[Interprofessional multistation practical training in the auditorium : Implementation of the national competence-based catalog of learning objectives for undergraduate medical education in the cross-sectorial area medicine of aging and the aged at the TU Dresden]. / Interprofessionelles Multistationen-Hörsaalpraktikum : Umsetzung des Nationalen Kompetenzbasierten Lernzielkatalogs Medizin im Querschnittsbereich Medizin des Alterns und des alten Menschen an der TU Dresden.

BACKGROUND: The German national competence-based catalogue of learning objectives for undergraduate medical education (NKLM) newly introduced in 2015, provides a variety of learning objectives, competences, as well as practical skills for the cross-sectorial area 7 "Medication of Aging and the Aged" (QB7). Against this background an interdisciplinary teaching concept to mediate all required teaching contents should be developed. OBJECTIVE: Can an interdisciplinary multistation practical course in the auditorium, in which different tasks and skills are trained at each station meet the requirements of the NKLM? MATERIAL AND METHODS: Evaluation by questionnaire and rating of answers on a 6-stage Likert scale. Analysis of the qualitative and quantitative evaluation results of 235 participating students and 13 lecturers in 2016. RESULTS: The interdisciplinary multistation practical course in the auditorium is fully compliant with the NKLM. All theoretical and practical contents and competences could be depicted. The subjective learning effect was assessed by students as good (mean = 2.66; SD = 0.94; N = 230). The available teaching time was rated as being too short in qualitative statements. The lecturers attested a high degree of interest by the students (mean = 2.15; SD = 0.86; N = 13), but criticized that the noise level was too loud. DISCUSSION: Compact, hands-on and interdisciplinary teaching concepts in the QB7 help to make the best use of human and spatial resources and convey all theoretical and practical teaching contents and competences from the NKLM; however, the planning, organization and implementation are very time-consuming.

[OurPuppet - Caring support with an interactive puppet for informal caregivers : Opportunities and challenges in the social and technical developmental process]. / OurPuppet ­ Pflegeunterstützung mit einer interaktiven Puppe für pflegende Angehörige : Chancen und Herausforderungen im sozialen und technischen Entwicklungsprozess.

BACKGROUND: The "OurPuppet" project comprises a sensor-based, interactive puppet that will be developed to communicate with people in need of care during a short period of absence of the informal caregiver. Specially qualified puppet guides will support the use of the new technical development. They instruct people with dementia and caregivers on how to use the puppet and supervise the (informal) care relationship through discussions on a regular basis. OBJECTIVES: The article shows the specific components of users' needs for which the concrete technical development should find answers. It also focuses on the opportunities and challenges for the technical and social developmental process accompanied by these demands. MATERIAL AND METHODS: The analysis of the users' needs is based on a participatory approach. Semi-structured focus group interviews were conducted with informal caregivers, nurses and volunteers in order to identify typical situations in home care settings. The interviews were paraphrased and summarized in order to deduce inductive categories (qualitative data analysis), which describe everyday situations that the technical system should address. RESULTS AND CONCLUSION: Such analyses provide information about the needs of potential users and indicate how to design such technical systems. Furthermore, opportunities and challenges of the development process as well as important contextual information were identified.

Multi-modal signal acquisition using a synchronized wireless body sensor network in geriatric patients.

Wearable home-monitoring devices acquiring various biosignals such as the electrocardiogram, photoplethysmogram, electromyogram, respirational activity and movements have become popular in many fields of research, medical diagnostics and commercial applications. Especially ambulatory settings introduce still unsolved challenges to the development of sensor hardware and smart signal processing approaches. This work gives a detailed insight into a novel wireless body sensor network and addresses critical aspects such as signal quality, synchronicity among multiple devices as well as the system's overall capabilities and limitations in cardiovascular monitoring. An early sign of typical cardiovascular diseases is often shown by disturbed autonomic regulations such as orthostatic intolerance. In that context, blood pressure measurements play an important role to observe abnormalities like hypo- or hypertensions. Non-invasive and unobtrusive blood pressure monitoring still poses a significant challenge, promoting alternative approaches including pulse wave velocity considerations. In the scope of this work, the presented hardware is applied to demonstrate the continuous extraction of multi modal parameters like pulse arrival time within a preliminary clinical study. A Schellong test to diagnose orthostatic hypotension which is typically based on blood pressure cuff measurements has been conducted, serving as an application that might significantly benefit from novel multi-modal measurement principles. It is further shown that the system's synchronicity is as precise as 30 µs and that the integrated analog preprocessing circuits and additional accelerometer data provide significant advantages in ambulatory measurement environments.
