Abstract
Antipsychotic polypharmacy (APP) has become prevalent over the years, but several concerns have been raised over APP. Accumulating evidence suggests that aripiprazole long-acting injectable (LAI) may reduce the rate of APP, but the association remains speculative. This retrospective observational study included 127 patients with psychosis and observed them for 1.8 ± 1.3 years, up to 4 years. Prescription data of antipsychotics (APs), mood stabilisers, benzodiazepines, and anti-extrapyramidal side effect medications were obtained at baseline and the last observation. Daily chlorpromazine equivalent (CPZ) dose of APs decreased from 124.40 ± 235.35 mg to 77.95 ± 210.36 mg ( P = 0.027). The daily dose of anticholinergics and beta-blockers also significantly decreased after introducing aripiprazole LAI. Among the patients having APP, the number of concurrent APs along with daily CPZ dose of APs decreased after initiation of aripiprazole LAI from 1.28 ± 0.62 to 0.85 ± 0.73 ( P < 0.001) and 298.33 ± 308.70 mg to 155.43 ± 280.53 mg ( P = 0.004), respectively. Treatment with aripiprazole LAI for up to 4 years in patients with psychosis was associated with a reduced number of prescribed APs in patients having an APP and a reduced dose of APs and concurrent psychotropic medications.

Abstract
It is important to examine the psychotropic prescription practices in schizophrenia, as it can inform regarding changing treatment choices and related patient profiles. No recent reviews have evaluated the global neuropsychopharmacological prescription patterns in adults with schizophrenia. A systematic search of the literature published from 2002 to 2023 found 88 empirical papers pertinent to the utilization of psychotropic agents. Globally, there were wide inter-country and inter-regional variations in the prescription of psychotropic agents. Overall, over time there was an absolute increase in the prescription rate of second-generation antipsychotics (up to 50%), mood stabilizers (up to 15%), and antidepressants (up to 17%), with an observed absolute decrease in the rate of antipsychotic polypharmacy (up to 15%), use of high dose antipsychotic (up to 12% in Asia), clozapine (up to 9%) and antipsychotic long-acting injectables (up to 10%). Prescription patterns were mainly associated with specific socio-demographic (such as age), illness (such as illness duration), and treatment factors (such as adherence). Further work, including more evidence in adjunctive neuropsychopharmacological treatments, pharmaco-economic considerations, and examination of cohorts in prospective studies, can proffer insights into changing prescription trends relevant to different treatment settings and predictors of such trends for enhancement of clinical management in schizophrenia.

Abstract
BACKGROUND Polypharmacy of additional psychotropics alongside the main treatment drug (antipsychotics in schizophrenia and antidepressants in major depressive disorder) is common in Japan. Our goal is to align psychotropic prescription in Japan with international standards, while reducing the differences between facilities. To achieve this goal, we aimed to compare prescriptions at the time of hospital admission and discharge. METHODS Data on prescriptions at admission and discharge from 2016 to 2020 were collected. We divided the patients into four groups: (1) mono_mono group, monotherapy of the main drug at admission and discharge; (2) mono_poly group, monotherapy at admission and polypharmacy at discharge; (3) poly_poly group, polypharmacy at admission and discharge; and (4) poly_mono group, polypharmacy at admission and monotherapy at discharge. We compared the changes in dosage and number of psychotropics among the four groups. RESULTS For both schizophrenia and major depressive disorder, the patients who received monotherapy with the main drug at admission were likely to receive main drug monotherapy at discharge and vice versa. For schizophrenia, the polypharmacy was prescribed more often in the mono_poly group than that in the mono_mono group. The prescription was not changed at all for more than 10% of the patients. CONCLUSIONS It is critical to avoid a polypharmacy regimen to ensure that guideline-compliant treatment is provided. We expect higher rates of monotherapy with the main drug after the EGUIDE lectures. TRIAL REGISTRATION The study protocol was registered in the University Hospital Medical Information Network Registry (UMIN000022645).

Abstract
Antipsychotic polypharmacy (APP) in patients with schizophrenia spectrum disorders (SSDs) is usually not recommended, though it is very common in clinical practice. Both APP and SSDs have been linked to worse health outcomes and decreased levels of physical activity, which in turn is an important risk factor for cardiovascular diseases and premature mortality. This real-world, observational study aimed to investigate antipsychotic prescribing patterns and physical activity in residential patients and outpatients with SSDs. A total of 620 patients and 114 healthy controls were recruited in 37 centers across Italy. Each participant underwent a comprehensive sociodemographic and clinical evaluation. Physical activity was monitored for seven consecutive days through accelerometer-based biosensors. High rates of APP were found in all patients, with residential patients receiving more APP than outpatients, probably because of greater psychopathological severity. Physical activity was lower in patients compared to controls. However, patients on APP showed trends of reduced sedentariness and higher levels of light physical activity than those in monopharmacy. Rehabilitation efforts in psychiatric residential treatment facilities were likely to result in improved physical activity performances in residential patients. Our findings may have important public health implications, as they indicate the importance of reducing APP and encouraging physical activity.

