Problem:
Focus on refining one of your PICOT topic is the opioid global epidemic and the elevated incidence of opioid misuse and dependency among patients receiving treatment for chronic pain.. Search various data bases and identify the data base you believe would be most appropriate to obtain information about your question (see Chap 3 and tables 3.1 and 3.2) and provide the rationale for your selection. Create a hierarchy of the level of evidence that would be helpful in obtaining a response to your question (see Chap 2 and table 2.4). (There are two steps here-listing the appropriate databases and identifying appropriate levels of evidence.)
