Duration of untreated psychosis (DUP) has been associated with poor mental health outcomes. We aimed to meta-analytically estimate the mean and median DUP worldwide, evaluating also the influence of several moderating factors. This PRISMA/MOOSE-compliant meta-analysis searched for non-overlapping individual studies from inception until 9/12/2022, reporting mean ± s.d. or median DUP in patients with first episode psychosis (FEP), without language restrictions. We conducted random-effect meta-analyses, stratified analyses, heterogeneity analyses, meta-regression analyses, and quality assessment (PROSPERO:CRD42020163640). From 12 461 citations, 369 studies were included. The mean DUP was 42.6 weeks (95% confidence interval (CI) 40.6–44.6, k = 283, n = 41 320), varying significantly across continents (p < 0.001). DUP was (in descending order) 70.0 weeks (95% CI 51.6–88.4, k = 11, n = 1508) in Africa; 48.8 weeks (95% CI 43.8–53.9, k = 73, n = 12 223) in Asia; 48.7 weeks (95% CI 43.0–54.4, k = 36, n = 5838) in North America; 38.6 weeks (95% CI 36.0–41.3, k = 145, n = 19 389) in Europe; 34.9 weeks (95% CI 23.0–46.9, k = 11, n = 1159) in South America and 28.0 weeks (95% CI 20.9–35.0, k = 6, n = 1203) in Australasia. There were differences depending on the income of countries: DUP was 48.4 weeks (95% CI 43.0–48.4, k = 58, n = 5635) in middle-low income countries and 41.2 weeks (95% CI 39.0–43.4, k = 222, n = 35 685) in high income countries. Longer DUP was significantly associated with older age (β = 0.836, p < 0.001), older publication year (β = 0.404, p = 0.038) and higher proportion of non-White FEP patients (β = 0.232, p < 0.001). Median DUP was 14 weeks (Interquartile range = 8.8–28.0, k = 206, n = 37 215). In conclusion, DUP is high throughout the world, with marked variation. Efforts to identify and intervene sooner in patients with FEP, and to promote global mental health and access to early intervention services (EIS) are critical, especially in developing countries.

Tobacco smoking is highly prevalent among patients with serious mental illness (SMI), with known deleterious consequences. Smoking cessation is therefore a prioritary public health challenge in SMI. In recent years, several smoking cessation digital interventions have been developed for non-clinical populations. However, their impact in patients with SMI remains uncertain. We conducted a systematic review to describe and evaluate effectiveness, acceptability, adherence, usability and safety of digital interventions for smoking cessation in patients with SMI. PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, PsychINFO and the Cochrane Tobacco Addiction Group Specialized Register were searched. Studies matching inclusion criteria were included and their information systematically extracted by independent investigators. Thirteen articles were included, which reported data on nine different digital interventions. Intervention theoretical approaches ranged from mobile contingency management to mindfulness. Outcome measures varied widely between studies. The highest abstinence rates were found for mSMART MIND (7-day point-prevalent abstinence: 16–40%). Let's Talk About Quitting Smoking reported greater acceptability ratings, although this was not evaluated with standardized measures. Regarding usability, Learn to Quit showed the highest System Usability Scale scores [mean (s.d.) 85.2 (15.5)]. Adverse events were rare and not systematically reported. Overall, the quality of the studies was fair to good. Digitally delivered health interventions for smoking cessation show promise for improving outcomes for patients with SMI, but lack of availability remains a concern. Larger trials with harmonized assessment measures are needed to generate more definitive evidence and specific recommendations.

