Advance Care Planning in Patients with Primary Malignant Brain Tumors: A Systematic Review

Assessing palliative care practices in intensive care units and interpreting them using the lens of appropriate care concepts. An umbrella review

PURPOSE

Intensive care units (ICUs) have significant palliative care needs but lack a reliable care framework. This umbrella review addresses them by synthesising palliative care practices provided at end-of-life to critically ill patients and their families before, during, and after ICU admission.

METHODS

Seven databases were systematically searched for systematic reviews, and the umbrella review was conducted according to the guidelines laid out by the Joanna Briggs Institute (JBI).

RESULTS

Out of 3122 initial records identified, 40 systematic reviews were included in the synthesis. Six key themes were generated that reflect the palliative and end-of-life care practices in the ICUs and their outcomes. Effective communication and accurate prognostications enabled families to make informed decisions, cope with uncertainty, ease distress, and shorten ICU stays. Inter-team discussions and agreement on a plan are essential before discussing care goals. Recording care preferences prevents unnecessary end-of-life treatments. Exceptional end-of-life care should include symptom management, family support, hydration and nutrition optimisation, avoidance of unhelpful treatments, and bereavement support. Evaluating end-of-life care quality is critical and can be accomplished by seeking family feedback or conducting a survey.

CONCLUSION

This umbrella review encapsulates current palliative care practices in ICUs, influencing patient and family outcomes and providing insights into developing an appropriate care framework for critically ill patients needing end-of-life care and their families.

Current status of advance care planning, palliative care consultation, and end-of-life care in patients with glioblastoma in South Korea

BACKGROUND

Given the typical trajectory of glioblastoma, many patients lose decision-making capacity over time, which can lead to inadequate advance care planning (ACP) and end-of-life (EOL) care. We aimed to evaluate patients' current ACP and EOL care status.

PATIENTS AND METHODS

We conducted a cohort study on 205 patients referred to oncologists at a Korean tertiary hospital between 2017 and 2022. We collected information on sociodemographic factors, cancer treatment, palliative care consultation, ACP, legal documents on life-sustaining treatment (LST) decisions, and aggressiveness of EOL care.

RESULTS

With a median follow-up time of 18.3 months: 159 patients died; median overall survival: 20.3 months. Of the 159 patients, 11 (6.9%) and 63 (39.6%) had advance directive (AD) and LST plans, respectively, whereas 85 (53.5%) had neither. Among the 63 with LST plans, 10 (15.9%) and 53 (84.1%) completed their forms through self-determination and family determination, respectively. Of the 159 patients who died, 102 (64.2%) received palliative care consultation (median time: 44 days from the first consultation to death) and 78 (49.1%) received aggressive EOL care. Those receiving palliative care consultations were less likely to receive aggressive EOL care (83.3% vs 32.4%, P < .001), and more likely to use more than 3 days of hospice care at EOL (19.6% vs 68.0%, P < .001).

CONCLUSIONS

The right to self-determination remains poorly protected among patients with glioblastoma, with nearly 90% not self-completing AD or LST plan. As palliative care consultation is associated with less aggressive EOL care and longer use of hospice care, physicians should promptly introduce patients to ACP conversations and palliative care consultations.

Benchmarking palliative care practices in neurooncology: a german perspective

PURPOSE

To benchmark palliative care practices in neurooncology centers across Germany, evaluating the variability in palliative care integration, timing, and involvement in tumor board discussions. This study aims to identify gaps in care and contribute to the discourse on optimal palliative care strategies.

METHODS

A survey targeting both German Cancer Society-certified and non-certified university neurooncology centers was conducted to explore palliative care frameworks and practices for neurooncological patients. The survey included questions on palliative care department availability, involvement in tumor boards, timing of palliative care integration, and use of standardized screening tools for assessing palliative burden and psycho-oncological distress.

RESULTS

Of 57 centers contacted, 46 responded (81% response rate). Results indicate a dedicated palliative care department in 76.1% of centers, with palliative specialists participating in tumor board discussions at 34.8% of centers. Variability was noted in the initiation of palliative care, with early integration at the diagnosis stage in only 30.4% of centers. The survey highlighted a significant lack of standardized spiritual care assessments and minimal use of advanced care planning. Discrepancies were observed in the documentation and treatment of palliative care symptoms and social complaints, underscoring the need for comprehensive care approaches.

CONCLUSION

The study highlights a diverse landscape of palliative care provision within German neurooncology centers, underscoring the need for more standardized practices and early integration of palliative care. It suggests the necessity for standardized protocols and guidelines to enhance palliative care's quality and uniformity, ultimately improving patient-centered care in neurooncology.

Summary of evidence to facilitate the implementation of advance care planning among advanced cancer patients

Advance care planning (ACP) is designed to ensure that patients lacking autonomous decision-making capacity receive medical services in accordance with their expectations and preferences. Individuals with advanced cancer are a crucial target for ACP implementation. However, the current practice of ACP in this group in China is suboptimal, demanding high-quality implementation evidence to strengthen ACP in the clinical practice of patients with advanced cancer. The existing literature can be summarized into 27 pieces of evidence across 7 dimensions, including initiation time, intervention content, intervention providers, intervention modalities, communication skills, outcome indicators, and environmental support. The aforementioned evidence could provide crucial support for improving ACP implementation for patients with advanced cancer. Subsequent research efforts should integrate patient preferences and explore the most suitable implementation strategies for ACP in the Chinese population with advanced cancer, considering diverse aspects such as traditional culture, ACP education and training, legislative support, and healthcare system refinement.

Communication in the context of glioblastoma treatment: A qualitative study of what matters most to patients, caregivers and health care professionals

BACKGROUND

Patients with glioblastoma have a poor prognosis and treatment is palliative in nature from diagnosis. It is therefore critical that the benefits and burdens of treatments are clearly discussed with patients and caregivers.

AIM

To explore experiences and preferences around glioblastoma treatment communication in patients, family caregivers and healthcare professionals.

DESIGN

Qualitative design. A thematic analysis of semi-structured interviews.

SETTING/PARTICIPANTS

A total of 15 adult patients with glioblastoma, 13 caregivers and 5 healthcare professionals were recruited from Leeds Teaching Hospitals NHS Trust.

