Abstract
BACKGROUND The Patient Journey Project aims to collect real-world experiences on schizophrenia management in clinical practice throughout all the phases of the disorder, highlighting virtuous paths, challenges and unmet needs. METHODS A 60-item survey was co-designed with all the stakeholders (clinicians, expert patients and caregivers) involved in the patient's journey, focusing on three areas: early detection and management, acute phase management and long-term management/continuity of care. For each statement, the respondents expressed their consensus on the importance and the degree of implementation in clinical practice. The respondents included heads of the Mental Health Services (MHSs) in the Lombardy region, Italy. RESULTS For early diagnosis and management, a strong consensus was found; however, the implementation degree was moderate-to-good. For acute phase management, a strong consensus and a good level of implementation were found. For long-term management/continuity of care, a strong consensus was found, but the implementation level was slightly above the cut-off, with 44.4% of the statements being rated as only moderately implemented. Overall, the survey showed a strong consensus and a good level of implementation. CONCLUSIONS The survey offered an updated evaluation of the priority intervention areas for MHSs and highlighted the current limitations. Particularly, early phases and chronicity management should be further implemented to improve the patient journey of schizophrenia patients.

Abstract
OBJECTIVES This observational retrospective real-world study examined changes in healthcare resource utilization (HCRU) pre- and post-initiation of aripiprazole once-monthly (AOM 400) in patients with schizophrenia or bipolar I disorder. METHODS Electronic health record-derived, de-identified data from the NeuroBlu Database (2013-2020) were used to identify patients ≥18 years with schizophrenia (n = 222) or bipolar I disorder (n = 129) who were prescribed AOM 400, and had visit data within 3, 6, 9, or 12 months pre- and post-initial AOM 400 prescription. Rates of inpatient hospitalization, emergency department visits, inpatient readmissions, and average length of stay were examined and compared over 3, 6, 9, and 12 months pre-/post-AOM 400 using a McNemar test. RESULTS Statistically significant differences were seen in both schizophrenia and bipolar I disorder patient cohorts pre- and post-AOM 400 in inpatient hospitalization rates (p < .001 all time points, both cohorts) and 30-day readmission per patient rates (p < .001 all time points, both cohorts). Statistically significant improvement in mean length of stay was observed in both cohorts at all time points, except for at six months in patients with schizophrenia. Emergency department visit rates were significantly lower after AOM 400 initiation for both cohorts at all time points (p < .001). CONCLUSIONS A reduction in the rate of hospitalizations, emergency department visits, 30-day readmissions, and average length-of-stay was observed for patients diagnosed with either schizophrenia or bipolar I disorder, which suggests a positive effect of AOM 400 treatment on HCRU outcomes and is supportive of earlier analyses from different data sources.

Abstract
Introduction Social determinants of health (SDOH) affect outcomes of people living with psychiatric disorders, including substance use disorders. As experts in medication optimization, pharmacists play a vital role in identifying and addressing medication-related problems associated with SDOH. However, there is a paucity of literature on how pharmacists can be part of the solution. Objective The purpose of this article is to provide a narrative review and commentary on the intersection between SDOH, medication-related outcomes in people living with psychiatric disorders, and the role of pharmacists in addressing them. Method The American Association of Psychiatric Pharmacists appointed an expert panel to research the issue, identify barriers, and develop a framework for including pharmacists in addressing medication therapy problems associated with SDOH in people with psychiatric disorders. The panel used Healthy People 2030 as the framework and sought input from public health officials to propose solutions for their commentary. Results We identified potential connections between SDOH and their impact on medication use in people with psychiatric disorders. We provide examples of how comprehensive medication management can afford opportunities for pharmacists to mitigate medication-related problems associated with SDOH. Conclusion Public health officials should be aware of the vital role that pharmacists play in addressing medication therapy problems associated with SDOH to improve health outcomes and to incorporate them in health promotion programs.

Abstract
OBJECTIVES To describe, in a naturalistic setting, the impact of the early use of LAI-AP on functional outcomes of early psychosis patients as compared to oral antipsychotics (OAP). METHODS Longitudinal prospective 3-year naturalistic study of all consecutive admissions (n = 416) to two Early intervention services (EIS) for psychosis comparing baseline characteristics and the evolution of global functioning, occupation (work and studies), and living arrangements autonomy according to the route of administration of the antipsychotic medication. The cohort was divided into four groups: LAI-AP first (started on LAI-AP and later received OAP), OAP first, LAI-AP only, and OAP only. RESULTS Global assessment of functioning (GAF) improved in all groups, but our mixed-effect model did not show any significant association between the route of administration and the GAF outcome. The LAI-AP only group was significantly less likely to have extreme residential instability at 3 years than the other groups despite its highest proportion of homeless youth and their poor prognostic factors at baseline. CONCLUSIONS Our naturalistic study suggests a significant protective effect of LAI-AP on extreme residential instability for the most vulnerable patients, but no impact of the first AP administration route on other functional outcomes was observed at 3 years of follow-up. Key pointsLong-acting injectable antipsychotics seem promising to avoid extreme residential instability in early psychosis.Global assessment of functioning (GAF) improved in all groups.There was no significant association between the first route of administration and global functionning.

The effect of long-acting injectable antipsychotic medications compared with oral antipsychotic medications among people with schizophrenia: A systematic review and meta-analysis. Int J Ment Health Nurs 2022; 31:469-535.

