Cost-Benefit Analysis of Mis Tha: Model-Based Analysis of the Consequences for Switzerland

Abstract

The objective of this study was to show model-based economic consequences of minimal invasive surgery total hip arthroplasty (MIS THA). The model is based on hospital and rehabilitation costs and lowering of loss of productivity. This study used conventional THA data from Switzerland and cost-effectiveness MIS THA analysis from the United States. According to our model, a total of € 42.1 – 70.1 million can be saved annually in Switzerland when using MIS THA instead of conventional THA. Annual savings of € 7,8 – 12,9 million result from the significantly shorter hospital stay. The savings potential for rehabilitation costs is € 10,5 – 17,5 million annually. In addition, the productivity loss for the economy is lowered by € 23.8 – 39.7 million annually. According to this economic study we recommend the introduction of MIS techniques in THA. MIS THA surgical techniques may allow the reduction of healthcare costs. Despite the promising economic advantages of MIS THA, clinical studies are necessary to prove long-term benefits.