RESULTS

Four themes were identified: (1) Communication practice and preferences. Risks and side-effects of anti-tumour treatments were explained clearly, with information layered and repeated. Treatment was often understood to be 'the only option'. Understanding the impact of side-effects could be enhanced, alongside information about support services. (2) What matters most. Patients/caregivers valued being well-supported by a trusted treatment team, feeling involved, having control and quality of life. Healthcare professionals similarly highlighted trust, maintaining independence and emotional support as key. (3) Decision-making. With limited treatment options, trust and control are crucial in decision-making. Patients ultimately prefer to follow healthcare professional advice but want to be involved, consider alternatives and voice what matters to them. (4) Impact of COVID-19. During the pandemic, greater efforts to maintain good communication were necessary. Negative impacts of COVID-19 were limited, caregivers appeared most disadvantaged by pandemic-related restrictions.

CONCLUSIONS

In glioblastoma treatment communication, where prognosis is poor and treatmentwill not result in cure, building trusting relationships, maintaining a sense of control and being well-informed are identified as critical.

Effect of palliative care decisions making on hospital service use at end-of-life in patients with malignant brain tumors: a retrospective study

BACKGROUND

Palliative care (PC) improves Quality of life and reduces the symptom burden. Aggressive treatments at end of life (EOL) postpone PC. The aim of this single-center retrospective study was to evaluate the timing of the PC decision i.e., termination of cancer-specific treatments and focusing on symptom-centered PC, and its impact on the use of tertiary hospital services at the EOL.

METHODS

A retrospective cohort study on brain tumor patients, who were treated at the Comprehensive Cancer Center of the Helsinki University Hospital from November 1993 to December 2014 and died between January 2013 and December 2014, were retrospectively reviewed. The analysis comprised 121 patients (76 glioblastoma multiforme, 74 males; mean age 62 years; range 26-89). The decision for PC, emergency department (ED) visits and hospitalizations were collected from hospital records.

RESULTS

The PC decision was made for 78% of the patients. The median survival after diagnosis was 16 months (13 months patients with glioblastoma), and after the PC decision, it was 44 days (range 1-293). 31% of the patients received anticancer treatments within 30 days and 17% within the last 14 day before death. 22% of the patients visited an ED, and 17% were hospitalized during the last 30 days of life. Of the patients who had a PC decision made more than 30 days prior to death, only 4% visited an ED or were hospitalized in a tertiary hospital in the last 30 days of life compared to patients with a late (< 30 days prior to death) or no PC decision (25 patients, 36%).

CONCLUSIONS

Every third patient with malignant brain tumors had anticancer treatments during the last month of life with a significant number of ED visits and hospitalizations. Postponing the PC decision to the last month of life increases the risk of tertiary hospital resource use at EOL.

Optimal care of people with brain cancer in the emergency department: A cross-sectional survey of outpatient perceptions

Objective

People diagnosed with brain cancer commonly present to the emergency department (ED). There is uncertainty about essential components and processes of optimal care from the perspective of consumers, and few guidelines exist to inform practice. This study examined the perceptions of outpatients and their support persons regarding what constitutes optimal care for people with brain cancer presenting to the ED.

Methods

A cross sectional descriptive survey study was undertaken. Participants included adults attending hospital outpatient clinics (n ​= ​181, 60% of eligible participants). Participants completed a survey assessing perceptions of optimal care for brain cancer patients presenting to emergency department and socio-demographic characteristics.

Results

The survey items endorsed as 'essential' by participants included that the emergency department team help patients: 'understand signs and symptoms to watch out for' (51%); 'understand the next steps in care and why' (48%); 'understand if their medical condition suggests it is likely they will die in hospital' (47%); 'ask patients if they have a substitute decision maker and want that person told they are in the emergency department' (44%); 'understand the purpose of tests and procedures' (41%).

Conclusions

Symptom management, effective communication and supported decision-making should be prioritised by ED teams. Further research to establish the views of those affected by brain cancer about essential care delivered in the ED setting, and to compare these views with the quality of care that is actually delivered, is warranted.

Why is advance care planning underused in oncology settings? A systematic overview of reviews to identify the benefits, barriers, enablers, and interventions to improve uptake

Background

Advance care planning (ACP) centres on supporting people to define and discuss their individual goals and preferences for future medical care, and to record and review these as appropriate. Despite recommendations from guidelines, rates of documentation for people with cancer are considerably low.

Aim

To systematically clarify and consolidate the evidence base of ACP in cancer care by exploring how it is defined; identifying benefits, and known barriers and enablers across patient, clinical and healthcare services levels; as well as interventions that improve advance care planning and are their effectiveness.

Methods

A systematic overview of reviews was conducted and was prospectively registered on PROSPERO. PubMed, Medline, PsycInfo, CINAHL, and EMBASE were searched for review related to ACP in cancer. Content analysis and narrative synthesis were used for data analysis. The Theoretical Domains Framework (TDF) was used to code barriers and enablers of ACP as well as the implied barriers targeted by each of the interventions.

Results

Eighteen reviews met the inclusion criteria. Definitions were inconsistent across reviews that defined ACP (n=16). Proposed benefits identified in 15/18 reviews were rarely empirically supported. Interventions reported in seven reviews tended to target the patient, even though more barriers were associated with healthcare providers (n=40 versus n=60, respectively).

Conclusion

To improve ACP uptake in oncology settings; the definition should include key categories that clarify the utility and benefits. Interventions need to target healthcare providers and empirically identified barriers to be most effective in improving uptake.

The Evolution of Palliative Medicine in Intensive Care

Supportive, or palliative, care has moved into medicine's mainstream with well-known and studied benefits but continues to be inadequately utilized in many health care environments particularly intensive care units (ICUs). With diverse patient populations in the various ICU settings, the supportive care team must adapt and mold their goals-of-care discussions and relationship building based on the ICU culture and individuals involved. Despite the differences in disease processes, early supportive care involvement in the ICU provides much needed emotional support and symptom management to patients and families in addition to identifying the patient's goals of care early in the hospital stay. The purpose of this article is to provide a general overview of the history of supportive care and clarify current misperceptions, particularly related to hospice, surrounding the specialty. The types of supportive care consults will be explained and their uses in the various ICU settings, and illustrate the advantage of early involvement to not only patients and families but the medical team as well.

Palliative care of older glioblastoma patients in neurosurgery

Purpose

The care of older neurosurgical patients at the end life is a particularly demanding challenge. Especially, the specific needs of very old patients with glioblastoma at the end of life are at risk of being deprived of adequate care.

