Abstract The purpose of this project is to carry-through a process analysis of processes connected to the flow of the blood samples at the emergency department at Herlev Hospital. This analysis should create a basis for developing suggestions regarding optimization of the mentioned flow and thereby give a solution to reducing the overall turn-over-time of the blood samples. We will focus on processes in the time from a patient arrives at the emergency department to the results of the patient’s blood sample is receivable. This also involves processes at the logistic and biochemical department. The theoretical foundation is based on lean thinking. Focus has been on defining the value aspect in respect to the groups involved and identifying the value chain. Thereby making it possible to eliminate waste and creating a foundation for a better flow. At all times through this project, the lean theory has been used with caution. This is due to leans origin in manufacturing. By using lean tools the valuestream was mapped, which led us to the conclusion, that there are possibilities for improvements. Reducing stocks by rearranging processes and eliminating shifts in responsibility, seems as a necessity for improving the flow. Rearranging processes to cope with the varying stress situation at the emergency department is also seen as an important issue. The level of priority the emergency blood samples is given through the entire system plays a key role in optimizing the flow. Emergency samples should be given the highest level of priority, but it is also important that only real emergency samples should be labeled as such. As part of investigating the current situation, time studies have been completed. Data withdrawn for the computer systems of the department made these studies possible. Not surprisingly the studies revealed a high level of time variation through the entire system. Informal procedures and comments from the personal, had also pointed this out. Reducing the variation through standardization and rearranging of processes is here the last thing emphasized in regard to reducing the turn-over-time of the blood samples. Another objective that is of outmost importance is making sure that the patient’s safety is not compromised. It should be possible to trail the blood samples through the entire system to avoid inexpedient events. All this leaves to a suggested redesigned system which allows the turn-aroundtime to be reduced 43% to 87 ± 37 minutes, while lowering the variation as well as raising the level of traceability.
