[Effect of Kiken-Yochi training (KYT) induction on patient safety at the department of radiological technology]. 
In this report, we evaluated whether radiological technologists' (RTs') awareness of patient safety would improve and what kind of effects would be seen at the department of radiological technology by introducing KYT [K: kiken (hazard), Y: yochi (prediction), T: (training)].  KYT was carried out by ten RTs based on a KYT sheet for the department of radiological technology.  To evaluate the effects of KYT, we asked nine questions each to ten participants before and after KYT enforcement with regard to their attitude to patient safety and to operating procedures for working safely.  Significant improvements after KYT enforcement were obtained in two items concerning medical safety: It is important for any risk to be considered by more than one person; The interest in preventive measures against medical accident degree conducted now) and one concerning operating procedures (It is necessary to have a nurse assist during testing with the mobile X-ray apparatus) (p<0.05).  Performing KYT resulted in improved awareness of the importance of patient safety.  KYT also enabled medical staffers to evaluate objectively whether the medical safety measures currently performed would be effective for patients.
