Abstract
OBJECTIVE To describe patterns of antipsychotic switching among patients hospitalized for schizophrenia and to correlate antipsychotic switching with hospital readmission risk. METHODS We identified 3295 patients with index hospitalizations for schizophrenia or schizoaffective disorder from New York State Medicaid claims 2017-2018 who had filled at least one prescription for an antipsychotic in both the 44 days (one month +14 day grace period) prior to and after their admission. We identified patients who had kept or switched any of their antipsychotic medication between the pre- and post-periods surrounding their index hospitalization. We compared the kept and switched any groups, adjusting for patient characteristics. RESULTS Of patients who had filled antipsychotic prescriptions in both the 44 days prior to and after their hospitalization, 1599 (48.6 %) had switched at least one antipsychotic and 1215 (36.8 %) had switched their primary antipsychotic. Switching any antipsychotic was associated with increased hazards of readmission, HR = 1.21, 95%CI 1.09-1.35, which was slightly concentrated during the first 90 days after hospital discharge. CONCLUSIONS Switching antipsychotic medications during hospitalization occurs commonly and is associated with higher rehospitalization risk following hospital discharge.

Unraveling ethnic disparities in antipsychotic prescribing among patients with psychosis: A retrospective cohort study based on electronic clinical records. Schizophr Res 2023; 260:168-179. [PMID: 37669576 PMCID: PMC10881407 DOI: 10.1016/j.schres.2023.08.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 07/11/2023] [Accepted: 08/27/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Previous studies have shown mixed evidence on ethnic disparities in antipsychotic prescribing among patients with psychosis in the UK, partly due to small sample sizes. This study aimed to examine the current state of antipsychotic prescription with respect to patient ethnicity among the entire population known to a large UK mental health trust with non-affective psychosis, adjusting for multiple potential risk factors. METHODS This retrospective cohort study included all patients (N = 19,291) who were aged 18 years or over at their first diagnoses of non-affective psychosis (identified with the ICD-10 codes of F20-F29) recorded in electronic health records (EHRs) at the South London and Maudsley NHS Trust until March 2021. The most recently recorded antipsychotic treatments and patient attributes were extracted from EHRs, including both structured fields and free-text fields processed using natural language processing applications. Multivariable logistic regression models were used to calculate the odds ratios (OR) for antipsychotic prescription according to patient ethnicity, adjusted for multiple potential contributing factors, including demographic (age and gender), clinical (diagnoses, duration of illness, service use and history of cannabis use), socioeconomic factors (level of deprivation and own-group ethnic density in the area of residence) and temporal changes in clinical guidelines (date of prescription). RESULTS The cohort consisted of 43.10 % White, 8.31 % Asian, 40.80 % Black, 2.64 % Mixed, and 5.14 % of patients from Other ethnicity. Among them, 92.62 % had recorded antipsychotic receipt, where 24.05 % for depot antipsychotics and 81.72 % for second-generation antipsychotic (SGA) medications. Most ethnic minority groups were not significantly different from White patients in receiving any antipsychotic. Among those receiving antipsychotic prescribing, Black patients were more likely to be prescribed depot (adjusted OR 1.29, 95 % confidence interval (CI) 1.14-1.47), but less likely to receive SGA (adjusted OR 0.85, 95 % CI 0.74-0.97), olanzapine (OR 0.82, 95 % CI 0.73-0.92) and clozapine (adjusted OR 0.71, 95 % CI 0.6-0.85) than White patients. All the ethnic minority groups were less likely to be prescribed olanzapine than the White group. CONCLUSIONS Black patients with psychosis had a distinct pattern in antipsychotic prescription, with less use of SGA, including olanzapine and clozapine, but more use of depot antipsychotics, even when adjusting for the effects of multiple demographic, clinical and socioeconomic factors. Further research is required to understand the sources of these ethnic disparities and eliminate care inequalities.

Antipsychotic utilization, healthcare resource use and costs, and quality of care among fee-for-service Medicare beneficiaries with schizophrenia in the United States. J Med Econ 2023; 26:525-536. [PMID: 36961119 DOI: 10.1080/13696998.2023.2189859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 03/07/2023] [Accepted: 03/08/2023] [Indexed: 03/25/2023]
Abstract
BACKGROUND No research to date has examined antipsychotic (AP) use, healthcare resource use (HRU), costs, and quality of care among those with schizophrenia in the Medicare program despite it serving as the primary payer for half of individuals with schizophrenia in the US. OBJECTIVES To provide national estimates and assess regional variation in AP treatment utilization, HRU, costs, and quality measures among Medicare beneficiaries with schizophrenia. METHODS Cross-sectional descriptive analysis of 100% Medicare claims data from 2019. The sample included all adult Medicare beneficiaries with continuous fee-for-service coverage and ≥1 inpatient and/or ≥2 outpatient claims with a diagnosis for schizophrenia in 2019. Summary statistics on AP use; HRU and cost; and quality measures were reported at the national, state, and county levels. Regional variation was measured using the coefficient of variation (CoV). RESULTS We identified 314,888 beneficiaries with schizophrenia. About 91% used any AP; 20% used any long-acting injectable antipsychotic (LAI); and 14% used atypical LAIs. About 28% of beneficiaries had ≥1 hospitalization and 47% had ≥1 emergency room (ER) visits, the vast majority of which were related to mental health (MH). Total annual all-cause, MH, and schizophrenia-related costs were $23,662, $15,000 and $12,109, respectively. Among those with hospitalizations, 18.4% and 27.3% had readmission within 7 and 30 days and 56% and 67% had a physician visit and AP fill within 30 days post-discharge, respectively. Overall, 81% of beneficiaries were deemed adherent to their AP medications. Larger interstate variations were observed in LAI use than AP use (CoV: 0.21 vs 0.02). County-level variations were larger than state-level variations for all measures. CONCLUSIONS In this first study examining a national sample of Medicare beneficiaries with schizophrenia, we found low utilization rates of LAIs and high levels of hospital admissions/readmissions and ER visits. State and county-level variations were also found in these measures.

Abstract
OBJECTIVE Variation in prescription of psychotropic medications to patients with schizophrenia spectrum disorders may underlie health inequities. Using a national U.S. Medicaid sample, the authors examined prescription patterns of psychotropic medications commonly used for managing schizophrenia. METHODS Data from the 2011-2012 Medicaid Analytic eXtract were examined for demographic predictors of and variation across states in psychotropic medication prescription among adult patients diagnosed as having schizophrenia spectrum disorders (N=357,914). Percentages of patients in each state who filled prescriptions of at least 15 days of any antipsychotic, clozapine, antidepressant, benzodiazepine, mood stabilizer, or long-acting injectable (LAI) antipsychotic medication were determined after adjustment for demographic and clinical covariates. Multivariate regressions of clinical and demographic factors predicting prescription patterns were conducted. RESULTS Prescribing patterns for all types of psychotropic medications varied across states. Clozapine and LAI prescriptions showed the most dramatic differences across states and among patients with different demographic characteristics. Across states, adjusted proportions of prescriptions ranged from 4% to 22% for LAIs and from 1% to 11% for clozapine. Non-Hispanic Blacks and people of other race-ethnicities were more likely than non-Hispanic Whites to fill prescriptions for LAIs, and non-Hispanic Whites were more likely than individuals from other racial-ethnic groups to fill prescriptions for clozapine and all other medications. CONCLUSIONS Considerable variation in prescribing patterns of LAIs and clozapine by race-ethnicity and across states suggests uneven quality of care for individuals with schizophrenia spectrum disorders in the United States. A better understanding of what causes this variation could inform policy makers to improve treatment for this vulnerable population.

