Abstract
To avoid medical accidents, it is needed to handle with two approaches: Systems Approach and Person Approach(Reason, 2000). Systems Approach is an organizational effort and has already been practiced in many hospitals. On the other hand Person Approach is on individual problems such as the need of safety consciousness. This research is about the Person Approach. Under present circum-stances incident reports are not fully used in hospitals. It is the point this research focuses on, and analyses have been made in relationship between the incident reports and the attitude survey as the Person Approach. Investigations were conducted in two hospitals so far and the analyses have been made on relationship between the occurrence rate of incidents and safety attitude based on individual personalities. We classified them into a high-risk(H) group and a low-risk(L) group based on the number of medical errors caused. As a result, significant difference is recognized in clinical manuals understanding and personality test(Egogram and POMS) in two groups of those who are the so-called “repeaters” and those who are not. As for the results of relations between personality test and the two groups, the value of AC and T-A was higher in the H group than in the L group.