Methods

Based on a narrative literature review, this article aims to explore key issues of the thematic intersection of geriatric glioblastoma patients, palliative care and neurosurgery.

Results and discussion

Four key issues were identified: patient-centeredness (need orientation and decision making), early palliative care, advance care planning, and multi-professionalism. Possible benefits and barriers are highlighted with regard to integrating these concepts into neurosurgery.

Conclusions

Palliative care complements neurosurgical care of geriatric glioblastoma multiforme patients to optimise care for this highly vulnerable category of patients.

Adolescent and young adult brain tumors: current topics and review

The management of brain tumors developed in adolescents and young adults (AYAs) is challenging because of their histological heterogeneity and low incidence. The brain tumor and its treatment interventions can negatively affect neurological, neurocognitive, and endocrinological function, and dramatically affect the circumstances of AYA patients progressing to further education, employment, and marriage. Specific support is thus necessary to maintain the quality of life (QOL) of AYA brain tumor patients. AYA patients and survivors require active intervention and support for returning to school or work, progressing to further education, finding employment, and preserving fertility. Recent cancer genome profiling revealed that AYA gliomas include pediatric- and adult-type genetic alteration. Insights into the biology underlying the distribution of tumors in AYAs may influence the development of prospective trials. A more individualized view of brain tumors may influence stratification of patients' in future clinical studies as well as selection for molecular targeted therapy. Here I review strategies for achieving a better outcome to decrease late effects and improve QOL.

Advance Care Planning in Neurodegenerative Disorders: A Scoping Review

Advance care planning (ACP) is increasingly acknowledged as a key step to enable patients to define their goals/preferences for future medical care, together with their carers and health professionals. We aimed to map the evidence on ACP in neurodegenerative disorders. We conducted a scoping review by searching PubMed (inception-December 28, 2020) in addition to trial, review, and dissertation registers. From 9367 records, we included 53 studies, mostly conducted in Europe (45%) and US-Canada (41%), within the last five years. Twenty-six percent of studies were qualitative, followed by observational (21%), reviews (19%), randomized controlled trials (RCTs, 19%), quasi-experimental (11%), and mixed-methods (4%). Two-thirds of studies addressed dementia, followed by amyotrophic lateral sclerosis (13%), and brain tumors (9%). The RCT interventions (all in dementia) consisted of educational programs, facilitated discussions, or videos for patients and/or carers. In conclusion, more research is needed to investigate barriers and facilitators of ACP uptake, as well as to develop/test interventions in almost all the neurodegenerative disorders. A common set of outcome measures targeting each discrete ACP behavior, and validated across the different diseases and cultures is also needed.

Reforming support systems of newly diagnosed brain cancer patients: a systematic review

PURPOSE

Despite the increasing incidence of currently incurable brain cancer, limited resources are placed in patients' support systems, with reactive utilisation late in the disease course, when physical and psychological symptoms have peaked. Based on patient-derived data and emphasis on service improvement, this review investigated the structure and efficacy of the support methods of newly diagnosed brain cancer patients in healthcare systems.

METHODS

This systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. Articles from PubMed, Embase, and CENTRAL databases were screened with six pre-established eligibility criteria, including assessment within 6 months from diagnosis of a primary malignant brain tumour. Risk of bias was evaluated using the Newcastle-Ottawa Scale and Critical Appraisal Skills Program (CASP) Qualitative Studies Checklist.

RESULTS

Of 5057 original articles, 14 were eligible for qualitative synthesis. Four studies were cross-sectional and ten were descriptive. Information given to patients was evaluated in seven studies, communication with patients in nine, and patient participation in treatment decisions in eight. Risk of bias was low in ten studies, moderate in two, and high in two.

CONCLUSIONS

Techniques promoting individualised care increased perceived support, despite poor patient-physician communication and complexity of the healthcare system. Extracted data across 14 included studies informed a set of guidelines and a four-step framework. These can help evaluate and reform healthcare services to better accommodate the supportive needs of this patient group.

Prognostication in brain tumors

Despite the use of aggressive multimodality therapies, the prognosis of brain tumor patients remains poor. Tumors of glial origin typically have the worst prognosis, with a predicted median survival of 12-15months for glioblastoma multiforme (WHO grade IV) and 2-5years for anaplastic glioma (WHO grade III). Palliative care problems and needs in patients with primary and secondary brain tumors are significantly different, both due to different trajectory of disease and to variable prognosis which in metastatic brain tumors is related to the natural history of primary tumors. This chapter describes the complex interactions influencing communication and the treatment decision process in primary brain tumor patients. The whole trajectory of disease and particularly the end-of-life (EOL) phase of brain tumor (BT) patients are quite different in respect to the expected trajectory observed in the general cancer population. The need to improve the communication of prognosis in BT patients has been clearly reported in neuro-oncological literature, but several issues may hinder a good communication in these patients. Adequate prognostic awareness (PA) is important for several reasons: to respect patient autonomy, to obtain her/his preferences about treatments and goal of care, and to share EOL treatment decisions. The high incidence of cognitive deficits in BT patients is one of the most challenging issues influencing the quality of communication and the participation of patients in the process of treatment decisions. Impaired neurocognitive functions may impact capacities of understanding, appreciation, reasoning, and expression of choice, reducing Medical Decisions Capacity (MDC). The lack of capacity to express preferences about EOL treatment decisions represents an important ethical issue, with a great impact on both the patient's family and healthcare professionals involved in the decision processes. Also, patients' coping styles may have an important influence in critical aspects of care such as communication of diagnosis and prognosis, discussion with patients and their caregivers about goal of treatments, early introduction of PC, and advanced planning of patients' preferences concerning EOL treatment and issues. Several barriers hinder good communication in BT patients. This chapter analyzes emerging literature data and possible strategies to improve communication about prognosis and goals of care and to promote patients' involvement in the treatment decision process particularly in the palliative care setting.

Aggressiveness of care at end of life in patients with high-grade glioma

Background

Patients with high‐grade glioma (HGG) face unique challenges toward the end of life (EoL), given their aggressive trajectory and neurologic deterioration. Aggressiveness of medical care at EoL has been identified as an important quality metric for oncology patients. At this time, limited data exist around the nature of EoL care of patients with HGG.

