Show moreCholesterol-lowering medications aim to prevent cardiovascular events, caused by arteriosclerosis. Older adults (75 years and older) have a high cardiovascular risk based on age alone, and it is estimated that 1 in 3 older adults use cholesterol-lowering medication. The vast majority (96% in the Netherlands) use a statin.The appropriateness of cholesterol-lowering medication for older adults is under debate. While there is strong evidence for the benefits of statins in relatively healthy older adults with a history of cardiovascular disease, for other groups the evidence is less convincing. Also, statins are associated with hindering side effects. In this thesis, various aspects of the appropriateness of cholesterol-lowering medication for older adults were studied, using different research designs. Five recurrent themes were of the utmost importance in the assessment of the appropriateness of cholesterol-lowering medication in older adults; 1) the individual context of a patient, 2) life expectancy, 3) hindering side effects, 4) cardiovascular history, and 5) the complexity of health problems. Based in these five themes, five key questions were distilled that can be used in a systematic evaluation of the appropriateness of cholesterol- lowering treatment for an individual patient.

Show morePurposePre-stroke frailty in older adults is associated with adverse outcomes after stroke in community-based and hospital-based populations. The aim of our study was to investigate the prevalence of pre-stroke frailty among older stroke survivors receiving medical specialistic rehabilitation and its association with outcomes and recovery.MethodsPre-stroke frailty was measured by the Groningen Frailty Indicator (GFI, score ≥ 4 indicates frailty) in patients ≥ 65 years receiving stroke medical specialistic rehabilitation. Baseline, follow-up and change (i.e. recovery) scores of the Barthel index (BI), Stroke Impact Scale (SIS) ‘mobility’, ‘communication’, and ‘memory and thinking’, Hospital Anxiety and Depression Scale (HADS) and the EuroQoL-5 dimensions (EQ-5D) were compared between frail and non-frail patients with a multivariable regression model adjusting for confounders.ResultsOf 322 included patients (34.2% females, median age 70 years), 43 (13.4%) patients reported pre-stroke frailty. There were no differences in BI or in destination of discharge between pre-stroke frail and non-frail stroke survivors receiving inpatient rehabilitation. However, pre-stroke frailty was associated with worse follow-up scores for all other measures. Recovery in pre-stroke frail patients was less favorable compared to non-frail patients for SIS mobility, HADS subscales and EQ-5D index and visual analogue scale.ConclusionPre-stroke frailty was present in a minority of older stroke survivors receiving medical specialistic rehabilitation. BI and destination of discharge did not differ. Nevertheless, pre-stroke frailty was associated with worse functioning at follow-up for most measures of health status and with smaller improvements in mobility, mood and quality of life. Show less

Show moreBackgroundIn the general population, an increase in low-density lipoprotein cholesterol (LDL-C) predicts higher cardiovascular disease risk, and lowering LDL-C can prevent cardiovascular disease and reduces mortality risk. Interestingly, in cohort studies that include very old populations, no or inverse associations between LDL-C and mortality have been observed. This study aims to investigate whether the association between LDL-C and mortality in the very old is modified by a composite fitness score.MethodsA 2-stage meta-analysis of individual participant data from the 5 observational cohort studies. The composite fitness score was operationalized by performance on a combination of 4 markers: functional ability, cognitive function, grip strength, and morbidity. We pooled hazard ratios (HR) from Cox proportional-hazards models for 5-year mortality risk for a 1 mmol/L increase in LDL-C. Models were stratified by high/low composite fitness score.ResultsComposite fitness scores were calculated for 2 317 participants (median 85 years, 60% females participants), of which 994 (42.9%) had a high composite fitness score, and 694 (30.0%) had a low-composite fitness score. There was an inverse association between LDL-C and 5-year mortality risk (HR 0.87 [95% CI: 0.80–0.94]; p < .01), most pronounced in participants with a low-composite fitness score (HR 0.85 [95% CI: 0.75–0.96]; p = .01), compared to those with a high composite fitness score (HR = 0.98 [95% CI: 0.83–1.15]; p = .78), the test for subgroups differences was not significant.ConclusionsIn this very old population, there was an inverse association between LDL-C and all-cause mortality, which was most pronounced in participants with a low-composite fitness scores.

