UK national survey of venous thromboembolism prophylaxis in ankle fracture patients treated with plaster casts

Abstract

Ankle fractures are one of the commonest orthopaedic injuries. A substantial proportion of these are treated non-operatively at outpatient clinics with cast immobilization. We conducted this survey to assess the current practice in UK regarding thromboembolism prophylaxis in these patients. A telephonic survey was carried out on junior doctors within orthopaedic departments of 56 hospitals across the UK. A questionnaire was completed regarding venous thromboembolism risk assessment, prophylaxis, hospital guidelines, etc. 84% (n=47) hospitals did not routinely use any prophylaxis for these patients, while 7% (n=4) hospitals used chemo-prophylaxis. Only 5.3% (n=3) hospitals had DVT prophylaxis guidelines regarding these patients while other 9% (n=5) hospitals were in process of developing such guidelines. In 64% (n=36) hospitals, no formal DVT risk assessment was carried out. A large variation exists across NHS hospitals and a poor risk assessment is being carried out in these patients. Development of local guidelines and extension of national guidelines to include high risk outpatients may improve the situation.
