Implementing an emergency department vascular access team: A quality review of training, competency, and outcomes

Peripheral intravenous catheters are frequently used devices in emergency departments. Many patients now present with difficult anatomy and are labeled as difficult intravenous access patients. A common technology to address this challenge is ultrasound. While studies have examined the ability to train emergency staff, few have addressed how this should be done and the outcomes associated with such training. No studies were found with dedicated vascular access specialist teams in emergency departments. An emergency department vascular access specialist team was formed at a hospital in Bangor, Maine, United States to train, validate, and proctor clinicians with ultrasound-guided peripheral intravenous devices. A quality review of this process was compiled and determined that appropriate clinicians with dedicated training and guidance can achieve higher levels of procedural success. Furthermore, evidence substantiates that frequent practice is linked to a higher quality of care and that a significant need for such teams is present. This review examines how a team was implemented and its impact both department- and facility-wide. It is possible that hospitals benefit from the services of vascular access specialists to provide higher quality care. Successful implementation of such specialist teams requires foundational knowledge and skills in vascular access with ongoing quality measures to ensure competency and compliance with evidence-based practices.

Pre- and post-review of a standardized ultrasound-guided central venous catheterization curriculum evaluating procedural skills acquisition and clinician confidence

Background:

To evaluate novice and expert clinicians’ procedural confidence utilizing a blended learning mixed fidelity simulation model when applying a standardized ultrasound-guided central venous catheterization curriculum.

Methods:

Simulation-based education and ultrasound-guided central venous catheter insertion aims to provide facility-wide efficiencies and improves patient safety through interdisciplinary collaboration. The objective of this quality improvement research was to evaluate both novice (<50) and expert (>50) clinicians’ confidence across 100 ultrasound-guided central venous catheter insertion courses were performed at a mixture of teaching and non-teaching hospitals across 26 states within the United States between April 2015 and April 2016. A total of 1238 attendees completed a pre- and post-survey after attending a mixed method clinical simulation course. Attendees completed a 4-h online didactic education module followed by 4 h of hands-on clinical simulation stations (compliance/sterile technique, needling techniques, vascular ultrasound assessment, and experiential complication management).

Results:

The use of a standardized evidence-based ultrasound-guided central venous catheter curriculum improved confidence and application to required clinical tasks and knowledge across all interdisciplinary specialties, regardless of level of experience. Both physician and non-physician groups resulted in statistically significant results in both procedural compliance ( p < 0.001) and ultrasound skills ( p < 0.001).

Conclusion:

The use of a standardized clinical simulation curriculum enhanced all aspects of ultrasound-guided central venous catheter insertion skills, knowledge, and improved confidence for all clinician types. Self-reported complications were reported at significantly higher rates than previously published evidence, demonstrating the need for ongoing procedural competencies. While there are growing benefits for the role of simulation-based programs, further evaluation is needed to explore its effectiveness in changing the quality of clinical outcomes within the healthcare setting.

Hemodialysis Catheter Insertion Without Chest X-Ray: Review of a 24-Month Study

Acute care hemodialysis catheters have traditionally been validated for use through chest X-ray interpretation. This study was implemented to evaluate if hemodialysis catheters can be placed safely and accurately, utilizing an electrocardiogram plus doppler or dual vector positioning system to validate for use. Over a 24-month period hemodialysis catheters were inserted and validated by utilizing a dual vector positioning system instead of chest X-ray. During the study period, 260 hemodialysis catheters were inserted without chest X-ray and validated for use via the dual vector positioning system. An additional 74 inserted catheters required follow-up chest X-rays because of failure to obtain technological validation. During the study period, no patients had a pneumothorax or hemothorax complication subsequent to catheter placement. The use of a dual vector positioning system in this study demonstrated optimal hemodialysis catheter insertion can be done with no X-ray and no increase in mechanical complications.

Repositioning of Central Venous Access Devices using a High-Flow Flush Technique - a Clinical Practice and Cost Review

Background

Malpositioned central venous access device (CVAD) tip locations can cause significant mechanical and chemical vessel-related injuries and complications if left in inappropriate positions. The aim of this study is to determine the use of a high-flow flush technique (HFFT) in successful correction of malpositioned catheters into the lower superior vena cava or cavoatrial junction and provide a cost comparison to interventional/fluoroscopic-based repositioning.

Methods

This is a retrospective chart and radiographic review of all inserted CVADs found malpositioned between 1996-2014 in a multi-specialty 1000-bed tertiary trauma center in Sydney, Australia. 7450 CVADs placed by a nurse-led vascular access service were reviewed. Catheters repositioned pre-2010 were excluded owing to radiology repositioning interventions.

Results

There were 3996 peripherally inserted central catheters (PICCs) and 3454 centrally inserted central catheters (CICCs) placed. Seventy-four were malpositioned post-2010. Of these, 53 devices were repositioned using the studied technique; 86% (46/53) of catheters were successfully repositioned on the first HFFT attempt. There was supportive evidence that device insertion side is important in potential catheter malposition.

Conclusions

Clinical outcomes suggest that CICCs and PICCs may be successfully repositioned utilizing this technique, with no adverse events associated and a prospective cost saving benefit when compared to interventional-based repositioning procedures.
