Active clinical trials for "Delirium"

Background Delirium is an acute neuropsychiatric syndrome, and its causes remain complex and not fully comprehended. Patients in trauma intensive care units are at high risk for delirium and are greatly affected by its adverse outcomes. As there are currently no effective pharmacological treatments or approaches for delirium, it is crucial to focus on identifying the risk factors for delirium and implementing early prevention strategies. Objective Analyzing the incidence and risk factors of delirium in trauma intensive care unit patients. Method This study is a prospective research that focuses on all patients in the trauma intensive care unit of a medical center. Data collection will be conducted through questionnaires and electronic medical records. A total of 200 participants will be conveniently selected for the study. Upon admission to the intensive care unit, each patient will complete a basic information questionnaire, and their medical records will be collected daily until they are discharged from the intensive care unit. The study incorporates various assessment scales including Intensive Care Delirium Screening Checklist (ICDSC), Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), Acute Physiology and Chronic Health Evaluation II (APACHE-II), Injury Severity Score (ISS), and Malnutrition Universal Screening Tool (MUST). Statistical analysis will be done by using IBM SPSS 24.0 for Windows. Descriptive statistics including mean, standard deviation, and percentages will be used to present demographic information. Logistic regression analysis will be applied to identify the key predictive factors for delirium risk. Expected outcome and clinical application This study anticipates that the non-modifiable risk factors for trauma intensive care unit patients include age, substance use, chronic diseases, traumatic brain injury, prior surgery, frailty, APACHE II score, ISS, and ASA anesthesia classification. The modifiable risk factors include malnutrition, polypharmacy, electrolyte deficiency, metabolic acidosis, pain, mechanical ventilation, physical restraints, total surgical duration, intraoperative blood loss, and low hemoglobin. By understanding these risk factors, high-risk patients can be identified and preventive measures can be implemented to reduce the occurrence of delirium. Furthermore, addressing modifiable risk factors can help in reducing the risk or severity of delirium.

The implementation of environmental intervention program reduced the duration of delirium and length of stay at the ICU in critically-ill surgical patients.

Title: Guided Occupational Therapist (OT) Cognitive Interventions for Critically Ill Patients Short Title: GOTCI Methodology: Randomized Control Trial Study Duration: 12-15 months Study Centre: Single Center - South Health Campus, ICU, Calgary, Alberta, Canada Objectives: The aim for this study is to evaluate the effect of specific OT guided cognitive interventions on delirium in adult critically ill patients. Number of Subjects: 112 Primary Outcome: Delirium Prevalence and Duration Secondary Outcomes: Cognitive function, physical function, quality of life, ICU length of stay, hospital length of stay and days of mechanical ventilation. Inclusion Criteria: Adult Critically Ill Patients admitted to South Health Campus ICU, Calgary, Alberta Type of Intervention: OT guided cognitive intervention based on RASS score Dose: One on one therapeutic sessions with an OT. Five days a week, Monday to Friday, between 0800-1600. There will be twice daily sessions for 20 minutes each. Duration of administration: Cognitive Therapy to be initiated Monday to Friday, for the duration of participant ICU admission. Reference therapy: Standard of care within the Department of Critical Care Medicine in Calgary is delirium prevention strategies using the ABCDEF bundled approach. Statistical Methodology: Descriptive statistics (mean, median, proportion) will be employed to describe the study population. The primary outcome of delirium prevalence will be explored using multivariable logistic regression, which will provide an estimate of the odds ratio and accompanying 95% confidence intervals. Both per protocol and intent to treat analyses will be performed.

Patients with severe illness require lifesaving treatment in intensive care units. Around a third of patients admitted to intensive care develop delirium. This is a severe state of confusion. Delirium can be a frightening experience. Patients suffering from delirium can find it difficult to think clearly or understand what is happening. In some cases delirium can cause people to see or hear things that are not really there. Patients who develop delirium tend to spend longer in hospital and have worse overall outcomes. A major cause for the development of delirium is poor sleep. Previous research suggests that delirium levels can be reduced when patients are more active. The investigators have noticed that when patients in intensive care have physiotherapy during the day, they are often very tired and fall asleep quickly afterwards. The investigators think that patients who have physiotherapy in the evening will sleep better overnight and hope this will subsequently reduce the number who develop delirium. To answer this question the investigators need to compare patients who are active in the evening with those who only have physiotherapy sessions during the day. Before a full study can take place it is important to make sure it is designed in the best way. To do this, 60 patients will be recruited from 2 hospitals in the UK over 6 months. Half of those who agree to take part will be seen by the physiotherapist in the evening, the other half will not. The investigators will then ask the following questions before deciding whether to do a full study Will patients agree to be a part of this trial? Will they agree to the additional physiotherapy sessions offered in the evening? Will patients and staff members be happy for us to randomly select who receives this extra treatment?

As patient management is improving, more and more ICU survivors are being confronted with cognitive dysfunction and this well after their hospital stay. In the ICU, delirium rates have been reported to be as high at 81%. Delirium is associated with patient and family stress, increased hospital costs, increased duration of stay, escalation of care and increased mortality and morbidity. The physiopathology of ICU cognitive impairment is complex and involves an inflammatory cascade Recently, the role of 'resolvins' derived from omega-3 fatty acids has been studied in the resolution of inflammation. Therefore, this hypothesis of this study is that ICU patients with higher serum levels of resolvins at ICU admission, ICU day 2 and day 5 will have a lesser degree of cognitive impairment on day 5 of ICU stay.

In population of intensive care unit (ICU), most studies compared atypical antipsychotics such as quetiapine with the traditional haloperidol in delirious patients of various forms and etiologies. The role of such agents in patients with hyperactive is not fully understood. This study compares the effectiveness of quetiapine with haloperidol in treating the hyperactive form of delirium in terms of their effects on morbidity, length of stay in the intensive care unit, and mortality in critically ill patients.