Functional recovery is a treatment goal that goes beyond symptomatic remission and encompasses multiple aspects of schizophrenia patients’ lives, including quality of life, physical, and mental functioning. There is evidence that long-acting injectable (LAI) treatments promote adherence and reduce rehospitalisation and functional decline, which could facilitate patients’ ability to reach functional recovery. Despite this, LAIs are underused in the first-episode (FEP) and early-phase (EP) patient population, due to physician hesitancy and concerns around stigma. A Delphi panel was held to gain expert consensus on an approach to the domains and assessment of functional recovery elements in FEP and EP schizophrenia patients.
A literature review and input from a steering committee of 5 experts in psychiatry informed statements development for a three-round modified Delphi process. Round one was conducted via one-to-one video conference interviews, and the successive rounds were conducted via electronic surveys, which enabled international collaboration. Statements on the different domains and assessment for functional recovery were presented to 17 psychiatrists, practicing in 7 countries (France, Italy, US, Germany, Spain, Denmark, and UK), experienced in the treatment of schizophrenia with LAIs. Several analysis rules determined whether a statement could progress to the next round and specified the level of agreement required to achieve consensus. Measures of central tendency (mode, mean) and variability (interquartile range) were reported back to help panelists look at their previous responses in the context of the overall group.
A consensus was reached (defined a priori as ≥80% agreement) on all 27 statements covering the dimensions, assessment, and level of achieved functional recovery for FEP and EP patients. The following domains are important to consider when assessing functional recovery: depression, aggressive behaviour, social interaction, family functioning, education/employment, sexual functioning, and leisure activities. Additionally, panellists reached consensus that dimensions should be minimally impairing, if present (excluding sexual functioning) and asked about at every encounter with the patient (excluding sexual functioning and leisure activities). In summary, this Delphi panel yielded agreement that functional recovery is multidimensional and should be assessed regularly as part of usual care on an individual patient level in FEP and EP schizophrenia patients.

Schizophrenia is among the top ten causes of years lost due to disability. Goals of treatment are evolving beyond remission of psychotic symptoms to include physical and mental functioning, quality of life, and long-term functional recovery. Evidence has shown long-acting injectables (LAIs) are beneficial for schizophrenia patients by increasing treatment adherence and decreasing relapse and rehospitalisation. This potentially reduces disease progression and facilitates functional recovery. However, LAIs are underused and often seen as a last resort for first-episode (FEP) and early-phase (EP) patients, due to physicians’ lack of familiarity and stigma.
A three-round modified Delphi panel was held to gain expert consensus on an approach to functional recovery in FEP and EP patients with LAIs. A literature review and input from a steering committee of 5 experts in psychiatry informed the development of statements. Round one was carried out via one-to-one video conference interviews, and the subsequent rounds were conducted via electronic surveys, which enabled international collaboration. Delphi panellists were 17 psychiatrists with schizophrenia treatment experience, practicing in 7 countries (France, Italy, US, Germany, Spain, Denmark, and UK). Several analysis rules determined whether a statement could progress to the next round and specified the level of agreement required to achieve consensus. Measures of central tendencies (mode, mean) and variability (interquartile range) of aggregated responses from the previous round were reported to panelists to understand their response in relation to the group.
There was consensus (defined a priori as ≥80% agreement) on the 8 statements relating to long-term treatment goals and LAI links to functional recovery. LAI treatment in FEP and EP patients increases adherence and reduces treatment burden and functional decline compared to the same and other oral medication. Additionally, there was consensus that LAIs lead to better treatment outcome and functional recovery. Other important factors to achieving functional recovery include patient attitude towards treatment and psychoeducation. Furthermore, consensus was reached that functional recovery and quality of life are linked. In summary, this Delphi panel yielded agreement that functional recovery is a reachable goal for FEP and EP patients and can be enhanced using LAIs.

Background
Psychiatric hospitalization is a major driver of cost in the treatment of schizophrenia. Here, we asked whether a technology-enhanced approach to relapse prevention could reduce days spent in a hospital after discharge.
MethodsThe Improving Care and Reducing Cost (ICRC) study was a quasi-experimental clinical trial in outpatients with schizophrenia conducted between 26 February 2013 and 17 April 2015 at 10 different sites in the USA in an outpatient setting. Patients were between 18 and 60 years old with a diagnosis of schizophrenia, schizoaffective disorder, or psychotic disorder not otherwise specified. Patients received usual care or a technology-enhanced relapse prevention program during a 6-month period after discharge. The health technology program included in-person, individualized relapse prevention planning with treatments delivered via smartphones and computers, as well as a web-based prescriber decision support program. The main outcome measure was days spent in a psychiatric hospital during 6 months after discharge.
ResultsThe study included 462 patients, of which 438 had complete baseline data and were thus used for propensity matching and analysis. Control participants (N = 89; 37 females) were enrolled first and received usual care for relapse prevention followed by 349 participants (128 females) who received technology-enhanced relapse prevention. During 6-month follow-up, 43% of control and 24% of intervention participants were hospitalized (χ2 = 11.76, p<0.001). Days of hospitalization were reduced by 5 days (mean days: b = −4.58, 95% CI −9.03 to −0.13, p = 0.044) in the intervention condition compared to control.
ConclusionsThese results suggest that technology-enhanced relapse prevention is an effective and feasible way to reduce rehospitalization days among patients with schizophrenia.

