    Description / Table of Contents: Summary Due to legal regulations, external quality assurance is mandatory in Germany. Supported by the German Health Ministry (BMG),we present the results of a multicenter study in four hospitals with different structures on 1042 inpatients with the trace diagnosis of schizophrenia (ICD 10). We defined disease-specific indicators of structure, process, and outcome quality, developed an assessment instrument, and implemented a feedback system for quality comparison. The resulting quality profiles are useful as a starting point for internal quality management.
    Notes: Zusammenfassung In einem vom BMG geförderten 2-jährigen Projekt wurde anhand von insgesamt 1042 Behandlungsfällen an 4 psychiatrischen Kliniken unterschiedlicher Struktur in Nordrhein-Westfalen die Voraussetzung für eine externe Qualitätssicherung mit Hilfe der Tracer-Diagnose Schizophrenie geschaffen und durchgeführt. Ziele waren die Evaluation eines Erhebungsinstrumentariums, die Entwicklung von Qualitätsindikatoren und der Aufbau eines Rückmeldesystems zur Optimierung des internen Qualitätsmanagements. Anhand der erhobenen Daten ist es auf wissenschaftlich-statistischer Basis gelungen, Qualitätsindikatoren und eine vergleichende Art der Rückmeldung zu entwickeln, die neben Ergebnisvariablen auch Struktur-, Patienten- und Prozessvariablen beinhaltet. Diese Qualitätsprofile bilden einen wesentlichen Ausgangspunkt für krankheitsspezifische Problemanalysen im Rahmen eines internen Qualitätsmanagements.

    Notes: Abstract We study exact self-duality in the model of a Brownian particle in a washboard (WB) potential which describes a Josephson junction (JJ) coupled to an environment, for arbitrary temperature and arbitrary form of the spectral density of the environment. To this end we introduce the quantum dissipative Villain model (QDVM), which models tunneling of a degree of freedom coupled to a linear quantum environment through an infinite set of states. We derive general exact mappings on various dual discrete representations (one-dimensional Coulomb gases or surface-roughening models) which are exactly self-dual. Then we show how the QDVM maps exactly onto the WB model and use duality relations to calculate the leading terms of the total impedance of a JJ circuit, for general frequency dependence of the spectral density of the environment and arbitrary temperature.
