BACKGROUND: Anti-psychotic drugs are the mainstay treatment for schizophrenia and similar psychotic disorders. Long-acting depot injections of drugs such as fluspirilene are extensively used as a means of long-term maintenance treatment. OBJECTIVES: To assess the effects of depot fluspirilene versus placebo, oral anti-psychotics and other depot antipsychotic preparations for people with schizophrenia in terms of clinical, social and economic outcomes. SEARCH STRATEGY: Relevant trials were identified by searching Biological Abstracts (1982-1998), Cochrane Library (Issue 2, 1998), Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1980-1998), MEDLINE (1966-1998) and PsycLIT (1974-1998). References of all identified trials were also inspected for more studies. SELECTION CRITERIA: All relevant randomised trials focusing on people with schizophrenia where depot fluspirilene, oral anti-psychotics or other depot preparations were compared. Outcomes such as death, clinically significant change in global function, mental state, relapse, hospital admission, adverse effects and acceptability of treatment were sought. DATA COLLECTION AND ANALYSIS: Studies were reliably selected, quality rated and data extracted. For dichotomous data, Peto odds ratios (OR) with the 95% confidence intervals (CI) were estimated. Where possible, the number needed to treat statistic (NNT) was calculated. Analysis was by intention-to-treat. Normal continuous data were summated using the weighted mean difference (WMD). Scale data were presented only for those tools that had attained pre-specified levels of quality. MAIN RESULTS: Seven studies were included. Most comparisons included very few participants. There are no convincing data showing fluspirilene decanoate's advantage over oral chlorpromazine or other depot antipsychotics. No study reported on hospital and service outcomes or commented on participants' overall satisfaction with care. Economic outcomes were not recorded by any of the included studies. REVIEWER'S CONCLUSIONS: The total numbers in each comparison were small and there were no clear differences demonstrated between fluspirilene and oral medication or other depots. The choice of whether to use fluspirilene as a depot medication and whether it has advantages over other depots, cannot, at present, be informed by trial-derived data. Well-conducted and reported randomised trials are still needed to inform practice.
