Assessment, Diagnosis and Investigations
Obtain and synthesise history, examination and investigations into defensible differential and definitive diagnoses.
How to prepare for ORE Part 1
Connect scientific knowledge to clinical decisions, then rehearse selecting the safest best answer or matching option under time pressure.
Core concepts
Concept 1
A complete assessment includes the patient's medical, dental, social and medicine history, expectations, anxiety, examination and proportionate investigations.
Exam cue: Ask what information would change the differential or immediate plan.
Concept 2
Diagnosis requires synthesis; no single finding should be used outside the whole clinical picture.
Exam cue: Choose investigations only when their result can influence management.
Risk pitfalls and guardrails
Ordering a test routinely without a clinical question.
Guardrail: Do not choose a technically possible answer that ignores urgency, consent, competence, medical risk, follow-up or patient priorities.
Anchoring on the first plausible diagnosis and failing to reconcile conflicting evidence.
Guardrail: Do not choose a technically possible answer that ignores urgency, consent, competence, medical risk, follow-up or patient priorities.
Memory anchors
What belongs in comprehensive assessment?
History, examination, anxiety and expectations, risk, medicines and justified investigations.
What makes an investigation appropriate?
It is justified, proportionate and likely to change diagnosis or management.
What is a differential diagnosis?
A ranked set of plausible explanations that guides further discrimination.
When does a diagnosis become definitive?
When the available evidence supports it sufficiently for the required decision.
How is anchoring avoided?
Actively test alternatives and reconcile findings that do not fit.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
