Incidental findings OSCE — trauma CT cyst counselling and cascade control

Candidate brief

You have 10 minutes. The examiner plays a parent. A nurse may give observations showing a stable child. Your tasks: [1]

1. Confirm the trauma status and the meaning of the incidental cyst. [4]
2. Classify the finding (act / plan / observe / stop) with reasoning. [3] [5]
3. Counsel about cascade risk if every incidental is chased tonight. [3] [6] [10]
4. Agree a safety net and follow-up owner. [1] [5]
5. Deliver a one-minute handover that includes residual risk. [3] [7]

Scripted parent lines

• “Does this mean cancer?” [1]
• “Why won’t you do every blood test and another scan now?” [1]
• “If you miss something we will never forgive you.” [1]

Marking domains

Clinical reasoning (30%). Restates original trauma question; does not abandon trauma residual risk; correctly treats cyst as incidental; chooses non-urgent bin unless red features appear. [4] [1] [7]

Stewardship (25%). Explains overdiagnosis/cascade concepts in plain language without jargon dumps; avoids maximal same-night cascade; does not claim incidentals never matter. [2] [3] [6]

Communication (25%). Names fear; uses teach-back; concrete return triggers (pain, fever, haematuria, systemic change); avoids false certainty and rare-disease catalogues. [5] [1]

Handover and safety (20%). States finding, bin, owner, timing, residual trauma and medical risks; no copy-forward cancer label. [3] [7]

Exemplar counselling fragment

“The CT answered the injury question we needed. It also showed a small simple cyst that was not why we scanned. Most findings like this are watched rather than operated on tonight. Doing every extra test now is more likely to create false alarms than to help. We will still watch for warning signs of both the injury and any rare problem with the cyst, and here is exactly who follows this up and when.” [4] [3] [1]

Common fails

• Ordering PET/CT or “cancer bloods” to relieve parental anxiety alone. [3] [8]
• Dismissing parents as difficult without residual-risk plan. [5]
• Writing “renal cyst — malignancy” into the problem list. [1]
• Forgetting evolving trauma complications while debating the cyst. [4] [7]
• Equating continuous monitoring philosophy from other wards with mandatory cascade here. [9]
