After applying what you've learned from the literature to your situation, you will need to evaluate outcomes in shorter-term and longer-term intervals. In assessing the situation, you regard feedback from all staff and from patients. You notice changes and statistics of patient care and outcomes, as mentioned in the articles. You personally will need to decide after what period of positive or negative feedback you decide to consider the changes a success or choose alternative plans.
You should not only assess the outcomes in your situation, but also the effectiveness and efficiency of the evidence based process and consider avenues for improvement.