Methods

Patients with HGG and palliative care (PC) referral seen between 2010 and 2015 were identified (N = 80). Of these, N = 52 met inclusion criteria. Random selections of patients with (1) HGG not referred to PC (n = 80), and (2) non‐CNS cancers with PC referral (n = 80) were identified for comparison. A composite score of aggressiveness of medical care at EoL was calculated for each patient from predetermined variables. A time of eligibility for PC was defined for each patient when predetermined criteria based on symptom burden, functional status, and prognosis were met.

Results

Among the patients analyzed with HGG referred to PC, 59.6% (N = 31) were referred as inpatients, and 53.8% (N = 28) were referred within the last 12 weeks of life. Patients with HGG had similar aggressiveness of care at EoL regardless of PC referral, and HGG patients had less aggressive care at EoL than patients with non‐CNS cancers (p = 0.007). Care was more aggressive at EoL in HGG patients who received late versus early PC referrals (p = 0.012). Motor weakness at time of eligibility (OR = 2.55, p = 0.002) and more disease progressions (OR = 1.25, p = 0.043) were associated with less aggressive care at EoL.

Conclusions

Early clinical‐ and disease‐related features predict the aggressiveness of medical care at EoL in patients with HGG. Formal PC consultation is used infrequently and suboptimally in patients with HGG. Our data suggest that the role of PC in improving EoL outcomes in HGG warrants further evaluation.

Influence of individual, illness and environmental factors on place of death among people with neurodegenerative diseases: a retrospective, observational, comparative cohort study

BACKGROUND

In long-term neurological conditions, location of death is poorly understood but is seen as a marker of quality of dying.

OBJECTIVE

To examine individual, illness and environmental factors on place of death among people with multiple sclerosis (MS) and Parkinson's disease (PD) in isolation or in combination and compare them with people without either condition.

METHODS

Retrospective, observational, comparative cohort study of 582 people with MS, 579 people with PD and 95 controls from UK Multiple Sclerosis and Parkinson's Disease Tissue Bank. A subset of people with MS and PD were selected for analysis of individual clinical encounters 2 years before death and further subset of all groups for analysis of impact of advance care planning (ACP) and recognition of dying.

RESULTS

People with MS died more often (50.8%) in hospital than those with PD (35.3%). Examining individual clinical encounters over 2 years (4931 encounters) identified increased contact with services 12 months before death (F(1, 58)=69.71, p<0.0001) but was not associated with non-hospital deaths (F(1, 58)=1.001, p=0.321). The presence of ACPs and recognition of dying were high among people with MS and PD and both associated with a non-hospital death. ACPs were more likely to prevent hospital deaths when initiated by general practitioners (GPs) compared with other professional groups (χ2=68.77, p=0.0007).

CONCLUSIONS

For people with MS and PD, ACPs contribute to reducing dying in hospital. ACPs appear to be most effective when facilitated by GPs underlining the importance of primary care involvement in delivering holistic care at the end of life.

Brain cancer patient and support persons' experiences of psychosocial care: a mapping of research outputs

BACKGROUND

People with brain cancer and their support persons (SPs) are critical sources of information on the components of care that contribute to psychosocial outcomes.

AIMS

To determine the proportion of studies that examined (1) at least one of 14 nominated components of psychosocial cancer care and (2) more than one component of care.

METHODS

Medline, The Cochrane Library, PsycINFO and Embase were electronically searched for publications from January 1999 to December 2019. Publications that met the inclusion criteria were coded according to the number and type of psychosocial care components assessed from 14 listed components, and whether patient and/or SPs' views about care were elicited.

RESULTS

Of the 113 included publications, 61 publications included patient-reported data only (54%), 27 included both patient and SP-reported data (24%) and 25 included SP-reported data only (22%). Most assessed a single component of care (77% of patient-reported and 71% of SP-reported). No publications assessed all 14 components. The "Psychosocial" component was the most frequently assessed component of care for patient-reported (n = 80/88, 91%) and SP-reported publications (n = 46/52, 88%).

CONCLUSIONS

Publications reporting on psychosocial care in brain cancer present a relatively narrow view of patient and support person experiences. The inclusion of both patient and support person perspectives and the assessment of multiple components of care are required in future research to optimize psychosocial outcomes in brain cancer.

A descriptive analysis of end-of-life discussions for high-grade glioma patients

Background

End-of-life discussions (EOLDs) in patients with high-grade glioma (HGG) have not been well described. Therefore, this study examined the appropriateness of timing and the extent of patient involvement in EOLDs and their impact on HGG patients.

Methods

A cross-sectional survey was conducted among 105 bereaved families of HGG patients at a university hospital in Japan between July and August 2019. Fisher's exact test and the Wilcoxon rank-sum test were used to assess the association between patient participation in EOLDs and their outcomes.

Results

In total, 77 questionnaires were returned (response rate 73%), of which 20 respondents replied with refusal documents. Overall, 31/57 (54%) participated in EOLDs at least once in acute hospital settings, and a significant difference was observed between participating and nonparticipating groups in communicating the patient's wishes for EOL care to the family (48% vs 8%, P = .001). Moreover, >80% of respondents indicated that the initiation of EOLDs during the early diagnosis period with patients and families was appropriate. Most EOLDs were provided by neurosurgeons (96%), and other health care providers rarely participated. Additionally, patient goals and priorities were discussed in only 28% of the EOLDs. Patient participation in EOLDs was not associated with the quality of EOL care and a good death.

Conclusions

Although participation in EOLDs is relatively challenging for HGG patients, this study showed that participation in EOLDs may enable patients to express their wishes regarding EOL care. It is important to initiate EOLDs early on through an interdisciplinary team approach while respecting patient goals and priorities.

Quality of online self-management resources for adults living with primary brain cancer, and their carers: a systematic environmental scan

Background

A primary brain cancer diagnosis is a distressing, life changing event. It adversely affects the quality of life for the person living with brain cancer and their families (‘carers’). Timely access to evidence-based information is critical to enabling people living with brain cancer, and their carers, to self-manage the devastating impacts of this disease.

Method

A systematic environmental scan of web-based resources. A depersonalised search for online English-language resources published from 2009 to December 2019 and designed for adults (> 25 years of age), living with primary brain cancer, was undertaken using the Google search engine. The online information was classified according to: 1) the step on the cancer care continuum; 2) self-management domains (PRISMS taxonomy); 3) basic information disclosure (Silberg criteria); 4) independent quality verification (HonCode); 5) reliability of disease and treatment information (DISCERN Sections 1 and 2); and readability (Flesch-Kincaid reading grade).

