PP101 Clinical And Economic Impact Of Flushing Vascular Access Devices With Pre-filled versus Manually-Prepared Saline Flush Syringes In Korea

Abstract

Introduction

Around 90 percent of hospitalized patients require vascular access devices (VADs) during hospitalization to administer fluids, medications and facilitate blood transfusions. After insertion, it is essential to maintain VADs to achieve optimal dwell time and reduce complications. Flushing of VADs is an integral part of catheter maintenance practices. With increasing cost burden on healthcare systems and nursing shortages, it is crucial to use time-and cost-saving technologies such as pre-filled flush syringes for common procedures namely VAD maintenance. This study aims to compare the clinical and economic impact of using pre-filled saline syringes versus manually-prepared saline syringes for flushing VADs in Korea.

Methods

A budget impact analysis was developed using Microsoft Excel to estimate the annual clinical and economic impact of pre-filled saline syringes and a base case scenario of flushing 100,000 VADs was modeled. Clinical impact was estimated for peripheral intravenous catheter (PIVC) failure, central line-associated bloodstream infections (CLABSIs), central line occlusion and nurse time. Economic impact was estimated for costs associated with flushing materials, additional length of stay (LOS) due to CLABSI, VAD replacement, and nurse-time. Global and local data sources were used for inputs. Assumptions include: (i) Distribution of 95 percent peripheral and 5 percent central VADs; (ii) 50 percent peripheral and 50 percent central VADs on intermittent therapy; and (iii) 3 flushes/catheter-day.

Results

Over a one-year timeframe, the model estimated 3,344 fewer PIVC failures, 15 fewer CLABSIs and 157 fewer occlusions with adoption of pre-filled saline syringes. Nurse time was reduced by 3,465 hours. Potential net annual savings from lower device cost, reduced complications, shortened LOS and increased nurse efficiency were estimated to be KRW23.7 million (USD178,957).

Conclusions

Using pre-filled saline syringes instead of manually-prepared syringes for flushing VADs may result in fewer complications, lower VAD utilization, nurse time saving and cost savings in Korea. This can potentially help improve patient outcomes, relieve nurses’ stress to some extent and help healthcare decision-makers to reallocate these cost savings to other life-saving technologies.