Abstract
Long-acting injectable (LAI) antipsychotic medications may be an important modality of reducing costs, improving symptoms, and fostering quality of life outcomes for those with schizophrenia. Our objective was to systematically review and conduct a meta-analysis of the effectiveness of LAIs compared with oral antipsychotics on medication adherence, symptom remission/relapse, rehospitalization, outpatient visits, emergency department visits, healthcare costs, and social functioning. We performed a systematic search of PsycInfo, CINAHL, PubMed, and Scopus databases to examine studies meeting inclusion criteria prior to August 30th, 2020. Randomized controlled trials, retrospective studies, prospective studies among people with schizophrenia with at least 6-month follow-up data were obtained. Overall effect sizes and associated 95% confidence intervals (CI) were estimated with random-effects modeling. We found 75 articles meeting our inclusion criteria, including 341 730 individuals with schizophrenia. Systematic review results indicated that LAIs compared with orals improved medication adherence (25/29 studies), symptom remission/relapse (10/18 studies), rehospitalizations (26/49 studies), emergency department visits (9/17 studies), medical costs (11/15 studies), and social functioning (5/9 studies); however, LAIs also increased outpatient visits (7/16 studies) and pharmacy costs (10/10 studies). Meta-analytic results of studies with similar outcome measures did not find differences between LAIs and orals in respect to outcomes, except lowering emergency department visits and increasing pharmacy costs. The differences between the results of the narrative synthesis and the meta-analyses were possibly because of the low availability of studies with similar outcomes in the pooled analyses. Our overall results suggest that LAIs are at least comparable to orals in supporting important healthcare outcomes for those with schizophrenia. These findings support clinical practice in encouraging providers to prescribe LAIs when indicated.

Healthcare resource utilization and costs before and after long-acting injectable antipsychotic initiation in commercially insured young adults with schizophrenia. BMC Psychiatry 2022; 22:250. [PMID: 35395757 PMCID: PMC8994268 DOI: 10.1186/s12888-022-03895-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 03/14/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Long-acting injectable (LAI) antipsychotics use is associated with improved adherence which can reduce the rate of relapse, hospitalization, and associated costs in patients with schizophrenia. Young adults could be at higher risk of poor adherence, hence use of LAI in this population may offer a benefit but the evidence is limited. This study aimed to compare clinical and economic outcomes before and after the initiation of LAI antipsychotics in commercially insured young adults (18-35 years of age) with schizophrenia. METHODS A retrospective claims data study was conducted using the data from the IBM MarketScan® Commercial Claims and Encounters (CCAE) Database. Patients with a continuous enrollment of at least 1-year before and 1-year after the first observed schizophrenia diagnosis (index date) and with the use of ≥1 typical or atypical LAI antipsychotic during the post-index follow-up period were included. A pre-post analysis was conducted to compare relapse rates, healthcare resource utilization, and costs before (from index date to LAI initiation) and after LAI initiation (to end of follow up). RESULTS A total of 2222 patients who initiated LAIs after an index schizophrenia diagnosis were identified. The per patient per month (PPPM) composite relapse event rate (0.109 pre-LAI to 0.073 post-LAI) and hospitalization rate (0.091 to 0.058), all-cause inpatient visits (0.231 to 0.119), and length of stay (2.694 to 1.092 days) significantly decreased from before LAI initiation to after LAI initiation with similar trends seen for mental health and schizophrenia-related measures (all significant; P < 0.0001). All-cause total costs ($4898 to $3078 PPPM) were also decreased after LAI initiation, with similar trends seen for mental health and schizophrenia-related costs (all significant; P < 0.0001). Although medication costs were higher post-LAI period ($311 to $542 PPPM), the cost increase was substantially offset by the decreased costs associated with total healthcare costs. CONCLUSIONS Treatment with LAI antipsychotics was associated with a decrease in relapse event rate, healthcare resource utilization, and costs after LAI initiation compared to before LAI initiation in commercially insured young adults with schizophrenia. Treatment with LAIs in young adults with schizophrenia is potentially associated with significant cost savings to commercial payers.

Abstract
BACKGROUND Partial adherence to antipsychotics is the most common cause of relapses and rehospitalization in patients with schizophrenia (SZ), leading to higher health care costs and psychosocial disability. The use of long-acting injectable (LAI) antipsychotics may improve therapeutic continuity and adherence to treatment. OBJECTIVE To assess the effectiveness of switching from oral antipsychotics (OAs) to long-acting antipsychotics. METHODS This 1-year mirror-image study evaluated the effect of switching from OAs to LAIs on the reduction of psychiatric hospitalizations and the improvement of global functioning in patients with schizophrenia. Differences in outcomes between second-generation (SGA) LAIs and first-generation (FGA) LAIs were also analyzed. RESULTS In all, 166 patients were included: 32.5% treated by FGA-LAIs and 67.5% by SGA-LAIs. There was an overall reduction of 71% in the average number of hospital admissions and an overall improvement of 29.3% in the Global Assessment of Functioning (GAF) score between the previous 12 months and the 12 months following the switching to LAIs. Patients who switched to SGA-LAIs had no significant differences in hospitalization occurrences but a significant improvement in GAF scores when compared with patients who switched to FGA-LAIs. CONCLUSION Our results suggest that using LAIs could be the most adequate treatment choice for SZ patients with a high risk of relapse and low adherence rate. Patients with poorer social functioning may be ideal candidates for SGA-LAIs treatment. Our findings may be of particular interest from a clinical and health care management perspective.

Abstract
It is essential to monitor pharmacological treatment for schizophrenic outpatients regularly in clinical practice. Especially in China, the situation of common prescribing patterns remains unclear. The objective of this study is to reveal real-world treatment prescription patterns of antipsychotics for schizophrenia patients in a representative large tertiary hospital in China.This study is a cross-sectional observational analysis of outpatients with schizophrenia in a large tertiary psychiatric hospital in Beijing, China, from May 11th to 24th, 2019. Data on subjects' socio-demographic and clinical characteristics, prescriptions of psychotropic drugs were collected from the electronic medical record (EMR) system with a standardized protocol. A multivariate analysis was performed to explore the potential association between antipsychotics treatments and subjects' characteristics.Of the 1940 patients included in this study, only 1470 (75.77%) patients were prescribed antipsychotic medications. 1228 (83.53%) patients were prescribed second-generation antipsychotics (SGAs), 202 (13.74%) patients were treated only with first-generation antipsychotics (FGAs), 40 (2.72%) were prescribed both SGAs and FGAs. The proportion of single SGAs prescriptions was significantly higher than that of single FGAs antipsychotics in each course of monotherapy group, especially among patients with the course less than 2 years (96.08%). Risperidone was most frequently prescribed antipsychotic medication during the study (29.86%, 439 out of 1470). Intermediate-acting sedative benzodiazepines were the most commonly co-prescribed psychotropic class at 23.66%. Long-acting injectable antipsychotics (LAIs) could be the prescribing trend in clinics. Disease course, self-paying cost and LAI antipsychotic use were independently associated with antipsychotics treatments.Second-generation antipsychotics showed domination in prescriptions. More concerns should be paid with concomitant psychiatric medications in clinics.