Abstract
Schizophrenia is ranked among the top 25 leading causes of disability worldwide in 2013 which resulting in social and economic burden. By observing patients with schizophrenia one year before and after switching from oral antipsychotics (OAPs) to once-monthly paliperidone palmitate (PP1M), we can better understand the change of total costs in schizophrenic patients, including direct costs and indirect costs, after switching treatment patterns.A total of 100 schizophrenic (ICD-10) patients from Shandong Mental Health Center were collected from December 2016 to June 2019. Treatment modalities, health care resource utilization and costs were compared before and after switching directly from oral antipsychotics to PP1M.Of the 82 patients included in the main analyses, treatment with PP1M resulted in an increase in direct costs of 31.92% (P < 0.01), an increase in medicine costs of approximately 142% (P < 0.01), and a reduction in hospital costs of 68.15% (P > 0.05). There was no significant increase in total costs (P = 0.25), while 31.92% increase in direct costs (P < 0.01), and 35.62% decrease in indirect costs (P < 0.01) after conversion to PP1M. Compared with before administration of PP1M, patients with ≥ 1 inpatient stay in 1 year Pre-PP1M treatment with OAPs (n = 32) had a 20.16% decrease in direct costs (P < 0.01), a 144% increase in medicine costs (P < 0.01), and a significant 72.02% decrease in hospital costs (P < 0.01). The observed reduction in the number of hospitalizations (t = 2.56, P ≤ 0.01) and inpatient stays (t = 1.73, P < 0.05) and after transition to PP1M resulted in a reduction in hospitalization costs (P < 0.01).Switching from OAPs to PP1M decreased the household workforce burden without increasing clinical healthcare costs. Direct costs were significantly reduced in patients with ≥ 1 inpatient stay in 1 year pre-PP1M treatment with OAPs after the switch, which decreased by improving adherence to therapy and reducing the number and length of hospital stays, suggesting that those patients may benefit after switching to PP1M.

Abstract
OBJECTIVE The primary aim was to examine the use of long-acting injectable (LAI) antipsychotic (depot) medication in a cohort of older patients in a community psychogeriatric service. METHOD From 2014 to 2018, all patients who were on LAIs each year were analysed for various characteristics including their profile, type of LAI used, dose and relapse rates related to switching, ceasing and community treatment order (CTO) use. RESULTS A total of 880 patients were managed by the service with 142 recorded cases of LAI use in total over the 5 years (16.1%). Second-generation antipsychotics (SGAs) outnumbered first-generation antipsychotics (FGAs) by 2:1, with a trend of increasing use of SGA LAIs. The most commonly used LAI was Paliperidone monthly injection (PP1M) (50.7%). Lower than usual adult chlorpromazine equivalent daily doses of LAIs were used. The relapse rate while on a LAI was 13.4%. Moreover, 54.9% of the patients on LAIs were on a CTO. Relapse rates were lower on LAIs in combination with a CTO (7.7%). CONCLUSIONS LAIs, especially the SGAs, are increasingly used in our service. In combination with a CTO, LAIs are an effective treatment in reducing relapse rates in the elderly.

Abstract
IMPORTANCE Little is known about changes in care for individuals with severe mental illness during the COVID-19 pandemic. OBJECTIVE To examine changes in mental health care during the pandemic and the use of telemedicine in outpatient care among Medicare beneficiaries with severe mental illness. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study included Medicare beneficiaries (age ≥18 years) diagnosed with schizophrenia and schizophrenia-related disorders or bipolar I disorder. Care patterns during January to September 2020 for a cohort defined in 2019 were compared with those during January to September 2019 for a cohort defined in 2018. EXPOSURES Start of COVID-19 pandemic in the United States, defined as week 12 of 2020. MAIN OUTCOMES AND MEASURES Use of mental health-related outpatient visits, emergency department visits, inpatient care, and oral prescription fills for antipsychotics and mood stabilizers during 4-week intervals. Multivariable logistic regression analyses examined whether the pandemic was associated with differential changes in outpatient care across patient characteristics. RESULTS The 2019 cohort of 686 214 individuals included 389 245 (53.8%) women, 114 073 (15.8%) Black and 526 301 (72.8%) White individuals, and 477 353 individuals (66.0%) younger than 65 years; the 2020 cohort of 723 045 individuals included 367 140 (53.5%) women, 106 699 (15.6%) Black and 497 885 (72.6%) White individuals, and 442 645 individuals (64.5%) younger than 65 years. Compared with 2019, there were large decreases during the pandemic's first month (calendar weeks 12-15) in individuals with outpatient visits (265 169 [36.7%] vs 200 590 [29.2%]; 20.3% decrease), with antipsychotic and mood stabilizer medication prescription fills (216 468 [29.9%] vs 163 796 [23.9%]; 20.3% decrease), with emergency department visits (12 383 [1.7%] vs 8503 [1.2%]; 27.7% decrease), and with hospital admissions (11 564 [1.6%] vs 7912 [1.2%]; 27.9% decrease). By weeks 32 to 35 of 2020, utilization rebounded but remained lower than in 2019, ranging from a relative decrease of 2.5% (outpatient visits) to 12.9% (admissions). During the full pandemic period (weeks 12-39) in 2020, 1 556 403 of 2 743 553 outpatient visits (56.7%) were provided via telemedicine. In multivariable analyses, outpatient visit use during weeks 12 to 25 of 2020 was lower among those with disability (odds ratio, 0.95; 95% CI, 0.93-0.96), and during weeks 26 to 39 of 2020, it was lower among Black vs non-Hispanic White individuals (OR, 0.97; 95% CI, 0.95-0.99) and those with dual Medicaid eligibility (OR, 0.96; 95% CI, 0.95-0.98). CONCLUSIONS AND RELEVANCE In this cohort study, despite greater use of telemedicine, individuals with severe mental illness experienced large disruptions in care early in the pandemic. These narrowed but persisted through September 2020. Disruptions were greater for several disadvantaged populations.

Abstract
Background: Severe mental disorders (SMD) impose a heavy burden on individuals, society, and the country. Under the background of deinstitutionalization, more and more patients return to the community, and the community psychiatric management physicians (CPMP) play an essential role in this process. Long-acting injection (LAI) is an important way to improve compliance and reduce re-hospitalization. Some districts in Beijing have implemented the policy of free LAI. This article aims to find out the willingness of CPMP to preferentially recommend LAI and provide suggestions for follow-up promotion. Methods: All CPMP in 16 districts of Beijing were surveyed. A self-made electronic questionnaire was used to investigate the willingness to recommend LAI in priority. Descriptive statistics, Chi-square test, and logistic regression were used to analyze the data. Results: The willingness of CPMP to preferentially recommend LAI is up to 80%. Participants aged 40–49, female, with higher self-evaluation of psychiatric management knowledge, managing patients who have used LAI in the past, and working in communities with the free LAI policy have higher willingness to recommend LAI in priority. Conclusion: CPMP in Beijing have a positive attitude toward LAI, and most of them have the willingness to recommend LAI to the patients in priority. The recommendation willingness is the basis of prescription decision-making. Therefore, the coverage of free LAI policy should be further expanded in the future to improve the recommendation willingness and thus improve the injection rate of LAI.

Abstract
OBJECTIVE The Multilevel Facilitation of Long-Acting Antipsychotic Medication Program (MAP) is a novel intervention to increase the appropriate use of long-acting injectable (LAI) antipsychotics in community mental health clinics. The authors investigated the feasibility of MAP, facilitators and barriers to use, and preliminary impact on LAI medication use. METHODS Two clinics in Texas and two in Ohio serving 750 and 617 individuals with schizophrenia receiving oral antipsychotics, respectively, were asked to change clinical procedures for 1 year by using either the not receiving optimum benefit (NOB) checklist or the checklist plus MAP. Providers used the NOB checklist to identify individuals who could benefit from switching to LAI antipsychotics. MAP clinics used the NOB checklist plus nonbranded academic detailing for providers and a shared-decision-making video and tool for consumers. Use of MAP components was tracked, and barriers and facilitators were collected quarterly. Antipsychotic prescription counts were provided by participating clinics. RESULTS Barriers to use of MAP included loss of local champions and administrators, difficulty with provider buy-in, limited availability of peer specialists, and a lack of infrastructural support to integrate MAP into clinic flow. Higher scores on the NOB checklist were associated with more provider LAI medication offers and greater patient acceptance of LAI antipsychotics. LAI medication use increased in clinics over time, but it is unclear whether this increase was due to MAP. CONCLUSIONS Changing MAP components to fit local procedures and to circumvent unique barriers could aid implementation. Further research should investigate the potential impact of MAP components on LAI medication use.

