing of palliative care) criteria. Quality appraisal was completed using Hawker's criteria and the main outcome was the duration of palliative care (median/mean days from initiation to death).

RESULTS

One hundred sixty-nine studies from 23 countries were included, involving 11,996,479 patients. Prior to death, the median duration from initiation of palliative care to death was 18.9 days (IQR 0.1), weighted by the number of participants. Significant differences between duration were found by disease type (15 days for cancer vs 6 days for non-cancer conditions), service type (19 days for specialist palliative care unit, 20 days for community/home care, and 6 days for general hospital ward) and development index of countries (18.91 days for very high development vs 34 days for all other levels of development). Forty-three per cent of studies were rated as 'good' quality. Limitations include a preponderance of data from high-income countries, with unclear implications for low- and middle-income countries.

CONCLUSIONS

Duration of palliative care is much shorter than the 3-4 months of input by a multidisciplinary team necessary in order for the full benefits of palliative care to be realised. Furthermore, the findings highlight inequity in access across patient, service and country characteristics. We welcome more consistent terminology and methodology in the assessment of duration of palliative care from all countries, alongside increased reporting from less-developed settings, to inform benchmarking, service evaluation and quality improvement.

Survival and end-of-life aspects among subjects on long-term noninvasive ventilation

Background

The need for noninvasive ventilation (NIV) is commonly considered a predictor of poor survival, but life expectancy may vary depending on the underlying disease. We studied the factors associated with decreased survival and end-of-life characteristics in an unselected population of subjects starting NIV.

Methods

We conducted a retrospective study including 205 subjects initiating NIV from 1/1/2012-31/12/2015 who were followed up until 31/12/2017.

Results

The median survival time was shorter in subjects needing help with activities of daily living than in independent subjects (hazard ratio (HR) for death 1.7, 95% CI 1.2–2.6, P = 0.008) and was also shorter in subjects on long-term oxygen therapy (LTOT) than in those not on LTOT (HR for death 2.8, 95% CI 1.9–4.3, P < 0.001). There was marked difference in survival according to the disease necessitating NIV, and subjects with amyotrophic lateral sclerosis or interstitial lung disease seemed to have the shortest survival. The two most common diseases resulting in the need for NIV were chronic obstructive pulmonary disease (COPD) and obesity hypoventilation syndrome (OHS). The median survival time was 4.4 years in COPD subjects, but the median survival time was not reached in subjects with OHS (HR for death COPD vs. OHS: 3.2, 95% CI 1.9–5.5, P < 0.001). Most of the deceased subjects (55.6%) died in the hospital, while only 20.0% died at home. The last hospitalization admission leading to death occurred through the emergency room in 44.4% of the subjects.

Conclusions

Survival among subjects starting NIV in this real-life study varied greatly depending on the disease and degree of functional impairment. Subjects frequently died in the hospital after admission through the emergency department. A comprehensive treatment approach with timely advance care planning is therefore needed, especially for those needing help with activities of daily living and those with both NIV and LTOT.

Withdrawing noninvasive ventilation at end-of-life care: is there a right time?

PURPOSE OF REVIEW

The purpose of this review is the 'when' and 'how' of the matter of withdrawing noninvasive ventilation (NIV) at end-of-life (EoL) setting, having in mind the implications for patients, families and healthcare team.

RECENT FINDINGS

Several recent publications raised the place and potential applications of NIV at EoL setting. However, there are no clear guidelines about when and how to withdraw NIV in these patients. Continuing NIV in a failing clinical condition may unnecessarily prolong the dying process. This is particularly relevant as frequently, EoL discussions are started only when patients are in severe distress, and they have little time to discuss their preferences and decisions.

SUMMARY

Better advanced chronic disease and EoL condition definitions, as well as identification of possible scenarios, should help to decision-making and find the appropriate time to initiate, withhold and withdraw NIV. This review emphasized the relevance of an integrated approach across illness' trajectories and key transitions of patients who will need EoL care and such sustaining support measure.

Palliative care as an emerging role for respiratory health professionals: Findings from a cross-sectional, exploratory Canadian survey

Introduction

Respiratory Health Professionals (RHPs) with specialty training in the management of asthma and COPD, often care for patients with advanced respiratory disease, who have less access to palliative care than patients with similar disease burden. The aims of this study were to: (i) explore the current and desired roles of RHPs in terms of palliative care and (ii) examine barriers to discussions with patients about palliative care.

Methods

An online survey addressing the aims of this study was developed and pilot tested. The survey was distributed nationally using the database of the Lung Association's RESPTREC respiratory educator training program. Descriptive statistics were performed.

Results

A total of 123 completed surveys were returned, with respiratory therapists comprising the largest group of respondents. The majority indicated that end-of-life care was less than optimal for patients with advanced respiratory illnesses and agreed that palliative care should be a role of RHPs. Patient- and family-related barriers to having end-of-life discussions included: difficulty accepting prognosis, limitations and complications, and lack of capacity. For providers, the most important barriers were: lack of training, uncertainty about prognosis, and lack of time. The health care system barriers of concern were increasing demand for palliative care services and limited accessibility of palliative care for those with advanced respiratory diseases and difficulties in accurate prognostication for these conditions.

Discussion

Incorporating a more defined role in palliative care was generally seen as a desirable evolution of the RHP role. A number of strategies to mitigate identified barriers to discussions with the patient are described. Better alignment of the services required with the needs of patients with advanced respiratory disease can be addressed in a number of ways.

Conclusions

As RHP roles continue to evolve, consideration should be given to the ways in which RHPs can contribute to improving the quality of care for patients with advanced respiratory disease. Building collaborations with RHPs, palliative care, and other existing health programs can ensure high quality of care. Creating and taking advantage of learning opportunities to build skills and comfort in using a palliative approach will benefit respiratory patients.
