Advantages of Further Nursing Education

Hello all! I am working on my Master's Degree and we are working on a project regarding the Institute of Medicines Future of Nursing Report, specifically in regards to nursing education. I am wondering if anyone knows of any studies or anything scientifically specific that shows advantages / disadvantages of having BSN or further education. I know many people feel very strongly about the ADN vs BSN argument and do not really want to go there. I am just looking for specific studies (such as Linda Aikens study on Surgical Patients) that show if there is a correlation in outcomes in regards to the nurses education. Any assistance would be greatly appreciated. Thank You.
