A Hybrid Type 1 trial of a multi-component mHealth intervention to improve post-hospital transitions of care for patients with serious mental illness: Study protocol. Contemp Clin Trials 2024; 139:107481. [PMID: 38431134 PMCID: PMC10960682 DOI: 10.1016/j.cct.2024.107481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/18/2023] [Accepted: 02/28/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND The transition from acute (e.g., psychiatric hospitalization) to outpatient care is associated with increased risk for rehospitalization, treatment disengagement, and suicide among people with serious mental illness (SMI). Mobile interventions (i.e., mHealth) have the potential to increase monitoring and improve coping post-acute care for this population. This protocol paper describes a Hybrid Type 1 effectiveness-implementation study, in which a randomized controlled trial will be conducted to determine the effectiveness of a multi-component mHealth intervention (tFOCUS) for improving outcomes for adults with SMI transitioning from acute to outpatient care. METHODS Adults meeting criteria for schizophrenia-spectrum or major mood disorders (n = 180) will be recruited from a psychiatric hospital and randomized to treatment-as-usual (TAU) plus standard discharge planning and aftercare (CHECK-IN) or TAU plus tFOCUS. tFOCUS is a 12-week intervention, consisting of: (a) a patient-facing mHealth smartphone app with daily self-assessment prompts and targeted coping strategies; (b) a clinician-facing web dashboard; and, (c) mHealth aftercare advisors, who will conduct brief post-hospital clinical calls with patients (e.g., safety concerns, treatment engagement) and encourage app use. Follow-ups will be conducted at 6-, 12-, and 24-weeks post-discharge to assess primary and secondary outcomes, as well as target mechanisms. We also will assess barriers and facilitators to future implementation of tFOCUS via qualitative interviews of stakeholders and input from a Community Advisory Board throughout the project. CONCLUSIONS Information gathered during this project, in combination with successful study outcomes, will inform a potential tFOCUS intervention scale-up across a range of psychiatric hospitals and healthcare systems.

Systematic Review of Real-World Treatment Patterns of Oral Antipsychotics and Associated Economic Burden in Patients with Schizophrenia in the United States. Adv Ther 2022; 39:3933-3956. [PMID: 35844007 PMCID: PMC9402774 DOI: 10.1007/s12325-022-02232-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 06/17/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Schizophrenia is a chronic mental disorder associated with substantial morbidity and mortality affecting 0.25-1.6% of adults in the USA. Antipsychotic treatment is the standard of care for schizophrenia, but real-world treatment patterns and associated costs have not been systematically reviewed. OBJECTIVE We conducted a systematic review to summarize treatment patterns and associated costs related to oral antipsychotic treatment of patients with schizophrenia in the USA. DATA SOURCES We searched Medline (via PubMed) and Embase to identify relevant observational studies published from January 1, 2008, to June 1, 2018; costs were converted to 2018 US dollars. STUDY ELIGIBILITY Observational, real-world studies reporting on patterns of treatment and/or associated costs for adult patients with schizophrenia treated with oral antipsychotics in the USA were included. RESULTS Eighty-one studies were identified. Frequently prescribed oral second-generation antipsychotics were olanzapine (up to 50.9%), risperidone (up to 40.0%), and quetiapine (up to 30.7%). Suboptimal adherence was common across studies. Antipsychotic switching occurred in about half of patients, while antipsychotic combination therapy occurred in nearly 30%; all were associated with increased medication-related costs. Mean annual direct medical costs differed by treatment, with reported costs of $17,115 to $26,138 for patients treated with olanzapine, $18,395 for risperidone, and $17,656 to $28,101 for quetiapine. LIMITATIONS This systematic review is limited by the variations in definitions of schizophrenia-related clinical terms used between studies and by the inclusion of studies focused on only the US health care system. CONCLUSIONS In the treatment of schizophrenia, suboptimal adherence, antipsychotic switching, and antipsychotic augmentation were all associated with high costs of care in comparison to patients who were adherent and did not require antipsychotic switching or augmentation. These findings illustrate the need for the development of new treatments that address efficacy and adherence challenges of currently available therapies.

Long-Term Antipsychotic Effectiveness and Comparison of the Efficacy of Monotherapy and Polypharmacy in Schizophrenia: A 3-Years Follow-Up “Real World” Study in China. Front Pharmacol 2022; 13:860713. [PMID: 35770081 PMCID: PMC9234304 DOI: 10.3389/fphar.2022.860713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2022] [Accepted: 05/16/2022] [Indexed: 01/10/2023] Open
Abstract
Background: Discontinuation of antipsychotic treatment is a common problem in patients with schizophrenia and could reduce the effectiveness of treatment. Time to discontinuation (TTD) is one of the indicators of compliance and may also be an effective indicator of medication efficacy. The aim of the study was to compare the clinical effectiveness of quetiapine, olanzapine, risperidone, and aripiprazole in the real-world treatment of schizophrenia with 3-years follow-up.Method: A multi-center, open, cohort, prospective, real-world study was conducted. 706 patients were analyzed without intervention in medication selection and use, followed up for 3 years. Kaplan-Meier survival curves were used to draw the treatment discontinuation rates (TDR) curves at each time point. Cox proportional hazard regression model was used to assess the relative risk of TTD of antipsychotics.Results: There was a significant difference among monotherapy groups in all-cause antipsychotic treatment discontinuation (p = 0.0057). Among the four medications, the TDR of risperidone was the highest. Compared with polypharmacy, except for aripiprazole, the TDR of other three monotherapy medications were lower than that of polypharmacy, and olanzapine was statistically different (p = 0.0325). The cox regression analysis showed that after correction of Hochberg with multiple tests, only olanzapine had a relative risk lower than risperidone (p < 0.0083).Conclusions: The findings indicated that risperidone monotherapy and polypharmacy had the highest TDR and the shortest TTD. Olanzapine monotherapy had a relative risk lower than risperidone and was superior to polypharmacy.

Abstract
PURPOSE Antipsychotic long-acting injections (AP-LAIs) are indicated for patients affected by schizophrenia especially those with poor treatment adherence. PATIENTS AND METHODS To compare paliperidone palmitate 3-monthly (PP3M), paliperidone palmitate one-monthly (PP1M) and haloperidol decanoate (HAL-D) treatment, we enrolled 90 patients with schizophrenia treated in Mental Health Center with one of the three AP-LAIs for at least six months and followed them for another 6 months. At 6 and 12 months of treatment we administered Clinical Global Impression-Severity, Global Assessment of Functioning and World Health Organization Quality of Life-26 items (WHOQOL-BREF). At 1-year treatment, we evaluated relapses (psychiatric hospitalizations and urgent consultations), side effects and drop-outs. RESULTS We did not highlight any statistically significant difference among the three treatments in relapses and scale scores. Weight increase was significantly higher in PP1M and PP3M groups. Twelve patients (13.3%) discontinued AP-LAI. At 1-year AP-LAI treatment, 69% of patients rated quality of life as "good" or "very good" and 71% declared themselves to be "satisfied" or "very satisfied". CONCLUSION HAL-D, PP1M and PP3M 1-year treatments were similarly effective in preventing relapses and improving quality of life and health satisfaction. All discontinuations in the new 3-monthly antipsychotic treatment were caused by patient refusal to continue it.

