I am having trouble identifying my two research articles for Evidence Based Practice. They have to be less than five years old, a single study, peer reviewed. One needs to be a qualitative research study ad the other needs to be a quantitative research study. My subject is will rounding on patients in an acute hospital decrease falls. The only articles I have been able to identify are non-research quality improvement or process articles. I just don't seem to understand. I have been working on this for 5 days straight. The more I read the articles the more I dout myself. Please help me find my two articles.
