[THE MULTIDISCIPLINARY GERIATRIC SURGERY UNIT AT THE CHAIM SHEBA MEDICAL CENTER - FIRST YEAR OF ACTIVITY].

INTRODUCTION: Recently, a Geriatric Surgery Unit (GSU) was established in the Sheba Medical Center. The Unit's aims include: professional assessment of surgical candidates, approval of the surgical plan by a multidisciplinary team discussion (MTD), and meeting the specific needs of the geriatric patient undergoing surgery. METHODS: We describe the establishment of the GSU and preliminary results from the first year of its activity (January-December 2022). The GSU team consisted of a geriatric nurse practitioner (NP), a geriatric physician, surgeons, anesthesiologists and a physiotherapist. Inclusion criteria for GSU assessment/treatment were age>80 years or substantial baseline geriatric morbidity. RESULTS: In 2022, 276 patients were treated by the GSU: 110 underwent elective comprehensive preoperative assessment in the NP clinic and the rest were assessed urgently/semi-electively during their hospitalization. One hundred and fifteen cases (median age 86 (65-98) years) were brought to MTD and considered for elective cholecystectomy (46.1%), colorectal procedures (16.5%), hernia repair (13.9%), hepatobiliary procedures (9.6%) or other surgeries (13.9%); of those, 49 patients (median age 86 (72-98) years) eventually proceeded to surgery, following which the median length of hospital stay (LOS) was 3.5 (1-60) days and the rate of postoperative complications was 46.7%. After discharge, the median duration of follow-up was 2.5 (0-18) months during which 4 patients died. Compared with geriatric patients who underwent cholecystectomy during 2021-2023 without MTD (n=39), in the cases discussed by the MTD, patients (n=17) had a shorter LOS (2.0±0.9 vs. 2.4±2.1 days), less 30-day Emergency Department referrals (12.5% vs. 28.2%) and less 30-day re-admissions (6.2% vs. 15.4%; all p≥0.3). CONCLUSIONS: Geriatric surgical patients require a designated professional approach to meet their unique perioperative needs. The effect of GSUs on perioperative outcomes merits further prospective studies.

[SUCCESSFUL AGING-A MULTI-FUNCTIONAL DIMENSION CONCEPT AN EMPHASIS ON THE END OF LIFE].

INTRODUCTION: The concept of "successful aging" as coined by Rowe and Kahan in the late nineties of the last century, came to describe a period of old age with multi-functional abilities. The functions are physical, cognitive and social, without progressive chronic diseases and without disabilities. There is a change in the concept of successful aging beyond the physical dimension (daily function (ADL) and cognitive function) which is based on objective performance indicators towards subjective indicators based on the patients' feelings and their quality of life. Successful aging moves from the limited bio-physical aspect to an overall view of bio-psycho-socio which means mental-emotional-behavioral aspects, social involvement, and also an element of spirituality and even end-of-life decisions. Successful aging will be measured by objective and subjective measures that include the patient's feelings and experiences. The idea is to include and see in successful aging not only the absence of morbidity and disability as seen by Rowe and Kahan, but to a multidimensional function that includes physical and cognitive, mental and emotional, social and spiritual parameters and a dimension of the end of life in making decisions according to the wishes and preferences of the person himself and his family.

Clinician and Family Caregiver Perspectives on Deprescribing Chronic Disease Medications in Older Nursing Home Residents Near the End of Life.