Results

A total of 119 online resources were identified, most originating in England (n = 49); Australia (n = 27); or the USA (n = 27). The majority of resources related to active treatment (n = 76), without addressing recurrence (n = 3), survivorship (n = 1) or palliative care needs (n = 13). Few online resources directly provided self-management advice for adults living with brain cancer or their carers. Just over a fifth (n = 26, 22%) were underpinned by verifiable evidence. Only one quarter of organisations producing resources were HonCode certified (n = 9, 24%). The median resource reliability as measured by Section 1, DISCERN tool, was 56%. A median of 8.8 years of education was required to understand these online resources.

Conclusions

More targeted online information is needed to provide people affected by brain cancer with practical self-management advice. Resources need to better address patient and carer needs related to: rehabilitation, managing behavioural changes, survivorship and living with uncertainty; recurrence; and transition to palliative care. Developing online resources that don’t require a high level of literacy and/or cognition are also required.

Increased complication and mortality among non-index hospital readmissions after brain tumor resection is associated with low-volume readmitting hospitals

OBJECTIVE

Fragmentation of care following craniotomy for tumor resection is increasingly common with the regionalization of neurosurgery. Hospital readmission to a hospital (non-index) other than the one from which patients received their original care (index) has been associated with increases in both morbidity and mortality for cancer patients. The impact of non-index readmission after surgical management of brain tumors has not previously been evaluated. The authors set out to determine rates of non-index readmission following craniotomy for tumor resection and evaluated outcomes following index and non-index readmissions.

METHODS

Retrospective analyses of data from cases involving resection of a primary brain tumor were conducted using data from the Nationwide Readmissions Database (NRD) for 2010-2014. Multivariate logistic regression was used to evaluate the independent association of patient and hospital factors with readmission to an index versus non-index hospital. Further analysis evaluated association of non-index versus index hospital readmission with mortality and major complications during readmission. Effects of readmission hospital procedure volume on mortality and morbidity were evaluated in post hoc analysis.

RESULTS

In a total of 17,459 unplanned readmissions, 84.4% patients were readmitted to index hospitals and 15.6% to non-index hospitals. Patient factors associated with increased likelihood of non-index readmission included older age (75+: OR 1.44, 95% CI 1.19-1.75), elective index admission (OR 1.19, 95% CI 1.08-1.30), increased Elixhauser comorbidity score ≥2 (OR 1.18, 95% CI 1.01-1.37), and malignant tumor diagnosis (OR 1.32, 95% CI 1.19-1.45) (all p < 0.04). Readmission to a non-index facility was associated with a 28% increase in major complications (OR 1.28, 95% CI 1.14-1.43, p < 0.001) and 21% increase in mortality (OR 1.21, 95% CI 1.02-1.44, p = 0.032) in initial analysis. Following a second multivariable logistic regression analysis including the readmitting hospital characteristics, low procedure volume of a readmitting facility was significantly associated with non-index readmission (p < 0.001). Readmission to a lower-procedure-volume facility was associated with a 46%-75% increase in mortality (OR 1.46-1.75, p < 0.005) and a 21%-35% increase in major complications (OR 1.21-1.34, p < 0.005). Following adjustment for volume at a readmitting facility, admission to a non-index facility was no longer associated with mortality (OR 0.90, 95% CI 0.71-1.14, p = 0.378) or major complications (OR 1.09, CI 0.94-1.26, p = 0.248).

CONCLUSIONS

Of patient readmissions following brain tumor resection, 15.6% occur at a non-index facility. Low procedure volume is a confounder for non-index analysis and is associated with an increased likelihood of major complications and mortality, as compared to readmission to high-procedure-volume hospitals. Further studies should evaluate interventions targeting factors associated with unplanned readmission.

Palliative Care in High-Grade Glioma: A Review

High-grade glioma (HGG) is characterized by debilitating neurologic symptoms and poor prognosis. Some of the suffering this disease engenders may be ameliorated through palliative care, which improves quality of life for seriously ill patients by optimizing symptom management and psychosocial support, which can be delivered concurrently with cancer-directed treatments. In this article, we review palliative care needs associated with HGG and identify opportunities for primary and specialty palliative care interventions. Patients with HGG and their caregivers experience high levels of distress due to physical, emotional, and cognitive symptoms that negatively impact quality of life and functional independence, all in the context of limited life expectancy. However, patients typically have limited contact with specialty palliative care until the end of life, and there is no established model for ensuring their palliative care needs are met throughout the disease course. We identify low rates of advance care planning, misconceptions about palliative care being synonymous with end-of-life care, and the unique neurologic needs of this patient population as some of the potential barriers to increased palliative interventions. Further research is needed to define the optimal roles of neuro-oncologists and palliative care specialists in the management of this illness and to establish appropriate timing and models for palliative care delivery.

Deconstructing the Complexities of Advance Care Planning Outcomes: What Do We Know and Where Do We Go? A Scoping Review

BACKGROUND/OBJECTIVES

Advance care planning (ACP) has shown benefit in some, but not all, studies. It is important to understand the utility of ACP. We conducted a scoping review to identify promising interventions and outcomes.

DESIGN

Scoping review.

MEASUREMENTS

We searched MEDLINE/PubMed, EMBASE, CINAHL, PsycINFO, and Web of Science for ACP randomized controlled trials from January 1, 2010, to March 3, 2020. We used standardized Preferred Reporting Items for Systematic Review and Meta-Analyses methods to chart study characteristics, including a standardized ACP Outcome Framework: Process (e.g., readiness), Action (e.g., communication), Quality of Care (e.g., satisfaction), Health Status (e.g., anxiety), and Healthcare Utilization. Differences between arms of P < .05 were deemed positive.

RESULTS

Of 1,464 articles, 69 met eligibility; 94% were rated high quality. There were variable definitions, age criteria (≥18 to ≥80 years), diseases (e.g., dementia and cancer), and settings (e.g., outpatient and inpatient). Interventions included facilitated discussions (42%), video only (20%), interactive, multimedia (17%), written only (12%), and clinician training (9%). For written only, 75% of primary outcomes were positive, as were 69% for multimedia programs; 67% for facilitated discussions, 59% for video only, and 57% for clinician training. Overall, 72% of Process and 86% of Action outcomes were positive. For Quality of Care, 88% of outcomes were positive for patient-surrogate/clinician congruence, 100% for patients/surrogate/clinician satisfaction with communication, and 75% for surrogate satisfaction with patients' care, but not for goal concordance. For Health Status outcomes, 100% were positive for reducing surrogate/clinician distress, but not for patient quality of life. Healthcare Utilization data were mixed.