Abstract
OBJECTIVE Effectiveness of antipsychotic drugs is inferred from relatively small randomized clinical trials conducted with carefully selected and monitored participants. This evidence is not necessarily generalizable to individuals treated in daily clinical practice. The authors compared the clinical effectiveness between all oral and long-acting injectable (LAI) antipsychotic medications used in the treatment of schizophrenia in the U.S. Department of Veterans Affairs (VA) health care system. METHODS This was an observational study utilizing VA pharmacy data from 37,368 outpatient veterans with schizophrenia. Outcome measures were all-cause antipsychotic discontinuation and psychiatric hospitalizations. Oral olanzapine was used as the reference group. RESULTS In multivariable analysis, clozapine (hazard ratio=0.43), aripiprazole long-acting injectable (LAI) (hazard ratio=0.71), paliperidone LAI (hazard ratio=0.76), antipsychotic polypharmacy (hazard ratio=0.77), and risperidone LAI (hazard ratio=0.91) were associated with reduced hazard of discontinuation compared with oral olanzapine. Oral first-generation antipsychotics (hazard ratio=1.16), oral risperidone (hazard ratio=1.15), oral aripiprazole (hazard ratio=1.14), oral ziprasidone (hazard ratio=1.13), and oral quetiapine (hazard ratio=1.11) were significantly associated with an increased risk of discontinuation compared with oral olanzapine. No treatment showed reduced risk of psychiatric hospitalization compared with oral olanzapine; quetiapine was associated with a 36% worse outcome in terms of hospitalizations compared with olanzapine. CONCLUSIONS In a national sample of veterans with schizophrenia, those treated with clozapine, two of the LAI second-generation antipsychotics, and antipsychotic polypharmacy continued the same antipsychotic therapy for a longer period of time compared with the reference drug. This may reflect greater overall acceptability of these medications in clinical practice.

Abstract
Introduction: Pregnant women and fetuses are more likely than ever to be exposed to antipsychotic drugs (APs) during pregnancy and postpartum period. Second-generation APs (SGA) are increasingly used among women in reproductive age. Key outcomes (i.e., congenital malformations, pregnancy and maternal outcomes, neonatal/infant risks, and developmental/long-term outcomes) following the exposure to APs remain limited in number and size and yield of inconsistent findings overall, particularly regarding long-acting injectable AP (LAI-APs) formulations.Areas covered: The review aims at providing a summary of current knowledge on potential risks and safety profile of LAI-APs during pregnancy and breastfeeding, specifically focusing on SGA.Expert opinion: The management of safety and tolerability of long-acting injectable AP (LAI-APs) is far from having solid scientific evidence. In fact, due to ethical reasons, there is a lack of randomized clinical trials that limits the reliability and generalizability of the available data on LAI-APs safety profile during the perinatal period, being limited in the scientific literature only to isolated case reports. Therefore, it seems to be important for the future pathways to perinatal mental health care, providing a network of specialized clinicians and systematically collecting data of pregnant/puerperal women on oral and/or LAI APs-therapy about mother and infant outcomes.

Abstract
Schizophrenia often requires long-term treatment with antipsychotic medication. This study aims to measure the continuity of antipsychotic treatment over the course of illness in schizophrenia, as well as factors involved in the interruption of treatment. For this, we followed up a national cohort of first-episode psychosis patients in Finland for up to 18 years. Stratified Cox proportional hazards regressions were conducted for "within-participant" risk of discontinuation of subsequent treatments compared to the first, and by specific antipsychotic compared to oral olanzapine, the most prescribed antipsychotic in this cohort. Adjusted hazard ratios (aHRs) and 95% confidence intervals (95% CIs) were calculated. Among 3343 participants followed up for a mean of 8 years (SD = 4.93), the median number of continuous treatment episodes was 6 (interquartile range [IQR] = 3-11) with a median duration of 11.4 months (IQR = 5.3-25.6). In the first year after diagnosis, the incidence rate of treatment discontinuation was 30.12 (95% CI = 29.89-30.35) events per 100 participant-years, decreasing to 8.90 (95% CI = 8.75-9.05) in the 10th year. The risk of discontinuation progressively decreased over successive treatment episodes (aHR = 0.30; 95% CI = 0.20-0.46 for episodes after the 15th compared to the first). Individuals were 67% less likely to interrupt treatment with long-acting injectable than oral antipsychotics (aHR = 0.33; 95% CI = 0.27-0.41). Treatment for schizophrenia over the long term is often characterized by recurrent cycles of interruptions and reintroductions of antipsychotic medication, which is typically not recommended by management guidelines. Greater utilization of long-acting injectable formulations earlier in the course of illness may facilitate the continuity of antipsychotic treatment in schizophrenia.

[PMID: 33713580 PMCID: PMC8119821 DOI: 10.1002/brb3.2109] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2020] [Revised: 02/20/2021] [Accepted: 02/26/2021] [Indexed: 11/27/2022] Open
Abstract
INTRODUCTION The current study sought to compare the treatment continuation rates of asenapine and brexpiprazole while specifically investigating the factors influencing this index and the clinical efficacy of brexpiprazole. METHODS Retrospective study on patients with schizophrenia who were prescribed either asenapine (n = 73) or brexpiprazole (n = 136), as part of their routine medical care. RESULTS The treatment continuation rates for asenapine and brexpiprazole were 19.0% and 38.6% at 52 weeks, with that of brexpiprazole found to be significantly higher than that of asenapine (p = .002). Moreover, age was found to be a significant factor affecting the treatment continuation rate for brexpiprazole (p = .03). Additionally, patients with a longer continuation duration had significantly lower Clinical Global Impression-Severity of Illness (CGI-S) scale scores compared to those who discontinued early (p = .04). The continuation rate was also significantly higher for those who began using the drug as outpatients compared to those first administered the drug as inpatients (p = .04). Furthermore, disease duration, CGI-S scale, and continuation duration significantly affected the clinical efficacy of brexipiprazole (p < .05 for all). CONCLUSIONS The continuation rate for brexpiprazole increases as the age of the patient increases, as disease severity decreases, and if the patient first uses the drug as an outpatient. Shorter disease duration and longer drug administration may lead to improved clinical efficacy. These results suggest that brexpiprazole is an effective treatment option for maintenance therapy of schizophrenia.

Abstract
Practitioners lack guidance on how to support discontinuation of psychotropic medication. An understanding of what constitutes discontinuation success that encompasses the patients' perspective could advance knowledge in this clinically relevant area. Here, we report the development and validation of a scale to assess subjective discontinuation success. Participants who attempted discontinuing antidepressants and/or antipsychotics during the past 5 years (n = 396) completed a questionnaire on subjective discontinuation success (Discontinuation Success Scale, DSS) developed in consultation with people with lived experience of discontinuation. Construct validity was tested by exploratory and confirmatory factor analysis. Criterion validity was tested by assessing DSS-scores' associations with objective success (i.e., full cessation, reduced dose) in combination with scoring above a predefined criterion on the Well-Being Index. Factor analyses yielded a three-dimensional scale reflecting subjective discontinuation success, positive effects, and negative effects of discontinuation. A 24-item DSS demonstrated sufficient model fit for the participants discontinuing antidepressants or antipsychotics, respectively. Significant associations with objective success and well-being were found. Participants who had achieved full cessation and scored high on well-being reached the highest DSS scores. The DSS is a viable tool for future research aimed at identifying predictors of discontinuation success in order to inform recommendations related to discontinuation.

