Emergency departments are hospital units for patients, who need emergency and acute care. Due to the state of patients, shift leader nurses and physicians need to do important decisions concerning patients’ treatment and care, quickly and efficiently. To be able to do that, they have to get needed information easily and efficiently. That is called knowledge-based leadership. When knowledge-based leadership is successful, the organisations’ information and knowledge are processed in a way, that they may be exploited in a best possible way. Unfortunately, nowadays the situation is not ideal in emergency departments, even though a lot of money has been invested in new information systems. Staff dissatisfaction with existing information systems have been reported and can be seen on staff satisfaction. On the other hand, there is not much research on how the information systems impact on shift leader nurses’ and physicians’ work. A quasi-experimental study was done in the years 2015 – 2016 in emergency departments in three central hospitals in Finland exploring the movement patterns of the shift leader professionals before and after implementation of a new information system in on unit, called intervention unit. Data was collected with Bluetooth beacons installed in different hospital rooms and corridors and with smartphones carried by shift leader nurses and physicians. Improving the knowledge management of leaders with new information systems, it is expected, that it decreases the effort needed to seek information to support decision-making. However, the result was not so unambiguous. The movement patterns changed, but they changed also in control units. A new information system can influence on hospital leader shift personnel mobility. Unfortunately, the lack of data made it impossible to count and compare actual walked distances. There should be more data – that is – from every day, every shift and every shift leader professional around the clock. Only that way, the comparison would be reliable. The mobility data from hospitals was already collected, when this thesis was written, so collecting the data was not part of this thesis.
