Delirium Screening: A Systematic Review of Delirium Screening Tools in Hospitalized Patients

Abstract

The Confusion Assessment Method was the most widely used instrument to identify delirium, however, specific training is required to ensure optimum performance. The Delirium Rating Scale and its revised version performed best in the psychogeriatric population but requires an operator with psychiatric training. The Nurses' Delirium Screening Checklist appears best suited to the surgical and recovery room setting. The Single Question in Delirium shows promise in oncology patients. The Memorial Delirium Assessment Scale, while demonstrating good measures of validity in the surgical and palliative care setting, may be better used a measure of delirium severity. The 4As Test performed well when delirium was superimposed on dementia, but it requires further study.

Evaluation of delirium screening tools in geriatric medical inpatients: a diagnostic test accuracy study

“…An ideal screening tool for delirium should be brief, require little or no training, and be appropriate to the clinical setting it is used in. It should prioritise high sensitivity over specificity, reliably detecting those with delirium and also have acceptable specificity, accurately identifying those without delirium as screen negative [6].…”

Early Delirium Assessment for Hospitalized Older People in Indonesia: A Systematic Review

“…Even CAM is already assessed in so many times, the sensitivity and specificity remain in a good shape (De & Wand, 2015). Currently, one study reported that the sensitivity of CAM ranges from 40-100%, while the specificity ranges from 63-100%.…”

“…Nurse Media Journal of Nursing, 6 (1), 2016, When it comes to assessing delirium in older people, CAM only takes several minutes, when compared to other questionnaire (De & Wand, 2015). CAM is also available in some modified forms, which can be set up for different needs/settings.…”

Propriedades Psicométricas De Instrumentos De Medidas: Bases Conceituais E Métodos De Avaliação - Parte I

“…6,8 The adaptationof instruments for the evaluation of subjective constructs,for different languages and cultures, has also been the subject of a large number of investigations, including discussions on the appropriate methodological process to ensure that the instrument preserves its properties of validity and reliability after adaptation. 1 In the last decade, this type of research has produced a considerable number of nursing researches, [9][10][11][12][13] reflecting the concern of these professionals to identify the most appropriate measurement instrument for a given situation or condition, considering the one that addresses the monitoring of patients in clinical practice and that contemplates the perception of the individuals themselves in the evaluation of their state of health. 14 From the analysis of the increase in measurement instruments available in the scientific literature, the authors identified two important aspects to be overcome: the need to identify the available questionnaires for a specific use in the various subjects, so that they may be known to interested professionals and the need to know the measures that would be considered more appropriate (valid and reliable) among the various available instruments.…”
