Objective.-To examine the impact of alcohol and substance use on the early course of psychosis. Methods: First-admitted, subjects with psychosis (n = 58) were assessed at 6-month intervals over a 2-year follow-up. Information on substance and alcohol misuse and clinical and social outcome was collected using multiple sources of information. Results.-After adjustment for potential confounding factors, subjects with persistent substance misuse over the follow-up were at increased risk of readmission (OR = 3.1; 95%CI = 1.0-9.4; P = 0.05), of presenting with psychotic symptoms (OR = 4.3; 95%CI = 1.0-18.1; P = 0.04), and with a non-continuous course of illness (OR = 11; 95%CI = 1-122; P = 0.05). No significant association was found between substance misuse and social outcome, or between alcohol misuse and clinical and social outcome. Conclusion.-Persistent substance misuse after a first admission for psychosis has a deleterious impact on clinical outcome. Early identification and treatment of substance use is essential in the care of subjects with incipient psychosis. (C) 2003 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
