Abstract
PURPOSE/BACKGROUND It is still not well known whether antipsychotic monotherapy versus polypharmacy differs in terms of efficacy in the emergency department (ED) utilization, presentation with agitation/aggression, and rehospitalization in schizophrenia spectrum disorders (SSD) patients. This study aimed to determine the effectiveness of antipsychotic monotherapy and polypharmacy for these outcomes in the real world. METHODS/PROCEDURES The study was conducted with electronic health records of 669 SSD patients admitted to the ED. Patients were evaluated in 4 groups according to antipsychotic use at the first admission to ED: antipsychotic noncompliance for more than 90 days, antipsychotic noncompliance for 15 to 90 days, antipsychotic monotherapy, and polypharmacy. All patients followed up for at least 1 year after index admission. The primary outcomes determined an association between antipsychotic monotherapy versus polypharmacy and all-cause psychiatric hospitalization between the groups after index admission in the SSD. FINDINGS/RESULTS The groups, including patients with antipsychotic noncompliance, had higher ED visits, more hospitalizations, and more admissions with agitation/aggression compared with antipsychotic monotherapy or polypharmacy. However, no differences were found between monotherapy and polypharmacy groups regarding these outcomes. In addition, there was no difference in the risk of hospitalization in monotherapy antipsychotic users compared with polypharmacy users. Patients discharged with monotherapy or polypharmacy also had similar rehospitalization rates at follow-up. IMPLICATIONS/CONCLUSIONS There is no positive evidence that recommending polypharmacy over antipsychotic monotherapy is superior with regard to the resulting frequency of ED visits, ED admissions with agitation/aggression, hospitalization, and rehospitalization. In this context, antipsychotic monotherapy may be preferred over polypharmacy in patients who are not resistant to treatment.

Abstract
Schizophrenia is a chronic psychiatric disease that is characterized by psychotic symptoms, including positive, negative, affective, and aggressive symptoms, as well as cognitive dysfunction, and is primarily treated using drug therapy, the continuation of which is essential to prevent recurrence/recrudescence. Various second-generation antipsychotics with pharmacological properties or adverse events that differ from those of conventional antipsychotics have recently been introduced, and pharmaceutical management is required for drug efficacy assessments and adverse event monitoring/management of these drugs. Antipsychotic monotherapy (APM) is the gold standard treatment for schizophrenia and is recommended in various guidelines. However, a subgroup of patients with schizophrenia do not or only partially respond to APM. Therefore, antipsychotic polypharmacy (APP), in which ≥2 antipsychotics are combined, has been routinely utilized to compensate for insufficient responses to APM in clinical practice. APP has recently been proposed as an evidence-based treatment option, but does not consider clinicians' experience. However, the risk of APP-related adverse events is high. The application of APP needs to be carefully reviewed, whilst taking into consideration patient backgrounds. Furthermore, the risk of APP-related adverse events is higher in elderly patients than in the general population; therefore, caution is needed. This review discusses the merits of APP, matters that need to be considered, and a switch from APP to APM, and also focuses on the application of APP in clinical practice.

Abstract
Introduction Polypharmacy is commonly associated with adverse health outcomes. There are currently no meta-analyses of the prevalence of polypharmacy or factors associated with polypharmacy. We aimed to estimate the pooled prevalence of polypharmacy and factors associated with polypharmacy in a systematic review and meta-analysis. Methods MEDLINE, EMBASE, and Cochrane databases were searched for studies with no restrictions on date. We included observational studies that reported on the prevalence of polypharmacy among individuals over age 19. Two reviewers extracted study characteristics including polypharmacy definitions, study design, setting, geography, and participant demographics. The risk of bias was assessed using the Newcastle-Ottawa Scales. The main outcome was the prevalence of polypharmacy and factors associated with polypharmacy prevalence. The pooled prevalence estimates of polypharmacy with 95% confidence intervals were determined using random effects meta-analysis. Subgroup analyses were undertaken to evaluate factors associated with polypharmacy such as polypharmacy definitions, study setting, study design and geography. Meta-regression was conducted to assess the associations between polypharmacy prevalence and study year. Results 106 full-text articles were identified. The pooled estimated prevalence of polypharmacy in the 54 studies reporting on polypharmacy in all medication classes was 37% (95% CI: 31-43%). Differences in polypharmacy prevalence were reported for studies using different numerical thresholds, study setting, and publication year. Sex, study geography, study design and geographical location were not associated with differences in polypharmacy prevalence. Discussion Our review highlights that polypharmacy is common particularly among older adults and those in inpatient settings. Clinicians should be aware of populations who have an increased likelihood of experiencing polypharmacy and efforts should be made to review the appropriateness of prescribed medications and occurrence of adverse effects potentially associated with polypharmacy. Conclusions and implications Clinicians should be aware of the common occurrence of polypharmacy and undertake efforts to minimize inappropriate polypharmacy whenever possible.

