Heart Failure (HF) is associated with substantial financial challenges resulting in exorbitant yearly costs, and frequent readmits to the emergency department. Postdischarge HF self-management is crucial to improve client outcomes. The purpose of this quantitative, quasi-experimental, project was to examine whether the implementation of an RN-facilitated post-discharge phone call that focused on HF self-management strategies reduced return emergency department (ED) visits within 72 hours in an urban South Florida hospital. Orem's self-care theory and the Meleis transition model were used for their success in managing chronic illnesses such as HF. Both examined if an RN facilitated post-discharge telephone call that focused on HF self-management strategies impacted HF patients. The sample comprised 62 patients (n=32 comparison group, n=30 post-intervention) ages 18-89 diagnosed with HF. A Chi-square analysis examined the difference between the number of ED readmits for HF patients before and after the intervention. The intervention lowered the ED readmit rates but was not statistically significant, X²(1) = .60, p =0 .44. Although statistical significance was not found with the post-discharge phone calls, there was a reduction (5.8%) in the number of readmissions within 72-hours. Therefore, the finding suggests that if the project was replicated utilizing the same process for a longer period, statistical and clinical significance might be achieved. Additionally, the project provided the organization some insight into the need for sustainability of the project.