Fiore G, Bertani DE, Marchi M, Cardoso G, Galeazzi GM. Patient subjective experience of treatment with long-acting injectable antipsychotics: a systematic review of qualitative studies. JORNAL BRASILEIRO DE PSIQUIATRIA 2021.

Abstract
ABSTRACT Objective: To gain a better understanding of how long-acting injectable antipsychotic (LAI) therapy is perceived by patients. Methods: A search for qualitative studies has been carried out on PubMed, Google Scholar, PsycINFO and PsycArticles, yielding 11 studies suitable for a review of qualitative studies. The reporting approach chosen was meta-ethnography, following the ENTREQ statement recommendations. Key concepts common to the different studies were extrapolated and then analysed in a systematic and comparative way. Results: Some recurrent issues were associated with LAIs, such as fear of coercion, fear of needles and lack of knowledge about depot therapy. These topics are linked to each other and the patients most concerned about the disadvantages of LAIs are those who are less informed about them, or who have experienced coercion and trauma during hospitalisation. On the other hand, patients who had already received LAIs, and those who had a good therapeutic relationship with their healthcare providers expressed satisfaction with this form of treatment and its continuation. Conclusion: Long-acting injectable antipsychotics are a tool in the management of mental disorders, and a viable alternative to oral medication. Patients show curiosity towards this method of administration, but lack of knowledge is a common finding. Shared decision making about the use of LAIs antipsychotics requires that patients receive accurate information and support for their decision regarding medication.

Abstract
INTRODUCTION Patterns of clinical use of long-acting injectable (LAI) antipsychotic drugs in many countries, especially in Asia, for treatment of patients diagnosed with chronic psychotic disorders including schizophrenia are not well established. METHODS Within an extensive research consortium, we evaluated prescription rates for first- (FGA) and second-generation antipsychotic (SGA) LAI drugs and their clinical correlates among 3557 subjects diagnosed with schizophrenia across 15 Asian countries and region. RESULTS Overall, an average of 17.9% (638/3557; range: 0.0%-44.9%) of treated subjects were prescribed LAI antipsychotics. Those given LAI vs orally administered agents were significantly older, had multiple hospitalizations, received multiple antipsychotics more often, at 32.4% higher doses, were more likely to manifest disorganized behavior or aggression, had somewhat superior psychosocial functioning and less negative symptoms, but were more likely to be hospitalized, with higher BMI, and more tremor. Being prescribed an FGA vs SGA LAI agent was associated with male sex, aggression, disorganization, hospitalization, multiple antipsychotics, higher doses, with similar risks of adverse neurological or metabolic effects. Rates of use of LAI antipsychotic drugs to treat patients diagnosed with schizophrenia varied by more than 40-fold among Asian countries and given to an average of 17.9% of treated schizophrenia patients. We identified the differences in the clinical profiles and treatment characteristics of patients who were receiving FGA-LAI and SGA-LAI medications. DISCUSSION These findings behoove clinicians to be mindful when evaluating patients' need to be on LAI antipsychotics amidst multifaceted considerations, especially downstream adverse events such as metabolic and extrapyramidal side effects.

The effectiveness of long-acting injectable antipsychotics versus oral antipsychotics in the maintenance treatment of outpatients with chronic schizophrenia. Hum Psychopharmacol 2020; 35:e2729. [PMID: 32182388 DOI: 10.1002/hup.2729] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 02/11/2020] [Accepted: 02/16/2020] [Indexed: 01/28/2023]
Abstract
OBJECTIVE To compare the psychiatric service utilization between patients who only received long-acting injectable antipsychotics (LAIAs) and those who only received oral antipsychotics (OAPs) in the maintenance treatment of chronic schizophrenia. METHODS We constructed a cohort of chronic schizophrenia patients who underwent maintenance treatment from the Taiwan National Health Insurance Research Database in 2011 and followed these patients for 12 months. We included patients who had been diagnosed with schizophrenia for at least 3 years, were not hospitalized in 2011, and had received 1 year of maintenance treatment. Inverse probability of treatment weighting logistic, linear, and negative binomial regression models were used to estimate associated psychiatric services utilization and adjust for covariate imbalances between the LAIAs and OAPs groups. RESULTS Among 40,194 patients, 948 (2.36%) received only LAIAs and 39,246 (97.64%) received only OAPs. Compared with those who received only OAPs, the sole LAIAs users were associated with a lower percentage of psychiatric hospitalization (8.4% and 5.8%, respectively; odds ratio: 0.63, p < .01), shorter lengths of hospitalization days (82.8 and 65.9, respectively; coefficient [b]: -16.87, p = .03), and fewer emergency room visits (2.3 and 1.8, respectively; b: -0.24, p < .01) per patient. CONCLUSIONS Chronic schizophrenia patients who received only LAIs had a lower risk of disease relapse and a reduction in psychiatric service utilization than those receiving only OAPs.

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
OBJECTIVE The authors designed this project to identify barriers to using long-acting formulations of antipsychotics. METHODS The authors used a focused ethnographic approach. Patients, psychiatrists, nurses, therapists and administrators were interviewed about barriers to use of long-acting injectable (LAI) antipsychotics at six facilities in New York State, as were representatives from insurance firms, a pharmaceutical company, and a national professional organization. Interviews were conducted and analyzed by a central team not affiliated with the institutions. RESULTS Interviews were obtained with 23 patients, 16 psychiatrists, three nurses, 23 therapists, 14 administrators, four insurers, one representative from a pharmaceutical industry, and one representative from a national organization. Major barriers identified from the interviews included restricting discussions about LAI medication to only patients with nonadherence or repeated hospitalizations; inadequate education efforts with patients about LAI antipsychotics; inadequate support for patients making medication decisions; lack of communication within the treatment team about issues relevant to use of LAI formulations by patients; therapists' limited knowledge about LAI antipsychotics, which restricted their role in supporting patients making treatment decisions; psychiatrist concerns about the pharmacologic properties of LAI formulations; lack of clinic infrastructure to support LAI prescriptions; and payer concerns about whether the immediate costs of LAI administration would translate into later potential cost benefits. CONCLUSIONS Effective shared decision making about use of LAI antipsychotics requires that patients receive accurate information and support for their decision making. The training needs and administrative support requirements of all team members should be considered to provide patients with the information and support required.

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.

Use of Long-Acting Injectable Antipsychotic in an Inpatient Unit of a Community Teaching Hospital. PSYCHIATRY JOURNAL 2019; 2019:8629030. [PMID: 31312652 PMCID: PMC6595334 DOI: 10.1155/2019/8629030] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/16/2019] [Revised: 05/15/2019] [Accepted: 05/29/2019] [Indexed: 11/17/2022]
Abstract
Background Individuals with Schizophrenia Spectrum Disorders (SSD) often experience significant impairment in educational, occupational, and psychosocial functioning. The clinical benefit of long-acting injectable antipsychotics (LAIs) in the management of patients with SSD is well established. SSD patients who are nonadherent to treatment have lower disease relapse and readmission rates when prescribed a LAI, compared to oral antipsychotics. Despite the reported advantages of LAIs, their prescription rates in clinical settings remain low. This pilot study aimed to determine the pattern of LAI prescription in psychiatric inpatients of a teaching community hospital in Brooklyn, New York. Methods A retrospective review of the charts of patients discharged from the psychiatric units of the hospital from September 1, 2017, through September 30, 2017, was conducted. Frequencies and proportions for demographic and disease-related characteristics were calculated. Pertinent continuous variables were recoded into categorical variables. Chi-square-tests or Fisher's exact tests were performed for categorical variables. The one-sample Shapiro-Wilk test (for sample size < 50) was used to check for the normality of distribution of continuous variables. Statistical significance was defined as p ≤ 0.05. Results Forty-three (70%) of the patients discharged from the inpatient unit during the study period had SSD and were eligible for a LAI. Their ages ranged from 20 to 71 years (mean = 41 years), and more than two-thirds were male. Less than half of the eligible patients (n = 19; 44%) were prescribed a LAI, most of whom were male (n=16; 84%). An association between age group (patients aged 41 years or younger) and LAI use was observed (p < 0.05), while gender, employment status, living arrangement, length of hospital stay, recent hospitalization, and cooccurring substance use disorder were not. Conclusion LAI prescription rate at the inpatient psychiatric unit of the hospital was marginally higher than those reported in most studies. Age appears to influence LAI use during the study period. Initiatives that increase LAI prescription rate for all eligible patients admitted to inpatient psychiatric unit should be encouraged.