Abstract
BACKGROUND Antipsychotic polypharmacy and prescription of high-dose antipsychotics are often used for the treatment of psychotic symptoms, especially in compulsory psychiatric care although there is lack of evidence to support this practice and related risks for patients. AIMS We aimed to investigate prescription patterns in patients with psychosis under compulsory psychiatric treatment in Cyprus and to identify predictors for pharmaceutic treatment patterns. METHOD This was a nationwide, descriptive correlational study with cross-sectional comparisons, including 482 patients with compulsory admission to hospital. Sociodemographic and clinical data were collected. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Prescribed medication patterns, including use of medication pro re nata (PRN, when required), were recorded. RESULTS Antipsychotic polypharmacy with a PRN schema was reported in 33.2% (n = 160) of the participants. Polypharmacy without a PRN schema was reported in 5.6% (n = 27) of the participants. We found that 27.2% (n = 131) of the participants were prescribed high-dose antipsychotics without PRN included; and 39.2% (n = 189) prescribed high-dose antipsychotics with PRN included. In the logistic regression analyses, predictors for prescription of high-dose antipsychotics were male gender, positive psychiatric history, receiving state benefits and a negative history of substance use. Male gender was the only predictor for polypharmacy without a PRN schema whereas male gender, negative family psychiatric history, receiving state benefits and the total score on the positive symptoms PANSS subscale were predictors for polypharmacy with a PRN schema included. CONCLUSIONS A high frequency of polypharmacy and use of medication PRN beyond clinical guidelines has been reported for the first time in psychiatric compulsory care in Cyprus; revision in antipsychotic prescription is needed.

Abstract
Schizophrenia is a debilitating illness with a lifetime prevalence estimate of 0.6% and consists of symptoms from the positive, negative, and cognitive domains. Social support, therapy, psychoeducation, and overall case management are very important aspects of the treatment of schizophrenia. However, as abnormalities in neurotransmission are one of the key findings of schizophrenia pathology, pharmacotherapies are cornerstones of the management of schizophrenia. Antipsychotics have been used as the primary pharmacological treatment of schizophrenia. These agents often have a good effect on reducing positive symptoms, but may not markedly improve negative symptoms or cognitive defects. However, at least 20% of individuals with schizophrenia do not experience a substantial response from monotherapy with antipsychotics. Further, despite evolving treatment protocols and advances in early recognition of the disorder, 70% of patients with schizophrenia require long-term, even lifetime, medication to control their symptoms and do not achieve complete recovery. To address these shortcomings, clinicians and research scientists have explored different combinations of treatments, polypharmacy, to improve the treatment of patients. Antipsychotic polypharmacy has been shown to cause more side effects than monotherapy, which is the main reason why most treatment guidelines caution against it. Antipsychotic monotherapy should be strived for and clozapine should be tried at the latest if two monotherapy trials with other antipsychotics have failed and no absolute contraindications exist. If residual symptoms exist despite trials of adequate dose and duration, other reasons that may reduce treatment effect should be ruled out. Long-acting injectables or blood concentration measurements should be considered to affirm compliance and proper serum levels. Antipsychotic polypharmacy should be considered and discussed with patients from whom the aforementioned procedures do not produce a satisfactory treatment result. In some cases, antipsychotic polypharmacy may produce better results than other forms of treatment augmentation, such as benzodiazepines. In particular, combining aripiprazole with clozapine may be effective in reducing treatment side effects or residual symptoms, and this is likely to hold true for combining other partial dopamine D2 agonists with clozapine as well, although currently scant data exist. More research is needed, both in controlled but also real-world settings, to define optimal antipsychotic polypharmacy and/or other psychotropic treatment augmentation strategies for specific patient groups and situations.

Abstract
Antipsychotic polypharmacy (APP) is a psychopharmacological practice in which two or more antipsychotics are prescribed simultaneously. Despite the absence of evidence to support it, it is highly prevalent in clinical settings. Another recurrent practice strongly associated with APP is the prescription of high-dose antipsychotics (HDAs). Compulsory treatment is a legal means to impose treatment on an individual suffering from mental illness who refuses therapeutic intervention. Compulsory treatment has been associated with APP and HDAs and rates of both have been proposed to represent indicators of the quality of prescribing. We aimed to perform an antipsychotic prescription audit in a vulnerable psychiatric population, at the psychiatry department of a district hospital in Portugal, across 7 years. We evaluated APP and HDAs in 403 compulsorily admitted patients by reviewing their files at discharge. We used logistic regression to search for factors associated with APP and HDAs. APP was found in 70.5% of individuals, whereas HDAs were found in 51.4%. After adjustment, APP was significantly associated with male gender (Odds Ratio[OR] = 1.85 [1.04; 3.30] 95% Confidence Interval [CI]), involuntary outpatient treatment (OR = .40 [.18; .82] 95% CI), activation of the hospital social services (OR = 1.91 [1.08; 3.38] 95%CI), prescription of antidepressants (OR = .43 [.22; .82] 95%CI) and long-acting injectables (LAI) (OR = 28.29 [13.13; 60.97] 95%CI). HDAs were associated with male gender (OR = 1.76 [1.06; 2.94] 95%CI), the prescription of LAI (OR = 12.92 [6.93; 24.09] 95%CI) and oral first-generation antipsychotics (OR = 2.90 [1.51; 5.60] 95%CI).

