To the Editor: Giles et al1 have “poisoned the well” for future research by attacking the obstetricians who took the trouble to help them with their study on management of hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV.

Many of the discrepancies noted between current practice and the recommendations/guidelines are easy to explain:

• Failure to screen. Many obstetricians were told that it is discriminatory to screen for HIV and HCV without extensive pretest counselling. The advice is obsolete, but old habits die slowly.

• Failure to recommend caesarean section for women with HIV. Many obstetricians have never seen a case of HIV and would most certainly phone for advice if the situation arose.

• Failure to promote breastfeeding. Many obstetricians leave advice on breastfeeding to the midwives and paediatricians. However, the article does concede that mother-to-baby transmission is a theoretical risk, so patients are entitled to be informed.

• Failure to adhere to guidelines. Many obstetricians regard guidelines issued by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) as just that — guidelines, not gospel.
