RESUMO
BACKGROUND: Access to palliative care is often limited for challenging and vulnerable groups, including persons with substance use disorders. However, with optimized healthcare options and liberal substitution policies, this patient group is likely to increase over the upcoming years, and comorbidities will also influence the need for palliative support. Here, we aim at analyzing characteristics and specific challenges associated with substance use disorders (SUD) in palliative care. METHODS: We retrospectively reviewed all patients diagnosed with substance use disorder that were treated at our Competence Center Palliative Care within the University Hospital Zurich, Switzerland between 2015 and 2021. Patient characteristics, including age, gender, duration of hospitalization, as well as specific metrics like body mass index, distinct palliative care assessment scores, and in-hospital opioid consumption were retrieved from the electronic patient files. Demographics and clinical data were analyzed by descriptive statistics, and compared to those of a control group of palliative care patients without SUD. An opioid calculator was used to standardize opioid intake based on morphine equivalents for meaningful comparisons. RESULTS: The primary characteristics revealed that the majority of individuals were single (56%), had no children (83%), lived alone (39%), and were either unemployed or recipients of a disability pension (in total 50%). Nicotine (89%), opioids (67%), and alcohol (67%) were the most used substances. We identified various comorbidities including psychiatric illnesses alongside SUD (56%), hepatitis A, B, or C (33%), and HIV infection (17%). Patients with SUD were significantly younger (p < 0.5), predominantly male (p < 0.05), and reported a higher prevalence of pain (p < 0.5) compared to the standard cohort of palliative patients. Regarding the challenges most frequently reported by healthcare practitioners, non-compliance, multimorbidity, challenging communication, biographical trauma, lack of social support, and unstable housing situations played a key role. CONCLUSION: Patients with SUD represent a complex and vulnerable group dealing with multiple comorbidities that profoundly affect both their physical and psychological well-being. Understanding their unique characteristics is pivotal in providing precise and suitable palliative care.

BACKGROUND: This study extended the original Dignity Therapy (DT) intervention by including partners and family caregivers (FCs) of terminally-ill cancer patients with the overall aim of evaluating whether DT can mitigate distress in both patients nearing the end of life and their FCs. METHODS: In this multicenter, randomized controlled trial (RCT), a total of 68 patients with life expectancy < 6 months and clinically-relevant stress levels (Hospital Anxiety Depression total score; HADStot ≥ 8) including their FCs were randomly assigned to DT, DT + (including their FCs), or standard palliative care (SPC) in a 1:1:1 ratio. Study participants were asked to complete a set of questionnaires pre- and post-intervention. RESULTS: The coalesced group (DT and DT +) revealed a significant increase in patients' perceived quality of life (FACIT-Pal-14) following the intervention (mean difference 6.15, SD = 1.86, p < 0.01). We found a statistically significant group-by-time interaction effect: while the HADStot of patients in the intervention group remained stable over the pre-post period, the control group's HADStot increased (F = 4.33, df = 1, 82.9; p < 0.05), indicating a protective effect of DT. Most patients and their FCs found DT useful and would recommend it to other individuals in their situation. CONCLUSIONS: The DT intervention has been well-received and shows the potential to increase HRQoL and prevent further mental health deterioration, illness burden and suffering in terminally-ill patients. The DT intervention holds the potential to serve as a valuable tool for facilitating end-of-life conversations among terminally-ill patients and their FCs. However, the implementation of DT within the framework of a RCT in a palliative care setting poses significant challenges. We suggest a slightly modified and less resource-intensive version of DT that is to provide the DT inventory to FCs of terminally-ill patients, empowering them to ask the questions that matter most to them over their loved one's final days. TRIAL REGISTRATION: This study was registered with Clinical Trial Registry (ClinicalTrials.gov -Protocol Record NCT02646527; date of registration: 04/01/2016). The CONSORT 2010 guidelines were used for properly reporting how the randomized trial was conducted.