Abstract
BACKGROUND This prospective cohort study aimed at evaluating patterns of polypharmacy and aggressive and violent behavior during a 1-year follow-up in patients with severe mental disorders. METHODS A total of 340 patients (125 inpatients from residential facilities and 215 outpatients) were evaluated at baseline with the Structured Clinical Interview for DSM-IV Axis I and II, Brief Psychiatric Rating Scale, Specific Levels of Functioning scale, Brown-Goodwin Lifetime History of Aggression, Buss-Durkee Hostility Inventory, Barratt Impulsiveness Scale, and State-Trait Anger Expression Inventory-2. Aggressive behavior was rated every 15 days with the Modified Overt Aggression Scale and treatment compliance with the Medication Adherence Rating Scale. RESULTS The whole sample was prescribed mainly antipsychotics with high levels of polypharmacy. Clozapine prescription and higher compliance were associated with lower levels of aggressive and violent behavior. Patients with a history of violence who took clozapine were prescribed the highest number of drugs. The patterns of cumulative Modified Overt Aggression Scale mean scores of patients taking clozapine (n = 46), other antipsychotics (n = 257), and no antipsychotics (n = 37) were significantly different (P = .001). Patients taking clozapine showed a time trend at 1-year follow-up (24 evaluations) indicating a significantly lower level of aggressive behavior. Patient higher compliance was also associated with lower Modified Overt Aggression Scale ratings during the 1-year follow-up. CONCLUSION Both inpatients and outpatients showed high levels of polypharmacy. Clozapine prescription was associated with lower Modified Overt Aggression Scale ratings compared with any other antipsychotics or other psychotropic drugs. Higher compliance was associated with lower levels of aggressive and violent behavior.

Abstract
Schizophrenia is a severe mental disorder characterized by a heterogeneous symptom profile which comprises a clinical platform for widespread use of polypharmacy even though antipsychotic monotherapy is the recommended treatment regimen. This narrative review provides a summary of the current gap between evidence and practice for use of antipsychotic combination therapy in patients with schizophrenia. Antipsychotic polypharmacy is frequently prescribed instead of following international consensus of clozapine monotherapy in treatment-resistant patients. Antipsychotic-benzodiazepine combination therapy clearly has a role in the treatment of acute agitation whereas there is no evidence to support an effect on core schizophrenia symptoms when chronically prescribed. Antidepressants are typically added to antipsychotic treatment in case of persistent negative symptoms. Available evidence suggests that antidepressants may improve negative symptom control in schizophrenia. Combining an antipsychotic with an antiepileptic is not supported by any firm evidence, but individual mood stabilizers have come out positively in single trials. Generally, the evidence base for polypharmacy in schizophrenia maintenance treatment is sparse but may be warranted in certain clinical situations. Therapeutic benefits and side effects should be carefully monitored and considered to ensure a beneficial risk-benefit ratio if prescribing polypharmacy for specific clinical indications.

Abstract
BACKGROUND Schizophrenia is one of the leading public health issues in psychiatry and imposes a heavy financial burden on the healthcare systems. This study aims to report the direct medical costs and the associated factors for patients with schizophrenia in Guangzhou city, Southern China. METHODS This was a retrospective 4-year cohort study. Data were obtained from urban health insurance claims databases of Guangzhou city, which contains patients' sociodemographic characteristics, direct medical costs of inpatient and outpatient care. The study cohort (including all the reimbursement claims submitted for schizophrenia inpatient care during November 2010 and October 2014) was identified using the International Classification of Diseases Tenth version (F20). Their outpatient care information was merged from outpatient claims database. Descriptive analysis and the multivariate regression analysis based on Generalized Estimating Equations model were conducted. RESULTS A total of 2971 patients were identified in the baseline. The cohort had a mean age of 50.3 years old, 60.6% were male, and 67.0% received medical treatment in the tertiary hospitals. The average annual length of stay was 254.7 days. The average annual total direct medical costs per patient was 41,972.4 Chinese Yuan (CNY) ($6852.5). The inpatient costs remained as the key component of total medical costs. The Urban Employee Basic Medical Insurance enrollees with schizophrenia had higher average costs for hospitalization (CNY42,375.1) than the Urban Resident Basic Medical Insurance enrollees (CNY40,917.3), and had higher reimbursement rate (85.8% and 61.5%). The non-medication treatment costs accounted for the biggest proportion of inpatient costs for both schemes (55.8% and 64.7%). Regression analysis suggested that insurance type, age, hospital levels, and length of stay were significantly associated with inpatient costs of schizophrenia. CONCLUSIONS The direct annual medical costs of schizophrenia were high and varied by types of insurance in urban China. The findings of this study provide vital information to understand the burden of schizophrenia in China. Results of this study can help decision-makers assess the financial impact of schizophrenia.

