title: Self-sufficiency in a regional hospital system.
abstract: This article considers measures that indicate the degree of regionalization within a hospital system. In particular, regional independence is characterized with a "self-sufficiency" index. The basis of these measures is the use of facilities in one region by residents of another region, that is, interregional flows. Examples of the use of the suggested measure in the Nova Scotia hospital system are presented.
