Triple Sleep-Promotion Protocol for Delirium Prevention in Intensive Care Patients

Delirium is a common complication in intensive care units (ICUs) and may be associated with sleep disruption and frequent nighttime disturbances. This randomized controlled trial will evaluate whether a multicomponent nighttime sleep-promotion intervention, called the Triple Sleep-Promotion Protocol, can reduce the occurrence of new-onset delirium in adult ICU patients. The study is being conducted in four ICUs in Türkiye. Eligible patients who do not have delirium at the beginning of the study will be randomly assigned to either the intervention group or the control group. The intervention includes clustering nighttime nursing care, offering an eye mask and earplugs during protected sleep periods, and reducing avoidable nighttime light and noise whenever clinically feasible. Patients in the control group will receive usual ICU care. Patient safety and clinically necessary care will take priority over all sleep-promotion procedures. Participants will be followed during their ICU stay for up to five days. Delirium will be assessed twice daily using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Nighttime sleep quality will also be assessed each morning using the Richards-Campbell Sleep Questionnaire. The primary aim is to determine whether the Triple Sleep-Promotion Protocol reduces the incidence of new-onset delirium compared with usual ICU care.

Multi-Component Delirium Prevention Bundle in Older Cardiac Intensive Care Unit Patients

The goal of this randomized controlled clinical trial is to learn whether a structured delirium prevention protocol can reduce the occurrence of delirium in older adults admitted to the cardiac intensive care unit (CICU). The study will include participants aged 70 years and older who are hospitalized in the CICU with acute cardiac conditions. The main questions it aims to answer are: Does a structured non-pharmacologic delirium prevention protocol lower the incidence of delirium compared with usual care in older CICU patients? Does this protocol improve short- and long-term clinical outcomes, such as major adverse cardiac events (MACE), functional decline, and cognitive impairment? Researchers will compare participants randomly assigned to receive the delirium prevention protocol (intervention group) with participants receiving usual CICU care (control group) to see if the protocol leads to fewer episodes of delirium and better clinical and functional outcomes. Participants will: Be randomly assigned to the intervention group or the control group. Undergo daily delirium screening using the CAM-ICU tool. Be evaluated by an independent geriatrician who is not the principal investigator, and who will perform all clinical and geriatric assessments external to the treating CICU team. In the intervention group, receive a structured prevention protocol that includes: daily pain assessment using the VAS scale and age-appropriate analgesia as needed, avoiding benzodiazepines when possible, use of earplugs and eye masks at night, early mobilization including bedside cycling exercises, and support for vision and hearing (use of glasses and hearing aids) and family presence overnight. In the control group, receive usual CICU care, including delirium screening with CAM-ICU according to unit practice.

Exploring the Effectiveness of Intelligent Audiovisual Interventions in Delirium, Agitation, and Pain Among Middle Aged and Elderly Patients in Emergency Intensive Care Units: A Quasi-Experimental Study

The goal of this nonrandomized, quasi-experimental clinical trial is to evaluate whether an intelligent audiovisual intervention can prevent delirium and reduce delirium severity, agitation, and pain among adults aged 55 years or older admitted to an emergency intensive care unit (EICU). The main questions it aims to answer are: Does the intelligent audiovisual intervention reduce the incidence and severity of delirium compared with routine care? Does the intervention improve agitation and pain scores compared with routine care? Researchers will compare participants receiving the intelligent audiovisual intervention plus routine care with participants receiving routine care alone. Participants will be assigned according to the week of EICU admission: those admitted during odd-numbered weeks will receive the intervention, while those admitted during even-numbered weeks will receive routine care. Participants in the intervention group will: View a structured audiovisual program containing a prerecorded message from a family member, current date and weather information, and images of the area surrounding the hospital. Receive the intervention for 2 minutes per session, 3 times daily for 2 consecutive days, beginning within 24 hours after EICU admission. Participants in both groups will undergo assessments of delirium, agitation, and pain 3 times daily for 2 consecutive days. Delirium incidence and severity will be assessed using the Confusion Assessment Method for the Intensive Care Unit-7 (CAM-ICU-7). Agitation will be evaluated using the Richmond Agitation-Sedation Scale (RASS), and pain will be assessed using either the Numerical Rating Scale (NRS) or the Face, Legs, Activity, Cry, and Consolability (FLACC) scale.

