The possibility of outpatient implantation of defibrillators, devices for cardiac resynchronization, and event recorders (collectively called cardiac implantable electronic devices, CIEDs) is becoming increasingly important. In Germany, only a few options for outpatient implantation are currently realized. Furthermore, there is a lack of uniform, recognized, and binding quality criteria. This article provides insight into the current contract constellations for outpatient surgery and defines a first, holistic quality concept for outpatient implantations of CIEDs. The present works aims to initiate a discourse in the specialist society in order to define a coordinated, binding quality concept. Then, this should serve as the basis for future outpatient implantation services, enabling comparability and to contribute long-term evidence.

Objective: The aim of this study was to define body fat percentiles for German children and adolescents aged 3-16 years using the largest German database., Methods: The study population included 11,632 girls and 11,604 boys. Data were pooled from: i) Kiel Obesity Prevention Study (KOPS), acquisition period: 1996-2008, n = 12,237; ii) 'Better diet. More exercise. KINDERLEICHT-REGIONS', acquisition period: 2007, n = 9,405; and iii) examination of Jena schoolchildren, acquisition period: 2005, n = 1,594. Body fat mass was measured by bioelectrical impedance analysis using a population-specific algorithm. Data were weighted to achieve a representative sample for Germany. Percentile curves were constructed by the LMS method and proved by Worm plots and Q-statistic., Results: In both genders, the higher body fat percentile curves sloped downwards to age 7 years, whereas the lower percentiles declined up to 8.5 years. Thereafter fat mass remained nearly constant with age in boys and increased in girls. The 10th percentile achieved a minimum of 10-11% body fat in both genders, whereas the 90th percentile curve fluctuated between 29 and 44% in boys or 30-43% in girls. The association between fat mass and blood pressure was too weak to define disease-related cut-offs., Conclusion: These body fat percentiles are suitable reference values for German children and adolescents., (Copyright © 2012 S.
