Comparison of delirium detection tools in acute care

Background Delirium is a frequent psychopathological syndrome in geriatric patients. It is sometimes the only symptom of acute illness and bears a high risk for complications. Therefore, feasible assessments are needed for delirium detection. Objective and methods Rapid review of available delirium assessments based on a current Medline search and cross-reference check with a special focus on those implemented in acute care hospital settings. Results A total of 75 delirium detection tools were identified. Many focused on inattention as well as acute onset and/or fluctuating course of cognitive changes as key features for delirium. A range of assessments are based on the confusion assessment method (CAM) that has been adapted for various clinical settings. The need for a collateral history, time resources and staff training are major challenges in delirium assessment. Latest tests address these through a two-step approach, such as the ultrabrief (UB) CAM or by optional assessment of temporal aspects of cognitive changes (4 As test, 4AT). Most delirium screening assessments are validated for patient interviews, some are suitable for monitoring delirium symptoms over time or diagnosing delirium based on collateral history only. Conclusion Besides the CAM the 4AT has become well-established in acute care because of its good psychometric properties and practicability. There are several other instruments extending and improving the possibilities of delirium detection in different clinical settings.

Geriatrische Dermatologie

Zusammenfassung Hintergrund Die Bevölkerung erreicht ein höheres Lebensalter. Begleitend steigt die Inzidenz der Hauterkrankungen. Ziel der Arbeit Dargestellt werden die wichtigsten Hauterkrankungen geriatrischer Patienten. Material und Methoden Es erfolgten sowohl eine Literaturrecherche in der Datenbank von PubMed als auch aus dermatologischen Standardlehrbüchern. Ergebnisse Die Haut geriatrischer Patienten reagiert empfindlicher auf Umwelteinflüsse und kann im Rahmen von internistischen Grunderkrankungen mitbetroffen sein. Aufgrund von verzögerter Diagnostik werden maligne Hauterkrankungen bei alten Patienten erst in höheren Stadien diagnostiziert. Diskussion Physiologische Hautveränderungen im Alter sind durch entsprechende Pflegemaßnahmen zu behandeln. Bei unklaren Hautveränderungen ist eine rasche dermatologische Abklärung anzustreben.
