OBJECTIVES: Contrast agents for computer tomography (CT) are presented in glass or plastic vials or syringes. Those containers take a lot of volume and are of considerable weight resulting in important costs for storage and waste processing. There is also a risk for injuries with sharp lips and spilling due to breakage. Those containers need the use of small medical devices to allow injection of contrast agents. The ScanBag® container was developed to overcome these problems. The objectives of this study were to assess the impact on the hospital budget of using Scanbag® instead of other containers. METHODS: According to the Ispor recommendations for budget impact models (BIMs), we developed a BIM to demonstrate the economical advantage of using contrast agents in ScanBag® from a hospital perspective. Resource use in terms of broken products, injuries, storage, waste management, small medical devices, and mono- or multipatient use for each presentation type were collected via literature and expert interviews in public and private radiology centers in France, Belgium, Germany, Italy, Spain and the United Kingdom. RESULTS: Replacing 1000 glass vials of 200 ml iobitridol by the same volume in ScanBag® reduces broken products and injuries by 100%, storage space by 43.8% and waste weight by 89.4%. Total cost savings for this simulation range from €7076 in Germany to €8484 in Italy when costs of broken products, injuries, storage, waste management and small medical devices are considered.  Depending on the injector used, cost savings of up to €6,700 can be obtained for small medical devices. CONCLUSIONS: Only in changing glass vials to ScanBag®, costs for hospitals can be reduced through savings in broken products, injuries, storage and waste management. Largest cost savings are made on small medical devices.
