One of the most common procedures performed worldwide is for herniated discs. The discharge plan for a patient having lumbar disc herniation (LDH) surgery expedites recovery, guarantees the efficacy of therapy, enhances self-care routines, and successfully prevents recurrence. Aim of the study: Was to evaluate the effect of implementing discharge plan regarding patients self-care practice undergoing herniated lumbar disc surgery. Subjects and Methods: Research design: A quasi experimental research design was used. Setting: The study was carried out in the outpatient clinic and the neurosurgery department at New Surgery Hospital at Zagazig University Hospital. Subjects: From the aforementioned context, sixty adult patients were chosen as a purposeful sample. Tool of data collection: Two tools were employed to gather data., as follow: Patients’ Interviewing Questionnaire and Patient Self-Care Practices. Results: revealed that the most (90%) of patients in the study group had a satisfactory total level of knowledge following the implementation of the discharge plan, compared to less than one-fifth (16.7%) of patients in the control group. Additionally, the most of patients (90.0%) in the study group had a satisfactory level regarding total self-care practices following the implementation of the discharge plan, while more than one-tenth (13.3%) of patients in the control group had a satisfactory level. Conclusion: Implementation of discharge planning regarding LDH surgery had a statistically significant effect in improving self-care practices, and knowledge of patients in the study group compared to the control group. There was statistically significant positive correlation between total self-care practices, and total knowledge among the patients in the study group post implementation of discharge plan, which supported the stated hypothesis. Recommendation: Further research is needed to assess the effects of preoperative education on surgical outcomes and self-care activities in patients undergoing LDH surgery.
