医療安全対策の有効性を視覚化する─稀な事象に対する評価方法の提案─

抄録

For events with a low occurrence rate, such as medical incidents, we were able to determine the evaluation before and after taking medical safety measures by statistical methods (testing for differences in population rate). The point of this method is that we evaluated the occurrence rate of incidents to the total number of examinations (number of incident occurrence real number plus number of examinations carried out without any problems). Our results suggest that this technique becomes the evaluation technique as the effective method of medical safety measures. The present studies demonstrated that the evaluation technique by the testing for differences in population rate become the indicator to judge the effectiveness of the medical safety measures in the following cases. (1) When we evaluate the decrease in incident for the long term before and after safety measures. (2) When we evaluate the effectiveness of measures in the middle evaluation after safety measures.