Abstract
Over the past 50 years, drug delivery breakthroughs have enabled the approval of several important medicines. Often, this path starts with innovation from academic collaborations amongst biologists, chemists, and engineers, followed by the formation of a start-up company driving clinical translation and approval. An early wave featured injectable (i.e., intramuscular, subcutaneous) biodegradable polymeric microspheres to control drug release profiles for peptides and small molecules (e.g., Lupron Depot®, Risperdal Consta®). With these early successes for microspheres, research shifted to exploring systemic delivery by intravenous injection, which required smaller particle sizes and modified surface properties (e.g., PEGylation) to enable long circulation times. These new innovations resulted in the nanoparticle medicines Doxil® and Abraxane®, designed to improve the therapeutic index of cytotoxic cancer agents by decreasing systemic exposure and delivering more drug to tumors. Very recently, the first siRNA lipid nanoparticle medicine, Patisiran (Onpattro®), was approved for treating hereditary transthyretin-mediated amyloidosis. In this inspirational note, we will highlight the technological evolution of drug delivery from micro- to nano-, citing some of the approved medicines demonstrating the significant impact of the drug delivery field in treating many diseases.

Abstract
Although approximately 20% of adults in the United States experience a mental health condition annually, there continues to be a gap in the provision of care because of a shortage of behavioral health providers. The National Council for Behavioral Health Medical Director Institute has recommended that the number of board-certified psychiatric pharmacists (BCPPs), who are clinical pharmacists with advanced specialized training and experience in the treatment of patients with psychiatric and substance use disorders, be expanded to help meet this need. Although BCPPs currently assist in expanding care access, improving medication-related outcomes, and reducing health care costs by working collaboratively with physicians and other health care providers, BCPPs are often underutilized. This lack of utilization results in lost opportunity to better address the needs of persons with psychiatric or substance use disorders and to meet these needs in a timely manner. Here, the authors bring attention to five key areas-opioid use disorder, antipsychotic use among children, long-acting injectable antipsychotics, clozapine use, and transitions of care and care coordination-in which BCPPs, along with other pharmacists, provide evidence-based care and could be more extensively used as a collaborative solution to the mental health and substance use disorder crisis in the United States.

Abstract
This article presents the evaluation of diblock and triblock poly(ethylene glycol)-b-poly(1,3-trimethylene carbonate) amphiphilic copolymers (PEG-PTMCs) as excipients for the formulation of long-acting injectables (LAIs). Copolymers were successfully synthesised through bulk ring-opening polymerisation. The concomitant formation of PTMC homopolymer could not be avoided irrespective of the catalyst amount, but the by-product could easily be removed by gel chromatography. Pure PEG-PTMCs undergo faster erosion in vivo than their corresponding homopolymer. Furthermore, these copolymers show outstanding stability compared to their polyester analogues when formulated with amine-containing reactive drugs, which makes them particularly suitable as LAIs for the sustained release of drugs susceptible to acylation.

Abstract
Schizophrenia Spectrum Disorder (SSD) is a chronic psychiatric disorder with a modest treatment outcome. In addition, relapses are commonplace. Here, we sought to identify factors that predict relapse latency and frequency. To this end, we retrospectively analyzed data for individuals with SSD. Medical records of 401 individuals with SSD were analyzed (mean age: 25.51 years; 63.6% males) covering a five-year period. Univariate and multivariate Penalized Likelihood Models with Shared Log-Normal Frailty were used to determine the correlation between discharge time and relapse and to identify risk factors. A total of 683 relapses were observed in males, and 422 relapses in females. The Relapse Hazard Ratio (RHR) decreased with age (RHR = 0.99, CI: (0.98–0.998)) and with participants’ adherence to pharmacological treatment (HR = 0.71, CI: 0.58–0.86). In contrast, RHR increased with a history of suicide attempts (HR = 1.32, CI: 1.09–1.60), and a gradual compared to a sudden onset of disease (HR = 1.45, CI: 1.02–2.05). Gender was not predictive. Data indicate that preventive and therapeutic interventions may be particularly important for individuals who are younger at disease onset, have a history of suicide attempts, have experienced a gradual onset of disease, and have difficulties adhering to medication.

Real-World Evidence of the Clinical and Economic Impact of Long-Acting Injectable Versus Oral Antipsychotics Among Patients with Schizophrenia in the United States: A Systematic Review and Meta-Analysis. CNS Drugs 2021; 35:469-481. [PMID: 33909272 PMCID: PMC8144083 DOI: 10.1007/s40263-021-00815-y] [Citation(s) in RCA: 45] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/29/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Long-acting injectable (LAI) antipsychotics, compared with oral antipsychotics (OA), have been found to significantly improve patient outcomes, including reduced hospitalizations and emergency room (ER) admissions and increased medication adherence among adult patients with schizophrenia. In turn, the clinical benefits achieved may translate into lower economic burden. Real-world evidence of the comparative effectiveness of LAI is needed to understand the potential benefits of LAI outside of the context of clinical trials. This study aimed to provide a comprehensive synthesis of recent published real-world studies comparing healthcare utilization, costs, and adherence between patients with schizophrenia treated with LAI versus OA in the United States. METHODS In this systematic literature review, MEDLINE® was searched for peer-reviewed, real-world studies (i.e., retrospective or pragmatic designs) published in English between January 1, 2010 and February 10, 2020. Comparative studies reporting hospitalizations, ER admissions, healthcare costs, or medication adherence (measured by proportion of days covered [PDC]) in adults with schizophrenia treated with LAI versus OA (or pre- vs post-LAI initiation) in the United States were retained. Random effects meta-analyses were conducted among eligible studies to evaluate the association of LAI versus OA use on hospitalizations, ER admissions, healthcare costs, and treatment adherence. A sensitivity analysis among the subset of studies that compared OA with paliperidone palmitate once monthly (PP1M), specifically, was conducted. RESULTS A total of 1083 articles were identified by the electronic literature search, and two publications were manually added subsequently. Among the 57 publications meeting the inclusion criteria, 25 provided sufficient information for inclusion in the meta-analyses. Compared with patients treated with OA, patients initiated on LAI had lower odds of hospitalization (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.54-0.71, n = 7), fewer hospitalizations (incidence rate ratio [IRR] [95% CI] 0.75 [0.65-0.88], n = 9), and fewer ER admissions (IRR [95% CI] 0.86 [0.77-0.97], n = 6). The initiation of LAI was associated with higher per-patient-per-year (PPPY) pharmacy costs (mean difference [MD] [95% CI] $5603 [3799-7407], n = 6), which was offset by lower PPPY medical costs (MD [95% CI] - $5404 [- 7745 to - 3064], n = 6), resulting in no significant net difference in PPPY total all-cause healthcare costs between patients treated with LAI and those treated with OA (MD [95% CI] $327 [- 1565 to 2219], n = 7). Patients initiated on LAI also had higher odds of being adherent to their medication (PDC ≥ 80%; OR [95% CI] 1.89 [1.52-2.35], n = 9). A sensitivity analysis on a subset of publications evaluating PP1M found results similar to those of the main analysis conducted at the LAI class level. CONCLUSIONS Based on multiple studies with varying sub-types of patient populations with schizophrenia in the United States published in the last decade, this meta-analysis demonstrated that LAI antipsychotics were associated with improved medication adherence and significant clinical benefit such as reduced hospitalizations and ER admissions compared with OA. The lower medical costs offset the higher pharmacy costs, resulting in a non-significant difference in total healthcare costs. Taken together, these findings provide strong evidence on the clinical and economic benefits of LAI compared with OA for the treatment of schizophrenia in the real world.

