Patients Preference With Self-Injection: The PRISM Study

Summary

The purpose of this study is to determine which short-acting blood thinner (low-molecular-weight heparin \[Enoxaparin\] or unfractionated heparin) is associated with less discomfort and bruising when given as a subcutaneous (under the skin) injection before and after a planned surgery or procedure in patients who temporarily stop warfarin.
