They used relatively broad inclusion criteria and imposed no restrictions on language or date of the studies used in the review. Time from service contact to treatment. Proper psychometric studies are however required to standardize DUP definition. The effect-size measure was Hedges’ g.34 This indexed the impact of the specific intervention on the DUP. The only exception was noted in relation to standalone CHR-P services. There were no publication biases and the results were not affected by outliers. Subgroup analyses showed no differences within each subgroup, with the exception of clinical high risk services (Hedges’ g = −0.386, 95% CI = −0.726 to −0.045).

Two influential meta-analyses clearly establish that the duration of untreated psychosis (DUP), the time between the onset of psychosis and initiation of treatment, is correlated with poor outcome. Individual response to treatment can vary in terms of both symptoms and adverse effects…. We extracted meta-analytical DUP data (see “Statistical Analysis” section) and DUP definitions (at onset and endpoint). Importantly, in this study, the average DUP for those who had contacted CHR-P services was 11.2 days compared to 366.5 in FEP services.20 Beyond DUP reduction, the CHR-P services further allow for primary indicated prevention, halving the risk of progression to psychosis.60 This may be particularly important,57 given the lack of robust effects on DUP reduction at the FEP stage.

Across multiple studies, longer DUP is Early intervention programs for schizophrenia and psychosis often combine many elements comprising both pharmaceutical and psychosocial therapies, and may involve enriched therapies that are tailored to an individual’s needs. Collaborative large-scale initiatives adopting well standardized psychometric definitions of DUP and refined study designs are needed to advance knowledge and improve outcomes of FEP. Dominic Oliver is supported by the UK Medical Research Council (MR/N013700/1) and King’s College London member of the MRC Doctoral Training Partnership in Biomedical Sciences. Reduction of duration of untreated psychosis (DUP) is the key strategy of early interventions for improving the outcomes of first-episode psychosis. This model explained over a third of the total between-study variance (R2 = .37; figure 4). While this finding is negative, there is some evidence that initiatives to reduce DUP may be effective in areas where the DUP is particularly long. The period from the onset of frank psychotic symptoms to the start ofadequate treatment, the duration of untreated psychosis (DUP), varies considerablyin patients with first-episode psychosis. Previous research investigating such a relationship was mostly cross-sectional … Negative values indicated reduced DUP in the intervention group and positive values indicated reduced DUP in the control group. Moderate quality evidence finds a large effect of increased risk of homicide, and a small effect of increased risk of deliberate self-harm with longer DUP. Treatments for specific symptoms and populations, Therapies for specific symptoms and populations. We did not restrict inclusion to any specific study design. The second step involved an electronic manual search of references found in the included articles. There was substantial heterogeneity (I2 = 66.4%), most of which was accounted by different definitions of DUP onset (R2 = .88). Details of the protocol for systematic review were registered on PROSPERO (CRD42017057082). Conversely, standalone CHR-P services did significantly reduce DUP (Hedges’ g = −0.386, 95% CI = −0.726 to −0.045). Articles meeting the inclusion criteria for the current systematic review and meta-analysis: (a) were original articles or original data presented as conference abstract, written in English, (b) included patients diagnosed with a psychotic disorder defined according to standard international Diagnostic and Statistical Manual of Mental Disorders (DSM) or International Statistical Classification of Diseases and Related Health Problems (ICD) criteria—any version, (c) were controlled studies with either randomized cluster, cohort, or cohort analytic designs, and (d) reported DUP as a key outcome measure, as defined by each individual article. All the studies had either cohort,17,18,24–27,29,30,45,50 cohort analytic,15,20,28,46 or randomized cluster design.21,51 More information on interventions is detailed in table 1. The research into what has been called “duration of untreated psychosis” (DUP) is extensive. The current meta-analysis has some potential clinical implications. Longer DUP is associated with both poorer response to initial treatment (Kane et al., 2016) and poorer outcomes measured up to 15 years later (Bottlender et al., 2003). Moderate quality evidence also suggests less likelihood of remission with a longer DUP. Multiple meta-analyses clearly establish that the duration of untreated psychosis (DUP)—the time between the onset of psychosis and initiation of treatment to address the psychotic symptoms—is correlated with poor outcomes. The principal finding of this meta-analysis is lack of overall summary evidence for any beneficial impact of controlled interventions for reducing the DUP. Our finding corroborates earlier systematic reviews concluding that the evidence base for effective reductions of DUP was “very limited.”16 Negative findings are always difficult to interpret because “absence of evidence is not equivalent to evidence of absence.”52 However, ours are unlikely to be secondary to low power since the analyses are based on a larger sample compared to previous systematic reviews16 and the overall effect was very small in magnitude. A further 6 studies were multifocus interventions, combining different types of service configuration with community education campaigns and healthcare professional training.15,17,24,25,45,50 It was thus possible to cluster the types of controlled interventions across 5 subgroups: standalone FEP services, standalone CHR-P services, community interventions, healthcare