Evidence, Technology and Referral Pathways
Use evidence, evaluate new technology and navigate specialist, dental and wider-healthcare referral systems.
How to prepare for LDS Part 1
Build clinically applied knowledge, then practise selecting the single best safe action from five plausible options under timed conditions.
Core concepts
Concept 1
Evidence-based practice integrates the best available evidence with clinical expertise, patient values and the clinical context.
Exam cue: Appraise relevance and quality before applying evidence to a different patient or setting.
Concept 2
A referral must communicate urgency, purpose and relevant findings through an appropriate pathway while responsibility is handed over safely.
Exam cue: State why, where and how urgently the patient should be referred, then ensure follow-up.
Risk pitfalls and guardrails
Equating novelty or publication with clinically useful evidence.
Guardrail: Do not select a technically possible option if it ignores urgency, consent, medical risk, competence, follow-up or the patient's priorities.
Making a referral without supplying essential information or arranging interim safety.
Guardrail: State the reason and urgency, protect the patient while transfer is pending, and close the communication loop.
Memory anchors
What four elements make practice evidence-based?
Evidence quality, clinical expertise, patient values and clinical context.
How should new technology be judged?
Benefit, harm, evidence, usability, equity, cost, governance and fit with practice.
What makes a referral complete?
Reason, urgency, relevant findings, actions already taken and a clear receiving route.
What are access-point responsibilities?
Recognise wider-health needs, signpost or refer appropriately and communicate across services.
Who retains responsibility during referral?
The referring clinician retains appropriate responsibility until safe transfer and follow-up are established.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
