Homeless mentally ill patients in the community: results of a general hospital emergency room study.

Previous inattention to the specific circumstances of homeless mentally ill individuals in general hospital settings is discussed. Homeless mentally ill individuals who presented for emergency psychiatric care in a public general hospital setting exhibited distinctive patterns of service utilization and showed evidence of being a uniquely disabled, rootless, and impoverished subgroup of mentally ill individuals. The characteristics of homeless users of general hospital psychiatric services may provide some important clues to system-wide deficits in community-based care for the members of this population.
