This study, is a result of a collaboration between Uddevalla hospital, Västra Götalandsregionen, and Chalmers University of Technology. The purpose of the study is to designing a new materials supply process of surgical material for the operation clinic at Uddevalla hospital which enables for decreased changeover time between surgeries. The study is conducted at Uddevalla hospital, a hospital which provides elective patient care. The flow of surgical material towards the part of the operation clinic that performs hip surgery is investigated. In order to map out the flow of surgical material towards the operation clinic, the project team follows the material from contamination during surgery, to it being back in the operation clinic storage, sterilised and packed. Data is collected through literature search, and a combination of structured observations and semi-structured interviews at Uddevalla hospital, NÄL hospital, and Mölndal hospital. During the data collection and the description of the current situation at Uddevalla hospital, it is made clear that material handling activities take place at the operation clinic which could be performed elsewhere by other personnel. Further, handling of separate disposable articles is identified as time consuming, and the operation table setting is appointed as the activity that effect the changeover time the most. A new materials supply process is suggested in which the activities operation cart packing and disinfection are externalised from the changeover process at the operation clinic to the central sterilisation department. Further, the project team recommends the introduction of operation table setting rooms. The project team also suggests the introduction of procedure packs, which are packages in which all disposable material needed for a type of surgery are combined in a single package. The new materials supply process, through externalisation of material handling activities, freesup time for the operation clinic personnel, and enables for more patient care, hence reduced changeover time between surgeries. The operation table setting rooms allow the operation table setting to be performed during ongoing surgery. The procedure packs simplify the cart packing by reducing the number of articles to collect, and they speed-up the operation table setting since fewer packages have to be opened. The externalisation of the disinfection process and the operation cart packing require a new ITsystem in which orders can be placed and information sharing between the central sterilisation department and the operation clinic is enabled. To further improve the communication between the two units, it would be beneficial if they could be located on the same floor, which requires a new operation building.