Show moreInflammatoire darmziekten (Inflammatory Bowel Disease, IBD) zijn chronische immuun-gemedieerde ziekten van het maag-darmstelsel. Het aandeel oudere patiënten met IBD, 65 jaar of ouder, wordt groter. Het behandelen van deze groep is een uitdaging, omdat zij vaak andere ziekten (comorbiditeit) hebben en geriatrische aandoeningen zoals geheugenproblemen of verminderde spiermassa. Deze aandoeningen vallen onder het begrip kwetsbaarheid, en worden gemeten met een geriatrisch assessment.Dit proefschrift richt zich op het in kaart brengen van de huidige literatuur en behandeloverwegingen bij oudere patiënten met IBD, om daarna als een van de eersten bewijs te leveren voor het invoeren van (screening naar) comorbiditeit en kwetsbaarheid bij de behandeling van oudere patiënten met IBD.Allereerst wordt onderzocht welke factoren bijdragen aan behandelbeslissingen, door behandelaren te interviewen. Leeftijd en aspecten van kwetsbaarheid beïnvloeden behandelbeslissingen, maar behandelaren verschillen onderling in hoe ze deze aspecten gebruiken. Daarnaast liet een literatuur zoektocht zien dat het bewijs over de relatie tussen kwetsbaarheid en behandeluitkomsten schaars is.Ook wordt het verband tussen comorbiditeit en veiligheid van biologicals, medicijnen die ontstekingseiwitten of afweercellen remmen, onderzocht. De aanwezigheid van meer comorbiditeit geeft een hoger risico op bijwerkingen (infecties en ziekenhuisopnames), een hogere leeftijd geeft dat niet.Tenslotte wordt de prevalentie van kwetsbaarheid in een Nederlands cohort van oudere patiënten met IBD onderzocht. Bij ongeveer de helft was er kwetsbaarheid. Hoe kwetsbaarder, hoe hoger de IBD-ziekteactiviteit en de IBD-ziektelast. Kwetsbare patiënten hadden, onafhankelijk van hun leeftijd en IBD-ziekteactiviteit, een hogere kans op ziekenhuisopnames en infecties, maar ook op achteruitgang in zelfstandigheid en kwaliteit van leven.

Show moreBackground: There is a lack of information on mental health outcomes for the increasing older population. Therefore, the aim of the current study is to assess depressive symptoms, loneliness, and apathy in older patients with breast cancer within the first 5 years after diagnosis.Methods: Women aged >= 70 years with early-stage breast cancer were included. Multivariate linear mixed models were used to assess longitudinal changes in symptoms of depression (according to the 15-item Geriatric Depression Scale), loneliness (according to the De Jong Gierveld Loneliness Scale) and apathy (according to the Starkstein Apathy Scale) over time at 3, 9, 15, 27 and 60 months follow-up.Results: In total, 299 patients were included (mean [standard deviation (SD)] age: 75.8 [5.2] years). At 3 months follow-up, shortly after the acute treatment, 10% of patients had sig-nificant depressive symptoms, while loneliness and apathy were present in 31% and 41% of all patients, respectively. Depression, loneliness and apathy scores showed no clinically relevant changes over time in the whole cohort. Patients who received adjuvant systemic therapies (i.e. endocrine therapy and/or chemotherapy and/or targeted therapy (trastuzumab)) had si-milar mental health outcomes as those who did not. However, frail patients had more symptoms (p < 0.001) and were more prone to develop depressive symptoms over time than non-frail patients (p = 0.002).Discussion: Depression, loneliness and apathy were frequently observed in older women with breast cancer and did not change over time. Patients who received adjuvant systemic therapies had similar mental health outcomes as those who did not. However, frail patients were at higher risk to experience these symptoms.(c) 2023 The Author(s). Published by Elsevier Ltd.

