Show moreThe growing number of older patients presenting to Emergency Departments (EDs) requires better risk stratification to guide treatment and dispositiondecisions. Therefore, it is essential to understand the effect of age on the associations between physiological variables and outcomes. More importantly, most risk tools are not age or sex adjusted and are not based on a statistical approach. An age and sex adjusted risk tool could improve risk stratification in the ED.This thesis is divided into three parts and has four aims, regarding ageadjusted interpretation of physiological variables for risk stratification in ED patients, developing a new age- and sex-adjusted risk tool for the hospital, and describing potential bias if risk tools are used for comparing the quality of care among departments.

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 moreOrthostatic hypotension (OH) is an established and common cardiovascular risk factor for falls. An in-depth understanding of the various interacting pathophysiological pathways contributing to OH-related falls is essential to guide improvements in diagnostic and treatment opportunities. We applied systems thinking to multidisciplinary map out causal mechanisms and risk factors. For this, we used group model building (GMB) to develop a causal loop diagram (CLD). The GMB was based on the input of experts from multiple domains related to OH and falls and all proposed mechanisms were supported by scientific literature. Our CLD is a conceptual representation of factors involved in OH-related falls, and their interrelatedness. Network analysis and feedback loops were applied to analyze and interpret the CLD, and quantitatively summarize the function and relative importance of the variables. Our CLD contains 50 variables distributed over three intrinsic domains (cerebral, cardiovascular, and musculoskeletal), and an extrinsic domain (e.g., medications). Between the variables, 181 connections and 65 feedback loops were identified. Decreased cerebral blood flow, low blood pressure, impaired baroreflex activity, and physical inactivity were identified as key factors involved in OH-related falls, based on their high centralities. Our CLD reflects the multifactorial pathophysiology of OH-related falls. It enables us to identify key elements, suggesting their potential for new diagnostic and treatment approaches in fall prevention. The interactive online CLD renders it suitable for both research and educational purposes and this CLD is the first step in the development of a computational model for simulating the effects of risk factors on falls.

Show moreDementia is a progressive, life-limiting disease. A palliative approach to care, that focuses on the quality of life of people with dementia and their relatives, is therefore indicated. Advance care planning is core to palliative care. Relatives play a major role in this, because people with dementia often become unable to indicate their preferences for future care. Palliative dementia care is still sub optimally implemented, however. Nursing home staff and relatives of people with dementia need information about dementia and palliative care to ensure it is optimally implemented. Also, ongoing communication between everyone involved in the care of a person with dementia is required, including discussions about future care needs. This facilitates a palliative care approach in dementia. These conclusions result from a survey among elderly care physicians, a systematic review, care plan data in nursing homes and an intervention study in two nursing homes: the mySupport study. It appears that relatives want timely information about the end of life with dementia. That way they can prepare. Although physicians are usually the ones who educate relatives, nursing staff often have a stronger relationship with relatives. After training, they can play an important role in providing information. Show less