Abstract
BACKGROUND Paliperidone palmitate is a long-acting, second-generation antipsychotic (SGA) indicated for the treatment of acute exacerbations and maintenance treatment of adults with schizophrenia. This study addressed the response to paliperidone palmitate in Latin American patients with acute symptoms and recently diagnosed schizophrenia. OBJECTIVE Explore the efficacy and tolerability of paliperidone palmitate administered once a month for 4 months in patients with acute phase and recent diagnosis (within 1-6 years) of schizophrenia in 3 Latin American countries. METHODS This was a non-randomized, open-label, multicenter study with paliperidone palmitate injected intramuscularly in the deltoid muscle at an initial loading dose of 150 mg eq. (234 mg) on day 1 and 100 mg eq. (156 mg) on day 8 (± 4 days). The recommended maintenance dose was 75 mg eq. (117 mg) from day 36 to day 92. Efficacy was evaluated with PANSS and CGI-S. The last observation carried forward (LOCF) was used for efficacy analysis for imputation of missing data; no adjustments were made for multiplicity. Adverse events were evaluated during treatment. RESULTS The patient retention rate was 84.0% (144 patients received study drug; 121 finished the study). The percentage of patients with a reduction of at least 30% in PANSS total score compared to baseline gradually increased during the study, and at the end, 78.4% of patients showed response. The PANSS total score and CGI-S scores decreased significantly from baseline to LOCF endpoint (P <0.0001 for both); significant reduction in PANSS total score was observed at day 8 and persisted to the end of the study. Most common adverse events were muscle rigidity (11.8%), akathisia (11.1%), injection-site pain (7.6%), weight gain (7.6%), and insomnia (7.6%). CONCLUSION Paliperidone palmitate was efficacious in Latin American patients studied with an acute exacerbation and recent diagnosis of schizophrenia, and no new safety signals were identified.

Abstract
PURPOSE/BACKGROUND Despite proven benefits of long-acting injectables (LAIs), these are frequently underused by the psychiatrists. Accordingly, this study aimed to explore the perceptions of psychiatrists toward the use of LAI antipsychotics in their routine clinical practice. METHODS/PROCEDURE An online e-mail survey was conducted by using Survey Monkey platform. RESULTS A total of 622 psychiatrists with a mean age of 41 years who were in psychiatric practice for approximately 14 years participated in the survey. Participants reported using LAI, mainly for patients with schizophrenia, with LAI prescribed to approximately one-tenth (9.30%) of their patients in acute phase of illness and in one-fifth (18.42%) of patients in stabilization/stable phase. Fluphenazine decanoate (32.7%) was the most commonly used LAI followed by flupenthixol decanoate (19.5%), haloperidol decanoate (17.8%), and olanzapine pamoate (11.1%). The most common reasons for starting LAI were history of medication (100%) and treatment (80.5%) nonadherence, followed by having frequent relapses/exacerbations of symptoms (54.8%). Overall, more than half of the participants felt the level of acceptance of LAI among patients offered to be quite reasonable (54.3%), and mostly, LAIs were used as combination therapy with oral antipsychotics (73.6%). Despite all these, approximately three-fifths (59%) of the participants reported that they underuse LAI to a certain extent, with most common reasons that deter them from using LAI being the cost (55.45%), lack of interest of patients in receiving LAI (42.9%), lack of regular availability (41.3%), and patients being scared of receiving injectables (41.2%). CONCLUSIONS/IMPLICATIONS The LAI antipsychotics despite having several benefits are still underused by a substantial proportion of practicing psychiatrists.

Abstract
Introduction Antipsychotics improve symptoms associated with schizophrenia and bipolar disorder. To improve medication adherence and decrease the need for hospitalization, many antipsychotics have been developed into long-acting injectable (LAI) formulations. Though mirror-image studies have demonstrated significantly decreased hospitalization rates with LAI use, there is limited data when suboptimal use parameters are present. Methods A retrospective chart review was conducted on patients who were administered aripiprazole monohydrate long-acting injectable (AM-LAI) in an adult mental health unit. Demographics and AM-LAI use parameters were analyzed descriptively. Endpoints compared the days between encounters pre and post AM-LAI administration and number of inpatient encounters between the 180 days pre and post AM-LAI administration. Effects of AM-LAI on inpatient encounters were analyzed using a Wilcoxon signed rank test with an alpha set to <0.05 for significance. Results Fifty-eight patients met inclusion criteria. Mean (± SD) age was 39.4 (11.4) years with 55.2% of the sample male. Most patients were diagnosed with schizophrenia or unspecified psychotic disorder and admitted involuntarily. The mean number of days from last admission to the date of initial AM-LAI administration was 109.3 (75.2), compared with 131.3 (69.8) days to next encounter (P = .044) post AM-LAI. Total inpatient encounters were also reduced (P = .004), although no differences in encounters for psychiatric reasons were detected. Discussion Use of AM-LAI was associated with a prolonged time to next inpatient encounter and reduced total inpatient encounters, however its use failed to demonstrate reductions in psychiatric encounters.