Abstract
PURPOSE To provide an overview on the magnitude of the impact of schizophrenia on the healthcare system in Europe and to gain a better understanding on the most important factors influencing the variation of costs. METHODS Studies reporting costs and healthcare utilization among patients with schizophrenia were searched in MEDLINE (via Scopus), EMBASE (via Scopus) and Cochrane Database of Systematic Reviews on 19th January 2017. RESULTS Twenty-three studies, from the 1075 references initially identified, were included in this review. The annual cost per patient ranged from €533 in Ukraine to €13,704 in the Netherlands. Notably drug costs contributed to less than 25% of the direct healthcare cost per patient in every country, which might be explained by similar pharmaceutical prices among countries due to the reference pricing system applied in Europe. Inpatient costs were the largest component of health service costs in the majority of the countries. Despite methodological heterogeneity across studies, four major themes could be identified (age, severity of symptoms, continuation of treatment/persistence, hospitalization) that have substantial impact on the costs of schizophrenia. CONCLUSIONS Schizophrenia represents a substantial cost for the healthcare system in Europe driven by the high cost per patient. Substantial savings could potentially be achieved by increasing investment in the following areas: (1) reducing the number of hospitalizations e.g. by increasing the efficiency of outpatient care; (2) working out interventions targeted at specific symptoms; (3) improving patient persistence and adherence in antipsychotic therapy.

Abstract
OBJECTIVES The aim of this study was to determine if there was an association between being discharged on antipsychotic polypharmacy (APP) and risk of readmission into secondary mental health care. METHODS Using data from the South London and Maudsley (SLAM) case register, service users with serious mental illness (SMI), discharged between 1st January 2007 and 31th December 2014, were followed up for 6 months. Patients were classified as receiving either monotherapy or polypharmacy at index discharge. Multivariable Cox regression models were constructed, adjusting for sociodemographic, socioeconomic, clinical and service use factors. RESULTS We identified 5523 adults who had been admitted at least once to SLAM, of whom 1355 (24.5%) were readmitted into secondary mental health care. In total, 15% (n = 826) of patients were discharged on APP and 85% (n = 4697) on monotherapy. Of these, 30.9% (n = 255) and 23.4% (n = 1100) were readmitted respectively. Being discharged on APP was associated with a significantly increased risk of readmission, in comparison to patients discharged on monotherapy (HR = 1.4, 1.2-1.7, p < 0.001). This association was maintained in the fully adjusted model and following several sensitivity analyses. We further established that patients receiving clozapine APP (n = 200) were at a significantly increased risk for readmission in comparison to patients on clozapine monotherapy (HR = 1.8, 1.2-2.6, p = 0.008). CONCLUSIONS Our results suggest that patients discharged on APP are more likely to be readmitted into hospital within 6 months in comparison to those discharged on monotherapy. This needs to be considered in treatment decisions and the reasons for the association clarified.

Abstract
Atypical antipsychotics (AAP) are the prevailing form of schizophrenia treatment today due to their low side effects and superior efficacy. Nevertheless, some issues still need to be addressed. First, there are still a large number of patients with treatment-resistant schizophrenia (TRS), which has led to a growing trend to resort to AAP polypharmacy with few side effects. Most clinical treatment guidelines recommend clozapine monotherapy in TRS, but around one third of schizophrenic patients fail to respond to clozapine. For these patients, with clozapine-resistant schizophrenia AAP polypharmacy is a common strategy with a continually growing evidence base. Second, AAP generally have great risks for developing metabolic syndrome, such as weight gain, abnormality in glucose, and lipid metabolism. These metabolic side effects have become huge stumbling blocks in today's schizophrenia treatment that aims to improve patients' quality of life as well as symptoms. The exact reasons why this particular syndrome occurs in patients treated with AAP is as yet unclear though factors such as interaction of AAP with neurotransmitter receptors, genetic pholymorphisms, type of AAPs, length of AAP use, and life style of schizophrenic patients that may contribute to its development. The present article aimed to review the evidence underlying these key issues and provide the most reasonable interpretations to expand the overall scope of antipsychotics usage.

Abstract
Background it is still equivocal whether there is a potential role of late-life physical activity in ameliorating the challenges of increasing healthcare expenditure due to the consequence of global population ageing. Objective this study aimed to examine the prospective association between physical activity and subsequent hospital care utilisation in older adults and to explore the optimal dose of physical activity required to reduce hospital care utilisation. Design this was a prospective cohort study based on the data from the Taiwan 2005 National Health Interview Survey, which were linked to the 2005-12 claims data from the National Health Insurance system. Participants 1,760 older adults aged 65 or more. Methods the frequency, duration and intensity for physical activity were assessed, and total physical activity energy expenditure was estimated. The average annualised hospital care utilisation for the period 2006 through 2012, including number of hospitalisations, number of days in hospital and the costs of hospitalisation, were calculated. Results older adults engaging in at least moderate volume of physical activity (≥1,000 kcal/week) experienced fewer subsequent hospital admissions and fewer days in hospital than did sedentary individuals, after adjusting for covariates. Trends for reduced hospitalisation costs were also found. These associations persisted in sensitivity analyses, including tests of reverse causation. Conclusion this study has provided evidence that older adults who are at least moderately active may minimise utilisation of hospital care services. The findings highlight the importance of maintaining a physically active lifestyle in later life.