Show morePurposeOlder patients with COVID-19 can present with atypical complaints, such as falls or delirium. In other diseases, such an atypical presentation is associated with worse clinical outcomes. However, it is not known whether this extends to COVID-19. We aimed to study the association between atypical presentation of COVID-19, frailty and adverse outcomes, as well as the incidence of atypical presentation.MethodsWe conducted a retrospective observational multi-center cohort study in eight hospitals in the Netherlands. We included patients aged >= 70 years hospitalized with COVID-19 between February 2020 until May 2020. Atypical presentation of COVID-19 was defined as presentation without fever, cough and/or dyspnea. We collected data concerning symptoms on admission, demographics and frailty parameters [e.g., Charlson Comorbidity Index (CCI) and Clinical Frailty Scale (CFS)]. Outcome data included Intensive Care Unit (ICU) admission, discharge destination and 30-day mortality.ResultsWe included 780 patients, 9.5% (n = 74) of those patients had an atypical presentation. Patients with an atypical presentation were older (80 years, IQR 76-86 years; versus 79 years, IQR 74-84, p = 0.044) and were more often classified as severely frail (CFS 6-9) compared to patients with a typical presentation (47.6% vs 28.7%, p = 0.004). Overall, there was no significant difference in 30-day mortality between the two groups in univariate analysis (32.4% vs 41.5%; p = 0.173) or in multivariate analysis [OR 0.59 (95% CI 0.34-1.0); p = 0.058].ConclusionsIn this study, patients with an atypical presentation of COVID-19 were more frail compared to patients with a typical presentation. Contrary to our expectations, an atypical presentation was not associated with worse outcomes.Key Summary PointsAimTo study the association between atypical presentation of COVID-19, frailty and adverse outcomes, as well as the incidence of atypical presentation.FindingsIn this study, an atypical presentation of COVID-19 was significantly associated with frailty. However, patients with an atypical presentation of COVID-19 did not have worse disease outcomes.MessagePhysicians need to remain alert for COVID-19 in frail older patients, as they may present without typical complaints.

Show moreIntroduction: Vulvar cancer is a disease that mainly affects older women. Frailty is an important predictor of outcomes and geriatric assessment can help tailor treatment decisions and improve outcomes. This study aims to assess the prevalence of frailty in older women with vulvar cancer, and how it relates to integrated geriatric care and treatment according to the oncological guidelines. Materials and Methods: A single-center cohort study was performed, among patients 70 years and older, who were diagnosed with vulvar cancer at Leiden University Medical Center, between January 2012 and May 2020. Data on geriatric assessment, treatment decision-making and treatment-related outcomes were collected. Results: Our study included 114 patients. Mean age was 79.7 years, and 52 patients (45.6%) were frail. Of the frail patients, 42.0% were referred to a geriatrician. In eight of these cases, the geriatrician was actively involved in weighing the benefit and harm of standard oncological treatment versus de-escalated treatment. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with referral to a geriatrician and with active involvement of a geriatrician in decision making. In 26 of frail patients (50.0%) oncological treatment was de-escalated. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with de-escalation of treatment. De-escalated treatment did not compromise survival. Discussion: Frailty is prevalent among older women with vulvar cancer and is associated with referral to a geriatrician and de-escalation of oncological treatment. While this reflects that it is deemed important to tailor treatment decision for frail patients, most frail patients are not routinely evaluated by a geriatrician. Further multidisciplinary collaboration and research is necessary to optimize tailored treatment decisions for this patient group. Show less

Show moreIn studies of recurrent events, joint modeling approaches are often needed to allow for potential dependent censoring by a terminal event such as death. Joint frailty models for recurrent events and death with an additional dependence parameter have been studied for cases in which individuals are observed from the start of the event processes. However, samples are often selected at a later time, which results in delayed entry so that only individuals who have not yet experienced the terminal event will be included. In joint frailty models such left truncation has effects on the frailty distribution that need to be accounted for in both the recurrence process and the terminal event process, if the two are associated. We demonstrate, in a comprehensive simulation study, the effects that not adjusting for late entry can have and derive the correctly adjusted marginal likelihood, which can be expressed as a ratio of two integrals over the frailty distribution. We extend the estimation method of Liu and Huang (Stat Med 27:2665-2683, 2008.) to include potential left truncation. Numerical integration is performed by Gaussian quadrature, the baseline intensities are specified as piecewise constant functions, potential covariates are assumed to have multiplicative effects on the intensities. We apply the method to estimate age-specific intensities of recurrent urinary tract infections and mortality in an older population. Show less

