Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar after assessing the mother. [1]
Candidate instructions. Explain postpartum psychosis as a medical-psychiatric emergency that is highly treatable; outline why admission (ideally mother-baby unit if available and safe) is needed; describe dual risk planning for mother and infant honestly; explain sequential treatment principles (sleep, antipsychotic, lithium with monitoring, ECT if required) and lactation trade-offs; address child-protection fears without promising absolute secrecy if acute risk; discuss high recurrence risk and prevention for a future pregnancy. Check understanding. The examiner plays the partner. [2][5][3]
Candidate scenario
Mother meets clinical criteria for postpartum mania/psychosis day 6 after first birth. No fever. Family history of bipolar in a first-degree relative. Partner wants clear answers about permanence, infant removal, breastfeeding, and future children. [1]

- Accurate emergency explanation of PPP and bipolar link
- Clear dual risk and admission/MBU rationale

Reveal assessor key
Open. Acknowledge fear and exhaustion; thank him for bringing her in early. Agenda-set. [1]
Explain. This is postpartum psychosis, a rare but serious illness that often starts in the first two weeks after birth and is strongly linked to bipolar vulnerability. It is not "bad parenting" and it is usually highly treatable with hospital care.[1][2]
Setting and safety. She needs urgent inpatient care. If a mother-baby unit bed is available and safe, that allows treatment while supporting bonding under supervision; otherwise a general ward with a clear infant-care plan. We assess both her suicide/self-harm risk and the baby's safety continuously. Unsupervised care is not safe while she believes the baby is possessed.[5][1]
Treatment. Restore sleep; antipsychotic medication for psychosis/mania; lithium is often added for affective postpartum psychosis with blood tests and level checks; ECT is available if illness is life-threatening or not responding. Breastfeeding decisions are individual — safety of mother and baby comes first and temporary formula may be safest while medicines are started.[2][6]
Safeguarding. Services aim to support families to recover together when safe. If risk became acute and could not be managed, protective agencies might need involvement — we would try to work openly with them. Seeking help is protective, not a reason for automatic permanent removal.[1]
Future pregnancies. Risk of recurrence after PPP is high without a plan. Before another pregnancy we arrange preconception counselling, sleep plans, early-warning signs, and often proactive postpartum medication strategies (including lithium decisions) with obstetric partners.[3][4]
Close. Summarise, crisis contacts, invite questions, teach-back. [6]