Abstract
Antipsychotic polypharmacy in schizophrenia is much debated, since it is common and costly with unclear evidence for its efficacy and safety. We conducted a systematic literature search and a random effects meta-analysis of randomized trials comparing augmentation with a second antipsychotic vs. continued antipsychotic monotherapy in schizophrenia. Co-primary outcomes were total symptom reduction and study-defined response. Antipsychotic augmentation was superior to monotherapy regarding total symptom reduction (16 studies, N=694, standardized mean difference, SMD=-0.53, 95% CI: -0.87 to -0.19, p=0.002). However, superiority was only apparent in open-label and low-quality trials (both p<0.001), but not in double-blind and high-quality ones (p=0.120 and 0.226, respectively). Study-defined response was similar between antipsychotic augmentation and monotherapy (14 studies, N=938, risk ratio = 1.19, 95% CI: 0.99 to 1.42, p=0.061), being clearly non-significant in double-blind and high-quality studies (both p=0.990). Findings were replicated in clozapine and non-clozapine augmentation studies. No differences emerged regarding all-cause/specific-cause discontinuation, global clinical impression, as well as positive, general and depressive symptoms. Negative symptoms improved more with augmentation treatment (18 studies, N=931, SMD=-0.38, 95% CI: -0.63 to -0.13, p<0.003), but only in studies augmenting with aripiprazole (8 studies, N=532, SMD=-0.41, 95% CI: -0.79 to -0.03, p=0.036). Few adverse effect differences emerged: D2 antagonist augmentation was associated with less insomnia (p=0.028), but more prolactin elevation (p=0.015), while aripiprazole augmentation was associated with reduced prolactin levels (p<0.001) and body weight (p=0.030). These data suggest that the common practice of antipsychotic augmentation in schizophrenia lacks double-blind/high-quality evidence for efficacy, except for negative symptom reduction with aripiprazole augmentation.

Abstract
PURPOSE The emergence of electronic prescribing devices with clinical decision support systems (CDSS) is able to significantly improve management pharmacological treatments. We developed a web application available on smartphones in order to help clinicians monitor prescription and further propose CDSS. METHOD A web application (www.MEmind.net) was developed to assess patients and collect data regarding gender, age, diagnosis and treatment. We analyzed antipsychotic prescriptions in 4345 patients attended in five Psychiatric Community Mental Health Centers from June 2014 to October 2014. The web-application reported average daily dose prescribed for antipsychotics, prescribed daily dose (PDD), and the PDD to defined daily dose (DDD) ratio. RESULTS The MEmind web-application reported that antipsychotics were used in 1116 patients out of the total sample, mostly in 486 (44%) patients with schizophrenia related disorders but also in other diagnoses. Second generation antipsychotics (quetiapine, aripiprazole and long-acting paliperidone) were preferably employed. Low doses were more frequently used than high doses. Long acting paliperidone and ziprasidone however, were the only two antipsychotics used at excessive dosing. Antipsychotic polypharmacy was used in 287 (26%) patients with classic depot drugs, clotiapine, amisulpride and clozapine. CONCLUSIONS In this study we describe the first step of the development of a web application that is able to make polypharmacy, high dose usage and off label usage of antipsychotics visible to clinicians. Current development of the MEmind web application may help to improve prescription security via momentary feedback of prescription and clinical decision support system.

Abstract
BACKGROUND Although pharmacotherapy is one of the most important treatments for schizophrenia, the prominent levels of antipsychotic polypharmacy and high-dose regimens used in Japan are thought to be inconsistent with treatment regimens used in other countries. In this study, we evaluated the effect of pharmacist intervention on physician prescribing in patients with chronic schizophrenia. METHODS Participants comprised 52 inpatients at Sawa Hospital (Osaka, Japan), treated with at least one antipsychotic agent, who received pharmacist intervention for 1 year (2012). We compared the dose and the number of antipsychotics prescribed, and the rate of concurrent prescribing of anti-Parkinson, benzodiazepine and mood-stabilizer medication, pre- and post-pharmacist intervention. As an indicator of psychosis symptoms, the rate of seclusion room use was recorded. Additionally, we evaluated the impact of pharmacist intervention on medicine costs. Continuous variables were analyzed by Wilcoxon signed-rank sum tests, and categorical data were analyzed using Fisher's exact tests. RESULTS Compared with pre-intervention, the dose (982.6 mg pre vs. 857.6 mg post; p < 0.01) and the number of antipsychotics (2.0 pre vs. 2.0 post; p < 0.05) at 1 year were significantly lower post-intervention. The seclusion room use rate was not significantly different but tended to be lower post-intervention than pre-intervention (p < 0.1). The cost (in USD) for all medicines (10.33 pre vs. 8.76 post; p < 0.05), antipsychotics (8.04 pre vs. 6.48 post; p < 0.05), and psychotropics (9.24 pre vs. 7.68 post; p < 0.01) were significantly lower post-intervention than pre-intervention. CONCLUSION Pharmacist intervention has the potential to optimize medication prescribing and reduce medication costs in patients with chronic schizophrenia. It might be suggested that clinical practitioners as well as medical hospital administrators consider the pharmacists' ability to rationalize medication therapy in schizophrenia.

