Kidney supportive care for advanced chronic and end-stage kidney disease: a retrospective cohort study.

BACKGROUND: Kidney supportive care is an interdisciplinary model of person-centred medicine, suitable for patients with advanced Chronic Kidney Disease (CKD) and with End-Stage Kidney Disease (ESKD). There is little information on routine care, and palliative care remains poorly integrated into standard nephrology care. The aim of this study was to describe our experience in integrating a palliative care approach into the nephrology care of advanced chronic and end-stage kidney disease. METHODS: A retrospective cohort study was conducted from 1 June, 2017 until 31 December, 2020 on 67 advanced CKD and ESKD patients admitted to a palliative care service. RESULTS: The patients' median age was 83.6 years, 62.7% were male, 16.4% had CKD stage 4 and 83.6% stage 5. Almost half (47.8%) of the patients were on kidney replacement therapy, and 52.2% were on conservative therapy. The majority (77.6%) received home-based palliative care, 17.9% hospice care and 4.5% day-hospice care. The median number of nephrologists' visits per patient was 3.5. Access to palliative care specialists was set at 100% and the median number of palliative clinicians' visits was 8. Eighty-five percent of patients did not require hospitalisation and 94% did not access to the emergency room; 86.2% of the patients died in hospice or at home. CONCLUSIONS: This study reports on the first steps taken to change practice in nephrology, by applying the Italian guideline for an integrated pathway of palliative care in nephrology. Nephrologists' and the palliative care team created a multi- and inter-disciplinary team, sharing their professional skills to support patients in hospice or at home.

Development and external validation of a predictive multivariable model for last-weeks survival of advanced cancer patients in the palliative home care setting (PACS).

PURPOSE: Various prognostic indexes have been proposed to improve physicians' ability to predict survival time in advanced cancer patients, admitted to palliative care (PC) with a survival probably to a few weeks of life, but no optimal score has been identified. The study aims therefore to develop and externally validate a new multivariable predictive model in this setting. METHODS: We developed a model to predict short-term overall survival in cancer patients on the basis of clinical factors collected at PC admission. The model was developed on 1020 cancer patients prospectively enrolled to home palliative care at VIDAS Milan, Italy, between May 2018 and February 2020 and followed-up to June 2020, and validated in two separate samples of 544 home care and 247 hospice patients. RESULTS: Among 68 clinical factors considered, five predictors were included in the predictive model, i.e., rattle, heart rate, anorexia, liver failure, and the Karnofsky performance status. Patient's survival probability at 5, 15, 30 and 45 days was estimated. The predictive model showed a good calibration and moderate discrimination (area under the receiver operating characteristic curve between 0.72 and 0.79) in the home care validation set, but model calibration was suboptimal in hospice patients. CONCLUSIONS: The new multivariable predictive model for palliative cancer patients' survival (PACS model) includes clinical parameters routinely at patient's admission to PC and can be easily used to facilitate immediate and appropriate short-term clinical decisions for PC cancer patients in the home setting.

Cognition, function, and prevalent dementia in centenarians and near-centenarians: An individual participant data (IPD) meta-analysis of 18 studies.

INTRODUCTION: There are limited data on prevalence of dementia in centenarians and near-centenarians (C/NC), its determinants, and whether the risk of dementia continues to rise beyond 100. METHODS: Participant-level data were obtained from 18 community-based studies (N = 4427) in 11 countries that included individuals ≥95 years. A harmonization protocol was applied to cognitive and functional impairments, and a meta-analysis was performed. RESULTS: The mean age was 98.3 years (SD = 2.67); 79% were women. After adjusting for age, sex, and education, dementia prevalence was 53.2% in women and 45.5% in men, with risk continuing to increase with age. Education (OR 0.95;0.92-0.98) was protective, as was hypertension (odds ratio [OR] 0.51;0.35-0.74) in five studies. Dementia was not associated with diabetes, vision and hearing impairments, smoking, and body mass index (BMI). DISCUSSION: Among the exceptional old, dementia prevalence remains higher in the older participants. Education was protective against dementia, but other factors for dementia-free survival in C/NC remain to be understood.

Prevalence of Delirium in End-of-Life Palliative Care Patients: An Observational Study.

