Effectiveness of Family Intervention for Preventing Relapse in First-Episode Psychosis Until 24 Months of Follow-up: A Systematic Review With Meta-analysis of Randomized Controlled Trials.

ABSTRACT:

Background

Relapse risk during the early years of first-episode psychosis (FEP) considerably increases the risk of chronicity. The effectiveness of family intervention for psychosis (FIp) for preventing relapse after FEP remains unknown. We assessed the effectiveness of FIp until 24 months of follow-up for preventing relapse and other relapse-related outcomes in patients following FEP.

Methods

We searched the Cochrane, PubMed, PsycINFO, and ProQuest databases in June 2018. A systematic review with meta-analysis of randomized controlled trials (RCTs), sensitivity analyses, and publication bias were performed, comparing to treatment as usual (TAU) or TAU plus other psychosocial interventions. Outcomes assessed were relapse rates, duration of hospitalization, psychotic symptoms, and functionality. Risk ratios (RRs) and (standardized) mean differences (SMD; MD) were calculated.

Results

Of the 2109 records retrieved, 14 (11 RCTs) were included. Pooled results showed that FIp was effective for preventing relapse (RR = 0.42; 95% CI = 0.29 to 0.61) compared to TAU and/or other psychosocial interventions. It also proved effective when compared to TAU alone (RR = 0.36) and TAU plus other psychosocial interventions (RR = 0.48). FIp showed benefits in reducing duration of hospitalization (TAU, MD = -3.31; other interventions, MD = -4.57) and psychotic symptoms (TAU, SMD = -0.68), and increased functionality (TAU, SMD = 1.36; other interventions, SMD = 1.41).

Conclusions

These findings suggest that FIp is effective for reducing relapse rates, duration of hospitalization, and psychotic symptoms, and for increasing functionality in FEP patients up to 24 months. The study's main limitations were the inclusion of published research only; authors were not contacted for missing/additional data; and high heterogeneity regarding relapse definition was observed.

Project description:ObjectiveThe majority of first-episode psychosis (FEP) patients reach clinical remission; however, rates of relapse are high. This study sought to undertake a systematic review and meta-analysis of randomized controlled trials (RCTs) to determine the effectiveness of pharmacological and non-pharmacological interventions to prevent relapse in FEP patients.MethodsSystematic review and meta-analysis of RCTs.ResultsOf 66 studies retrieved, 18 were eligible for inclusion. Nine studies investigated psychosocial interventions and 9 pharmacological treatments. The analysis of 3 RCTs of psychosocial interventions comparing specialist FEP programs vs treatment as usual involving 679 patients demonstrated the former to be more effective in preventing relapse (odds ratio [OR]=1.80, 95% confidence interval [CI]=1.31-2.48; P<.001; number needed to treat [NNT]=10). While the analysis of 3 different cognitive-behavioral studies not specifically intended at preventing relapse showed no further benefits compared with specialist FEP programs (OR=1.95, 95% CI=0.76-5.00; P=.17), the combination of specific individual and family intervention targeted at relapse prevention may further improve upon these outcomes (OR=4.88, 95% CI=0.97-24.60; P=.06). Only 3 small studies compared first-generation antipsychotics (FGAs) with placebo with no significant differences regarding relapse prevention although all individual estimates favored FGAs (OR=2.82, 95% CI=0.54-14.75; P=.22). Exploratory analysis involving 1055 FEP patients revealed that relapse rates were significantly lower with second-generation antipsychotics (SGAs) compared with FGAs (OR=1.47, 95% CI=1.07-2.01; P<.02; NNT=10).ConclusionsSpecialist FEP programs are effective in preventing relapse. Cognitive-based individual and family interventions may need to specifically target relapse to obtain relapse prevention benefits that extend beyond those provided by specialist FEP programs. Overall, the available data suggest that FGAs and SGAs have the potential to reduce relapse rates. Future trials should examine the effectiveness of placebo vs antipsychotics in combination with intensive psychosocial interventions in preventing relapse in the early course of psychosis. Further studies should identify those patients who may not need antipsychotic medication to be able to recover from psychosis.

Project description:BACKGROUND:Different effectiveness profiles among antipsychotics may be a key point to optimize treatment in patients suffering a first episode of psychosis to impact on long-term outcome. The aim of this study is to compare the clinical effectiveness of olanzapine, risperidone, haloperidol, aripiprazole, ziprasidone, and quetiapine in the treatment of first episode of psychosis at 3-year follow-up. METHOD:From February 2001 to January 2011, 2 phases of a prospective, randomized, open-label study were undertaken. A total of 376 first-episode drug-naïve patients were randomly assigned to olanzapine (n?=?55), risperidone (n?=?63), haloperidol (n?=?56), aripiprazole (n?=?78), ziprasidone (n?=?62), or quetiapine (n?=?62) and followed up for 3 years. The primary effectiveness measure was all cause of treatment discontinuation. In addition, an analysis based on intention-to-treat principle was conducted in the analysis for clinical efficacy. RESULTS:The overall dropout rate at 3 years reached 20.75%. Treatment discontinuation rates were significantly different among treatment groups (olanzapine?=?69.09, risperidone?=?71.43, aripiprazole?=?73.08%, ziprasidone?=?79.03%, haloperidol?=?89.28%, and quetiapine?=?95.53%) (?2?=?79.86; P?=?.000). Statistically significant differences in terms of lack of efficacy, adherence, and tolerability were observed among treatment groups along the 3-year follow-up, determining significant differences in time to all-cause discontinuation (log-rank?=?92.240; P?=?.000). Significant differences between treatments were found in the categories of sleepiness/sedation, increased sleep duration, akinesia, weight gain, ejaculatory dysfunction, extrapyramidal-symptoms, and amenorrhea. CONCLUSIONS:Olanzapine, risperidone, and aripiprazole presented advantages for the first-line treatment of first episode of psychosis in terms of effectiveness. Identifying different discontinuation patterns may contribute to optimize treatment selection after first episode of psychosis.ClinicalTrials.gov Identifier: NCT02526030 https://clinicaltrials.gov/show/NCT02526030.
