Abstract
BACKGROUND Schizophrenia and schizoaffective disorder require long-term antipsychotic treatment with antipsychotic medications, but poor medication adherence can lead to increased health care utilization and costs. Long-acting injectable antipsychotics (LAIs) offer potential therapeutic advantages in that they require less frequent dosing and improved medication adherence. South Carolina has the highest adoption of LAIs among US states, making it an ideal population for comparing the effectiveness of LAIs vs oral antipsychotics (OAPs) in treating schizophrenia or schizoaffective disorder. OBJECTIVE To evaluate the effect of LAIs compared with OAPs on medication adherence, health care resource utilization, and costs among South Carolina Medicaid beneficiaries with schizophrenia or schizoaffective disorder. METHODS South Carolina Medicaid beneficiaries with at least 1 claim for an LAI or OAP between January 1, 2015, and December 31, 2018, aged 18 to 65, with at least 2 claims with diagnoses of schizophrenia or schizoaffective disorder were included. Propensity scores (PSs) were calculated using logistic regression adjusting for confounders and predictors of the outcome. We estimated the "average treatment effect on the treated" by employing PS-weighted t-tests and chi-square tests. RESULTS A total of 3,531 patients met the inclusion criteria, with 1,537 (44.5%) treated with LAIs and 1,994 (56.5%) treated with OAPs. In PS-weighted analyses, the LAI cohort had a greater proportion of days covered than the OAP cohort with a 365-day fixed denominator (69% vs 64%; P < 0.0001), higher medication possession ratio with a variable denominator while on therapy (85% vs 80%; P < 0.0001), and higher persistence (82% vs 64%; P < 0.0001). The average number of inpatient visits and emergency department visits did not significantly differ between cohorts (0.28 hospitalizations, P = 0.90; 3.68 vs 2.96 emergency department visits, P = 0.19). The number of outpatient visits, including visits for medication administration, were greater in the LAI cohort (23.1 [SD 24.2]) vs OAP (16.9 [SD 21.2]; P < 0.0001); however, including the costs for medication administration visits, outpatient costs (per member) were approximately $2,500 lower in the LAI cohort (P < 0.0001). The number of pharmacy visits was greater in the OAP cohort (LAI 21.0 [SD 17.0] vs OAP 23.0 [SD 15.0]; P = 0.006). All-cause total costs were greater in the LAI cohort ($26,025 [SD $29,909]) vs the OAP cohort ($17,291 [SD $25,261]; P < 0.0001) and were driven by the difference in pharmaceutical costs (LAI $15,273 [SD $16,183] vs OAP $4,696 [SD $10,371]; P < 0.0001). CONCLUSIONS Among South Carolina Medicaid beneficiaries, treatment with LAIs for schizophrenia or schizoaffective disorder was associated with greater medication adherence rates. Patients using LAIs had higher drug costs and total costs, but lower outpatient and total nondrug costs compared with those using OAPs.

Abstract
AIM To evaluate the impact of timing of aripiprazole once-monthly (AOM) initiation on healthcare resource utilization (HCRU), risk of hospitalization, and healthcare costs in patients with schizophrenia. METHODS A retrospective cohort study was conducted using data from the Merative MarketScan database (01/01/2013-12/31/2019). Adults aged ≥18 years with a new episode of care for schizophrenia and an AOM claim were included. Patients were classified into two cohorts based on the time between the first schizophrenia diagnosis and the first AOM claim (early cohort: ≤1 year; late cohort: >1 year). All-cause and psychiatric-specific HCRU, risk of hospitalization, and healthcare costs were evaluated over 1-year post-AOM initiation. The relationship between the timing of AOM initiation and HCRU was evaluated using negative binomial regression, and healthcare costs using generalized linear models (log-link with gamma distribution). Logistic regression was used to estimate the likelihood of hospitalization during the follow up period for both all-cause and psychiatric-specific hospitalization. RESULTS A total of 945 patients were included (early cohort: n = 525; late cohort: n = 420). At baseline, the early cohort had lower mean age, a greater proportion of males, and a lower mean Charlson Comorbidity Index score than the late cohort (all p < .05). After adjusting for baseline demographic and clinical characteristics, all-cause and psychiatric-specific hospitalization during the 1-year follow-up period were statistically significantly higher for the late cohort versus the early cohort (all-cause: incident rate ratio [IRR] = 1.63, 95% confidence interval [CI]: 1.28-2.07, p < .01; psychiatric-specific: IRR = 1.93, 95% CI: 1.46-2.55, p < .01). The early cohort had statistically significantly lower adjusted all-cause ($21,686 versus $29,033; p = .0002) and psychiatric-specific ($24,414 versus $32,461; p = .0002) healthcare costs versus the late cohort. LIMITATIONS This study utilized claims data, which are intended for administrative purposes rather than for research. CONCLUSIONS This analysis extends previous evidence for the benefits of AOM in patients with new episodes of schizophrenia, by demonstrating lower HCRU, risk of hospitalization, and healthcare costs with early AOM initiation compared with later initiation.

Abstract
OBJECTIVE A post hoc analysis of the Disease Recovery Evaluation and Modification (DREaM) study was conducted to evaluate time to first major treatment failure (ie, arrest/incarceration or psychiatric hospitalization) in participants with recent-onset schizophrenia or schizophreniform disorder treated with paliperidone palmitate (PP) versus oral antipsychotics (OAPs). METHODS DREaM was an open-label, delayed-start, randomized, multipart trial consisting of: Part I, 2-month oral run-in; Part II, 9-month disease progression phase (PP or OAP); and Part III, 9 months of additional treatment (PP/PP; OAP re-randomized: OAP/OAP or OAP/PP). PP/PP and OAP/OAP comprised the 18-month extended disease progression (EDP) analysis. RESULTS In Part II (PP, n = 78; OAP, n = 157), similar proportions of participants experienced a major treatment failure across groups (PP: 12.8 %; OAP: 13.4 %); no difference in time to first major treatment failure was identified (P = 0.918). Significant differences favoring PP emerged after 9 months; in Part III, no participants in the PP/PP group, 3.5 % of participants in the OAP/PP group, and 15.9 % in the OAP/OAP group experienced a major treatment failure (P = 0.002). In the EDP analysis, 10.2 % (PP/PP) and 25.4 % (OAP/OAP) of participants experienced a major treatment failure (P = 0.045; number needed to treat = 6). Safety results were similar between groups and consistent with the known safety profile of PP in adults with schizophrenia. CONCLUSIONS Initiation of PP during the early stages of schizophrenia spectrum disorders significantly delayed time to hospitalization and arrest/incarceration, outcomes with important personal and economic consequences, compared with OAP during this 18-month study.

Abstract
OBJECTIVES To evaluate the utilisation and persistence of antipsychotics for the treatment of schizophrenia in Australia. METHODS A retrospective study using the Australian Pharmaceutical Benefits Scheme database of a representative 10% sample. All adults with schizophrenia who were dispensed three or more supplies of oral (including clozapine) or long-acting injectable antipsychotics between 1 June 2015 and 31 May 2020 were included. Persistence time in treatment was evaluated using survival analysis and Cox hazard ratios. RESULTS In all, 26,847 adults with schizophrenia were studied. Oral second-generation antipsychotics were more frequently dispensed than the other antipsychotic groups studied. Median treatment persistence times were 18.3 months for second-generation antipsychotic long-acting injectables, 10.7 months for oral second-generation antipsychotics and were significantly lower for both formulations of first-generation antipsychotics at 5.2 months (long-acting injectables) and 3.7 months (oral). The median persistence time for clozapine was significantly longer than all other antipsychotics groups. CONCLUSIONS Oral second-generation antipsychotics and second-generation antipsychotic long-acting injectables accounted for over 75% and 13% of all antipsychotics in Australia, respectively. Concerns over medication adherence and subsequent relapse have not translated into increased long-acting injectable usage despite their significantly longer persistence. Clozapine, the single most 'persistent' antipsychotic, was only used in 9% of people, although up to a third of all cases are likely to be treatment-resistant. Our data suggest clinicians should give consideration to the earlier use of second-generation antipsychotic long-acting injectables and clozapine, to ameliorate prognosis in schizophrenia.

