Abstract
The multi-hospital arrangements literature is reviewed for Canada and the United States. There is a notable lack of evaluations on the outcomes of these arrangements, especially in the Canadian context. For evaluations that do make it to the literature, generalizability of conclusions is difficult because most is based on case studies and relates to “for-profit” U.S. hospitals. We are forced to conclude, however, that there is little definitive evidence that quality of care is improved by multi-hospital arrangements or to support or refute the claims of better human resources deployment. The most striking organizational benefit appears to be that institutions considering merger or other arrangements are forced into explicit considerations of their mission and goals. Many of the potential disadvantages of multi-hospital arrangements may be ameliorated with appropriate strategic planning and attention to detail during negotiation of the arrangement. As new multi-institutional arrangements may cause harm as well as reap benefits, careful evaluation is needed.
