The use of seclusion: a comparison of two psychiatric intensive care units

The use of seclusion within a psychiatric intensive care unit in a South Australian metropolitan mental hospital was documented over a ten week period. The seclusion rate within the unit was 32% of all admissions and 34% of new admissions. The overall seclusion rate for the hospital was 5.4% of all admissions and 6.3% of new admissions, somewhat higher than in the United Kingdom but considerably lower than in the Eastern United States. A comparison was then made between consecutive new admissions (30 secluded and 30 non-secluded) to this unit and to a similar unit without a seclusion room in the other mental hospital in the State. Although seclusion offered no clear advantages in terms of duration of admission, levels of medication or relapse rates, it appeared to reduce the level of dangerousness in the unit, thereby enhancing staff morale. The overall mean daily total of neuroleptic medication was about 1,200 mg chlorpromazine equivalent, somewhat less than in comparable units in the United States and Europe.