Abstract
AIM Long acting injectable (LAI) antipsychotics are an alternative to oral antipsychotic (OAP) treatment and may be beneficial for patients in the early stages of schizophrenia. This study aims to provide a comprehensive review on the efficacy of first-generation and second-generation LAI antipsychotics in recent-onset, first-episode, and early psychosis patients. METHODS MEDLINE, EMBASE, PsycINFO, and Web of Science Core databases were used to search for studies that used LAIs in early psychosis patients. Studies published up to 06 Jun 2019 were included with no language restrictions applied. Inclusion criteria were a diagnosis of schizophrenia or related disorder, where patients were in their first episode or had a duration of illness ≤5 years. RESULTS 33 studies were included: 8 RCTs, 4 post-hoc analyses, 2 case reports, and 19 naturalistic studies. The majority of studies evaluated risperidone LAIs (N = 14) and paliperidone palmitate (N = 10), while the remainder investigated fluphenazine decanoate (N = 3), flupentixol decanoate (N = 2), and aripiprazole (N = 1). Two studies did not specify the LAI formulation used, and one cohort study compared the efficacy of multiple different LAI formulations. CONCLUSIONS While the majority of data is based on naturalistic studies investigating risperidone LAIs or paliperidone palmitate, LAIs may be an effective treatment for early psychosis patients in terms of adherence, relapse reduction, and symptom improvements. There is still a need to conduct more high quality RCTs that investigate the efficacy of different LAI formulations in early psychosis patients.

Abstract
PURPOSE/BACKGROUND Currently the longest-acting antipsychotic formulation widespread clinical use is paliperidone 3-monthly injection (PP3M). While its efficacy has been shown in rigorous trials, there are few data relating to its effect on hospitalisation in normal clinical practice. METHODS/PROCEDURES This was a mirror-image study (3 years before; 2 years after) of hospitalisations before and after beginning paliperidone 1-monthly (PP1M) and switching to 3-monthly within 18 months. All consecutive patients prescribed paliperidone long-acting injections with its licence (F20 schizophrenia diagnosis; 18-65 years) were included. The setting was an urban, specialist mental health organisation In London, UK. FINDINGS/RESULTS In total 378 patients were initiated on PP3M during the study period. After applying inclusion criteria, 76 patients were retained and followed-up for 2 years. Mean duration of PP1M use before starting 3-monthly injections was 6 months (range 3-18 months). Of the 76 patients initiated, 13 patients discontinued PP3M within 2 years of starting PP1M or were lost to follow-up. Mean hospitalisations per patient per year fell from 0.55 (SD 0.46) before paliperidone to 0.05 (SD 0.19) after initiation (p < 0.001). Only 5 of 76 PP1M/PP3M participants were hospitalised during the 2-year follow up. The mean number of bed days per year before paliperidone initiation was 32.2 (SD 44.3) and after paliperidone initiation it was 23.0 (SD 53.2) (p = 0.004). Almost all of the bed days after initiation were associated with the index admission during which PP1M was started. IMPLICATIONS/CONCLUSIONS In patients stabilised on PP1M and switched to PP3M in normal clinical practice, rehospitalisation is very uncommon and much reduced compared with previous treatments.

Abstract
OBJECTIVE This study aimed to determine the hospitalization rates, length of stay, age at the time of admission, and sex distribution for major psychiatric disorders in children and adolescents and provide a reference for early intervention for these diseases and distribution of medical resources in hospitals. METHODS We screened 4,423 patients in the child and adolescent wards of the Anhui Provincial Mental Health Center from 2001 to 2020, and examined the top four (81.1%) mental health disorders that accounted for the overall proportion of patients admitted, namely schizophrenia (SCZ) (45.7%), depressive disorder (DD) (14.5%), bipolar disorder (BD) (9.3%), and childhood emotional disorder (CED) (11.6%), and for each disorder, the percentage of hospitalization, length of stay, age at admission, and sex distribution were analyzed. RESULTS From 2001 to 2020, there was a significantly decreasing trend in the proportion of hospitalizations for SCZ (p < 0.001) and an increasing trend for depression and CED (p < 0.001). In terms of length of stay, SCZ was significantly longer than the other three disorders (p < 0.001), whereas there was no significant difference between DD, BD, and CED, and there was no significant trend in length of stay for any of the four disorders. The age at admission for CED was significantly lower than that for the other three disorders (p < 0.001). There was a decreasing trend in the age at admission for DD (p = 0.011) and an increasing trend for BD (p = 0.001). A significant increase in the number of female patients admitted for SCZ, DD, and CED was observed, while there was no significant change in the sex ratio for BD. CONCLUSION Although there is a significant downward trend in the percentage of hospitalizations for SCZ, it is still the most common psychiatric disorder in children and adolescents. We observed a significant increase in the percentage of hospitalizations for DD and CED. In addition, the proportion of female patients being hospitalized is on the rise, and this aspect requires continuous attention.

Abstract
BACKGROUND This double-blind (DB), randomized, parallel-group study was designed to evaluate efficacy and safety of paliperidone palmitate 6-month (PP6M) formulation relative to paliperidone palmitate 3-month (PP3M) formulation in patients with schizophrenia. METHODS Following screening, patients entered an open-label (OL) maintenance phase and received 1 injection cycle of paliperidone palmitate 1-month (PP1M; 100 or 150 mg eq.) or PP3M (350 or 525 mg eq.). Clinically stable patients were randomized (2:1) to receive PP6M (700 or 1000 mg eq., gluteal injections) or PP3M (350 or 525 mg eq.) in a 12-month DB phase; 2 doses of PP6M (corresponding to doses of PP1M and PP3M) were chosen. RESULTS Overall, 1036 patients were screened, 838 entered the OL phase, and 702 (mean age: 40.8 years) were randomized (PP6M: 478; PP3M: 224); 618 (88.0%) patients completed the DB phase (PP6M: 416 [87.0%]; PP3M: 202 [90.2%]). Relapse rates were PP6M, 7.5% (n = 36) and PP3M, 4.9% (n = 11). The Kaplan-Meier estimate of the difference (95% CI) between treatment groups (PP6M - PP3M) in the percentages of patients who remained relapse free was -2.9% (-6.8%, 1.1%), thus meeting noninferiority criteria (95% CI lower bound is larger than the pre-specified noninferiority margin of -10%). Secondary efficacy endpoints corroborated the primary analysis. Incidences of treatment-emergent adverse events were similar between PP6M (62.1%) and PP3M (58.5%). No new safety concerns emerged. CONCLUSIONS The efficacy of a twice-yearly dosing regimen of PP6M was noninferior to that of PP3M in preventing relapse in patients with schizophrenia adequately treated with PP1M or PP3M.