Show moreBackground In clinical practice and science, there is debate for which older adults the benefits of cardiovascular preventive medications (CPM) still outweigh the risks in older age. Therefore, we aimed to assess how various clinical characteristics influence the judgement of appropriateness of CPM in older adults. Method We assessed the appropriateness of CPM for adults >= 75 years with regard to clinical characteristics (cardiovascular variables, complexity of health problems, age, side effects and life expectancy) using the RAND/ University of California at Los Angeles Appropriateness Method. A multidisciplinary panel, including 11 medical professionals and 3 older representatives of the target population, received an up-to-date overview of the literature. Using 9-point Likert scales (1 = extremely inappropriate; 9 = extremely appropriate), they assessed the appropriateness of starting and stopping cholesterol lowering medication, antihypertensives and platelet aggregation inhibitors, for various theoretical clinical scenarios. There were two rating rounds, with one face-to-face discussion in between. The overall appropriateness judgments were based on the median panel ratings of the second round and level of disagreement. Results The panelists emphasized the importance of the individual context of the patient for appropriateness of CPM. They judged that in general, a history of atherosclerotic cardiovascular disease strongly adds to the appropriateness of CPM, while increasing complexity of health problems, presence of hindering or severe side effects, and life expectancy < 1 year all contribute to the inappropriateness of CPM. Age had only minor influence on the appropriateness judgments. The appropriateness judgments were different for the three types of CPM. The literature, time-to-benefit, remaining life expectancy, number needed to treat, and quality of life, were major themes in the panel discussions. The considerations to stop CPM were different from the considerations not to start CPM. Conclusion Next to the patients' individual context, which was considered decisive in the final decision to start or stop CPM, there were general trends of how clinical characteristics influenced the appropriateness, according to the multidisciplinary panel. The decision to stop, and not start CPM, appeared to be two distinct concepts. Results of this study may be used in efforts to support clinical decision making about CPM in older adults. 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 moreBackground The prevalence of impaired cognitive functioning in older patients with end stage kidney disease (ESKD) is high. We aim to describe patterns of memory, executive function or psychomotor speed and to identify nephrologic, geriatric and neuroradiologic characteristics associated with cognitive impairment in older patients approaching ESKD who have not yet started with renal replacement therapy (RRT). Methods The COPE-study (Cognitive Decline in Older Patients with ESRD) is a prospective cohort study including 157 participants aged 65 years and older approaching ESKD (eGFR <= 20 ml/min/1.73 m(2)) prior to starting with RRT. In addition to routinely collected clinical parameters related to ESKD, such as vascular disease burden and parameters of metabolic disturbance, patients received a full geriatric assessment, including extensive neuropsychological testing. In a subgroup of patients (n = 93) a brain MRI was performed. Results The median age was 75.3 years. Compared to the normative data of neuropsychological testing participants memory performance was in the 24th percentile, executive function in the 18th percentile and psychomotor speed in the 20th percentile. Independent associated characteristics of impairment in memory, executive and psychomotor speed were high age, low educational level and low functional status (all p-values < 0.003). A history of vascular disease (p = 0.007) and more white matter hyperintensities on brain MRI (p = 0.013) were associated with a lower psychomotor speed. Conclusion Older patients approaching ESKD have a high prevalence of impaired memory, executive function and psychomotor speed. The patterns of cognitive impairment and brain changes on MRI are suggestive of vascular cognitive impairment. These findings could be of potentially added value in the decision-making process concerning patients with ESKD. Show less

Show moreThe rate of adverse health outcomes 90 days after an emergency department (ED) visit is high for older patients.A comprehensive geriatric assessment (CGA) can effectively identify patients at highest risk and improve outcomes. Unfortunately, the fast-paced environment and the medical condition of the acutely ill older patient make it virtually impossible to perform a CGA in all patients in the ED. Therefore, it was the aim of the present thesis to develop a screening instrument for the ED setting to identify older patients at high risk for adverse health outcomes, in order to target them for future interventions to preserve their independency and quality of life. In a multicenter prospective cohort study a total of 2629 older ED patients were included with a mean age of 79 years old. After 90 days 805 patients (30.6%) experienced functional decline or mortality. A new screeninginstrument to identify older ED patients at risk for adverse health outcomes was developed and validated: the APOP screener. The APOP screener adequately identifies older ED patients at highest risk for functional decline or mortality and is promising for clinical use. Show less

Show moreUrinary tract infections (UTI) are among the most frequently reported infections among older persons. UTI not only causes several days of illness but may have more severe consequences, such as a decline in functioning, as well as delirium, dehydration, urosepsis, hospitalization, or even death. Annually, 20% of all older persons visit their general practitioner for a UTI and about 50% of the residents in long-term care facilities (LTCF) get a UTI. This thesis describes the possibilities for and the effects of the prevention of UTI in vulnerable very old persons. The first part of this thesis investigates the effect of infections on functioning and explores which vulnerable very old persons would benefit most from UTI prevention. The second part of this thesis describes the results of the CRANBERRY study. A double-blind randomized placebo-controlled multicentre trial in LTCF. This study investigates the effectiveness and costs of cranberry capsule use in the prevention of clinical UTI. Show less

Show moreSarcopenia in old age has been associated with a higher mortality, poor physical functioning, poor outcome of surgery and higher drug toxicity. There is no general consensus on the definition of sarcopenia. The aim of the research presented in this thesis was to assess the implications of the use of different diagnostic criteria for sarcopenia, and to define the most accurate criteria for sarcopenia. Currently used diagnostic criteria for sarcopenia can be divided into criteria based on (1) low muscle mass, (2) low muscle strength, and (3) low walking speed. This thesis describes how muscle mass can be further divided into relative muscle mass and absolute muscle mass. A higher body or fat mass is associated with a lower relative muscle mass and with a higher absolute muscle mass. Higher relative muscle mass at old age is associated with better physical performance and with less insulin resistance. It is suggested to reserve the term sarcopenia to describe a low muscle mass and dynapenia to describe a low muscle strength. Most importantly, this research illustrates that it is impossible to compare studies about sarcopenia in scientific literature due to the use of different diagnostic criteria for sarcopenia.
