Introduction

Around 70% of hospitalised patients require vascular access devices (VADs) during hospitalisation to facilitate the administration of fluids, medication and blood transfusions. Maintenance of such VADs is essential to reduce complications and risks to patients. This study aims to compare the clinical and economic outcomes between using manually prepared syringes and pre-filled saline syringes for flushing VADs in an Australian public hospital setting.

Methods

Budget impact analysis, developed using Microsoft Excel, was constructed to estimate the annual clinical and economic impact of flushing methods in a 500-bed hospital. Clinical outcomes included peripheral venous catheter (PIVC) failure, central line-associated bloodstream infection (CLABSIs) and occlusion. Economic outcomes included the costs associated with flushing materials, additional length of stay due to complication, VAD replacement, hospital-acquired complication penalty and nurse hours of flushing procedures. Global and local source data were used for inputs. Assumptions include: (1) 90% hospital occupancy rate; (2) Distribution of 90% peripheral and 10% central VADs; and (3) 90% peripheral and 50% central lines on intermittent therapy.

Results

The model estimated 2,583 less PIVC failures, 3 less CLABSIs and 142 less occlusions with the adoption of pre-filled saline syringes. Nurse hours were reduced by 4,040 hours. After accounting for an additional flushing material cost of AU$35,800, the potential net annual savings from reduced complications, shortened length of stay and increased nurse efficiency were estimated to be AU$12.6 million.

Conclusion

Using pre-filled saline syringes instead of manually prepared syringes for flushing VADs can result in less complications and potential cost savings.
