Abstract

Venous thromboembolism (VTE) is a leading cause of maternal mortality. The risk increases with increasing maternal age, mode of delivery and medical co-morbidities. Thromboprophylaxis with low molecular weight heparin (LMWH) has been shown to be both safe and efficacious. The aim of this study was to prospectively investigate the incidence of maternal risk factors in pregnant women admitted to hospital, to calculate their VTE risk status and to investigate if they were receiving appropriate thromboprophylaxis. All patients admitted to the participating hospitals on the day of investigation were assessed for risk of VTE on the basis of hospital chart review. Five Hundred and forty women were recruited from 16 hospitals. Almost 32% (31.7%) were receiving thromboprophylaxis with LMWH. Just under 80% of patients were on the correct thromboprophylaxis strategy as defined by the RCOG guideline but 49% were under-dosed. The odds of receiving appropriate thromboprophylaxis were significantly increased if the woman was >35 years 0or with parity>3.
