[The study of the impact of the consensus conference "Strategies for long-term therapy of patients with schizophrenia"].
The case management, treatment and psychosocial rehabilitation of schizophrenic patients is an important part of the activity of the psychiatric sector and takes up many human, scientific, organizational and financial resources. The best way to reach satisfactory results for the individual patient is still uncertain and current practice in France shows noticeable variations that have been rarely investigated in terms of outcome. A consensus conference (CC) on "Strategies for long-term therapy of patients with schizophrenia" was therefore held in Paris in 1994 to produce accurate guidelines designed to help both clinicians and patients and to improve practice. It was organized by the French Federation of Psychiatry, the National Union of Friends and Relatives of Mental Patients, and the National Agency for the Development of Health Evaluation. The conclusions of the CC were mailed, in the form of a booklet, to members of these associations (psychiatrists and relatives) and were reported in the medical and general press.


METHODS
The impact of the CC was judged by (a) the psychiatrists'awareness of the existence of the CC, (b) their knowledge of its conclusions, and (c) changes in practice. The following were analyzed: press coverage; requests for the booklet; the results of a survey of a representative sample of 396 psychiatrists two years after the CC; prescription changes in the public sector in a cohort of 2,407 schizophrenic patients under treatment at the time of the CC; prescriptions to psychotic patients by a representative sample of psychiatrists in private practice.


RESULTS
Awareness: Articles on the CC were published in 27 journals and newspapers, 30,000 booklets were distributed and 8,348 were mailed in response to 1,121 spontaneous requests; 78% of the psychiatrists interviewed said they were aware of the existence of the CC and 70% said they were aware of the conclusions. Knowledge: The psychiatrists' declared practice conformed with CC conclusions 41%-85% of the time depending on the recommendation. No difference in practice was noted between the psychiatrists who said they knew of the recommendations and those who said they did not. Changes in practice: A significant but small improvement in prescription habits was noted for a principal recommendation ("just one neuroleptic is enough"). One-neuroleptic prescriptions increased from 51.1% the year before the CC to 56.4% two years after the CC. The increase mainly concerned the most recently treated patients. However, during the same time-span, prescriptions of anti-cholinergics plus neuroleptics rose from 48.2% to 54.3%.


CONCLUSIONS
It is difficult to attribute changes in practice to a CC. However, the impact of the CC seemed real even if inconstant and not great enough. Clearly, to enhance impact an action plan is needed. It should include corrective measures and focus on additional dissemination efforts, teaching and training programs, and updating of guidelines if necessary.
