title: [Examination of the opportunity costs and turnover situation in patients with deep sternal infections].
abstract: BACKGROUND
  Each and every hospital of any kind is forced, due to increased cost pressure, to work as economically and as efficiently as possible. This even applies when the operational orientations of the hospitals institutions are different. In the present article an analysis of the repercussions of the treatment of postoperative complications in terms of entrepreneurial practice is given. Our focus is on the opportunity cost.
  
  
  METHODS
  A theoretical calculation of opportunity costs is made based on the example of postoperative infections following cardiac surgery and the resulting treatment. The bases of the examinations are the results collected at the hospital Mediclin Herzentrum Lahr / Baden in 2008. The wound healing disorders were recorded from November 2004 until November 2007 and include 3675 patients who were operated on using a median sternotomy. Out of the 3675 patients 45 (1.2 %) were affected. Various treatment options are at hand. The used therapy algorithm in our practice is dependent on the stage and the development of the infection.
  
  
  RESULTS
  If the high trim point, the medial trim point and the low trim point of the mediastinitis patients, as well as the average revenue and the surcharge omission on exceeding the high trim point (these data can be found in the annual accounts) and knowledge of the actual length of stay of the mediastinitis patient are known, the opportunity cost, respectively potential turnover increases, can be calculated. Reducing the medial trim point from 48.43 to, for example, 36.37 days could potentially produce a turnover increase of as much as 10 633.41 €.
  
  
  CONCLUSIONS
  Keeping patient safety in mind, significant turnover increases can be achieved with adequate planning. The considered sales situation, however, can only be achieved under the same terms: these being free operating room and bed capacities, available personnel, equal cost of materials as well as enough patients. The consideration of opportunity costs could be important for entrepreneurs if staff shortage continues and, in economical terms, non-expendable capacities are created.
