Point of care tools are designed to be used by healthcare providers at, well, the point of care. This means that the information will be succinct and not in a typical article format. These are great places to start your research, as they provide a nice overview without making you wade through tons of articles.
Textbooks also offer useful overview information without getting into too many specific details, or overwhelming you with research methodology. You don't even need to visit the library in person, as many of these books are fully accessible online.
Review articles normally give you a nice overview of a topic, which can be a very useful thing!