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. Supplementary Information The online version contains supplementary material available at 10.1007/s12325-022-02232-z. Schizophrenia is a debilitating mental disorder that affects up to 1.6% of adults in the USA. Antipsychotic medications reduce symptoms of the disease, but many patients with schizophrenia are not fully adherent or choose to discontinue treatment entirely, increasing their risk of hospitalization. In others, efforts to achieve better symptom control or to avoid intolerable side effects may result in switching antipsychotic medications or adding additional medications, leading to higher medical treatment costs. The magnitude of these cost increases is unclear. This study sought to assess medical costs associated with antipsychotic treatment adherence, switching, and adding additional antipsychotics. We reviewed 81 studies published from January 2008 through June 2018 examining treatment adherence in patients with schizophrenia. We calculated rates of adherence, switching, and adding antipsychotics, as well as associated medical costs. Overall adherence to antipsychotic treatment was less than 50%, with up to 50% of patients switching medications and up to 29% adding an additional antipsychotic medication to their current treatment. Patients who were not treatment adherent incurred annual medical costs of $10,316 compared with $5723 in patients who were adherent. The costs of immediate or delayed switching of antipsychotic medications ranged from $21,922 to $28,232, while costs of adding an additional antipsychotic ranged from $24,045 to $29,344. These data suggest that suboptimal medication adherence, along with high rates of patient discontinuation and medication switching, lead to higher treatment costs in the management of patients with schizophrenia.

Abstract
AIM There is an ongoing debate regarding the optimal timing of discontinuation of antipsychotic drugs for patients with first episode psychosis. Although most guidelines recommend maintenance therapy for at least 1 or 2 years after reaching remission, study results indicate that early discontinuation may be beneficial for at least a subsample of patients. To date, little is known about which medication strategies are applied in patients recovering from a first psychotic episode. In this study, we examined the beliefs and practices of clinicians on medication discontinuation. METHODS We performed a survey among 50 experienced Dutch psychiatrists to assess how often specific treatment strategies have been applied in the past 12 months, as well as their knowledge and expectations with respect to medication discontinuation. RESULTS Psychiatrists estimated that, after remission, they continued medication at the same dose for at least 12 months in 51.2% of cases, continued in a reduced dose in 33.8% of cases and discontinued medication in 9.1% of cases after 4.4 months of remission on average. Although the medication is discontinued in only a relatively small proportion of patients, almost half of all clinicians (45.9%) used this strategy at least once in the past 12 months. CONCLUSIONS There is substantial practice variation in antipsychotic medication strategies after remission from a first psychotic episode. Future research on long-term effects of early medication discontinuation can guide clinicians in making evidence-based decisions when treating first-episode patients.

Abstract
OBJECTIVES One-third of the patients with schizophrenia show treatment resistance and literature on the effectiveness of interventions in patients with persistent symptoms is conflicting. This study aimed to assess clinical preferences of clinicians in those showing treatment resistance to antipsychotics and to determine correlates of interventions. METHODS Treatment strategies applied in the patients with schizophrenia in daily practice were inquired retrospectively. Those showing poor response to at least two antipsychotics and were administered a clinical intervention in a University Hospital between January and September 2018 were included. Clinical correlates of distinct interventions were evaluated. RESULTS The most common intervention (47%) was transition to a long-acting injectable antipsychotic (LAIA) and the second most common (22%) was addition of a second/third oral drug to on-going oral therapy. Switching to clozapine was more effective on positive symptoms comparing with the other interventions (p < 0.01). LAIA therapy showed a superiority over oral antipsychotic interventions at improving positive symptoms, except clozapine (p < 0.01). CONCLUSIONS LAIA administration and oral antipsychotic augmentation were the most common interventions in the patients with persistent symptoms. Clozapine was related to better clinical improvement in the present study and it might be administered as a second-line treatment in schizophrenia.Key pointsEffectiveness of the treatment strategies in schizophrenia patients with persistent symptoms is not satisfactory to meet expectations of the clinicians yet. Clozapine still seems to be the best option to provide a favourable improvement in TRS.LAIA and oral AP combination are used frequently in schizophrenia for persistent psychotic symptoms and targets of the combination therapies in daily practice needs to be clarified.The most common intervention was transition to a LAIA (47%) in the study and none of the patients administered LAIA had used a long-acting AP before the intervention. High rate of treatment nonadherence in schizophrenia is an important reason for common LAIA preference in the patients with persistent symptoms.Growing evidence indicates that clozapine can be used as a second-line treatment in schizophrenia, and thus, there is an urgent need to increase clozapine use in the patients with persistent symptoms in clinical practice.

