In both the GW and Consortium catalogue and Worldcat, it may prove most useful to search for a combination of subject headings. One can do this by searching Worldcat and also by selecting the GW and Consortium catalogue then clicking on the search button and then on advanced search. Here are some examples:
health insurance and compliance
medical and compliance
medical and confidentiality
health and confidentiality
medical and privacy
health and privacy
In addition, searching for a particular relevant act or regulation might prove fruitful, for example:
health insurance portability and accountability act
