Objective: Nursing instruments have the potential for daily screening of delirium; however, they have not yet been evaluated. Therefore, after assessing the functional domains of the electronic Patient Assessment - Acute Care (ePA-AC), this study evaluates the cognitive and associated domains.Methods: In this prospective cohort study in the intensive care unit, 277 patients were assessed and 118 patients were delirious. The impacts of delirium on the cognitive domains, consciousness and cognition, communication and interaction, in addition to respiration, pain, and wounds were determined with simple logistic regressions and their respective odds ratios (ORs).Results: Delirium was associated with substantial impairment throughout the evaluated domains. Delirious patients were somnolent (OR 6), their orientation (OR 8.2-10.6) and ability to acquire knowledge (OR 5.5-11.6) were substantially impaired, they lost the competence to manage daily routines (OR 8.2-22.4), and their attention was compromised (OR 12.8). In addition, these patients received psychotropics (OR 3.8), were visually impaired (OR 1.8), unable to communicate their needs (OR 5.6-7.6), displayed reduced self-initiated activities (OR 6.5-6.9) and challenging behaviors (OR 6.2), as well as sleep-wake disturbances (OR 2.2-5), Furthermore, delirium was associated with mechanical ventilation, abdominal/thoracic injuries or operations (OR 4.2-4.4), and sensory perception impairment (OR 3.9-5.8).Significance Of Results: Delirium caused substantial impairment in cognitive and associated domains. In addition to the previously described functional impairments, these findings will aid the implementation of nursing instruments in delirium screening. [ABSTRACT FROM AUTHOR]

This study aimed to determine the 1-year prevalence of delirium and the impact of hospitalization characteristics on delirium across 34 services. In this prospective cohort study of elderly in-patients (>65 years, N = 10,261), delirium was determined with the Delirium Observation Screening Scale (DOS) and the Intensive Care Delirium Screening Checklist (ICDSC) in a single sample over one year. We calculated univariate and multiple logistic regression analyses to understand the power of association between delirium, 34 services, sociodemographic, and admission/discharge factors. The prevalence of delirium across all included services was 32%. The odds of developing delirium was highest for intensive care units (ICU, 83.3%, OR 12.34), high for intermediate care units (IMC, 39.8%, OR 1.42) and medical services (34.2%, OR 1.19), and lower for surgical services (28.7%, OR 0.72). Compared with patients without delirium, patients with delirium were older (76.6 vs. 75 years), hospitalized twice as long (14.3 vs. 7.7 days), more commonly had pre-existent dementia (OR 11.98), and were more likely to die in-hospital (OR 24.20) and be admitted from (OR 2.75–2.97) and discharged to institutions (OR 1.66–3.97). This study elaborated on the 1-year prevalence of delirium across 34 services and confirmed previous pooled findings in addition to providing new insights regarding the course of hospitalization in elderly patients. • Delirium in elderly inpatients across 34 services in single sample • Prevalence of delirium, impact of hospitalization characteristics • Delirium highest in intensive care units, lowest in surgical services • Delirium in elderly admitted from institutions and emergencies more frequently • Delirious elderly hospitalized longer, institutionalized, deceased more commonly [ABSTRACT FROM AUTHOR]

Objective: Nursing assessments have been recommended for the daily screening for delirium; however, the utility of individual items have not yet been tested. In a first step in establishing the potential of the electronic Patient Assessment-Acute Care (ePA-AC) as such, the impact of delirium on the functional domains was assessed.Method: In this prospective observational cohort study, 277 patients were assessed and 118 patients were delirious. The impact of delirium on functional domains of the ePA-AC related to self-initiated activity, nutrition, and elimination was determined with simple logistic regressions.Results: Patients with delirium were older, sicker, were more commonly sedated during the assessment, stayed longer in the intensive care unit (ICU) and floors, and less commonly discharged home. A general pattern was the loss of abilities and full functioning equivalent to global impairment. For self-initiated mobility, in and out of the bed sizable limitations were noted and substantial inability to transfer caused friction and shearing. Similarly, any exhaustion and fatigue were associated with delirium. For self-initiated grooming and dressing, the impairment was greater in the upper body. Within the nutritional domain, delirium affected self-initiated eating and drinking, the amount of food and fluids, energy and nutrient, as well as parenteral nutrition requirement. In delirious patients, the fluid demand was rather increased than decreased, tube feeding more often required and dysphagia occurred. For the elimination domain, urination was not affected - of note, most patients were catheterized, whereas abilities to initiate or control defecation were affected.Significance Of Results: Delirium was associated with sizable impairment in the level of functioning. These impairments could guide supportive interventions for delirious patients and perspectively implement nursing instruments for delirium screening. [ABSTRACT FROM AUTHOR]