Abstract
BACKGROUND Long-acting injectable antipsychotics (LAIs) are regarded as an important alternative to oral medication for patients with schizophrenia. However, LAIs remain under-utilized in clinical practice. AIMS The aims of this investigation were to 1) obtain information on patients' attitudes toward LAIs and 2) assess factors associated with patients' acceptance of LAIs, and 3) identify predictors of the discrepancy between patients and referring psychiatrists' opinions regarding the appropriateness for LAIs. METHODS Anonymized data were collected from a questionnaire distributed to 159 patients with schizophrenia and their referring psychiatrists at three psychiatric hospitals between February 2014 and July 2014. The patients completed an original questionnaire developed to evaluate their attitudes regarding LAIs. Regarding the appropriateness of LAI prescription, patients and their referring psychiatrists were asked to rate, on a 5-point scale, how appropriate they felt the depot prescription was for the patients. The participants also answered instruments to assess symptom severity, antipsychotic-induced extrapyramidal symptoms, functions, quality of life, and self-esteem levels. RESULTS Patients currently on LAIs have favorable attitudes toward LAIs with respect to side effects, relapse prevention, efficacy, pain, and cost. Expectation of relapse prevention was significantly associated with patients' acceptance of LAIs (answering that those drugs are appropriate for their own treatment). In addition, the discrepancy between the patients' and referring psychiatrists' opinions regarding the appropriateness of LAI treatment was significantly associated with symptom severity, expectation of relapse prevention, belief that LAIs are painful, and belief that LAIs offer a reduced range of antipsychotic choices. CONCLUSION Attitudes toward LAIs need to be considered when deciding whether to prescribe this formulation. Access to information on LAIs, including their benefit in relapse prevention, might enhance the acceptance and use of this formulation among patients with schizophrenia.

Abstract
INTRODUCTION Long-acting injectable (LAI) antipsychotic use may reduce healthcare resource utilization compared with oral antipsychotic use by improving adherence and reducing dosing frequency. Our goal was to examine treatment patterns, healthcare utilization, and costs among recently diagnosed schizophrenia patients receiving oral versus LAI antipsychotics. METHODS The MarketScan Multi-state Medicaid database was used to identify schizophrenia patients aged ≥ 18 years who received an LAI or oral antipsychotic between January 1, 2011 and December 31, 2014. Primary outcomes included treatment patterns such as adherence (measured as proportion of days covered-PDC), persistence, discontinuation, switching, and healthcare resource utilization and costs. Propensity score matching (PSM) was used to control for differences in baseline characteristics between the cohorts. Outcomes were assessed over a 12-month post-index period and compared between treatment cohorts. RESULTS After PSM, 2302 patients were included in each of the LAI and oral antipsychotics cohorts. There were no differences in PDC or therapy switching between the two cohorts. Compared with the oral cohort, patients receiving LAIs had lower discontinuation rates (46.1 vs. 61.6%, p < 0.001), fewer inpatient admissions (0.5 vs. 0.9, p < 0.001), hospital days (3.9 vs. 6.5, p < 0.001), and ER visits (2.4 vs. 2.9, p = 0.007), and a higher number of prescription fills (29.5 vs. 25.3, p < 0.001). Patients prescribed LAIs had lower monthly inpatient ($US4007 vs. 8769, p < 0.001) and ER visits costs ($682 vs. 891, p < 0.001) but higher monthly medication costs ($10,713 vs. $655, p < 0.001) compared with the oral cohort over the 12-month post-index period. Overall, both cohorts had similar total medical costs (LAI vs. oral: $24,988 vs. 23,887, p = 0.354) during the follow-up period. CONCLUSION Patients receiving LAIs were more likely to remain on medication compared with the oral group, which may account for reduced inpatient admissions. Hospitalization cost reductions offset the higher costs of LAI medications, resulting in no increase in total healthcare costs relative to oral antipsychotic use. FUNDING Alkermes Inc.

Is the risk of antipsychotic polypharmacy discontinuation dependent on the agents used? Psychiatry Res 2018; 263:238-244.

Abstract
This study assesses the risks and benefits of switching from two to one antipsychotic among participants on two non-clozapine oral antipsychotics, and among those on combinations involving either clozapine or an injectable antipsychotic. Ninety adult participants with schizophrenia or schizoaffective disorder were assigned to stay on polypharmacy or to switch to monotherapy. Half of these participants were receiving combinations of non-clozapine oral antipsychotics and half were receiving combinations involving either clozapine or an injectable antipsychotic. Participants were assessed every 60 days for one year. We examined differences in symptom and side effect trajectories as a function of group assignment and time for both medication groups. Participants who switched from two to one non-clozapine oral antipsychotic experienced significant increases in symptoms relative to stay participants. They also saw significant side effect benefits. Switch participants on combinations involving clozapine or an injectable antipsychotic did not differ over time from stay participants on either symptom or side effect measures. It appears that patients on these combinations can be safely switched to monotherapy. While there may be symptom related risks associated with switching patients on combinations of non-clozapine oral antipsychotics, there are significant health related benefits. Clozapine or injectable antipsychotic monotherapy are recommended options.

Abstract
Summary‘Depot antipsychotics' (‘long-acting injectable antipsychotic medications' or LAIs) are underused in the treatment of schizophrenia (including first episodes) and, possibly, of schizophrenia with comorbid substance use disorders. Patients' and clinicians' beliefs and attitudes, and service barriers, affect best practice and evidence-based care in LAI prescription. Poor medication adherence is a key reason for LAI prescription, but patients receiving LAIs may still relapse or experience significant side-effects. Patients' and clinicians' attitudes towards antipsychotic medication, as well as the quality of their recovery-focused relationship, are key factors in adherence. Clinicians should avoid a dichotomous ‘oralv. LAI’ choice: LAIs may have a place at various stages in the continuum of care and they should be one of the options discussed with any patient requiring long-term treatment, even early in the illness course. Many clinicians need better education about LAIs and greater familiarity with schizophrenia treatment guidelines.

Abstract
BACKGROUND Although many studies have discussed psychiatrists' attitudes toward long-acting injectable antipsychotics (LAIs), no previous study has focused on differences in preference based on the facilities in which the psychiatrists practiced. MATERIALS AND METHODS A pilot survey was conducted in a medical center in northern Taiwan, and a questionnaire was then distributed at the annual conference of the Taiwanese Society of Psychiatry in 2013. The questionnaire included general demographic data and preferences for the use of LAIs in different situations. RESULTS A total of 142 psychiatrists were included in our study. Among them, 114 were male (80.3%), and most practiced in general hospitals (n=110, 77.5%). We found that general hospital psychiatrists were more likely to prescribe LAIs for patients in the acute stage and with positive symptoms than were psychiatric hospital psychiatrists. General hospital psychiatrists also tended to prescribe LAIs at every time point of the disease. CONCLUSION General hospital psychiatrists were more likely to prescribe LAIs than those in psychiatric hospitals. Knowing the factors affecting psychiatrists' preferences may help us to develop a further study to explore "why" psychiatrists consider or do not consider LAIs in different facilities.