CONCLUSION

ACP is complex, and trial characteristics were heterogeneous. Outcomes for all ACP interventions were predominantly positive, as were Process and Action outcomes. Although some Quality of Care and Health Status outcomes were mixed, increased patient/surrogate satisfaction with communication and care and decreased surrogate/clinician distress were positive. Further research is needed to appropriately tailor interventions and outcomes for local contexts, set appropriate expectations of ACP outcomes, and standardize across studies.

"It Makes People Uneasy, but It's Necessary. #BTSM": Using Twitter to Explore Advance Care Planning among Brain Tumor Stakeholders

Background: Advance care planning (ACP) often occurs too late in the disease course of those who are affected by brain tumors. Furthermore, the perspectives of brain tumor stakeholders on ACP are not well described. We reviewed a social media tweet chat to understand barriers to ACP experienced by brain tumor stakeholders. Methods: We used qualitative methods to analyze a tweet chat (real-time virtual discussion) of brain tumor stakeholders. The one-hour tweet chat was hosted by Brain Tumor Social Media chat (@BTSMchat), a patient-run Twitter community, in January 2018. Participants reflected on four questions about ACP by including the hashtag "#BTSM" in tweets. Unique tweets and stakeholder type (i.e., patient, caregiver, advocate or organization member, clinician or researcher, or @BTSMchat leader) were coded. The tweet chat was qualitatively analyzed to identify key themes. Results: A total of 52 participants from four countries contributed 336 tweets. Most participants were patients (people with brain tumors), followed by clinicians or researchers, and advocates or organizations. Three key themes emerged regarding brain tumor stakeholder perspectives about ACP: (1) attitudinal barriers prevent discussions of death; (2) need to ensure one's voice is heard; and (3) Goldilock's approach to timing-fearing ACP is too early or too late. Conclusions: Various stakeholders, including people with brain tumors, shared perspectives on ACP through a tweet chat and highlighted important challenges and opportunities. Twitter is a new avenue for patients, clinicians, and advocates to engage with each other to better understand each other's perspectives related to ACP.

Top Ten Tips Palliative Care Clinicians Should Know When Caring for Patients with Brain Cancer

The diagnosis of an aggressive, primary brain tumor is life altering for those affected and too often portends a poor prognosis. Despite decades of research, neither a cure nor even a therapy that reliably and dramatically prolongs survival has been found. Fortunately, there are a number of treatments that may prolong the life of select brain tumor patients although the symptom burden can sometimes be high. This article brings together neuro-oncologists, neurologists, and palliative care (PC) physicians to help shine a light on these diseases, their genetics, treatment options, and the symptoms likely to be encountered both from the underlying illness and its treatment. We hope to increase the understanding that PC teams have around these illnesses to improve care for patients and families.

Advance care planning in glioblastoma patients: development of a disease-specific ACP program

BACKGROUND

It is unknown if the implementation of an advance care planning (ACP) program is feasible in daily clinical practice for glioblastoma patients. We aimed to develop an ACP program and assess the preferred content, the best time to introduce such a program in the disease trajectory, and possible barriers and facilitators for participation and implementation.

METHODS

A focus group with health care professionals (HCPs) and individual semi-structured interviews with patients and proxies (of both living and deceased patients) were conducted.

RESULTS

All predefined topics were considered relevant by participants, including the current situation, worries/fears, (supportive) treatment options, and preferred place of care/death. Although HCPs and proxies of deceased patients indicated that the program should be implemented relatively early in the disease trajectory, patient-proxy dyads were more ambiguous. Several patient-proxy dyads indicated that the program should be initiated later in the disease trajectory. If introduced early, topics about the end of life should be postponed. A frequently mentioned barrier for participation was that the program would be too confronting, while a facilitator was adequate access to information.

CONCLUSION

This study resulted in an ACP program specifically for glioblastoma patients. Although participants agreed on the program content, the optimal timing of introducing such a program was a matter of debate. Our solution is to offer the program shortly after diagnosis but let patients and proxies decide which topics they want to discuss and when. The impact of the program on several patient- and care-related outcomes will be evaluated in the next step.

Hypofractionated radiation therapy versus chemotherapy with temozolomide in patients affected by RPA class V and VI glioblastoma: a randomized phase II trial

INTRODUCTION

In RPA V-VI glioblastoma patients both hypofractionated radiotherapy and exclusive temozolomide can be used; the purpose of this trial is to compare these treatment regimens in terms of survival and quality of life.

METHODS

Patients with histologic diagnosis of glioblastoma were randomized to hypofractionated radiotherapy (RT-30 Gy in 6 fractions) and exclusive chemotherapy (CHT-emozolomide 200 mg/m²/day 5 days every 28 days). Overall (OS) and progression free survival (PFS) were evaluated with Kaplan Maier curves and correlated with prognostic factors. Quality- adjusted survival (QaS) was evaluated according to the Murray model (Neurological Sign and Symptoms-NSS) RESULTS: From 2010 to 2015, 31 pts were enrolled (CHT: 17 pts; RT: 14pts). Four pts were excluded from the analysis. RPA VI (p = 0.048) and absence of MGMT methylation (p = 0.001) worsened OS significantly. Biopsy (p = 0.048), RPA class VI (p = 0.04) and chemotherapy (p = 0.007) worsened PFS. In the two arms the initial NSS scores were overlapping (CHT: 12.23 and RT: 12.30) and progressively decreased in both group and became significantly worse after 5 months in CHT arm (p = 0.05). Median QaS was 104 days and was significantly better in RT arm (p = 0.01).

CONCLUSIONS

The data obtained are limited by the poor accrual. Both treatments were well tolerated. Patients in RT arm have a better PFS and QaS, without significant differences in OS. The deterioration of the NSS score would seem an important parameter and coincide with disease progression rather than with the toxicity of the treatment.

