BACKGROUND: Consequences of the volume outcome relationship are controversial. Objectification based on data analysis is strongly needed. The aim of this publication was to analyse the effects of volume outcome reallocations based on German inpatient data. METHOD: The analysis based on inpatient data of the Krankenhauszweckverband Koeln, Bonn und Region (Hospital Association of the Cologne and Bonn Region) of 2002 and 2005. Relevant data sets were identified according to the effects of current German regulations on volume outcome on the special fields liver transplant, kidney transplant, complex pancreatic surgery, and complex oesophageal surgery. RESULTS: The effects of current German regulations on volume outcome results differed greatly between the four surgical specialities. There were fewer effects on kidney transplant, but due to an already very high level of centralisation 34% (oesophagus) and 8% (pancreas) of the hospitals stopped related surgery. This affected 8.9% (oesophagus) and 2.2% (pancreas) of related cases. CONCLUSION: Concentration and the formation of specialised medical centres are results of the implementation of volume outcome relationships. The quality of medical treatment does not automatically improve from this development. It is necessary to analyse any correlation between quality and frequency of treatment or other criteria such as know-how, structure and process management, and multidisciplinarity.     

How enthusiastically should the use of monounsaturated fats be encouraged?

The Garg study diet supplied 50% of the calories from fat (33% from monounsaturated fat), which eliminates much of the bulk from the diet. Substituting monounsaturates for carbohydrates in the diet translates into giving up 120 calories from a carbohydrate source (very large potato, 1 1/2 slices of bread, 1 cup of cereal, etc) for a tablespoon of olive oil. Somehow that doesn't seem like a good exchange. Abbott et al substituted complex carbohydrates for saturated fat in the diet and accomplished the same result as Coulston et al with a low-carbohydrate (40%), moderate-fat (40%) diet. The American Diabetes Association suggested that if diabetes was poorly controlled and hypertriglyceridemia a problem, monounsaturates might be useful to maintain caloric balance. However, in light of the high incidence of obesity in persons with NIDDM and recent studies on the ease of dietary fat storage in adipose tissue, should fat of any kind, including monounsaturated fats, be substituted for carbohydrates in the diet of persons with diabetes?

Within the scope of the symposium “Rescue Medicine in Germany” (held at the Reisensburg near Ulm in 2002), the need for a standardized data acquisition set for prehospital cardiac arrest patients was identified. Therefore, the working group “Emergency Medicine” of the German Society of Anesthesiology and Intensive Care Medicine (DGAI) created a nationwide data acquisition system for primary medical care in prehospital cardiac arrest patients treated with cardiopulmonary resuscitation procedures. The system is in full accordance with the “Utstein style.” Integration of this data acquisition system, for example into the “Dortmund protocol,” is providing a standardized data web base of all acquired prehospital data analyze and to compare processing and structural quality. As additional modules for this nationwide data web base system, an inhospital module “further clinical treatment” and a “long-term follow-up” module are currently in the developmental process.
