Evidence-based practice

Why this matters

A paper is not a plan. A guideline is not a person. Evidence-based practice is the skill of asking a usable question, finding relevant evidence, judging it, and applying it here.

The core model

Best available evidence + clinical expertise + patient values and circumstances + local context.

Drop any one of those and the decision becomes either cookbook or anecdote.

Workflow

1. Ask — turn uncertainty into a focused question. PICO where it helps: Patient/problem, Intervention, Comparison, Outcome.
2. Acquire — find relevant evidence.
3. Appraise — validity, bias, methods, sample, effect size, confidence, relevance, limitations.
4. Apply — does this person resemble the studied population? Are benefits clinically meaningful? What are the risks? What does the person value? Is the intervention available here?
5. Assess — what happened, and what will you change?

Does evidence travel?

Evidence generated in one population or health system may not transfer directly to another. That is Elaryvo’s principle: globally informed, locally grounded.

1. Is the disease burden similar?
2. Are resources comparable?
3. Are baseline risks similar?
4. Is follow-up feasible?
5. Are treatment alternatives available?
6. Does cost matter in this setting?
7. Are cultural or health-system differences important?

Common pitfalls

Quoting a paper you have not appraised.

Treating absence of local evidence as absence of a decision.

Ignoring the person’s values because the trial was positive.