Key Variables for Effective eHealth Designs for Individuals With and Without Mental Health Disorders: 2^12-4 Fractional Factorial Experiment. J Med Internet Res 2021; 23:e23137. [PMID: 33759796 PMCID: PMC8262839 DOI: 10.2196/23137] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 12/07/2020] [Accepted: 12/18/2020] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND eHealth applications not only offer the potential to increase service convenience and responsiveness but also expand the ability to tailor services to improve relevance, engagement, and use. To achieve these goals, it is critical that the designs are intuitive. Limited research exists on designs that work for those with a severe mental illness (SMI), many of whom have difficulty traveling for treatments, reject or infrequently seek treatment, and tend to discontinue treatments for significant periods. OBJECTIVE This study aims to evaluate the influence of 12 design variables (eg, navigational depth, reading level, and use of navigational lists) on the usability of eHealth application websites for those with and without SMI. METHODS A 212-4 fractional factorial experiment was used to specify the designs of 256 eHealth websites. This approach systematically varied the 12 design variables. The final destination contents of all websites were identical, and only the designs of the navigational pages varied. The 12 design elements were manipulated systematically to allow the assessment of combinations of design elements rather than only one element at a time. Of the 256 websites, participants (n=222) sought the same information on 8 randomly selected websites. Mixed effect regressions, which accounted for the dependency of the 8 observations within participants, were used to test for main effects and interactions on the ability and time to find information. Classification and regression tree analyses were used to identify effects among the 12 variables on participants' abilities to locate information, for the sample overall and each of the 3 diagnostic groups of participants (schizophrenia spectrum disorder [SSD], other mental illnesses, and no mental illness). RESULTS The best and worst designs were identified for each of these 4 groups. The depth of a website's navigation, that is, the number of screens users needed to navigate to find the desired content, had the greatest influence on usability (ability to find information) and efficiency (time to find information). The worst performing designs for those with SSD had a 9% success rate, and the best had a 51% success rate: the navigational designs made a 42% difference in usability. For the group with other mental illnesses, the design made a 50% difference, and for those with no mental illness, a 55% difference was observed. The designs with the highest usability had several key design similarities, as did those with the poorest usability. CONCLUSIONS It is possible to identify evidence-based strategies for designing eHealth applications that result in significantly better performance. These improvements in design benefit all users. For those with SSD or other SMIs, there are designs that are highly effective. Both the best and worst designs have key similarities but vary in some characteristics.

Abstract
An important period in the care of patients with schizophrenia-spectrum disorders is when they transition from inpatient to outpatient services and are at increased risk for relapse and rehospitalization. Thus, we developed and examined the initial feasibility, acceptability, and clinical effects of an mHealth transitions of care intervention (Mobile After-Care Support; MACS) in an open trial. Ten adults with schizophrenia-spectrum disorders were recruited during their index psychiatric hospitalization and enrolled prior to discharge. Measures of feasibility, acceptability, and MACS targets were administered at baseline and a 1-month follow-up. Drawing on skills from Cognitive Behavioral Therapy for Psychosis (CBTp), MACS delivered brief assessments of clinically relevant variables, followed by just-in-time interventions for patients starting immediately post-discharge. Individuals completed about one session per day on average as expected. Overall, measures of MACS usability and satisfaction were positive. T-test analyses showed that dysfunctional coping strategies significantly decreased from baseline to 1-month follow-up. Results also revealed statistically significant reductions in psychiatric symptoms over 1-month follow-up. This study demonstrates the feasibility and acceptability of MACS, a new app-based intervention targeting transitions of care for patients with psychosis. The field is turning to the use of mobile technology as a means of augmenting service delivery and providing real-time assessment and intervention for patients at risk. MACS is a promising adjunctive intervention that warrants further testing in a randomized controlled trial.

Abstract
OBJECTIVE Ecological momentary assessment (EMA) via mobile devices offers a promising approach for collecting real-time data from psychiatric patients, potentially as an augment to traditional measurement-based care strategies. This study examined whether EMA had added value in collecting clinically important data from recently hospitalized adults with psychosis, relative to traditional assessments. METHOD In a sample of 24 adults with psychosis, EMA data regarding psychotic symptoms, affect, alcohol and drug use, functioning, quality of life, and social support were collected starting immediately posthospital discharge and extending for up to one month during their transition to outpatient care. EMA data were compared with traditional retrospective assessments of the same constructs, administered at a 1-month follow-up assessment. RESULTS Data from EMA and traditional retrospective assessments were correlated with each other in most cases. However, in some cases, participants were more likely to report drug use, medication nonadherence, and psychotic symptoms via EMA compared with traditional retrospective assessments. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Results suggest that the additional information obtained via frequent in-the-moment self-reports collected using smartphones can provide an expanded picture of individuals' symptomatic and functional experiences. Thus, monitoring patients' progress posthospitalization could be improved through the use of EMA. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Abstract
BACKGROUND Many patients with schizophrenia discontinue antipsychotic medication, frequently with adverse outcomes. Although different antipsychotic formulations are associated with different times to discontinuation, not much is known about discontinuation rates with oral-weekly formulations. Such a formulation of penfluridol is available in both the Netherlands and several other countries. OBJECTIVES We aimed to investigate the impact of antipsychotic formulations on time to discontinuation, especially the oral-weekly formulation. METHODS In a large, registry-based, retrospective cohort study from 1 January 2013 to 31 December 2016, we determined the time to medication discontinuation during the follow-up period with antipsychotic formulations, including oral-daily, oral-weekly, depot, or a combination of these. Patients with schizophrenia aged between 18 and 69 years were included and stratified according to the duration of recent antipsychotic use (taking the same formulation for ≤ 60 days or > 60 days before follow-up: short-term or long-term recent antipsychotic use). Medication discontinuation was defined as discontinuation of current antipsychotic formulation. RESULTS Overall, 8257 patients were included for analyses, with 80% of patients discontinuing antipsychotic medication. Time to discontinuation was longer in those with long-term recent antipsychotic use before the follow-up period and longest for oral-daily formulations. Patterns for discontinuation of oral-weekly and depot formulations were similar, regardless of the duration of recent antipsychotic use before follow-up. More prior discontinuations were associated with shorter time to discontinuation. CONCLUSIONS Time to discontinuation differed considerably between formulations. The duration of recent antipsychotic use was a strong predictor of time to discontinuation. While oral-daily formulations had the longest time to discontinuation in the long-term recent antipsychotic use group, discontinuation trends were similar for oral-weekly and depot formulations. An oral-weekly formulation, whose administration route is noninvasive, might therefore be considered an alternative to depot formulations.

