Abstrakt: Aim: The aim of this study was to validate the Delirium Observation Screening Scale (DOSS) in a population of long-term care facility (LTCF) residents in Flanders. Currently there is no validated screening tool for delirium available for the population in this setting in Flanders.
Methods: A multisite, cross-sectional study was conducted in six LTCFs. A total of 338 residents aged 65 years and older were included. Sociodemographic and clinical data, including data from the Montreal Cognitive Assessment (MoCA), Confusion Assessment Method (CAM) and DOSS, were obtained by three trained nurse researchers. For the DOSS, internal consistency was determined, and inter-rater reliability was calculated. To validate the DOSS, the sensitivity, specificity, and positive and negative predictive value of the DOSS relative to the CAM were determined through receiver operating characteristic analysis. This article adheres to the Strengthening the Reporting of Observational Studies (STROBE) checklist for observational research.
Results: For 338 residents, delirium assessments were completed during an early or late shift. The prevalence of delirium was 14.2% as measured with the DOSS. The reliability (α) for the CAM and DOSS was assessed, as was the inter-rater reliability (κ) and the area under the curve. The sensitivity and specificity for a cut-off value of 3 on the DOSS by Youden's index were very high, as was the negative predictive value. The positive predictive value was good.
Conclusions: This study showed that the DOSS is a reliable and valid instrument to screen for delirium in LTCF residents in Flanders. Geriatr Gerontol Int 2024; 24: 619-625.
