Professional Practice, Research, Teaching, and Administration
Evidence and professional practice
Use evidence-based practice: formulate a focused question, search efficiently, appraise validity, and apply findings to the patient. PICO-population, intervention, comparison, outcome-sharpens clinical questions. Know basic designs: randomized trials for causation, cohort studies for prognosis, case-control studies for rare exposures, and diagnostic studies for test accuracy. Distinguish statistical significance from clinical importance; a small effect can be significant in a large sample.
Appraise validity, reliability, sensitivity, specificity, and confidence intervals. Check whether the study population resembles your patient and whether outcomes matter. Guidelines are tools, not substitutes for judgment.
Teaching and administration
Effective teaching sets objectives, uses active learning, gives specific feedback, and assesses competence. Supervision must match the learner's level and the patient's risk. Documentation should be timely, accurate, and defensible. Know scope of practice, consent, privacy, and billing rules. Quality improvement uses repeated cycles-plan, do, study, act-rather than one-time audits.
Worked example. A colleague presents a single small trial showing improvement. Before changing practice, check randomization, blinding, baseline similarity, effect size, confidence intervals, and applicability. Rule of thumb: ask whether the evidence applies to this patient, this setting, and this outcome. Evidence informs practice; it does not replace clinical reasoning.