Abstract
BACKGROUND Antipsychotic polypharmacy ("polypharmacy") involves the concurrent prescribing of two or more antipsychotics for managing schizophrenia. It occurs frequently despite there being limited clinical evidence for this practice and an increased risk of adverse events. Little is understood about why it occurs outside of treatment guidelines, highlighting a current research gap. OBJECTIVE To explore the factors contributing to non-evidence based polypharmacy practice and possible strategies for addressing these factors. METHODS Three focus groups were conducted between June and August 2018 with doctors and nurses employed at a mental health unit of a Western Australian public hospital. Participants were asked about their perceptions of polypharmacy, why it occurred and what could limit its prevalence. Thematic inductive analysis was mapped to the Theoretical Domains Framework to identify key underlying themes and to establish potential enablers and barriers for practice change. RESULTS Participants understood the risks of polypharmacy and perceived it to largely be perpetuated by external factors, out of which two key themes emerged: system-related issues (e.g.: communication failures whereby de-prescribing plans are not actioned); and patient-related issues (e.g.: misinformed views translating to medication-seeking behaviour). This led to the third theme: a disconnect between clinicians' knowledge and their practices (i.e.: being aware of Australian evidence-based guideline recommendations yet acknowledging polypharmacy still occurred due to the aforementioned issues). Strategies suggested to address these issues included developing medication management plans to bridge communication gaps and managing patients' medication expectations with education. CONCLUSIONS Management of schizophrenia is complex, requiring consideration of many patient-related and systemic factors. Polypharmacy has a place in certain contexts, however, must be well considered and closely monitored to allow for early identification of opportunities to rationalise (i.e.: de-prescribe) therapy, where appropriate. Future research objectives will centre on implementing strategies identified from these focus groups to optimise patient outcomes.

Korda AI, Andreou C, Borgwardt S. Pattern classification as decision support tool in antipsychotic treatment algorithms. Exp Neurol 2021; 339:113635. [PMID: 33548218 DOI: 10.1016/j.expneurol.2021.113635] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/20/2021] [Accepted: 02/01/2021] [Indexed: 10/22/2022]
Abstract
Pattern classification aims to establish a new approach in personalized treatment. The scope is to tailor treatment on individual characteristics during all phases of care including prevention, diagnosis, treatment, and clinical outcome. In psychotic disorders, this need results from the fact that a third of patients with psychotic symptoms do not respond to antipsychotic treatment and are described as having treatment-resistant disorders. This, in addition to the high variability of treatment responses among patients, enhances the need of applying advanced classification algorithms to identify antipsychotic treatment patterns. This review comprehensively summarizes advancements and challenges of pattern classification in antipsychotic treatment response to date and aims to introduce clinicians and researchers to the challenges of including pattern classification into antipsychotic treatment decision algorithms.

Abstract
Background: Tardive dyskinesia (TD) is an iatrogenic involuntary movement disorder occurring after extended antipsychotic use with unclear pathogenesis. CYP2D6 is a liver enzyme involved in antipsychotic metabolism and a well-studied gene candidate for TD. Materials & methods: We tested predicted CYP2D6 metabolizer phenotype with TD occurrence and severity in our two samples of European chronic schizophrenia patients (total n = 198, of which 82 had TD). Results: TD occurrence were associated with extreme metabolizer phenotype, controlling for age and sex (p = 0.012). In other words, individuals with either increased and no CYP2D6 activity were at higher risk of having TD. Conclusion: Unlike most previous findings, TD occurrence may be associated with both extremes of CYP2D6 metabolic activity rather than solely for poor metabolizers.

Abstract
PURPOSE To examine the prevalence of, and factors associated with, atypical antipsychotic use among U.S. pregnant women, and potential associations between early pregnancy atypical antipsychotic use and risk for 14 birth defects. METHODS We analyzed data from the National Birth Defects Prevention Study (1997-2011), a U.S. population-based case-control study examining risk factors for major structural birth defects. RESULTS Atypical antipsychotic use during pregnancy was more common among women with pre-pregnancy obesity, and women who reported illicit drug use before and during pregnancy, smoking during pregnancy, alcohol use during pregnancy, or use of other psychiatric medications during pregnancy. We observed elevated associations (defined as a crude odds ratio [cOR] ≥2.0) between early pregnancy atypical antipsychotic use and conotruncal heart defects (6 exposed cases; cOR: 2.3, 95% confidence interval [CI]: 0.9-6.1), and more specifically Tetralogy of Fallot (3 exposed cases; cOR: 2.5, 95% CI: 0.7-8.8), cleft palate (4 exposed cases, cOR: 2.5, 95% CI: 0.8-7.6), anorectal atresia/stenosis (3 exposed cases, cOR: 2.8, 95% CI: 0.8-9.9), and gastroschisis (3 exposed cases, cOR: 2.1, 95% CI: 0.6-7.3). CONCLUSIONS Our findings support the close clinical monitoring of pregnant women using atypical antipsychotics. Women treated with atypical antipsychotics generally access healthcare services before pregnancy; efforts to reduce correlates of atypical antipsychotic use might improve maternal and infant health in this population.

