Counselling a family about a medicine the child cannot take — OSCE

Station overview

A communication station testing whether the candidate can reframe a child's erratic disease control as a formulation-and-adherence problem, assess how the medicine is actually taken without blame, identify the barrier, and co-design a plan with the family and the pharmacist — without escalating the chronic dose (the classic error after a non-adherence-driven problem). The station is not about the pharmacology of tacrolimus per se; it is about the swallow, the taste, the regimen, and the shared plan. [2]

Candidate instructions

You are the general paediatric registrar in the transplant clinic. You have eight minutes. The 6-year-old's tacrolimus levels have been erratic for three months despite a correct weight-based dose. The parent has just told you the child spits out the bitter liquid and the half-tablets crumble. Your task is to assess how the medicine is actually taken, identify the formulation barrier, and co-design a formulation-and-regimen plan with the family and the pharmacist, while explicitly avoiding the trap of escalating the tacrolimus dose. The parent (played by an examiner or actor) is worried about graft rejection and a little defensive, expecting to be blamed. [1]

Encounter structure

1. Establish the parent's experience and worry first. Acknowledge that managing a transplant medicine is hard work, and that erratic levels are common and usually fixable — they are not a sign of failure. Ask open questions: walk me through a normal day of giving the medicine. [2]
2. Ask how the medicine is actually taken — openly and without blame. Use the single best question: how does he actually take this medicine? Explore the bitter liquid, the split tablets, the vomiting, the school-day timing, and any missed doses. Do not ask do you give it? — that invites a defensive yes. [2]
3. Reframe the problem for the parent. Name it plainly: the dose is right, but the form we're giving it in doesn't work for him, so the level bounces. This is a formulation problem we can fix together — it's not his fault, and it's not yours. [1]
4. Co-design the formulation plan. With the pharmacist, look for a taste-masked tacrolimus preparation, a dispersible form, or a mini-tablet at a weight-based strength; offer taste-masking strategies (chilling the liquid, following with a preferred drink); align the twice-daily doses with daily routines (breakfast, bedtime); provide dosing aids (oral syringe, pill box). [9]
5. Explicitly avoid the dose-escalation trap. Explain that you will not raise the tacrolimus dose to chase the erratic level, because once he takes it reliably the level will rise — escalating now risks toxicity. You will re-check the level after the formulation change. [2]
6. Set the follow-up and safety-net. Confirm the next clinic visit, the level-check timing, the warning signs to report (fever, reduced urine output, graft tenderness), and who to contact. Because tacrolimus is a narrow-therapeutic-index immunosuppressant, name the specialist pharmacist as part of the team. [2]

Marking domains

• Communication and rapport — acknowledges the worry, removes blame, uses open questions, checks understanding, invites questions. (High-weight domain.) [2]
• Reframing accuracy — correctly identifies the erratic level as a formulation-and-adherence problem rather than a pharmacology failure; does not blame the family; uses the word adherence appropriately. [1]
• Avoidance of the dose-escalation trap — explicitly states the dose will not be raised to chase the level, and explains why (toxicity once adherence returns). [2]
• Formulation plan — names an age-appropriate alternative (taste-masked liquid, dispersible, or mini-tablet), involves the pharmacist, offers taste-masking, simplifies the regimen, and provides dosing aids. [9]
• Safety-netting and follow-up — confirms the level re-check, the warning signs, the contact, and the specialist pharmacist's role for a high-risk medicine. [2]

Common pitfalls (what loses marks)

• Blaming the parent or child, or asking do you give it? in a tone that invites a defensive yes. [2]
• Escalating the tacrolimus dose to chase the erratic level — the classic and dangerous error. [2]
• Failing to reframe the problem as a formulation-and-adherence issue, and instead treating it as a pharmacology puzzle. [1]
• Prescribing an alternative formulation without involving the pharmacist or checking whether one exists. [9]
• Forgetting the safety-net and follow-up for a high-risk narrow-therapeutic-index medicine. [2]

Actor notes (for the examiner)

• If the candidate avoids asking how the medicine is actually taken, prompt directly: "Can I ask you — how does he actually take it each day?" [2]
• If the candidate reaches for a dose increase, challenge gently: "Wouldn't it be simpler just to put the dose up?" — the strong candidate explains why that is the trap. [2]
• If the candidate blames the family, the actor should respond defensively to surface the rapport problem for the marking scheme. [1]
• If the candidate names a formulation but does not involve the pharmacist, ask: "Who would you work with to actually get a different formulation?" [9]
