title: Having a usual source of care reduces ED visits.
abstract: The recent growth in the use of emergency departments (EDs) is costly, undesirable, and unnecessary. This trend is partly due to a growing proportion of persons who lack a usual source of care. This group is increasingly likely to rely on EDs for their health care needs compared with those who have a usual source of care.