Abstract
BACKGROUND AND OBJECTIVE Antipsychotic polypharmacy (APP) is a controversial topic in the treatment of older adults with schizophrenia. The objective of this study was to examine the use of APP in older adult Asian patients with schizophrenia and its associated demographic and clinical factors. METHODS This study was based on the fourth survey of the consortium known as the Research on Asian Psychotropic Prescription Pattern for Antipsychotics. Fifteen Asian countries/territories participated in this survey, including Bangladesh, Mainland China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Myanmar, Pakistan, Singapore, Sri Lanka, Taiwan, Thailand, and Vietnam. Basic demographic and clinical characteristics were collected using a standardized data collection form. RESULTS Among the 879 older adults with schizophrenia included in the survey, the rate of APP was 40.5%. Multiple logistic regression analysis revealed that higher antipsychotic doses (P < .001, odds ratio [OR] = 1.003, 95% confidence interval [CI]: 1.002-1.003), longer duration of illness (P = .02, OR = 1.845, 95% CI: 1.087-3.132), and the prescription of anticholinergics (P < .001, OR = 1.871, 95% CI: 1.329-2.635), second-generation antipsychotics (P = .001, OR = 2.264, 95% CI: 1.453-3.529), and first-generation antipsychotics (P < .001, OR = 3.344, 95% CI: 2.307-4.847) were significantly associated with APP. CONCLUSION Antipsychotic polypharmacy was common in older adult Asian patients with schizophrenia. Compared to the results of previous surveys, the use of APP showed a declining trend over time. Considering the general poor health status of older patients with schizophrenia and their increased risk of drug-induced adverse events, the use of APP in this population needs careful consideration.

Abstract
INTRODUCTION The primary aim of this study was to compare clinical characteristics between the patients with schizophrenia on clozapine treatment with those under combination of long-acting injectable and oral antipsychotics (combined treatment), and the secondary aim was to evaluate the impact of obsessive-compulsive disorder (OCD) comorbidity on the clinical variables. METHODS The patients with schizophrenia applied at Outpatient Psychiatry Clinic of the University between October 2017 and March 2018 taking clozapine or combined treatment were included in the study. The participants were administered Brief Psychiatric Rating Scale (BPRS), Clinical Global Impressions Scale, Scale for the Assessment of Positive and Negative Symptoms (SAPS/SANS), Calgary Depression Scale for Schizophrenia (CDSS), Yale-Brown Obsessive Compulsive Scale (YBOCS), Turkish version of Schedule for Assessing the three components of insight (SAI), and Global Assessment of Functioning Scale (GAF). RESULTS Patients on clozapine had higher Y-BOCS, BPRS, SANS, CDSS scores, and lower GAF scores compared to those taking combined antipsychotics (p<0.05). OCD comorbidity rate was 13% in the combination therapy group and 36% in clozapine users. The SAPS scores were higher but CDSS scores were lower in clozapine users with the presence of OCD comorbidity (p<0.05). CONCLUSION Clozapine and combined therapy groups differed widely by the clinical characteristics of the patients in this study. Both groups showed a high OCD comorbidity rate in this study and OCD comorbidity should be considered when schizophrenia treatment is initiated to obtain more satisfactory results. Furthermore, patients on clozapine seem to show a different relationship with OCD comorbidity compared to those under combined treatment.