Abstract
OBJECTIVE Schizophrenia is a chronic, debilitating psychiatric disorder with a high risk of relapse. Nonadherence to medication is a significant contributor to poor outcomes. Although long-acting injectable (LAI) antipsychotics prevent the relapse of schizophrenia, several factors present obstacles to the use of LAI antipsychotics, and clinical guidelines for LAI antipsychotics remain limited. To provide clinical recommendations, the Taiwanese Society of Biological Psychiatry and Neuropsychopharmacology (TSBPN) developed consensus statements for the effectiveness, target populations, initiation timing, and particular clinical situations for the use of LAI antipsychotics in patients with schizophrenia. METHODS After a systematic literature review, a working group drafted consensus statements for the selected clinical topics and determined the levels of evidence-based recommendation based on the latest World Federation of Societies of Biological Psychiatry grading system. A scientific committee evaluated the draft statements and decided the final recommendations regarding the grades by anonymous voting after incorporating clinical experience and practice into the evidence from research. RESULTS The TSBPN proposed ten consensus statements for the application of LAI antipsychotics. The current evidence supported that LAI antipsychotics could be a treatment option for all schizophrenia patients, including first-episode patients. LAI antipsychotics could be initiated both during an acute psychotic episode and when patients are stable. The consensus also gave recommendations for particular clinical situations with insufficient scientific data, such as for use in elderly or adolescent patients, patients with treatment-resistant schizophrenia, and breakthrough psychosis, and strategies to assist patients/caregivers with decision making. CONCLUSIONS The consensus statements developed by the TSBPN provide evidence-based clinical recommendations and could give clinicians more confidence when prescribing LAI antipsychotics to treat schizophrenia, thereby improving treatment outcomes.

Abstract
AIMS There is increasing evidence showing the importance of long-acting injectable antipsychotics in the management of schizophrenia, especially in terms of improving patient medication compliance. A panel of experienced clinicians in Hong Kong mapped out a set of consensus statements with an aim to facilitate the understanding and use of long-acting injectable antipsychotics among local physicians. METHODS Eight discussion areas regarding long-acting injectable antipsychotics were selected by the chairman of the consensus group. A series of meetings were held for the panelists to discuss the published literature and their clinical experience, followed by the drafting of consensus statements. At the final meeting, each consensus statement was voted on anonymously by all members based on its practicability of recommendation in Hong Kong. RESULTS A total of 12 consensus statements on the rational use of long-acting injectable antipsychotics were established and accepted by the consensus group. CONCLUSION The consensus statements aim to provide practical guidance for Hong Kong physicians on the use of long-acting injectable antipsychotics in schizophrenia patients. These statements may also serve as a reference for doctors in other parts of the Asia-Pacific region.

Abstract
AIM We aimed to characterize youth hospitalization trends in a psychiatric inpatient unit from a large, public university hospital with a broad catchment area in Milan, Italy. METHODS Hospitalization data of patients with an age at admission ≤ 35 were retrospectively retrieved over a time span of 15 years. The sample was comprised of 1982 admissions to a psychiatric ward, aggregated into ICD-10 diagnostic clusters and then analysed. We investigated the epidemiological trends with a focus on age at admission, gender, nationality and hospitalization rates, length of stay and "revolving door" readmissions within a year. RESULTS Hospitalization rates increased for eating Disorders and decreased for non-affective psychotic disorders; median length of stay generally decreased; hospitalization rates for foreign youth increased, in particular for those diagnosed with non-affective psychotic disorders, personality disorders, and substance-related and addictive disorders. The revolving door phenomenon was also associated with non-affective psychoses and neurodevelopmental disorders, while found to increase for eating disorders. CONCLUSIONS Hospitalization patterns reflect the general increase of foreign youth in the suburban tissue of a large metropolitan area like Milan. However, our data might underestimate the constant growth of mental health problems in foreign youth due to a generally lower access to services. Novel pharmacological treatments and early intervention programs might explain the decrease of hospitalization duration and hospitalization rate for youth with non-affective psychoses. The observed increase in hospitalization for young patients with eating disorders sustains the development of adequate policies tailored towards specialty wards.

Abstract
These updated guidelines from the British Association for Psychopharmacology replace the original version published in 2011. They address the scope and targets of pharmacological treatment for schizophrenia. A consensus meeting was held in 2017, involving experts in schizophrenia and its treatment. They were asked to review key areas and consider the strength of the evidence on the risk-benefit balance of pharmacological interventions and the clinical implications, with an emphasis on meta-analyses, systematic reviews and randomised controlled trials where available, plus updates on current clinical practice. The guidelines cover the pharmacological management and treatment of schizophrenia across the various stages of the illness, including first-episode, relapse prevention, and illness that has proved refractory to standard treatment. It is hoped that the practice recommendations presented will support clinical decision making for practitioners, serve as a source of information for patients and carers, and inform quality improvement.

Early Interv Psychiatry 2019; 13:1357-1365. [PMID: 30548103 DOI: 10.1111/eip.12770] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 10/03/2018] [Accepted: 11/04/2018] [Indexed: 12/31/2022]
Abstract
AIM Duration of untreated psychosis in early schizophrenia impacts long-term outcomes. Because long-acting injectable (LAI) antipsychotic drugs improve adherence in early-stage patients, they could reduce additional time in uncontrolled psychosis (TUP) during the critical period of the illness. However, the long-term benefit of early LAI use over oral formulations has not been quantified. This study explores the potential magnitude of the benefit with a simulation approach. METHODS A microsimulation models the effects of 11 treatment pathways reflecting alternative decisions on whether and when LAI agents are used during a "calibration phase" that starts at treatment entry and lasts until the end of the 3-year critical period. Treatment failure prolongs time in psychosis. Long-term outcomes are predicted over the ensuing 7-year period as a function of TUP. RESULTS An "early LAI" pathway where LAI treatment follows the second oral treatment failure is compared to an oral-only pathway. Under these pathways, 69% and 46% of patients, respectively, are estimated to exit the calibration phase with adequate symptom control (total positive and negative syndrome scale score below 68). Relative to the oral-only pathway, the early LAI pathway is predicted to increase competitive employment by 39% (25% vs 18%) and independent or family living by 22% (71% vs 58%), and to decrease receipt of disability benefits by 36% (42% vs 66%) and hospital admissions per 1000 patient-years by 15% (249% vs 294%). CONCLUSIONS While these simulation results need to be confirmed empirically, they suggest that earlier use of LAI antipsychotics can meaningfully improve patient outcomes.

Abstract
The impact of initiatives aimed at reducing time in untreated psychosis during early-stage schizophrenia will be unknown for many years. Thus, we simulate the effect of earlier treatment entry and better antipsychotic drug adherence on schizophrenia-related hospitalizations, receipt of disability benefits, competitive employment, and independent/family living over a ten-year horizon. We predict that earlier treatment entry reduces hospitalizations by 12.6-14.4% and benefit receipt by 7.0-8.5%, while increasing independent/family living by 41.5-46% and employment by 42-58%. We predict larger gains if a pro-adherence intervention is also used. Our findings suggest substantial benefits of timely and consistent early schizophrenia care.

