Towards evidence-based emergency medicine: best BETs from the Manchester Royal Infirmary. BET 3: thromboprophylaxis significantly reduces venous thromboembolism rate in ambulatory patients immobilised in below-knee plaster cast.

A short-cut review was carried out to establish whether ambulatory patients immobilized in a below knee plaster of paris cast and administered with a prophylactic dose anticoagulation with low molecular weight heparin; LMWH can benefit from a reduced risk of venous thromboembolism within the next 90 days One Cochrane Review was relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that the use of LMWH thromboprophylaxis is effective at reducing the incidence of VTE in these patients.
