Perinatal psychiatry | Flashcards
What are 5 recommendations to prevent post-natal psychiatric deaths?
- All women should be screened at antenatal booking for a previous history of or current psychiatric disorder.
- Women with a previous history of serious affective disorder or other psychoses should be referred in pregnancy for psychiatric assessment and management even if they are well.
- Psychiatric services should have priority care pathways for pregnant and postpartum women. These will include a lowered threshold for referral and intervention, including admission and a rapid response time for women in late pregnancy and the first 6 weeks following delivery.
- Risk assessments of pregnant or postpartum women should be modified to take account of risk associated with previous history, the distinctive clinical picture of perinatal disorders and the violent methods of suicide.
- Caution needs to be exercised when diagnosing psychiatric disorder if the only symptoms are either unexplained physical symptoms or distress and agitation. This is particularly so when the woman has no prior psychiatric history or when she does not speak English or comes from an ethnic minority.