INTRODUCTION: Nursing home (NH) residents with limited life expectancy (LLE) who are intensely treated for hyperlipidemia, hypertension, or diabetes may benefit from deprescribing. OBJECTIVE: This study sought to describe NH clinician and family caregiver perspectives on key influences on deprescribing decisions for chronic disease medications in NH residents near the end of life. METHODS: We recruited family caregivers of veterans who recently died in a Veterans Affairs (VA) NH, known as community living centers (CLCs), and CLC healthcare clinicians (physicians, nurse practitioners, physician assistants, pharmacists, registered nurses). Respondents completed semi-structured interviews about their experiences with deprescribing statin, antihypertensive, and antidiabetic medications for residents near end of life. We conducted thematic analysis of interview transcripts to identify key themes regarding influences on deprescribing decisions. RESULTS: Thirteen family caregivers and 13 clinicians completed interviews. Key themes included (1) clinicians and caregivers both prefer to minimize drug burden; (2) clinical factors strongly influence deprescribing of chronic disease medications, with differences in how clinicians and caregivers weigh specific factors; (3) caregivers trust and rely on clinicians to make deprescribing decisions; (4) clinicians perceive caregiver involvement and buy-in as essential to deprescribing decisions, which requires time and effort to obtain; and (5) clinicians perceive conflicting care from other clinicians as a barrier to deprescribing. CONCLUSIONS: Findings suggest a need for efforts to encourage communication with and education for family caregivers of residents with LLE about deprescribing, and to foster better collaboration among clinicians in CLC and non-CLC settings.

Primary palliative care in the ICU.

ABSTRACT: Despite the best efforts of modern health care and critical care providers, many patients in the intensive care unit (ICU) will still die each year. The need for palliative care services in the ICU is common. Although specialty palliative care services provide excellent care and are a tremendous resource, every critical care provider should be able to provide the basics of palliative care themselves through the model of primary palliative care. Although it may be uncomfortable for the critical care provider at first, providing palliative care to our ICU patients can be a very rewarding experience. In this article, I discuss best practices for handling difficult conversations with patients and their families, helping patients and families make difficult decisions regarding the goals of care, and managing symptoms at the end of life.

[Palliative care in paediatric oncology - a national parental perspective]. / Palliativ vård av barn med cancer.

The WHO definition of paediatric palliative care (PPC) emphasises the role of active multidimensional care, carried out with interdisciplinary competence, and providing support to the entire family. The aim of the current national study was to investigate whether parents perceived that their child received palliative care (PC) before the child died of cancer and the parent's view of the care during the child's last month of life. In 2016, parents (n=226) completed a study-specific survey, and a majority reported that their child had received PC with good professional competence. However, many parents reported that the child was greatly affected by pain in the last month of life. Geographical differences indicated that parents who live in sparsely populated areas to a lesser extent reported that their child received PC. Lastly, our conclusion is that access to equal PPC and improved symptom control is crucial for children and their families.

Primary care usage at the end of life: a retrospective cohort study of cancer patients using linked primary and hospital care data.

PURPOSE: Health service use is most intensive in the final year of a person's life, with 80% of this expenditure occurring in hospital. Close involvement of primary care services has been promoted to enhance quality end-of-life care that is appropriate to the needs of patients. However, the relationship between primary care involvement and patients' use of hospital care is not well described. This study aims to examine primary care use in the last year of life for cancer patients and its relationship to hospital usage. METHODS: Retrospective cohort study in Victoria, Australia, using linked routine care data from primary care, hospital and death certificates. Patients were included who died related to cancer between 2008 and 2017. RESULTS: A total of 758 patients were included, of whom 88% (n = 667) visited primary care during the last 6 months (median 9.1 consultations). In the last month of life, 45% of patients were prescribed opioids, and 3% had imaging requested. Patients who received home visits (13%) or anticipatory medications (15%) had less than half the median bed days in the last 3 months (4 vs 9 days, p < 0.001, 5 vs 10 days, p = 0.001) and 1 month of life (0 vs 2 days, p = 0.002, 0 vs 3 days, p < 0.001), and reduced emergency department presentations (32% vs 46%, p = 0.006, 31% vs 47% p < 0.001) in the final month. CONCLUSION: This study identifies two important primary care processes-home visits and anticipatory medication-associated with reduced hospital usage and intervention at the end of life.

Anticipatory prescribing of injectable controlled drugs (ICDs) in care homes: a qualitative observational study of staff role, uncertain dying and hospital transfer at the end-of-life.

