[Clinical and socio-demographic profile of patients with schizophrenia according to the antipsychotic treatment prescribed]. / Analyse du profil socio-démographique et clinique de patients schizophrènes en fonction du traitement neuroleptique reçu.

INTRODUCTION: Data concerning the characteristics of patients with schizophrenia and their treatment in day hospitals are scarce. Guidelines for clinical practice are, however, regularly published. Recommendations from the 1994 Consensus Conference underline the necessity of antipsychotic monotherapy in the long term treatment of schizophrenia. In the US the Schizophrenia Patient Outcome Research Team (PORT) published in 1999 treatment recommendations concerning the use of antipsychotics in the acute phase and in maintenance. For maintenance, the recommended dose should be between 300 and 600 mg/day (CPZ equivalents) (recommendation n 4). AIM OF THE STUDY: The aim of this study is to establish the socio-demographic and clinical profile of patients according to the dose of antipsychotic medication prescribed. The study also examines the use of antipsychotic polypharmacy. DESIGN: of the study. For this study, 116 patients treated in 12 different day hospital units were recruited. Inclusion criteria were: a DSM IV diagnosis of schizophrenia, being treated in a day hospital and having received antipsychotic medication for at last 2 months. Instruments were the MINI for a standardized diagnosis of schizophrenia, the CGI and the PANSS. Prescribed doses were transformed in chlorpromazine (CPZ) equivalents, in order to establish comparisons between patients. RESULTS: The population sample was composed of 72 male (61.5%) and 44 female (38.5%) patients. The mean age was 36.4 years old. The mean education level was 11.3 years. A large majority (n=103, 88%) of patients was celibate, 65 patients (55.6%) lived on their own, the others lived with their family (45 patients, 38.5%) or with a spouse (7 patients, 6%). A large majority of patients (75.6%) received some form of state allowance. Only 1.7% were receiving a salary. The mean antipsychotic dose was 660 mg/day and 68% of patients were treated with an atypical antipsychotic (amisulpride, clozapine, olanzapine, risperidone). Thirty-two percent of patients were treated with doses between 600 and 1,000 mg/day and 24% with doses above 1,000 mg/day. When comparing patients according to the dose level they were receiving (<300 mg/day; 300 to 599 mg/day; and 600 to 999 mg/day;>1,000 mg/day), there was no significant difference between groups for socio-demographic variables. Patients treated with doses below 300 mg/day had a better psychosocial profile and were more often treated with loxapine, haloperidol and risperidone. Patients treated with doses above 1,000 mg/day were more often receiving clozapine. There was still a substantial number of patients treated with conventional antipsychotics in the above 1,000 mg/day range. Patients receiving an antipsychotic monotherapy were more often treated with clozapine or olanzapine and presented a higher rate of positive symptoms. DISCUSSION: These results are discussed in comparison with present guidelines concerning the treatment of patients with schizophrenia.

[The subjective quality of life of patients with schizophrenia: influence of psychopathology and patients' expectations. A comparative study]. / Influence de la psychopathologie et des attentes sur la qualité de vie subjective des patients schizophrènes: une étude comparative.

Most studies on the quality of life (Qol) of patients with schizophrenia deal with objective living conditions and how they are perceived by hospitalized patients. The few studies that compare Qol for patients treated in part time services with the Qol of ambulatory patients do not show any significant difference in terms of subjective Qol. Some stu-dies evaluate the influence of psychopathology and needs (or expectations) on the subjective Qol in these groups of patients. Available data indicate that the general well-being is influenced by psychopathology (positive, negative or depressive symptoms) and unmet needs in ambulatory patients. They also show that subjective Qol in certain life domains (social relations, family relations, leisure, health, law and security) is influenced by negative symptoms, anxiety and depression in patients treated in part-time services. The aim of this study is to compare the objective and subjective Qol of patients with schizophrenia treated in part time services (day hospital and day care center) to the Qol of out-patients treated on a purely ambulatory basis (out patient clinic). We studied the Qol of 2 groups of 30 patients with schizophrenia (ICD 10 criteria) treated in various centers. The first group was made of ambulatory patients, the second one was constituted of patients treated in a day hospital or a day care center. Patients were matched for age, duration of illness, number of hospitalizations. The instruments used for rating were the following: Clinical Global Impression (CGI), Global Assessment of Functioning (GAF), Positive And Negative Symptoms Scale (PANSS), Drug Attitude Inventory (DAI-10). The Qol was measured with a french version of the Lancashire Quality Of Life Profile (LQOLP) (Salomé, Germain, Petitjean, Demant and Boyer, 2000). This instrument measures the objective Qol as well as the subjective Qol. It does possess satisfying psychometric properties and offers the possibility to establish Qol profiles. All Qol ratings were carried out by a clinician who was not involved in the treatment of the patients. When the 2 groups are compared our results indicate that ambulatory patients are less symptomatic, have a better level of functioning and a better objective Qol in such domains as: finances, living situation, family relations and health. There is no significant difference in terms of anxiety and depression as measured by the respective items of the PANSS. Patients treated in part-time services present higher scores of positive symptoms. Our results indicate that there is no significant difference for subjective Qol variables between the two groups, except for general well-being, that tends to be higher in ambulatory patients. When exploring the influence of clinical data on the Qol in each group, we find negative correlations in ambulatory patients between various domains of subjective Qol and illness severity (law and security, family relations, social relations, general well-being), global functioning (family relations, social relation, health) and positive symptoms (living conditions, law and security, family relations, social relations, health). In this same group, the subjective Qol for family relations is significantly correlated with several expectations in terms of Qol improvement (leisure, social relations, family relations, transport, work). In these patients, the subjective Qol for social relations is also significantly correlated with their expectations in terms of Qol improvement (work, money, lodging, affective relations, transport). There is no significant correlation between subjective Qol and expectations in patients treated in part-time services. Our results indicate that part time services treat schizophrenic patients with a lower level of global functioning and a higher level of symptom severity compared with ambulatory patients. These results confirm other studies that show no significant difference between these 2 groups in terms of subjective Qol. The subjective Qol in the field of relations (family and social) in ambulatory patients seems particularly sensitive to illness severity, positive symptoms and global functioning level. This has also been reported by other studies. In patients treated in part-time services, the subjective Qol, particularly for living conditions and security, seems sensitive to anxiety and depression. This has also been shown by other studies. Finally, our results underline the importance of patients' expectations in terms of subjective Qol, particularly in the field of relations (family and social) for ambulatory patients.