Abstract
INTRODUCTION Antipsychotic co-treatment is common in schizophrenia, despite lacking evidence for its efficacy and safety. Areas: We conducted a systematic search of PubMed/PsycInfo/CJN/WangFan/CBM without language restrictions from database inception until 05/25/2015 for randomized trials comparing antipsychotic monotherapy with antipsychotic co-treatment in ≥20 adults with schizophrenia reporting meta-analyzable adverse events (AEs) data. Meta-analyzing 67 studies (n=4,861, duration=10.3±5.2 weeks), antipsychotic co-treatment was similar to monotherapy regarding intolerability-related discontinuation (risk ratio (RR)=0.84, 95% confidence interval (CI)=0.53-1.33, p=0.455). While incidence of ≥1 AE was lower with antipsychotic co-treatment (RR=0.77, 95%CI=0.66-0.90, p=0.001), these results were solely driven by open-label and efficacy-focused studies. Adjunctive D2-antagonists lead to less nausea (RR=0.220, 95%CI=0.06-0.87, p=0.030) and insomnia (RR=0.26, 95%CI=0.08-0.86, p=0.028), but higher prolactin (SMD=2.20, 95%CI=0.43-3.96, p=0.015). Conversely, adjunctive partial D2-agonists (aripiprazole=100%) resulted in lower electrocardiogram abnormalities (RR=0.43, 95%CI=0.25-0.73, p=0.002), constipation (RR=0.45, 95%CI=0.25-0.79, p=0.006), drooling/hypersalivation (RR=0.14, 95%CI=0.07-0.29, p<0.001), prolactin (SMD=-1.77, 95%CI=-2.38, -1.15, p<0.001), total and LDL-cholesterol (SMD=-0.33, 95%CI=-0.55, -0.11, p=0.003; SMD=-0.33, 95%CI=-0.54, -0.10, p=0.004). EXPERT OPINION No double-blind evidence for altered AE burden associated with antipsychotic co-treatment was found. However, AEs were insufficiently and incompletely reported and follow-up duration was modest. Adjunctive partial D2-agonists might be beneficial for counteracting several AEs. High-quality, long-term studies that comprehensively assess AEs are needed.

Abstract
INTRODUCTION Guidelines for the treatment of psychoses recommend antipsychotic monotherapy. However, the rate of antipsychotic polytherapy has increased over the last decade, reaching up to 60% in some settings. Studies evaluating the costs and impact of antipsychotic polytherapy in the health system are scarce. OBJECTIVE To estimate the costs of antipsychotic polytherapy and its impact on public health costs in a sample of subjects with psychotic disorders living in residential facilities in the city of Sao Paulo, Brazil. METHOD A cross-sectional study that used a bottom-up approach for collecting costs data in a public health provider's perspective. Subjects with psychosis living in 20 fully-staffed residential facilities in the city of Sao Paulo were assessed for clinical and psychosocial profile, severity of symptoms, quality of life, use of health services and pharmacological treatment. The impact of polytherapy on total direct costs was evaluated. RESULTS 147 subjects were included, 134 used antipsychotics regularly and 38% were in use of antipsychotic polytherapy. There were no significant differences in clinical and psychosocial characteristics between polytherapy and monotherapy groups. Four variables explained 30% of direct costs: the number of antipsychotics, location of the residential facility, time living in the facility and use of olanzapine. The costs of antipsychotics corresponded to 94.4% of the total psychotropic costs and to 49.5% of all health services use when excluding accommodation costs. Olanzapine costs corresponded to 51% of all psychotropic costs. CONCLUSION Antipsychotic polytherapy is a huge economic burden to public health service, despite the lack of evidence supporting this practice. Great variations on antipsychotic costs explicit the need of establishing protocols for rational antipsychotic prescriptions and consequently optimising resource allocation. Cost-effectiveness studies are necessary to estimate the best value for money among antipsychotics, especially in low and middle income countries.

Abstract
BACKGROUND The objective of this study was to characterize real-world treatment patterns in the prescription of antipsychotic polypharmacy (≥ 2 concurrent antipsychotics) compared with antipsychotic monotherapy for patients with schizophrenia. METHODS This study was a retrospective claims-based analysis of patients (aged 13-64 years) with schizophrenia belonging to an employer-based health plan. Duration of therapy was measured as the number of treatment days over one year following the initial date of antipsychotic therapy. Discontinuation was defined as a 90-day gap in antipsychotic treatment (or in at least one antipsychotic for the polypharmacy group). Logistic regression analyses were used to predict discontinuation within one year. Ordinary Least Squares (OLS) regressions were used to predict duration of therapy (by type of therapy) when controlling for gender, region, number of somatic and psychiatric comorbidities, Deyo-Charlson comorbidity score, and number of psychiatric and somatic medications. RESULTS Of the 4,156 patients, 3,188 received monotherapy and 968 received polypharmacy. Mean age was 40 years (37.8 years for polypharmacy vs 40.3 years for monotherapy, p < 0.001). Within one year, 77% of the polypharmacy group and 54% of the monotherapy group discontinued treatment. The average duration of therapy was 163 [SD = 143] days in the polypharmacy group vs 253 [SD = 147] days in the monotherapy group. In both cohorts, patients <25 years had a higher frequency of discontinuations than those ≥ 26 years. Age and polypharmacy were independent predictors of treatment duration and discontinuation prior to one year. CONCLUSIONS One quarter of patients with schizophrenia received antipsychotic polypharmacy. Discontinuation was higher in the polypharmacy group. Age and polypharmacy were significant predictors of treatment discontinuation.

