Assessing volume status in patients with congestive heart failure (CHF) remains a difficult task. Newer technology, such as CardioMEMS, allows providers to download pulmonary artery pressure measurements from an implanted sensor. In a large rural emergency department (ED), lack of staff education on CardioMEMS made the device useless when a patient presented to the ED. The purpose of this project was to develop a staff education in-service to address the gap in practice. The theory used to guide development of an effective curricular program and instruction method was Knowles' theory of andragogy. Application of the analysis, design, development, implementation, and evaluation model ensured a robust and repeatable process of translation of research into practice. The practice-focused question involved whether a staff education in-service would improve staff members' ability to recognize the significance of CardioMEMS, appropriately use the device, and apply the data downloaded from the device to diagnose and guide treatment for patients with CHF. The design included a 5-point Likert scale pretest and posttest to evaluate staff knowledge and confidence to use the device in practice. On the pretest, three of 25 participants agreed that they were familiar with CardioMEMS. While all 25 participants agreed or strongly agreed that they encountered patients with CHF symptoms daily, all 25 reported strongly disagreeing or disagreeing that they were confident in CardioMEMS use. After the education, all participants agreed or strongly agreed that they were familiar with CardioMEMS, and 21 participants agreed or strongly agreed that they were confident in using the CardioMEMS device. This project will impact social change through improved CardioMEMS application in the ED. [The dissertation citations contained here are published with the permission of ProQuest LLC.
