The order set also revealed that low molecular-weight heparin rather than unfractionated heparin was the preferred drug for most patients who did not have a risk of bleeding as a contraindication.
The authors say that in factoring cost, the biggest expense is in implementation of an electronic health record system. But after that, "specific VTE prophylaxis algorithms for different patient populations would result in a relatively small incremental cost." The study looked at adult trauma patients treated between January, 2007 and December, 2010.
They concluded that "although many types of interventions have attempted to increase the use of prophylaxis, our proactive, mandatory approach has been shown to be one of the most effective. More passive strategies, such as laminated cards or educational efforts...were found to be relatively ineffective in increasing prophylaxis compliance rates."
