ACR Appropriateness Criteria® Central Venous Access Device and Site Selection.

The use of central venous access devices is ubiquitous in both inpatient and outpatient settings, whether for critical care, oncology, hemodialysis, parenteral nutrition, or diagnostic purposes. Radiology has a well-established role in the placement of these devices due to demonstrated benefits of radiologic placement in multiple clinical settings. A wide variety of devices are available for central venous access and optimal device selection is a common clinical challenge. Central venous access devices may be nontunneled, tunneled, or implantable. They may be centrally or peripherally inserted by way of veins in the neck, extremities, or elsewhere. Each device and access site presents specific risks that should be considered in each clinical scenario to minimize the risk of harm. The risk of infection and mechanical injury should be minimized in all patients. In hemodialysis patients, preservation of future access is an additional important consideration. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

ACR Appropriateness Criteria® Radiologic Management of Central Venous Access.

Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R. Bard, Inc, Salt Lake City UT), and implantable ports are available for this purpose. The device selected for central venous access depends on the clinical indication, duration of the treatment, and associated comorbidities. It is important for health care providers to familiarize themselves with the types of central venous catheters available, including information about their indications, contraindications, and potential complications, especially the management of catheters in the setting of catheter-related bloodstream infections. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Rapid Development and Implementation of an ECMO Program.

Extracorporeal membrane oxygenation (ECMO) is an established therapy in the management of patients with refractory cardiogenic shock or acute respiratory failure. In this report, we describe the rapid development and implementation of an organized ECMO program at a facility that previously provided ad hoc support. The program provides care for patients within the Emory Healthcare system and throughout the Southeastern United States. From September 2014 to February 2015, 16 patients were treated with either venovenous or venoarterial ECMO with a survival to decannulation of 53.3% and survival to intensive care unit discharge of 40%. Of the 16 patients, 10 were transfers from outside facilities of which 2 were remotely cannulated and initiated on ECMO support by our ECMO transport team. Complications included intracerebral hemorrhage, bleeding from other sites, and limb ischemia. The results suggest that a rapidly developed ECMO program can provide safe transport services and provide outcomes similar to those in the existing literature. Key components appear to be an institutional commitment, a physician champion, multidisciplinary leadership, and organized training. Further study is required to determine whether outcomes will continue to improve.