Show morePurpose: Chronic subdural hematoma (CSDH) is a common neurological disease often affecting the elderly. Long-term excess mortality for patients after CSDH has been suggested but causes of death are unknown. We hypothesize that excess mortality of CSDH patients is related to frailty. In this article, we describe mortality rates and causes of death of CSDH patients compared with the general population and assess the association of frailty with mortality. Methods: A cohort study in which consecutive CSDH patients were compared to the general population regarding mortality rates. Furthermore, the association of six frailty indicators (cognitive problems, frequent falling, unable to live independently, unable to perform daily self-care, use of benzodiazepines or psychotropic drugs, and number of medications) with mortality was assessed. Results: A total of 1307 CSDH patients were included, with a mean age of 73.7 (SD +/- 11.4) years and 958 (73%) were male. Median follow-up was 56 months (range: 0-213). Compared with controls CSDH patients had a hazard ratio for mortality of 1.34 (95% CI: 1.2-1.5). CSDH patients more often died from cardiovascular diseases (37% vs. 30%) and falls (7.2% vs. 3.7%). Among CSDH patients frequent falling (HR 1.3; 95% CI: 1.0-1.7), inability to live independently (HR 1.4, 95% CI: 1.1-1.8), inability to perform daily self-care (HR 1.5; 95% CI: 1.1-1.9), and number of medications used (HR 1.0; 95% CI: 1.0-1.1) were independently associated with mortality. Conclusions: CSDH patients have higher mortality rates than the general population. Frailty in CSDH patients is associated with higher mortality risk. More attention for the frailty of CSDH patients is warranted. Show less

Show moreIntroduction: Older patients have a higher risk for complications after rectal cancer surgery. Although screening for geriatric impairments may improve risk prediction in this group, it has not been studied previously. Methods: We retrospectively investigated patients >= 70 years with elective surgery for non-metastatic rectal cancer between 2014 and 2018 in nine Dutch hospitals. The predictive value of six geriatric parameters in combination with standard preoperative predictors was studied for postoperative complications, delirium, and length of stay (LOS) using logistic regression analyses. The geriatric parameters included the four VMS -questionnaire items pertaining to functional impairment, fall risk, delirium risk, and malnutrition, as well as mobility problems and polypharmacy. Standard predictors included age, sex, body mass index, American Society of Anesthesiologists (ASA)-classification, comorbidities, tumor stage, and neoadjuvant therapy. Changes in model performance were evaluated by comparing Area Under the Curve (AUC) of the regression models with and without geriatric parameters. Results: We included 575 patients (median age 75 years; 32% female). None of the geriatric parameters improved risk prediction for complications or LOS. The addition of delirium risk to the standard preoperative prediction model improved model performance for predicting postoperative delirium (AUC 0.75 vs 0.65, p = 0.03). Conclusions: Geriatric parameters did not improve risk prediction for postoperative complications or LOS in older patients with rectal cancer. Delirium risk screening using the VMS-questionnaire improved risk prediction for delirium. Older patients undergoing rectal cancer surgery are a pre-selected group with few impairments. Geriatric screening may have additional value earlier in the care pathway before treatment decisions are made. Show less

Show moreBACKGROUND & AIMS: We aimed to perform geriatric assessment in older patients with inflammatory bowel disease (IBD) to evaluate which IBD characteristics associate with deficits in geriatric assessment and the impact of deficits on disease burden (health-related quality of life).METHODS: A prospective multicenter cohort study including 405 consecutive outpatient patients with IBD aged >= 65 years. Somatic domain (comorbidity, polypharmacy, malnutrition), impairments in (instrumental) activities of daily living, physical capacity (handgrip strength, gait speed), and mental (depressive symptoms, cognitive impairment) and social domain (life-partner) were assessed. Deficits in geriatric assessment were defined as >= 2 abnormal domains; 2-3 moderate deficits and 4-5 severe deficits. Clinical (Harvey Bradshaw Index >4/partial Mayo Score >2) and biochemical (C-reactive protein >= 10 mg/L and/or fecal calprotectin >= 250 mu g/g) disease activity and disease burden (short Inflammatory Bowel Disease Questionnaire) were assessed.RESULTS: Somatic domain (51.6%) and activities of daily living (43.0%) were most frequently impaired. A total of 160 (39.5%) patients had moderate deficits in their geriatric assessment; 32 (7.9%) severe. Clinical and biochemical disease activity associated with deficits (clinical: adjusted odds ratio, 2.191; 95% confidence interval, 1.284-3.743; P = .004; biochemical: adjusted odds ratio, 3.358; 95% confidence interval, 1.936-5.825; P <.001). Deficits in geriatric assessment independently associate with lower health-related quality of life.CONCLUSION: Deficits in geriatric assessment are highly prevalent in older patients with IBD. Patients with active disease are more prone to deficits, and deficits associate with lower health-related quality of life, indicating higher disease burden. Prospective data validating impact of frailty and geriatric assessment on outcomes are warranted to further improve treatment strategies. Show less

