Show moreThe ageing of the world’s population requires new methods to prevent adverse outcomes such as delirium in older patients after surgery. Delirium is an expression of depleted reserves, which in turn decreases a patient’s resilience and makes a patient more frail. It may be triggered due to precipitating risk factors that shift the balance and overflow a patient’s resilience. A systematic review and meta-analysis demonstrated that delirium can be prevented by implementing multicomponent interventions. Therefore, a new multicomponent prehabilitation intervention was designed. The incidence of delirium was successfully reduced by implementing this prehabilitation program, however no effects were seen on all other short-term outcomes. On the long term, postoperative delirium increases the risk of 1-year mortality over 4 times and is associated with decreased functional outcomes after 6 and 12 months. Moreover, surgery and subsequent delirium affect the quality of life of patients and caregivers and may lead to depressive symptoms. Faster return to preoperative functioning may therefore be key to a faster return to preoperative quality of life. Future perioperative care pathways focusing on delirium prevention, optimisation and fast return to baseline functioning after surgery, should begin prior to hospital admission and end long after discharge.

Show moreThe thyroid gland plays a crucial role in regulating nearly all bodily processes. A particular state of thyroid function, dubbed subclinical hypothyroidism (with high thyroid-stimulating hormone [TSH] and normal free thyroid hormone [fT4] in blood tests), becomes more prevalent with advancing age and it is unclear how this condition should be interpreted in community-dwelling older people (arbitrarily 65 years and older). Whether or not the condition is associated with negative health consequences, and whether treatment with levothyroxine (artificial thyroid hormone) is warranted, are subjects of decades-long debate. This thesis aims to identify whether subclinical hypothyroidism is associated with a range of relevant outcomes, and whether levothyroxine treatment leads to benefits, in community-dwelling older persons. The results in this thesis demonstrate that subclinical hypothyroidism is not associated with clinically (e.g. physical and cognitive function, mood or mortality risk) or biologically (e.g. thyroid antibodies or anaemia) relevant outcomes. Levothyroxine treatment does not provide benefits. These results suggest that subclinical hypothyroidism in older people is a strictly biochemical diagnosis, they support more conservative diagnostic approaches and do not support routine treatment with levothyroxine. More research is needed before extrapolating to more specific subgroups and to assess whether international guidelines should be updated. Show less

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
