Background: Older adults comprise a growing proportion of the United States population that is at risk for burns. However, few studies have examined cognitive function in this patient population.
Objective: The purpose of this study was to measure the prevalence and incidence of dementia and delirium in older adults admitted for burn injuries.
Methods: This was an Institutional Review Board-approved, retrospective study of all patients 65 years and older admitted to the University of North Carolina Jaycee Burn Center from 2005-2015. Data extracted from the medical records included patient demographics, characteristics of the burn injury, incidence of delirium, incidence of psychiatric consultation, diagnosis of dementia, disposition, and mortality. The primary outcomes of interest were the prevalence and incidence of dementia and delirium. Secondary outcomes included length of stay and cost of hospitalization.
Results: A total of 392 patients were included. These patients had a median age of 74 years and a median total body surface area burn of 7%. On admission, 44 patients (11%) had a diagnosis of dementia. An additional 28 patients were diagnosed with dementia during hospitalization for a total of 72 patients (18%); 154 patients (39%) were diagnosed with delirium. After controlling for burn severity, dementia and delirium were significantly associated with length of stay, incidence of psychiatry consultation, and discharge to a skilled nursing facility.
Conclusions: Physicians should have high suspicion for dementia and delirium in older patients admitted for burn injuries. Dementia and delirium are associated with morbidity in older patients with burn injuries.

Rocking Motion Therapy for Delirious Patients in the ICU: A Multicenter Randomized Clinical Trial.

November 2024
Department of Intensive Care, Copenhagen University Hospital, Copenhagen, Denmark.
Objectives: Rocking motion therapy has been shown to calm people with dementia but has never been investigated in delirious patients in the ICU. The aim of this clinical trial was to investigate the efficacy and safety of a rocking motion vs. nonrocking motion chair on the duration of delirium and intensity of agitation in ICU patients with delirium.

Objectives: Neurocritically ill patients are at high risk for developing delirium, which can worsen the long-term outcomes of this vulnerable population. However, existing delirium assessment tools do not account for neurologic deficits that often interfere with conventional testing and are therefore unreliable in neurocritically ill patients. We aimed to determine the accuracy and predictive validity of the Fluctuating Mental Status Evaluation (FMSE), a novel delirium screening tool developed specifically for neurocritically ill patients.

Background: Postoperative delirium (POD) is a common complication after major surgery and is associated with poor outcomes in older adults. Early identification of patients at high risk of POD can enable targeted prevention efforts. However, existing POD prediction models require inpatient data collected during the hospital stay, which delays predictions and limits scalability.

: Postoperative delirium (POD) is a common surgical complication that increases hospital stay duration, hospitalization costs, readmission rates and mortality. This study aims to describe the incidence of POD in an elderly patient population and to investigate pain assessment as a risk factor for postoperative confusion. Additionally, we aim to determine a predictive model for POD.