BACKGROUND AND INTRODUCTION: The place of last care carries importance for patients at the end of life. It is influenced by the realities of the social welfare and healthcare systems, cultural aspects, and symptom burden. This study aims to investigate the place of care trajectories of patients admitted to an acute palliative care unit. MATERIALS AND METHODS: The medical records of all patients hospitalized on our acute palliative care unit in 2019 were assessed. Demographic, socio-economic and disease characteristics were recorded. Descriptive and inferential statistics were used to identify determinants for place of last care. RESULTS: A total of 377 patients were included in this study. Median age was 71 (IQR, 59-81) years. Of these patients, 56% (n = 210) were male. The majority of patients was Swiss (80%; n = 300); about 60% (n = 226) reported a Christian confession; and 77% had completed high school or tertiary education. Most patients (80%, n = 300) had a cancer diagnosis. The acute palliative care unit was the place of last care for 54% of patients. Gender, nationality, religion, health insurance, and highest level of completed education were no predictors for place of last care, yet previous outpatient palliative care involvement decreased the odds of dying in a hospital (OR, 0.301; 95% CI, 0.180-0.505; p-value < 0.001). CONCLUSION: More than half of patients admitted for end-of-life care died on the acute palliative care unit. While socio-economic factors did not determine place of last care, previous involvement of outpatient palliative care is a lever to facilitate dying at home.

Pro-tumorigenic electrochemical synapses between neurons and brain tumour cells in preclinical studies suggest unfavourable effects of epilepsy on patient survival. We investigated associations of epilepsy and survival in three cohorts of brain tumour patients (meningioma, glioblastoma and brain metastases). Cohorts were segregated into three groups for comparative analyses: (i) no epilepsy; (ii) epilepsy without status epilepticus; and (iii) status epilepticus. Status epilepticus was considered a surrogate of extensive neuronal hyperexcitability. The main outcome was progression-free survival (meningioma) and overall survival (glioblastoma and brain metastases), adjusted for established prognostic factors and onset of epilepsy by time-dependent multivariate Cox modelling. The primary analysis population comprised 1792 patients (742 meningioma, 249 glioblastoma, 801 brain metastases). Epilepsy was associated with favourable prognostic factors. However, on multivariate analyses, status epilepticus was associated with inferior overall survival of patients with glioblastoma [status epilepticus versus no epilepsy multivariate hazard ratio (HR) 3.72, confidence interval (CI) 1.78-7.76, P < 0.001] and brain metastases (status epilepticus versus no epilepsy HR 2.30, CI 1.10-4.79, P = 0.026). Among brain metastases patients, but not among patients with meningioma or glioblastoma, epilepsy was similarly associated with inferior overall survival (epilepsy versus no epilepsy HR 2.16, CI 1.60-2.93, P < 0.001). We conclude that epilepsy may convey inferior survival of patients with malignant brain tumours.

PURPOSE: Accurate prediction of survival is important to facilitate clinical decision-making and improve quality of care at the end of life. While it is well documented that survival prediction poses a challenge for treating physicians, the need for clinically valuable predictive factors has not been met. This study aims to quantify the prevalence of patient transfer 72 h before death onto the acute palliative care unit in a tertiary care center in Switzerland, and to identify factors predictive of 72-h mortality. METHODS: All patients hospitalized between January and December 2020 on the acute palliative care unit of the Competence Center Palliative Care of the Department of Radiation Oncology at the University Hospital Zurich were assessed. Variables were retrieved from the electronic medical records. Univariable and multivariable logistic regressions were used to identify predictors of mortality. RESULTS: A total of 398 patients were screened, of which 188 were assessed. Every fifth patient spent less than 72 h on the acute palliative care unit before death. In multivariable logistic regression analysis, predictors for 72-h mortality after transfer were no prior palliative care consult (p = 0.011), no advance care directive (p = 0.044), lower performance status (p = 0.035), lower self-care index (p = 0.003), and lower blood albumin level (p = 0.026). CONCLUSION: Late transfer to the acute palliative care unit is not uncommon, which can cause additional distress to patients and caretakers. Though clinically practical short-term survival predictors remain largely unidentified, early integration of palliative care should be practiced more regularly in patients with life-limiting illness.

