Show moreIn this thesis, the effectiveness and feasibility of two proactive care programs, implemented in the emergency department (ED) of Haaglanden Medical Center in The Hague are evaluated. The first part of the thesis focuses on a screening and intervention program for hazardous alcohol use in adult ED patients. Although in the subset of patients reached for follow-up, receiving an intervention was associated with reduced alcohol consumption after three months, many patients were not screened and less than half of eligible patients received an intervention. Moreover, risk factors for hazardous alcohol use were more common in unscreened than in screened patients. In the second part of the thesis, the effect of telephone follow-up after ED discharge for community-dwelling older patients on health-related outcomes, including unplanned hospital admissions and ED return visits within 30 days, is examined. As the intervention turned out not to be effective, we investigated reasons for unplanned ED return visits in older adults to assess whether post-ED discharge interventions are sufficiently attuned to the reasons for unplanned ED return.In conclusion, none of the interventions were effective. Moreover, feasibility of the programs was limited, as many eligible patients were not reached, due to both staff-related and patient-related reasons. Show less

Show moreDue to a shorter remaining life expectancy, the risk of recurrence in older patients with low risk breast cancer is often reduced and the benefit of treatments may be very limited, especially with adjuvant treatments. In the first part of this thesis, we studied the interplay between breast cancer mortality and other-cause mortality. In the second part of this thesis, we investigated the effect of surgery and radiotherapy in subsets of the older population of patients with breast cancer in which the actual treatment effect is questionable.

Show moreAs the population is aging worldwide, and in spite of all preventive efforts, age-related diseases are increasingly prevalent, such as cardiovascular diseases and cognitive impairment. Different vascular risk factors, both the ‘traditional’ modifiable factors, such as hypertension or diabetes, and non-modifiable factors, such as age or gender, can lead to different kind of intertwined micro- and macrovascular diseases in various or multiple simultaneous organs. There is a growing need for knowledge regarding the interplay between different (co)morbidities, the relation of (co)morbidities with the various underlying pathophysiological mechanisms and treatment options of these (co)morbidities. Therefore, the aims of this thesis were to identify patients at high cardiovascular risk and to optimize treatment for these patients. We further unravelled the complexity of various interacting (poly) vascular diseases, ultimately leading to an increased risk of not only cognitive impairment, but also MACE including death. Identification of these patients and better understanding of the interplay and underlying mechanisms of these diseases is the first step towards preventive strategies. Treating these high risk patients can be a therapeutic challenge, but there is growing knowledge regarding both established and evolving therapies to optimize efficacy and efficiency. Show less

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

Show moreThe number of older people in the population is rising and so is the number of older patients in the Emergency Department (ED). Older patients often have complex problems which leads to an increased change of repeat ED visits, longer length of stay, higher chance of hospital admission and higher chance of negative health outcomes. Cognitive impairment is a frequent problem in older ED patients but often remains unrecognized and little is known about the association between cognitive impairment and adverse outcomes in older ED patients. In this thesis we show that cognitive impairment is associated with adverse outcomes in acutely presenting older patients. Secondly, we show that routinely collected parameters in addition to cognitive impairment can be used to screen for high risk of adverse outcomes in older ED patients. We investigated two delirium screeners and showed the CAM-ICU might not be suitable for early detection of delirium in the ED. Finally, vital signs that associate with decreased brain perfusion and oxygenation, such as low systolic blood pressure, were associated with cognitive impairment in older ED patients. Next steps would be to investigate if optimal resuscitation might improve cognition and decrease risk of subsequent delirium and adverse outcomes. 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
