Delirium is associated with low levels of upright activity in geriatric inpatients-results from a prospective observational study.

Background: Delirium is common in geriatric inpatients and associated with poor outcomes. Hospitalization is associated with low levels of physical activity. Motor symptoms are common in delirium, but how delirium affects physical activity remains unknown.

The delirium screening tool 4AT in routine clinical practice: prediction of mortality, sensitivity and specificity.

Purpose: Delirium is common and associated with poor outcomes, partly due to underdetection. We investigated if the delirium screening tool 4 A's test (4AT) score predicts 1 year mortality and explored the sensitivity and specificity of the 4AT when applied as part of a clinical routine.

Methods: Secondary analyses of a prospective study of 228 patients acutely admitted to a Medical Geriatric Ward.

Delirium motor subtypes and prognosis in hospitalized geriatric patients - A prospective observational study.

Objective: Delirium is common and associated with poor outcomes. Hypoactive motor subtype may predict worse outcome than no-subtype, hyperactive and mixed delirium, but uncertainty remains due to heterogeneity of results and subtyping tools. Other prognostic aspects across delirium motor subtypes are understudied.

Delirium and cognitive impairment among older patients in Norwegian emergency departments.

Background: Delirium is common and underdiagnosed among patients in hospitals, and is associated with complications, increased mortality, onset of dementia and need for nursing home care. Cognitive impairment from other causes is also common among hospitalised elderly people and is a key risk factor for delirium. Since no relevant prevalence studies have been undertaken in Norwegian hospitals, we investigated the prevalence of delirium among elderly patients in Norwegian emergency departments on World Delirium Awareness Day, 14 March 2018.

Motor activity across delirium motor subtypes in geriatric patients assessed using body-worn sensors: a Norwegian cross-sectional study.

Objectives: It remains unclear if geriatric patients with different delirium motor subtypes express different levels of motor activity. Thus, we used two accelerometer-based devices to simultaneously measure upright activity and wrist activity across delirium motor subtypes in geriatric patients.

Design: Cross-sectional study.

Environmental factors and risk of delirium in geriatric patients: an observational study.

Background: Patients with delirium have increased risk of death, dementia and institutionalization, and prognosis differs between delirium motor subtypes. A few studies have identified associations between environmental factors like room-transfers and time spent in the emergency department (ED) and delirium, but no studies have investigated if environmental factors may influence delirium motor subtypes. We wanted to explore if potentially stressful events like ward-transfers, arriving ED at nighttime, time spent in ED and nigthttime investigations were associated with development of delirium (incident delirium) and delirium motor subtypes.

Physical activity among hospitalized older adults - an observational study.

Background: Low level of physical activity is common among hospitalized older adults and is associated with worse prognosis. The aim of this paper is to describe the pattern and level of physical activity in a group of hospitalized older adults and to identify factors associated with physical activity.

Methods: We measured physical activity on day three after admission using accelerometer based activity monitors and time in upright position as outcome measure.

[COX-2 inhibitors--one step forward and two steps back].

Background: Selective cyclooxygenase-2 (COX-2) inhibitors are widely used. They have no advantages in terms of efficacy, and it is not documented that they cause fewer adverse effects than conventional NSAIDs.

Material And Methods: The adverse effects of rofecoxib, celecoxib and other NSAIDs are reviewed.
