The purpose of this project was to promote the satisfaction of the patients and families in the explanation by doctors on invasive interventions. Formerly the doctors in our Intensive Care Unit (ICU) explained the invasive procedures to patients and families orally, however the explanations were always incomplete due to their heavy workload. The results of questionnaires revealed lack of teaching aid, insufficient time for discussion, easily disturbed environment and no time to ask questions as the major reasons for dissatisfaction. We provided teaching materials, posters, videos and an isolated space in this project. With this design, the satisfaction rate was increased from 43.1 % to 92%. The goal achieved rate was 132.5%, with the rate of improvement being 113.5%. Finally we included this design in our standard book to provide high quality medical services.