OBJECTIVES: Patients with terminal illness are at high risk of developing delirium, in particular, those with multiple predisposing and precipitating risk factors. Delirium in palliative care is largely under-researched, and few studies have systematically assessed key aspects of delirium in elderly, palliative-care patients. METHODS: In this prospective, observational cohort study at a tertiary care center, 229 delirious palliative-care patients stratified by age: <65 (N = 105) and ≥65 years (N = 124), were analyzed with logistic regression models to identify associations with respect to predisposing and precipitating factors. RESULTS: In 88% of the patients, the underlying diagnosis was cancer. Mortality rate and median time to death did not differ significantly between the two age groups. No inter-group differences were detected with respect to gender, care requirements, length of hospital stay, or medical costs. In patients ≥65 years, exclusively predisposing factors were relevant for delirium, including hearing impairment [odds ratio (OR) 3.64; confidence interval (CI) 1.90-6.99; P < 0.001], hypertension (OR 3.57; CI 1.84-6.92; P < 0.001), and chronic kidney disease (OR 4.84; CI 1.19-19.72; P = 0.028). In contrast, in patients <65 years, only precipitating factors were relevant for delirium, including cerebral edema (OR 0.02; CI 0.01-0.43; P = 0.012). SIGNIFICANCE OF RESULTS: The results of this study demonstrate that death in delirious palliative-care patients occurs irrespective of age. The multifactorial nature and adverse outcomes of delirium across all age in these patients require clinical recognition. Potentially reversible factors should be detected early to prevent or mitigate delirium and its poor survival outcomes.

OBJECTIVE: Delirium is a frequent complication in advanced cancer patients, among whom it is frequently underdiagnosed and inadequately treated. To date, evidence on risk factors and the prognostic impact of delirium on outcomes remains sparse in this patient population. METHOD: In this prospective observational cohort study at a single tertiary-care center, 1,350 cancer patients were enrolled. Simple and multiple logistic regression models were utilized to identify associations between predisposing and precipitating factors and delirium. Cox proportional-hazards models were used to estimate the effect of delirium on death rate. RESULTS: In our patient cohort, the prevalence of delirium was 34.3%. Delirium was associated inter alia with prolonged hospitalization, a doubling of care requirements, increased healthcare costs, increased need for institutionalization (OR 3.22), and increased mortality (OR 8.78). Predisposing factors for delirium were impaired activity (OR 10.82), frailty (OR 4.75); hearing (OR 2.23) and visual impairment (OR 1.89), chronic pneumonitis (OR 2.62), hypertension (OR 1.46), and renal insufficiency (OR 1.82). Precipitating factors were acute renal failure (OR 7.50), pressure sores (OR 3.78), pain (OR 2.86), and cystitis (OR 1.32). On multivariate Cox regression, delirium increased the mortality risk sixfold (HR 5.66). Age ≥ 65 years and comorbidities further doubled the mortality risk of delirious patients (HR 1.77; HR 2.05). SIGNIFICANCE OF RESULTS: Delirium is common in cancer patients and associated with increased morbidity and mortality. Systematically categorizing predisposing and precipitating factors might yield new strategies for preventing and managing delirium in cancer patients.

PURPOSE: Little is known about efficacy and toxicity of radiation therapy in the elderly, as the vast majority of prospective trials excluded patients aged over 70 years. The aim of this study was to investigate the outcome of radiation therapy in a group of so-called oldest old cancer patients (≥85 years). MATERIALS AND METHODS: We retrospectively reviewed data from patients aged ≥85 years, treated between 2010 and 2015 for any tumor histology at the University Hospital Zurich, Switzerland. Overall survival (OS), relapse-free survival (RFS), performance status (ECOG), Charlson comorbidity index (CCI) and treatment tolerance were assessed. RESULTS: We identified and included 100 patients with a mean age of 88 years (range: 85-102 years). Most patients received a curative-intent treatment (nâ¯= 64, 64%). About one third received palliative radiation therapy for symptomatic metastatic disease (nâ¯= 36, 36%). Curative treatment was well tolerated, with no high-grade acute toxicities (≥grade 4). Median OS was 52.6 and 13.1 months for the curative and palliative treated patient groups, respectively. 5year OS for all patients was 39.5% (95% CI: 23.6-54.5%). The Charlson comorbidity index (CCI) had a predictive value for overall survival (CCIâ¯> 10, pâ¯= 0.0001) in the curative group. CONCLUSION: The number of older cancer patients will increase considerably in the next decades because of demographic changes. Our analysis supports the notion that radiation therapy for this patient group of oldest old cancer patients is feasible in general. Treatment decisions should not be based on chronological age but rather on comorbidities and functional status.

