Active clinical trials for "Delirium"

This will be the first large cohort study to define the epidemiology of and identify modifiable risk factors for long-term CI and functional deficits of ICU survivors. The investigators will measure the independent contribution of risk factors such as delirium and exposure to sedative and analgesic medications to the incidence of long-term CI, controlling for established risk factors (e.g., age, pre-existing CI, and apoE genotype). Defining the contributions of these risk factors will make it possible to develop preventive and/or treatment strategies to reduce the incidence, severity and/or duration of long-term CI and improve functional recovery of patients with acute critical illness.

The study intends to measure the evolution over time of the cognitive capacity of patients undergoing cataract surgery in relation to the opaque lens removal surgery (cataract) in a population considered to be at risk of neurocognitive degeneration. Secondary objectives: • Estimate the incidence of postoperative cognitive dysfunctions and any episodes of perioperative delirium with the aim of demonstrating the safety of cataract surgery in the elderly patient in terms of cognitive functions and impact on the psychological state. In the context of the study a risk sub-population analysis will be carried out, evaluating the trend over time of the "endothelial cells count" parameter The elderly population remains, due to the aging of the cornea, a population "at risk" for significant alterations from the clinical point of view. During the study the endothelial cells count will be monitored, in order to be able to evaluate the safety of the cataract surgery and to be able to correctly correlate a possible deterioration in the visual acuity of patients with corneal decompensation. To evaluate the progress of the endothelial cells count in the elderly patient during the pre-intervention and post-intervention period. Since the low values of cellular media in endothelial microscopy are an element that increases the risk of complications during cataract surgery, the study wants to assess how waiting times between filter visits and cataract surgery can cause an elderly patient worsening of this parameter even in a few months. The trend of the same parameter will be monitored even after the intervention since in case of decrease, the low endothelial count could cause an alteration of visual acuity and therefore a minor improvement in cognitive performance. The research will be set as a longitudinal observational study where will be compared in each patient the parameters analyzed in the 6 months prior to cataract surgery and in the 3 months following the operation itself. Patients will be enrolled during the first cataract filter visit, will be submitted to simple questions and their clinical data will be collected. Subsequently, before and after three months of surgery repeated cognitive testing and the control normally performed instrumental tests during follow-up. A clinical follow-up will be provided, during normal follow-up visits at 20 days and 6 months after the patient's surgery: the following information will be collected during these visits BCVA (visual acuity) endothelial cells microscopy OCT macula and optic nerve Catquest 9SF; Barthel Index; Six Item Cognitive Test Confusion Assessment Method (CAM): this exam will be performed within 24 hours of post-surgery and 20 days after surgery. It is important to underline that the cognitive tests proposed to patients consist of simple questions that do not depend on the visual ability of the subject.

The investigators aim to conduct a qualitative study evaluating the long and short-term recollection and experiences of critically ill children with delirium as well as collect the lived experience of the caregiver and healthcare provider involved in the patient's care. The investigators objective is to determine if there are common themes to these experiences, and if these themes are associated with specific pediatric delirium subtypes (hypoactive, hyperactive, and mixed). The overall goal is to better understand the impact of delirium on patients and their caregivers, and develop strategies to improve education, prevention and management when caring for children with pediatric intensive care unit(PICU)-acquired delirium.

The purpose of this study is to identify the association between analgesic management with blockade of the iliac fascia versus intravenous analgesia with the presence of delirium during hospital stay in patients admitted to the orthogeriatric clinical care center, to determine the opioid consumption of both groups of patients during hospitalization and determine the risk factors that may be associated with a greater presentation of delirium.

