This audit examined 65 consecutive admissions to a psychiatric hospital in the Irish Midlands over six months. The admissions came from a defined sector with a total population of 39,000. In the year prior to the study major changes in the delivery of psychiatric care in the sector were instituted. These changes included the introduction of admission guidelines and extra resources in the community. The general practitioners who see mental illness at first contact were informed of these changes. Attempts were made by the sector psychiatrist team to screen for appropriateness of admission with regard to the special groups such as alcoholics, the aged and the mentally handicapped.