Background
Antipsychotics are widely used in the treatment of major depressive disorder (MDD), but there has been no comprehensive meta-analytic assessment that examined their use as monotherapy and adjunctive therapy.
MethodsA systematic review and a meta-analysis were conducted on randomized placebo-controlled trials (RCTs) that reported on the efficacy and safety/tolerability of antipsychotics for the treatment of adults with MDD. Data of both monotherapy and adjunctive antipsychotic use were extracted, but analyzed separately using a random-effects model. Co-primary outcomes were study-defined-treatment response and intolerability-related discontinuation. We also illustrated the risk/benefit balance of antipsychotics for MDD, using two-dimensional graphs representing the primary efficacy and safety/tolerability outcome. Secondary outcomes included psychopathology, remission, all-cause-discontinuation, inefficacy-related discontinuation, and adverse events.
ResultsForty-five RCTs with 12 724 patients were included in the analysis. In monotherapy (studies = 13, n = 4375), amisulpride [1.99 (1.55–2.55)], sulpiride [1.50 (1.03–2.17)], and quetiapine [1.48 (1.23–1.78)] were significantly superior to placebo regarding treatment response. However, intolerability-related discontinuations were significantly higher compared to placebo with amisulpride and quetiapine. In adjunctive therapy (studies = 32, n = 8349), ziprasidone [1.80 (1.07–3.04)], risperidone [1.59 (1.19–2.14)], aripiprazole [1.54 (1.35–1.76)], brexpiprazole [1.41 (1.21–1.66)], cariprazine [1.27 (1.07–1.52)], and quetiapine [1.23 (1.08–1.41)] were significantly superior to placebo regarding treatment response. However, of these antipsychotics that were superior to placebo, only risperidone was equivalent to placebo regarding discontinuation due to intolerability, while the other antipsychotics were inferior.
ConclusionResults suggest that there are significant differences regarding the risk/benefit ratio among antipsychotics for MDD, which should inform clinical care.

Background
The COVID-19 pandemic substantially impacted care of patients with schizophrenia treated with long-acting injectable antipsychotics (LAIs). This study examined how clinics adapted operations to maintain a standard of care for these patients after pandemic onset.
MethodsOnline surveys were completed in October-November 2020 by one principal investigator (PI) or PI-appointed designee at 35 clinics participating in OASIS (NCT03919994). Items concerned pandemic impacts on clinic operations, particularly telepsychiatry, and on the care of patients with schizophrenia treated with LAIs.
ResultsAll 35 clinics reported using telepsychiatry; 20 (57%) implemented telepsychiatry after pandemic onset. Telepsychiatry visits increased from 12%-15% to 45%-69% across outpatient visit types after pandemic onset; frequency of no-show and/or canceled telepsychiatry visits decreased by approximately one-third. Nearly half of clinics increased the frequency of telepsychiatry visits for patients with schizophrenia treated with LAIs. Approximately one-third of participants each reported switching patients treated with LAIs to longer injection interval LAIs or to oral antipsychotics. The most common system/clinic- and patient-related barrier for telepsychiatry visits was lower reimbursement rate and access to technology/reliable internet, respectively. Almost all participants (94%) were satisfied with telepsychiatry for maintaining care of patients with schizophrenia treated with LAIs; most predicted a hybrid of telepsychiatry and office visits post-pandemic.
ConclusionsChanges made by clinics after pandemic onset were viewed by almost all participants as satisfactory for maintaining a standard of care for patients with schizophrenia treated with LAIs. Most participants predicted continuing telepsychiatry to support patient care post-pandemic; equitable access to telepsychiatry will be important in this regard.