Abstract
Background Several previous observational studies have reported the risk factors associated with readmission in people with mental illness. While patient-reported experiences and outcomes have become increasingly important in healthcare, only a few studies have examined these parameters in terms of their direct association with readmission in an acute psychiatric setting. This project will investigate multiple factors associated with readmission and community living in acute psychiatric patients in Japan. This study will primarily investigate whether patient-reported experiences at discharge, particularly quality of life (QoL), are associated with future readmission and whether readmission after the index hospitalization is associated with changes in patient-reported outcomes during the study period. Here, we describe the rationale and methods of this study. Methods This multicenter prospective cohort study is being conducted in 21 participating Japanese hospitals, with a target sample of approximately 600 participants admitted to the acute psychiatric ward. The study has four planned assessment points: time of index admission (T1), time of discharge (from the index admission) (T2), 6 months after discharge from the index admission (T3), and 12 months after discharge from the index admission (T4). Participants will complete self-reported measures including a QoL scale, a subjective disability scale, and an empowerment- and self-agency-related scale at each assessment point; additionally, service satisfaction, subjective view of need for services, and subjective relationships with family members will be assessed at T2 and T3. We will assess the participants’ hospitalization during the study period and evaluate several potential individual- and service-level factors associated with readmission and patient-reported experiences and outcomes. Multivariate analyses will be conducted to identify potential associations between readmission and patient-reported experiences and outcomes. Discussion The present study may produce evidence on how patient-reported experiences at discharge influence readmission and on the influence of readmission on the course of patient-reported outcomes from admission to community living after discharge. The study may contribute to improving care for both patients’ subjective views of their own health conditions and their community lives in an acute psychiatric setting.

Abstract
PURPOSE Olanzapine is a commonly prescribed antipsychotic available as oral and long-acting injectable (LAI) formulations. Data are lacking on the use and safety of olanzapine-LAI in older patients. The aim of this study was to investigate the effect of increasing age on olanzapine exposure during oral versus LAI administration in a real-life setting. METHODS This observational study was based on routine therapeutic drug monitoring data collected during 2005-2017. As a measure of exposure, absolute concentrations and concentration/dose ratios of olanzapine were defined as outcome variables. Linear mixed-model analyzes were used to allow for inclusion of multiple samples per patient and adjustment for covariate effects. RESULTS Olanzapine concentrations and doses from 8,288 patients (21,378 measurements) were included. The number of patients on oral treatment was 7,893 (42%, 50 years or older), while 395 were using olanzapine-LAI (27%, 50 years or older). In contrast to oral use, where the dose-adjusted concentration of olanzapine increased significantly for patients 50 years or older (P < 0.001), increasing age had no effect on olanzapine concentration following LAI administration (P = 0.550). The effects of smoking habits and gender were equal in oral and olanzapine-LAI users. CONCLUSION While the dose-adjusted systemic exposure of olanzapine increases by age after oral administration, these novel findings from a large patient population show that systemic exposure of olanzapine-LAI is unaffected by age, probably due to the lacking influence of age-related changes in gastrointestinal absorption and/or presystemic metabolism. From a pharmacokinetic point of view, it is therefore no reason to restrict the use of olanzapine-LAI in older patients requiring long-term treatment.

Comparative Efficacy and Safety of Long-acting Injectable and Oral Second-generation Antipsychotics for the Treatment of Schizophrenia: A Systematic Review and Meta-analysis. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2018; 16:361-375.

Abstract
We aimed to compare the efficacy and safety of long-acting injectable (LAI) and oral second-generation antipsychotics (SGAs) in treating schizophrenia by performing a systematic review and meta-analysis. MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library, as well as five Korean databases, were systemically searched to identify studies published from 2000 to 16 April 2015, which compared the efficacy and safety of LAI and oral SGAs. Using data from randomized controlled trials (RCTs), meta-analyses were conducted. In addition, the GRADE (the Grading of Recommendations, Assessment, Development and Evaluation) approach was applied to explicitly assess the quality of the evidence. A total of 30 studies including 17 RCTs and 13 observational studies were selected. The group treated with LAI SGAs was characterized by significantly lower relapse rates, longer times to relapse and fewer hospital days, but also by a higher occurrence of extrapyramidal syndrome and prolactin-related symptoms than that in the group treated with oral SGAs. Our findings demonstrate that there is moderate to high level of evidence suggesting that in the treatment of schizophrenia, LAI SGAs have higher efficacy and are associated with higher rates of extrapyramidal syndrome and prolactin-related symptoms. Additionally, the use of LAI SGAs should be combined with appropriate measures to reduce dopamine D2 antagonism-related symptoms.

Abstract
OBJECTIVE Examine cost-driving factors of schizophrenia in Germany for patients prior- and post-switch from an oral antipsychotic therapy to aripiprazole-depot and perform a budget impact analysis (BIA) referring to the context of German health care. METHODS A single-armed, retrospective, non-interventional pre-post comparison study with 132 patients to compare the total psychiatric hospitalization rates and the associated costs of both, the treatment with oral antipsychotics and aripiprazole-depot. The BIA was performed to compare both treatment periods with respect to health-related costs. A subsequent univariate sensitivity analysis examined the robustness of the results. RESULTS After switching the treatment to aripiprazole-depot, the total psychiatric hospitalization rates for the 6-month treatment period were significantly (p < 0.001) lower (14%) compared to the hospitalization rates when treated with oral antipsychotics (55.1%). 18.2% of the patients reported to be employed, with 29.2% having work incapacities. The mean number of schizophrenia episodes was 2.58 episodes per patient during the oral-antipsychotic treatment compared to 0.41 episodes per patient during the aripiprazole-depot phase (p < 0.001). The treatment with aripiprazole-depot also significantly reduced the mean number of hospitalizations per patient (0.63 to 0.16, p < 0.001) and the mean number of hospitalized days (27.39 to 5.56, p < 0.001) compared to the oral antipsychotic treatment. Additionally a significant reduction of the mean stay in day-clinics and psychiatric institute ambulances (PIAs) was observed (46.13 days to 7.29 days, p < 0.01). Treatment of a patient suffering from schizophrenia with oral antipsychotics produced costs of 9935.38€ (direct costs: 9498.36 €), while aripiprazole-depot generated costs of 4557.56€ (direct costs: 4449.83 €) per patient for a one-year observation period. This resulted in total costs of 6,517,606,265.43€ for the oral antipsychotic treatment and 2,989,756,603.05€ for aripiprazole-depot treatment from the perspective of the German health care system. The results remained robust during sensitivity analysis, with aripiprazole-depot being the more cost-effective strategy. CONCLUSIONS The results suggest that aripiprazole-depot treatment for schizophrenia patients has major potential in terms of cost savings for the German statutory health insurance.

