Abstract: Objective To investigate the application effect of multidisciplinary discharge instruction for patients after cardiac surgery. Methods A total of 81 patients who were admitted to Zhuhai People's Hospital and underwent cardiac surgery from April, 2021 to September, 2022 were selected as subjects by the convenience sampling method, and they were divided into control group with 40 patients and intervention group with 41 patients using a random number table. The patients in the control group received routine discharge instruction, and those in the intervention group received multidisciplinary discharge instruction. At discharge, Readiness for Hospital Discharge Scale (RHDS), Quality of Discharge Teaching Scale (QDTS), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS) were used to assess the readiness for discharge, the quality of discharge instruction, and the psychological state of patients, and the two groups were compared in terms of unscheduled readmission rate at 1 and 3 months after discharge. Results Compared with the control group, the intervention group had significantly higher RHDS and QDTS scores and significantly lower SAS and SDS scores (P<0.05). There was no significant difference in unplanned readmission rate between the intervention group and the control group at 1 and 3 months after discharge (P>0.05). Conclusion Multidisciplinary discharge instruction for patients after cardiac surgery can improve the quality of discharge instruction, increase the readiness for hospital discharge, and alleviate the anxiety and depression mood of patients at discharge.
