I am in the process of updating our CVAD flushing policy and was wondering if anyone has recommendations. Our current policy is to flush every 8 hours with heparin and saline if not in use, but accessed. I do not believe that this is best-practice, but I have not found anything definitive that states this. If I am reading correctly, the INS standards does not indicate the frequency of flushes, but recommends facility policy. Bard’s recommendations are every 28 days if not in use or after each use. This is a company recommendation so I do not know if there is enough evidnce to implement their recommendations. Does anyone have any suggestions?