Abstract
OBJECTIVE To compare treatment patterns and Medicaid spending between schizophrenia patients initiating once-monthly paliperidone palmitate (PP1M) and oral atypical antipsychotics (OAAs) within four comorbid populations: cardiovascular disease (CVD), diabetes, hypertension and obesity. METHODS Five-state Medicaid data identified comorbid adults with schizophrenia initiating PP1M or OAAs (index) from September 2009 balanced with inverse probability of treatment weighting. Chi-squared and t-tests compared index antipsychotic (AP) exposure (no gap >90 days) duration, AP polypharmacy, and index AP adherence (proportion of days covered ≥80%) and persistence (no gap ≥60 days) at 12 months post-index. Linear models with a non-parametric bootstrap procedure compared costs. RESULTS PP1M patients consistently had longer index AP exposure (e.g. CVD: 244 vs. 189 days; p < .001) and less AP polypharmacy (e.g. CVD: 21.1% vs. 28.1%; p < .001) versus OAA patients. Relative to OAA patients, adherence was more likely in PP1M patients with CVD or obesity (e.g. CVD: 28.6% vs. 22.1%; p < .001) and less likely for patients with diabetes (22.0% vs. 24.4%; p = .031). Persistence was consistently more likely for PP1M versus OAA patients (e.g. CVD: 49.9% vs. 27.4%; p < .001). Total costs were not significantly different between PP1M and OAA patients for any comorbidity. PP1M patients with diabetes, hypertension or obesity had higher pharmacy and lower medical costs (all p < .05). CONCLUSIONS Treatment with PP1M versus OAAs may reduce AP polypharmacy and increase AP persistence in comorbid patients with schizophrenia, without increasing total healthcare costs. Comorbidities are a highly prevalent driver of excess mortality in this vulnerable population; thus, future studies should specifically address the real-world effectiveness of therapies, including long acting injectable therapies (LAIs), for these patients.

Abstract
Introduction: Despite the theory that long-acting injectable (LAI) antipsychotics should be more likely to improve adherence, reduce gaps in therapy, and prevent relapse compared with oral antipsychotics, there is little published evidence on this issue, specifically in patients with early psychosis. Methods: Patients with a new diagnosis for a psychotic disorder between July 1, 2013, and August 31, 2014, were retrospectively evaluated during a 12-month duration. The primary outcomes were adherence and persistence. Adherence was determined by proportion of days with medication, and persistence was defined as zero gaps in medication therapy. The secondary outcome was the number of times a psychiatric acute care service was used. Patients were divided into 3 groups based on their antipsychotic prescription history: oral only, LAI only, or both formulations at separate times throughout the study period. Results: Forty-seven patients met inclusion criteria. The average proportions of days with medication were 32%, 76%, and 75% for the oral, LAI, and both formulations groups, respectively (P < .001). For medication persistence, there were 32 patients (91%), 3 patients (75%), and 5 patients (63%) with at least 1 gap in therapy for the oral, LAI, and both formulations groups, respectively (P = .098). For acute care services, there was a median number of zero acute care visits for each of the 3 groups (P = .179). A post hoc subgroup analysis found medication adherence to be statistically different between the oral and LAI groups. Discussion: Long-acting injectable antipsychotics were associated with better adherence compared with oral antipsychotics in patients with early psychosis.

Abstract
OBJECTIVE To assess trends in and risk factors for readmission to hospital across the age continuum. DESIGN Retrospective analysis. SETTING AND PARTICIPANTS 31 729 762 index hospital admissions for all conditions in 2013 from the US Agency for Healthcare Research and Quality Nationwide Readmissions Database. MAIN OUTCOME MEASURE 30 day, all cause, unplanned hospital readmissions. Odds of readmission were compared by patients' age in one year epochs with logistic regression, accounting for sex, payer, length of stay, discharge disposition, number of chronic conditions, reason for and severity of admission, and data clustering by hospital. The middle (45 years) of the age range (0-90+ years) was selected as the age reference group. RESULTS The 30 day unplanned readmission rate following all US index admissions was 11.6% (n=3 678 018). Referenced by patients aged 45 years, the adjusted odds ratio for readmission increased between ages 16 and 20 years (from 0.70 (95% confidence interval 0.68 to 0.71) to 1.04 (1.02 to 1.06)), remained elevated between ages 21 and 44 years (range 1.02 (1.00 to 1.03) to 1.12 (1.10 to 1.14)), steadily decreased between ages 46 and 64 years (range 1.02 (1.00 to 1.04) to 0.91 (0.90 to 0.93)), and decreased abruptly at age 65 years (0.78 (0.77 to 0.79)), after which the odds remained relatively constant with advancing age. Across all ages, multiple chronic conditions were associated with the highest adjusted odds of readmission (for example, 3.67 (3.64 to 3.69) for six or more versus no chronic conditions). Among children, young adults, and middle aged adults, mental health was one of the most common reasons for index admissions that had high adjusted readmission rates (≥75th centile). CONCLUSIONS The likelihood of readmission was elevated for children transitioning to adulthood, children and younger adults with mental health disorders, and patients of all ages with multiple chronic conditions. Further attention to the measurement and causes of readmission and opportunities for its reduction in these groups is warranted.