BACKGROUND: The anticipatory prescribing of injectable controlled drugs (ICDs) by general practitioners (GPs) to care home residents is common practice and is believed to reduce emergency hospital transfers at the end-of-life. However, evidence about the process of ICD prescribing and how it affects residents' hospital transfer is limited. The study examined how care home nurses and senior carers (senior staff) describe their role in ICDs prescribing and identify that role to affect residents' hospital transfers at the end-of-life. METHODS: 1,440 h of participant observation in five care homes in England between May 2019 and March 2020. Semi-structured interviews with a range of staff. Interviews (n = 25) and fieldnotes (2,761 handwritten A5 pages) were analysed thematically. RESULTS: Senior staff request GPs to prescribe ICDs ahead of residents' expected death and review prescribed ICDs for as long as residents survive. Senior staff use this mechanism to ascertain the clinical appropriateness of withholding potentially life-extending emergency care (which usually led to hospital transfer) and demonstrate safe care provision to GPs certifying the medical cause of death. This enables senior staff to facilitate a care home death for residents experiencing uncertain dying trajectories. CONCLUSION: Senior staff use GPs' prescriptions and reviews of ICDs to pre-empt hospital transfers at the end-of-life. Policy should indicate a clear timeframe for ICD review to make hospital transfer avoidance less reliant on trust between senior staff and GPs. The timeframe should match the period before death allowing GPs to certify death without triggering a Coroner's referral.

The relationship between the significant loss of a lovedone and alcoholism has minimized the implications oncoping mechanisms to generate healthy behaviors. Thisarticle is based on in-depth semi-structured interviews withmen between the ages of 30 and 70, with more than 10years in Alcoholics Anonymous in the State of Tamaulipas,Mexico. The objective was to reflect on the meanings of the significant loss of a loved one and alcoholism. In thesearch for meaning, it is explained that a factor that leadsto alcoholism is not a single significant loss of loved ones,but also an accumulation of material and non-materiallosses, limited resources were reflected to face the losses,the relationship between the loss significant with alcoholismwas mediated by two main aspects, beliefs about the effectsthat alcohol consumption produces as ways of escapingfrom reality and the influence of the family at the beginningof alcohol consumption. On the other hand, the presenceof the spiritual, the conscience and the emotions that theyexperience during their mourning process and alcoholism,led them to identify the problem of addiction, which allowedthem to influence the rehabilitation process.(AU)

Cuidando al final de la vida. Un programa de intervención online para familiares de pacientes oncológicos en fase paliativa / Caring the caregivers. An online psychological intervention for family caregivers of oncological palliative patients

Resumen: Objetivo: Analizar la eficacia de un programa de intervención psicológica grupal en formato online diseñado para reducir la sobrecarga y el malestar emocional de los cuidadores informales de pacientes oncológicos en fase final de vida. Método: El programa se desarrolló para cuidadores principales de pacientes oncológicos en situación de enfermedad avanzada, con pronóstico de vida inferior a 6 meses. La intervención consistió en cuatro sesiones semanales. Los instrumentos de evaluación fueron la Escala de Detección de Malestar Emocional del Cuidador Principal y la Escala Zarit Reducida y se aplicaron al inicio y al final del programa. Además, se categorizaron las principales preocupaciones de los cuidadores a través de la Escala de Detección del Malestar del Cuidador Principal. Se utilizaron estadísticos descriptivos y t de Student. Resultados: En el estudio participaron 38 familiares de los cuales el 81,6% eran mujeres. En cuanto el grado de parentesco, el 44,7% eran descendientes del paciente. El malestar emocional se redujo significativamente después de la intervención. La incertidumbre se mantuvo como principal preocupación en ambos momentos de medida. Antes del programa, la segunda preocupación más frecuente fue el sufrimiento por el ser querido enfermo, mientras que después de la intervención fue la preocupación por el sufrimiento de otros miembros de la familia. Conclusiones: La realización de este programa de intervención psicológica grupal online demostró ser efectiva para reducir el malestar emocional en los cuidadores principales de pacientes oncológicos al final de la vida. La incertidumbre fue una preocupación constante a lo largo del programa en los familiares. (AU)

