Outline of Final Research Achievements

It is important to design a methodology that considers operational complexity especially that associated with invasive procedures. The purpose of this study was to develop a method that provides the means to effectively and efficiently comprehend a situation when problem occur in hospitals. In order to elucidate the structure of this complex process, we identified a healthcare operation process as a process flow consisting of unit processes and described the process flow and elements of each unit process. This approach allows us to reveal the vulnerability of the process when complications occur. Lastly, we apply the method to actual cases during the insertion of a central vein catheter (CVC), a highly invasive intervention, at hospital A to illustrate its effectiveness.