OBJECTIVES: The aim of this study was to assess the prevalence of delirium, using the Assessment Test for Delirium and Cognitive Impairment (4AT) in end-of-life palliative care patients. SUBJECTS AND METHODS: This retrospective cross-sectional study was conducted on end-of-life patients in a hospice or at home. All patients were evaluated with the 4AT for the presence of delirium. RESULTS: Of the 461 patients analyzed, 76 (16.5%) were inpatients and 83.5% (385) outpatients. The median age was 79.5 (72-86) years, and 51.0% were female. According to the 4AT score, 126 patients (27.3%) had delirium (A4T ≥4) at admission, 28 (36.8%) were inpatients, and 98 (25.5%) outpatients. Around 33.8% of the cancer inpatients had delirium, while 20.6% of the cancer outpatients had delirium. The prevalence of delirium varied according to the setting, clinical condition, and life expectancy. In addition, 55.0% (11) actively dying inpatients, within 3 days, had delirium, and 56.7% (17) outpatients had delirium; while among those with life expectancy longer than 4 days, 30.4% (17) inpatients and 22.8% (81) outpatients were with delirium. CONCLUSIONS: Our study confirms that delirium is common in cancer and noncancer palliative care patients. Further research on delirium in end-of-life palliative care patients should consider the complexity of palliative care of this population as well as of the characteristics of the settings.

Anticholinergic load and delirium in end-of-life patients.

BACKGROUND: Delirium is a neuropsychiatric syndrome associated with negative outcomes, including worsening of cognitive and functional status and an increased burden on patients and caregivers. Medications with anticholinergic effect have been associated with delirium symptoms, but the relationship is still debated. OBJECTIVE: To assess the relation between delirium and anticholinergic load according to the hypothesis that the cumulative anticholinergic burden increases the risk of delirium. METHODS: This retrospective cross-sectional study was conducted in a sample of end-of-life patients in a hospice or living at home between February and August 2019. Delirium was diagnosed on admission using the 4 'A's Test (4AT) and each patient's anticholinergic burden was measured with the Anticholinergic Cognitive Burden (ACB) scale. RESULTS: Of the 461 eligible for analysis, 124 (26.9%) had delirium. Anticholinergic medications were associated with an increased risk of delirium in univariate (OR (95% CI) 1.26 (1.16-1.38), p < 0.0001) and multivariate models adjusted for age, sex, dementia, tumors, Karnofsky Performance Status (KPS) score, days of palliative assistance, and setting (OR (95% CI) 1.16 (1.05-1.28), p < 0.0001). Patients with delirium had a greater anticholinergic burden than those without, with a dose-effect relationship between total ACB score and delirium. Patients who scored 4 or more had 2 or 3 times the risk of delirium than those not taking anticholinergic drugs. The dose-response relationship was maintained in the multivariate model. CONCLUSIONS: Anticholinergic drugs may influence the development of delirium due to the cumulative effect of multiple medications with modest antimuscarinic activity.

Inappropriate medications among end-of-life patients living at home: an Italian observational study.

PURPOSE: To determine the use of avoidable medications in end-of-life patients living at home when they were moved from the general practice setting to the palliative medicine physician (T1) and before death (T2). METHODS: This retrospective longitudinal study describes the prevalence of end-of-life patients cared for at home between April 2016 and December 2018 receiving preventive and symptomatic drug treatments. Socio-demographic data, diagnosis and drug treatments for each patient were collected in a web-based Case Report Form. RESULTS: The study sample comprised 1565 end-of-life patients with a median age (25-75 percentile) of 79.8 (72.5-85.3 years). All patients were treated with symptomatic drugs, and there were significantly fewer patients from T1 to T2 with at least one preventive medication at end of life (92.1% and, 60.8%, p < 0.0001). There was a significant variability between the palliative care physicians in the mean numbers of avoidable preventive medication (1.5-3.9 at T1 and 0.4-2.7 at T2, p = 0.06) prescribed. CONCLUSION: More than half end-of-life patients living at home still receive avoidable medications. Drug prescription needs to be improved and palliative care setting could have an important role in reducing potentially inappropriate prescriptions. Emphasizing the positive aspects of stopping medicines, shared criteria with de-prescribing guidelines for potentially inappropriate medication in end-of-life patients and multidisciplinary discussion with involvement of patient and family caregivers could be useful to rationalize drug therapy.

Incidence of dementia in the oldest-old and its relationship with age: The Monzino 80-plus population-based study.

INTRODUCTION: Relationship between age and dementia at extreme old ages is still an open question, yet population-based studies in this high-risk age segment are rare. METHODS: The Monzino 80-plus is a population-based study among residents 80 years and older in the Varese province, Italy. Of 1371 eligible individuals, 1294 (94.4%), of whom 64 are centenarians, were included in the incidence study. RESULTS: Since 2002, 584 new cases of all-cause dementia were identified over 15 years. The overall incidence rate was 7.9 per 100 person-years. Dementia risk rose with age (IRR: 1.06), with the cubic model providing the best fit (R2  = 0.91-0.96). Cumulative incidences of dementia unadjusted and adjusted for competing mortality risk progressively diverged with age. CONCLUSION: Dementia incidence also keeps rising in nonagenarians and centenarians. Slowing down in growing risk of developing dementia with age is mainly attributable to increasing competing risk of death and resulting selective survival of individuals at lower risk of dementia.

