Patency, assessment, and management of central catheter occlusion in adult patients in the intensive care unit: a best practice implementation project.

Introduction: Cannulation with a central venous catheter (CVC) is a common procedure used in critical care. One of the main complications is occlusion, which can lead to delayed treatment, prolonged hospital stay, and increased health care costs.

Objective: The aim of this project was to promote evidence-based practice for nurses caring for patients with a CVC in a Spanish intensive care unit. The project also aimed to reduce CVC occlusion and ensure CVC patency.

Methods: This project was guided by the JBI Model of Evidence-based Healthcare and the JBI Evidence Implementation Framework. Seven phases were followed using evidence-based auditing and feedback. The JBI Practical Application of Clinical Evidence System (PACES) and Getting Research into Practice (GRiP) tools were used to support data collection, data analysis, and implementation planning.

Results: After project implementation, the following results were obtained. Criterion 1 (assessing the CVC, flushing, and aspirating) reached 100% compliance in both audits. Criterion 2 (occlusion documentation) showed a modest improvement, rising from 13.33% to 36.67%. Improvement for Criterion 3 (the need for a policy and protocol) was excellent, rising from 0% at baseline to 100% following implementation. Criterion 4 (rapid instillation of an appropriate thrombolytic agent if a CVC is occluded) remained at 0% compliance in both audits. Criterion 5 (continuing education for health care professionals) improved from 10% to 60%. Criterion 6 (flushing and locking before procedures) improved from 90% to 100%.

Conclusion: The project objectives were largely met and resulted in a protocol, which has been shared with other departments within the hospital. The implementation of best clinical practice will be continued, including the use of thrombolytic agents.