Abstract
Objective: Early initiation of antipsychotic treatment in schizophrenia is associated with improved outcomes. This study aimed to determine if initiation of long-acting injectable (LAI) antipsychotic treatment early in a new schizophrenia episode is associated with lower hospitalization rates and healthcare costs in a real-world setting. Methods: This retrospective (January 1, 2007-June 30, 2016) cohort analysis used claims from Truven Health Analytics MarketScan Commercial, Medicaid, and Medicare Supplemental databases. In adults ≥18 years with a new episode of schizophrenia, two mutually exclusive cohorts were identified based on time from first recorded schizophrenia diagnosis date to first date of LAI initiation (index date): ≤1 year (early initiators) and >1 year (late initiators). Logistic and general linear regression models were performed to estimate adjusted hospitalization rate and healthcare costs in a 1-year follow-up, controlling patient demographic and clinical characteristics, insurance type, baseline all-cause hospitalizations and ED visits, and baseline psychiatric medication use. Results: Of the subjects, 32% (n = 1388) initiated treatment early and 68% (n = 2978) initiated treatment later. In risk-adjusted models, all-cause hospitalization rates were 22.2% (95% CI = 19.9-24.6%) in early initiators and 26.9% (95% CI = 25.2-28.7%) in late initiators (p = .002). Of early initiators, 14.1% (95% CI = 12.3-16.1%) had a psychiatric hospitalization vs 19.2% (95% CI = 17.7-20.8%) of late initiators (p < .001). Adjusted psychiatric healthcare costs were significantly lower in early initiators compared with late initiators [mean (95% CI) = $21,545 (20,355-22,734) vs $24,132 (23,330-24,933)] (p < .001). Conclusions: LAI initiation within 1 year of a new schizophrenia episode led to lower hospitalization rates and healthcare costs compared with LAI initiation more than 1 year after a new episode.

Abstract
AIM To characterize the inpatient care received by individuals experiencing early psychotic episodes in an inner city hospital. METHOD Medical records of patients admitted between April 01, 2013, and March 31, 2015, to a psychiatric ward at an inner city hospital were retrospectively examined. Included in the study are patients who were 25 years of age or younger and were hospitalized for psychotic symptoms. Demographics and health service use were summarized using descriptive statistics. RESULTS A total of 73 inpatients (mean age = 22; males =78%; Caucasian = 41%) met the study inclusion criteria with a combined total of 102 care episodes and an average length of stay of 32.6 days. Monitoring of vital signs (VS) and mental status examinations (MSE) were performed in most care episodes although these were not performed regularly (daily VS checks-31%; MSE every nursing shift-18.6%). In 49% of the care episodes, patients were discharged on long-acting injectable antipsychotics. Even when indicated, not all care episodes had follow-up appointments (82.8%) in the community. The use of seclusion was higher in the wards (32%) than in the emergency department (21%), whereas the use of restraints was higher in the emergency department (16%) than in the wards (<1%). CONCLUSIONS There is wide variation in the rate at which various clinical care processes are performed and in the provision of inpatient care to younger adults experiencing episodes of early psychosis. Consistent standards of care are needed to reduce variations and improve treatment outcomes and experiences.

Abstract
Schizophrenia is a chronic syndrome involving different clinical dimensions, and causes significant disability with a negative impact on the quality of life of patients and their caregivers. Current guidelines for the treatment of schizophrenia focus on maximizing a patient's adaptive functioning and quality of life in a recovery-oriented approach that encourages active collaboration among patients, caregivers, and mental health professionals to design and manage a customized and comprehensive care plan. In the present study, a panel of experts (psychiatrists, psychologists, nurse, and social worker) gathered to review and explore the need for contemporary use of second-generation antipsychotic long-acting injectables (SGA LAIs) in "recovery-oriented" and "patient-centered" care of schizophrenia. Starting from the available data and from sharing personal attitudes and experiences, the panel selected three clinical dimensions considered useful in characterizing each patient: phase of disease, adherence to treatment, and level of functioning. For each clinical dimension, perspectives of patients and caregivers with regard to needs, expectations, and personal experiences were reviewed and the role of SGA LAIs in achieving shared goals examined. The experts concluded that from today's modern perspectives, SGA-LAIs may play an important role in breaking the spiral of desocialization and functional decline in schizophrenia, thus favoring the recovery process.

Abstract
OBJECTIVES The aim of this study is to provide an opinion paper reviewing the role of depot or long-acting injectable (LAI) antipsychotic medications, with comments on individual newer LAIs such aripiprazole maintena and paliperidone palmitate. In particular, we share our recent experience of using paliperidone three-monthly LAI. We also reflect on the associated benefits and potential harms of LAIs, and when they may be used. CONCLUSIONS LAI antipsychotics are an important and arguably under-utilised therapeutic option, particularly where medication adherence is a priority, and where an informed patient opts for this formulation. Paliperidone is the first three-monthly LAI antipsychotic, and as such represents a significant advance in the range of treatment choices.

Abstract
PURPOSE OF REVIEW Psychosis is a psychiatric condition that has significant overlap with neurologic disease. This article is intended to educate the neurologist on the psychiatric manifestations of psychosis and its evaluation, diagnosis, and treatment. How to differentiate a primary psychiatric cause of psychosis from psychosis secondary to a medical or neurologic condition is also reviewed. RECENT FINDINGS Current research in psychotic disorders has focused increasingly on negative symptoms and cognitive impairment in psychotic illness, as it is now recognized that these cause the greatest impact on functional deficits for patients. A number of new medications have also been introduced to target negative symptoms and cognitive deficits in psychotic illness. These have new implications in terms of treatment overlap with medications being prescribed by providers in psychiatry, neurology, and general practice. SUMMARY This article discusses the current methods for evaluating, diagnosing, and treating psychosis. Psychosis as a primary mental health disorder is a diagnosis of exclusion, as psychosis can be a direct symptom of underlying medical or neurologic disease. Delirium and dementia are the two most important disorders to rule out. This article will help readers be more prepared to assess and treat the patient with psychosis.

Abstract
BACKGROUND Outpatient facilities, such as community behavioral health organizations (CBHOs), play a critical role in the care of patients with serious mental illness, but there is a paucity of "real-world" patient outcomes data from this health care setting. Therefore, we conducted The Research and Evaluation of Antipsychotic Treatment in Community Behavioral Health Organizations, Outcomes (REACH-OUT) trial, a real-world, prospective, noninterventional observational study of patients with mental illness treated at CBHOs across the United States. We describe demographic and clinical characteristics, antipsychotic therapy (APT) treatment patterns, and health care resource utilization in patients with schizophrenia undergoing medical care as usual. METHODS This study enrolled adults with schizophrenia or bipolar I disorder who initiated APT treatment at various time points: 1) within 8 weeks of initiating risperidone long-acting injectables (RLAIs) or other APTs except paliperidone palmitate (PP), 2) after more than 24 weeks of continuous RLAI treatment, or 3) at any time after initiating PP LAI treatment (schizophrenia only). Study assessments were performed via participant interview, medical chart abstraction, and clinical survey at enrollment and at month 12. RESULTS A total of 1065 patients from 46 CBHOs were enrolled. Of these, 944 (88.6%) had a diagnosis of schizophrenia and 121 (11.4%) had bipolar I disorder. At enrollment, 599 (63.5%) of patients with schizophrenia were receiving RLAIs or PP LAI, 281 (29.8%) were receiving oral APTs, and 64 (6.8%) were receiving other injectable APTs. A number of differences in patient characteristics and outcomes were observed between patients in the LAI APT cohort and the oral APT cohort. CONCLUSION Descriptive analyses from this observational study suggest differences in the patient characteristics, treatment patterns, and clinical and economic outcomes among those with schizophrenia treated at CBHOs with LAI APT or oral APTs. Additional analyses will be conducted to delineate the impact of LAI APT versus oral APTs on patient outcomes. TRIAL REGISTRATION Clinical Trial Registry: NCT01181960 . Registered 12 August 2010.

Abstract
OBJECTIVE The present guidelines address the pharmacotherapy of schizophrenia in adults across different stages, phases, and symptom domains. METHOD Guidelines were developed using the ADAPTE process, which takes advantage of existing guidelines. Six guidelines were identified for adaptation, with recommendations extracted from each. For those specific to the pharmacotherapy of schizophrenia in adults, a working group selected between guidelines and recommendations to create an adapted guideline. RESULTS Recommendations can be categorized into 6 areas that include 1) first-episode schizophrenia, 2) acute exacerbation, 3) relapse prevention and maintenance treatment, 4) treatment-resistant schizophrenia, 5) clozapine-resistant schizophrenia, and 6) specific symptom domains. For each category, recommendations are made based on the available evidence, which is discussed and linked to other established guidelines. CONCLUSIONS In most cases, evidence-based recommendations are made that can be used to guide current clinical treatment and decision making. Notably, however, there is a paucity of established evidence to guide treatment decision making in the case of clozapine-resistant schizophrenia, a subsample that represents a sizable proportion of those with schizophrenia.