PURPOSE: Gliomas are primary brain tumors with a life-limiting course of disease, and the last weeks of life are often characterized by neurological deficits that affect communication and personality. End-of-life treatment in this patient group therefore requires specific approaches. To date, little data is available on patients' and caregivers' needs and experiences in the last phase of the disease. METHODS: In this observational study, relatives of patients treated at the University Hospital Zurich, Switzerland and deceased 2015-2017 due to glioma progression were contacted to complete a structured questionnaire assessing caregivers experience within the last weeks of the disease. RESULTS: The survey was sent to 120 relatives of deceased patients with a glioma (WHO grades II-IV) (median patient age: 62 years; 73.8% male). Forty-three questionnaires were returned (37.7%). Approximately half of the patients were taken care of at home in the last 4 weeks of the disease, mainly with the assistance of in-home nursing care, of which eventually 14 patients (63.6%) died at home. While caregivers reported high satisfaction with medical and nursing care, psychological support was rated average to poor on a 10-point scale. Free comment fields were used widely, revealing open questions and needs of the relatives. CONCLUSIONS: This study illustrates the need for a more patient-centered end-of-life care including higher psychological support mechanisms, and a higher inclusion and consideration of relatives and caregivers into the care focus. Earlier discussion of end-of-life preferences could prevent hospitalizations in the last phase of life and could improve patients' and caregivers' quality of life.

OBJECTIVE: Delirium is a common complication in palliative care patients, especially in the terminal phase of the illness. To date, evidence regarding risk factors and prognostic outcomes of delirium in this vulnerable population remains sparse. METHOD: In this prospective observational cohort study at a tertiary care center, 410 palliative care patients were included. Simple and multiple logistic regression models were used to identify associations between predisposing and precipitating factors and delirium in palliative care patients. RESULTS: The prevalence of delirium in this palliative care cohort was 55.9% and reached 93% in the terminally ill. Delirium was associated with prolonged hospitalization (p < 0.001), increased care requirements (p < 0.001) and health care costs (p < 0.001), requirement for institutionalization (OR 0.11; CI 0.069-0.171; p < 0.001), and increased mortality (OR 18.29; CI 8.918-37.530; p < 0.001). Predisposing factors for delirium were male gender (OR 2.19; CI 1.251-3.841; p < 0.01), frailty (OR 15.28; CI 5.885-39.665; p < 0.001), hearing (OR 3.52; CI 1.721-7.210; p < 0.001), visual impairment (OR 3.15; CI 1.765-5.607; p < 0.001), and neoplastic brain disease (OR 3.63; CI 1.033-12.771; p < 0.05). Precipitating factors for delirium were acute renal failure (OR 6.79; CI 1.062-43.405; p < 0.05) and pressure sores (OR 3.66; CI 1.102-12.149; p < 0.05). SIGNIFICANCE OF RESULTS: Our study identified several predisposing and precipitating risk factors for delirium in palliative care patients, some of which can be targeted early and modified to reduce symptom burden.

Background: The aim is to implement knowledge of basic palliative care in selected departments by the Hub and Spokes model. Methods: Implementation of basic palliative care was designed as a stepwise training model by skills lectures over a time period of 2 years. In each of the six selected oncological and nononcological departments, one physician and two nurses were trained in semi-annual half-day meetings as expert representatives within their departments. Results: Semi-structured interviews were conducted to assess implementation outcomes with 12 nurses and 6 physicians. Overall acceptability was high for all departments and professions. Feasibility was given in all departments. Adoption and penetration of a trained expert representative differed between medical and nursing professions. Implementation was more appropriate in the stationary sector. Implementation costs were low. Conclusion: Expansion of the system into a second follow-up period, including more departments, is planned to ensure sustainability.

