Research supports changing practice from heparinized to saline flushes for adults, yet heparin continues to be used in clinical practice. The primary aim of this study was to test the effectiveness of a community level innovation diffusion intervention as a method of stimulating research utilization at three acute care facilities in one community simultaneously. The change advocated was the flushing of intermittent intravenous devices (IID) with saline rather than heparin. Pilot IID units were chosen on which to test the change from the use of heparin to saline flushes. The innovation focused on staff empowerment and was implemented in five phases. The change to saline flushes was successful and has been maintained.