Abstract
Long acting injections (LAI) are an effective alternative mode of administration of antipsychotics, less commonly used in clinical practice. Gap in knowledge base is an important source of attitudinal bias. Current article is focused on reviewing the literature for the principles underlying the choice, initiation, maintenance, switch and termination of an LAI; historical, pharmacological and clinical factors implicating the rationale of using LAI against oral agents and older against newer LAIs. Evidences available in clinical and basic psychopharmacological researches are critically appraised, highlighting the lacunae in our understanding. It is endeavored to open the window for the studies to be carried forward in the future answering critical questions which could lay a stronger base for clinical utility of different LAIs. Thus, this article tries to acquaint clinicians with the translatable knowledge imparted from the research and riposte queries for the researchers to explore in relation to LAI.

[PMID: 27866695 DOI: 10.1016/j.schres.2016.11.010] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Revised: 11/06/2016] [Accepted: 11/09/2016] [Indexed: 01/07/2023]
Abstract
Recently, many authors highlighted the potential advantages of a broader prescription of long-acting injectable antipsychotics (LAIs) based on various assumptions, including favorable pharmacokinetic features. In this systematic review, data from randomized controlled trials comparing LAIs versus the oral formulation of the same antipsychotic were meta-analyzed in order to ascertain whether the route of administration may be associated with a different efficacy and tolerability profile. Of 21 included studies, 18 contributed to the meta-analysis, providing data for risperidone, olanzapine, aripiprazole, zuclopenthixol, fluphenazine and haloperidol. For all drugs, the number of dropouts for any reason (primary outcome) did not differ between the two formulations, except for a small effect in favor of LAI aripiprazole (2 comparisons; 986 patients; relative risk (RR) 0.78; 95% confidence interval (CI) 0.64 to 0.95). Similarly, no differences emerged in terms of dropouts for adverse events, extrapyramidal symptoms, prolactin increase (except for a small advantage for LAI risperidone), weight gain, non-response rate, relapse rate, and dropouts for inefficacy (except for a small advantage for oral olanzapine). Data on aripiprazole proved to be of high quality according to the GRADE approach (Grading of Recommendations, Assessment, Development and Evaluation), therefore we are confident that the effect estimate is close to the true effect. Data on risperidone were of moderate quality, while data on olanzapine, fluphenazine, zuclopenthixol and haloperidol were of low quality. In conclusion, there is no robust evidence to support doctors in choosing LAI instead of oral formulations in order to obtain better tolerability and efficacy.

Treatment Duration With Long-Acting Injectable Antipsychotics After In-hospital Initiation: A Retrospective Cohort Study. J Clin Psychopharmacol 2017; 37:250-254.

Abstract
PURPOSE Long-acting injectable (LAI) antipsychotics are recommended especially for patients with multiple admissions and poor adherence. The empirical basis of this strategy is a matter of debate. METHODS In a retrospective cohort study extending over 6 years, all patients admitted for inpatient treatment with a diagnosis of psychotic disorders according to International Statistical Classification of Diseases and Related Health Problems, 10th Revision (F2) were screened for treatment episodes with a new start of an LAI. Indication for LAI treatment was based primarily on previous medication default. All-cause discontinuation was used as a measure of treatment efficiency. Patients with early dropout (termination of LAI treatment within 6 months) were compared with patients with longer treatment (treatment >6 months) for sociodemographic and treatment variables using bivariate and multivariate analyses. RESULTS A total of 194 treatment episodes with new start of LAIs were identified. Almost one half dropped out within 6 months (early dropout: n = 95 [49%]; mean duration, 2.2 months). Termination of treatment was mainly due to patients' refusal to continue. However, almost a third of patients (61; 31.4%) had a treatment duration of more than 2 years. In a multivariate Cox regression model, longer treatment duration was associated with older age (P = 0.05), not being single (P = 0.04), fewer admissions during the year preceding the index episode (P = 0.02), and better ratings for adherence at the index episode (P = 0.03). CONCLUSIONS There are both more patients than expected leaving the treatment early and more patients than expected staying for long periods, even among patients with a history of poor adherence.

Abstract
AIMS Paliperidone palmitate 3-month (PP3M) represents a new long-acting injectable antipsychotic therapeutic option. This review aims: 1) to summarize available data relating to efficacy, safety, tolerability and costs of PP3M; 2) to describe hospitalization rate, occupational status, treatment preference, satisfaction, adherence and caregiver burden of patients with schizophrenia who participate in PP3M clinical trials; 3) to examine ethical implications, pros and cons of PP3M use and 4) to propose study designs to further assess PP3M. METHODS On August 21, 2017, a search on PubMed about PPM3, without any filter restriction, was conducted and all available records were analyzed. Records written in a language other than English were excluded. RESULTS Twenty-two records were included in this review: 6 reviews, 1 report, 4 pharmacokinetic studies, 2 cost-effectiveness analyses, 1 open-label clinical trial, 2 randomized controlled trials (RCTs), 5 studies based on these 2 RCTs and 1 observational study. DISCUSSION According to these last 9 studies, when compared with placebo, PP3M showed a longer time to relapse and good safety and tolerability profiles. Furthermore, when compared with paliperidone palmitate 1 month (PP1M), PP3M treatment showed: 1) non-inferiority in terms of efficacy, safety, tolerability, rate of hospitalization, symptomatic and functional remission, treatment preference and variations of the occupational status; 2) a longer time to relapse after treatment discontinuation and 3) a similar reduction of the caregiver burden. CONCLUSION PP3M is the only 3-monthly long-acting injectable antipsychotic available on the market. This makes it a unique option of treatment, which could be chosen both in early and advanced phases of illness. Nonetheless, longer naturalistic follow-up studies, two-arm head-to-head superiority trials and mirror studies, based on real-world samples of patients, are needed to further assess long-term safety and advantages of this new option of treatment and to define patients' sub-populations that would most beneficiate from it.

Abstract
Implementing the most suitable treatment strategies and making appropriate clinical decisions about individuals with a first episode of psychosis (FEP) is a complex and crucial task, with relevant impact in illness outcome. Treatment approaches in the early stages should go beyond choosing the right antipsychotic drug and should also address tractable factors influencing the risk of relapse. Effectiveness and likely metabolic and endocrine disturbances differ among second-generation antipsychotics (SGAs) and should guide the choice of the first-line treatment. Clinicians should be aware of the high risk of cardiovascular morbidity and mortality in schizophrenia patients, and therefore monitoring weight and metabolic changes across time is mandatory. Behavioral and counseling interventions might be partly effective in reducing weight gain and metabolic disturbances. Ziprasidone and aripiprazole have been described to be least commonly associated with weight gain or metabolic changes. In addition, some of the SGAs (risperidone, amisulpride, and paliperidone) have been associated with a significant increase of plasma prolactin levels. Overall, in cases of FEP, there should be a clear recommendation of using lower doses of the antipsychotic medication. If no or minimal clinical improvement is found after 2 weeks of treatment, such patients may benefit from a change or augmentation of treatment. Clinicians should provide accurate information to patients and relatives about the high risk of relapse if antipsychotics are discontinued, even if patients have been symptom free and functionally recovered on antipsychotic treatment for a lengthy period of time.

