Delusions and Hallucinations Are Associated With Greater Severity of Delirium.

Background: The 3 core domains of delirium (cognitive, higher level thinking, circadian) do not include the less common noncore psychotic symptoms. However, psychosis might inform about perturbations of neural circuitry, outcomes, or suggest tailored clinical management.

Objective: We assessed relationships between psychosis and other characteristics of delirium in patients without dementia or antipsychotics treatment.

Delirium Phenotype by Age and Sex in a Pooled Data Set of Adult Patients.

The authors aimed to evaluate whether the clinical phenotype of delirium differs if dichotomized either by sex or age (cutoff age, 65 years old) in a pooled sample of 406 nondemented adult patients with delirium as defined by DSM-IV criteria. Delirium characteristics were measured with the Delirium Rating Scale-Revised-98 (DRS-R-98). DRS-R-98 items were subgrouped to represent subscores representing the three core domains of delirium (cognitive, higher-order thinking, and circadian), noncore accessory symptoms (psychotic and affective), and diagnostic characteristics (temporal onset, fluctuation, and physical disorder).

Confirmatory Factor Analysis of the Delirium Rating Scale Revised-98 (DRS-R98).

Principal components analysis applied to the Delirium Rating Scale-Revised-98 contributes to understanding the delirium construct. Using a multisite pooled international delirium database, the authors applied confirmatory factor analysis to Delirium Rating Scale-Revised-98 scores from 859 adult patients evaluated by delirium experts (delirium, N=516; nondelirium, N=343). Confirmatory factor analysis found all diagnostic features and core symptoms (cognitive, language, thought process, sleep-wake cycle, motor retardation), except motor agitation, loaded onto factor 1.

Three core domains of delirium validated using exploratory and confirmatory factor analyses.

Objective: To confirm the existence of the proposed three-core symptom domains in delirium by analyzing a dataset of nondemented adults using selected core symptoms as measured by the Delirium Rating Scale-Revised-98 (DRS-R98) scale.

Methods: Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) of proposed delirium core symptoms were conducted in a pooled international dataset of 592 delirious and nondelirious patients using DSM-IV criteria from 14 studies with comparable methodologies. Using DRS-R98 categorization, 445 had either subsyndromal or full delirium and comprised the delirium group.

Phenotype of subsyndromal delirium using pooled multicultural Delirium Rating Scale--Revised-98 data.

Objective: There is no consensus definition for the phenotype of subsyndromal delirium (SSD), a subthreshold state to full delirium. Without an a priori definition we applied advanced analytic techniques to discern SSD.

Method: We pooled Delirium Rating Scale-Revised-98 (DRS-R98) data from 859 DSM-IV diagnosed nondemented delirious adults and nondelirious controls collected by investigators in 7 countries.

[Questionnaire of Diabetes Self-Care Activities: translation, cross-cultural adaptation and evaluation of psychometric properties].

Objectives: To translate into Portuguese, perform cross-cultural adaptation and to evaluate the psychometric properties of the Summary of Diabetes Self-Care Activities Questionnaire - SDSCA.

Materials And Methods: The process followed the international guidelines for the adaptation and evaluation of psychometric properties. The Cronbach's alpha (α) was determined to evaluate the internal consistency (inter-itens correlation) and the reliability (test-retest and inter-evaluator correlation).

Portuguese version of the Delirium Rating Scale-Revised-98: reliability and validity.

Objective: To assess the validity and the reliability of the Portuguese version of the Delirium Rating Scale-Revised-98 (DRS-R-98).

Methods: The scale was translated into Portuguese and back-translated into English. After assessing its face validity, five diagnostic groups (n=64; delirium, depression, dementia, schizophrenia and others) were evaluated by two independent researchers blinded to the diagnosis.

Diagnosis and pharmacological treatment of depressive disorders in a general hospital.

Objective: To determine the point prevalence of depressive disorders in medical inpatients, to identify related sociodemographic and medical factors and to evaluate the psychotropic treatment given.

Method: A cross-sectional study identifying the prevalence of depressive disorders and related factors combined with a prospective longitudinal study evaluating the psychopharmacological treatment were conducted. Medical inpatients, aged 18 years or older, presenting suitability to be interviewed and giving written informed consent were selected.

Validity of the CAGE questionnaire for screening alcohol-dependent inpatients on hospital wards.

Objective: To verify the validity of the CAGE questionnaire in screening inpatients with alcohol dependence.

Methods: In a transversal study, 747 medical inpatients hospitalized on general medical wards in the Federal University of Santa Catarina University Hospital were evaluated. Sociodemographic and clinical data were collected and the following instruments were used: the CAGE questionnaire and the Mini International Neuropsychiatry Interview (MINI), the latter being a semi-structured interview used as the gold standard for diagnosing alcohol dependence (according to DSM-IV criteria).

The validity of the Beck Depression Inventory-Short Form as a screening and diagnostic instrument for moderate and severe depression in medical inpatients.

Objective: To examine the concurrent validity of the Beck Depression Inventory-Short Form (BDI-SF) to detect moderate and severe depressive episodes according to the International Classification of Diseases, 10th edition (ICD-10) criteria in inpatients with heterogeneous medical conditions and to set cut-off scores for its use in medical wards.

Methods: One hundred and fifty-five patients [53% female; mean age (+/- S.D.

The impact of psychiatric comorbidity on length of stay of medical inpatients.

The aim of the study was to determine the impact of psychiatric comorbidity (PC) on length of hospital stay (LOS) of medical inpatients. A prospective cohort study was conducted. A series of 317 medical inpatients consecutively admitted to the general medical wards of a University Hospital composed the sample, after excluding those who refused or who could not be evaluated due to their physical illnesses or treatments (n=78).
