Assessing Anesthesia Providers' Perceptions of Ultrasound-Guided Arterial Catheterizations: A DNP Project

Abstract

CRNAs frequently perform perioperative arterial catheterizations. Despite multiple studies supporting the advantages of ultrasound guidance, no formal processes are consistently followed, leaving CRNAs to use clinical judgment and personal preferences when selecting methods for arterial catheterization procedures. Currently, there is a lack of understanding regarding CRNA knowledge of and preference for utilization of ultrasound technology for perioperative arterial catheterization. The purpose of this DNP quality improvement project was to develop, implement, and evaluate the perceived adequacy of an educational resource designed specifically for CRNAs for improving awareness of and preference for utilization of ultrasound for arterial catheterization. The project was implemented at a large academic hospital in the southeastern United States. Educational materials, including a PowerPoint presentation and handout, were provided to participating CRNAs to utilize in their clinical practice. Review of pre- and post-implementation surveys demonstrated increased awareness of the advantages of ultrasound and improved confidence in ultrasound utilization. The perceived barrier to ultrasound utilization in arterial catheterizations was reported by 100% of respondents as the lack of available ultrasound machinery. Data analysis was limited by the small sample size, partial CRNA participation, and uneven number of respondents to the pre- and post-implementation surveys. Future projects should incorporate a larger sample size, a hands-on ultrasound training and skills workshop, and a thorough assessment of cost-related factors that impact perioperative arterial catheterizations including procedure duration, material costs, surgical delays, and ultrasound equipment.