Prevalence of Preventive and Symptomatic Drug Treatments in Hospice Care: An Italian Observational Study.

BACKGROUND: The aim of pharmacotherapy in people at the end of life should be symptom control, more than prolonging life. Drugs for disease prevention should therefore be discouraged, but this is not the usual practice. The prevalence of unnecessary preventive drugs at the end of life is not well described, although some studies suggest it is common. METHODS: This retrospective longitudinal study describes the prevalence of patients receiving preventive and symptomatic drug treatments at admission (T1) and before death (T2) in an Italian hospice. All adults admitted to the VIDAS hospice between March 2015 and February 2017 were included in the analysis. RESULTS: The study sample comprised 589 end-of-life patients with a mean age of 75.3 (12.1) years. The mean number of drugs decreased from admission to the hospice to the time of death (mean [standard deviation]: 9.7 [3.4] and 8.7 [3.0]). All patients were appropriately treated with symptomatic drugs at T1 and T2, while there were significantly fewer patients from T1 to T2 with at least 1 preventive medication that could be considered for deprescription at the end of life (511, 86.8% and 286, 48.6%; P < .0001). CONCLUSIONS: Hospice admission can be associated with a definite reduction in the use of commonly prescribed preventive medications. However, about half of end-of-life patients can be prescribed avoidable medications. Drugs for peptic ulcer and gastroesophageal reflux disease and antithrombotics were the potentially avoidable preventive medications most frequently prescribed at admission to the hospice and before death.

Relationship between atrial fibrillation and cognitive decline in individuals aged 80 and older.

BACKGROUND: Atrial fibrillation (AF) and dementia are largely prevalent and incident in progressively older subjects, suggesting a link between the two conditions. While in the general population there are several findings supporting a causal relationship between AF and dementia, it is unclear whether or not this association is still present in individuals aged 80 and older. RESULTS: So far, the few studies that analysed this issue did not provide enough evidence supporting the causative role of AF in increasing the risk of cognitive decline or dementia in patients aged 80 and older. Conversely, a relevant role of optimal anticoagulation control in determining a significant reduction in the risk of cognitive decline is suggested, in AF subjects aged 80years or older. CONCLUSIONS: Further data, coming from population-based studies specifically investigating very old individuals and based upon large samples and comprehensive cognitive assessments, are needed to fully elucidate the relationship between AF and dementia in very old individuals.

Prevalence of dementia in the oldest old: the Monzino 80-plus population based study.

BACKGROUND: Epidemiological studies commonly include too few of the oldest old to provide accurate prevalence rates of dementia in older age groups. Estimates of the number of those affected, necessary for healthcare planning, are thus flawed. The objective is to estimate the prevalence of dementia and levels of dementia severity in a very large population of oldest old and to investigate the relation between age and dementia prevalence in the extreme ages. METHODS: The Monzino 80-plus is a population-based study among residents 80 years or older in Varese province, Italy. Dementia cases were identified using a one-phase design. The survey was conducted in the participant's place of residence, whether home or institution. Both participants and informants were interviewed. Information was available for 2504 of the 2813 residents (89%). RESULTS: In all, 894 individuals (714 women and 180 men) met the Diagnostic and Statistical Manual of Mental Disorders (fourth edition) criteria for dementia, for a standardized prevalence of 25.3% (95% confidence interval [CI]: 23.4, 27.2%), 28.5% (95% CI: 26.2, 30.9) in women and 18.6% (95% CI: 15.2, 21.9) in men. Age-specific prevalence estimates of dementia increased with age from 15.7% at age 80 to 84 years to 65.9% at age 100 years and higher. For women, prevalence continued to rise after age 100 years, from 64.8% at age 100 to 101 years to 76.1% at age 102 to 107 years. After age 85 years prevalence rates tended to rise linearly, on average 2.6% per year in women and 1.8% in men. About 80% of the cases were moderate or severe. The frequency of mild dementia decreased and that of severe dementia increased with age. CONCLUSION: One-quarter of 80-plus year olds are affected by dementia, mostly moderate or severe. Prevalence rates of dementia do not level off, but continue to rise gradually even in the extreme ages.

Postural stability and history of falls in cognitively able older adults: the Canton Ticino study.