Study Objectives
Coordinated specialty care (CSC) is widely accepted as an evidence-based treatment for first episode psychosis (FEP). The NAVIGATE intervention from the Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) study is a CSC intervention which offers a suite of evidence-based treatments shown to improve engagement and clinical outcomes, especially in those with shorter duration of untreated psychosis (DUP). Coincident with the publication of this study, legislation was passed by the United States Congress in 2014–15 to fund CSC for FEP via a Substance Abuse and Mental Health Services Administration (SAMHSA) block grant set-aside for each state. In Michigan (MI) the management of this grant was delegated to Network180, the community mental health authority in Kent County, with the goal of making CSC more widely available to the 10 million people in MI. Limited research describes the outcomes of implementation of CSC into community practices with no published accounts evaluating the use of the NAVIGATE intervention in a naturalistic setting. We describe the outcomes of NAVIGATE implementation in the state of MI.
MethodsIn 2014, 3 centers in MI were selected and trained to provide NAVIGATE CSC for FEP. In 2016 a 4th center was added, and 2 existing centers were expanded to provide additional access to NAVIGATE. Inclusion: age 18–31, served in 1 of 4 FEP centers in MI. Data collection began in 2015 for basic demographics, global illness (CGI q3 mo), hospital/ED use and work/school (SURF q3 mo) and was expanded in 2016 to include further demographics, diagnosis, DUP, vital signs; and in 2018 for clinical symptoms with the modified Colorado Symptom Inventory (mCSI q6 mo), reported via an online portal. This analysis used data until 12/31/19. Mixed effects models adjusted by age, sex and race were used to account for correlated data within patients.
ResultsN=283 had useable demographic information and were included in the analysis. Age at enrollment was 21.6 ± 3.0 yrs; 74.2% male; 53.4% Caucasian, 34.6% African American; 12.9 ± 1.7 yrs of education (N=195). 18 mo retention was 67% with no difference by sex or race. CGI scores decreased 20% from baseline (BL) to 18 mo (BL=3.5, N=134; 15–18 mo=2.8, N=60). Service utilization via the SURF was measured at BL (N=172) and 18 mo (N=72): psychiatric hospitalizations occurred in 37% at BL and 6% at 18 mo (p<0.01); ER visits occurred in 40% at BL and 13% at 18 mo (p<0.01). 44% were working or in school at BL and 68% at 18 mo (p<0.01). 21% were on antipsychotics (AP) at BL (N=178) and 85% at 18 mo (N=13) with 8% and 54% on long acting injectable-AP at BL and 18 mo, respectively. Limitations include missing data and lack of a control group.
ConclusionThe implementation of the NAVIGATE CSC program for FEP in MI resulted in meaningful clinical improvement for enrollees. Further support could make this evidence-based intervention available to more people with FEP.

Background
During the COVID-19 pandemic, the use of telemedicine as a way to reduce COVID-19 infections was noted and consequently deregulated. However, the degree of telemedicine regulation varies from country to country, which may alter the widespread use of telemedicine. This study aimed to clarify the telepsychiatry regulations for each collaborating country/region before and during the COVID-19 pandemic.
MethodsWe used snowball sampling within a global network of international telepsychiatry experts. Thirty collaborators from 17 different countries/regions responded to a questionnaire on barriers to the use and implementation of telepsychiatric care, including policy factors such as regulations and reimbursement at the end of 2019 and as of May 2020.
ResultsThirteen of 17 regions reported a relaxation of regulations due to the pandemic; consequently, all regions surveyed stated that telepsychiatry was now possible within their public healthcare systems. In some regions, restrictions on prescription medications allowed via telepsychiatry were eased, but in 11 of the 17 regions, there were still restrictions on prescribing medications via telepsychiatry. Lower insurance reimbursement amounts for telepsychiatry consultations v. in-person consultations were reevaluated in four regions, and consequently, in 15 regions telepsychiatry services were reimbursed at the same rate (or higher) than in-person consultations during the COVID-19 pandemic.
ConclusionsOur results confirm that, due to COVID-19, the majority of countries surveyed are altering telemedicine regulations that had previously restricted the spread of telemedicine. These findings provide information that could guide future policy and regulatory decisions, which facilitate greater scale and spread of telepsychiatry globally.

