A Tunable Strain Sensor Using Nanogranular Metals

This paper introduces a new methodology for the fabrication of strain-sensor elements for MEMS and NEMS applications based on the tunneling effect in nano-granular metals. The strain-sensor elements are prepared by the maskless lithography technique of focused electron-beam-induced deposition (FEBID) employing the precursor trimethylmethylcyclopentadienyl platinum [MeCpPt(Me)3]. We use a cantilever-based deflection technique to determine the sensitivity (gauge factor) of the sensor element. We find that its sensitivity depends on the electrical conductivity and can be continuously tuned, either by the thickness of the deposit or by electron-beam irradiation leading to a distinct maximum in the sensitivity. This maximum finds a theoretical rationale in recent advances in the understanding of electronic charge transport in nano-granular metals

Hilft das zahnmedizinische Bonussystem den stationär Pflegebedürftigen?

Oral health of long-term care (LTC) residents is often poor. From 30 random German LTC facilities, 242 random residents (Berlin n=75, Northrhine-Westfalia (NRW) n=94, Saxony n=73) (median age: 82 years, female: 78.5%) were interviewed as to their use of dental services, possession of a bonus booklet (BB), and completeness of records. Only 18.6% possessed a BB. Significant regional differences were observed (Berlin=5.3%, NRW=18.1%, Saxony=32.9%) (χ(2) test p<0.01). The number of teeth was higher (Mann-Whitney test p=0.01) and the time since last dental visit shorter (p<0.01) for all residents with a BB. Only 18.6% of people possessing a BB declared not having had a dental appointment within the previous 12 months (LTC residents without BB 51.3%). As a means towards improved quality management in nursing, better oral infection control of residents and increased oral health and general quality of life, the introduction of a regular annual preventive dental screening program including the use of a dental bonus system are suggested

Methods of Health Economic Evaluation for Health Services Research

Icks A, Chernyak N, Bestehorn K, et al. Methoden der gesundheitsökonomischen Evaluation in der Versorgungsforschung. Das Gesundheitswesen. 2010;72(12):917-933.On August 30, 2010, the German Network for Health Services Research [Deutsches Netzwerk Versorgungsforschung e.V. (DNVF e.V.)] approved the Memorandum III "Methods for Health Services Research", supported by the member societies mentioned as authors and published in this Journal [Gesundheitswesen 2010; 72: 739-748]. The present paper focuses on methodological issues of economic evaluation of health care technologies. It complements the Memorandum III "Methods for Health Services Research", part 2. First, general methodological principles of the economic evaluations of health care technologies are outlined. In order to adequately reflect costs and outcomes of health care interventions in the routine health care, data from different sources are required (e.g., comparative efficacy or effectiveness studies, registers, administrative data, etc.). Therefore, various data sources, which might be used for economic evaluations, are presented, and their strengths and limitations are stated. Finally, the need for methodological advancement with regard to data collection and analysis and issues pertaining to communication and dissemination of results of health economic evaluations are discussed.Das Deutsche Netzwerk Versorgungsforschung e. V. (DNVF e. V.) hat am 30.08.2010 getragen von den genannten im DNVF organisierten Fachgesellschaften und Organisationen, das Memorandum III „Methoden für die Versorgungsforschung” Teil 2 verabschiedet, das in dieser Zeitschrift publiziert wurde [Gesundheitswesen 2010; 72: 739-748]. Die vorliegende Publikation fokussiert auf die Methodik der ökonomischen Evaluation der Gesundheitstechnologien bzw. Interventionen und stellt eine Vertiefung zu dem Memorandum III „Methoden für die Versorgungsforschung” Teil 2 dar. Zunächst werden allgemeine methodische Standards gesundheitsökonomischer Evaluationen, d. h. Studien, die die Kosten-Nutzen Relation (Wirtschaftlichkeit) von Interventionen untersuchen, kurz dargestellt. Um Versorgungsrealität adäquat zu reflektieren, müssen zur Ermittlung der Interventionskosten und -effekte oft mehrere Datenquellen, z. B. Wirksamkeitsstudien, Register, administrative Quellen usw., verwendet werden. Daher werden für die gesundheitsökonomischen Evaluationen im Rahmen der Versorgungsforschung potenziell geeignete Datenquellen vorgestellt, ihre Vorteile und Limitationen genannt. Anschließend wird der Weiterentwicklungsbedarf der Methodik im Hinblick auf die Datenerhebung, und -auswertung sowie die Kommunikation und Dissemination der Ergebnisse diskutiert