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 objective of this study was to compare persistence, costs, and healthcare resource utilization in patients with schizophrenia and cardiometabolic comorbidities treated with once-monthly paliperidone palmitate or an oral atypical antipsychotic. Methods Medicaid data from six states (07/2009–03/2015) were used to identify adults with schizophrenia and cardiometabolic comorbidities initiated on once-monthly paliperidone palmitate or an oral atypical antipsychotic (index date) on 01/2010 or after. Persistence to index medication at 12 months (no gap ≥ 90 days) was compared between patients taking once-monthly paliperidone palmitate and an oral atypical antipsychotic using Chi-squared tests. The 12-month post-index healthcare costs and healthcare resource utilization were compared using multivariate ordinary least squares and Poisson regression, respectively. Results Selected patients taking once-monthly paliperidone palmitate (n = 371) were younger (mean age: 45.0 vs. 47.5 years, standardized difference = 24%) than patients taking oral atypical antipsychotics (n = 8296). Persistence at 12 months was higher in patients taking once-monthly paliperidone palmitate (40 vs. 33%, p = 0.006). Adjusted all-cause medical costs were lower in patients taking once-monthly paliperidone palmitate vs. patients taking oral atypical antipsychotics (mean monthly cost differences = US $ − 369, p = 0.004) while all-cause pharmacy costs were higher (mean monthly cost differences = US $279, p < 0.001), resulting in no significant difference in total costs (mean monthly cost differences = US $ − 90, p = 0.357). No significant difference was observed in cardiometabolic comorbidity-related pharmacy or medical costs. Compared with patients taking oral atypical antipsychotics, patients taking once-monthly paliperidone palmitate had more schizophrenia-related outpatient visits (incidence rate ratio = 1.44, p < 0.001) but fewer cardiometabolic comorbidity-related inpatient admissions (incidence rate ratio = 0.73, p < 0.001) with shorter lengths of stay (incidence rate ratio = 0.72, p = 0.020), and fewer cardiometabolic comorbidity-related long-term care admissions (incidence rate ratio = 0.56, p = 0.016). Conclusions Medicaid beneficiaries with schizophrenia and cardiometabolic comorbidities who were initiated on once-monthly paliperidone palmitate had similar 12-month total healthcare costs compared with oral atypical antipsychotics. Cardiometabolic comorbidity-related utilization of inpatient and long-term care services was lower in patients taking once-monthly paliperidone palmitate.

Abstract
We investigated the relative efficacy and tolerability of aripiprazole once monthly (AOM) versus paliperidone palmitate (PP) for treating schizophrenia. Extensive databases searches on short-term, placebo-controlled, randomized studies of AOM and PP were performed. Indirect treatment comparisons were performed between the two long-acting injectable antipsychotics (LAIAs). The primary efficacy endpoint was the mean change in the Positive and Negative Syndrome Scale total score from baseline between each LAIA and placebo. The effect sizes were mean differences and odds ratio (ORs) with 95% confidence intervals (CIs) for the primary efficacy endpoint and safety/tolerability between two LAIAs, respectively. Mean difference in the primary efficacy endpoint was significantly different, favouring AOM over PP (OR: -6.4; 95% CI: -11.402 to -1.358); sensitivity analyses and noninferiority test (AOM vs. PP) confirmed the primary results. The overall early dropout rate was not significantly different between AOM and PP (OR: 1.223; 95% CI: 0.737-2.03). However, there was a significant difference in the early dropout rate in terms of lack of efficacy favouring AOM over PP (OR: 0.394; 95% CI: 0.185-0.841). Within the context of the inherent limitations of the current analysis, our results may suggest that there may be relative advantages for AOM over PP in the short-term treatment of schizophrenia.

Abstract
Schizophrenia is a mostly chronic mental disorder, and symptomatic relapse is frequently observed. It is often associated with social and/or occupational decline that can be difficult to reverse. Most patients with the illness need long-term pharmacological treatment, and antipsychotic drugs represent the mainstay of clinical care. Long-acting injectable antipsychotics (LAIs) are an important alternative to oral medication, particularly advantageous in the context of compliance management. Several new-generation antipsychotics (NGAs), including risperidone, olanzapine, paliperidone, and aripiprazole, have become available as long-acting formulations, and new evidence has been accumulating. To date, all of the NGA LAIs have demonstrated a statistically and clinically significant decrease of relapse rates over placebo. The results of clinical trials comparing NGA LAIs with oral antipsychotics (OAPs) are not consistent, as being influenced considerably by study design. Superiority of LAIs to OAPs in efficacy is most evident in mirror image and cohort studies. New-generation LAIs are comparable to their oral mother compounds regarding safety and tolerability if one disregards potential injection site complications. There is little evidence of efficacy differences between the available LAIs, but they have different characteristics in terms of pharmacodynamic and pharmacokinetic profiles, injection interval, cost, requirements for oral supplementation, as well as adverse events. Considering these differences is useful for selecting LAIs for the treatment of individual patients. There is increasing evidence suggesting the use of LAIs in special patient groups, such as first-episode or forensic schizophrenia patients. This article reviews data on the use of NGA LAIs in schizophrenia and discusses current issues from clinical and methodological perspectives.

Abstract
BACKGROUND Poor antipsychotic (AP) adherence is a key issue in patients with schizophrenia. First-generation antipsychotic (FGA) and second-generation antipsychotic (SGA) long-acting injectable therapies (LAI) may improve adherence compared to oral antipsychotics (OAP). The objective of the study was to compare treatment adherence and persistence in Medicaid patients with schizophrenia initiated on first-generation long-acting injectable therapies (FGA-LAI) or second-generation long-acting injectable therapies (SGA-LAI) versus OAP. METHODS Adults with schizophrenia initiated on FGA-LAI, SGA-LAI, or OAP on or after January 2010 were identified using a six-state Medicaid database (January 2009-March 2015). Outcomes were assessed during the 12 months following treatment initiation. Index medication adherence was assessed using the proportion of days covered ≥80%, while persistence was assessed as no gap of ≥30, ≥60, or ≥90 days between days of supply. Outcomes were compared between FGA/SGA-LAI and OAP cohorts using chi-squared tests and adjusted odds ratios (OR). RESULTS During follow-up, AP polypharmacy was more common in FGA-LAI patients (N=1,089; 36%; P=0.029) and less common in SGA-LAI patients (N=2,209; 27%; P<0.001) versus OAP patients (N=20,478; 33%). After adjustment, SGA-LAI patients had 24% higher odds of adherence at 12 months (OR: 1.24; P<0.001), in contrast to FGA-LAI patients who had 48% lower odds of adherence (OR: 0.52; P<0.001) relative to OAP patients. SGA-LAI patients were more likely to be persistent (no gap ≥60 days) at 12 months than OAP patients (37% vs 30%; P<0.001), but not FGA-LAI patients (31% vs 30%; P=0.776). In comparison to OAP patients, SGA-LAI patients had 46% higher adjusted odds of persistence (no gap ≥60 days; OR: 1.46; P<0.001), while FGA-LAI patients were not significantly different (OR: 0.95; P=0.501). CONCLUSION Medicaid patients initiated on SGA-LAI demonstrated better treatment adherence and persistence compared to OAP patients, while those initiated on FGA-LAI did not show significant improvement in adherence or persistence and had more AP polypharmacy relative to OAP patients. These findings suggest the potential value of SGA-LAI in the treatment of schizophrenia.