Abstract
Background The US FDA has designated pimozide, thioridazine, and ziprasidone as contraindicated for patients at risk of QT interval prolongation, and assigned haloperidol, olanzapine, paliperidone, quetiapine, and risperidone as associated with a significant risk of QT prolongation. This study aimed to examine trends and hospital variations in concomitant prescribing among these eight selected antipsychotics, and coprescription with interacting drugs known to increase QT prolongation risk. Methods Data on outpatient antipsychotic prescriptions during 2012-2015 were obtained from 16 general hospitals and 10 university hospitals nationwide. A time-series analysis was used for estimating trends in coprescription that led to drug interactions. Results Coprescribing among the eight antipsychotics ranged from 7.5% for quetiapine to 33.1% for thioridazine. The rate of coprescription with contraindicated interacting drugs was 9.7% for thioridazine and 21.9% for pimozide, and increased by 1.1 and 1.4 percentage points (% pt.) yearly for thioridazine in general and university hospitals, respectively. Coprescribing with interacting drugs with precautions was 2.8% for quetiapine, 7.4% for ziprasidone, and 27.9% for risperidone; these percentages increased yearly by 1.7% pt. for ziprasidone and 2.6% pt. for risperidone in general hospitals, as well as by 1.0% pt. for risperidone in university hospitals. The median proportion of patients exposed to a QT-prolonging interaction was 12.3% across hospitals (interquartile range, 9.9-19.5%). Wide interhospital variation was found in percentages of drug interactions among patients receiving thioridazine, ziprasidone, paliperidone, or olanzapine in general hospitals, and among patients receiving paliperidone or pimozide in university hospitals. Conclusions Coprescription of antipsychotics with interacting drugs that could increase the risk of QT prolongation was common in Thailand, and thioridazine, ziprasidone, and risperidone showed increasing trends. We urge the incorporation of a unified list of QT-prolonging antipsychotics and interacting drugs into a computerized drug interaction warning system, and existing national rational drug use campaigns should cover this important issue.

Abstract
OBJECTIVES Depression is a frequent but potentially treatable clinical dimension in patients with schizophrenia spectrum disorders (PWS). However, there is a lack of consensual recommendations regarding the optimal strategy to manage depression in PWS. In this study, we aimed to compare the various proposed strategies to define a core set of valid care recommendations for depression management in PWS. METHODS After a systematic search of the literature, the methodological quality of 10 international guidelines from four continents was compared using a validated guideline appraisal instrument (AGREE II). Key recommendations for the management of depression in PWS were subsequently reviewed and discussed. RESULTS The methodological quality of the guidelines was heterogeneous. Although all guidelines proposed pharmacotherapy, psychosocial interventions were a minor concern. Waiting for antipsychotic effects mostly was recommended during the acute phase of schizophrenia. During the postpsychotic phase of the illness, a switch to a second-generation antipsychotic and/or the adjunction of an antidepressant were the primary recommendations. Cognitive behavioural therapy and other medications were considered with strong variations. CONCLUSIONS Further studies are needed to strengthen the level of evidence for antidepressive approaches in PWS. The inclusion of PWS as stakeholders is also considered to be a major issue for future guideline development.

Abstract
AIM The aim of the present study was to survey the prevalence of antipsychotic polypharmacy and combined medication use across 15 Asian countries and areas in 2016. METHODS By using the results from the fourth survey of Research on Asian Prescription Patterns on antipsychotics, the rates of polypharmacy and combined medication use in each country were analyzed. Daily medications prescribed for the treatment of inpatients or outpatients with schizophrenia, including antipsychotics, mood stabilizers, anxiolytics, hypnotics, and antiparkinson agents, were collected. Fifteen countries from Asia participated in this study. RESULTS A total of 3744 patients' prescription forms were examined. The prescription patterns differed across these Asian countries, with the highest rate of polypharmacy noted in Vietnam (59.1%) and the lowest in Myanmar (22.0%). Furthermore, the combined use of other medications, expressed as highest and lowest rate, respectively, was as follows: mood stabilizers, China (35.0%) and Bangladesh (1.0%); antidepressants, South Korea (36.6%) and Bangladesh (0%); anxiolytics, Pakistan (55.7%) and Myanmar (8.5%); hypnotics, Japan (61.1%) and, equally, Myanmar (0%) and Sri Lanka (0%); and antiparkinson agents, Bangladesh (87.9%) and Vietnam (10.9%). The average psychotropic drug loading of all patients was 2.01 ± 1.64, with the highest and lowest loadings noted in Japan (4.13 ± 3.13) and Indonesia (1.16 ± 0.68), respectively. CONCLUSION Differences in psychiatrist training as well as the civil culture and health insurance system of each country may have contributed to the differences in these rates. The concept of drug loading can be applied to other medical fields.