Background
Lewy body dementia, consisting of both dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), is considerably under-recognised clinically compared with its frequency in autopsy series.
AimsThis study investigated the clinical diagnostic pathways of patients with Lewy body dementia to assess if difficulties in diagnosis may be contributing to these differences.
MethodWe reviewed the medical notes of 74 people with DLB and 72 with non-DLB dementia matched for age, gender and cognitive performance, together with 38 people with PDD and 35 with Parkinson's disease, matched for age and gender, from two geographically distinct UK regions.
ResultsThe cases of individuals with DLB took longer to reach a final diagnosis (1.2 v. 0.6 years, P = 0.017), underwent more scans (1.7 v. 1.2, P = 0.002) and had more alternative prior diagnoses (0.8 v. 0.4, P = 0.002), than the cases of those with non-DLB dementia. Individuals diagnosed in one region of the UK had significantly more core features (2.1 v. 1.5, P = 0.007) than those in the other region, and were less likely to have dopamine transporter imaging (P < 0.001). For patients with PDD, more than 1.4 years prior to receiving a dementia diagnosis: 46% (12 of 26) had documented impaired activities of daily living because of cognitive impairment, 57% (16 of 28) had cognitive impairment in multiple domains, with 38% (6 of 16) having both, and 39% (9 of 23) already receiving anti-dementia drugs.
ConclusionsOur results show the pathway to diagnosis of DLB is longer and more complex than for non-DLB dementia. There were also marked differences between regions in the thresholds clinicians adopt for diagnosing DLB and also in the use of dopamine transporter imaging. For PDD, a diagnosis of dementia was delayed well beyond symptom onset and even treatment.

Introduction:
Lumateperone (ITI-007) is in late-phase clinical development for schizophrenia. Lumateperone has a unique mechanism of action that modulates serotonin, dopamine, and glutamate neurotransmission. This pooled analysis of lumateperone in 3 randomized, double-blind, placebo-controlled studies was conducted to evaluate the safety and tolerability of lumateperone 42mg (ITI-007 60mg).
Methods:Data were pooled from the 3 controlled late-phase studies of lumateperone 42mg in patients with acute exacerbation of schizophrenia. Safety assessments of all patients who received at least one dose of any treatment included treatment-emergent adverse events (TEAEs), changes in laboratory parameters, extrapyramidal symptoms (EPS), and vital signs.
Results:The safety population comprised 1,073 patients (placebo [n=412], lumateperone 42mg [n=406], risperidone [n=255]). TEAEs that occurred in the lumateperone 42mg group at a rate of ≥5% and twice placebo were somnolence/sedation (24.1% vs 10.0%) and dry mouth (5.9% vs 2.2%). Rates of discontinuation due to TEAEs with lumateperone 42mg (0.5%) were similar to placebo (0.5%) and lower than risperidone (4.7%). Mean change in weight and rates of EPS-related TEAEs were less for lumateperone 42mg and placebo patients than risperidone patients. Mean change from baseline in metabolic parameters were similar or smaller for lumateperone 42mg vs placebo. Mean changes were notably higher in risperidone patients vs lumateperone 42mg and placebo for glucose, cholesterol, triglycerides, and prolactin.
Conclusion:In this pooled analysis, lumateperone 42mg showed good tolerability with potential benefits over risperidone for metabolic, prolactin, and EPS risks. The only TEAE that occurred in >10% of lumateperone patients was somnolence/sedation, which was impacted by morning administration; in subsequent studies that administered lumateperone in the evening, somnolence/sedation rates were markedly reduced. These results suggest that lumateperone 42mg may be a promising new treatment for schizophrenia.

