Abstract
Interviews with persons involved in medical incidents based on incident reports (IRs) are an important safety management activity. This study examined the influence of the quality of IRs information on the content of questions asked during interviews. High quality IR was defined as containing a large amount of incident information and written in a way that is easily understood by the investigator. Eleven participants with incident investigation experience and 15 with no experience were presented with three fictitious IRs with different quality of information and asked to list the questions. They were compared and the tendency of the questions in each IR was clarified. The results showed that low quality IRs had more questions based on speculation about the event, while high quality IRs had more questions about incident factors based on IRs. In low quality IRs, participants with no experience in incident investigation were asked more peoplefocused questions than those with experience. Inherently, questions that focus on man, machine, media, management, etc. are important, but this study revealed the detrimental effect of fewer such questions when IRs’ quality was low.
