NAC OSCE common mistakes
NAC OSCE · Understand the traps and how to avoid them.
Starts the station by asking a long list of closed yes/no questions about symptoms before greeting the patient, confirming identity, or establishing what the patient is worried about.
Under time pressure candidates default to a biomedical checklist and fear that open-ended questions will 'waste' the first minutes, so rapport and agenda-setting get skipped.
What to do instead
Use a fixed 30-second opening script every time: greet, confirm name and what they like to be called, state your role, ask 'What brings you in today?' and 'What were you hoping we would cover?', then signpost before narrowing. Rehearse the script until it is automatic so time pressure cannot erode it.
Interrupts the patient's opening statement within the first few seconds and never returns to the full list of concerns.
Discomfort with silence and the belief that the clock is already running makes candidates jump in early, and once they take the floor they never hand it back.
What to do instead
Practise a deliberate silent count to ten after the opening question, then use a summary statement ('So there are three things: the cough, the sleep, and the medication question') before moving on. Have a practice partner time how long you allow before the first interruption and drive it past 30 seconds.
Performs a physical examination manoeuvre without explaining it, without positioning or draping the patient, and without asking permission before touching.
Attention is consumed by getting the technique right and finishing within the station time, so communication and consent during the exam are treated as optional extras.
What to do instead
Attach a verbal step to every physical step: explain what you are about to do and why, ask permission, warn before any uncomfortable manoeuvre, and narrate findings neutrally. Build this into your practice so each hand movement has a paired sentence, and always verbalise draping and privacy even when the examiner is the patient.
Generates a broad differential but never commits to a leading diagnosis, never states the most dangerous diagnosis to exclude, and never links investigation or treatment choices back to either.
Candidates fear being wrong and hedge by listing possibilities, which feels safe but reads as indecision and disorganised clinical reasoning.
What to do instead
Close the assessment with a structured one-liner: most likely diagnosis, key supporting features, top can't-miss alternative, and the single test or action that separates them. Practise this synthesis aloud in every practice station so prioritisation becomes a habit rather than an afterthought.
Gives a management plan that is a list of tests and referrals without stating which is urgent, what the patient should do while waiting, and what would prompt them to seek emergency care.
Candidates equate a complete answer with a long answer and omit safety-netting because it does not feel like 'medical content'.
What to do instead
Use a fixed management scaffold: immediate action, investigations with timing, treatment with dose and duration where relevant, referral with urgency, follow-up interval, and explicit safety-net instructions in plain language. Say the safety-net sentence out loud even if it feels obvious.
In a breaking-bad-news or conflict station, delivers the information in one uninterrupted monologue and does not pause, check understanding, or respond to the patient's emotional cue.
Anxiety about the difficult conversation drives candidates to offload information quickly, and unpractised silence feels like failure.
What to do instead
Use a warning shot, then deliver in small chunks, then stop and name the emotion you observe ('You look shocked'). Count three seconds of silence after each chunk before continuing, and rehearse at least one empathic response to each of anger, tears, and denial.
Talks about the patient to the examiner or team in front of the patient during a station, using jargon and referring to them in the third person.
Candidates mentally split the 'examiner' and 'patient' roles and treat the examiner as the real audience whose approval matters.
What to do instead
Treat the patient as the sole audience and the examiner as an observer. If a handover is required, say explicitly 'I'd like to summarise your case to my colleague, is that alright?' and keep the patient addressed. Record yourself and count any third-person references to the patient.
Does not ask about the patient's ideas, concerns, expectations, or social context, and therefore misses the reason for the visit and the barriers to the plan.
The biomedical model dominates preparation, and ICE questions feel repetitive or 'soft' compared with symptom history.
What to do instead
Make ICE a non-negotiable block immediately after the opening statement, and add one social-context question (work, caring responsibilities, cost, transport, language) to every station. Write ICE and context on your practice notes as fixed headings so omitting them is visible.
Ignores system-level factors such as cost, access, wait times, or social determinants when the case clearly involves them, offering only ideal-world medicine.
Candidates study management as guideline-driven and rarely practise adapting it to resource constraints or inequity.
What to do instead
In every management plan, add one sentence on feasibility: what is covered, what it costs, what the waiting time is, and what alternative exists if the patient cannot access the first-line option. Practise naming one health-advocacy angle per station, such as transport, housing, or food security.
Fails to close the station: no summary, no invitation for questions, no explicit statement of what happens next and when, and no thank-you or goodbye.
Time pressure or relief at finishing the clinical content causes candidates to trail off, leaving the encounter feeling unfinished to the examiner and the patient.
What to do instead
Memorise a closing script: summarise the plan, ask 'What questions do you have?', state exactly what happens next and when, confirm the patient agrees, offer written or interpreter support if needed, and thank them. Practise ending every station with the same five sentences until the timing is automatic.
