Non-contact monitoring of agitation and use of a sheltering device in patients with dementia in emergency departments: a feasibility study

Background Agitation is common in geriatric patients with cognitive impairment, e.g. in persons with dementia (PWD), who are admitted to an emergency department (ED). It might be a first sign of upcoming delirium and is associated with a higher risk of an unfavorable clinical course. Hence, monitoring of vital signs and enhanced movement as indicators of upcoming agitation is essential in these patients during their stay in the ED. Since PWD rarely tolerate fixed monitoring devices, a novel developed non-contact monitoring system (NCMSys) might represent an appropriate alternative. Aim of this feasibility study was to test the validity of a NCMSys and of the tent-like “Charité Dome” (ChD), aimed to shelter PWD from the busy ED environment. Furthermore, effects of the ChD on wellbeing and agitation of PWD were investigated. Methods Both devices were attached to patient’s bed. Tests on technical validity and safety issues of NCMSys and ChD were performed at the iDoc institute with six healthy volunteers. A feasibility study evaluating the reliability of the NCMSys with and without the ChD was performed in the real-life setting of an ED and on a geriatric-gerontopsychiatric ward. 19 patients were included, ten males and nine females; mean age: 77.4 (55–93) years of which 14 were PWD. PWD inclusion criteria were age ≥ 55 years, a dementia diagnosis and a written consent (by patients or by a custodian). Exclusion criteria were acute life-threatening situations and a missing consent. Results Measurements of heart rate, changes in movement and sound emissions by the NCMSys were valid, whereas patient movements affected respiratory rate measurements. The ChD did not impact patients’ vital signs or movements in our study setting. However, 53% of the PWD (7/13) and most of the patients without dementia (4/5) benefited from its use regarding their agitation and overall wellbeing. Conclusions The results of this feasibility study encourage a future controlled clinical trial in geriatric ED patients, including PWD, to further evaluate if our concept of non-contact measurement of vital signs and movement combined with the “Charité Dome” helps to prevent upcoming agitation in this vulnerable patient group in the ED.

Agent-Based Information Management

Abstract: Clinical care is characterized by the distribution of data among personnel, locations, and various types of media. Clinical information systems (CIS) should provide help in collecting, preparing and presenting data. The dispersal of information emerges as a problem in clinical information systems especially when decisions have to be made with emergency patients. The primary goal of the research project AGIL (agent based information logistics) * is to develop a multi- agent system that supports the clinical information flow. The secondary goal is to explore and generalize an agile development methodology for such multi-agent systems. A tool for the modeling of processes and the development of the software is developed

Zum Einsatz von Informationstechnologie zur Verbesserung der Arzneimitteltherapiesicherheit (Memorandum AMTS-IT)

[english] Information technology in health care has a clear potential to improve quality and efficiency of health care, especially in the area of medication processes. On the other side, existing studies show possible adverse effects on patient safety when IT for medication-related processes is developed, introduced or used inappropriately. The objective of this paper is to summarize definitions and observations on IT usage in pharmacotherapy, and to derive recommendations and future research priorities for decision makers and domain experts. The recommendations address, among others, a stepwise and comprehensive strategy for IT usage in medication processes, the integration of contextual information for alert generation, the involvement of patients, the semantic integration of information resources, usability and adaptability of IT solutions and the need for their continuous evaluation