Abstract
PURPOSE Long-acting injectable antipsychotics (LAI) can optimize adherence for high-risk serious mental illness (SMI). This customized adherence-enhancement approach delivered by social worker interventionists was combined with LAI (CAE-L) of paliperidone palmitate for homeless, poorly adherent individuals with SMI. METHODS This 6-month prospective, uncontrolled trial of CAE-L in 30 recently homeless individuals with SMI assessed adherence using the Tablets Routine Questionnaire, injection frequency, and SMI symptoms measured by the Positive and Negative Syndrome Scale, Brief Psychiatric Rating Scale, and Clinical Global Impressions. The Social and Occupational Functioning Assessment Scale measured social function. Standardized scales assessed extrapyramidal effects. FINDINGS Patients' mean age was 43.6 (SD, 9.53) years, and they were mainly minorities (86.7% African American) and single/never married (72.4%). Rate of substance abuse within the past year was 40.0%, and rate of incarceration within the past 6 months was 32.1%. Four participants (13.3%) terminated the study prematurely. Customized adherence enhancement + LAI was associated with good adherence to LAI (92.9%) and improved adherence with oral drug as measured by Tablets Routine Questionnaire (P = 0.02). There were significant improvements in Positive and Negative Syndrome Scale (P < 0.01), Brief Psychiatric Rating Scale (P < 0.001), Clinical Global Impressions (P = 0.003), and Social and Occupational Functioning Assessment Scale (P = 0.005). There were no significant extrapyramidal effects. IMPLICATIONS While findings must be tempered by the methodological limitations, CAE-L seems associated with multiple domains of improvement in homeless/recently homeless individuals with SMI. Adverse effects limit tolerability in some individuals, and not all will remain engaged. However, LAI combined with a patient-centered behavioral approach can improve outcomes for some high-risk individuals with SMI.

Abstract
Studies have examined the differences in sociodemographic/clinical characteristics between patients on long-acting injectable (LAI) versus oral medications. However, most studies did not focus specifically on patients for whom LAIs would clearly be indicated. We performed a chart review of patients with schizophrenia or schizoaffective disorder. Patients were categorized as having an 'indication for an LAI' or not on the basis of their adherence history. Patients for whom an LAI was indicated and prescribed on discharge were then compared with similar patients for whom an LAI was not prescribed. Of 305 charts reviewed, consisting of 279 unique patients, 27.2% were judged to have an indication for an LAI (n=76), but only 32.9% of these (n=25) were discharged on an LAI. In the multiregression model, being African American, residing in a psychiatric residence, having a previous history of an LAI trial, and being treated with a higher antipsychotic dose were predictive of LAI prescription. It is important to focus on the population who are not likely to receive an LAI, but who have such indications for treatment.

Abstract
OBJECTIVE To explore the impact of the introduction of newer antipsychotic long-acting injections (LAIs) on trends in LAI prescribing and characteristics associated with initiation of LAIs in naturalistic conditions. METHODS The study was performed using reimbursement data from the French Insurance Healthcare system. Prescribing trends were investigated from 2007 to 2014 in 382,572 persons aged 18years and over. Characteristics associated with delay in transition from oral antipsychotic to LAIs were explored in a cohort of 6904 persons newly treated with an oral antipsychotic using multivariate survival analyses. RESULTS LAI prescribing rates slightly increased over the study period. The likelihood of being prescribed LAIs was stable for FGA LAIs (around 1.8 per 1000) (aOR=0.99, 95%CI 0.98-1.00) and increased for SGA LAIs from 0.5 to 1 per 1000 (aOR=1.11, 95%CI 1.08-1.14). In persons initiating an LAI (n=288), shorter transition from oral antipsychotic to LAI was independently predicted by male gender, younger age, dispensing of an oral SGA and a higher number of oral antipsychotics dispensed over the follow-up. Transition was longer in persons dispensed antidepressants or mood-stabilizers over the follow-up. Male gender, low income and higher number of antipsychotics were associated only with shorter transition to FGA LAIs, while initial prescription by a public practitioner, no mood-stabilizer dispensing and lack of somatic severe chronic condition were associated only with SGA LAIs dispensing. CONCLUSIONS It is of interest to explore whether similar prescribing trends are observed in other countries and to further assess the effectiveness of new LAIs in real-life conditions.

Abstract
BACKGROUND Antipsychotic medications are a central component of effective treatment for schizophrenia, but nonadherence is a significant problem for the majority of patients. Long-acting injectable (LAI) antipsychotic medications are a recommended treatment option for nonadherent patients, but evidence regarding their potential advantages has been mixed. Observational data on newer, second-generation LAI antipsychotic medications have been limited given their more recent regulatory approval and availability. OBJECTIVE To examine antipsychotic medication nonadherence, discontinuation, and rehospitalization outcomes in Medicaid patients receiving oral versus LAI antipsychotic medications in the 6 months after a schizophrenia-related hospitalization. METHODS The 2010-2013 Truven Health Analytics MarketScan Medicaid research claims database was used to identify adult patients with a recent history of nonadherence (prior 6 months) who received an oral or LAI antipsychotic medication within 30 days after an index schizophrenia-related hospitalization. Primary outcome measures were nonadherence (proportion of days covered less than 0.80), discontinuation (continuous medication gap ≥ 60 days), and schizophrenia-related rehospitalization, all in the 6 months after discharge. Descriptive analyses compared users of oral versus LAI antipsychotic medication on sociodemographic, clinical, and treatment characteristics. Logistic regressions were used to examine associations between use of oral versus LAI antipsychotics and each study outcome while controlling for observed differences in sample characteristics. All outcomes were compared at 3 levels of analysis: overall LAI class, LAI antipsychotic generation (first-generation [FGA] or second-generation [SGA] antipsychotics), and individual LAI agent (fluphenazine decanoate, haloperidol decanoate, risperidone LAI, and paliperidone palmitate). RESULTS Of the final sample, 91% (n = 3,428) received oral antipsychotics, and 9.0% (n = 340) received LAI antipsychotics after discharge. Slightly over half (n =183, 53.8%) of LAI users used an SGA LAI. A smaller percentage of patients receiving LAIs were nonadherent (51.8% vs. 67.7%, P less than 0.001); had a 60-day continuous gap in medication (23.8% vs. 39.4%, P less than 0.001); and were rehospitalized for schizophrenia (19.1% vs. 25.3%, P = 0.01) compared with patients receiving oral medications. The size of these differences was magnified when comparing SGA LAI users with users of oral antipsychotics for nonadherence. After controlling for all differences in measured covariates, LAI initiators had lower odds of being nonadherent (adjusted odds ratio [AOR] = 0.35, 95% CI = 0.27-0.46, P less than 0.001) and of having continuous 60-day gaps (AOR = 0.45, 95% CI = 0.34-0.60, P less than 0.001) when compared with patients receiving oral medications. Both FGA and SGA LAI users had lower odds of nonadherence compared with patients receiving oral antipsychotics. Similarly, FGA LAI users (AOR = 0.58, 95% CI = 0.40-0.85, P = 0.005) and SGA LAI initiators (AOR = 0.34, 95% CI =0.23-0.51, P less than 0.001) had lower odds of a 60-day continuous gap compared with patients receiving oral antipsychotics. Compared with those receiving oral antipsychotics, LAI initiators also had lower odds of rehospitalization (AOR = 0.73, 95% CI = 0.54-0.99, P = 0.041); however, when examined separately, only patients receiving SGA LAIs (AOR = 0.59, 95% CI = 0.38-0.90, P = 0.015) and not FGA LAIs (AOR = 0.90, 95% CI = 0.60-1.34, P = 0.599) had a statistically significant reduction in odds of rehospitalization. Among individual LAIs, odds of rehospitalization only among initiators of paliperidone palmitate were statistically different from those among users of oral antipsychotics (AOR = 0.53, 95% CI = 0.30-0.94, P = 0.031). While odds of rehospitalization were 33% lower among patients receiving risperidone LAI compared with those receiving oral antipsychotics, the estimate did not reach statistical significance (AOR = 0.67, 95% CI = 0.37-1.22, P = 0.194). CONCLUSIONS This claims-based analysis of posthospitalization adherence and rehospitalization outcomes in Medicaid patients with schizophrenia adds to the growing real-world evidence base of the benefits of LAI antipsychotic medications in routine clinical practice, particularly with regard to second-generation LAIs. As new SGA formulations become available for long-acting use, real-world studies with larger sample sizes will be needed to further delineate their potential advantages in terms of clinical outcomes and costs.

