Researchers developed a new scoring system, CAM-S, to measure delirium severity in older adults, which is associated with hospital mortality rates of up to 33% and estimated annual healthcare costs of over $182 billion. The study found that length of hospital stay increases with delirium severity, as well as mean hospital costs.
A new delirium severity score helps predict hospital outcomes in patients with delirium. The Confusion Assessment Method (CAM) scoring system is validated for predicting adverse outcomes, including prolonged hospital stay and functional decline. Additionally, a US survey shows that obesity contributes to the dramatic increase in diabet...

Delirium in older patients is frequently overlooked due to the lack of screening tools in emergency departments. The condition can lead to prolonged hospital stays, increased mortality rates, and a higher risk of developing dementia. Researchers call for the development of emergency department-specific screening instruments to improve ...
A novel role for S100β has been identified as a biomarker for delirium duration in critically ill patients, which may have implications for refining treatment in intensive care units. Delirium duration is associated with increased mortality rates, and higher levels of S100β on day 1 or day 8 are linked to longer delirium duration.
A Vanderbilt study found that 74% of patients with respiratory failure, cardiogenic shock, or septic shock developed delirium in the hospital, leading to dementia-like brain disease even a year after discharge. Cognitive deficits persisted for up to 12 months in both older and younger patients.

Researchers tested haloperidol, a commonly used antipsychotic, in 141 critically ill patients on artificial ventilation. The study found that haloperidol had no effect on reducing delirium or mortality rates, but may help reduce sedation requirements. Non-pharmacological interventions are more effective in preventing delirium.
A new two-minute assessment tool has been developed to help hospital staff identify patients at risk of developing delirium, a condition characterized by severe confusion and disorientation. The tool, termed AWOL, uses elements that can be assessed quickly in the fast-paced environment of a hospital.
A study found that nearly half of older adults undergoing surgery with general anesthesia developed delirium in the postanesthesia care unit (PACU), with 45% of patients experiencing delirium. Delirium is linked to decreased cognitive function and an increased risk of nursing home admission. The study suggests that even brief episodes ...
A team of doctors and nurses at Johns Hopkins Hospital implemented interventions to improve patient sleep quality, reducing delirium by 54% in ICU patients. The study suggests that simple measures can have a significant impact on patient outcomes and recovery from intensive care.
A new trauma program at St. Michael's Hospital has shown significant improvements in outcomes for elderly patients admitted for trauma. The program, which provides geriatric consultations within 72 hours of admission, has reduced the risk of delirium by 10% and decreased the likelihood of discharge to long-term care facilities.
A randomized controlled trial found that daily sedation interruption did not improve outcomes, including duration of mechanical ventilation, among critically ill patients. The study also revealed increased use of opioids and benzodiazepines in the interruption group.
Delirium is a common acute condition with significant short- and long-term effects on cognition and function. A systematic evidence review identified risks, prevention options, and prognoses related to delirium, emphasizing the need for effective management strategies.
Patients with Alzheimer's who suffered delirium episodes had a sharply increased rate of mental decline for up to five years after hospitalization compared to those without episodes. The study highlights the importance of recognizing and preventing delirium, which is estimated to cost the healthcare system billions annually.
A study published in the journal Brain found that episodes of delirium increase the risk of developing new dementia eight-fold in older patients. Delirium also worsens the severity of dementia and accelerates cognitive decline in those already diagnosed with dementia.
New research establishes a link between postoperative delirium and prolonged loss of cognitive function in cardiac surgery patients. Interventions to prevent delirium may help cardiac patients avoid long-term cognitive consequences.

Researchers developed a mouse model of delirium, finding that systemic inflammation triggers short-term memory disturbance, which is reversed by treatment with donepezil. The study reconciles two long-standing hypotheses, shedding light on the condition's causes and potential treatments.
A study at Duke University Medical Center confirms an association between sleep apnea and post-surgical delirium, a condition with serious health consequences. Researchers found that patients with obstructive sleep apnea were more likely to develop delirium after surgery.
A new study published in Infection Control and Hospital Epidemiology found that patients moved into isolation during hospitalization are nearly twice as likely to develop delirium. The researchers suggest that underlying illness may be the cause of this association.
A systematic review of delirium biomarkers found that clinicians are not using these chemical indicators to diagnose or treat patients with delirium. Biomarkers linked to delirium provide a window into the disease process, enabling better recognition and management of the condition.
A new national plan aims to improve care for patients with delirium, a poorly understood condition that affects millions of Americans. The plan outlines four goals: improving clinical care, educating healthcare providers, investing in research, and developing a network of delirium professionals.

The study highlights the need for nurses to be aware of the potential difficulties older adults may experience during disasters.
A review of 4,431 patients from six countries found that older adults with cognitive impairment often face challenges in emergency departments due to lack of assessment tools and inadequate care. The authors highlight the need for more research and development of a clinically relevant screening tool to address these issues.
A prospective study found that smoking significantly increases a woman's risk for peripheral artery disease (PAD), which can cause pain and discomfort. The study also suggests that smoking cessation reduces the risk, but even after 20 years of abstention, the risk remains elevated.