Zhang W, Amos TB, Gutkin SW, Lodowski N, Giegerich E, Joshi K. A systematic literature review of the clinical and health economic burden of schizophrenia in privately insured patients in the United States. CLINICOECONOMICS AND OUTCOMES RESEARCH 2018; 10:309-320. [PMID: 29922078 PMCID: PMC5997131 DOI: 10.2147/ceor.s156308] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/26/2022] Open
Abstract
Purpose The aim of this study was to conduct a systematic literature review on the burden of schizophrenia in privately insured US patients. Materials and methods A systematic literature review of English language peer-reviewed journal articles of observational studies published from 2006 to 2016 was conducted using EMBASE/MEDLINE databases. Abstracts covering substantial numbers of patients with schizophrenia or schizoaffective disorder (i.e., N ≥ 100) were included for full-text review. Articles that did not clearly specify private insurance types were excluded. Results A total of 25 studies were reviewed; 10 included only privately insured patients; and 15 included a mix of different types of insurance. The review of the clinical burden of schizophrenia revealed the following: compared to patients with no mental disorders, those with schizophrenia had significantly increased odds of systemic disorders and both alcohol and substance abuse. Antipsychotic (AP) adherence was low, ranging from 31.5% to 68.7%. The medication possession ratio for AP adherence ranged from 0.22 to 0.73. The review of the health economic burden of schizophrenia revealed the following: patients with a recent (vs. chronic) diagnosis of schizophrenia had significantly higher frequencies of emergency department visits and hospitalizations and greater length of stay (LOS) and total annual per-capita costs. Mean all-cause hospitalizations and LOS decreased significantly after (vs. before) initiating long-acting injectable APs (LAIs). Patients also had significantly decreased mean all-cause, and schizophrenia-related, hospitalization costs after initiating LAIs. Total direct per-capita costs of care (but not pharmacy costs) for patients who were nonadherent to their oral APs within the first 90 days of their index event were significantly higher (vs. early adherent patients). Despite these potential benefits, only 0.25%–13.1% of patients were treated with LAIs across all studies. Conclusion Privately insured US patients with schizophrenia experience a substantial clinical and health economic burden related to comorbidities, acute care needs, nonadherence, and polypharmacy and have relatively low use of LAIs. Further study is warranted to understand prescribing patterns and clinical policies related to this patient population.

Correlates and predictors of antipsychotic drug polypharmacy in real-life settings: Results from a nationwide cohort study. Schizophr Res 2018; 192:213-218. [PMID: 28558905 DOI: 10.1016/j.schres.2017.05.015] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 05/01/2017] [Accepted: 05/12/2017] [Indexed: 11/28/2022]
Abstract
Reasons for using antipsychotic polypharmacy (APP) in routine clinical practice, despite a potentially unfavorable risk-benefit ratio, are poorly understood. This research aimed to determine (1) if severe courses of schizophrenia were associated with APP and (2) if a schizophrenia-related acute event would predict a switch to APP in the short term. Observational prospective data (at baseline and 6months) were drawn from a French nationwide cohort ("Cohorte Générale Schizophrénie"), which included 1859 inpatients and outpatients with schizophrenia. APP was defined as the prescription of ≥2 antipsychotic drugs (there being different active substances). Early-onset schizophrenia, legal guardianship, higher lifetime maximal severity of illness and comorbid antisocial personality were used as proxies for severe courses of schizophrenia. Schizophrenia-related acute events included hospitalization and recent suicide attempts. Logistic regression models were used to determine (1) whether the use of APP at baseline (vs. monotherapy) was associated with a severe course of schizophrenia or not, independent of acute events, and (2) if a switch to APP at 6months (vs. remaining on monotherapy) was associated with acute events, independent of severe courses of schizophrenia. Increased odds of APP use at baseline were independently associated with legal guardianship (OR=1.6; 95%CI=1.3, 2.0) and higher lifetime maximum severity of illness (OR=1.3; 95%CI=1.2, 1.5). A switch to APP at 6months was predicted by a hospitalization occurring since baseline (OR=6.1; 95%CI=3.9, 9.4). In routine clinical practice, APP is more likely prescribed to patients with severe courses of illness, possibly indicating the difficulty to manage these patients.

Clin Pract Epidemiol Ment Health 2017; 13:92-103. [PMID: 29081826 PMCID: PMC5633702 DOI: 10.2174/1745017901713010092] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Revised: 05/24/2017] [Accepted: 06/22/2017] [Indexed: 02/03/2023]
Abstract
Background: This study investigates the antipsychotic use patterns of patients with schizophrenia and its correlations in their daily drug use patterns. Methods: Patients with schizophrenia who have regular records at two different community counselling centres (CCS) were included in the study. Information about their medications and sociodemographic data was recorded through face-to-face interviews and supporting information about their drug use patterns was obtained from their relatives/caregivers/nurse. The Clinical Global Impression Scale (severity of illness) and the General Assessment of Functionality scales were also administered. Results: Patients with schizophrenia used 2.0 ± 0.81 antipsychotics daily and 3.52 ± 2.55 pills (1–18). Seventy-one percent of the patients used two or more kinds of psychotropic drugs. The most frequently used antipsychotics were quetiapine, a second generation antipsychotic, and haloperidol, a typical antipsychotic. Clinical severity, regular visits to a CCS and use of depot antipsychotics were independent predictors for polypharmacy. Conclusion: The rate of polypharmacy use is high in Turkey. There are multiple risk factors related with polipharmacy. New studies should focus risk factors for preventing polypharmacy.