Falls are common events in the elderly and represent the main risk factor for fractures and other injuries. Strategies for fall prevention rely on the multifactorial assessment of the risk of falling. The contribution of instrumented balance assessment to the prediction of falls remains unclear in the literature. In this study, we analyzed the association between the fall-history of a wide sample of older people without dementia and the values of a set of posturographic parameters acquired in different visual, proprioceptive and mental conditions. A consecutive sample of 130 cognitively able elderly subjects, age≥70 years, was analyzed. Based on their fall-history in the last year, subjects were categorized into non-fallers (NF), fallers (F) and recurrent fallers (RF>2 falls). Each subject was assessed by measurements of cognition and functional ability. Static posturography tests were performed in five conditions: with eyes open/close (EO/EC) on a firm/compliant (FS/CS) surface and while performing a cognitive task. The center of pressure (COP) mean position referred to the mid-point of the heels, area of the 95% confidence ellipse, sway mean velocities and RMS displacements in the antero-posterior (AP) and medio-lateral (ML) directions were computed and their association with the fall-history was assessed. The mean position of the COP in the AP direction and the confidence ellipse area were associated with the fall-history in the EOFS, ECFS and EOCS conditions (P<0.05). RMS displacements were also associated with the fall-history in the EOCS condition (P<0.05). Significant group differences (P<0.05) were found in the EOCS conditions, which greatly enhanced the differences among NF, F and RF. The ability to control balance while standing with eyes open on a compliant surface showed a high degree of association with the fall-history of older people with no or mild cognitive impairment.

A Population-based study of dementia in the oldest old: the Monzino 80-plus study.

BACKGROUND: Despite being the fastest growing and the most cognitively impaired age group, the oldest olds are under-represented in clinical research. The purpose of this study was to describe the design, methods, and baseline characteristics of the survey population and investigate possible differences in demographic, cognitive, functional, and behavioral characteristics between oldest old with and without any performance on cognitive tests and between oldest old alive and those deceased prior to the interview. METHODS: The Monzino 80-plus Study is a prospective door-to-door population-based survey among 80 years or older residents in the municipalities in the province of Varese, Italy. Dementia cases were identified with a one-phase design. Trained psychologists interviewed both the subject and a proxy informant. The interview included a comprehensive standardized questionnaire together with an array of rating scales and a multidomain cognitive battery to assess cognitive and functional ability, behavioral disturbances and mood. RESULTS: Information was available for 2,139 of the 2,428 registered individuals aged 80 years or older. Main baseline characteristics of the population are reported and discussed. In comparison with those living, elderly persons who had died before the first visit were older, had twice the rate of institutionalization, poorer cognitive performance and competence, and significantly greater instrumental and basic functional disability. The percentage of elderly persons, alive at baseline, without Mini-Mental State Examination rose rather evenly with age. Moreover, they had significantly worse cognitive competence and functional ability, and reported higher prevalences of depressive symptoms and problem behaviors than those with Mini-Mental State Examination. CONCLUSIONS: Prospective investigation of a large population of oldest old can contribute significantly to understanding the relations between age, cognitive decline, and dementia occurrence. Use of informant-based instruments in surveys in the oldest old is crucial in assessing everyday functioning and changes, especially in participants with no cognitive test performance available. Failure to include information on deceased elderly would underestimate, increasingly with age, the prevalence of cognitive and functional disability in the elderly population.

Prevalence, incidence and types of mild anemia in the elderly: the "Health and Anemia" population-based study.

BACKGROUND: Hemoglobin concentrations slightly below the lower limit of normal are a common laboratory finding in the elderly, but scant evidence is available on the actual occurrence of mild anemia despite its potential effect on health. The objectives of this study were to estimate the prevalence and incidence of mild grade anemia and to assess the frequency of anemia types in the elderly. DESIGN AND METHODS: This was a prospective, population-based study in all residents 65 years or older in Biella, Italy. RESULTS: Blood test results were available for analysis from 8,744 elderly. Hemoglobin concentration decreased and mild anemia increased steadily with increasing age. Mild anemia (defined as a hemoglobin concentration of 10.0-11.9 g/dL in women and 10.0-12.9 g/dL in men) affected 11.8% of the elderly included in the analysis, while the estimated prevalence in the entire population was 11.1%. Before hemoglobin determination, most mildly anemic individuals perceived themselves as non-anemic. Chronic disease anemia, thalassemia trait, and renal insufficiency were the most frequent types of mild anemia. The underlying cause of mild anemia remained unexplained in 26.4% of the cases, almost one third of which might be accounted for by myelodysplastic syndromes. In a random sample of non-anemic elderly at baseline (n=529), after about 2 years, the annual incidence rate of mild anemia was 22.5 per 1000 person-years and increased with increasing age. CONCLUSIONS: The prevalence and incidence of mild anemia increase with age and mild anemia affects more than one out of ten elderly individuals. Unexplained anemia is common and may be due to myelodysplastic syndromes in some cases.