professional training, and multifocus interventions (more detail on the content of each intervention can be seen in supplementary eTable 3). These subgroups were defined by the systematic review that was conducted ahead of the meta-analysis, as indicated below. This meta-analysis has not provided convincing evidence that current approaches to reduce DUP are effective in accomplishing their aim, with the potential exception of CHR-P services. Moreover, when the analyses were stratified within and between the different subgroups the results were overall unchanged. MAIN RESULTS. Introduction. Moher D, Liberati A, Tetzlaff J, Altman DG; PRISMA Group. The search was extended from inception until April 6, 2017. Indeed, we found that the definition of the DUP was unstandardized and associated with significant heterogeneity. Furthermore, the magnitude of the effect size for this study was still small to medium and between-subgroup analysis highlighted no significant effect of subgroup on DUP. OBJECTIVE: Studies of patients experiencing their first episode of psychosis have demonstrated that they typically remain undiagnosed and untreated for 1–2 years. DUP onset was operationalized as patient report of onset of frank psychotic general symptoms in 8 studies,18,24,25,27,29,30,50,51 as patient report of onset of frank psychotic positive symptoms in 4 studies,17,20,26,45 defined psychometrically using PANSS in 2 studies15,28 or unremitting psychotic symptoms for greater than 1 week in 1 study.21 DUP endpoint was operationalized as general commencement of antipsychotic treatment in 12 studies,15,17,18,20,21,24–26,28,30,45,51 30 days’ consistent antipsychotic medication in 2 studies27,50 or first contact with FEP services in 1 study.29 Information on DUP onset and endpoint definition used was missing in one study.46 All but one20 defined the DUP retrospectively.15,17,18,21,24–30,45,46,50,51 Most studies were performed in high-income countries on urban populations,15,17,18,20,21,24–29,45,46,50,51 with the only exception focusing on a rural population in Argentina.30 Three studies18,20,46 focused on service configuration alone as main type of intervention. Forest plot showing results of random effects within-subgroup analysis and overall summary effect. We found that a shorter start DUP (control DUP) leaves less opportunity for reducing DUP, however, this effect was very small and influenced by outliers. We're supporting people to maintain their wellbeing and manage isolation. Duration of untreated psychosis (DUP) is the time period between symptom presentation and treatment, and many define it as the time between the emergence of psychotic symptoms and the first psychiatric hospitalization. Improved patients have a shorter DUP and better premorbid functioning than unimproved patients. Heterogeneity among study point estimates was assessed using Q statistics35 and the proportion of the total variability in the effect size estimates evaluated with the I2 index.35 Given the methodological heterogeneity of the included studies, random effects models36 were employed using the method of DerSimonian and Laird.37, Risk of publication bias was tested by visual inspection of funnel plots in addition to the application of the Egger regression intercept method38 and the Duval and Tweedie “trim and fill” method.39 To further assess the robustness of the results, we performed sensitivity analyses by sequentially removing each study and re-running the analysis.40, To explain any heterogeneity found, meta-regression analyses were conducted when at least 10 studies were available for the specific confounders relating to patients: mean age, gender, ethnicity (% white), marital status (proportion of married subjects), cannabis abuse/dependence (% meeting abuse/dependence criteria), alcohol abuse/dependence (% meeting abuse/dependence criteria), living status (% living independently), migrant status (% non-migrants), psychotic symptom severity at baseline (PANSS), diagnosis (% schizophrenia); relating to the study: length of intervention (months), quality of studies (see below), publication year, continent, healthcare system type (Semashko, Bismarck, market-based), study design (randomized cluster, cohort analytic, cohort), control DUP, definition of DUP onset, definition of DUP endpoint. All studies used similar definitions of FEP, with 12 studies defining it according to DSM-IV,15,20,21,24–29,45,46,50 2 according to DSM-III-R,17,18 1 according to ICD-10,51 and 1 employing both ICD-10 and DSM-IV30. The mean age of the intervention and control groups were 25.5 years (range 21.6–36.6) and 26.4 years (range 22.0–38.0), respectively. PRISMA31 and MOOSE guidelines32 were adhered to throughout to achieve high quality of reporting (supplementary eTables 1 and 2). This suggests the usefulness of psychometric and clinical instruments as a way of reliably defining the onset of DUP. Meta-regression analyses. The database was relatively large with 1964 patients in intervention groups and 1358 in control groups with duration of interventions lasting an average of 31.3 months. The meta-analyses included an overall estimate across all subgroups as well as within-subgroup summary effects and between-subgroups effects. Consequently, the accuracy of DUP definition is the highest in this scenario and was operationalized with standardized psychometric instruments such as the Comprehensive Assessment of At Risk Mental State (CAARMS, version 12/2006), which accurately estimate timing of onset of attenuated and frank psychotic symptoms prospectively.59 Future controlled randomized interventional studies could use similar psychometric instruments to define the DUP. Conclusion: Longer DUP is associated with higher age at presentation, higher negative symptoms, and poor premorbid functioning. What are the treatments for first-episode psychosis? The overall effect for DUP reduction across all the included studies was small (Hedges’ g = −0.12, 95% CI = −0.25 to 0.01) and did not reach significance (P = .077; figure 2).
