TP9.2.11Venous Thromboembolism Assessment and Thromboprophylaxis in Pregnant Women admitted to Hospital under Non-Obstetric Specialties

Aims During a non-obstetric admission, there is minimal awareness amongst other specialties regarding the need to reassess venous thromboembolism (VTE) prophylaxis requirements. The primary aim of this study was to review whether perinatal patients are accurately assessed for VTE risk factors during non-obstetric admissions and being prescribed appropriate thromboprophylaxis upon discharge. Methods Data collection was carried out by retrospectively identifying all admissions of pregnant women in hospital under a non-obstetric team over a period of six months. Patients were scored according to their individual risk factors related to pregnancy and the admission. Comparison was made between the recommended and actual prophylaxis given. Results 152 patients were included in the study. Only 13 women received appropriate VTE management whilst 35 patients were deemed high-risk and did not receive prophylaxis. VTE assessment was not documented in nearly 60% of patients. 68% of patients were found to be at intermediate risk. Conclusion Reassessment for risk of VTE in antenatal and postnatal patients is poorly documented when managed by non-obstetric led teams. Women with both established and transient risk factors for VTE are not receiving appropriate thromboprophylaxis. Raised awareness of this specific problem is required amongst non-obstetric teams. Key Statement Appropriate thromboprophylaxis is vital at the point of admission of a pregnant patient to hospital as this is associated with an 18-fold increased risk of VTE. Further improvements need to be made in order to educate non-obstetric teams caring for obstetric patients regarding the importance of VTE risk assessment.
