Pregnancy and the postnatal period 

Antenatal and intrapartum care have become much more the domain of secondary care over the last few decades. Only 2% of births take place at home and the concept of the ‘obstetric flying squad’ is now historical, with the understanding that it is safer to transport women who are having obstetric complications to a hospital, rather than trying to bring the hospital to the woman. We will however see pregnant women who present with new symptoms, or a worsening of existing medical conditions, some of whom will be at a high-risk of pregnancy-related complications. We also need to consider the risk:benefit balance when prescribing in pregnancy, as many medicines are not licensed for pregnant women. The cohort of women who are having babies is, on average, older than in the past - the number of women who are pregnant in their 40s has doubled since the 1990s. An increasing number of pregnant women have multimorbidities, with one registry study showing that nearly one-quarter of pregnant women had multimorbidities which were active in the year before delivery. Significant issues include obesity, mental health problems and pre-existing cardiac disease, which were relevant to 82%, 25% and 10% of maternal deaths in the last MBRRACE-UK report respectively

Management in the post-natal period is largely done in primary care – this is a risky time for a woman, with the risk of venous thromboembolism being higher in the early post-natal period than during pregnancy. 52% of maternal deaths occur between 1 and 41 days after delivery. Whilst the risk from physical health decreases significantly as time passes, the same cannot be said for mental health risks; the 2023 MBRRACE-UK report showed that nearly 40% of deaths from mental health related causes occurred between six weeks and one year after the end of pregnancy. The professional carrying out a woman’s post-natal check should always specifically enquire about mental health. We are also responsible for the 6-8 week baby check, which may pick up significant health issues and for prescribing to breastfeeding women, where drug licences are often also notable by their absence.
