An audit of obstetricians' management of women potentially infected with blood-borne viruses.

ABSTRACT

OBJECTIVE: To assess obstetricians' current antenatal screening practices for blood-borne viruses (hepatitis B, hepatitis C and HIV) and how they manage pregnant women infected with a blood-borne virus. DESIGN AND PARTICIPANTS: National cross-sectional survey conducted between September 2002 and January 2003. All obstetricians (n = 767) registered with the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) were mailed a questionnaire assessing their antenatal screening practices and knowledge of management of women potentially infected with a blood-borne virus. OUTCOME MEASURES: Concordance of clinical practice with RANZCOG recommendations and current evidence-based guidelines. RESULTS: 523 obstetricians (68% response rate) completed the questionnaire. Fifty-one per cent of respondents said they would always offer HIV screening and 60% would always offer HCV screening. For HIV-infected women, 36% of obstetricians would always recommend elective caesarean section and 33% would always avoid rupture of membranes. Despite a lack of evidence, 34% of obstetricians advise patients that the risk of HBV transmission is increased with breastfeeding, and 47% give the same advice about HCV transmission. CONCLUSION: There is some discordance between the RANZCOG antenatal screening recommendations for HCV and HIV and current practice. Knowledge about the management of HIV-infected women could be improved, and more obstetricians need to be aware that current evidence suggests there is no increased risk of transmission of HBV or HCV with breastfeeding.
