New approach for the time motion analysis of medical staffs in a ward by video image processing

Time motion analysis is a popular tool for the job analysis of the medical staffs in a ward, especially for nurses. The usual time motion analysis is thought to be expensive and exhaustive for the study being conducted by trained observers continuously. Recently the more simple method is proposed applying the RFID, however, the study cost is also expensive and remains the ambiguity for the job detail analysis. In this study, we proposed a new approach for the time motion analysis applying the video image processing technique with difference imaging. The method can estimate the busyness of the staffs that operate in the room. And this new system requires no particular or expensive video system and computer system. For the verification on this method, we conducted verification experiment in the laboratory room. As the first step, in this research, the verification experiment was conducted at the outside of clinical site. And found its availability relating to the job analysis.