ICU Delirium Playbook Training Study for ICU Nurses

Delirium is a common and serious acute neurocognitive disorder among critically ill patients, affecting up to 50% of intensive care unit (ICU) patients and up to 80-90% of those receiving invasive mechanical ventilation. It is associated with increased mortality, prolonged ICU and hospital length of stay, long-term cognitive impairment, higher healthcare costs, and reduced quality of life for patients and their families. Despite the availability of validated screening tools such as the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), delirium remains underrecognized and undertreated in routine clinical practice, largely because of inadequate healthcare professional education and inconsistent implementation of evidence-based recommendations. Nurses play a central role in the prevention, early detection, and management of delirium, making targeted educational interventions essential to improve clinical practice. The ICU Delirium Playbook is a multimedia educational program developed by the University of California, San Diego, consisting of brief instructional videos and realistic clinical scenarios designed to improve nurses' knowledge and confidence in delirium assessment and management. The aim of this quasi-experimental pre-post study is to evaluate the effectiveness of the ICU Delirium Playbook among intensive care nurses at Pisa University Hospital. The primary objective is to determine whether participation in the educational program improves nurses' knowledge of delirium. Secondary objectives are to evaluate participants' satisfaction with the training, assess changes in clinical attitudes and behaviors related to delirium care, validate the Italian version of the behavioral assessment questionnaire, and explore the impact of the educational intervention on patient outcomes, including the frequency of delirium recognition and the duration of delirium episodes. The study will be conducted in a single center using a pre-intervention and post-intervention design. Before the educational intervention, participating nurses will complete questionnaires evaluating delirium knowledge, attitudes, and clinical behaviors. During the same period, retrospective and prospective clinical data will be collected from medical records of adult patients admitted to the Cardio-Thoracic-Vascular Intensive Care Unit, including delirium assessment and diagnosis. Following baseline data collection, nurses will attend the ICU Delirium Playbook educational session, lasting approximately four hours. After completion of the videos, nurses will repeat the same questionnaires, and patient clinical data will be collected again during a six-month post-intervention period. The study is based on Kirkpatrick's Four-Level Model for training evaluation, assessing participants' reaction to the educational intervention, learning outcomes, behavioral changes in clinical practice, and the effects on patient care. It is expected that the intervention will improve nurses' knowledge and evidence-based management of delirium, increase the recognition of delirium in ICU patients. The findings of this study will provide evidence regarding the effectiveness of the ICU Delirium Playbook in the Italian critical care setting and may support the implementation of standardized delirium education programs in intensive care units.

Physical Restraints in Intensive Care Unit Patients

The use of physical restraints is common practice in Intensive Care Units (ICU). This medically prescribed procedure requires full attention of medical and paramedical teams for its implementation, monitoring and ending, as a major restriction of patients\' individual freedom. French highest authority for health has defined, for geriatrics and psychiatric units, ten criteria of good practice for physical restraints' use. Routine practice reports critically ill patients' safety as main reason of use. This decision, often left to the sole discretion of nurses, varies according to their own representation of this risk, and depends on several factors: seniority in ICU, nurse to patient ratio and personal workload. In order to reduce practices subjectivity and heterogeneity, we have developed a decision-making tool for physical restraints implementation. This tool is based on objective scales used on a daily basis concerning neurological status (Richmond Agitation-Sedation Scale (RASS) and Confusion Assessment Method for the ICU (CAM-ICU)). Disorientation or delirium can lead to severe incidents by promoting accidental removing of important devices such as arterial of venous line, drains among others. However, physical restraints are recognized as a major cause of delirium and agitation. Critically ill patients require rigorous evaluation of organ dysfunctions necessitating adequate invasive equipments, with associated risks of unexpected removal or alteration. Such events could urge caregivers to use physical restraints. Based on recent literature, about a third of ICU patients are restrained, and accidental deconditioning is mainly observed within these particular patients. In addition, three categories of patients have been defined according to the invasive nature of their equipment and therefore according to the risk associated with an unexpected withdrawal. Finally, presence of patient\'s family and their adherence to its surveillance were also implemented into the tool. Main study objective is to jointly investigate effectiveness and tolerance of a decision-making tool guiding physical restraints use in ICU patients.

Trazodone vs. Quetiapine for the Treatment of ICU Delirium

This is a single-center, prospective observational pilot study. The objective of this study is to evaluate the effectiveness of trazodone as compared to quetiapine, in the management of ICU delirium in adult (\>=18 years old) surgical and medical ICU patients. The investigators will compare outcomes such as delirium duration, delirium-free days, coma-free days, in-hospital mortality, 28-day mortality, hospital length of stay (LOS), ICU LOS, mechanical ventilator days, complications, adverse effects, rescue medication use, delirium symptom severity, sleep duration, and sleep quality among participants receiving trazodone or quetiapine. The investigators hypothesize participants receiving trazodone will be associated with a shorter duration of delirium, decreased delirium severity, and improved sleep quality compared to participants receiving quetiapine.

Phenobarbital for Agitated Delirium

The goal of this clinical trial is to test whether the medication phenobarbital is as effective for treating agitated delirium among adult patients admitted to the intensive care unit. Agitated delirium is a condition involving confusion and impulsiveness which is dangerous to both patients and healthcare providers. The main questions this trial aims to answer include: * Can phenobarbital decrease the amount of time patients with agitated delirium spend in the intensive care unit and the hospital? * Does phenobarbital decrease the amount of additional calming medications patients with agitated delirium need? Researchers in this study will compare phenobarbital to other medications commonly used to treat agitated delirium. Participants will be monitored closely to make sure they remain safe and to measure how well their agitation and confusion are managed while they are in the ICU.

