Q. I am writing a research paper on HIV and I'm having trouble finding articles on the stages of HIV and the clinical presentation of these stages.
I had used the CDC for some of the information and my professor replied asking me to use 'provider level' sources. If I were to guess, I would assume she meant primary sources.
I'm not familiar with the phrase "provider level source" and I don't find that it's been used in the medical literature. It's common for projects to require that research draw on "primary sources." Could that be what you need? If not, please let me know what you mean by "provider level source."
I recommend seeking out primary source articles and then, if possible, emphasize for your research those originating with practitioners - e.g., doctors, hospitals, pharmacists, hospices, etc. Such sources may offer a different perspective than the CDC and academic researchers. If that proves to be too limiting, then I'd suggest confirming with your professor the limits that she has in mind.
One of my colleagues suggested that you might look for review articles in CINAHL (the index to nursing and allied health literature) or in the journal American Family Physician. These sources might lead you to the kind of research you hope to find.
I tried searching "HIN symptoms progress" in PubMed to get an idea of the types of responses that would result. It's a heavy-handed approach that gets all kinds of responses, but some of them seem to deal with the presentation stages of the disease. You might review some to the citations that result from such a search and then see what subject terms are used to characterize the ones that seem particularly relevant. Again, review articles (you can limit searches to review articles) may give you a good window to the research, and you may want to perform similar searches in CINAHL and the AFP journal.
Also, we have online access to a number of medical reference books and textbooks, and they may give you additional insights.
