Prolonged fever in a returned traveller — communication OSCE

Objectives

1. Establish that the stepwise fever after travel to Pakistan makes enteric fever the leading diagnosis. [1]
2. Explain why blood culture must be taken before antibiotics, without dismissing the parents' wish to start treatment. [1]
3. Counsel on XDR-aware empiric therapy and antibiotic stewardship in plain language. [8] [4]
4. Safety-net for the danger windows: perforation in weeks 3-4 and the red-flag abdomen. [1]
5. Outline public-health notification, exclusion and the typhoid conjugate vaccine for the family and future travel. [14]

Candidate brief

Twelve-minute station. Both parents are present and anxious; they have read about typhoid online and want immediate antibiotics. The child is alert but febrile at 39.4 degrees with a soft, mildly tender abdomen and no peritonism. Blood culture has not yet been taken. [1]

Expected actions

• Acknowledge the parents' worry and validate that enteric fever is a real possibility worth acting on. [1]
• Explain in plain language that the single most useful test is a blood culture, and that it must be drawn before antibiotics so we can identify the organism and choose the right drug. [1]
• Name the XDR concern from Pakistan travel honestly, and reassure that we have effective options (azithromycin first, with stronger drugs held in reserve). [8]
• Take the blood culture, start empiric azithromycin after it is drawn, and explain the plan to narrow once the laboratory returns susceptibilities. [4]
• Give clear, written safety-netting: return immediately for severe abdominal pain, a hard or rigid abdomen, vomiting blood or black stools, drowsiness, or worsening fever. [1]
• Explain that enteric fever is notifiable, that the child should stay off school until cleared, and that the typhoid conjugate vaccine protects future travel and close contacts. [14]

Marking

Pass: validates concern; insists on blood culture before antibiotics; explains XDR and stewardship in plain language; clear safety-netting for perforation; public-health and vaccine plan. [1] [4] [14] Fail: starts antibiotics before culture; dismisses parents; no XDR reasoning; rigid abdomen missed or attributed to gastro; no notification, exclusion or vaccine discussion. [8]
