Burden of Illness Imposed by Severe Sepsis in Germany

Sepsis is a systemic response to severe infection in critically ill patients and is among the most frequent causes of death in intensive care medicine. Every year between 44,000 and 95,000 persons suffer from this illness in Germany. With the help of a retrospective electronic chart analysis in three adult ICUs of three university hospitals we calculated by a bottom-up approach the direct costs of these patients yielding per patient costs of 23,297 euros on average. Linking the direct costs per patient with the incidence data, the total direct costs for severe sepsis in Germany per year were estimated to range from 1,025 to 2,214 million euros. Direct costs, however, were found to make up only about 28% of the burden of disease of severe sepsis. The indirect costs range between 2,622 and 5,660 million euros. Productivity loss due to premature death does account for the largest part of the indirect costs. In conclusion, severe sepsis imposes annual costs between 3,647 and 7,874 million euros to the German society.