The Role of Palliative Care in Chronic Progressive Neurological Diseases-A Survey Amongst Neurologists in the Netherlands

Background: Chronic progressive neurological diseases like high grade glioma (HGG), Parkinson's disease (PD), and multiple sclerosis (MS) are incurable, and associated with increasing disability including cognitive impairment, and reduced life expectancy. Patients with these diseases have complex care needs. Therefore, timely advance care planning (ACP) is required. Our aim was to investigate timing and content of discussions on treatment restrictions, i.e., to initiate, withhold, or withdraw treatment in patients with HGG, PD, and MS, from the neurologists' perspective. Methods: We performed a national online survey amongst consultants in neurology and residents in The Netherlands. The questionnaire focused on their daily practice concerning timing and content of discussions on treatment restrictions with patients suffering from HGG, PD or MS. We also inquired about education and training in discussing these issues. Results: A total of 125 respondents [89 neurologists (71%), 62% male, with a median age of 44 years, and 36 residents (29%), 31% male with a median age of 29 years] responded. Initial discussions on treatment restrictions were said to take place during the first year after diagnosis in 28% of patients with HGG, and commonly no earlier than in the terminal phase in patients with PD and MS. In all conditions, significant cognitive decline was the most important trigger to advance discussions, followed by physical decline, and initiation of the terminal phase. Most discussed issues included ventilation, resuscitation, and admission to the intensive care unit. More than half of the consultants in neurology and residents felt that they needed (more) education and training in having discussions on treatment restrictions. Conclusion: In patients with HGG discussions on treatment restrictions are initiated earlier than in patients with PD or MS. However, in all three diseases these discussions usually take place when significant physical and cognitive decline has become apparent and commonly mark the initiation of end-of-life care. More than half of the responding consultants in neurology and residents feel the need for improvement of their skills in performing these discussions.

A Systematic Review in Support of the National Consensus Project Clinical Practice Guidelines for Quality Palliative Care, Fourth Edition

CONTEXT

Palliative care continues to be a rapidly growing field aimed at improving quality of life for patients and their caregivers.

OBJECTIVES

The purpose of this review was to provide a synthesis of the evidence in palliative care to inform the fourth edition of the National Consensus Project Clinical Practice Guidelines for Quality Palliative Care.

METHODS

Ten key review questions addressing eight content domains guided a systematic review focused on palliative care interventions. We searched eight databases in February 2018 for systematic reviews published in English from 2013, after the last edition of National Consensus Project guidelines was published, to present. Experienced literature reviewers screened, abstracted, and appraised data per a detailed protocol registered in PROSPERO. The quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluations criteria. The review was supported by a technical expert panel.

RESULTS

We identified 139 systematic reviews meeting inclusion criteria. Reviews addressed the structure and process of care (interdisciplinary team care, 13 reviews; care coordination, 18 reviews); physical aspects (48 reviews); psychological aspects (26 reviews); social aspects (two reviews); spiritual, religious, and existential aspects (11 reviews); cultural aspects (three reviews); care of the patient nearing the end of life (grief/bereavement programs, six reviews; final days of life, two reviews); ethical and legal aspects (36 reviews).

CONCLUSION

A substantial body of evidence exists to support clinical practice guidelines for quality palliative care, but the quality of evidence is limited.

Overview of Systematic Reviews of Advance Care Planning: Summary of Evidence and Global Lessons

BACKGROUND

Advance care planning (ACP) involves important decision making about future medical needs. The high-volume and disparate nature of ACP research makes it difficult to grasp the evidence and derive clear policy lessons for policymakers and clinicians.

AIM

The aim of this study was to synthesize ACP research evidence and identify relevant contextual elements, program features, implementation principles, and impacted outcomes to inform policy and practice.

DESIGN

An overview of systematic reviews using the Cochrane Handbook of Systematic Reviews of Interventions was performed. Study quality was assessed using a modified version of the AMSTAR (A MeaSurement Tool to Assess Reviews) tool.

DATA SOURCES

MEDLINE, EBM Reviews, Cochrane Reviews, CINAHL, Global Health, PsycINFO, and EMBASE were searched for ACP-related research from inception of each database to April 2017. Searches were supplemented with gray literature and manual searches. Eighty systematic reviews, covering over 1660 original articles, were included in the analysis.

RESULTS

Legislations, institutional policies, and cultural factors influence ACP development. Positive perceptions toward ACP do not necessarily translate into more end-of-life conversations. Many factors related to patients' and providers' attitudes, and perceptions toward life and mortality influence ACP implementation, decision making, and completion. Limited, low-quality evidence points to several ACP benefits, such as improved end-of-life communication, documentation of care preferences, dying in preferred place, and health care savings. Recurring features that make ACP programs effective include repeated and interactive discussion sessions, decision aids, and interventions targeting multiple stakeholders.

CONCLUSIONS

Preliminary evidence highlights several elements that influence the ACP process and provides a variety of features that could support successful, effective, and sustainable ACP implementation. However, this evidence is compartmentalized and limited. Further studies evaluating ACP as a unified program and assessing the impact of ACP for different populations, settings, and contexts are needed to develop programs that are able to unleash ACP's full potential.

Palliative Care, End-of-Life Care, and Advance Care Planning in Neuro-oncology

PURPOSE OF REVIEW

Despite new therapeutic approaches, most patients with high-grade glioma face limited overall survival and have a high symptom burden throughout their disease trajectory, especially in the end-of-life phase. This article provides an overview of the role of palliative care in neuro-oncology. Management recommendations are made for neurologic symptoms in patients with advanced brain tumors, including headaches, nausea, and fatigue. Special attention is given to how and when to involve subspecialty palliative care and hospice services to improve symptom management during active tumor treatment and in the end-of-life phase of patients with brain tumors. Advance care planning and end-of-life goals should be addressed early in the disease trajectory; this article provides a road map for these discussions.

RECENT FINDINGS

The high symptom burden of patients with brain tumors affects their quality of life as well as their ability to make treatment decisions. It is therefore warranted to involve patients with high-grade glioma in treatment decision making early in the disease course, with a focus on end-of-life care and advance care planning. Research in other World Health Organization grade IV cancers has shown that the early involvement of specialty palliative care improves quality of life and caregiver satisfaction. Patients with brain tumors should be actively screened for fatigue, and underlying factors such as hormone deficiencies, low blood counts, and sleep issues should be addressed before focusing interventions for tumor- and treatment-related fatigue.

SUMMARY

Palliative care can address typical symptoms, such as fatigue, nausea, and headaches that have the potential to severely disable patients with brain tumors. Advance care planning should be introduced proactively and early in the disease trajectory to ensure a dignified death and improved caregiver bereavement.