Show moreMulti-state models for event history analysis most commonly assume the process is Markov. This article considers tests of the Markov assumption that are applicable to general multi-state models. Two approaches using existing methodology are considered; a simple method based on including time of entry into each state as a covariate in Cox models for the transition intensities and a method involving detecting a shared frailty through a stratified Commenges-Andersen test. In addition, using the principle that under a Markov process the future rate of transitions of the process at times t > s should not be influenced by the state occupied at time s, a new class of general tests is developed by considering summaries from families of log-rank statistics where patients are grouped by the state occupied at varying initial time s. An extended form of the test applicable to models that are Markov conditional on observed covariates is also derived. The null distribution of the proposed test statistics are approximated by using wild bootstrap sampling. The approaches are compared in simulation and applied to a dataset on sleeping behavior. The most powerful test depends on the particular departure from a Markov process, although the Cox-based method maintained good power in a wide range of scenarios. The proposed class of log-rank statistic based tests are most useful in situations where the non-Markov behavior does not persist, or is not uniform in nature across patient time. Show less

Show moreThis thesis develops and investigates statistical methods for two frailty models in the analysis of time-to-event data.The first part of the thesis deals with the statistical assessment of the slowing down of human death rates at advanced ages. Such mortality deceleration can be described through the gamma-Gompertz model as an effect of selection in heterogeneous populations. As the frailty variance of this proportional hazards frailty model may lie on the boundary of the parameter space, statistical techniques have to be adjusted to this non-standard condition. Chapter 2 presents the asymptotic properties of likelihood inference in this model. In Chapter 3, aspects of study design are discussed, such as the information loss if samples are restricted to cover only survivors beyond some high age. Chapter 4 introduces focused model selection as a new approach to assessing mortality deceleration.The second part of the thesis is concerned with inference in a joint frailty model for recurrent events and a terminal event in two different observational settings. Chapter 5 considers the situation of intermittent observation of the recurrence process, such that only interval counts of recurrent events are available. Chapter 6 examines the situation of delayed entry, in which individuals can only be included in the recurrent event study if they have not yet experienced the terminal event. Show less

Findings DRAs are prevalent in older hospitalized patients. Polypharmacy, ADL dependency and a high ISAR or ISAR-HP score are associated with higher risk for a DRA, but the predictive value of geriatric screeners is insufficient and therefore they cannot be used alone to predict for Drug-Related Hospital Admissions in Emergency Department. Message Geriatric screening instruments are not specific and sensitive enough to use alone for identifying drug-related hospital admissions in older patients in the ED.Purpose Drug-Related Admissions (DRAs) are a well-known problem among older patients in the Emergency Department (ED). The aim of this study was (a) to investigate the prevalence and clinical manifestations of DRAs and the responsible drugs, (b) to study the association between geriatric characteristics and DRAs, and (c) to study the predictive performance of geriatric screeners for identifying DRAs in older ED patients. Methods Patients aged >= 70 hospitalized from the ED were included. Demographics, geriatric characteristics and medications were collected. The the Acutely Presenting Older Patient (APOP)-screener, the Identification of Seniors At Risk (ISAR) and the ISAR-Hospitalized Patients (ISAR-HP) were used as geriatric screeners. Potential DRAs were identified retrospectively, the association between geriatric screeners and DRAs was investigated with logistic regression and the predictive performance was assessed by calculating the Area under the Curve (AUC) of the Receiver Operator Characteristics (ROC). Results The mean age of patients was 78 (IQR 73-83), using an average of 6 medications. Out of 240 admissions, 77 (30%) were classified as a DRA. Independent risk factors for DRAs were polypharmacy (OR 2.42; 95% CI 1.23-4.74) and the ADL dependency (OR 1.23; 95%CI 1.05-1.44). ISAR (OR 3.27; 95%CI 1.60-6.69) and ISAR-HP (OR 1.83; 95% CI 1.02-3.27) associated with increased risk of DRAs, whereas the APOP screener did not (OR 1.56; 95% CI 0.82-2.97). The predictive performance of all geriatric screeners for predicting DRAs was poor (AUC for all screeners < 0.60). Conclusion DRAs are highly prevalent in older ED patients. Polypharmacy, ADL dependency and a high ISAR or ISAR-HP are associated with higher risk for DRAs, but the predictive value of geriatric screeners is insufficient. Show less

