Of the CMHT sample, three-quarters (n1⁄4216) had a psychotic disorder and 41 had a primary diagnosis of severe depres- sion. Additional ‘complex care needs’, which tend to qualify patients for enhanced CPA management, were present in 80% (n1⁄4226): these were previous psychiatric admission, suicidal behaviour, self-neglect/ harm, risk of exploitation or secondary psychiatric disorder. Most of the drug service patients reported lifetime opiate use (92.6%, n1⁄4200), and 78% (n1⁄4158) reported lifetime injected drug use. Some alcohol service patients reported controlled drinking in the past year, but 79% (n1⁄449) recorded AUDIT scores indicative of severe alcohol misuse.