State of advance care planning research: A descriptive overview of systematic reviews

OBJECTIVE

To provide an overview of the current state of research of advance care planning (ACP), highlighting most studied topics, publication time, quality of studies and reported outcomes, and to identify gaps to improve ACP receptivity, utilization, implementation, and outcomes.

METHOD

Cochrane methodology for conducting overviews of systematic reviews. Study quality was assessed using a modified version of the Assessing the Methodological Quality of Systematic Reviews tool. The following databases were searched from inception to April 2017: MEDLINE, EBM Reviews, Cochrane Reviews, CINAHL, Global Health, PsycINFO, and EMBASE. Searches were supplemented with gray literature and manual searches.

RESULT

Eighty systematic reviews, covering 1,662 single articles, show that ACP-related research focuses on nine main topics: (1) ACP as part of end-of-life or palliative care interventions, (2) care decision-making; (3) communication strategies; (4) factors influencing ACP implementation; (5) ACP for specific patient groups, (6) ACP effectiveness; (7) ACP experiences; (8) ACP cost; and (9) ACP outcome measures. The majority of this research was published since 2014, its quality ranges from moderate to low, and reports on documentation, concordance, preferences, and resource utilization outcomes.

SIGNIFICANCE OF RESULTS

Despite the surge of ACP research, there are major knowledge gaps about ACP initiation, timeliness, optimal content, and impact because of the low quality and fragmentation of the available evidence. Research has mostly focused on discrete aspects within ACP instead of using a holistic evaluative approach that takes into account its intricate working mechanisms, the effects of systems and contexts, and the impacts on multilevel stakeholders. Higher quality studies and innovative interventions are needed to develop effective ACP programs and address research gaps.

End-of-Life Care in High-Grade Glioma Patients. The Palliative and Supportive Perspective

High-grade gliomas (HGGs) are the most frequently diagnosed primary brain tumors. Even though it has been demonstrated that combined surgical therapy, chemotherapy, and radiotherapy improve survival, HGGs still harbor a very poor prognosis and limited overall survival. Differently from other types of primary neoplasm, HGG manifests also as a neurological disease. According to this, palliative care of HGG patients represents a peculiar challenge for healthcare providers and caregivers since it has to be directed to both general and neurological cancer symptoms. In this way, the end-of-life (EOL) phase of HGG patients appears to be like a journey through medical issues, progressive neurological deterioration, and psychological, social, and affective concerns. EOL is intended as the time prior to death when symptoms increase and antitumoral therapy is no longer effective. In this phase, palliative care is intended as an integrated support aimed to reduce the symptoms burden and improve the Quality Of Life (QOL). Palliative care is represented by medical, physical, psychological, spiritual, and social interventions which are primarily aimed to sustain patients&rsquo; functions during the disease time, while maintaining an acceptable quality of life and ensuring a dignified death. Since HGGs represent also a family concern, due to the profound emotional and relational issues that the progression of the disease poses, palliative care may also relieve the distress of the caregivers and increase the satisfaction of patients&rsquo; relatives. We present the results of a literature review addressed to enlighten and classify the best medical, psychological, rehabilitative, and social interventions that are addressed both to patients and to their caregivers, which are currently adopted as palliative care during the EOL phase of HGG patients in order to orientate the best medical practice in HGG management.

Impact of advance care planning on end-of-life management

PURPOSE OF REVIEW

The aim of this review is to critically appraise the recent evidence on different aspects of impact of advance care planning (ACP) in palliative care and to reflect on further implications on practice and research in the future.

RECENT FINDINGS

Evidence about various ACP impacts is rapidly growing and most common outcome measures are still advance directive completion, change in hospital admission rate and patients' and families' views and experiences with ACP. Mainly descriptive studies bring new information of ACP impact for specific groups of patients, their families, settings, countries, contexts, staff and healthcare system as such. It is not yet clear who and when would best conduct ACP, from general practitioners (GPs) to specialists in the hospitals and even lay-navigators for cancer patients; from early ACP conversations to critical ACP in acute events at the end-of-life. The need for ACP impacts high-quality evidence is becoming more urgent because latest future projections are showing higher palliative care needs than previously expected.

SUMMARY

Recent studies on various ACP impacts reveal variety of outcomes for different patient groups and settings, and are contributing to a wider picture of ACP situation around the world. However, high-quality evidence on ACP impact is still urgently expected in times of growing need for system-level changes for effective ACP implementation.

Social and structural conditions for the avoidance of advance care planning in neuro-oncology: a qualitative study

BACKGROUND

Primary brain tumours newly affect >260 000 people each year worldwide. In the UK, every year >10 000 people are diagnosed with a brain tumour while >5000 die annually from the disease. Prognoses are poor, cognitive deterioration common and patients have prolonged palliative needs. Advance care planning (ACP) may enable early discussion of future care decisions. Although a core commitment in the UK healthcare strategy, and the shared responsibility of clinical teams, ACP appears uncommon in practice. Evidence around ACP practice in neuro-oncology is limited.

OBJECTIVES

We aimed to elicit key social and structural conditions contributing to the avoidance of ACP in neuro-oncology.

DESIGN

A cross-sectional qualitative study design was used.

SETTING

One tertiary care hospital in the UK.

PARTICIPANTS

Fifteen healthcare professionals working in neuro-oncology participated in this study, including neuro-oncologists, neurosurgeons, clinical nurse specialists, allied healthcare professionals and a neurologist.

METHOD

Semi-structured interviews were conducted with participants to explore their assumptions and experiences of ACP. Data were analysed thematically using the well-established framework method.

RESULTS

Participants recognised the importance of ACP but few had ever completed formal ACP documentation. We identified eight key factors, which we suggest comprise three main conditions for avoidance: (1) difficulties being a highly emotive, time-intensive practice requiring the right 'window of opportunity' and (2) presence and availability of others; (3) ambiguities in ACP definition, purpose and practice. Combined, these created a 'culture of shared avoidance'.

CONCLUSION

In busy clinical environments, 'shared responsibility' is interpreted as 'others' responsibility' laying the basis for a culture of avoidance. To address this, we suggest a 'generalists and specialists' model of ACP, wherein healthcare professionals undertake particular responsibilities. Healthcare professionals are already adopting this model informally, but without formalised structure it is likely to fail given a tendency for people to assume a generalist role.