Our purpose of this study is to determine whether bright light therapy is effective for reducing the incidence and the duration of delirium compared to the usual treatment in patients at the Intensive Care Unit. Our hypothesis is that bright light therapy is effective for reducing the incidence and duration of delirium in patients at the Intensive Care Unit Patients will be assigned to a chamber with or without bright light therapy. This assignment is based on occupation of ICU beds and availability of nurses and is therefore independent from patients characteristics. Patients will be included following the inclusion criterion and exclusion criteria. Patients assigned to a chamber with bright light therapy will receive light therapy for three hours in the morning, from eight o'clock till eleven o'clock. The Confusion Assessment Method-score (CAM-score) and the Richmond Agitation Sedation Scale-score (RASS-score) will be performed three times at one day by ICU nurses, this is according to the existing routine. Besides this, an extra CAM-score and a clinical assessment will be performed once a day by a trained non-clinician, to determine the presence of delirium. The use of sedatives, haldol and fixation will be registered to determine the occurrence, duration and severity of delirium. Eventually the most important outcomes will be the clinical assessment of the patients, the CAM-score and the use of haldol. The primary outcome of this study is the duration of delirium, defined in number of days.

Patients are part of a family network. When any person in a family becomes critically unwell and requires the assistance of an Intensive Care Unit (ICU), this has an impact on all members of that family. COVID-19 changed visiting for all patients in hospitals across Scotland. It is not known what effect these restrictions will have on patients' recovery, nor do we understand the impact it may have on their relatives or staff caring for them. This study will look at the implications of the visiting restrictions as a consequence of the COVID-19 pandemic upon patients without COVID-19 who are in the cardiothoracic ICU. It will also explore the impact of these restrictions on them, their relatives and staff. This study will be carried out within a single specialised intensive care unit in Scotland using mixed methods. The first arm of this study will use retrospective data that is routinely collected in normal clinical practice. The investigators will compare patient outcomes prior to COVID-19 with outcomes following the implementation of COVID-19 visiting restrictions. The aim is to establish if the restrictions on visiting has an impact on the duration of delirium. Delirium is an acute mental confusion and is associated with longer hospital stays and worse outcomes in this patient group. The second arm of this study involves semi-structured interviews with patients, relatives and staff that will allow deeper exploration of the issues around current visiting policy. The interviews will last approximately 1 hour and will address these issues. They will then be transcribed word for word and analysed using grounded theory, meaning the theories will develop from the data as it is analysed.

This project is a multicenter pilot project to evaluate the therapeutic success in the long term up to 3 months after a delirium in a recovery room. There is a Europe-wide recommendation for the prevention of postoperative delirium in older patients and the evidence and consensus-based guideline "Management of delirium, analgesia and sedation in intensiv care medicine" of the AWMF (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften) are regularly updated for the detection and treatment of delirium in the intensive care unit. The aim is to evaluate the effects of a systematic delirium screening and the delirium treatment options in the long term in the same way as the current recommendations for the patient cohort of the recovery room.

The purpose of this study is to explore characteristic changes of EEG epileptiform discharges in patients under CPB and correlation with POD

The purpose of this study is to evaluate associations between neuronal damage biomarkers (S100 calcium-binding protein beta [S-100β], neuron-specific enolase [NSE], ubiquitin carboxy-terminal hydrolase L1 [UCHL1], and brain-derived neurotropic factor [BDNF]) and delirium severity and subsyndromal delirium in a homogeneous population of mechanically ventilated patients with sepsis.

'Post perfusion syndrome' was a term historically associated to cardiac surgery in view of the transient neuro-cognitive deficits attributed to cardio pulmonary bypass pump. During their recovery period, a significant number of patients experience delirium, a clinical syndrome of acute onset and fluctuant course.Though these deficits are often known to be transient without any permanent physical or neurological impairment, the experience can still psycho-socially affect these patients for a longer length of time even after discharge. The presence of delirium puts excessive, undesired strain on the patient, their families, health care providers and hospital resources. PTSS is an anxiety disorder caused by very stressful, frightening or distressing events. It is known to either develop immediately after the disturbing event or weeks and months later. The actual symptoms can be varied but are categorized in three sections: i.e.: re-experiencing, avoidance and emotional numbing and hyperarousal (feeling 'on edge'). A problem that has such an impact on any patient is worth investigating and understood better. Being in such a unique professional position, as a Clinical nurse practitioner, the investigator is ideally placed to conduct this study. In this study, the researcher will be focusing on the pre-operative risk factors in developing delirium, actual incidence of delirium and follow the patients post operatively to evaluate the after effects of delirium in the form of PTSS.
