The aim of this comparative study involving pre- and post-tests was to analyze the effectiveness of patient safety educational materials developed for the Comprehensive Plans for Patient Safety in Korea (2018-2022), and to suggest how to improve patient safety literacy. A face-to-face survey interview comprising items related to general information and patient safety literacy was completed by 217 patients and their families who visited three general hospitals in Seoul and one general hospital in Gyeonggi-do for treatment between 25 October and 15 November 2019. In the interview, the patients were asked questions about whether the patient safety educational materials were "easy to understand," provided "help in safe hospitalization," and enabled patients to practice patient safety independently ("do it yourself"). The literacy of the patient safety educational materials was analyzed using a paired t-test with a p value of 0.05. The comparison between patient safety literacy on pre- and post-tests revealed that among all participants, there were significant differences in "easy to understand," "help in safe hospitalization," and "do it yourself" scores. To improve patient safety literacy, patient education materials need to optimize communication by improving patients' knowledge, skills, and attitudes for maintaining and promoting healthy living.
