Thromboprophylaxis for caesarean section—how can uptake and coverage be improved?

Abstract

The objective of this study was to determine the proportion of patients requiring thromboprophylaxis and evaluate adherence to local protocols on thromboprophylaxis after caesarean section. This was a retrospective audit of 200 consecutive patients undergoing caesarean section between January and March 2002. The study was carried out at two obstetric units in Hull. We evaluated the proportion of patients requiring prophylaxis, appropriate and inappropriate treatment given and those omitted from receiving prophylaxis. Adherence to a risk assessment protocol was also assessed. The majority of women (84.5%) had at least one risk factor for thromboembolism. Use of a checklist did not increase the appropriate use of thromboprophylaxis and did not reduce inappropriate use. The checklist was used appropriately in only 54% of cases. Thromboprophylaxis has not been associated with problems if given after operation, thus the inappropriate administration is probably not a serious mistake. Universal prophylaxis with low molecular weight heparin would prevent at-risk women being missed and should be considered.
