Impact of an education campaign on management in pregnancy of women infected with a blood-borne virus.
OBJECTIVE
To assess obstetricians' antenatal screening practice for blood-borne viruses (HIV, hepatitis B and C viruses [HBV and HCV]) and knowledge about management during labour and risk of transmission via breastfeeding for infected women after an educational intervention, Australia.


METHODS
Cohort study, with surveys before and after an educational intervention.


METHODS
Survey 1 was mailed in 2002-2003 to all 767 Fellows registered with the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG), and Survey 2 was mailed in 2004 to the 743 of these Fellows who were still practising.


METHODS
Multifaceted intervention with mail-out of survey results and a summary of recommended management, publication of two review articles in the RANZCOG journal, and an oral presentation at the RANZCOG annual scientific meeting.


METHODS
Self-reported frequency of antenatal screening for blood-borne viruses, change in practice based on a woman's infection status, and advice given about risk of virus transmission via breastfeeding in Survey 2, compared with Survey 1.


RESULTS
Survey 2 (response rate, 68%) found increases from the previous survey in the proportion of respondents reporting they always offered antenatal screening for HIV, from 51% to 59%, and for HCV, from 60% to 69% (P = 0.001 for both). For women with HIV infection, the proportion of respondents always recommending elective caesarean section increased from 37% to 49% (P = 0.001) and always avoiding rupture of membranes increased from 33% to 49% (P < 0.001). The proportion who reported advising (incorrectly) that breastfeeding is associated with increased risk of transmission to the infant decreased from 34% to 25% for HBV (P = 0.01) and from 47% to 39% for HCV (P = 0.03).


CONCLUSIONS
The frequency of antenatal testing for HIV and HCV is increasing in Australia. Knowledge about interventions to reduce mother-to-child transmission of HIV and knowledge of the risk of HBV and HCV transmission via breastfeeding improved after a relatively simple educational intervention.
