Psychoeducation Improves Compliance and Outcome in Schizophrenia Without an Increase of Adverse Side Effects: A 7-Year Follow-up of the Munich PIP-Study.

Psychoeducation improves adherence and motivates patients to accept a maintenance therapy as recommended by the guidelines. This would mean a daily consumption of at least 300 chlorpromazine (CPZ) units in the long run and should lead to an increase of the antipsychotic dosage in comparison to patients with treatment as usual (TAU). This raises 2 important questions: whether more side effects are provoked and do the patients have a corresponding benefit with a better outcome. A total of 41 patients with a diagnosis of schizophrenic or schizoaffective disorder were randomized at study entry, either to bifocal psychoeducation (21), or to standard treatment (20). They were compared concerning compliance, type of medication, dosage (CPZ equivalents), motor side effects and number of days in hospital. The average daily antipsychotic medication 2 and 7 years after index discharge was 365 and 354 CPZ-units respectively in the intervention group (IG), but 247 and 279, respectively in the control group (CG). The extent of motor side effects was slightly smaller in the IG, but they showed a small and statistically not significant increase in the rate of tardive dyskinesia (TD) after 7 years. At the 7-year follow-up the patients in the IG had spent 74.7 days in hospital compared to 243.4 days for the patients in the CG (P < .05). The course of illness was significantly better in the IG without increasing motor side-effects. Therefore, psychoeducation should be integrated more systematically into the routine treatment. These data are part of a previous study, published 2007, with a sample size of 48 patients. Seven patients-3 of the IG and 4 of the CG-could not be included, because they were not able to complete the very complex "Computer-based kinematic analysis of motor performance." In this article all conclusions are referred to the new sample size, therefore some results are slightly different in comparison to the previous data.

Valproate for schizophrenia.

BACKGROUND: Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment. In these cases, various add-on medications are used; valproate is one of these. OBJECTIVES: To review the effects of valproate for the treatment of schizophrenia and schizophrenia-like psychoses. SEARCH STRATEGY: We searched the Cochrane Schizophrenia Group's register (last update February 2007). This register is compiled by methodical searches of BIOSIS, CINAHL, Dissertation abstracts, EMBASE, LILACS, MEDLINE, PSYNDEX, PsycINFO, RUSSMED, Sociofile, supplemented with hand searching of relevant journals and numerous conference proceedings. We also contacted a pharmaceutical company and authors of relevant studies in order to identify further trials. SELECTION CRITERIA: We included all randomised controlled trials comparing valproate to antipsychotics or to placebo (or no intervention), whether as the sole agent or as an adjunct to antipsychotic medication for the treatment of schizophrenia and/or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS: We independently inspected citations and, where possible, abstracts, ordered papers and re-inspected and quality assessed these. Data were extracted independently by at least two reviewers. We analysed dichotomous data using relative risks (RR) and the 95% confidence intervals (CI). We analysed continuous data using weighted mean differences. Where possible we calculated the number needed to treat (NNT) or number needed to harm statistics. MAIN RESULTS: The update search identified two further relevant studies, thus the review currently includes seven studies with a total of 519 participants. All trials examined the effectiveness of valproate as an adjunct to antipsychotics. With one exception the studies were small, short-term and incompletely reported. Adding valproate was as acceptable as adding placebo to antipsychotic drugs (6 RCT, n=270, RR leaving the study early 1.7 CI 0.9 to 3.2). No significant effect of valproate as an adjunct to antipsychotic medication on the participants' global state or the general mental state at the endpoint was evident. However, one study showed a quicker onset of action in the combination group (Casey 2003). A single small study found the participants in the valproate group to be less aggressive than the control group (n=30, WMD -3.8, CI -5.1 to -2.5). Participants receiving valproate more frequently experienced sedation than those in the placebo group. In a single small study valproate significantly reduced tardive dyskinesia (n=30, WMD -3.3, CI -4.9 to -1.7). The effects of valproate on important subgroups such as those with schizophrenia and aggressive behaviour or those with schizoaffective disorder are unknown. AUTHORS' CONCLUSIONS: Based on currently available randomised trial-derived evidence, there are no data to support or to refute valproate as a sole agent for schizophrenia. There is some evidence for positive effects on aggression and tardive dyskinesia, but given that these results were based on only a single small study they cannot be considered robust. Given the paucity of the available database further large, simple well-designed and reported trials are necessary. Ideally these would focus on people with schizophrenia and aggression, on those with treatment resistant forms of the disorder and on those with schizoaffective disorders.

Psychoeducation in schizophrenia: 7-year follow-up concerning rehospitalization and days in hospital in the Munich Psychosis Information Project Study.

OBJECTIVE: According to most of the relevant guidelines, psychoeducation is considered a basic part of routine therapy for patients with schizophrenia; scientific proofs of its efficacy are based mainly on the results of 1- and 2-year follow-ups. Therefore, the long-term effects of psychoeducation over a period of 7 years were investigated in regard to rehospitalization rates and hospital days. METHOD: Of 101 patients with DSM-III-R or ICD-9 schizophrenia randomly allocated to either an intervention group or a control group between 1990 and 1994, 48 patients were available for follow-up after 7 years. During their index stay, the 24 patients of the intervention group and their key relatives each received a separate psychoeducational group therapy. The 24 patients of the control group received the usual treatment. After index discharge, all 48 patients received a comparable outpatient treatment. Main outcome measures were rehospitalization rate, number of intervening hospital days, compliance, and mean number of consumed chlorpromazine (CPZ) units. RESULTS: Seven years after index discharge, the rate of rehospitalization was 54% in the intervention group and 88% in the control group. The rate of rehospitalization per patient was 1.5 in the intervention group and 2.9 in the control group (p < .05). In the intervening period, the mean number of hospital days spent in a psychiatric hospital was 75 in the intervention group and 225 days in the control group. (p < .05). The mean number of consumed CPZ units after 7 years was 354 in the intervention and 267 in the control group. CONCLUSIONS: Seven years after psychoeducational group therapy, significant effects on the long-term course of the illness can be found. Therefore, the integration of psychoeducation into standard therapy for schizophrenia should become obligatory.