Abstract
Second-generation antipsychotics (SGAs) are a mainstay in the treatment of patients with schizophrenia. However, continuity in intake of the prescribed medication has been one of the greatest challenges in these patients. One option to improve medication adherence is to prescribe depot or long-acting injectable formulations (LAIs) of antipsychotics. Following risperidone, several other SGAs have been introduced as LAIs. Olanzapine pamoate, paliperidone palmitate, and aripiprazole are the new-generation LAIs, which are available for 2- to 4-week intervals of application in many countries. The literature shows a clear advantage of these drugs over placebo regarding symptom reduction and relapse prevention. LAIs show a similar safety profile to oral formulations of the relevant drug, with the exception of olanzapine pamoate, which can lead to rare cases of post-injection delirium/sedation syndrome (PDSS). PDSS is characterized by heavy sedation (possibly including coma) and/or delirium after injection. During PDSS events, patients show higher plasma concentrations of olanzapine, leading to the assumption that unintended partial intravascular injection or blood vessel injury during the injection is causative of PDSS. Therefore, a risk-management plan proposing an observation period of 3 h was introduced. In August 2013, a new proposal by the European Medicines Agency terminated the requirement to accompany these patients to their next destination, although this requirement remains in place according to US FDA recommendations.

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.

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.

Comparison of olanzapine long-acting injection and oral olanzapine: a 2-year, randomized, open-label study in outpatients with schizophrenia. J Clin Psychopharmacol 2014; 34:426-34.

Abstract
We compared long-term treatment effectiveness of monthly olanzapine long-acting injection (LAI) with that of oral olanzapine. Outpatients with 2 or more episodes of psychotic worsening in the past 24 months with Positive and Negative Syndrome Scale total score of lower than 70 were randomized to 405 mg/4 weeks of olanzapine LAI (n = 264) or 10 mg/d of oral olanzapine (n = 260) for 2 years of open-label treatment. Dosing thereafter was flexible (150-405 mg/4 weeks of LAI vs 5-20 mg/d of oral). Primary outcome was time to all-cause discontinuation. At baseline, patients were clinically stable (mean Positive and Negative Syndrome Scale total score of 57). Seventeen percent of patients had been psychiatrically hospitalized in the previous 6 months, and 4.6% were rated nonadherent in the month before study entry. The groups did not differ significantly in median time to all-cause discontinuation (645 days for LAI, 678 days for oral; P = 0.61), discontinuation rate (53.8% for LAI, 51.2% for oral; P = 0.60), or relapse rate (20.1% for LAI, 18.5% for oral; P = 0.66). Postbaseline psychiatric hospitalization rate was low for both groups (7.6% for LAI, 9.2% for oral), but mean hospitalization duration was significantly longer for oral patients (1.80 days [20 for those hospitalized] vs 0.43 days [6 for those hospitalized], P = 0.02). There were no clinically significant group differences in adverse events or safety measures. No post-injection delirium/sedation syndrome events occurred. In conclusion, olanzapine LAI and oral olanzapine were similarly effective and well tolerated for up to 2 years of treatment in patients with schizophrenia. Treatment discontinuation for olanzapine LAI was similar to that of oral olanzapine, despite the 3-hour post-injection observation period and other precautionary procedures related to risk of post-injection delirium/sedation syndrome.

Abstract
The Practice Research Network (PRN) was established in 1993 to bridge the gap between the science base and the clinical practice of psychiatry by expanding the generalizability of findings and involving clinicians in the development and conduct of research. It began as a nationwide network of psychiatrists and has evolved to conduct large-scale, clinical and policy research studies using randomly selected samples of psychiatrists from the AMA Physician Masterfile. This paper provides an overview of major PRN initiatives and the impact of these studies. It describes the benefits to clinicians of participating in PRN research, as well as strategies developed to address key challenges.

Abstract
PURPOSE In patients with schizophrenia, nonadherence to prescribed medications increases the risk of patient relapse and hospitalization, key contributors to the costs associated with treatment. The objectives of this review were to evaluate the impact of nonadherence to pharmacotherapy in patients with schizophrenia as it relates to health care professionals, particularly social workers, and to identify effective team approaches to supporting patients based on studies assessing implementation of assertive community treatment teams. MATERIALS AND METHODS A systematic review of the medical literature was conducted by searching the Scopus database to identify articles associated with treatment adherence in patients with schizophrenia. Articles included were published from January 1, 2003, through July 15, 2013, were written in English, and reported findings concerning any and all aspects of nonadherence to prescribed treatment in patients with schizophrenia. RESULTS Of 92 unique articles identified and formally screened, 47 met the inclusion criteria for the systematic review. The burden of nonadherence in schizophrenia is significant. Factors with the potential to affect adherence include antipsychotic drug class and formulation, patient-specific factors, and family/social support system. There is inconclusive evidence suggesting superior adherence with an atypical versus typical antipsychotic or with a long-acting injectable versus an oral formulation. Patient-specific factors that contribute to adherence include awareness/denial of illness, cognitive issues, stigma associated with taking medication, substance abuse, access to health care, employment/poverty, and insurance status. Lack of social or family support may adversely affect adherence, necessitating the assistance of health care professionals, such as social workers. Evidence supports the concept that an enhanced team-oriented approach to managing patients with schizophrenia improves adherence and supports corresponding reductions in relapse rates, inpatient admissions, and associated costs. CONCLUSION Optimization of medication and involvement of caregivers are important to promoting adherence. A multidisciplinary team approach may be invaluable in identifying barriers to adherence and helping schizophrenia patients overcome them.

Abstract
Long-acting injectable (depot) antipsychotics are one approach in the management of individuals with schizophrenia. Since the introduction of risperidone long-acting injection in 2003, three additional second-generation antipsychotics have become available in a long-acting injectable formulation: paliperidone, olanzapine and aripiprazole. Although these different depot options can help with adherence and thus encourage better treatment outcomes, they differ in terms of specific indications, approved injection sites, needle gauge, injection volume, injection interval, requirements for oral supplementation, availability of prefilled syringes, storage needs and postinjection observation period, as well as potential drug-drug interactions and commonly encountered adverse reactions. After a review of the evidence base, guidance is offered on the appropriate selection among the long-acting injectable formulations of both first and second-generation antipsychotics.

Abstract
BACKGROUND Treatment nonadherence in people with schizophrenia is associated with relapse and homelessness. Building on the usefulness of long-acting medication and our work in psychosocial interventions to enhance adherence, we conducted a prospective uncontrolled trial of customized adherence enhancement (CAE) plus long-acting injectable antipsychotic (LAI) using haloperidol decanoate in 30 homeless or recently homeless individuals with DSM-IV-defined schizophrenia or schizoaffective disorder. METHOD Participants received monthly CAE and LAI (CAE-L) for 6 months. Primary outcomes were adherence, as measured by the Tablets Routine Questionnaire, and housing status. Secondary outcomes included psychiatric symptoms, functioning, side effects, and hospitalizations. The study was conducted from July 2010 to December 2012. RESULTS The mean age of participants was 41.8 years (SD = 8.6); they were mainly minorities (90%, n = 27 African-American) and mainly single/never married (70%, n = 21). Most (97%, n = 29) had past or current substance abuse and had been incarcerated (97%, n = 29). Ten individuals (33%) terminated the study prematurely. CAE-L was associated with good adherence to LAI (at 6 months, 76%) and dramatic improvement in oral medication adherence, which changed from missing 46% of medication at study enrollment to missing only 10% at study end (P = .03). There were significant improvements in psychiatric symptoms (P < .001) and functioning (P < .001). Akathisia was a major side effect with LAI. CONCLUSIONS While interpretation of findings must be tempered by the methodological limitations, CAE-L appears to be associated with improved adherence, symptoms, and functioning in homeless or recently homeless individuals with schizophrenia or schizoaffective disorder. Additional research is needed on effective and practical approaches to improving health outcomes for homeless people with serious mental illness.