In the last two decades, viral infections have increased dramatically : the 2003 severe acute respiratory syndrome coronavirus outbreak, the 2009 swine flu pandemic, the 2012 Middle East respiratory syndrome coronavirus outbreak, the 2013-2016 Ebola virus disease epidemic in West Africa and the 2015 Zika virus disease epidemic and not least the COVID-19 pandemic. At the same time, neurological disorders are a major and increasing global health challenge, which accounts for a substantial portion of the disease burden worldwide . In Europe, more than half of the population (approx. 60% ) suffers from a neurological disease, ranking number three among all disease groups . The figures are higher in the population with more than 65 years. Based on Eurostat annual publication "Aging Europe", in 2020 people over 65 represented 20.6% of the European Union population, and the projections show that the share of people over 65 is expected to strongly increase until 2058, reaching 30.3% of the EU population. Furthermore, while in civil aviation, the mortality rate is estimated around 0,00525% (Eurocontrol, 2022), the perioperative mortality rate in Europe is about 4% (Pearse et al., 2012). Clearly, the patients undergoing surgery already have a higher mortality risk depending on their initial medical conditions. However, the medical field can without doubts benefit from an improved risks assessment approach derived from the civil aviation. Against this backdrop, the project aims at: i) researching the correlation between a neurotoxic viruses' infection and the increased risk, in terms of frequency or severity, of developing a cognitive disfunction such as the postoperative cognitive dysfunction (POCD), by conducting an observational clinical trial on selected neurotoxic viruses (SARS-CoV-2, Herpes simplex virus, Cytomegalovirus and Epstein Barr virus). ii) developing a theoretical model for monitoring the implications of general anaesthesia in elder patients aged ≥ 65 years iii) designing a risk assessment mechanism, based on the best practices developed in the aerospace sector, for patients with neurotoxic infection and POCD, that can be furtherly scalable in other medical contexts. iv) building an AI-based platform, following the example of the NSQIP risk calculator for cardiovascular postoperative complications, both for data collection and data processing, able to return an estimate of the risk of perioperative-related cognitive complications in elder patients undergoing major elective surgeries. Observational Clinical Trial The clinical trial will recruit a sample of 1685 patients in eight centres (about 250 patients per centre, considering also the drop-out rate) to be finalised in 24 months. The primary end point of the clinical trial is to evaluate if patients undergoing general anaesthesia for elective major surgeries lasting longer than 1 hour that have an history of COVID-19 (not an active SARS-CoV-2 infection) do have a higher risk to develop postoperative cognitive dysfunction (POCD)/delayed neurocognitive recovery (DNC) at 3 months and 6 months follow up after surgery. Secondary end point include: - Relationship between POCD/DNC with preoperative exposure to other neurotropic viruses: Herpes simplex virus (HS), Cytomegalovirus (CMV), and Epstein Barr virus (EBV). - Development -on the basis of collected data- of a software dedicated to calculating in the preoperative phase the risk for early postoperative delirium or POCD/PNDs. - Development of a conceptual model of "perioperative safety management": as in civil aviation traffic control, increasing the patients' perception of healthcare safety and quality. - Delivery of training to healthcare practitioners concerning the preoperative evaluation of POD risk and the identification of patients at risk.

Pain assessment in intensive care patients is a constant challenge. Approximately 50% to 80% of patients report pain at rest or during medical or nursing interventions (for example endotracheal suctioning, mobilization and rehabilitation, presence and care of invasive inputs, etc.). Obstacles to pain assessment and management are most often due to interference with communication due to impaired consciousness, airway support and connection to artificial pulmonary ventilation, or the effect of administered medication. Patients in intensive care are prone to delirium. Delirium can compromise patients' ability to verbalise pain for a variety of reasons (e.g. due to impaired attention, memory, thinking and language barriers). Also, pain and inadequate analgesia are risk factors for delirium. Pupillary reflex changes and their identification by automated pupillometry have yielded positive results regarding nociception assessment in adult and pediatric patients and in perioperative and postoperative care. At the same time, the response of these patients to opioid administration was investigated. The aim was to improve their analgesia. The aim of this study is to find out whether, there is an association between automated pupillometry and selected objective pain measurement scales in The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) positive patients after surgery.

(Background) Adults in intensive care units (ICU), especially elderly patients often suffer from a lack of sleep or frequent sleep disruptions due to physical, emotional stress such as pain, inflammation, and anxiety. Delirium, acute cognitive dysfunction, which result from sleep deprivation often leads to prolonged ICU stay and increase medical costs. Pharmacological and non-pharmacological interventions have been tried to improve the duration and quality of sleep and to maintain diurnal cycle. (Purpose) The aim of this study is to assess the efficacy of patient-driven interactive music intervention on sleep promotion in critically ill elderly adults. Delirium and urine/blood melatonin level will be assessed, too. In this study, randomized controlled trial for 50 elderly ICU patients who aged over 65 years in each group will be proceeded.

Delirium after cardiac surgery can occur in up to 50% of the patients and has been shown to be significantly associated with increased morbidity and mortality. Advanced age is a significant risk factor of delirium. Numerous studies have shown that sedation with high doses of Dexmedetomidine in the ICU reduces the incidence of postoperative delirium. On the other hand animal studies have shown neuroprotective effects of Dexmedetomidine by means of stimulating alpha2A-adrenoceptors. It is not clear whether the administration of a low dose Dexmedetomidine in cardiac surgery would have any neuroprotective effects by stimulating the alpha 2A-receptors and as such would decrease the incidence of postoperative delirium.