Safety and tolerability of long-acting injectable versus oral antipsychotics: A meta-analysis of randomized controlled studies comparing the same antipsychotics. Schizophr Res 2016; 176:220-230.

Abstract
OBJECTIVE We aimed to assess whether long-acting injectable antipsychotics (LAIs), which are initiated in a loading strategy or overlapping with oral antipsychotics (OAPs) and which cannot be stopped immediately, are associated with greater safety/tolerability issues than OAPs. METHOD Systematic review and meta-analysis of randomized controlled trials (RCTs) comparing LAIs and OAPs, including only LAI-OAP pairs of the same OAP (allowing oral risperidone and paliperidone as comparators for either risperidone or paliperidone LAI). Primary outcome was treatment discontinuation due to adverse events. Secondary outcomes included serious adverse events, death, ≥1 adverse event and individual adverse event rates. RESULTS Across 16 RCTs (n=4902, mean age=36.4years, males=65.8%, schizophrenia=99.1%) reporting on 119 adverse event outcomes, 55 (46.2%) adverse events were reported by ≥2 studies allowing a formal meta-analysis. Out of all 119 reported adverse events, LAIs and OAPs did not differ significantly regarding 115 (96.6%). LAIs were similar to OAPs regarding the frequency of treatment discontinuation due to adverse events, serious adverse events, all-cause death and death for reasons excluding accident or suicide. Compared to OAPs, LAIs were associated with significantly more akinesia, low-density lipoprotein cholesterol change and anxiety. Conversely, LAIs were associated with significantly lower prolactin change. CONCLUSION LAIs and OAPs did not differ on all serious and >90% of individual adverse events. However, more studies focusing on adverse event frequencies, severity and time course associated with LAI vs OAP formulations of the same antipsychotic are needed. Additionally, adverse events data for LAIs after stopping overlapping oral antipsychotic treatment are needed.

Abstract
AIM Results from clinical trials support the use of oral antipsychotics for treatment of early or first-episode psychosis in patients with schizophrenia. This paper will review literature on the advantages of early initiation of treatment for schizophrenia and the clinical benefits of early use of long-acting injectable antipsychotics (LAIs). METHOD A comprehensive literature review was conducted to identify published literature on the use of LAIs early in the treatment of schizophrenia. RESULTS Although there is a higher response rate to initial antipsychotic treatment for a first-episode of schizophrenia than with subsequent antipsychotic treatment, we have not effectively addressed this issue. Poor adherence to treatment is a primary cause of relapse and rehospitalization in subsequent years and was associated with higher relapse rates resulting in devastating effects and substantial economic burden. The costs of nonadherence were estimated to be $1.48 billion. Thus, a major challenge with the treatment of schizophrenia is changing poor adherence to persistence with antipsychotic therapy. LAIs are known to be at least as effective as oral antipsychotics for treating schizophrenia, and yet are underutilized. Further, LAIs address many of the problems associated with adherence to oral therapy. Recent evidence suggests that LAIs are effective for treating first-episode psychosis and for early initiation of treatment for schizophrenia. CONCLUSION Although consistent antipsychotic treatment represents a critical part of treatment, a person-centred approach to treating schizophrenia is essential for all aspects of care, including establishing and maintaining a therapeutic alliance, strengthening shared decision-making and adherence, and achieving long-lasting recovery.

Abstract
Schizophrenia and related disorders remain major disabling conditions, mainly due to antipsychotic treatment resistance and to relapses related to antipsychotic nonadherence. Treatment nonadherence rates are consistently high in long-term patients, but also in first-episode patients with schizophrenia. Long-acting injectable antipsychotics (LAIAs) were mainly developed to improve adherence to treatment and to reduce the rate of relapse and rehospitalization in schizophrenia due to treatment discontinuation. There is favorable clinical evidence, in terms of both efficacy and treatment adherence, that could support higher LAIA prescription rates, especially in patients in early phases of psychotic disorders. Several factors could be hindering wider use of LAIAs, mainly associated with perceptions and attitudes of patients, clinicians, and health managers or policy makers. The main aims of this review are (i) to summarize the existing data on the efficacy and tolerability of LAIAs compared with oral formulations in the management of schizophrenia and related disorders, focusing on the novel, second-generation LAIA options; (ii) to analyze the barriers that exist to the more widespread use of these formulations; and (iii) to discuss possible approaches to overcoming these barriers.

Abstract
Providing optimal care to patients with recent-onset psychosis can improve outcomes and reduce relapse. However, there is a lack of consistency of the implementation of guidelines for such patients across the Asia-Pacific region. We determined a pragmatic set of recommendations for use on a day-to-day basis to help provide optimal care at this crucial stage of illness. The recommendations were developed over a series of meetings by an international faculty of 15 experts from the Asia-Pacific region, Europe, and South Africa. A structured search of the PubMed database was conducted. This was further developed based on the faculty's clinical experience and knowledge of the literature into 10 key aspects of optimal care for patients during the first five years of a diagnosis of a psychotic disorder, with particular relevance to the Asia-Pacific region. Several common principles emerged: adherence to antipsychotic medications is crucial; substance abuse, psychiatric and medical comorbidities should be addressed; psychosocial interventions play a pivotal role; and family members can play a vital role in overall patient care. By following these recommendations, clinicians may improve outcomes for patients with recent-onset psychosis.

Abstract
AIM To assess the feasibility and effectiveness of depot antipsychotic (flupenthixol decanoate) combined with an assertive monitoring programme (AMP) in first-episode schizophrenia. METHODS This was a prospective, non-comparative, longitudinal study conducted over 12 months assessing patient acceptance, adherence, outcome in domains of psychopathology, functionality and quality of life, and tolerability. RESULTS Of 207 participants, 149 (72%) completed 12 months of treatment. Acceptance of and adherence to depot was good. Treatment response was achieved by 170 (82%) participants and remission by 124 (60%). Thirty-three (19%) responders relapsed and 10 (5%) participants met a priori criteria for treatment resistance. Treatment was generally well tolerated. CONCLUSIONS Combination of depot antipsychotic with an AMP may be an effective and safe intervention in early phases of schizophrenia, and may be particularly suitable for resource-constrained settings.

Abstract
AIM This study evaluated adherence to treatment, quality of life and subjective well-being in patients with psychosis treated with long-acting injectable risperidone. Subjects enrolled were part of a larger study where patients were observed in an adherence to treatment program of the University of Rome Tor Vergata. MATERIALS AND METHODS A total of 27 nonadherent patients (21 men, six women; mean age: 36.1 years; range: 23-63 years) were enrolled. Maximum observational period was 30 months. RESULTS A total of 12 patients were under treatment for 30 months (44.44%) but only nine had a valid 30-month follow up, while the remaining three patients initially treated at our unit continued long-acting risperidone at their local centre. Reductions of monthly mean values of Scale for the Assessment of Positive Symptoms (SAPS) [repeated measures analysis of variance (rm-ANOVA): p < 0.0001] and Scale for Assessment of Negative Symptoms (SANS) (p < 0.0001), increase of monthly mean values of Subjective Well-Being Under Neuroleptic Treatment Scale (SWN) (p < 0.0001) and Schizophrenia Quality of Life Scale (S-QoL) (p < 0.01) were observed. Significant differences with respect to SAPS baseline values from the sixth month, SANS baseline values from the seventh month, SWN baseline values from the eighth month, S-QoL baseline values from the eighteenth month were shown in post hoc tests. Reduction of SAPS mean values was associated with increase of SWN (p < 0.0001) and S-QoL (p < 0.0001) mean values as demonstrated by correlation analysis. The same inverse correlation was found between reduction of SANS mean values and increases of SWN (p < 0.0001) and S-QoL (p = 0.0001) mean values. CONCLUSIONS Long-term treatment with long-acting risperidone may be associated with improvement to adherence to therapy and quality of life. Patients may show improvement in psychopathological symptoms, subjective well-being and quality of life.

