Module 15: Ultrasound (US) Applications in Dialysis Access
Dates available 9.20.2021-9.20.2022
“This activity is jointly provided by Global Education Group and Kidney Academy.”
This activity is supported by an educational grant from Philips.
The educational design of this activity addresses the needs of physicians and adjunct health care professionals (e.g. nurses, technologists) who treat kidney disease. Medical specialties addressed are relevant to transplant surgeons, radiologists, nephrologists, and vascular surgeons.
Statement of Need/Program Overview
End stage renal disease (ESRD), specifically dialysis access, is a complicated condition treated by a variety of medical specialists with varied perspectives and skillsets. Population growth predictions suggest that the burden of providing maintenance dialysis in coming decades will be daunting. Access to reliable and applicable training in ESRD / dialysis access is limited, and significant treatment protocol disparity exists globally among professionals. The specialties performing dialysis access are fragmented into siloed societies with limited opportunity to understand the viewpoints of the other specialties serving the same patient.
There is a significant need for a comprehensive foundational training program focused specifically on dialysis access. By offering education and training in dialysis access in general, and in this specific module about Ultrasound (US), knowledge can be standardized among providers, resulting in sound patient-centric decision making resulting in improved patient outcomes. Training will increase the understanding for all members of the dialysis access care team when treating patients to ensure the best possible treatment outcomes. Physicians need training related to the value of an integrated patient-centric model of dialysis delivery where all modes of RRT are considered in an individualized “Patient Life Plan”- centered pathway.
Many knowledge gaps exist among providers of dialysis access care in general and specifically to the understanding of Ultrasound (US). This unique multilevel color-coded hyperlinked training text is structured to meet the needs of increasing depths of learning and to fill needs depending on professional skillset.
The medical specialties engaged in dialysis access (General surgery, Transplant, Vascular Access, Interventional Radiology, Interventional Nephrology, Nephrology) have varied educational background and experience related to the use of ultrasound (US). Training aims to standardize this foundational knowledge among these various specialties in a broad effort to optimize the RRT for each patient.
Many physicians need basic foundational knowledge about how Ultrasound works, including the basic description of US physics, in relation for anatomy and blood flow. Included in this gap is a need to understand knobology (aka machine learning) and the proper selection of probes. Additional training in how to apply US in the practice of vascular mapping and access planning. Patient outcomes can improve with appropriate use of US in dialysis access and therefore physicians need training in US to impact patient outcomes related to this technology.
US is the key investigative tool in vascular mapping and in the recently percutaneously Endovascular techniques of AVF creation. To reach a high level of technical competence the operator must also obtain hands on training at institutions available around the world. As in all modules there is a pretest and a post study multiple choice test with a 75% required passing grade to download the CME certificate. A mandatory short survey is required before printing the CME certificate.
The modules describe in great details vascular access anatomy, the physiology and pathology of vascular access, how to perform US scanning of the many vascular access clinical scenarios from normal vascular access to stenosis and thrombosed access.US use for surveillance, needle cannulation, placing anesthetic arm blocks, central vein catheter placement are outlined in separate sections. One section is devoted to Intravascular Ultrasound (IVUS) in dialysis access. Section 21 summarizes a new technique (the modified Seldinger) for placing peritoneal dialysis catheters. This technique will be covered in an entire Module 16 - in progress.
After completing this activity, the participant should be better able to:
- Explain knobology (also known as, machine learning) and the proper selection of US probes.
- Explain how to apply US in the practice of vascular mapping and access planning.
- Discuss the guidelines and techniques for use of US in vascular access.
- Outline the uses of video media to document the finding of vascular mapping and US examination in forms and images
- Describe US metrics in assessing AV fistula maturation.
- Describe the use of US is for examining an occluded access and performing a post-operative follow-up scan.
- Identify situations where US guidance is essential for safety in dialysis access.
- Recognize the US appearance of AV grafts.
- List the diagnostic uses of US in dialysis access.
- Identify situations in which intravascular US (IVUS) may be beneficial related to improving the visualization in dialysis access.
- Describe the value of US in percutaneous PD catheter placement (ie: also known as modified Seldinger PD catheter placement technique).
- Describe the therapeutic applications of US in dialysis access, in particular, for new emerging technologies.