Abstract
Extensive research has been carried out on the comparative effectiveness of antipsychotic medications. Most studies, however, have been performed in Western countries. The purpose of this study was to compare the effectiveness, indicated by time to any-cause discontinuation, of antipsychotic drugs in a large number of patients with schizophrenia in South Korea. We identified 1458 patients with schizophrenia or schizophreniform disorder who were treated with antipsychotic medications using a clinical data warehouse at the Seoul National University Hospital between March 2005 and February 2014. Kaplan–Meier survival analyses were used to estimate the time to discontinuation of antipsychotic drugs. We compared the survival curves of different antipsychotics using log-rank tests. Overall, the median time to discontinuation for any cause was 133 days (95% CI, 126–147). The longest time to discontinuation was observed for clozapine, followed by aripiprazole, paliperidone, olanzapine, amisulpride, risperidone, quetiapine, ziprasidone, and haloperidol. Specifically, clozapine was significantly different from all other antipsychotic drugs (all p < 0.001). Aripiprazole also had a significantly longer time to discontinuation than amisulpride (p = 0.001), risperidone (p < 0.001), quetiapine (p < 0.001), ziprasidone (p < 0.001), and haloperidol (p < 0.001). In Asian patients with schizophrenia, clozapine was the most effective antipsychotic in terms of time to discontinuation, followed by aripiprazole. This study extends the findings of previous effectiveness studies from Western populations and suggests the need to develop guidelines for the pharmacotherapy of schizophrenia tailored to Asian individuals.

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
Schizophrenia is a progressive disorder characterized by multiple psychotic relapses. After every relapse, patients may not fully recover, and this may lead to a progressive loss of functionality. Pharmacological treatment represents a key factor to minimize the biological, psychological and psychosocial impact of the disorder. The number of relapses and the duration of psychotic episodes induce a potential neuronal damage and subsequently, neurodegenerative processes. Thus, a comparative study was performed, including forty healthy controls and forty-two SZ patients divided into first-episode psychosis (FEP) and chronic SZ (CSZ) subgroups, where the CSZ sub group was subdivided by antipsychotic treatment. In order to measure the potential neuronal damage, plasma levels of β-III tubulin, neurofilament light chain (Nf-L), and glial fibrillary acidic protein (GFAP) were performed. The results revealed that the levels of these proteins were increased in the SZ group compared to the control group (P < 0.05). Moreover, multiple comparison analysis showed highly significant levels of β-III tubulin (P = 0.0002), Nf-L (P = 0.0403) and GFAP (P < 0.015) in the subgroup of CSZ clozapine-treated. In conclusion, β-III tubulin, Nf-L and GFAP proteins may be potential biomarkers of neurodegeneration and progression in SZ.

Health and work disability outcomes in parents of patients with schizophrenia associated with antipsychotic exposure by the offspring. Sci Rep 2020; 10:1219. [PMID: 31988392 PMCID: PMC6985214 DOI: 10.1038/s41598-020-58078-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Accepted: 01/10/2020] [Indexed: 11/24/2022] Open
Abstract
This study aimed to identify if antipsychotic exposure in offspring is associated with psychiatric and non-psychiatric healthcare service use and work disability of their parents. This Swedish population-based cohort study was based on data comprising 10,883 individuals with schizophrenia, who had at least one identifiable parent in the nationwide registers, and their parents (N = 18,215). The register-based follow-up during 2006–2013 considered the level of antipsychotic exposure and persistence of use of the offspring, further categorized into first (FG) and second generation (SG) antipsychotics, and orals versus long-acting injections (LAIs). The main outcome measure was parental psychiatric healthcare service use, secondary outcomes were non-psychiatric healthcare use and long-term sickness absence. SG-LAI use was associated with a decreased risk (relative risks [RR] 0.81-0.85) of parental psychiatric healthcare use compared with not using SG-LAI, whereas oral antipsychotics were associated with an increased risk (RRs 1.10–1.29). Both FG- and SG-LAI use by the offspring were associated with a lower risk of long-term sickness absence (range of odds ratios 0.34–0.47) for the parents, compared with non-use of these drugs. The choice of antipsychotic treatment for the offspring may have an impact on work disability and healthcare service use of their parents.

Aripiprazole Long-Acting Injection During First Episode Schizophrenia-An Exploratory Analysis. Front Psychiatry 2019; 10:935.

Abstract
Background: Long-acting injectable (LAI) aripiprazole was found to be efficacious in schizophrenia. In common clinical practice, the use of LAIs is often restricted to chronic patients with frequent relapses and poor adherence. Recently, some investigators advanced the idea of early LAI use also in young people with schizophrenia at their first psychotic episode (FEP). Objective: Our study aimed to assess the effect of LAI aripiprazole once monthly (AOM) in the treatment of FEP in patients aged 18-26 years. Methods: We included 50 patients with DSM-5 schizophrenia as assessed with SCID, and used the Clinical Global Impressions Scale-Severity of Illness (CGI-S) and the Positive and Negative Syndrome Scale (PANSS) to assess symptom severity and the World Health Organization Quality of Life (WHOQOL), the Short Form Health Survey (SF-36) and the Personal and Social Performance Scale (PSP) to assess quality of life (QoL) and global health perception at baseline and 3, 6, 9, and 12 months after the first AOM injection. Results: AOM was associated with a progressive improvement, compared to baseline, of both positive (p < 0.001) and negative (p < 0.001) symptoms and in general psychopathology (p < 0.001) and decrease in global severity (p < 0.001). We also observed progressive improvement in QoL and social and personal functioning. Treatment adherence was 78% at study endpoint. Our results support that AOM may improve psychotic symptoms, QoL and social functioning in young FEP patients. Further studies should compare AOM to its oral formulation in the treatment of young patients with schizophrenia at the outset of their illness.

Abstract
BACKGROUND People with psychosis struggle with decisions about their use of antipsychotics. They often want to reduce the dose or stop, while facing uncertainty regarding the effects these decisions will have on their treatment and recovery. They may also fear raising this issue with clinicians. The purpose of this study was to develop and test a shared decision making (SDM) tool to support patients and clinicians in making decisions about antipsychotics. METHODS A diverse editorial research team developed an Encounter Decision Aid (EDA) for patients and clinicians to use as part of the psychiatric consultation. The EDA was tested using 24 semistructured interviews with participants representing six stakeholder groups: patients with first-episode psychosis, patients with long-term psychosis, family members, psychiatrists, mental health counselors, and administrators. We used inductive and deductive coding of interview transcripts to identify points to revise within three domains: general impression and purpose of the EDA; suggested changes to the content, wording, and appearance; and usability and potential contribution to the psychiatric consultation. RESULTS An EDA was developed in an iterative process that yielded evidence-based answers to five frequently asked questions about antipsychotic medications. Patients with long-term psychosis and mental health counselors suggested more changes and revisions than patients with first-episode psychosis and psychiatrists. Family members suggested more revisions to the answers about potential risks of stopping or adjusting antipsychotics than other respondents. CONCLUSIONS The EDA was perceived as potentially useful and feasible in psychiatric routine care, especially if presented during the consultation.

