Evidence Based Practice

An NP may need to decide whether a new intervention is worth its burden for one patient, or whether a familiar unit practice should change after outcomes begin to deteriorate. Neither question is answered safely by a quick literature search, a single persuasive study, or the phrase we have always done it this way. The safety problem is not a lack of information. It is using information without judging its trustworthiness, relevance, or fit. Canadian nurses use evidence-informed decision-making: they critically appraise sources such as systematic reviews, primary research studies, and peer-reviewed journals before integrating findings into practice [1]. Evidence does not replace clinical expertise or patient values. It makes the reasoning behind a decision more transparent and allows the NP to weigh benefits, harms, feasibility, and the patient’s goals. This process applies beyond an individual prescription. An NP who leads practice change must help the team ask a useful question, examine the evidence, test the proposed change, and learn from its results. That work depends on leadership behaviours and organizational conditions, not on literature appraisal alone.
