Yesterday I helped a new MBA student who is in the joint program about health care administration. They have an assignment in which she was to find information to support the position that the closure of hospitals does not impact the quality of patient care. (She said she didn't believe this, but it was the position she was assigned.) I showed her how to use Bearcat, which resulted in some articles (I limited the search to health resources and the year 2007 for the example.) She said it didn't matter what type of hospital (other than being in the U.S.) Using NBER, Health Reference, Medline, and ABI inform, we found some articles and studies. Health Reference has the subject heading hospital closures. A number of the articles dealt with the closure of specific types of hospitals--for example public hospitals for the mentally ill. SSRN had some articles about closures of hospitals in other countries.
The student is currently employed as a physician's assistant at a NYC hospital.