Abstract
BACKGROUND Antidepressant prescriptions have increased exponentially, burdening health care costs. OBJECTIVE To evaluate the costs and effects of an antidepressant cessation advice in case of inappropriate long-term use in primary care, i.e. long-term usage without a (current) indication. METHODS A economic evaluation during 1-year follow-up was performed, from a societal perspective, as part of a cluster-randomised controlled clinical trial (PANDA). Costs were assessed using the Trimbos/iMTA questionnaire for costs associated with psychiatric illness. Health-related quality of life was measured using the EuroQol 5D. Outcome was costs per quality adjusted life year (QALY). Missing values were estimated using multiple imputation, bootstrap simulations were performed to address the uncertainty surrounding the incremental cost-effectiveness ratios (ICERs). RESULTS There was no difference in average QALYs between the intervention (0.70) and control group (0.72) [difference -0.02 (95% CI -0.05 to 0.10)]. The intervention group, however, was less expensive than the control group (total costs €3636 versus €5267, respectively). Most cost-effectiveness pairs were located in the south-west quadrant of the cost-effectiveness plane, implying the intervention was less effective but also less costly. The ICER of the pooled data was €70,180, meaning that for one QALY lost, €70,180 is saved. CONCLUSIONS This study shows that an antidepressant cessation advice given to patients (and their FPs) with inappropriate long-term antidepressant usage, albeit not effective, does seem to result in a reduction of societal costs. This reduction in costs is mostly due to reduction of productivity losses, possibly due to patient empowerment and loss of stigma.

Abstract
Purpose Given the metabolic and neurologic side effects of antipsychotics and concerns about the increased risks associated with concomitant use, antipsychotic polypharmacy is a quality concern. This study assessed the operating characteristics of a Medicaid claims-based measure of antipsychotic polypharmacy. Methods A random sample from 10 public mental health clinics and 312 patients met criteria for this study. Medical record extractors were blind to measure status. We examined the prevalence, sensitivity, specificity, and positive predictive value (PPV) in Medicaid claims, testing nine different definitions of antipsychotic polypharmacy, including >14, >60, or >90 days concurrent use of ≥2 antipsychotic agents, each with allowable gaps of up to 0, 14, or 32 days in days' supply of antipsychotic medications. Results All Medicaid claims measure definitions tested had excellent specificity and PPV (>91%). Good to excellent sensitivity was dependent upon use of a 32-day gap allowance, particularly as duration of concurrent antipsychotic use increased. The proposed claims-based measure (90-day concurrent use of ≥2 or more antipsychotics, allowing for a 32-day gap) had excellent specificity (99.1%, 95%CI: 98.2-99.6) and PPV (90.9%, 95%CI: 83.1-95.7) with good sensitivity (79.4%, 95%CI: 70.4-86.6). The overall level of concordance between claims and medical record-based categorization of antipsychotic polypharmacy was high (96.4%, n = 301/312 clients, Cohen's K = 84.7, 95%CI: 75.9-93.5). Discrepant cases were reviewed, and implications are discussed. Conclusions Administrative claims data can be used to construct valid measures of antipsychotic polypharmacy.

Polypharmacy and comorbidity are associated with a lower early virologic response in hepatitis C patients treated with first generation protease inhibitor triple therapy: a preliminary analysis. Dig Dis Sci 2013; 58:3348-58.

Abstract
BACKGROUND AND AIMS The protease inhibitors (PIs) boceprevir and telaprevir are currently standard treatment as part of triple therapy regimens (TTx) for chronic HCV genotype 1 (GT1) patients. In this preliminary analysis, we have compared demographic variables, polypharmacy, and Charlson's comorbid index (CCI) with Rapid Virological Response (RVR) and extended RVR (eRVR) rates in HCV GT1 patients receiving PI containing TTx. METHODS Retrospective descriptive cohort study. RESULTS Among 74 HCV patients (46 M, 28 F; age: 54.43 ± 9.52 years; African Americans: 59.5 %) in this initial analysis, 44 % achieved RVR. All these RVR patients also achieved eRVR. Patients achieving RVR and eRVR were 50 ± 11.7 (mean ± SD) years old, compared to 58 ± 5.2 years without an RVR (p < 0.005). The average number of medications taken by patients achieving RVR and eRVR was 5 ± 2.7 compared to 9.24 ± 3.4 in patients not achieving RVR and eRVR (p < 0.005). Twenty-five percent of patients who were not on CYP3A4 inhibitors had an RVR and eRVR compared to 63.2 % who were taking CYP3A4 inhibitors (p = 0.001). Patients achieving RVR and eRVR had a lower CCI (1.61 ± 1.37) compared to those not achieving RVR and eRVR (2.8 ± 2.7; p = 0.02). Multivariate analysis also revealed a significant correlation between increased polypharmacy and CCI with lower RVR and eRVR rates. CONCLUSIONS These preliminary treatment data demonstrate that increased polypharmacy and higher degrees of comorbidity decrease RVR and eRVR rates among patients receiving first generation PI-containing TTx regimens.