A randomized, double-blind, comparison of the efficacy and safety of low-dose olanzapine plus low-dose trifluoperazine versus full-dose olanzapine in the acute treatment of schizophrenia. Schizophr Res 2017; 185:80-87. [PMID: 28109665 DOI: 10.1016/j.schres.2017.01.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2016] [Revised: 11/26/2016] [Accepted: 01/03/2017] [Indexed: 01/22/2023]
Abstract
OBJECTIVE Antipsychotic polypharmacy is common in clinical practice, but not recommended in guidelines for treating schizophrenia patients. This study aimed to compare the efficacy and safety of low-dose olanzapine plus low-dose trifluoperazine (a first-generation antipsychotic [FGA]) to full-dose olanzapine (a second-generation antipsychotic [SGA]) in the treatment of acute schizophrenia. METHOD In this 6-week, double-blind, fixed-dose study, patients were randomized to receive 5mg/day of olanzapine plus 5mg/day of trifluoperazine or 10mg/day of olanzapine for 6weeks. Efficacy measures, including the Positive and Negative Syndrome Scale (PANSS) and other scales, safety measures, side effect measures, and quality of life were assessed regularly. Response was defined as at least a 30% reduction in the PANSS total score. RESULTS Both groups were similar in: 1) baseline characteristics, 2) score changes in all efficacy measures, safety measures, side effect measures, and quality of life, and 3) response rates at each visit. The polypharmacy group with low-dose olanzapine did not have less weight gain and lower lipid levels than the monotherapy group with full-dose olanzapine. CONCLUSION Polypharmacy is as efficacious and safe as, but cheaper than, monotherapy in the acute treatment of schizophrenia. Whether our findings can be generalized to other combinations of an appropriate ratio of one FGA to another SGA dosage, which can achieve favorable clinical responses and side effect profiles, needs further investigation.

Abstract
Despite new insights into the pathophysiology of schizophrenia and clinical trials with highly selective drugs, no new therapeutic breakthroughs have been identified. We present a semi-mechanistic Quantitative Systems Pharmacology (QSP) computer model of a biophysically realistic cortical-striatal-thalamo-cortical loop. The model incorporates the direct, indirect and hyperdirect pathway of the basal ganglia and CNS drug targets that modulate neuronal firing, based on preclinical data about their localization and coupling to voltage-gated ion channels. Schizophrenia pathology is introduced using quantitative human imaging data on striatal hyperdopaminergic activity and cortical dysfunction. We identified an entropy measure of neuronal firing in the thalamus, related to the bandwidth of information processing that correlates well with reported historical clinical changes on PANSS Total with antipsychotics after introduction of their pharmacology (42 drug-dose combinations, r2=0.62). This entropy measure is further validated by predicting the clinical outcome of 28 other novel stand-alone interventions, 14 of them with non-dopamine D2R pharmacology, in addition to 8 augmentation trials (correlation between actual and predicted clinical scores r2=0.61). The platform predicts that most combinations of antipsychotics have a lower efficacy over what can be achieved by either one; negative pharmacodynamical interactions are prominent for aripiprazole added to risperidone, haloperidol, quetiapine and paliperidone. The model also recapitulates the increased probability for psychotic breakdown in a supersensitive environment and the effect of ketamine in healthy volunteers. This QSP platform, combined with similar readouts for motor symptoms, negative symptoms and cognitive impairment has the potential to improve our understanding of drug effects in schizophrenia patients.

Abstract
This study assessed real-world treatment patterns and antipsychotic (AP) medication adherence among commercially insured US patients with schizoaffective disorder (SCA). Continuously insured adults aged 18 years or older with a diagnosis of SCA from January 1, 2009, to December 31, 2012, were identified from the Clinformatics Data Mart database. Patients were categorized into 2 cohorts: incident or prevalent SCA. Demographics and clinical characteristics were evaluated during the baseline period. Use of psychiatric medications and adherence to AP medications were evaluated during a 12-month follow-up period after index diagnosis of SCA. Of the overall study population (N = 2713; mean age, 40.2 y; 52.7% female), 1961 patients (72.3%) (mean age, 38.7 y; 51.3% female) had incident SCA, and 752 patients (27.7%) (mean age, 43.9 y; 56.5% female) had prevalent SCA. Antipsychotics were used by 74.8% of patients in the overall study population during the follow-up period. The most commonly prescribed oral AP was risperidone (23.9%), followed by quetiapine (21.4%) and aripiprazole (20.4%). Use of any long-acting injectable APs in the overall study population during the follow-up period was less than 3%. A total of 49.0% and 38.0% of the overall study population had medication possession ratios and proportion of days covered for APs of 80% or greater, respectively. Overall use of long-acting injectable APs for the treatment of SCA is low, and adherence to AP medications, measured by both medication possession ratio and proportion of days covered, is suboptimal among patients with SCA in the real-world setting.

