This is the second of two articles on GP referrals for compulsory admission, and seeks to examine the process and outcome of assessment by (a) comparing GP with other section assessment referrals and (b) comparing GP referrals who were compulsorily admitted to hospital with those not compulsorily admitted or voluntarily admitted. In relation to the law the main relevant sections for this article are sections 2, 3 and 4. There are two basic grounds for admission: that the patient is suffering from a mental disorder and that admission is in the interests of his/her own health or safety or for the protection of others. Section 4 requires one and sections 2 and 3, two medical recommendations, as well as an application by an approved social worker (ASW) or nearest relative. Section 2, admission for assessment, involves admission for up to 28 days; section 4, emergency admission for assessment, involves admission for up to 72 hours; and section 3, admission for treatment, allows admission for up to six months, and is renewable.