Abstract
While combining antipsychotics is common in schizophrenia treatment, the literature on the reasons for antipsychotic polypharmacy (APP) is limited. We aimed to identify prescriber attitudes and rationales for APP in Japan where high APP utilization is reported. Two-hundred and seventeen psychiatrists participated in the survey, which assessed APP attitudes and behaviors. Prescribing APP to 47.7±24.7% (mean±S.D.) of their patients, psychiatrists reported that they were "moderately" concerned about APP. The most APP-justifiable factors were (1="not at all" to 5="extreme") cross titration (4.50±0.67), randomized controlled evidence (3.67±0.83), and treatment of comorbid conditions (3.31±0.83). Conversely, APP-discouraging factors were chronic side effects (4.14±0.64), difficulty determining cause and effect (4.07±0.74), and acute side effects (3.99±0.81). Comparing high to low APP prescribers (>50% vs. ≤50% of patients), no differences emerged regarding APP justification and concerns. In multivariate analyses, high APP use was associated with practice at a psychiatric hospital (OR: 2.70, 95% CI: 1.29-5.67, p=0.009), concern about potential drug-drug interactions (OR: 1.56, 95% CI: 1.04-2.35, p=0.031), and less reliance on case reports of APP showing efficacy (OR: 0.64, 95% CI: 0.44-0.92, p=0.017) (r(2)=0.111, p=0.001). High and low APP prescribers shared a comparable degree of justifications and concerns. Future research should examine the impact of cultural determinants on APP.

Abstract
OBJECTIVE The purpose of this study was to review the scientific evidence for neurobiological rationale, efficacy, tolerability and cost effectiveness of antipsychotic polypharmacy (APP). DATA SOURCES A systematic literature search of Medline, Embase, Ovid and the Cochrane Database of Systematic Reviews until April 2012 was carried out. RESULTS Theories behind APP have only modest pre-clinical and clinical evidence. We found limited statistical evidence supporting modest efficacy of APP in patients with psychotic symptoms refractory to clozapine. APP is associated with increased mortality, metabolic syndrome, decreased cognitive functioning, high dose prescription and non-adherence. It brings up extra costs, lacking evidence for cost-effectiveness. CONCLUSIONS Pre-clinical studies underpinning neurobiological hypotheses in APP are lacking. Evidence supporting efficacy of APP is limited with modest beneficial clinical relevance. APP is associated with several serious adverse effects and increased health costs. In the absence of more convincing pre-clinical support and clinical evidence we advise adherence to existing guidelines and limiting combinations of antipsychotics (in consideration with other pharmacotherapeutic, somatic and psychotherapeutic options) to patients with clozapine-refractory psychosis in well-evaluated individual trials that might need 10 weeks or more.

Abstract
Antipsychotic polypharmacy (APP) is common in the treatment of schizophrenia spectrum disorders. The literature indicates that APP is related to patient, illness, and treatment variables that are proxy measures for greater illness acuity, severity, complexity, and chronicity. The largely unknown relative risks and benefits of APP need to be weighed against the known risks and benefits of clozapine for treatment-resistant patients. To inform evidence-based clinical practice, controlled, high-quality antipsychotic combination and discontinuation trials are necessary to determine the effectiveness, safety, and role of APP in the management of severely ill patients with insufficient response to antipsychotic monotherapy.

Abstract
INTRODUCTION Antipsychotic polypharmacy (APP), the concomitant use of ≥ 2 antipsychotics, is common in clinical practice. Prior reviews have focused on the efficacy of APP, but no systematic review exists regarding the safety and tolerability of this practice. AREAS COVERED A systematic review of adverse effects associated with APP was conducted to prepare this review; case series with ≥ 2 patients, chart reviews, naturalistic, database, cohort and randomized studies that reported on the association between APP in general or specific APP combinations and global or specific adverse effect were included. Methodological limitations of available studies are discussed and recommendations for clinicians and future research are provided. EXPERT OPINION Across mostly small and uncontrolled studies, APP has been associated with increased global side effect burden, rates of Parkinsonian side effects, anticholinergic use, hyperprolactinemia, sexual dysfunction, hypersalivation, sedation/somnolence, cognitive impairment and diabetes. Effects on akathisia and mortality were inconclusive. Although some combinations, particularly aripiprazole augmentation of an agent with greater side effect burden, may reduce weight gain, dyslipidemia, hyperprolactinemia and sexual dysfunction, APP should remain a last-resort treatment option after monotherapy, switching and non-antipsychotic combinations have failed. More data are needed to further inform the individualized risk-benefit evaluation of APP.

Abstract
Antipsychotic polytherapy (APT) has evolved as a common treatment strategy at odds with recommendations from schizophrenia treatment guidelines. The literature on combinations with clozapine as a means to enhance efficacy and with aripiprazole to reduce side effects was reviewed. No solid evidence supporting antipsychotic combinations with clozapine for treatment-resistant patients with schizophrenia was identified. The reason for this may be that most combinations with clozapine increase the D(2)-receptor blockade, and this strategy is probably not efficient for patients with treatment-resistant schizophrenia. Some basic and clinical evidence for the addition of aripiprazole to lower prolactin levels was identified. In conclusion, there is very limited support in the evidence for the feasibility of rational APT.