Show morePurpose Despite the rapidly expanding knowledge in the field of Geriatric Emergency Medicine in Europe, widespread implementation of change is still lacking. Many opportunities in everyday clinical care are missed to improve care for this susceptible and growing patient group. The aim was to develop expert clinical recommendations on Geriatric Emergency Medicine to be disseminated across Europe.Methods A group of multi-disciplinary experts in the field of Geriatric Emergency Medicine in Europe was assembled. Using a modified Delphi procedure, a prioritized list of topics related to Geriatric Emergency Medicine was created. Next, a multi-disciplinary group of nurses, geriatricians and emergency physicians performed a review of recent guidelines and literature to create recommendations. These recommendations were voted upon by a group of experts and placed on visually attractive posters. The expert group identified the following eight subject areas to develop expert recommendations on: Comprehensive Geriatric Assessment in the Emergency Department (ED), age/frailty adjusted risk stratification, delirium and cognitive impairment, medication reviews in the ED for older adults, family involvement, ED environment, silver trauma, end of life care in the acute setting.Results Eight posters with expert clinical recommendations on the most important topics in Geriatric Emergency Medicine are now available through https://posters.geriemeurope.eu/.Conclusion Expert clinical recommendations for Geriatric Emergency Medicine may help to improve care for older patients in the Emergency Department and are ready for dissemination across Europe.

Show moreIntroduction: Frail patients with colorectal cancer (CRC) are at increased risk of complications after surgery. Prehabilitation seems promising to improve this outcome and therefore we evaluated the effect of physical prehabilitation on postoperative complications in a retrospective cohort of frail CRC patients. Methods: The study consisted of all consecutive non-metastatic CRC patients >70 years who had elective surgery from 2014 to 2019 in a teaching hospital in the Netherlands, where a physical prehabilitation program was implemented from 2014 on. We performed both an intention-to-treat and per protocol analysis to evaluate postoperative complications in the physical prehabilitation (PhP) and non-prehabilitation (NP) group. Results: Eventually, 334 elective patients were included. The 124 (37.1%) patients in the PhP-group presented with higher age, higher comorbidity scores and walking-aid use compared to the NP-group. Medical complications occurred in 26.6% of the PhP-group and in 20.5% of the NP-group (p = 0.20) and surgical complications in 19.4% and 14.3% (p = 0.22) respectively. In all frailty subgroups, the medical complications were lower in the PhP-group compared to the NP-group (35.9% vs. 45.5% for patients with >2 comorbidities, 36.2% vs. 39.1% for ASA score > III, 29.2% vs. 45.8% for walking-aid use). Differences were not significant. Conclusions: In this study, patients selected for physical prehabilitation had a worse frailty profile and therefore a higher a priori risk of postoperative complications. However, the postoperative complication rate was not increased compared to patients who were less frail at baseline and without prehabilitation. Hence, physical prehabilitation may prevent postoperative complications in frail CRC patients >70 years.

Show moreOlder emergency department (ED) patients are at high risk of adverse health outcomes, such as mortality or functional decline. Early identification of those patients who are at highest risk gives an opportunity to target interventions and guide treatment decisions for those who need it most.This thesis describes the clinical value of using geriatric screening in the ED. Geriatric screening identifies older patients at high risk of both short- and long-term poor outcomes and provides valuable information for care providers treating acutely hospitalized older patients. The results from screening could aid in individualized treatment decisions to acquire more personalized care, and therefore gives an opportunity to optimize outcomes for older patients.Implementation of screening programs in the fast-paced environment of everyday ED practice remains scarce. The results of this thesis show that the implementation of a geriatric screening program in routine ED practice is feasible and the use of screening is accepted by both the users (triage nurses) and the older patients.Using geriatric screening in routine care is therefore useful and feasible. More research will be needed to investigate implementation in different hospitals to generate guidance on how geriatric screening tools can be successfully implemented on a wide scale. Show less

