We report about the 2-year results of a physician-based active cost management model for oncological therapies in a German OB/GYN university clinic. Over 2 years more than 4,000 oncological cycles were prospectively and individually analyzed regarding costs and reimbursement mode. Main aim was reducing costs without lowering cycle number and standard of care. Within two years pharmaceutical costs were reduced by 83.4% or 785,976-EUR. All causes for a previous financial loss were identified and eliminated. Debts were paid back and employment of new staff and investments were possible. With this first active cost management model by and for physicians, oncological therapies can be performed cost covering even in a university clinic. Although developed for optimization of cost coverage of oncological therapies in Germany, this model is universally transferable.
