"Post-implementation audit compliance rates increased to 100% for the following criteria: the organization had a standardized flushing and locking solution protocol (0%), the CVAD lumen was locked upon completion of the final flush (10%), a single-dose system was used for flushing and locking the CVAD (60%), and preservative-free 0.9% sodium chloride was used to flush the CVAD (60%). Furthermore, the CVC occlusion rate decreased from 33% to 5%" Fan et al (2023).

IV flush best practice implementation project

Abstract:

Introduction and objectives: A central venous catheter (CVC)–a type of central venous access device (CVAD)–is the most common intervention for critical illnesses. Obstruction of the CVC can lead to fatal consequences. Thus, it is critical to maintain catheter lumen patency. The CVC occlusion rate in a hospital in Taiwan was 33%. This project aimed to decrease the CVC occlusion rate in acute care.

Methods: This project was conceptually informed by the JBI Evidence-Based Model of Healthcare, in particular, the conceptualization of evidence implementation as inclusive of context analysis, implementation, and evaluation of outcomes using evidence-based quality indicators. As part of the seven-phase implementation process, we used audit and feedback in a pre- and post-test design to measure baseline compliance. Based on the initial audit, we developed an implementation strategy responsive to the identified gaps in compliance. We then undertook a final audit to measure changes in compliance to evaluate our implementation effects. The JBI software, PACES, and the situational analysis software, GRiP, were used for data collection and implementation planning. There were six evidence-based criteria, with a sample size of 30 nurses for each criterion. The team carried out the project from September 2022 to January 2023.

Results: Post-implementation audit compliance rates increased to 100% for the following criteria: the organization had a standardized flushing and locking solution protocol (0%), the CVAD lumen was locked upon completion of the final flush (10%), a single-dose system was used for flushing and locking the CVAD (60%), and preservative-free 0.9% sodium chloride was used to flush the CVAD (60%). Furthermore, the CVC occlusion rate decreased from 33% to 5%.

Conclusions: The project successfully decreased the rate of CVC occlusion and increased the competence of nurses in acute care settings. The implementation of best practices in clinical care should focus on leadership, cross-department coordination, education, and innovation.
