Background: ‘Quality in medicine' is a term used in a broad sense. In this work the definition and dimensions of quality in medicine and the implementation of a measurement and reporting system in Germany are discussed. Existing applications are described and possible future effects are pointed out. Methods: The ongoing process of implementing a quality reporting system into the German healthcare system is studied by publicly available legal texts, published reactions of stakeholders and publications of G-BA and IQTIG. Definitions of quality, dimensions of quality and quality measurement in medicine are studied by using textbooks as well as the world wide web and PubMed search. Results: Donabedian‘s ‘dimensions of quality' are fundamental in dealing with quality in medicine. Existing measurement and reporting systems have immanent strengths and weaknesses, as the definition of quality is affected by one‘s point of view. The legislator will have to decide which ‘dimension of quality' is mandatory and how to measure it. Conclusion: Quality has become a control instrument with unforeseeable consequences. A clear definition of the used quality concept is as essential as the use of feasible measurement and reporting systems. The use of routine data could be an interesting option.
Introduction: Adiposity and excessive weight are on the rise in western industrialized countries. In cases where conservative measures fail and surgical interventions are not (yet) desired, gastric balloon therapy has proven to be a safe and reversible endoscopic method. Methods: Aside from weight progression under gastric balloon therapy and by using MRI, our research paper describes the behavior of different abdominal body fat compartments at the beginning and at the end of the gastric balloon therapy. Additionally, the volume of the left liver lobe as well as the fill volume and performance of the gastric balloon were analyzed over the duration of treatment. For assessing potential impacts of weight reduction on the muscle mass, we determined the area of the m. psoas on a comparable cross-sectional area at the beginning and at the end of the therapy. Results: We were able to verify a significant reduction of the layer of subcutaneous fat, adipose capsule of the kidney, and intra-abdominal fatty tissue during the therapy. The volume of the left liver lobe was shrinking in addition to a muscle loss during the balloon therapy. The volume of the gastric balloon remained stable (not hyperinflation). There were variable gas bubbles in the gastric balloon. Conclusion: The gastric balloon is a temporary and successful option for weight reduction by reducing body fat, liver volume, but also muscle mass.
