Filter by:The long-term goal of this research program is to improve understanding of the mechanistic link between Alzheimer's disease (AD) neuropathology, acute delirium, and cognitive impairment following acute respiratory failure. In this pilot study, the study team will establish a prospective cohort of older patients with acute respiratory failure and obtain data on delirium duration, AD imaging and CSF biomarkers, and cognitive outcomes following critical illness.
Dexmedetomidine（DEX）is a potent and highly selective α 2 adrenergic receptor agonist. It has the pharmacological effects of sedation, hypnosis, analgesia, anti-sympathetic and neuroprotective. Its sedative effect is similar to normal sleep, and easy to wake up. DEX is widely used clinically because of its advantages and acceptable side effects. The best clinical use of DEX is uncertain, including intravenous, intramuscular, oral, intralnasal and sublingual administration. Its clinical recommended use is intravenous load infusion for more than 10 minutes, followed by continuous infusion. However, the clinical recommended usage is inconvenient, time-consuming and other shortcomings, for the growing popularity of daytime surgery, will inevitably affect the operation process and turnover. If a suitable dose range of DEX can be found for a single intravenous injection to achieve clinical efficacy quickly without significant hemodynamic effects, this will improve the patient's postoperative recovery. We will speed up the utilization and turnover of medical resources. The aim of this study was to investigate the optimal dosage of DEX for single intravenous injection.
The overlap of depression and delirium as geriatric syndromes present in elderly patients with hospital admission due to hip fracture has been previously studied. Nevertheless, the relationships between these two clinical processes and other geriatric syndromes, especially malnutrition, have not been studied. For this reason, a prospective cohort study has been designed to know the differences in the incidence of geriatric syndromes during hospital admission due to hip fracture in patients with and without risk of malnutrition.
Delirium is a disturbance in consciousness with reduced ability to focus, sustain, or shift attention that occurs over a short period of time and tends to fluctuate over the course of the day. 50% to 81.7% had delirium during their ICU hospitalization. Delirium is associated with increased physical restraint, ventilation use, length of ICU stay, and mortality. However, there is no established delirium care pathway in target hospital. Chen et al. (2014) demonstrated that structured assessment stations with immediate feedback may improve overall learning efficiency over an EBP workshop alone. However, no published delirium care education study has used OSCEs as an intervention for healthcare professionals. The aim is to evaluate the effects of implementing a Scenario-based education intervention, including objective structured clinical examinations (OSCEs) on delirium care among healthcare professionals. This is a knowledge translation research, builds on eight years of delirium care research in University of Wollongong, Australia. The research will be undertaken at ICUs in a medical center in northern of Taiwan. There are two phases: (1) systematic review to identify delirium screen tool, and (2) a randomized controlled trial was conducted to determine the effects of implementing a Scenario-based education intervention, including OSCE (experimental group), and on-line education only (control group) focused on recognition and management of delirium. The hypothesis is: Scenario-based education intervention, including OSCE can increase the competence and self-efficacy among healthcare professionals in delirium care.
Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common after surgeries in the elderly, especially after cardiothoracic surgery. These conditions are associated with adverse short- and long-term outcomes. Multiple conditions in the perioperative period have been proposed as risk factors of POD and POCD. Incidences vary across institutions due to differences in screening and diagnostic tools.
Delirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. Continuous femoral nerve block is frequently used for postoperative analgesia after total knee arthoplasty. The investigators hypothesize that dexmedetomidine, when combined with ropivacaine for continuous femoral nerve block, can reduce the incidence of delirium and improve the long-term outcome in elderly patients after total knee arthroplasty.
Delirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. The investigators hypothesize that, for elderly patients after orthopedic surgery, dexmedetomidine supplemented intravenous analgesia can reduce the incidence of delirium and improve the long-term outcomes.
The EuRIDICE trial will study whether haloperidol as a first line treatment for ICU delirium reduces delirium duration (and severity). Adverse outcomes typically associated with delirium will also be studied and include long term cognition, functional outcome and quality of life. Further, patient and family experiences and cost-effectiveness will be assessed. Finally, safety concerns associated with the use of haloperidol in this vulnerable population will be studied.
Older patients (i.e.; ≥ 65 years) with a hip fracture, and who are admitted to orthopedics for surgery are particularly at risk of adverse health events such as delirium, recurrent falls and prolonged hospital stay caused by their frailty status. The Hospital Elder Life Program (HELP) is a comprehensive inpatient-care program that ensures optimal care for older adults in the hospital and, thus, might reduce the incidence of postoperative adverse health events. The overall objective of this study is to examine in a quantitative fashion the effects of the HELP program on adverse health events in geriatric inpatients admitted to the orthopedic ward at JGH for surgery after a hip fracture.
Delirium is an acutely occurred and fluctuating cerebral dysfunction characterized with inattention, altered consciousness, cognitive decline and/or abnormal perception. It is common in the elderly after cardiac surgery and is associated with worse outcomes. Causes leading to delirium are multifactorial but sleep disturbances remains an important one. In previous studies, sedative-dose dexmedetomidine improves sleep quality in ICU patients with mechanical ventilation; and low-dose dexmedetomidine improves sleep quality in postoperative patients without mechanical ventilation. In recent studies of elderly after noncardiac surgery, night-time infusion of low-dose dexmedetomidine reduces delirium and improves 2-year survival. The investigators hypothesize that, for elderly patients after cardiac surgery, night-time infusion of dexmedetomidine may also improve sleep quality, reduce delirium development and improve 2-year survival.
