The purpose of this project was to increase the thoroughness of nursing instruction during pre-examinations in the Urological Department. Observation of nurses checking admitted patients during the examination showed that the nursing instruction performance rate was 64% and the thoroughness rate was 56%. By analyzing the lack of thoroughness, the reasons were as follows: 1. Uncertainty about the schedule, without enough preparation before the examination. 2. Lack of nursing instruction notes for examinations. 3. Insufficiency professional knowledge. From March to December 2004, we started this improvement project by giving nursing instruction earlier, and continuously monitoring the nursing instruction performance rate to increase the thoroughness of nursing instruction. After the improvement of this project, the performance rate was raised to 94% and the thoroughness rate was raised to 98%. The satisfaction rate of patients was raised from 89% to 100%. To conclude, this project is worth distributing system-wide.