Abstract
Background A text messaging service (short message service [SMS]) has the potential to target large groups of people with long-term illnesses such as serious mental disorders, who may have difficulty with treatment adherence. Robust research on the impact of mobile technology interventions for these patients remains scarce. Objective The main objective of our study was to investigate the impact of individually tailored short text messages on the rate of psychiatric hospital readmissions, health care service use, and clinical outcomes. In addition, we analyzed treatment costs. Methods Between September 2011 and November 2012, we randomly assigned 1139 people to a tailored text message intervention (n=569) or usual care (n=570). Participants received semiautomated text messages for up to 12 months or usual care. The primary outcome, based on routinely collected health register data, was patient readmission into a psychiatric hospital during a 12-month follow-up period. Secondary outcomes were related to other service use, coercion, medication, adverse events, satisfaction, social functioning, quality of life, and economic factors (cost analysis). Results There was 98.24% (1119/1139) follow-up at 12 months. Tailored mobile telephone text messages did not reduce the rate of hospital admissions (242/563, 43.0% of the SMS group vs 216/556, 38.8% of the control group; relative risk 1.11; 95% CI 0.92-1.33; P=.28), time between hospitalizations (mean difference 7.0 days 95% CI –8.0 to 24.0; P=.37), time spent in a psychiatric hospital during the year (mean difference 2.0 days 95% CI –2.0 to 7.0; P=.35), or other service outcomes. People who received text messages were less disabled, based on Global Assessment Scale scores at the time of their readmission, than those who did not receive text messages (odds ratio 0.68; 95% CI 0.47-0.97; P=.04). The costs of treatment were higher for people in the SMS group than in the control group (mean €10,103 vs €9210, respectively, P<.001). Conclusions High-grade routinely collected data can provide clear outcomes for pragmatic randomized trials. SMS messaging tailored with the input of each individual patient did not decrease the rate of psychiatric hospital visits after the 12 months of follow-up. Although there may have been other, more subtle effects, the results of these were not evident in outcomes of agreed importance to clinicians, policymakers, and patients and their families.

Abstract
We conducted this study to explore personal accounts of making choices about taking medication prescribed for the treatment of psychosis (neuroleptics). There are costs and benefits associated with continuing and discontinuing neuroleptics. Service users frequently discontinue neuroleptics; therefore, we specifically considered these decisions. We used a grounded theory approach to analyze transcripts from interviews with 12 participants. We present a preliminary grounded theory of the processes involved in making choices about neuroleptic medication. We identified three tasks as important in mediating participants' choices: (a) forming a personal theory of the need for, and acceptability of taking, neuroleptic medication; (b) negotiating the challenges of forming alliances with others; and (c) weaving a safety net to safeguard well-being. Progress in the tasks reflected a developmental trajectory of becoming an expert over time and was influenced by systemic factors. Our findings highlight the importance of developing resources for staff to facilitate service user choice.

Abstract
PURPOSE A retrospective study was conducted to evaluate the time to discontinuation (TTD) of the first- (FGAs) and second-generation antipsychotics (SGAs). METHODS In total, 918 treatment episodes of patients with schizophrenia, initiated on one of the investigated drugs on an outpatient basis during 2004-2006, were entered into the study. The primary outcome was the duration of the investigated treatment episode. Discontinuation was defined when either patients were admitted or the investigated drug had been stopped for more than 28 days. We used the Cox proportional hazard model to compare hazards of discontinuations among 8 SGAs versus 2 FGAs (haloperidol and sulpiride). The follow-up period was up to 18 months. RESULTS During the follow-up period, clozapine had the highest rate of continuous treatment in the primary analysis: clozapine, 40.6%; olanzapine, 23.4%; aripiprazole, 22.9%; amisulpride, 21.9%; zotepine, 21.3%; sulpiride, 17.0%; risperidone, 12.8%; quetiapine, 12.5%; haloperidol, 10.6%; and ziprasidone, 10.4%. Compared with haloperidol, 5 SGAs had significantly longer TTD (adjusted hazard ratios and 95% confidence intervals): clozapine (0.403, 0.267-0.607), olanzapine (0.611, 0.439-0.849), aripiprazole (0.570, 0.407-0.795), amisulpride (0.680, 0.487-0.947), and zotepine (0.687, 0.497-0.948), but only clozapine had significantly longer TTD compared with sulpiride (0.519, 0.342-0.786). The sensitivity analysis showed similar results. IMPLICATIONS/CONCLUSIONS The current findings suggested that SGAs or FGAs are not homogeneous groups. Clozapine has the highest rate of continuous treatment among SGAs, and haloperidol is not the representative drug for all FGAs. Furthermore, antipsychotics dropout rate is high in naturalistic situation. A good service model needs to be constructed to enhance antipsychotic treatment adherence of people with schizophrenia.

Abstract
OBJECTIVE The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting. METHODS We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study. We investigated the discontinuation rate and the mean time to discontinuation among six antidepressants groups. RESULTS Mean and median overall discontinuation times were 13.8 and 12 weeks, respectively. Sertraline and escitalopram had longer discontinuation times than that of fluoxetine, and patients who used sertraline discontinued use significantly later than those taking mirtazapine. No differences in discontinuation rate were observed after 24 weeks among these antidepressants. About 73% of patients discontinued antidepressant treatment after 24 weeks. CONCLUSION Sertraline and escitalopram tended to have longer mean times to discontinuation, although no difference in discontinuation rate was detected between antidepressants after 24 weeks. About three-quarters of patients discontinued antidepressant maintenance therapy after 24 weeks.

Abstract
Introduction: The objective of this research is to explore and share the medication experience of those with a mental illness in order to gain understanding of the patient's medication perceptions as well as the impact of medication upon patients' lives. Methods: Patients with a mental disorder were given cameras and asked to capture the experience of “living with my medication.” Using Photovoice methodology, participants reflected on their photos individually and in focus groups. Conceptual themes were drawn from the data. Results: Five participants captured an average of 14 photos each. Self-efficacy with mental illness, mental and physical health connections, and education were the 3 most prominent themes. Aspects of medications were interwoven within these themes but were not the primary focus of the participants. Discussion: Medication experiences of patients with mental illness may encompass much more than the medications themselves.

Abstract
Background Offering a modest financial incentive to people with psychosis can promote adherence to depot antipsychotic medication, but the cost-effectiveness of this approach has not been examined. Methods Economic evaluation within a pragmatic cluster-randomised controlled trial. 141 patients under the care of 73 teams (clusters) were randomised to intervention or control; 138 patients with diagnoses of schizophrenia, schizo-affective disorder or bipolar disorder participated. Intervention participants received £15 per depot injection over 12 months, additional to usual acute, mental and community primary health services. The control group received usual health services. Main outcome measures: incremental cost per 20% increase in adherence to depot antipsychotic medication; incremental cost of ‘good’ adherence (defined as taking at least 95% of the prescribed number of depot medications over the intervention period). Findings Economic and outcome data for baseline and 12-month follow-up were available for 117 participants. The adjusted difference in adherence between groups was 12.2% (73.4% control vs. 85.6% intervention); the adjusted costs difference was £598 (95% CI -£4 533, £5 730). The extra cost per patient to increase adherence to depot medications by 20% was £982 (95% CI -£8 020, £14 000). The extra cost per patient of achieving 'good' adherence was £2 950 (CI -£19 400, £27 800). Probability of cost-effectiveness exceeded 97.5% at willingness-to-pay values of £14 000 for a 20% increase in adherence and £27 800 for good adherence. Interpretation Offering a modest financial incentive to people with psychosis is cost-effective in promoting adherence to depot antipsychotic medication. Direct healthcare costs (including costs of the financial incentive) are unlikely to be increased by this intervention. Trial Registration ISRCTN.com 77769281

