Heart failure (HF) is a significant chronic medical condition that can impact overall quality of life and the financial stability of a healthcare system. Healthcare organizations are strategically working to identify educational methods that may reduce the burden of HF in the adult population. Ongoing patient education led by multidisciplinary teams remains the backbone of nursing efforts with nurses as key providers of HF education. Patients are stabilized in an acute-care setting and may be transferred to a post acute-care healthcare setting for short-term rehabilitation. The transitional care period is where patient education continues to be an important component for improving patient's understanding of self-care related to HF. Nurses' knowledge of HF principles has not been examined in the post acute-care healthcare setting. This four week descriptive correlational study assessed knowledge levels of nurses regarding evidence-based HF self-management principles utilizing the Nurses' Knowledge of Heart Failure Education Principles (NKHFP) survey. This study was designed to determine whether years of nursing experience, educational preparation, and licensure were characteristics impacting overall knowledge scores. The NKHFP survey was electronically distributed to 250 Registered Nurses (RNs) and Licensed Practical Nurses (LPNs) who care for HF patients in a post acute-care healthcare organization. A total of 92 RNs and LPNs completed an electronic NKHFP survey. There was no statistical significance between knowledge scores and licensure for nurses who completed the NKHFP survey (p = 0.05). The mean RN HF knowledge score was 14.67 (SD, 1.567). The mean LPN HF knowledge score was 14.19 (SD, 1.377). There was no statistical significance between knowledge scores and educational preparation for nurses who completed the NKHFP survey (p = 0.072). Finally, there was no statistical significance between knowledge scores and years of nursing experience for nurses who completed the NKHFP survey (p = 0.05).