Background
There is uncertainty about the incidence of breakthrough psychosis in treatment adherent patients, and the role that factors, such as cumulative antipsychotic exposure, play in this phenomenon.
MethodsIn a nationwide cohort of individuals treated for schizophrenia-spectrum disorders in Finland between 1 January 1996 and 31 December 2015, ‘Breakthrough Psychosis on Antipsychotic Maintenance Medication’ (BAMM) was defined as hospitalization for psychosis despite ongoing continuous treatment with long-acting injectable antipsychotics (LAIs) or oral antipsychotics (OAPs) for ⩾8 weeks. Incidence rates, survival curves, and risk factors were presented.
ResultsIn a cohort of 16 031 continuous LAI treatment episodes with virtually assured adherence [median duration = 441 days, interquartile range (IQR) = 155–1277], BAMM incidence was 31.5%. For 42 867 OAPs treatment episodes (median duration = 483 days, IQR = 167–1491), for whom adherence was modeled by the PRE2DUP method, BAMM incidence was 31.1%. Factors related to illness instability at treatment onset were associated with BAMM, although median time to BAMM was 291 days (IQR = 121–876) for LAIs and 344 days (IQR = 142–989) for OAPs, and 27.4% (N = 1386) of the BAMM events in the LAI, and 32.9% (N = 4378) in the OAP group occurred despite >1 year since last hospitalization at treatment onset. Cumulative antipsychotic exposure was not a consistent risk factor.
ConclusionBAMM was relatively common even when adherence was confirmed with LAIs. Illness instability at treatment onset accounted for most cases, but relapse after years of continuous treatment was still prevalent. There was insufficient evidence to support causality between cumulative antipsychotic exposure and BAMM. Future research needs to address the role of symptom severity and neurobiology in BAMM.

A key consideration in the discussion of maintenance treatment in schizophrenia is how to first help bring patients to the point where acute psychopathology is sufficiently controlled, so that we can focus on consolidating the gains achieved and prevent a recurrence of illness.
The different phases of treatment and response in schizophrenia include the acute phase, wherein we look for response and resolution; remission, where we control symptoms to levels of mild or less and work toward preventing relapse or any exacerbation of psychopathology; and recovery, meaning the ability to function in the community in the workplace, school, family roles, etc.
In preparing patients with schizophrenia for maintenance treatment, clinicians must ensure that they have done everything possible to alleviate the acute signs and symptoms of illness to the extent possible.
There are several questions to consider at this stage: How much improvement is enough? When do we change treatments, and why? What about adverse effects and the locus of care? In the context of this process of deciding how to bring about the best possible treatment response, we must consider that, if a patient is not responding, the diagnosis may need to be reevaluated. Adherence must be assessed and blood levels should be done (if feasible) to ensure that patients have an adequate amount of medication in their system. If blood levels are unavailable and adherence is an issue, the use of long-acting injectable medication should be considered. The clinician might decide to alterthe medication dose—to increase it, or perhaps decrease it if significant side effects are impeding therapeutic response. Adjunct medications or a switching strategy may be employed. Non-pharmacologic therapy, such as cognitive behavioral therapy, which can be effective at reducing symptoms of schizophrenia, should also be considered.

The successful management of schizophrenia is an enormous public health issue. Although antipsychotic medications can be very helpful in reducing rates of relapse and rehospitalization, nonadherence to medication is a frequent cause of exacerbations in psychopathology, psychotic relapse, and rehospitalization. Relapses can have devastating consequences in a variety of clinical and functional domains. Nonadherence can result from a variety of factors that vary from patient to patient and vary over time in individual patients. A number of strategies have been developed to assess and facilitate adherence. The first critical step is clinician awareness of the scope of the problem and consideration of appropriate strategies to address it.

