Cochrane reviews

Slow subcutaneous injection of LMWH appears to have slightly lower pain intensity and bruising size at the injection site compared with fast injection Slow Versus Fast Subcutaneous Injection of Lmwh.
Alerts, such as computerized reminders and stickers on patient charts, appear to increase the use of thromboprophylaxis in hospitalized medical and surgical patients Interventions for Increasing the Use of Thromboprophylaxis in Hospitalized Patients.
Use of thromboprophylaxis may prevent deep vein thrombosis in severe trauma patients Thromboprophylaxis for Trauma Patients.
Primary prophylaxis for venous thromboembolism (VTE) with LMWH appears to reduce the incidence of symptomatic VTE in ambulatory cancer patients receiving chemotherapy. It has no effect on 1-year total mortality but may increase the risk of major bleeding Primary Prophylaxis for Venous Thromboembolism in Ambulatory Cancer Patients Receiving Chemotherapy.
Direct thrombin inhibitors (ximelagatran, dabigatran and desirudin) may be as effective as LMWH and vitamin K antagonists in the prevention of major venous thromboembolism in total hip or knee replacement but seem to show higher mortality and cause more bleeding than LMWH Dabigatran Versus Lmwhs for Thromboprophylaxis after Total Hip or Knee Replacement.
Prolonged thromboprophylaxis with low-molecular weight heparin (LMWH) reduces the risk of venous thromboembolism compared to thromboprophylaxis during hospital admittance only, without increasing bleeding complications after major abdominal or pelvic surgery, at least in cancer patients Prolonged Thromboprophylaxis with Low Molecular Weight Heparin for Abdominal or Pelvic Surgery.
Use of low molecular weight heparin (LMWH) in outpatients reduces the number of venous thromboembolic events when a plaster cast or brace is required, also for patients with below-knee casts Low Molecular Weight Heparin in Patients with Lower-Leg Immobilization.
Combined mechanical intermittent pneumatic leg compression and pharmacological prophylaxis appear to decrease the incidence of deep vein thrombosis when compared to compression, and incidence of pulmonary embolism when compared to anticoagulation Combined Intermittent Pneumatic Compression and Pharmacological Prophylaxis for Prevention of Venous Thromboembolism.
Heparin plus graduated compression stockings appears to be better than either treatment alone for thrombus prophylaxis in colorectal surgery Thrombus Prophylaxis in Colorectal Surgery.
Low molecular weight heparin MWH may reduce the incidence of distal DVT diagnosed by sonogram in adults undergoing knee arthroscopy Interventions for Preventing Venous Thromboembolism in Adults Undergoing Knee Arthroscopy.
There is insufficient evidence to make a definitive conclusion about the use of anticoagulant drugs (with or without mechanical devices) for deep vein thrombosis prophylaxis in patients undergoing abdominal aortic surgery Interventions for Preventing Venous Thromboembolism Following Abdominal Aortic Surgery.

Other evidence summaries

Low-molecular weight (LMWH) or unfractionated heparin combined with mechanical prophylaxis may be more effective than heparin alone, and high-dose LMWH may be more effective than low-dose LMWH in preventing deep venous thrombosis in cancer patients undergoing surgery Deep Venous Thrombosis Prophylaxis in Cancer Patients.
