Infusion pumps are one of the most frequently used medical instruments in hospitals. Newer devices are equipped with the History Function. This function keeps the logs of device movements such as alarms and key operations on the device. This study is to investigate the correct usage of the device by utilizing this function. The usages investigated are power-on procedure, and procedures at occlusion alarms and bubble detection alarms.
As a result, wrong sequences of usage at the power-on procedure and the procedure at occlusion alarms became clear. In addition, more than half of the devices recorded the occlusion alarms and the bubble detection alarms, during usage for a single patient. We notified to nurses these findings and the right procedure of the device. After notification, we repeated the similar evaluation. The procedure at the occlusion alarms was improved remarkably. However, there was no change about the frequency of alarm appearance.
The History Function is useful when we study the usage of the device in the clinical settings. This study indicates that the information about error occurrences and the right procedure to nurses can improve the usage of the infusion pumps effectively.