Abstract
BACKGROUND The challenges of comparative effectiveness to support health technology assessment (HTA) agencies are important considerations in the choices of antipsychotic medications for the treatment of schizophrenia. OBJECTIVES Our aim was to assess the study methods used and outcomes reported in the published literature to address the question of comparative effectiveness of newer antipsychotic agents and the adequacy and availability of evidence to support HTA agencies. DATA SOURCE A systematic search of the PubMed database from 1 January 2009 to 30 September 2013 was conducted to identify studies evaluating new atypical antipsychotics reporting on comparative effectiveness. STUDY SELECTION The systematic review comprised of studies on schizophrenia patients where at least two drugs were being compared and at least one treatment group received one of the following second-generation antipsychotics: risperidone, olanzapine, aripiprazole, paliperidone, asenapine, iloperidone, lurasidone, and quetiapine. The included studies were also required to have an efficacy, safety or economic outcome, such as Positive and Negative Syndrome Scale (PANSS) score, weight gain, resource utilization, or costs. STUDY APPRAISAL AND SYNTHESIS METHODS Two reviewers (BW and GK) independently applied the inclusion criteria. Disagreements between reviewers were resolved by consensus, referring to the original sources. Information on the methodology and outcomes was collected for each included study. This included study description, head-to-head drug comparison, patient population, study methodology, statistical methods, reported outcomes, study support, and journal type. RESULTS A total of 198 studies were identified from electronic search methods. The largest category of studies was randomized controlled trials [RCTs] (N = 73; 36.9%), which were largely directed at the regulatory endpoint. Fewer studies were undertaken for HTA-purposes cohort studies (N = 53; 26.8%), meta-analyses (N = 32; 16.2%), economic studies (N = 14; 7.1%), and cross-sectional studies (N = 13; 6.6%). Direct head-to-head comparisons preferred by HTA were dominated by the comparison involving olanzapine and risperidone, representing 149 (75.3%) and 119 (60.1%) studies, respectively. RCTs, which are the primary study type for regulatory submissions, showed a lack of bias. Studies aimed at HTA were not as well performed. Cohort studies suffered from bias in the selection of comparison groups, lack of control for confounders, and differential dropout rates. As a group, cross-sectional studies scored poorly for bias, with a primary failure to identify a representative sample. Economic studies showed highly variable bias, with bias in the representation of effectiveness data, model assumptions without validation, and lack of sensitivity analyses. LIMITATIONS One limitation of this systematic review is that it only included studies from 2009 to 2013, potentially excluding some earlier comparator studies, particularly those involving first-generation antipsychotics. CONCLUSIONS This review of comparative effectiveness studies of second-generation antipsychotic agents for schizophrenic patients revealed a wide range of study types, study methodologies, and outcomes. For traditional efficacy outcomes and select safety outcomes, there is strong evidence from many well-conducted studies; however, there are fewer studies of types preferred by HTA with limited head-to-head comparisons and a higher risk of bias in the execution of these studies.

Abstract
OBJECTIVE Failure to adhere to treatment with antipsychotic medication is the most common cause of relapse among patients with schizophrenia. A novel multifamily group (MFG) intervention, informed by the Theory of Planned Behavior (TPB), demonstrated efficacy in increasing medication adherence and decreasing rehospitalizations in schizophrenia patients. This report explores the hypothesis that the improved outcomes obtained through the MFG approach were mediated by changes in the patients' attitudes toward medications, subjective norms-social influences, and perceived behavioral control of resources. METHOD Data from a recently completed, randomized controlled trial of MFG was used to test the hypothesis that the improvement in adherence was mediated by the 3 TPB factors. Subjects were 174 Mexican American adults with schizophrenia-spectrum disorder who had participated in a study of MFG focused on improving medication adherence. Assessments occurred at baseline and at 4, 8, 12, 18, and 24 months. RESULTS Path analysis revealed that the increased adherence associated with MFG was mediated by improvements in subjective norms but not attitudes toward medications nor perceived behavioral control. CONCLUSION An MFG treatment specifically tailored to increase medication adherence among Mexican Americans with schizophrenia achieved its benefits by leveraging social influences through teaching family members how to support medication adherence in their ill relatives.

Abstract
Severe mental illnesses, including schizophrenia and other psychotic-spectrum disorders, are a major cause of disability worldwide. Although efficacious pharmacological and psychosocial interventions have been developed for treating patients with schizophrenia, relapse rates are high and long-term recovery remains elusive for many individuals. Furthermore, little is still known about the underlying mechanisms of these illnesses. Thus, there is an urgent need to better understand the contextual factors that contribute to psychosis so that they can be better targeted in future interventions. Ecological Momentary Assessment (EMA) is a dynamic procedure that permits the measurement of variables in natural settings in real-time through the use of brief assessments delivered via mobile electronic devices (i.e., smart phones). One advantage of EMA is that it is less subject to retrospective memory biases and highly sensitive to fluctuating environmental factors. In the current article, we describe the research-to-date using EMA to better understand fluctuating symptoms and functioning in patients with schizophrenia and other psychotic disorders and potential applications to treatment. In addition, we describe a novel EMA protocol that we have been employing to study the outcomes of patients with schizophrenia following a hospital discharge. We also report the lessons we have learned thus far using EMA methods in this challenging clinical population.

Abstract
AIM To determine optimal sampling strategies to allow the calculation of clinical pharmacokinetic parameters for selected antipsychotic medicines using a pharmacometric approach. METHODS This study utilized previous population pharmacokinetic parameters of the antipsychotic medicines aripiprazole, clozapine, olanzapine, perphenazine, quetiapine, risperidone (including 9-OH risperidone) and ziprasidone. d-optimality was utilized to identify time points which accurately predicted the pharmacokinetic parameters (and expected error) of each drug at steady-state. A standard two stage population approach (STS) with MAP-Bayesian estimation was used to compare area under the concentration-time curves (AUC) generated from sparse optimal time points and rich extensive data. Monte Carlo Simulation (MCS) was used to simulate 1000 patients with population variability in pharmacokinetic parameters. Forward stepwise regression analysis was used to determine the most predictive time points of the AUC for each drug at steady-state. RESULTS Three optimal sampling times were identified for each antipsychotic medicine. For aripiprazole, clozapine, olanzapine, perphenazine, risperidone, 9-OH risperidone, quetiapine and ziprasidone the CV% of the apparent clearance using optimal sampling strategies were 19.5, 8.6, 9.5, 13.5, 12.9, 10.0, 16.0 and 10.7, respectively. Using the MCS and linear regression approach to predict AUC, the recommended sampling windows were 16.5-17.5 h, 10-11 h, 23-24 h, 19-20 h, 16.5-17.5 h, 22.5-23.5 h, 5-6 h and 5.5-6.5 h, respectively. CONCLUSION This analysis provides important sampling information for future population pharmacokinetic studies and clinical studies investigating the pharmacokinetics of antipsychotic medicines.

Abstract
BACKGROUND A number of serious cardiovascular safety concerns related to the use of atypical antipsychotics, compared with no use, have emerged, but nearly all reports are from studies of older patients. We aimed to compare the risk of cardiovascular events between the three most commonly used atypical antipsychotics in young and middle-aged adults. METHODS We conducted a nationwide register-based cohort study in Denmark, 1997-2011, including adults aged 18-64 years, who started treatment with oral or intramuscular olanzapine (n = 15,774), oral quetiapine (n = 18,717), and oral or intramuscular risperidone (n = 14,134). The primary outcome was any major cardiovascular event (composite of cardiovascular mortality, acute coronary syndrome, or ischemic stroke) within 1 year following treatment initiation. Cox regression was used to estimate hazard ratios (HRs) while on current antipsychotic monotherapy in the outpatient setting, adjusting for an outcome-specific disease risk score. RESULTS The crude rate of any major cardiovascular event was 5.3 per 1,000 person-years among olanzapine users, 3.4 in quetiapine users, and 5.2 in risperidone users. Compared with risperidone, the risk of any major cardiovascular event was not significantly different in olanzapine users (HR 0.90, 95 % confidence interval [CI] 0.53-1.52) and quetiapine users (HR 0.79, 95 % CI 0.45-1.39). The absolute risk difference per 1,000 person-years on treatment was -0.5 (95 % CI -2.4 to 2.7) events for olanzapine and -1.1 (95 % CI -2.9 to 2.0) events for quetiapine. CONCLUSIONS Among young and middle-aged outpatients, the risk of acute major cardiovascular events was similar with use of olanzapine, quetiapine, and risperidone. Although moderate relative differences cannot be ruled out, any differences are small in absolute terms.

