Women with pre-existing medical and obstetric problems are at increased risk of complications in pregnancy. Such high-risk pregnancies result in increased maternal, fetal and neonatal morbidity and mortality. In 2008, the National Institute for Health and Clinical Excellence (NICE) issued guidelines for routine antenatal care of healthy pregnant women. Common medical conditions that confer a higher risk to the pregnancy but are often unrecognised at referral are obesity and mental health disorders. Integrated care pathways can be used as tools to incorporate local and national guidelines into everyday practice, manage clinical risk and meet the requirements of clinical governance. Training programmes for midwives, obstetricians, GPs and psychiatrists should include perinatal psychiatric disorders. The needs of the local population must be taken into account when planning a service in terms of providing the correct care, particularly in areas where there are large numbers of women from migrant and ethnic minority populations.
