Try out the Cambridge Handbook of Communication Disorders for your topic. It has 2014 (publication year) reviews on a wide range of CSD topics. We have the ebook, plus one in Reference Stacks (1st floor) and one to check out ( RC423 .C24 2014, 3rd floor).
Often when I start on a topic in the health sciences, I am not familiar with treatments and outcomes. (You might be much more familiar if you're practicing or in a practicum.) I start by searching for reviews and primary articles on the problem. The abstracts should include treatments and outcomes. Once you identify some of the outcomes that make sense for your topic, you can go back and include those in your search. Studies that focus on important outcomes will be more useful to you.
