This research paper conducts an in-depth evaluation in order to improve nurses' comprehension of self-care management and patient discharge education for patients with Heart Failure (HF). It also discusses the reasons and obstacles to nurses for increasing their knowledge, attitude, and practice to support improved health outcomes and reduce readmission. In order to prevent readmission and re-hospitalization through discharge training, this study aims to raise awareness about the gaps in knowledge, practice, and attitude among nurses working with patients admitted with heart failure. The study evaluates the nurses' knowledge and aids in the education that heart failure patients must receive. By using effective medication management and post-discharge instructions, heart failure symptoms and disease progression can be controlled. Therefore, effective medication management following discharge is crucial for improving the quality of life, controlling symptoms, avoiding deterioration that triggers hospital readmission, and reducing death. Additionally, it is not always possible for healthcare team members to exchange enough accurate information with one another effectively. Numerous nations have emphasised the importance of the right health practices, optimistic attitudes, and suitable education among healthcare professionals to dispel misconceptions, increase confidence in providing support, and promote effective treatment.
