Use of the Mental Health Act Criteria in the Decision-Making Process for Compulsory Admissions: A Study of Psychiatrists in South London

Abstract

This study investigates the decision-making process for admitting patients compulsorily under the Mental Health Act 1983 of England and Wales. We used three case-vignettes describing different clinical situations: 1) a man with depression and psychotic symptoms; 2) a woman with a possible first episode of psychosis; and 3) a man with a history of substance abuse and bipolar disorder. The vignettes were administered to a group of psychiatrists working at the Bethlem Royal and Maudsley Hospitals in South London.

The psychiatrists were asked to rate 11 factors from the most to the least important in their decision to admit the individual compulsorily. Three factors resembled the criteria considered in the Mental Health Act 1983 for compulsory admission: current mental state; severity of the disease; and dangerousness to self or others. Three were other clinical features of the patient: diagnosis; psychiatric history; and likely response of the mental state to the medical treatment. The remaining five were sociodemographic features of the patient: age and gender; owning a home; occupational status; and social support available. The psychiatrists were not given the option that the patient would accept a voluntary admission to hospital. We obtained responses from 42 psychiatrists (25 males and 17 females). The most important factor for deciding to detain a patient compulsorily was perceived dangerousness to self and others. The current mental state of the patient and the severity of the illness were the next two important factors. Our results confirm that the criteria recommended by the Mental Health Act 1983 of England and Wales were applied consistently in three different hypothetical situations. The need for protection of the patient or others may take precedence over the current mental state of the patient or the severity of the illness, a finding that warrants further investigation in view of the current debate on the responsibility of psychiatrists in deciding to detain subjects affected by personality disorder.