Abstract
BACKGROUND Compliance is often partial with oral antipsychotics and underestimated for patients with serious mental illness. Despite their demonstrated advantages in terms of relapse prevention, depot formulations are still poorly used in routine. As part of a process to improve the quality of care, French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) Task Force elaborated a Formal Consensus for the prescription of depot antipsychotics in clinical practice. METHODS The Task Force recommends as first-line choice, the use of long-acting injectable (LAI) second-generation antipsychotics in patients with schizophrenia, schizoaffective disorder and delusional disorder. They can be considered as a second-line option as a monotherapy to prevent manic recurrence or in combination with mood stabilizer to prevent depressive recurrence in the maintenance treatment of bipolar disorder. LAI second-generation antipsychotics can also be used after a first episode of schizophrenia. Depot neuroleptics are not recommended during the early course of schizophrenia and are not appropriate in bipolar disorder. They are considered as a second-line option for maintenance treatment in schizophrenia. RESULTS LAI formulations should be systematically proposed to any patients for whom maintenance antipsychotic treatment is indicated. LAI antipsychotics can be used preferentially for non-compliant patients with frequent relapses or aggressive behaviors. CONCLUSION A specific information concerning the advantages and inconveniences of the LAI formulations, in the framework of shared-decision making must be delivered to each patient. Recommendations for switching from one oral/LAI form to another LAI and for using LAI antipsychotics in specific populations (pregnant women, elderly patients, subjects in a precarious situation, and subjects having to be treated in a prison establishment) are also proposed.

Abstract
BACKGROUND Long-acting injectable (LAI) formulations are not widely used in routine practice even though they offer advantages in terms of relapse prevention. As part of a process to improve the quality of care, the French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) elaborated guidelines for the use and management of antipsychotic depots in clinical practice. METHODS Based on a literature review, a written survey was prepared that asked about 539 options in 32 specific clinical situations concerning 3 fields: target-population, prescription and use, and specific populations. We contacted 53 national experts, 42 of whom (79%) completed the survey. The options were scored using a 9-point scale derived from the Rand Corporation and the University of California in the USA. According to the answers, a categorical rank (first-line/preferred choice, second-line/alternate choice, third-line/usually inappropriate) was assigned to each option. The first-line option was defined as a strategy rated as 7-9 (extremely appropriate) by at least 50% of the experts. The following results summarize the key recommendations from the guidelines after data analysis and interpretation of the results of the survey by the scientific committee. RESULTS LAI antipsychotics are indicated in patients with schizophrenia, schizoaffective disorder, delusional disorder and bipolar disorder. LAI second-generation antipsychotics are recommended as maintenance treatment after the first episode of schizophrenia. LAI first-generation antipsychotics are not recommended in the early course of schizophrenia and are not usually appropriate in bipolar disorder. LAI antipsychotics have long been viewed as a treatment that should only be used for a small subgroup of patients with non-compliance, frequent relapses or who pose a risk to others. The panel considers that LAI antipsychotics should be considered and systematically proposed to any patients for whom maintenance antipsychotic treatment is indicated. Recommendations for medication management when switching oral antipsychotics to LAI antipsychotics are proposed. Recommendations are also given for the use of LAI in specific populations. CONCLUSION In an evidence-based clinical approach, psychiatrists, through shared decision-making, should be systematically offering to most patients that require long-term antipsychotic treatment an LAI antipsychotic as a first-line treatment.

Abstract
This article is an update of the algorithm for schizophrenia from the Psychopharmacology Algorithm Project at the Harvard South Shore Program. A literature review was conducted focusing on new data since the last published version (1999-2001). The first-line treatment recommendation for new-onset schizophrenia is with amisulpride, aripiprazole, risperidone, or ziprasidone for four to six weeks. In some settings the trial could be shorter, considering that evidence of clear improvement with antipsychotics usually occurs within the first two weeks. If the trial of the first antipsychotic cannot be completed due to intolerance, try another until one of the four is tolerated and given an adequate trial. There should be evidence of bioavailability. If the response to this adequate trial is unsatisfactory, try a second monotherapy. If the response to this second adequate trial is also unsatisfactory, and if at least one of the first two trials was with risperidone, olanzapine, or a first-generation (typical) antipsychotic, then clozapine is recommended for the third trial. If neither trial was with any these three options, a third trial prior to clozapine should occur, using one of those three. If the response to monotherapy with clozapine (with dose adjusted by using plasma levels) is unsatisfactory, consider adding risperidone, lamotrigine, or ECT. Beyond that point, there is little solid evidence to support further psychopharmacological treatment choices, though we do review possible options.

Abstract
PURPOSE The aim of this study was to measure persistence with pharmacological treatment in the specialist mental healthcare of patients with schizophrenia, bipolar disorder, and unipolar depression in Lombardy, a region of 10 million inhabitants located in the northernmost part of Italy. METHODS The data concerning psychiatric care used in this study were retrieved from the regional Psychiatric Information System, while information on drug treatment was retrieved from the regional administrative database. Time to lack of persistence with initial pharmacological treatment was the outcome measure. RESULTS A total of 11,797 patients, followed in the specialist mental healthcare system, started a new pharmacological treatment for depression, schizophrenia, or bipolar disorder during 2007. Overall, 8,500 patients (72.1%) discontinued treatment during the 12 month follow-up, with a median duration of 101 days. Very similar discontinuation rates were observed in patients with unipolar depression, schizophrenia, and bipolar disorder. In the multivariate analysis, operational definitions of continuity and intensity of care were the most robust determinants of persistence with drug treatment in each of the three cohorts of psychiatric diagnoses. CONCLUSIONS High rates of treatment discontinuation were found in a population of patients with severe mental disorders followed in the specialist mental healthcare system of an Italian region, with no differences among patients with unipolar major depression, schizophrenia, and bipolar disorder. These findings corroborate the notion that the problem of treatment discontinuation in psychiatric disorders is a factor related to the capacity of the mental health system to assure and maintain continuity and intensity of care.