Abstract
OBJECTIVE Assessment of factors influencing antipsychotic prescription fills in the early phase of schizophrenia or schizoaffective disorder. METHODS We used the Swedish Patient Register to identify patients younger than 45 years with a first hospitalization for schizophrenia or schizoaffective disorder between 2006 and 2007 (904 patients). Data on medication were obtained from the Prescribed Drug Register. Filling a prescription of an antipsychotic drug after discharge was used to estimate medication adherence. In Cox regression models, we studied sex, country of birth, metropolitan residence, educational level, age, duration of hospitalization, history of substance use disorder, and previous use of antipsychotic drugs as predictors for antipsychotic fills. RESULTS Among all patients, 53.1% (95% confidence interval [CI] 49.9%-56.4%) had filled an antipsychotic prescription within 1 week from discharge. After 6 months, the proportion had increased to 80.2% (95% CI, 77.4%-82.8%) with no further increase thereafter. Prescription filling of an antipsychotic drug was primarily associated with antipsychotic use before the hospitalization (hazard ratio, 1.64; 95% CI, 1.33-2.03; for patients with access to antipsychotic drugs at admission compared with no previous use) and with longer hospitalization (hazard ratio, 1.60; 95% CI, 1.27-2.02 for 15-28 days compared with shorter hospitalization). CONCLUSIONS Among patients who filled a prescription of an antipsychotic drug after discharge, the majority did so within 1 week. Previous adherent use of antipsychotic drugs and longer hospitalization may be predictors of primary adherence to antipsychotic drug treatment in schizophrenia or schizoaffective disorder.

Abstract
INTRODUCTION Olanzapine pamoate is one of three second-generation antipsychotics available as depot medication. While non-adherence is a major problem in the treatment of schizophrenia, olanzapine pamoate can improve adherence, though its use is limited by its safety profile. AREAS COVERED The review covers data on efficacy with a focus on tolerability and safety of olanzapine pamoate using the known databases including PubMed, Psychinfo and Embase using keywords. Relevant websites were also reviewed. EXPERT OPINION Olanzapine is an efficacious antipsychotic that can be used in its oral and depot formula (olanzapine pamoate) for the treatment of patients with schizophrenia. It has demonstrated superiority over conventional and some other atypical antipsychotics, with both formulas having comparable low rates of motor side effects. The side effects on body weight and glucose homeostasis are also similar in both formulas and limit its use. The only clear difference regarding side effects is 'the risk that 0.07% of injections in preclinical trials have led to a post-injection delirium/sedation syndrome event which requires a risk management plan'. Especially in outpatients this could cause inconveniences that should be overcome by offering, for example, psychological therapies or psychoeducation to effectively use the time when patients have to remain in the healthcare facilities.

Abstract
Depot formulations are not widely used in everyday practice. This study aimed to assess psychiatrists' attitudes toward the use of long-acting injectable (LAI) antipsychotics in schizophrenia. We interviewed 113 French psychiatrists about the factors that influenced their prescription of LAI antipsychotics. Multidimensional and cluster analyses were used to detect correlations. The most important factor against the use of LAI antipsychotics is a sufficient estimated compliance with the oral formulation. For first-generation LAI, the main factor is the risk for extrapyramidal symptoms; and for second-generation LAI, it is the unavailability of the equivalent oral formulation. Four factors incite the psychiatrists to prescribe LAI. Two different clusters of patients can also be identified. Most factors influencing the clinicians' attitudes toward the use of LAI antipsychotics are shared in many countries. Conversely, some attitudes related to organizational aspects, particularly the relevance of health care costs, may vary from one country to another.

Abstract
OBJECTIVE To review the evidence for the role of long-acting injectable (LAI) antipsychotics (APs), especially the second-generation AP (SGA) LAIs, in the treatment of schizophrenia and to discuss the use rates of LAIs in Canada. METHOD A search of online medical databases was conducted of the published literature (1995-2012) of the effects of LAIs on the domains of remission, adherence, relapse, and hospitalization. Results obtained from randomized controlled trials (RCTs), systematic reviews, meta-analyses, and large-scale observational studies were included. Expert consensus data were also solicited on LAI use within a Canadian context. RESULTS While the efficacy of LAIs, compared with placebo, is well established, the evidence from RCTs is equivocal for any specific advantage for SGA LAIs, compared with oral medications, probably owing to challenges in conducting such RCTs. Evidence from methodologically less rigorous studies and from clinical practice suggests some advantages in achieving and maintaining remission, risk of relapse, and hospitalization. The rate of LAI (first-generation AP and SGA) use from published outpatient studies is low at 6.3% in Canada, compared with 15% to 80% worldwide. However, there is a relatively high rate of use in specific early psychosis programs and in conjunction with community treatment orders in Canada. CONCLUSIONS LAIs are at least as effective as oral APs in the treatment of psychotic disorders. The former may have specific advantages for patients who demonstrate covert nonadherence. The underuse of LAIs in Canada needs to be better understood and addressed.

Abstract
OBJECTIVE This study compared healthcare resource usage and costs before and after initiating LAI antipsychotics among Medicaid-insured schizophrenia patients. METHODS Schizophrenia patients ≥13 years of age initiating LAI antipsychotics were identified from the Thomson Reuters MarketScan® Research Medicaid database between 7/1/2005 and 6/30/2010. Patients were required to have 6 months of continuous medical/prescription drug coverage prior to LAI initiation (baseline period) and during a variable follow-up period. Annualized healthcare resource usage and costs for the baseline and follow-up periods were determined and compared. RESULTS Among 5694 eligible patients, 55% were male and 45% were female, and the majority of the population was between the ages of 18-55 (86%). The study population had low general comorbidity, as assessed by the Charlson Comorbidity Index (CCI). Diabetes (17%) and chronic pulmonary disease (14%) were the most prevalent comorbidities. In comparison to the baseline period, during the follow-up period (mean duration = 25.7 months) the mean number of hospitalizations, all cause (1.52 ± 2.41 vs 0.70 ± 1.61, p < 0.001) and schizophrenia-related (1.21 ± 2.04 vs 0.57 ± 1.41, p < 0.001) declined as well as hospital lengths of stay (all cause: 14.77 ± 28.61 vs 5.75 ± 16.26 days, p < 0.001; schizophrenia-related: 12.39 ± 25.86 vs 4.67 ± 13.54 days, p < 0.001). As a result, annualized hospital payments were much lower (all cause: $16,249 ± $36,404 vs $7380 ± $21,087, p < 0.001; schizophrenia-related: $13,388 ± $31,614 vs $5645 ± $15,767, p < 0.001). LIMITATIONS This study attempted to minimize the impact of differences in patient characteristics by having patients serve as their own controls in the before vs after comparison, however one still may not be able to account for all confounders in this non-randomized study population. CONCLUSION For patients with schizophrenia who initiate LAI antipsychotic therapy, there is an improvement in disease management based on fewer hospitalizations for relapses, which is also associated with a marked reduction in healthcare costs.

