[Cost-effectiveness of a local bone bank based on thermodisinfection according to § 20 b and c AMG and alternatives].

INTRODUCTION: The German tissue law creates a different and more difficult situation for German musculoskeletal tissue banks. The objective aim of the new regulations was an increased safety and a reduction of viral and non-viral disease transmissions. In the authors' case, the government officials demanded a thermodisinfection for human femur heads. As a consequence of the requirements we aimed at an analysis of the cost-effectiveness of an admission according to § 20 b and c "Arzneimittelgesetz" (AMG) and implementation of the "lobator bonebank system™".

METHOD: We calculated the working hour requirements for all medical staff involved in the tissue procedure. Additional costs were the current consumptions of two freezers (cooling power - 80 °C) for one year, the current consumption of one thermodisinfection process, the material cost of one disinfection and documentation set, expenses for laboratory examinations and the non-recurrent expenses for the admission according to § 20 b and c AMG and the "lobator bonebank system". Non-recurrent expenses were calculated for five years according to 610 tissue donations. We compared the overall costs for one processed femur head with the charges of an industrial chemical treating and irradiation.

RESULTS: Expenses for medical doctors were 14.13 € and for nurses 3.71 €. Energy costs were 15.20 € for each stored femur head. Costs for the disinfection and documentation sets were 105.15 €, laboratory expenses were 107.25 €. The non-recurring fee for the admission according to § 20 b and c AMG was 2650 €, the cost for the lobator-sd2 was 12 495 €. The overall expenses for one disinfected femur head were 274.82 € compared to 535.23 € in a tissue service.

CONCLUSION: To comply with legal requirements, operating expenses of the new tissue act increased. Nevertheless we could still prove the cost-effectiveness of a local bone bank in Germany.