Abstract
BACKGROUND Little is known about the comparative effectiveness of atypical antipsychotics in long-acting injection formulation. Due to the absence of head-to-head studies comparing olanzapine long-acting injection and risperidone long-acting injection, this study was intended to make exploratory, indirect, cross-study comparisons between the long-acting formulations of these two atypical antipsychotics in their effectiveness in treating patients with schizophrenia. METHODS Indirect, cross-study comparisons between olanzapine long-acting injection and risperidone long-acting injection used 12-month treatment-completion rates, because discontinuation of an antipsychotic for any cause is a recognized proxy measure of the medication's effectiveness in treating schizophrenia. Following a systematic review of the literature, two indirect comparisons were conducted using open-label, single-cohort studies in which subjects were stabilized on an antipsychotic medication before depot initiation. The first analysis compared olanzapine long-acting injection (one study) with pooled data from nine identified risperidone long-acting injection studies. The second analysis was a "sensitivity analysis," using only the most similar studies, one for olanzapine long-acting injection and one for risperidone long-acting injection, which shared near-identical study designs and involved study cohorts with near-identical patient characteristics. Pearson Chi-square tests assessed group differences on treatment-completion rates. RESULTS Comparison of olanzapine long-acting injection data (931 patients) with the pooled data from the nine risperidone long-acting injection studies (3950 patients) provided almost identical 12-month treatment-completion rates (72.7% versus 72.4%; P = 0.87). When the two most similar studies were compared, the 12-month completion rate for olanzapine long-acting injection was significantly higher than for risperidone long-acting injection (81.3% versus 47.0%; P < 0.001). However, any conclusions drawn from this comparison may be limited by differences in the studies' geographic catchment areas. CONCLUSION Using treatment-completion rates as a proxy measure of medication effectiveness, olanzapine long-acting injection did not differ significantly from risperidone long-acting injection when including all eligible studies. However, the findings of this exploratory analysis should be interpreted with caution, considering the methodological limitations of these indirect, cross-study comparisons.

OBJECTIVE: Treatment of schizophrenia in patients with comorbid substance use (alcohol/illicit drug use, abuse or dependence) presents challenges for public health systems. Substance use in people with schizophrenia is up to four times greater than the general population and is associated with medication nonadherence and poor outcomes. Therefore, continuous antipsychotic treatment in this population may pose more of a challenge than for those with schizophrenia alone. Many clinical trials and treatment recommendations in schizophrenia do not take into consideration substance use as people with comorbid substance use have typically been excluded from most antipsychotic trials. Nonetheless, antipsychotic treatment appears to be as efficacious in this population, although treatment discontinuation remains high. The objective of this review was to highlight the importance and utility of considering long-acting injectable antipsychotics for patients with schizophrenia and comorbid substance use. METHODS: We did a literature search using PubMed with key words schizophrenia and substance use/abuse/dependence, nonadherence, antipsychotics, long acting injectables, relapse, and psychosocial interventions. We limited our search to human studies published in English and 4,971 articles were identified. We focused on clinical trials, case reports, case series, reviews and meta-analyses resulting in 125 articles from 1975-2011. RESULTS: Our review suggests the potential role of long-acting injectables for people with comorbid substance use and schizophrenia in leading to improvements in psychopathology, relapse prevention, fewer rehospitalizations, and better outcomes. CONCLUSIONS: While more research is needed, long-acting antipsychotics should be considered an important option in the management of people with schizophrenia and comorbid substance use.

Role of long-acting injectable second-generation antipsychotics in the treatment of first-episode schizophrenia: a clinical perspective. SCHIZOPHRENIA RESEARCH AND TREATMENT 2012; 2012:764769. [PMID: 22966444 PMCID: PMC3420571 DOI: 10.1155/2012/764769] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/24/2011] [Revised: 02/15/2012] [Accepted: 02/15/2012] [Indexed: 11/18/2022]
Abstract
Approximately 80% of patients with the first-episode schizophrenia reach symptomatic remission after antipsychotic therapy. However, within two years most of them relapse, mainly due to low levels of insight into the illness and nonadherence to their oral medication. Therefore, although the formal data available is limited, many experts recommend prescribing long-acting injectable second-generation antipsychotics (mostly risperidone or alternatively paliperidone) in the early stages of schizophrenia, particularly in patients who have benefited from the original oral molecule in the past and agree to receive long-term injectable treatment. Early application of long-acting injectable second-generation antipsychotics can significantly reduce the risk of relapse in the future and thus improve not only the social and working potential of patients with schizophrenia but also their quality of life.

Abstract
PURPOSE Treatment continuation is considered an important measure of antipsychotic effectiveness in schizophrenia, reflecting the medication's efficacy, safety, and tolerability from both patients' and clinicians' perspectives. This study identified characteristics of patients with schizophrenia who continue olanzapine therapy for a 1-year period in Japan. METHODS In a large (N = 1850), prospective, observational study, Japanese patients with schizophrenia who initiated treatment with olanzapine were followed for 1 year. Baseline characteristics were compared using t-tests and chi-square tests. Stepwise logistic regression was used to identify independent baseline predictors of treatment continuation. RESULTS Most patients (68.2%) continued with olanzapine therapy for the full 1-year study period, with an average duration of 265.5 ± 119.4 days. At baseline, patients who continued were significantly more likely to be male, older, and inpatients; have longer illness duration, higher negative and cognitive symptoms, better health-related quality of life, and prior anticholinergic use. Continuers were significantly less likely to engage in social activities, live independently, work for pay, or have prior antidepressant use. Continuers showed significantly greater early (3-month) improvement in global symptom severity. Logistic regression found that continuation was significantly predicted by longer illness duration, lower positive symptoms, higher negative symptoms, and better health-related quality of life. CONCLUSIONS In this large naturalistic study in Japan, most patients with schizophrenia stayed on olanzapine therapy for the full 1-year study period. Treatment completion with olanzapine was independently predicted by longer illness duration, lower positive symptoms, higher negative symptoms, and better health-related quality of life.

Changes in schizophrenia-related hospitalization and ER use among patients receiving paliperidone palmitate: results from a clinical trial with a 52-week open-label extension (OLE).

Abstract
BACKGROUND Schizophrenia affects ∼1.1% of the United States population, resulting in substantial direct, indirect and societal costs. OBJECTIVE To evaluate hospitalization rates associated with use of paliperidone palmitate (PP). METHODS Data were from a variable-duration double-blind (DB), randomized, relapse-prevention comparison (NCT00111189) of PP vs. placebo (Pbo), followed by a 1-year open-label extension (OLE). Between-phase change in schizophrenia-related hospitalizations was evaluated using data from an investigator-completed questionnaire. Change in hospitalizations using patients before enrollment who participated in the OLE phase was also analyzed. Poisson regression was used to evaluate changes in incidence density within exposure category and by schizophrenia duration. RESULTS A total of 160 patients in the PP-PP group and 153 in the Pbo-PP group from the DB to the OLE phase were included. Mean age (standard deviation [SD]), gender, and duration of schizophrenia were similar at the start of the DB phase (Pbo: 38.5 years [10.6], 51.0% male, 68.0% ≥5 years' duration; PP: 37.3 years [11.4] (p = 0.342); 51.9% male (p = 0.874); 70.0% ≥5 years' duration (p = 0.698), respectively. From the DB to the end of the OLE phase, the number of hospitalizations per person-year for patients treated during the DB phase with Pbo significantly declined from 0.27 to 0.06 (78% reduction; p = 0.005). A statistically nonsignificant difference was observed for PP patients treated during the DB phase with PP (0.11-0.04; 63.6% reduction; p = 0.076), compared with the OLE phase. Change from before enrollment to the end of the OLE phase (n = 381) produced similar results (0.35-0.04; 88.6% reduction; p < 0.001). Patients who enroll in a clinical trial may be different from the general population and this may affect the generalizability of results. CONCLUSION From the double-blind to the open-label phase and from prior to the trial until the end of the open-label phase, hospitalizations significantly decreased for patients with schizophrenia treated with PP.
