VTE Prevention

Pregnant and Post Partum Women

Venous Thromboembolism (VTE) is a leading cause of maternal deaths in the developed world1 accounting for 3.2% of maternal deaths worldwide2 and 9.5% of maternal deaths in Australia3. While the risk of VTE has been found to be greater during the post-partum than the antenatal period,1,4 many VTEs still occur in the first trimester4. Early risk assessment and prevention is recommended.

Evidence suggests that all pregnant and post-partum women will benefit from VTE risk assessment and prescription of appropriate prophylaxis throughout their patient journey. This includes at:

  • the first antenatal review and/or booking
  • hospital admission for a non-pregnancy related complaint
  • hospital admission for a pregnancy-related complaint
  • the time immediately after birth (post-partum).

Assessing VTE Risk

A NSW Maternity Venous Thromboembolism Risk Assessment Tool has been developed. This helps guide clinicians to assess a woman’s risk and prescribe appropriate prophylaxis.

Information for Women & their Families

Women and their carers should be provided with information on the risks of VTE, how to prevent VTE and the signs and symptoms of a VTE.

The patient leaflet can be used at any time point during a women’s journey. It contains a ‘going home plan’ for women who will be discharged on  medication to prevent a VTE
