Evidence-based practice is not a search for one article that tells the nurse what to do. In Canadian nursing, evidence-informed decision-making means using the best available evidence, critically appraising it, and then integrating it with clinical judgment, the client’s circumstances, and the client’s goals. Each part prevents a different error. Research can identify interventions that tend to produce better outcomes across groups. Clinical judgment identifies whether the study population, setting, and intervention resemble the person in front of the nurse. The client identifies what outcomes are acceptable, realistic, or most important. A plan is not evidence-informed if any one of these is missing. A client may decline an otherwise supported treatment because of a previous adverse experience, cultural belief, financial barrier, or competing goal. That preference does not make the research wrong; it changes whether the intervention is appropriate for this client at this time. Conversely, client preference does not require the nurse to provide an unsafe or ineffective option. The nurse explains options honestly, explores concerns, and collaborates on the safest feasible plan. Evidence also differs from local data....