Abstract
INTRODUCTION This prospective study was performed to evaluate clinical efficacy and tolerability of olanzapine long-acting injection (OLZ-LAI) and the relation between OLZ plasma level (PL) and the clinical outcome in maintenance therapy of schizophrenia. MATERIAL AND METHODS Twenty-five chronic schizophrenic outpatients with age ranging from 18 to 65 years were included in this 9-month study. Patients were given a dosage of either 210 or 300 or 405 mg of OLZ-LAI every 28 days. Patients were evaluated at baseline and every four weeks by Brief Psychiatric Rating Scale (BPRS) and Positive and Negative Symptom Scale (PANSS); at the same time, PL of OLZ was determined. The metabolic profile (aspartate aminotransferase, alanine aminotransferase, high-density lipoprotein, low-density lipoprotein, total cholesterol, and glucose levels) was analyzed every two months. RESULTS BPRS and total PANSS showed a statistically significant improvement from T2 with a clinical stabilization of psychopathological picture. PL ranged from 4.0 to 78.9 ng/ml (mean 20.59 ng/ml ± 14.66 standard deviation). The coefficient of variation of PLs was related to clinical stabilization. No post-injection delirium sedation syndrome occurred. CONCLUSIONS Our data reveal the efficacy of OLZ-LAI in maintenance treatment of schizophrenia at lower dosages also in comparison with that of oral therapy. OLZ-LAI seems to be useful for guaranteeing constant PL of the drug. A lesser variation of PL was the most predictable factor associated with maintenance of clinical benefit.

Abstract
BACKGROUND AND OBJECTIVES Short-term studies focused on once-monthly paliperidone palmitate (PP) at doses of 25 mg eq, 50 mg eq, 75 mg eq, 100 mg eq, or 150 mg eq have shown its efficacy and tolerability in the treatment of schizophrenia patients. However, few open-label and long-term studies are available regarding this new pharmacological formulation. Thus, our main aim was to review the scientific evidence on efficacy, safety, tolerability, and preference of PP in these populations. METHOD Electronic searches were conducted by using PubMed and ISI Web of Knowledge databases. All relevant studies published from 2009 until January 2015 were included without any language restriction if patients met diagnostic criteria for schizophrenia, and adequate information on efficacy, safety, and tolerability of once-monthly PP was available. RESULTS Nineteen studies were identified irrespective of the study design and duration of the follow-up period. Randomized, double-blind, placebo-controlled trials found that schizophrenia patients receiving PP showed a significant improvement in psychotic symptoms and similar adverse events compared to placebo and suggested that all doses of PP were efficacious and well tolerated. Other studies demonstrated noninferiority of PP compared to risperidone long-acting injectable in recently diagnosed schizophrenia patients, chronically ill patients, as well as in acute and nonacute symptomatic schizophrenia patients, and a similar proportion of treatment-emergent adverse events between both groups were also noted. CONCLUSION Several studies have demonstrated that schizophrenia patients treated with PP show higher rates of improvement of psychotic symptoms compared to placebo, and similar efficacy and tolerability outcomes were noted when comparing PP to risperidone long-acting injectable or oral, paliperidone extended release.

Abstract
OBJECTIVE While atypical long-acting injectable antipsychotics (LAIs) offer the potential for increased adherence, access to medication poses challenges that may hinder their use. Janssen Connect * *Janssen Connect is a registered trade name of Janssen Scientific Affairs, LLC, Titusville, NJ, USA. (JC), a comprehensive information and assistance program, was designed to help patients who received a Janssen LAI initiate and maintain treatment after their health care professional (HCP) determined that the medication was the most clinically appropriate option. We conducted a formative and impact evaluation on early medication adherence of patients enrolled in JC and prescribed paliperidone palmitate. METHODS Using the program administrative files (December 2010-April 2014), 9354 patients whose HCP ordered paliperidone palmitate were included. Patient demographics, clinical characteristics, and request of JC program offerings were reported overall, and compared between patients requesting the injection center versus those who did not. Medication adherence based on the first 6 months of treatment while in the program and defined as achieving ≥80% proportion of days covered (PDC) was measured for patients receiving ≥2 paliperidone palmitate injections (n = 2659). Logistic models evaluated the association between requests for injection centers on medication adherence. RESULTS Mean age of program enrollees was 40.6 (standard deviation = 13.9 years), 59.3% were men, and 42.5% were Medicare covered. While in the program, 79.9% did not experience a medication gap of ≥7 weeks and 87.0% achieved adherence. Injection center request was associated with medication adherence (adjusted odds ratio (aOR) ≤5 months: 0.03; 95% confidence interval (CI): 0.02-0.05; ≥6 months: aOR: 4.16; 95% CI: 2.72-6.36). LIMITATIONS The data sources used were designed for program implementation and not for research purposes. CONCLUSIONS The high percentage of patients requesting injection center support and medication shipment in addition to other insurance-related program offerings signals the need for and value of a comprehensive support program for patients seeking LAI therapy. Providing patients with the option of alternative and more conveniently located injection centers may help them start and maintain their treatment.

Abstract
Treatment resistance, along with its sibling partial response, remains a common phenomenon in schizophrenia, complicating the disability burden inherent in the disease. Antipsychotic medications are the mainstay of treatment, and treatment resistance has mainly been defined in terms of poor response to antipsychotic medication. At the same time, clozapine, the most effective antipsychotic, remains underutilized at the expense of exposing patients to polypharmacy. We review known causes of disability in schizophrenia, how they impact various areas of everyday functioning, and discuss potential treatment options including but not limited to pharmacological approaches aimed at maximizing treatment response and reducing treatment resistance.

Abstract
The use of long-acting injectable antipsychotics (LAIs) in schizophrenia is usually restricted to patients in long-term treatment, who prefer them to oral antipsychotics, and to patients with multiple relapses who have a history of non-adherence. However, preliminary evidence from patients in the early phases of the disease suggest that second generation LAIs may be superior to second generation oral medications with regard to the control of negative symptoms and psychosocial functioning. Moreover, several studies have found that psychiatrists are generally reluctant to prescribe LAI antipsychotics and under-estimate their acceptability by patients. Key elements to take into account when offering a LAI in the early course of schizophrenia should include their potential superiority in allowing early detection of non-adherence and in reducing the number of rehospitalisations and relapses.

Abstract
Despite their widespread use, long-acting injectable (LAI) antipsychotics (APs) are often regarded with some negativity because of the assumption of punishment, control and insufficient evolution towards psychosocial development of patients. However, LAI APs have proved effective in schizophrenia and other severe psychotic disorders because they assure stable blood levels, leading to a reduction of the risk of relapse. Therapeutic opportunities have also arisen after introduction of newer, second-generation LAI APs in recent years. Newer LAI APs are more readily dosed optimally, may be better tolerated and are better suited to integrated rehabilitation programmes. This review outlines the older and newer LAI APs available for the treatment of schizophrenia, with considerations of past and present pharmacological and therapeutic issues. Traditional, evidence-based approaches to systematic reviews and randomized clinical trials are of limited utility in this area so this paper's blending of experimental trials with observational research is particularly appropriate and effective.