Abstract
Within medicinal chemistry nowadays, the so-called pharmaco-dynamics seeks for qualitative (for understanding) and quantitative (for predicting) mechanisms/models by which given chemical structure or series of congeners actively act on biological sites either by focused interaction/therapy or by diffuse/hazardous influence. To this aim, the present review exposes three of the fertile directions in approaching the biological activity by chemical structural causes: the special computing trace of the algebraic structure-activity relationship (SPECTRAL-SAR) offering the full analytical counterpart for multi-variate computational regression, the minimal topological difference (MTD) as the revived precursor for comparative molecular field analyses (CoMFA) and comparative molecular similarity indices analysis (CoMSIA); all of these methods and algorithms were presented, discussed and exemplified on relevant chemical medicinal systems as proton pump inhibitors belonging to the 4-indolyl,2-guanidinothiazole class of derivatives blocking the acid secretion from parietal cells in the stomach, the 1-[(2-hydroxyethoxy)-methyl]-6-(phenylthio)thymine congeners’ (HEPT ligands) antiviral activity against Human Immunodeficiency Virus of first type (HIV-1) and new pharmacophores in treating severe genetic disorders (like depression and psychosis), respectively, all involving 3D pharmacophore interactions.

Abstract
OBJECTIVES The goal of this study was to explore antipsychotic medication prescribing practices in a sample of 86,034 patients discharged from state psychiatric inpatient hospitals and to find the prevalence of patients discharged with no antipsychotic medications, on antipsychotic monotherapy, and on antipsychotic polypharmacy. For patients discharged on antipsychotic polypharmacy, the study explored the adjusted rates of antipsychotic polypharmacy, the reasons patients were discharged on antipsychotic polypharmacy, the proportion of antipsychotic polypharmacy by mental health disorder, and the characteristics associated with being discharged on antipsychotic polypharmacy. METHODS This cross-sectional study analyzed all discharges for adult patients (18 to 64 y of age) from state psychiatric inpatient hospitals between January 1 and December 31, 2011. The relationship among variables was explored using χ, t test, and analysis of variance. Logistic regression was used to determine predictors of antipsychotic polypharmacy. RESULTS The prevalence of antipsychotic polypharmacy was 12%. Of the discharged patients receiving at least 1 antipsychotic medication (adjusted rate), 18% were on antipsychotic polypharmacy. The strongest predictors of antipsychotic polypharmacy being prescribed were having a diagnosis of schizophrenia and a length of stay of 90 days or more. Patients were prescribed antipsychotic polypharmacy primarily to reduce their symptoms. CONCLUSIONS Antipsychotic polypharmacy continues at a high enough rate to affect nearly 10,000 patients with a diagnosis of schizophrenia each year in state psychiatric inpatient hospitals. Further analysis of the clinical presentation of these patients may highlight particular aspects of the illness and its previous treatment that are contributing to practices outside the best-practice guideline. An increased understanding of trend data, patient characteristics, and national benchmarks provides an opportunity for decision-making that is sensitive to the patient's needs and cognizant of the hospital's accomplishments in adopting best practices.

Abstract
Background There is a surge of cardiovascular disease (CVD) in Africa. CVD is the leading cause of mortality among patients with severe mental illness (SMI) in developed countries, with little evidence from the African context. Objective To determine the prevalence and risk factors for MetS among South African patients with SMI. Method In a cross sectional study, individuals with SMI treated with antipsychotics and a control group without a mental illness, matched for age, gender and ethnicity were evaluated for MetS using the 2009 Joint Interim statement (JIS) criteria. Results Of the 276 study group subjects, 65.9% were male, 84.1% black African, 9.1% white, 5.4% of Indian descent and 1.5% coloured (mixed race) with a mean age of 34.7 years (±12.5). Schizophrenia was the most common diagnosis (73.2%) and 40% were taking first generation antipsychotics. The prevalence of MetS was 23.2% (M: 15.4%, F: 38.3%) in the study group and 19.9% (M: 11.9%, F: 36.3%) in the control group (p = 0.4). MetS prevalence was significantly higher in study subjects over 55 years compared to controls (p = 0.03). Increased waist circumference (p< 0.001) and low high density lipoprotein (HDL) cholesterol (p = 0.003) were significantly more prevalent in study subjects compared to controls. In study subjects, risk factors associated with MetS included age (OR: 1.09, 95% CI 1.06–1.12, p < 0.001), female gender (OR: 2.19, 95% CI 1.06–4.55, p = 0.035) and Indian descent (OR: 5.84, 95% CI 1.66–20.52, p = 0.006) but not class of antipsychotic (p = 0.26). Conclusion The overall MetS prevalence was not increased in patients with SMI compared to controls; however, the higher prevalence of the individual components (HDL cholesterol and waist circumference) suggests an increased risk for CVD, especially in patients over 55 years.