Background: The value of early integration of palliative care has been demonstrated increasingly for the past years in both oncological and nononcological diseases. Outpatient palliative care services might represent a feasible approach to implement supportive care in early disease. In this study, we aimed at evaluating which patients use and benefit from outpatient palliative care services, which symptoms are addressed most, and which support services are installed in this early phase of disease. Methods: We retrospectively analyzed the entire patient collective of a recently developed palliative care outpatient clinic within the leading university hospital in Switzerland for a period of five years. Sociodemographics, symptoms, and information on disease as well as patient-reported outcomes were retrieved from the electronic patient files. Demographic and clinical data were analyzed by descriptive statistics between groups and survival was analyzed by means of Kaplan-Meier estimates and log-rank test. Results: We report on 642 consultations of 363 patients between 2016 and 2020. Patients had a mean of 1.8 visits (range 1-10), with n = 340 patients (93.7%) of patients suffering from an oncological disease. Overall symptom load was high, with n = 401 (73.7%) of patient-reported outcomes reporting two or more symptoms. Distress levels of 5 or higher were reported in n = 78 (30.4%) of available patient-reported outcomes. Independent of the origin of primary disease and the length of the disease trajectory, patients were referred to the palliative care service in median only four months before death. Conclusion: We identify high symptom load and distress in the outpatient palliative patient population. Patients benefitted from supportive medication, improvement of ambulatory support systems and advance care planning, and more than one-third of patients remained in follow-up, indicating a good acceptance of the service. Overcoming the overall late referral could, however, further increase the quality of life at earlier stages of disease.
RESUMO
BACKGROUND: The limitation of life sustaining treatments (LLST) causes ethical dilemmas even in patients faced with poor prognosis, which applies to many patients admitted to a Neurocritical Care Unit (NCCU). The effects of social and cultural aspects on LLST in an NCCU population remain poorly studied. METHODS: All NCCU patients between 01.2018 and 08.2021 were included. Medical records were reviewed for: demographics, diagnosis, severity of disease, and outcome. Advance directives (AD) and LLST discussions were reviewed evaluating timing, degree, and reason for LLST. Social/cultural factors (nationality, language spoken, religion, marital status, relationship to/sex of legal representative) were noted. Associations between these factors and the patients' sex, LLST timing, and presence of AD were evaluated. RESULTS: Out of 2975 patients, 12% of men and 10.5% of women underwent LLST (p = 0.30). Women, compared to men, more commonly received withdrawal instead of withholding of life sustaining treatments (57.5 vs. 45.1%, p = 0.028) despite comparable disease severity. Women receiving LLST were older (73 ± 11.7 vs. 69 ± 14.9 years, p = 0.005) and often without a partner (43.8 vs. 25.8%, p = 0.001) compared to men. AD were associated with female sex and early LLST, but not with an increased in-hospital mortality (57.1 vs. 75.2% of patients with and without AD respectively). CONCLUSIONS: In patients receiving LLST, the presence of an AD was associated with an increase of early LLST, but not with an increased in-hospital mortality. This supports the notion that the presence of an AD is primarily an expression of the patients' will but does not per se predestine the patient for an unfavorable outcome.
RESUMO
Background: Digital health technologies have potential to transform palliative care (PC) services. The global aging population poses unique challenges for PC, which digital health technologies may help overcome. Evaluation of attitudes and perceptions combined with quantification of prior use habits favor an understanding of psychological barriers to PC patient acceptance of digital health technologies including artificial intelligence (AI). Objectives: We aimed to evaluate the attitudes and perceptions of PC patients regarding a broad range of digital health technologies used in their routine monitoring and treatment and identify barriers to use. Methods: We used a 39-item questionnaire to evaluate acceptance and use of smartphone-based electronic patient report outcome measures, wearables, AI, data privacy, and virtual reality (VR) in 29 female and male PC inpatients. Results: A majority of patients indicated an interest in (69.0%) and positive attitude toward (75.9%) digital health technologies. Nearly all (93.1%) patients believe that digital health technologies will become more important in medicine in the future. Most patients would consider using their smartphone (79.3%) or wearable (69.0%) more often for their health. The most feasible technologies were smartphones, wearables, and VR. Barriers to acceptance included unfamiliarity, data security, errors in data interpretation, and loss of personal interaction through AI. Conclusion: In this patient survey, acceptance of new technologies in a PC patient population was high, encouraging its use also at the end-of-life.
RESUMO