Abstract:Aim: analyze the effectiveness of an online delivered psychological intervention program for oncological palliative caregivers in order to reduce the distress and caregiver burden. Methods: The program was developed for primary caregivers of advanced cancer patients, with a life expectancy of less than 6 months. The intervention consisted of 4 weekly sessions. The assessment instruments were the Caregiver Emotional Distress Detection Scale and the Zarit’s Reduced Scale and were applied at the beginning and end of the program. In addition, the main worries of the caregivers were categorized by the Caregiver Emotional Distress Detection Scale. Descriptive statistics and Student’s t were used. Results: 38 caregivers enrolled in intervention, 81.6% of whom were women. Regarding the degree of kinship, 44.7% were descendants of the patient. The distress was significantly reduced after the intervention. Uncertainty remained the main worry at both moments of measurement. Before the program, the second most frequent worry was the suffering of the patient, while after the intervention it was worries about the suffering of other family members. Conclusions: Carrying out this online group psychological intervention program proved to be effective in reducing emotional distress in the main caregivers of cancer patients at the end of life. Uncertainty was a constant concern throughout the program in the relatives. (AU)

Aldosterone levels do not predict 28-day mortality in patients treated for COVID-19 in the intensive care unit.

The immunotropic effects of aldosterone might play a role in COVID-19, as SARS-CoV-2 reportedly uses angiotensin-converting enzyme 2 receptors as an entry point into cells. Aldosterone function is closely linked to its action on mineralocorticoid receptors in kidneys; it increases the renal retention of sodium and the excretion of potassium, which increases blood pressure. Despite the large number of studies examining the effect of Ang-II and its blockers on the course of COVID-19 infection, there is still uncertainty about the role of aldosterone. The aim of the study was to assess the correlation of aldosterone, urea, creatinine, C-reactive protein (CRP), and procalcitonin (PCT) levels with 28 days of mortality in patients treated for COVID19 in an intensive care unit (ICU). This cross-selection study involved 115 adult patients who were divided into two groups: those who died within a 28-day period (n = 82) and those who survived (n = 33). The correlation of aldosterone, urea, creatinine, C-reactive protein (CRP), and procalcitonin (PCT) levels with 28 days of mortality in patients treated for COVID-19 were performed. The patients' age, sex, scores from the APACHE II, SAPS II, and SOFA scales and comorbidities like HA, IHD and DM were also analyzed. Remarkably, the individuals who survived for 28 days were of significantly lower mean age and achieved notably lower scores on the APACHE II, SAPS II, and SOFA assessment scales. Statistically significantly higher CRP levels were observed on days 3, 5, and 7 in individuals who survived for 28 days. Creatinine levels in the same group were also statistically significantly lower on days 1, 3, and 5 than those of individuals who died within 28 days. The investigation employed both univariate and multivariate Cox proportional hazard regression models to explore factors related to mortality. In the univariate analysis, variables with a p value of less than 0.50 were included in the multivariate model. Age, APACHE II, SAPS II, and SOFA demonstrated significance in univariate analysis and were considered to be associated with mortality. The outcomes of the multivariate analysis indicated that age (HR = 1.03, p = 0.033) served as a robust predictor of mortality in the entire study population. In conclusion the plasma aldosterone level is not associated with ICU mortality in patients with COVID-19. Other factors, including the patient's age, creatinine or CRP contribute to the severity and prognosis of the disease. This study was retrospectively registered in the Australian New Zealand Clinical Trials Registry (ANZCTR) with registration no. ACTRN12621001300864 (27/09/2021: https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=382563&isReview=true ).

End-of-life care in Germany between 2016 and 2020 - A repeated cross-sectional analysis of statutory health insurance data.

