Developing an Impella Education Program for the Critical Care Registered Nurse

Jackson, Sara 01 January 2018 (has links)
Every year, hundreds of thousands of patients have coronary angiograms performed in the United States. The Impella is a percutaneous ventricular support device that provides hemodynamic support for patients if hemodynamic instability occurs during the procedure. The critical care nurse is responsible for the recovery and management of the patient with the Impella device in place. The purpose of this scholarly project is to provide registered nurses (RN) who have not previously managed the Impella device with the appropriate education in order to demonstrate competency. The program demonstrated improved RN knowledge about the Impella and increased confidence when managing the Impella device and controller. King's goal attainment theory was used as a framework to develop nurse-patient collaboration. Kirkpatrick's 4-level training evaluation model provided the framework for evaluation of the RN educational program. The sources of evidence included literature and an expert panel that was recruited to evaluate the material prior to implementation of the educational program. The data were analyzed by comparing the results of the preeducational and posteducational questionnaires. The paired t test demonstrated statistical significance based on the scores from the pre- and post-tests taken by the RNs before and after the Impella educational program as p < .001. Increased RN confidence was demonstrated by p < .001, while a change in RN attitude towards the Impella established improvement by p < .001. Providing professional development opportunities has been shown to benefit RNs to allow the delivery of safe care while allowing for positive social change by impacting patient lifestyle and outcomes.

Rationale and Design of JenaMACS—Acute Hemodynamic Impact of Ventricular Unloading Using the Impella CP Assist Device in Patients with Cardiogenic Shock

Introduction: Cardiogenic shock due to myocardial infarction or heart failure entails a reduction in end organ perfusion. Patients who cannot be stabilized with inotropes and who experience increasing circulatory failure are in need of an extracorporeal mechanical support system. Today, small, percutaneously implantable cardiac assist devices are available and might be a solution to reduce mortality and complications. A temporary, ventricular, continuous flow propeller pump using magnetic levitation (Impella®) has been approved for that purpose. Methods and Study Design: JenaMACS (Jena Mechanical Assist Circulatory Support) is a monocenter, proof-of-concept study to determine whether treatment with an Impella CP® leads to improvement of hemodynamic parameters in patients with cardiogenic shock requiring extracorporeal, hemodynamic support. The primary outcomes of JenaMACS are changes in hemodynamic parameters measured by pulmonary artery catheterization and changes in echocardiographic parameters of left and right heart function before and after Impella® implantation at different support levels after 24 h of support. Secondary outcome measures are hemodynamic and echocardiographic changes over time as well as clinical endpoints such as mortality or time to hemodynamic stabilization. Further, laboratory and clinical safety endpoints including severe bleeding, stroke, neurological outcome, peripheral ischemic complications and occurrence of sepsis will be assessed. JenaMACS addresses essential questions of extracorporeal, mechanical, cardiac support with an Impella CP® device in patients with cardiogenic shock. Knowledge of the acute and subacute hemodynamic and echocardiographic effects may help to optimize therapy and improve the outcome in those patients. Conclusion: The JenaMACS study will address essential questions of extracorporeal, mechanical, cardiac support with an Impella CP® assist device in patients with cardiogenic shock. Knowledge of the acute and subacute hemodynamic and echocardiographic effects may help to optimize therapy and may improve outcome in those patients. Ethics and Dissemination: The protocol was approved by the institutional review board and ethics committee of the University Hospital of Jena. Written informed consent will be obtained from all participants of the study. The results of this study will be published in a renowned international medical journal, irrespective of the outcomes of the study. Strengths and Limitations: JenaMACS is an innovative approach to characterize the effect of additional left ventricular mechanical unloading during cardiogenic shock via a minimally invasive cardiac assist system (Impella CP®) 24 h after onset and will provide valuable data for acute interventional strategies or future prospective trials. However, JenaMACS, due to its proof-of-concept design, is limited by its single center protocol, with a small sample size and without a comparison group.
