Hypoactive delirium

Prevalence rates of delirium amount to 22.0% within acute-care settings. In contrast, 30-40% of patients with liver cirrhosis may develop hepatic encephalopathy, a condition that has been classified as a syndrome of delirium, based on recent pathophysiology findings. However, the prevalence of delirium in gastroenterology and hepatology units is unknown.The aims of the study were (i) to identify delirium prevalence rates in inpatients of gastroenterology/hepatology wards, (ii) to analyze the delirium motor subtype, and (iii) to assess associations between delirium and patient characteristics...

Postoperative delirium (POD) is a complicated and harmful clinical syndrome. Traditional behaviour analysis mostly focuses on static parameters. However, animal behaviour is a bottom-up and hierarchical organizational structure composed of time-varying posture dynamics. Spontaneous and task-driven behaviours are used to conduct comprehensive profiling of behavioural data of various aspects of model animals. A machine-learning based method is used to assess the effect of dexmedetomidine. Fourteen statistically different spontaneous behaviours are used to distinguish the non-POD group from the POD group...

OBJECTIVES: Postoperative delirium affects up to 50% of patients undergoing cardiac surgery. Delirium phenotypes are commonly divided into hyperactive and hypoactive, with hypoactive symptoms (reduced motor activity and withdrawal) often being overlooked due to their discreet character. Although the consequences of hypoactive delirium are severe, studies focusing on patients' experiences of hypoactive delirium are scarce. The aim of the study was to describe cardiac surgery patients' experiences of hypoactive delirium...

Delirium (or Acute Confusional State) refers to an acute alteration of attention, consciousness, and cognitive performance. Particularly the hypoactive subtype of delirium represents a diagnostic and clinical challenge. As symptoms of hypoactive delirium may overlap with the clinical picture present in dementia and depression, correct diagnostic differentiation can be challenging. In the absence of timely diagnosis and treatment, hypoactive delirium can last for several weeks. Apart from the health consequences for the patient, such a long course can stress caregivers and the family to their very limit...

BACKGROUND: Delirium is a common neuropsychiatric syndrome in hospitalized elderly patients and is associated with poor clinical outcomes. We aimed to determine the prevalence, recognition, risk factors, and course of delirium among hospitalized elderly (65 years of age or older) patients at Sultan Qaboos University Hospital (SQUH). METHODS: A prospective cohort study included 327 elderly patients (65 years of age or older) admitted to the medical wards at SQUH...

OBJECTIVE: To investigate the prevalence, risk factors, duration and outcome of delirium in intensive care unit (ICU) patients. METHODS: A prospective observational study was conducted for critically ill patients admitted to the department of critical care medicine, the Affiliated Hospital of Guizhou Medical University from September to November 2021. Delirium assessments were performed twice daily using the Richmond agitation-sedation scale (RASS) and confusion assessment method of ICU (CAM-ICU) for patients who met the inclusions and exclusion criteria...

PURPOSE: To determine the incidence and factors related to the presence of Delirium in children under 5 years of age hospitalized in the pediatric intensive care unit (PICU). DESIGN AND METHODS: Prospective observational study, through a convenience sampling. Fifty-two patients hospitalized in the PICU between 6 months and 5 years of age were included. The Preschool Confusion Assessment Method for the intensive care units (PSCAM-ICU) instrument was applied in its Spanish version...

Background: The development of major depressive disorder in patients at end of life often goes undiagnosed, as it is difficult to distinguish from preparatory grief and/or hypoactive delirium in this unique patient population. If this preliminary barrier of appropriate diagnosis is overcome, it can be quite difficult to properly select and adjust pharmacological therapy. Many well-established antidepressants take four to five weeks for maximal effectiveness (which may be far too long of a titration period for patients at end of life), have various contraindications to patients' comorbid chronic conditions (particularly patients with cardiovascular disease), or may simply be ineffective...

BACKGROUND: Delirium is one of the most common complications in critically ill children. Once delirium occurs, it will cause physical and psychological distress in children and increase the length of their ICU stay and hospitalization costs. Understanding the risk factors for delirium in critically ill children can help develop targeted nursing interventions to reduce the incidence of delirium. AIMS AND OBJECTIVES: To investigate the incidence and the risk factors of delirium in the paediatric intensive care unit (PICU)...

BACKGROUND: Delirium is a distressing condition often experienced by hospice in-patients. Increased understanding of current multidisciplinary care of delirium is needed to develop interventions in this setting. AIM(S): To explore hospice staff and volunteers' practice, its influences and what may need to change to improve hospice delirium care. DESIGN: Qualitative interview study using behaviour change theory from a critical realist stance...