BACKGROUND: The Hospice and Palliative Care Act of 2015 aimed at developing and regulating the provision of palliative care (PC) services in Germany. As a result of the legal changes, people with incurable diseases should be enabled to experience their final stage of life including death according to their own wishes. However, it remains unknown whether the act has impacted end-of-life care (EoLC) in Germany. OBJECTIVE: The present study examined trends in EoLC indicators for patients who died between 2016 and 2020, in the context of Lower Saxony, Germany. METHODS: Repeated cross-sectional analysis was conducted on data from the statutory health insurance fund AOK Lower Saxony (AOK-LS), referring to the years 2016-2020. EoLC indicators were: (1) the number of patients receiving any form of outpatient PC, (2) the number of patients receiving generalist outpatient PC and (3) specialist outpatient PC in the last year of life, (4) the onset of generalist outpatient PC and (5) the onset of specialist outpatient PC before death, (6) the number of hospitalisations in the 6 months prior to death and (7) the number of days spent in hospital in the 6 months prior to death. Data for each year were analysed descriptively and a comparison between 2016 and 2020 was carried out using t-tests and chi-square tests. RESULTS: Data from 160,927 deceased AOK-LS members were analysed. The number of patients receiving outpatient PC remained almost consistent over time (2016 vs. 2020 p = .077). The number of patients receiving generalist outpatient PC decreased from 28.4% (2016) to 24.5% (2020; p < .001), whereas the number of patients receiving specialist outpatient PC increased from 8.5% (2016) to 11.2% (2020; p < .001). The onset of generalist outpatient PC moved from 106 (2016) to 93 days (2020; p < .001) before death, on average. The onset of specialist outpatient PC showed the reverse pattern (2016: 55 days before death; 2020: 59 days before death; p = .041). CONCLUSION: Despite growing needs for PC at the end of life, the number of patients receiving outpatient PC did not increase between 2016 and 2020. Furthermore, specialist outpatient PC is being increasingly prescribed over generalist outpatient PC. Although the early initiation of outpatient PC has been proven valuable for the majority of people at the end of life, generalist outpatient PC was not initiated earlier in the disease trajectory over the study period, as was found to be true for specialist outpatient PC. Future studies should seek to determine how existing PC needs can be optimally met within the outpatient sector and identify factors that can support the earlier initiation of especially generalist outpatient PC. TRIAL REGISTRATION: The study "Optimal Care at the End of Life" was registered in the German Clinical Trials Register (DRKS00015108; 22 January 2019).

Noninvasive monitoring technologies to identify discomfort and distressing symptoms in persons with limited communication at the end of life: a scoping review.

BACKGROUND: Discomfort and distressing symptoms are common at the end of life, while people in this stage are often no longer able to express themselves. Technologies may aid clinicians in detecting and treating these symptoms to improve end-of-life care. This review provides an overview of noninvasive monitoring technologies that may be applied to persons with limited communication at the end of life to identify discomfort. METHODS: A systematic search was performed in nine databases, and experts were consulted. Manuscripts were included if they were written in English, Dutch, German, French, Japanese or Chinese, if the monitoring technology measured discomfort or distressing symptoms, was noninvasive, could be continuously administered for 4 hours and was potentially applicable for bed-ridden people. The screening was performed by two researchers independently. Information about the technology, its clinimetrics (validity, reliability, sensitivity, specificity, responsiveness), acceptability, and feasibility were extracted. RESULTS: Of the 3,414 identified manuscripts, 229 met the eligibility criteria. A variety of monitoring technologies were identified, including actigraphy, brain activity monitoring, electrocardiography, electrodermal activity monitoring, surface electromyography, incontinence sensors, multimodal systems, and noncontact monitoring systems. The main indicators of discomfort monitored by these technologies were sleep, level of consciousness, risk of pressure ulcers, urinary incontinence, agitation, and pain. For the end-of-life phase, brain activity monitors could be helpful and acceptable to monitor the level of consciousness during palliative sedation. However, no manuscripts have reported on the clinimetrics, feasibility, and acceptability of the other technologies for the end-of-life phase. CONCLUSIONS: Noninvasive monitoring technologies are available to measure common symptoms at the end of life. Future research should evaluate the quality of evidence provided by existing studies and investigate the feasibility, acceptability, and usefulness of these technologies in the end-of-life setting. Guidelines for studies on healthcare technologies should be better implemented and further developed.

Association of filial attitude, filial behavior and death literacy: implications for development of death system in Guangdong-Hong Kong-Macao Greater Bay Area of China.