Abstract
OBJECTIVE To compare hospitalizations and incidence of relapses among patients with schizophrenia initiating long-acting injectable (LAI) antipsychotics vs oral antipsychotics. METHODS Patients with schizophrenia initiating LAI antipsychotics or oral antipsychotics (index events) were identified from large databases (MarketScan; Truven Health Analytics, CA), containing commercial and Medicare healthcare claims and their pre-index (12-month baseline period) and post-index (12-month follow-up period) hospitalizations and relapse rates were compared. Descriptive and bivariate statistics were utilized to compare demographics, clinical characteristics, and hospital resource usage among cohorts. Multivariate analysis was used to evaluate the impact of initiating LAI vs oral antipsychotics on differences in the number of hospitalizations and length of stay (LOS) between follow-up and baseline periods. RESULTS Commercially insured patients initiating LAI antipsychotics (n = 394) had significant reductions in inpatient healthcare usage after initiating antipsychotic therapy: mean number (±standard deviation) of all cause hospitalizations (1.60 ± 1.66 vs 0.70 ± 1.20, p < 0.001), LOS (16.9 ± 20.7 vs 6.6 ± 14.4 days, p < 0.001), schizophrenia-related hospitalizations (1.03 ± 1.26 vs 0.43 ± 0.86, p < 0.001), associated LOS (12.3 ± 17.7 vs 4.8 ± 12.8 days, p < 0.001). Patients initiating LAI vs oral antipsychotics (n = 2610) had significantly greater reductions during the follow-up period vs baseline period in the mean number of all cause hospitalizations (-0.90 ± 1.77 vs 0.02 ± 1.49, p < 0.001), LOS (-10.3 ± 23.2 vs 0.7 ± 16.7 days, p < 0.001), schizophrenia-related hospitalizations (-0.60 ± 1.37 vs 0.05 ± 0.99, p < 0.001) and associated LOS (-7.5 ± 20.7 vs 0.6 ± 12.5 days, p < 0.001). These results were further supported by multivariate analyses in which patient characteristics were taken into consideration. LIMITATIONS This study attempted to minimize the impact of differences in patient characteristics by having patients serve as their own controls in the before vs after comparison followed by multivariate regressions, however one still may not be able to account for all confounders in this non-randomized study population. CONCLUSION Patients with schizophrenia who initiated LAI vs oral antipsychotics experienced reductions in hospitalizations and schizophrenia relapses after drug initiation, which may be indicative of improved disease management.

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.

Abstract
Improving outcomes in schizophrenia generally requires an improvement in medication adherence. One of the most effective interventions to improve adherence is the use of depot formulations of antipsychotic medications. A new depot aripiprazole formulation for the treatment of schizophrenia will be available soon. A review of all publically available information on depot aripiprazole as of November 2012 was performed. One peer-reviewed study on depot aripiprazole is published, and the remainder of the data were presented at international scientific meetings. Depot aripiprazole appears to be both safe and effective in the long-term treatment of schizophrenia.

Abstract
OBJECTIVE This study evaluated the effect of race-ethnicity and geography on the adoption of a pharmacological innovation (long-acting injectable risperidone [LAIR]) among Medicaid beneficiaries with schizophrenia as well as the contribution of geographic location to observed racial-ethnic disparities. METHODS The data source was a claims data set from the Florida Medicaid program for the 2.5-year period that followed the launch of LAIR in the U.S. market. Study participants were beneficiaries with schizophrenia who had filled at least one antipsychotic prescription during the study period. The outcome variable was any use of LAIR; model variables were need indicators and random effects for 11 Medicaid areas, which are multicounty units used by the Medicaid program to administer benefits. Adjusted probability of use of LAIR for blacks and Latinos versus whites was estimated with logistic regression models. RESULTS The study cohort included 13,992 Medicaid beneficiaries: 25% of the cohort was black, 37% Latino, and 38% white. Unadjusted probability of LAIR use was lower for Latinos than whites, and use varied across the state's geographic areas. Adjustment for need confirmed the unadjusted finding of a disparity between Latinos and whites (odds ratio=.58, 95% confidence interval=.49-.70). The inclusion of geographic location in the model eliminated the Latino-white disparity but confirmed the unadjusted finding of geographic variation in adoption. CONCLUSIONS Within a state Medicaid program, the initial finding of a disparity between Latinos and whites in adopting LAIR was driven by geographic disparities in adoption rates and the geographic concentration of Latinos in a low-adoption area. Possible contributors and implications of these results are discussed.

Abstract
OBJECTIVE There has been concern that racial minorities are disproportionately prescribed long-acting injectable antipsychotic drugs. METHOD Comprehensive administrative data and clinician survey were used to identify all patients with a DSM-IV diagnosis of schizophrenia who received long-acting antipsychotic prescriptions from July 2009 to June 2010 at a community mental health center. Charts were reviewed retrospectively to validate long-acting antipsychotic prescription (eg, medication, dosage) and merged with administrative data from all center patients documenting sociodemographic characteristics (ie, age, race, gender) and comorbid diagnoses. We used bivariate χ2, t tests, and multivariate logistic regression to compare the subsample of patients receiving long-acting injectable drugs (n = 102) to patients not receiving long-acting injectable drugs (n = 799) who were diagnosed with schizophrenia for the same period. RESULTS White patients were significantly less likely to receive long-acting antipsychotic prescriptions than minority patients (OR = 0.52, P < .007); ie, nonwhites were 1.89 times more likely to receive such drugs. Age, gender, and comorbid diagnoses, including substance abuse, were unrelated to long-acting injectable prescription, and race/ethnicity was not associated with use of specific agents (haloperidol decanoate, fluphenazine decanoate, or risperidone microspheres) (P = .73). CONCLUSIONS Racial minorities are more likely than other patients with schizophrenia to receive long-acting injectionable antipsychotics, a finding that suggests their prescribers may consider them less adherent to antipsychotic prescriptions.

Abstract
These guidelines from the British Association for Psychopharmacology address the scope and targets of pharmacological treatment for schizophrenia. A consensus meeting, involving experts in schizophrenia and its treatment, reviewed key areas and considered the strength of evidence and clinical implications. The guidelines were drawn up after extensive feedback from the participants and interested parties, and 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. The practice recommendations presented are based on the available evidence to date, and seek to clarify which interventions are of proven benefit. It is hoped that the recommendations will help to inform clinical decision making for practitioners, and perhaps also serve as a source of information for patients and carers. They are accompanied by a more detailed qualitative review of the available evidence. The strength of supporting evidence for each recommendation is rated.

Abstract
OBJECTIVE To compare, from the perspective of third-party payers in the United States health care system, the cost-effectiveness of olanzapine long-acting injection (LAI, depot) with alternative antipsychotic agents including risperidone-LAI, paliperidone-LAI, haloperidol-LAI, and oral olanzapine, in the treatment of patients with schizophrenia who have been non-adherent or partially adherent with oral antipsychotics. RESEARCH DESIGN AND METHODS A 1-year micro-simulation economic decision model was developed to simulate the dynamics of usual care of patients with schizophrenia who continue, discontinue, switch, or restart their medication. The model uses a range of clinical and cost parameters including adherence levels, relapse with and without hospitalization, quality-adjusted life years (QALYs), treatment discontinuation rates by reason, treatment-emergent adverse events, suicide, health care resource utilization, and direct health care costs. Published medical literature and a clinical expert panel were used to develop baseline model assumptions. OUTCOME MEASURES Key model outputs include annual total direct cost (US$) per treatment and incremental cost-effectiveness values per additional QALY gained. RESULTS Model results found that the olanzapine-LAI treatment strategy was more effective (greater QALYs) and less costly than risperidone-LAI, paliperidone-LAI, and haloperidol-LAI. In addition, olanzapine-LAI was both more effective and more costly, with an estimated incremental cost/QALY of $26,824 compared to oral olanzapine. The base-case and multiple sensitivity analyses found olanzapine-LAI to remain within acceptable cost-effective ranges (<$50,000) in terms of incremental cost/QALY gained. CONCLUSIONS This micro-simulation model finds the olanzapine-LAI treatment strategy to result in better effectiveness and to be a cost-effective alternative compared to oral olanzapine and the LAI formulations of risperidone, paliperidone, and haloperidol in the treatment of non-adherent and partially adherent patients with schizophrenia in the United States. A key limitation is the assumption how LAI therapies compare to oral counterparts due to sparse head-to-head data. Further research is needed to verify baseline assumptions.
