Health Promotion, Patient Education, and Evidence-Based Practice
Prevention happens in the emergency department
Every encounter is a chance to screen and intervene: tobacco and alcohol use (SBIRT), HIV and hepatitis C testing where indicated, intimate partner violence, depression (PHQ-2/9), fall risk, vaccine status including tetanus, influenza, and pneumococcal, and STI screening. Brief motivational interviewing outperforms a lecture, and a warm handoff referral closes the loop.
Education that actually lands
Use plain language, limit the message to two or three key points, confirm with teach-back ("tell me how you'll take this"), and provide written or pictorial reinforcement at an appropriate reading level. Include return precautions, medication reconciliation, and follow-up logistics, which are where most discharge failures occur.
Evidence-based practice
Frame a PICO question, identify the level of evidence (systematic reviews and randomized trials above cohort and case series), appraise for bias and applicability, and translate the result into a protocol that fits your population. Guidelines and protocols are not identical: a protocol operationalizes evidence for your setting. Distinguish patient-oriented outcomes from surrogate endpoints, and remember that a statistically significant result may not be clinically meaningful.
Traps
Quoting a single study as settled fact; confusing a guideline recommendation with a regulatory requirement; relying on an unappraised search result; providing education without confirming understanding; assuming a surrogate endpoint predicts what patients actually feel or survive.
Rule of thumb
Teach-back plus a written return-precaution plan is the cheapest discharge intervention with strong evidence: if the patient cannot repeat the plan back, the plan is not yet in place.
