EBIR common mistakes
EBIR · Understand the traps and how to avoid them.
Answering indication questions by naming the procedure the candidate personally performs, rather than justifying the choice against the guideline-defined alternatives and their contraindications.
Candidates train in a single centre with a strong local preference (for example, always embolising where surgery or conservative management is guideline-endorsed) and unconsciously treat local habit as the reference standard. EBIR questions test decision-making across the whole pathway, including when not to intervene.
What to do instead
For every procedure, rehearse a three-line justification: indication class, first-line alternative, and the specific contraindication that would push you to the next option. Practise answering 'why this and not that' aloud for the ten procedures you perform most, citing the decision rule rather than your unit's practice.
Confusing the reporting vocabulary of complications: mixing up the SIR classification categories, or describing a complication without grading it or stating the required management tier.
Complication grading is learned informally on the ward and the categories blur under exam pressure, especially the boundary between minor treatment and major therapy categories and the threshold for permanent sequelae or death.
What to do instead
Build a one-page table of the SIR complication categories with a worked example for each, including the therapy escalation and sequelae axis. When practising, always finish a complication answer with the category and the management step, never just the description.
Describing a technique in narrative order without stating the access route, needle or catheter sizes, and the endpoint that defines technical success.
Experienced operators automate these details and omit them when writing, while examiners mark the technical parameters and success criteria explicitly. The candidate knows the steps but does not surface the numbers.
What to do instead
Write each core procedure as a structured checklist: access, equipment calibre, key manoeuvre, endpoint, and post-procedure care. Time yourself producing the numbers from memory, then verify against a current textbook chapter and correct the gaps.
Treating imaging interpretation as pattern recognition and giving a diagnosis without the imaging sign, its location, and the differential that the finding excludes.
On a workstation the candidate scrolls, correlates with history, and reaches a conclusion quickly; in the exam the reasoning chain must be written out. Candidates assume the diagnosis alone earns the mark.
What to do instead
Practise a fixed reporting sentence: finding, location, characterising sign, most likely diagnosis, and the main differential with the feature that separates it. Apply it to twenty anonymised cases and check that every sentence contains a sign, not just a label.
Confusing pre-procedural coagulation and medication thresholds, quoting a single INR or platelet number without the procedure-specific threshold or the bridging rule for anticoagulants.
Thresholds differ by procedure risk and by agent, and many candidates memorise one number from a single rotation. Guidelines also distinguish prophylactic from therapeutic anticoagulation, which is easy to collapse into one rule.
What to do instead
Construct a matrix of procedure bleeding risk against agent, with the stop, bridge, and restart timings in each cell. Learn the reasoning behind the thresholds so that an unfamiliar scenario can be answered from principle rather than a memorised figure.
Answering radiation-protection questions with general ALARA slogans instead of the specific dose metric, the typical dose range for the procedure, and the deterministic versus stochastic risk distinction.
Protection is taught as culture rather than as numbers, so candidates can recite principles but cannot state reference levels, threshold doses for skin injury, or which dose quantity applies to which risk.
What to do instead
Memorise a short table: procedure, typical dose-area product or air-kerma range, and the corresponding skin-dose concern. Pair each deterministic effect with its threshold and each stochastic risk with its dose dependence, then test yourself on unfamiliar combinations.
Giving a single management answer for a clinical scenario without stratifying by patient stability, comorbidity, or the urgency that changes the pathway.
Case-based items look like single-best-answer questions, but the discriminating step is often the branch point. Candidates anchor on the first plausible option and stop reasoning once they find something defensible.
What to do instead
For each scenario, explicitly write the branch point before choosing: stable versus unstable, infected versus sterile, salvageable organ versus not. Then give the answer for each branch. Practise on ten stem-style vignettes and mark whether you identified the branch.
Mixing up the vascular and non-vascular anatomy that shares a name or a territory, such as the arterial supply variants relevant to embolisation or the segmental anatomy relevant to ablation and drainage.
Anatomy is revised as lists of names rather than as three-dimensional relationships, and variant anatomy is under-learned because routine cases rarely show it. Exam items deliberately probe the variant.
What to do instead
Redraw the relevant territory from memory, including the common variants and their frequency, then check against an atlas. Link each variant to the procedural consequence, such as a non-target embolisation risk or an altered access route.
Writing oncological answers that name the technique but omit the patient-selection criteria, the expected outcome measure, and the position of the treatment relative to surgery and systemic therapy.
Interventional oncology is often learned procedure-first, and outcome data are remembered vaguely. Candidates describe how to ablate or embolise but cannot state who should be offered it or what survival or response endpoint is expected.
What to do instead
For each tumour type, build a short pathway: selection criteria, treatment options in order, the outcome measure for each, and the evidence level. Rehearse stating one number per option, such as a response rate or a median survival figure, with its source.
Ignoring the non-technical domains in the syllabus, answering only the procedural parts of a question and leaving out consent, communication, multidisciplinary team working, or service organisation.
Candidates concentrate revision on techniques and imaging because those feel examinable, and treat professional and organisational content as background reading. The curriculum, however, assesses these explicitly.
What to do instead
Map the syllabus sections against your revision plan and allocate explicit sessions to the non-procedural domains. For each, prepare concrete examples: how consent is documented for an urgent case, what the multidisciplinary meeting contributes, and how a service is audited.
