Redesign of a weight-based heparin protocol for improved outcomes in a community hospital.

Heparin has long been used to minimize complications of a variety of disorders and reaching a therapeutic level within 24 hours has been shown to improve patient outcomes. However, the dosing of heparin to reach a therapeutic level has been controversial. At our institution a weight based heparin nomogram was in place, however an initial data analysis revealed a large percent of the initial aPTT levels were above therapeutic range.