BACKGROUND: Filial piety, as a major traditional norm in Chinese culture and in Chinese families, affects the attitudes and behaviors of adult children toward their parents and impacts their end-of-life decision-making and the quality of death of their parents. Death literacy is a novel concept aimed at promoting palliative care in the context of public health. AIMS: To understand attitudes and behaviors related to filial piety and to examine the role of death literacy in filial behaviors toward dying parents among residents in the Guangdong-Hong Kong-Macao Greater Bay Area of China. METHODS: A cross-sectional online survey that employed the convenient and snowball sampling methods was adopted. Filial Piety Representations at Parents' End of Life Scale and Death Literacy Index were used. RESULTS: This study identified a significant gap between the filial piety attitudes and behaviors of Chinese adult children. Gender, caregiving experience and death literacy were predictors of filial behaviors in an end-of-life context. CONCLUSION: Providing truth disclosure support, offering guidance to young adult children and caregivers of terminally ill fathers, and strengthening factual and community knowledge of death are necessary to enhance the reciprocal comfort of both adult children and dying parents in the context of Chinese filiality.

Risk Factors for the Mortality of Patients With Coronavirus Disease 2019 Requiring Extracorporeal Membrane Oxygenation in a Non-Centralized Setting: A Nationwide Study.

BACKGROUND: Limited data are available on the mortality rates of patients receiving extracorporeal membrane oxygenation (ECMO) support for coronavirus disease 2019 (COVID-19). We aimed to analyze the relationship between COVID-19 and clinical outcomes for patients receiving ECMO. METHODS: We retrospectively investigated patients with COVID-19 pneumonia requiring ECMO in 19 hospitals across Korea from January 1, 2020 to August 31, 2021. The primary outcome was the 90-day mortality after ECMO initiation. We performed multivariate analysis using a logistic regression model to estimate the odds ratio (OR) of 90-day mortality. Survival differences were analyzed using the Kaplan-Meier (KM) method. RESULTS: Of 127 patients with COVID-19 pneumonia who received ECMO, 70 patients (55.1%) died within 90 days of ECMO initiation. The median age was 64 years, and 63% of patients were male. The incidence of ECMO was increased with age but was decreased after 70 years of age. However, the survival rate was decreased linearly with age. In multivariate analysis, age (OR, 1.048; 95% confidence interval [CI], 1.010-1.089; P = 0.014) and receipt of continuous renal replacement therapy (CRRT) (OR, 3.069; 95% CI, 1.312-7.180; P = 0.010) were significantly associated with an increased risk of 90-day mortality. KM curves showed significant differences in survival between groups according to age (65 years) (log-rank P = 0.021) and receipt of CRRT (log-rank P = 0.004). CONCLUSION: Older age and receipt of CRRT were associated with higher mortality rates among patients with COVID-19 who received ECMO.

Life Cycle of Functional All-Green Biocompatible Fibrous Materials Based on Biodegradable Polyhydroxybutyrate and Hemin: Synthesis, Service Life, and the End-of-Life via Biodegradation.

This article addresses the entire life cycle of the all-green fibrous materials based on poly(3-hydroxybutyrate) (PHB) containing a natural biocompatible additive Hemin (Hmi): from preparation, service life, and the end of life upon in-soil biodegradation. Fibrous PHB/Hmi materials with a highly developed surface and interconnected porosity were prepared by electrospinning (ES) from Hmi-containing feed solutions. Structural organization of the PHB/Hmi materials (porosity, uniform structure, diameter of fibers, surface area, distribution of Hmi within the PHB matrix, phase composition, etc.) is shown to be governed by the ES conditions: the presence of even minor amounts of Hmi in the PHB/Hmi (below 5 wt %) serves as a powerful tool for the control over their structure, performance, and biodegradation. Service characteristics of the PHB/Hmi materials (wettability, prolonged release of Hmi, antibacterial activity, breathability, and mechanical properties) were studied by different physicochemical methods (scanning electron microscopy, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, differential scanning calorimetry, contact angle measurements, antibacterial tests, etc.). The effect of the structural organization of the PHB/Hmi materials on their in-soil biodegradation at the end of life was analyzed, and key factors providing efficient biodegradation of the PHB/Hmi materials at all stages (from adaptation to mineralization) are highlighted (high surface area and porosity, thin fibers, release of Hmi, etc.). The proposed approach allows for target-oriented preparation and structural design of the functional PHB/Hmi nonwovens when their structural supramolecular organization with a highly developed surface area controls both their service properties as efficient antibacterial materials and in-soil biodegradation upon the end of life.
