Abstract: Objective: To develop and evaluate an education platform for cardiology inpatients, providing decision-making support for clinical nurses' inpatient education work. Methods: The mission of health education for cardiology inpatients and the list of functions of the health education platform were determined by reviewing medical records, conducting literature searches, organizing expert demonstration meetings, etc. The platform was then developed and implemented in clinical practice. Using convenience sampling, 600 patients admitted to two wards of the cardiovascular department of a tertiary grade A hospital and 80 nurses were recruited in Wuhan from October to November 2024. The two wards were divided into the control group and the intervention group by a random number table. Patients in the control group received education using traditional methods, while those in the intervention group received education using an information-based education platform. The two groups were compared in terms of the omission rate of educational items, patient satisfaction with nursing care, and clinical nurses' self-efficacy. Results: The information-based education platform included 9 categories with a total of 153 items of inpatient education content. After the intervention, there were 11 cases (3.7%) of omission in the intervention group - course diagnosis and treatment education, while there were 65 cases (21.7%) of omission in the control group. The patient satisfaction score with nursing care was 21.81±3.49 in the intervention group and 20.23±2.57 points in the control group. The self-efficacy score of nurses in the intervention group was 34.33±3.16, while that in the control group was 23.48±7.29. All these differences were statistically significant (all P<0.05). Conclusion: The information-based education platform for hospitalized patients in the cardiology department is scientifically practical and provides reliable decision support for optimizing patient education.