Schizophrenia affects ~1% of the population and is associated with enormous personal suffering, family distress and burden, and tremendous healthcare and societal costs. Although considerable progress has been made in treating this illness enormous challenges remain.
Early detection and treatment are at present a distant goal. There is undue delay between the onset of full-blown psychosis and appropriate diagnosis and treatment. Continuity of care is often spoken about rather than truly implemented. Adverse effects remain a critical challenge, and comorbid medical conditions as well as suicide result in a markedly diminished life expectancy. Substance abuse affects a substantial proportion of patients, creating an impediment to optimum outcome. Nonadherence remains a very common, but inadequately appreciated obstacle to adequate and sustained treatment response and contributes enormously to a high rate of preventable relapse and rehospitalization.
The focus of this CNS Spectrums supplement is to address many of these topics in a clinically relevant manner by reviewing the latest research findings in pharmacologic and behavioral treatments, with an emphasis on evaluating appropriate treatment for each patient while considering the host of issues that should inform our clinical decision-making. Historically, a major focus of treatment has been positive symptom control. Though this is clearly important, negative symptoms, cognitive dysfunction, depression, demoralization, and comorbid substance abuse are also critical targets in enhancing functional outcome. Concepts such as remission and recovery are useful metrics to help establish targets and goals for treatment planning and for creating a framework for assessing outcome.

Schizophrenia is a complex disorder characterized by a broad spectrum of psychopathology. Aggressive efforts to bring the patient into remission should begin immediately after the first episode. Consequences of non-remission include poor prognosis, psychiatric and general medical complications, treatment resistance, and death from medical comorbidities and suicide. Prevention of relapse following remission is critical to the well-being and optimal functioning of patients with schizophrenia.
The key to optimizing patients' outcomes is to ensure a patient's long-term continuation on medication. As treatment discontinuation can greatly impact the progression of the illness and the patient's ultimate outcome, selecting a treatment with maximum treatment effectiveness is optimal. Nonadherence to treatment is extremely prevalent among patients with schizophrenia, due to such factors as impaired cognition, lack of insight, and side effects associated with antipsychotic treatment.
Atypical antipsychotics have shown some advantages over conventional antipsychotics in terms of reducing positive and negative symptoms of schizophrenia, preventing relapse, and incidence of tardive dyskinesia. Injectables and long-acting formulations of antipsychotics offer additional benefits in terms of ensuring treatment adherence.

Background
Long-acting injectable formulations of antipsychotics are treatment alternatives to oral agents.
AimsTo assess the efficacy of aripiprazole once-monthly compared with oral aripiprazole for maintenance treatment of schizophrenia.
MethodA 38-week, double-blind, active-controlled, non-inferiority study; randomisation (2:2:1) to aripiprazole once-monthly 400 mg, oral aripiprazole (10–30 mg/day) or aripiprazole once-monthly 50mg (a dose below the therapeutic threshold for assay sensitivity). (Trial registration: clinicaltrials.gov, NCT00706654.)
ResultsA total of 1118 patients were screened, and 662 responders to oral aripiprazole were randomised. Kaplan–Meier estimated impending relapse rates at week 26 were 7.12% for aripiprazole once-monthly 400mg and 7.76% for oral aripiprazole. This difference (−0.64%, 95% CI −5.26 to 3.99) excluded the predefined non-inferiority margin of 11.5%. Treatments were superior to aripiprazole once-monthly 50mg (21.80%, P⩽0.001).
ConclusionsAripiprazole once-monthly 400mg was non-inferior to oral aripiprazole, and the reduction in Kaplan–Meier estimated impending relapse rate at week 26 was statistically significant v. aripiprazole once-monthly 50 mg.

Background
Long-acting injections (LAIs) of antipsychotic drugs were developed over 40 years ago in an attempt to improve the long-term treatment of schizophrenia.
AimsTo review existing guidelines concerning antipsychotic use generally, and LAIs in particular, and how patients might be identified as potential candidates for LAI treatment.
MethodLiterature review.
ResultsCurrently several first-generation and one second-generation antipsychotic LAIs are available, with others under development. Although the use of LAIs is widespread around the world, patterns of use vary widely. Important considerations regarding the use of LAIs include the indications for long-term pharmacotherapy in schizophrenia in general, the indications for LAIs, the risks associated with LAIs, the need to update guidelines and the issue of cost.
ConclusionsThe use of these injections in first-episode psychosis and treatment-refractory schizophrenia is not currently a focus of recommendations, but should be considered. Long-acting injections remain an underutilised option in many countries despite frequent non-adherence with oral medication and subsequent relapse.
