Conclusions: Flushing practices for vascular access device flushing appear to vary widely.
Specific areas of practice that warrant further investigation include questions about the
efficacy of heparin for central device flushing, increasing adherence to the recommended
10 mL diameter syringe use, increased use of prefilled flush syringes, identifying and
standardising optimal volumes and frequency of flushing, and improving documentation
of flush orders and administration.