Introduction and background: While recurrent glioblastoma patients are often treated with re-irradiation, there is limited data on the use of re-irradiation in the setting of bevacizumab (BEV), temozolomide (TMZ) re-challenge, or immune checkpoint inhibition (ICI). We describe target delineation in patients with prior anti-angiogenic therapy, assess safety and efficacy of re-irradiation, and evaluate patterns of recurrence. Materials and methods: Patients with a histologically confirmed diagnosis of glioblastoma treated at a single institution between 2013 and 2021 with re-irradiation were included. Tumor, treatment and clinical data were collected. Logistic and Cox regression analysis were used for statistical analysis. Results: One hundred and seventeen recurrent glioblastoma patients were identified, receiving 129 courses of re-irradiation. In 66 % (85/129) of cases, patients had prior BEV. In the 80 patients (62 %) with available re-irradiation plans, 20 (25 %) had all T2/FLAIR abnormality included in the gross tumor volume (GTV). Median overall survival (OS) for the cohort was 7.3 months, and median progression-free survival (PFS) was 3.6 months. Acute CTCAE grade ≥ 3 toxicity occurred in 8 % of cases. Concurrent use of TMZ or ICI was not associated with improved OS nor PFS. On multivariable analysis, higher KPS was significantly associated with longer OS (p < 0.01). On subgroup analysis, patients with prior BEV had significantly more marginal recurrences than those without (26 % vs. 13 %, p < 0.01). Conclusion: Re-irradiation can be safely employed in recurrent glioblastoma patients. Marginal recurrence was more frequent in patients with prior BEV, suggesting a need to consider more inclusive treatment volumes incorporating T2/FLAIR abnormality.
RESUMO
Objective: To summarize the available literature on using machine learning (ML) for palliative care practice as well as research and to assess the adherence of the published studies to the most important ML best practices. Methods: The MEDLINE database was searched for the use of ML in palliative care practice or research, and the records were screened according to PRISMA guidelines. Results: In total, 22 publications using machine learning for mortality prediction (n = 15), data annotation (n = 5), predicting morbidity under palliative therapy (n = 1), and predicting response to palliative therapy (n = 1) were included. Publications used a variety of supervised or unsupervised models, but mostly tree-based classifiers and neural networks. Two publications had code uploaded to a public repository, and one publication uploaded the dataset. Conclusions: Machine learning in palliative care is mainly used to predict mortality. Similarly to other applications of ML, external test sets and prospective validations are the exception.
RESUMO
AbstractGlioma patients carry the burden of having both a progressive neurological disease and cancer, and may face a variety of symptoms, including depression and anxiety. These symptoms are highly prevalent in glioma patients (median point prevalence ranging from 16-41% for depression and 24-48% for anxiety when assessed by self-report questionnaires) and have a major impact on health-related quality of life and even overall survival time. A worse overall survival time for glioma patients with depressive symptoms might be due to tumor progression and/or its supportive treatment causing depressive symptoms, an increased risk of suicide or other (unknown) factors. Much is still unclear about the etiology of depressive and anxiety symptoms in glioma. These psychiatric symptoms often find their cause in a combination of neurophysiological and psychological factors, such as the tumor and/or its treatment. Although these patients have a particular idiosyncrasy, standard treatment guidelines for depressive and anxiety disorders apply, generally recommending psychological and pharmacological treatment. Only a few nonpharmacological trials have been conducted evaluating the efficacy of psychological treatments (eg, a reminiscence therapy-based care program) in this population, which significantly reduced depressive and anxiety symptoms. No pharmacological trials have been conducted in glioma patients specifically. More well-designed trials evaluating the efficacy of nonpharmacological treatments for depressive and anxiety disorders in glioma are urgently needed to successfully treat psychiatric symptoms in brain tumor patients and to improve (health-related) quality of life.
RESUMO
End-of-Life Dreams and Visions Abstract: End-of life dreams and visions (ELDVs) or so-called death bed phenomena are transcendent experiences at the end of life that can be visual, auditory and/or kinesthetic, and often include visions of (deceased) loved ones, close friends or perceptions of places, travels, bright lights, or music. ELDVs typically occur weeks to hours prior to death and may comfort the dying and prepare spiritually for the end of life. Such experiences are frequently reported by dying individuals, the prevalence varying between 30 and 80%, but in the clinical context ELDVs are usually neglected, but interpreted and treated as pathological changes in the brain that result in, and from, delirium. This article tries to enlighten the occurrence, the contents and meanings of ELDVs in dying persons as opposed to delirium and night dreams using findings from the literature and from clinical observations. Implications of these conclusions for palliative care and the therapeutic relevance of ELDVs when taking care of dying individuals and their loved ones will also be discussed.
