Station brief
Format. Emergency management station, approximately 12 minutes. You are the on-call gynaecology registrar in the emergency department. The patient has just arrived with a referral letter from the IVF clinic six days after egg collection. A senior nurse is with you; the gynaecology consultant is 20 minutes away and has been called. The assessor will run the clock and feed you new observations. [12]
Candidate instruction. Lead the assessment and management of severe ovarian hyperstimulation syndrome. Verbalise your severity grading, your fluid and thrombosis plan, your paracentesis decision, your thresholds for escalation, and your communication with the patient and her partner. [12]
