I agree with the above poster. It's highly unlikely that anyone has written the types of reviews you seek on that specific question.
A common mistake beginners make when working with evidence-based practice, research, etc. is that they try to start with a "final" question and then hope that someone "out there" has written exactly what they need to go forward as they hope. Experienced people take a different approach. They start with a general topic of interest ... then go to the literature to discover what has already been written on that topic. They use that literature review to refine their basic question so that their final question/project is feasible given the literature resources that are available.
Some Evidence Based Practice models include this step. They refer to "background questions" vs "foreground questions." Your background question would be something like ... "What type of discharge preparation helps to prevent readmission?" As you explore the literature on that general topic, you can then refine your question to the classic foreground question in the PICO format of your assignment, comparing 2 types of discharge preparation and their effects on readmission.
That basic process works for a wide variety of student and professional projects.
1. Start with general topic
2. Review literature
3. Identify other necessary resources
4. Refine topic so that the project is feasible with available resources
