[What information do patients with schizophrenia have about their illness and treatment?].

Improved compliance with antipsychotic medication is a major issue in schizophrenic management. For this purpose educational programs have been used, but up to now, little or no information has been gathered or published in France concerning schizophrenic patients' opinion on information they have about their disease and their treatment. Thus we conducted a survey in concert with 78 psychiatrists from the French psychiatric health service. From this cross sectional survey we assessed 336 outpatients (male: 72%; mean age: 36 +/- 10.4 years) with schizophrenia according to the DSM IV (paranoid sub type: 57%, disorganized: 12%, catatonic: 1%, undifferentiated: 12%, residual: 18%). The mean duration of the illness was 11.6 years (sd: 8.5) and the mean duration of the follow up with the same psychiatrist was 5.4 years (sd: 5.1). Patients completed a questionnaire which assessed their level of information on mental illness and treatment. The diagnosis of schizophrenia has been told to their patients by 39% of the psychiatrists, and treatment has been explained to the patients by 96% of the practitioners. Results indicate less than half of the patients (45%) felt ill, only 46% thought they knew their illness well or very well (nevertheless only 31% of them named spontaneously the diagnosis of schizophrenia or psychosis), and 61% considered that they had been given sufficient information. Most of the patients (79%) were persuaded that their treatment was useful, and 75% of patient were completely satisfied with their treatment. Surprisingly 92% reported taking their medication regularly. Most patients think that a high level of information about their illness (74%) and treatment (79%) help them to cope better with their schizophrenia. Analysis performed according to patients characteristics indicated that paranoid patients felt more ill (p = 0.035) than others, thought to know less about their illness (p = 0.0065), and were less satisfied with their treatment (p = 0.04) and their level of information (p = 0.03). Patients with a duration of their illness longer than 10 years were more convinced of the utility of their treatment (p = 0.02) and had debated more on the choice of their treatment with their psychiatrist (p = 0.047). Patients older than 35 years were more satisfied with their information (p = 0.002). More patients with atypical antipsychotics accepted to take their treatment on a regular basis (p = 0.035) compared to patients under classical neuroleptics. This survey underlines that mental health consumers' opinions can be obtained even in the field of schizophrenia, and argues in favour of further such investigations. It also highlights the need for educational programs on schizophrenia and antipsychotic medications.