Using Virtual Reality to Improve Medical Training

As the U.S. population ages, future physicians must be prepared to care for older adults with multiple health conditions and complex needs. This study will test whether cinematic virtual reality (VR)-an immersive, interactive learning tool-is more effective than traditional lectures in helping medical students learn about geriatric care. Students who complete the VR training will experience realistic patient scenarios that show what can go wrong in medical care and learn how to apply osteopathic principles to improve outcomes. Researchers will compare students' performance on a clinical skills assessment and explore their experiences with the VR training. The goal is to determine whether cinematic virtual reality can better prepare students for residency and improve their ability to provide compassionate, high-quality care for older adults.

Lorazepam for Delirium Prevention in Critically Ill Patients With High Anttila-Index

Delirium is a neuropsychiatric syndrome characterized by cognitive and attentional deficits, circadian rhythm, emotional and psychomotor dysregulation. It is frequently encountered in patients admitted to an Intensive Care Unit (ICU) with a prevalence of 20-80% and associated with higher morbidity and mortality, prolonged hospitalization and cognitive impairment after hospitalization. Alcoholism is an important risk factor that favors the development of delirium and a common comorbidity in patients admitted to the ICU. Patients with alcohol use disorders can develop a withdrawal syndrome after cessation of alcohol consumption. The most severe form of alcohol withdrawal is the alcohol withdrawal delirium, which is characterized by a profound state of confusion. Early recognition and treatment significantly diminish severe complications of alcohol withdrawal delirium, including mortality. The common pharmacological prevention and therapy of alcohol withdrawal syndrome is the administration of benzodiazepines, which have the potential to prevent or mitigate alcohol withdrawal delirium. In the ICU setting the diagnosis of alcoholism based on self-report can be unreliable and complicated by acute illness. The Anttila-Index is a parameter calculated from the carbohydrate-deficient transferrin and the gamma-glutamyltransferase. It has a high sensitivity and specificity for excessive alcohol consumption. Therefore, the Anttila-Index of patients admitted to the ICU could help identify patients at risk for developing delirium due to alcoholism or due to alcoholism in combination with other risk factors. Schreiber et al. recently (October 2023) found significantly higher Anttila-Index in patients with delirium on a medical ICU. The investigators postulate that this also applies to the patients admitted to the mixed (medical and surgical) ICU at the University Hospital Basel (USB), since surgery is an additional crucial risk factor for delirium development. Hypothesis: ICU delirium can be reduced by careful preventive administration of lorazepam in patients admitted to the ICU with an Anttila-Index at or above the cutoff value of four.

Delirium and Heart Failure

Biomarkers such as Systemic Immune-Inflammation Index (SII) and TG/Glucose Ratio (TyG) have shown promise in predicting delirium, reflecting the roles of inflammation and metabolic disturbances in its pathophysiology. This study aims to compare the predictive value of SII and the TyG ratio among other chemical and physiological biomarkers for diagnosing delirium and detecting its severity in older adults with heart failure. These biomarkers reflect different pathophysiological pathways implicated in delirium, including inflammation, cardiovascular stress, and metabolic dysfunction. By evaluating their individual and combined predictive abilities, this research seeks to identify potential tools for early identification of patients at high risk for delirium

Point-of-Care AI Assistance and Critical Care Outcomes: A Randomized Trial

This is a prospective, unmasked, randomized, multicenter clinical trial evaluating the impact of point-of-care large language model (LLM)-based decision support on diagnostic accuracy and clinical outcomes in adult medical intensive care unit (MICU) patients. Consecutive adult ICU admissions at participating community hospitals (initially MetroWest Medical Center and St. Vincent Hospital) will be screened for eligibility. Eligible patients will be randomized 1:1 to standard care or an AI-assisted group. In both arms, initial evaluation and management will follow usual practice. For patients randomized to AI assistance, de-identified admission data (history and physical, labs, imaging reports, and other relevant documentation) will be formatted and submitted to a state-of-the-art LLM (ChatGPT-5) at the time of admission. The AI-generated differential diagnosis and therapeutic recommendations will be provided to the admitting team for consideration. For the standard care arm, LLM output will be generated but not shared with clinicians. After discharge, a masked chart review will determine the "ground truth" primary diagnosis and extract outcomes including: Primary Outcome - a composite of medical errors (from time of ICU admission through day 7 of ICU stay, or ICU discharge, whichever comes first); Secondary Outcomes - 90-day mortality, ICU and hospital length of stay, and ventilator-free days.

Clinical Trial Protocol: Alzheimer's Dementia Underlying Encephalopathy

The goal of this clinical trial is to determine if utilizing the Quest AD-Detect blood test, while patient's are hospitalized for a cognitive diagnosis (such as delirium or encephalopathy), will result in an earlier diagnosis of underlying Alzheimer's disease. * Will this blood test have the ability to distinguish between Alzheimer's disease and other causes of cognitive impairment in the inpatient setting? * Neurology Clinic will complete a 6-month post-hospitalization follow up with patients who have had the Quest AD-Detect Alzheimer's Disease blood test completed while they were inpatient to discuss the risk assessment portfolio