Abstract
Schizophrenia presents unique difficulties in clinical trial design associated with the condition's variable presentation and clinical course, and multiple features influencing affect, cognition, volition and perception. Randomized controlled trials (RCTs) are explanatory studies using a carefully selected patient population, predefined assessment intervals and, generally, symptom-focused endpoints. Naturalistic studies are pragmatic, with no active intervention, and outcomes that are generally those used in clinical practice (e.g. hospitalization, relapse rate). Both naturalistic studies and RCTs have pros and cons, making it difficult for physicians in clinical practice to apply research findings to their own treatment decisions. The choice of clinical trial design can have a significant impact on the comparative effectiveness or efficacy of drugs. This is particularly true for studies comparing long-acting injectable (LAI) antipsychotics with oral antipsychotics in schizophrenia, in which RCTs generally show no benefit for LAIs over oral drugs, whereas observational studies do. The more pragmatic the study design, the more likely it is to show a benefit for LAIs versus oral therapy. This article reviews the pros and cons of different study types, using published examples. Criteria are outlined to help physicians design appropriate prospective studies in schizophrenia including the relevant pragmatic and/or explanatory features, as required.

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
Introduction Long-acting injectable antipsychotics (LAIs) serve as a means to ensure medication adherence with the intention of improving outcomes for psychiatric patients. Evidence remains inconclusive regarding the impact of LAIs on relapses and psychiatric hospitalizations rates. Methods The primary objective of this retrospective pre/post study was to determine whether initiating an LAI in a veteran population with schizophrenia, schizoaffective disorder, or bipolar disorder is associated with a decrease in the 1-year rate of psychiatric hospitalizations and emergency room (ER) visits. Results For the combined primary endpoint, the 1-year rate of psychiatric hospitalizations and ER visits for patients with schizophrenia, schizoaffective disorder, or bipolar disorder was not significantly reduced after initiation of LAIs (n = 50, median [interquartile range]: 1.5 [1, 3] to 1 [0, 3], P = .055). However, the secondary endpoint of the 1-year rate of psychiatric hospitalizations was reduced (1 [0, 3] to 0 [0, 2], P = .026). Additionally, for those who received injections on a regular basis, the 1-year rate of hospitalizations and ER visits was significantly reduced (2 [1, 3] to 0 [0, 1.5], P = .009). Discussion This retrospective study suggests that the initiation of LAIs is associated with a reduced rate of psychiatric hospitalizations as well as a reduced rate of psychiatric hospitalizations and ER visits for those patients who receive injections on a regular basis.

Abstract
BACKGROUND Non-adherence to antipsychotic therapy among patients with schizophrenia is a key driver of relapse, which can lead to costly inpatient stays. Long-acting injectables (LAIs) may improve adherence, thus reducing hospitalizations, but inpatient cost reductions need to be balanced against higher drug acquisition costs of LAIs. Real-world evidence is needed to help quantify the economic value of oral atypical antipsychotics compared with LAIs. OBJECTIVE The objective of this study was to compare healthcare costs and resource utilization between once-monthly paliperidone palmitate (PP) and oral antipsychotic therapy (OAT) in a population of Medicaid beneficiaries with schizophrenia. METHODS A retrospective, observational study was performed using Truven Health MarketScan Medicaid claims data from 2009 to 2012. Marginal structural modeling, a form of weighted repeated measures analysis to control for differences between cohorts and time-varying confounding, was used to estimate monthly costs of care in 2012 US dollars and resource utilization over a 12-month period for patients in each cohort. RESULTS While per-month mental-health prescription costs were US$1019 higher in the PP cohort, approximately 55 % of this premium was offset by lower inpatient and outpatient care costs, producing a mean monthly total cost differential of US$434 (95 % CI 298-569, p < 0.0001) for all-cause costs and US$463 (95 % CI 374-552, p < 0.0001) for mental-health-related costs. Use of PP also resulted in a 0.44 and 0.47 reduction in the odds of all-cause and mental-health-related hospitalizations and a 0.09 reduction in the odds of all-cause emergency department visits (p < 0.0001, p < 0.0001, and p = 0.0134, respectively) over the 12-month follow-up period. CONCLUSIONS Treatment with long-acting injectable antipsychotics, such as PP, may reduce inpatient and outpatient healthcare services utilization and associated costs. These findings also suggest that patients with schizophrenia taking once-monthly PP may stand a lower risk of hospitalization than patients on OAT.

Abstract
Relapse in schizophrenia has been associated with poor adherence to oral medication. A possible method to optimize medication adherence could be to switch patients from oral to depot medication. In this respect, aripiprazole long acting injectable (ALAI) significantly delayed time to impending relapse when compared with placebo (p < 0.0001), while ALAI was generally well tolerated during both short-term and long-term studies. A literature search, using PubMed was conducted to identify relevant publications. Available evidence suggests that ALAI may be a viable treatment option for patients with schizophrenia, but before it can be concluded whether or not all schizophrenia patients could benefit from a switch to depot formulations, several questions remain to be answered. Thus, there is a great need for randomized controlled trials comparing depot medications with their oral equivalents.