Elderly patients are less prone to rejection, and death censored graft loss is less frequent compared to younger recipients. Elderly recipients do have increased rates of malignancy and infection-related mortality. Poor kidney transplant function in elderly recipients may be related to both pre-existing (i.e. donor-derived) kidney damage and increased susceptibility to nephrotoxicity of calcineurin inhibitors (CNIs) in kidneys from older donors. Hence, it is pivotal to shift the focus from prevention of rejection to preservation of graft function and prevention of over-immunosuppression in the elderly. The OPTIMIZE study will test the hypothesis that reduced CNI exposure in combination with everolimus will lead to better kidney transplant function, a reduced incidence of complications and improved health-related quality of life for kidney transplant recipients aged 65 years and older, compared to standard immunosuppression.MethodsThis open label, randomized, multicenter clinical trial will include 374 elderly kidney transplant recipients (>= 65 years) and consists of two strata. Stratum A includes elderly recipients of a kidney from an elderly deceased donor and stratum B includes elderly recipients of a kidney from a living donor or from a deceased donor<65 years. In each stratum, subjects will be randomized to a standard, tacrolimus-based immunosuppressive regimen with mycophenolate mofetil and glucocorticoids or an adapted immunosuppressive regimen with reduced CNI exposure in combination with everolimus and glucocorticoids. The primary endpoint is 'successful transplantation', defined as survival with a functioning graft and an eGFR30 ml/min per 1.73 m(2) in stratum A and >= 45 ml/min per 1.73 m(2) in stratum B, after 2 years, respectively.ConclusionsThe OPTIMIZE study will help to determine the optimal immunosuppressive regimen after kidney transplantation for elderly patients and the cost-effectiveness of this regimen. It will also provide deeper insight into immunosenescence and both subjective and objective outcomes after kidney transplantation in elderly recipients.Trial registrationClinicalTrials.gov: NCT03797196, registered January 9th, 2019.

Show morePurpose Unidentified cognitive decline and other geriatric impairments are prevalent in older patients with advanced chronic kidney disease (CKD). Despite guideline recommendation of geriatric evaluation, routine geriatric assessment is not common in these patients. While high burden of vascular disease and existing pre-dialysis care pathways mandate a tailored geriatric assessment, no consensus exists on which instruments are most suitable in this population to identify geriatric impairments. Therefore, the aim of this study was to propose a geriatric assessment, based on multidisciplinary consensus, to routinely identify major geriatric impairments in older people with advanced CKD. Methods A pragmatic approach was chosen, which included focus groups, literature review, inventory of current practices, an expert consensus meeting, and pilot testing. In preparation of the consensus meeting, we composed a project team and an expert panel (n = 33), drafted selection criteria for the selection of instruments, and assessed potential instruments for the geriatric assessment. Results Selection criteria related to general geriatric domains, clinical relevance, feasibility, and duration of the assessment. The consensus-assessment contains instruments in functional, cognitive, psychological, somatic, patient preferences, nutritional status, and social domains. Administration of (seven) patient questionnaires and (ten) professional-administered instruments, by nurse (practitioners), takes estimated 20 and 40 min, respectively. Results are discussed in a multidisciplinary meeting including at least nephrology and geriatric expertise, informing nephrology treatment decisions, and follow-up interventions among which comprehensive geriatric assessment. Conclusion This first multidisciplinary consensus on nephrology-tailored geriatric assessment intent to benefit clinical care and enhance research comparability for older patients with advanced CKD.Key Summary pointsAim To propose a consensus-based geriatric assessment for optimizing both routine care and research in older patients with advanced chronic kidney disease. Findings Using a pragmatic approach, we reached consensus on a suitable nephrology-tailored geriatric assessment to routinely identify major geriatric impairments in older patients with advanced chronic kidney disease. This geriatric assessment contains instruments in functional, cognitive, psychological, somatic, patient preferences, nutritional status, and social domains, and can be administered with patient questionnaires and professional-administered instruments by nurse (practitioners) in approximately 20 and 40 minutes, respectively. Message We propose a consensus test set for standardized nephrology-tailored geriatric assessment, which is currently being implemented in multiple hospitals and studies, to benefit clinical care for older patients with advanced chronic kidney disease and enhance research comparability.