Abstract
OBJECTIVES The objective of this study was to investigate attitudinal themes to antipsychotic long-acting injections (LAIs) in patients in an early intervention team (EIT). METHODS Interviews were carried out with outpatients purposively sampled from an EIT to represent patients currently prescribed antipsychotic LAIs, oral antipsychotics and those not prescribed antipsychotic medication. Interviews were conducted and analysed according to grounded theory. Recruitment stopped when saturation of themes was reached. RESULTS Interviews from 11 patients were analysed (median age 24 years). Attitudes to LAIs were condensed into three key categories: therapeutic alliance and the psychiatrists' recommendation of antipsychotic medication; patients' knowledge and beliefs about LAIs; and patients' views regarding the appropriateness of LAIs. Participants valued their psychiatrist's recommendation as to the most appropriate antipsychotic. Attitudes to LAIs varied but were most positive among those currently receiving a LAI. Among those not prescribed LAIs, some were open to considering a LAI if their clinician recommended it but others were opposed to such treatment and preferred tables. There was a lack of awareness of LAIs as a treatment option among those not prescribed a LAI. Delay in being offered a LAI was reported in the group currently prescribed a LAI. Several participants associated oral antipsychotics, LAIs and mental illness with stigma. Some not prescribed a LAI had misperceptions about the nature of this treatment. Participants regarded the advantages of LAIs as convenience and avoiding forgetting to take tablets, while disadvantages included injection pain, fear of needles and coercion. CONCLUSION Lack of knowledge, misperceptions and stigma related to LAIs and other treatment options should be addressed by providing patients with accurate information. This will facilitate patients being involved in choices about treatment, and should they decide to accept medication, which drug and formulation is most appropriate for their needs. Clinicians should avoid making assumptions about patients' attitudes to LAIs; attitudes vary but some early intervention patients not prescribed LAIs are open to considering this treatment. Antipsychotic prescribing should result from a shared decision-making process in which clinicians and patients openly discuss the pros and cons of different formulations and drugs. The themes identified in this qualitative study require further exploration using quantitative methodology.

Abstract
OBJECTIVE The current study compares the compliance rates of patients on depot who were on Community Treatment Orders with those who were not on such Order with a view to objectively quantify the effect of Community Treatment Orders on depot antipsychotics medication compliance. METHODS "Day difference" measurements between the scheduled depot data and the administered date were collected for both voluntary and involuntary patients receiving depot medication at the same community clinic over a 6-month period. RESULTS The results demonstrated a trend for greater compliance to depot medications by those not on a Community Treatment Order compared with those who were, but there was no statistically significant difference between the two groups. CONCLUSIONS The current study highlighted that while Community Treatment Order may be a reasonable short-term tool to encourage patients' compliance at an early treatment stage, ongoing effort should be put into improving patients' attitude towards depot medications to ensure a better long-term outcome for individuals with schizophrenia.

Abstract
BACKGROUND A considerable proportion of patients suffering from schizophrenia show suboptimal responses to oral antipsychotics due to inadequate adherence. Hence, they are likely to benefit from switching to a long-acting injectable formulation. These post hoc analyses assessed the clinical effects of switching to olanzapine long-acting injection (OLAI) from either oral olanzapine (OLZ) or other antipsychotics (non-OLZ). METHODS Post hoc analyses were done based on two randomized studies (one short-term, one long-term) conducted in patients suffering from schizophrenia and treated with OLAI. The short-term study was an 8-week placebo-controlled, double-blind trial in acute patients, and the long-term study was a 2-year, oral olanzapine-controlled, open-label, follow-up of stabilized outpatients. RESULTS These analyses used data from 62 OLAI-treated patients (12 switched from OLZ, 50 from non-OLZ) from the short-term study and 190 OLAI-treated patients (56 switched from OLZ, 134 from non-OLZ) from the long-term study. Kaplan-Meier survival analyses of time to all-cause discontinuation of OLAI treatment did not differ significantly between OLZ and non-OLZ patients in the short-term study (P=0.209) or long-term study (P=0.448). Similarly, the proportions of OLZ and non-OLZ patients that discontinued OLAI were not statistically different in the short-term (16.7% versus 36.0%, respectively; P=0.198) or long-term (57.1% versus 47.8% respectively; P=0.238) studies. In the short-term study, no significant differences were detected between the patient groups in mean change in Positive and Negative Syndrome Scale (PANSS) total score (-13.4 OLZ versus -20.8 non-OLZ; P=0.166). In the long-term study, mean change in PANSS total score (3.9 OLZ versus -3.6 non-OLZ; P=0.008) was significantly different between the non-OLZ and OLZ groups. Rates of treatment-emergent adverse events were similar in OLZ and non-OLZ groups per study. CONCLUSION These post hoc analyses suggest that no significant differences in clinical effectiveness were seen after switching from non-OLZ or OLZ to OLAI. However, these findings should be interpreted with care, due to small sample sizes and differences in patients' clinical profiles.

Abstract
BACKGROUND Schizophrenia spectrum disorders are severe mental illnesses which often result in significant distress and disability. Attempts have been made to prospectively identify and treat young people viewed as at high risk of impending nonaffective psychosis. Once a schizophrenia spectrum disorder has developed, prompt identification and management is required. METHODS This article reviews the literature relating to the assessment and management of 'at-risk mental states' (ARMS) and the treatment of schizophrenia spectrum disorders in children and adolescents. A systematic search of the literature was undertaken using EMBASE, MEDLINE, PsycINFO databases for the period January 1970-December 2012. RESULTS Evidence suggests that young people fulfilling the ARMS criteria are at high risk of adverse mental health outcomes but that the majority do not develop nonaffective psychosis over the medium term. Although clinical trial findings have been inconsistent, psychosocial approaches, such as cognitive behaviour therapy, may reduce the risk of transition to psychosis and improve some symptoms, at least over the short term. The effectiveness of psychotropic medication for the ARMS is uncertain although there is accumulating evidence for potential adverse effects of antipsychotic medication, even at low dose, in this population. For the schizophrenias, clinical trial findings suggest that, as in adults, antipsychotics should be selected on the basis of side-effect profile although clozapine may be helpful in treatment refractory illness. There are almost no studies of psychosocial treatments for schizophrenia in young people under 18, and some caution must be exercised when extrapolating the findings of adult studies to younger individuals. CONCLUSIONS A stepped care approach to the ARMS in young people represents a plausible potential management approach for those at high risk of serious mental health problems. However, predictive models currently lack precision and should focus on accurately identifying those at high risk for a variety of poor outcomes who may benefit most from intervention. There is also an urgent need for age-specific research in the area of psychosocial treatments for children and adolescents with schizophrenia.

Abstract
Schizophrenia is a debilitating chronic disease that requires lifelong medical care and supervision. Even with treatment, the majority of patients relapse within 5 years, and suicide may occur in up to 10% of patients. Poor adherence to oral antipsychotics is the most common cause of relapse. The discontinuation rate for oral antipsychotics in schizophrenia ranges from 26% to 44%, and as many as two-thirds of patients are at least partially nonadherent, resulting in increased risk of hospitalization. A very helpful approach to improve adherence in schizophrenia is the use of long-acting injectable (LAI) antipsychotics, although only a minority of patients receive these. Reasons for underutilization may include negative attitudes, perceptions, and beliefs of both patients and health care professionals. Research shows, however, significant improvements in adherence with LAIs compared with oral drugs, and this is accompanied by lower rates of discontinuation, relapse, and hospitalization. In addition, LAIs are associated with better functioning, quality of life, and patient satisfaction. A need exists to encourage broader LAI use, especially among patients with a history of nonadherence with oral antipsychotics. This paper reviews the impact of nonadherence with antipsychotic drug therapy overall, as well as specific outcomes of the schizophrenia patient, and highlights the potential benefits of LAIs.