Many critically ill patients suffer from delirium which is associated with significant morbidity and mortality. There is a paucity of data about the incidence, symptoms, or treatment of delirium in the pediatric intensive care unit (PICU). Risk factors for delirium are common in the PICU including central nervous system immaturity, developmental delay, mechanical ventilation, and use of anticholinergic agents, corticosteroids, vasopressors, opioids, or benzodiazepines. Hypoactive delirium is the most common subtype in pediatric patients; however, hyperactive delirium has also been reported...

BACKGROUND: Delirium detection is challenging due to the fluctuating nature and frequent hypoactive presentation. This study aimed to determine an optimal strategy that detects delirium with higher sensitivity but lower effort in older patients admitted to the intensive care unit (ICU) after surgery. METHODS: This was a secondary analysis of the database from a randomized trial. Seven hundred older patients (aged ≥65 years) who were admitted to the ICU after elective noncardiac surgery were enrolled...

OBJECTIVE: Delirium is dangerous and a predictor of poor patient outcomes. We have previously reported the utility of the bispectral EEG (BSEEG) with a novel algorithm for the detection of delirium and prediction of patient outcomes including mortality. The present study employed a normalized BSEEG (nBSEEG) score to integrate the previous cohorts to combine their data to investigate the prediction of patient outcomes. We also aimed to test if the BSEEG method can be applicable regardless of age, and independent of delirium motor subtypes...

BACKGROUND: Delirium is an acute confusion state that is common and costly. According to different clinical manifestations, delirium can be divided into three subtypes: hyperactive, hypoactive and mixed. Subtype research has become a necessary branch. However, it is difficult to record all the changes in subtype research. METHODS: Publications on delirium subtypes in the Web of Science Core Collection (WOSCC) were identified and analyzed by visualization software VOSviewer and CiteSpace...

Delirium, a common form of acute brain dysfunction, is associated with increased morbidity and mortality, especially in older patients. The underlying pathophysiology of delirium is not clearly understood, but acute systemic inflammation is known to drive delirium in cases of acute illnesses, such as sepsis, trauma, and surgery. Based on psychomotor presentations, delirium has three main subtypes, such as hypoactive, hyperactive, and mixed subtype. There are similarities in the initial presentation of delirium with depression and dementia, especially in the hypoactive subtype...

BACKGROUND: Delirium is a common, under-recognized, and often fatal condition in critically ill patients, characterized by acute disorder of attention and cognition. The global prevalence varies with a negative impact on outcomes. A paucity of Indian studies exists that have systematically assessed delirium. OBJECTIVE: A prospective observational study designed to determine the incidence, subtypes, risk factors, complications, and outcome of delirium in Indian intensive care units (ICUs)...

OBJECTIVES: The assessment of prevalence of delirium in advanced cancer patients admitted in hospice centre and outcome after palliative intervention. The possible related risk factors for development of delirium. MATERIAL AND METHODS: This was prospective analytic study done at hospice centre attached with tertiary cancer hospital in Ahmedabad during August 2019 - July 2021. This study was approved by the Institutional Review Committee. We selected patients according to following inclusion criteria (all patient admitted to hospice centre above 18 years, with advance cancer disease and on best supportive care) and exclusion criteria (Lack of informed consent, Inability to participate in study due to mentally retard or coma)...

BACKGROUND: The course of the postoperative period in patients who underwent surgical interventions is often complicated by cerebral disorders. The aim of the research was to examine the clinical and psychopathological, pathopsychological, clinical and dynamic features of psychotic disorders, occurring after surgical interventions conducted using general anesthesia in patients of senile age with concomitant psychiatric pathology of the defect and organ register. SUBJECTS AND METHODS: The study relied on examination of 67 subjects who had psychotic disorders after surgical interventions conducted using inhalation anesthesia...

BACKGROUND: This study aimed to describe the relationship between the different levels of intraoperative mean arterial blood pressure (MAP) and postoperative delirium in elderly patients undergoing gastrointestinal laparoscopic surgery. MATERIALS AND METHODS: This prospective controlled clinical trial enrolled 116 patients aged 65 to 85 years who underwent gastrointestinal laparoscopic surgery. These patients were randomized 1:1 to a MAP goal of 65 to 85 mmHg (L group) or an 86 to 100 mmHg (H group)...

BACKGROUND: The prognostic implication of delirium subtypes in critically ill medical and surgical patients is scarcely investigated. The objective was to determine how delirium subtypes are associated with hospital mortality and other clinical outcomes. METHODS: We performed a secondary analysis on data from a prospective multicenter study aimed at implementation of delirium-oriented measures, conducted between 2012 and 2015 in The Netherlands. We included adults (≥ 18 years) admitted to the medical or surgical intensive care unit (ICU)...
