Abstract: Objective: To develop a discharge preparation service program for patients after Percutaneous Coronary Intervention (PCI) and evaluate its clinical effects, so as to provide a reference for improving post-discharge nursing quality. Methods: Through literature analysis and team discussion, a discharge preparation service program for patients after PCI was developed based on the Transition Theory. A total of 60 Acute Myocardial Infarction (AMI) patients after PCI admitted to the cardiology ward of a tertiary general hospital in Shanghai from January to August 2023 were conveniently selected and were divided into a control group (n=30) and an intervention group (n=30) according to the hospitalization dates. The control group received routine post-PCI management for AMI, while the intervention group received the discharge preparation service program. Results: The program comprised four phases: post-admission, during hospitalization, pre-discharge, and post-discharge, with 31 specific items. The intervention group demonstrated significantly higher scores in the discharge readiness scale (155.07±10.83) and discharge guidance quality scale (187.26±10.47) compared to the control group (141.13±10.42 and 170.12±9.59 respectively; P<0.05), and the team's theoretical knowledge and practical competencies were improved (both P<0.05). Conclusion: The developed discharge preparation service program can effectively improve the discharge readiness and the quality of discharge guidance for AMI patients after PCI, and enhances the professional capability of the team.
