This is a lot easier than you are making it out to be. Try taking the words evidence based out of the question and say to yourself, "I am writing a paper about diabetes." Then ask yourself, what do we 'know' about diabetes, WHY do we treat diabetic patients the way we do, what might happen if diabetics are non-compliant and how would we approach (treat), those patients? Then ask yourself, how come we DO treat these patients the way we treat them, the answer to all these question is based on research. Research found that, based on this study, that study, etc., that the BEST way to treat diabetes, and diabetics, is WHAT? and WHY? You use the articles you read, which are in scientific journals, from studies you looked at, etc., and this is the 'research' you cite in your paper as the 'evidence' to how we approach diabetes, and diabetics the way we currently do. Just make sure to write your paper in the format required, usually AMA, and you will be done. Writing papers like this broadens your understanding of diseases, processes, and the current thoughts in the medical field that keep you current and updated. You will be amazed at what you will learn. Good luck, and don't stress it.
