A HEALTH ECONOMIC ANALYSIS OF THE USE OF RHBMP-2 IN GUSTILO-ANDERSON GRADE III OPEN TIBIA FRACTURES FOR THE UK, GERMANY, AND FRANCE

Abstract

The introduction of new treatments needs to be both clinically effective and cost effective. Clinicians tend to be unaware of the importance of the latter, and how health economic assessments are undertaken, especially in a public health system where the inclusion of funded treatments is made on a national basis. The purpose of this study was to determine the cost savings from a societal perspective in the use of recombinant human Bone Morphogenetic Protein -2 (rhBMP-2) in grade III A and B open tibia fractures treated with a locked intramedullary nail and soft-tissue management in the UK, Germany, and France. Healthcare system (direct healthcare costs) and costs for productivity losses (indirect health-care costs) were calculated using the raw data from the Bone Morphogenetic Protein Evaluation Group in Surgery for Tibial Trauma “BESTT study”. Return-to-work time for estimation of productivity losses was assumed to correspond with the time of fracture healing. For calculation of secondary interventions costs and productivity losses the respective 2007/08 national tariffs for surgical procedures and average national wages for the UK, Germany, and France were used. From a societal perspective, overall savings per case of €7911 for the UK, €9270 for Germany, and €9291 were calculated. Those savings largely offset the upfront price of rhBMP-2 of €2266(£1,790) in the UK, €2970 in Germany, and €2950 in France. Total net savings can be estimated to be €9.6 million for the UK, €14.5 million for Germany, and €11.4 million for France. For all three countries reduced productivity losses are the key driver for the overall savings. In summary, despite the apparent high direct cost of rhBMP-2 in grade III A and B open tibia fractures, at a national level there are net cost-savings from a societal perspective for all three countries.
