Abstract
BACKGROUND AND OBJECTIVES Second-generation antipsychotics (SGAs) for schizophrenia show different risk profiles, whose evidence has been evaluated through comparative reviews on randomized controlled trials (RCTs) and observational studies. METHODS We performed a systematic review and meta-analysis of weight gains, metabolic and cardiovascular side effects of SGAs, relying on both RCTs and observational studies, by comparing variations between the start of treatment and the end of follow-up. The systematic review refers to papers published from June 2009 to November 2020. PRISMA criteria were followed. No restrictions on heterogeneity level have been considered for meta-analysis. A test for the summary effect measure and heterogeneity (I2 metric) was used. RESULTS Seventy-nine papers were selected from 3076 studies (61% RCTs, 39% observational studies). Olanzapine and risperidone reported the greatest weight gain and olanzapine the largest BMI increase. Paliperidone showed the highest increase in total cholesterol, but is the only drug reporting an increase in the HDL cholesterol. Quetiapine XR showed the highest decrease in fasting glucose. Lurasidone showed the lowest increase in body weight and a reduction in BMI and was also the only treatment reporting a decrease in total cholesterol and triglycerides. The highest increase in systolic and diastolic blood pressure was reported by quetiapine XR. CONCLUSIONS Despite some limitations (differences in the mean dosages per patient and other side effects not included) this paper provides the first complete meta-analysis on SGAs in variations on metabolic risk profile between start of treatment and end of follow-up, with useful results for clinical practice and possibly for future economic evaluation studies.

Abstract
IMPORTANCE Recent meta-analyses of randomized clinical trials (RCTs) comparing clozapine with nonclozapine second-generation antipsychotics (NC-SGAs) in schizophrenia have challenged clozapine's superiority in treatment-resistant patients. However, patients in RCTs are not necessarily generalizable to those in clinical practice. OBJECTIVE To conduct a systematic review and meta-analysis to compare various outcomes of clozapine vs oral NC-SGAs in cohort studies. DATA SOURCES Systematic literature search in PubMed, PsycINFO, and CINAHL without language restriction from database inception until December 17, 2018. STUDY SELECTION Nonrandomized cohort studies reporting effectiveness and/or safety outcomes comparing clozapine with NC-SGAs in schizophrenia or schizoaffective disorder. DATA EXTRACTION AND SYNTHESIS Independent investigators assessed studies and extracted data. Using a random-effects model, the study calculated risk ratio (RR) unadjusted for covariates and follow-up duration, number needed to treat/number needed to harm (NNT/NNH) for dichotomous data, and standardized mean difference (SMD) or mean difference (MD) for continuous data. MAIN OUTCOMES AND MEASURES Coprimary outcomes were hospitalization and all-cause discontinuation. Secondary outcomes included all effectiveness and safety outcomes reported in at least 3 analyzable studies. RESULTS Of 8446 hits, 68 articles from 63 individual cohort studies (n = 109 341) (60.3% male; mean [SD] age of 38.8 [6.5] years, illness duration of 11.0 [5.1] years, and study duration of 19.1 [23.3] months) were meta-analyzed. Compared with NC-SGAs, despite greater illness severity (17 studies [n = 38 766]; Hedges g, 0.222; 95% CI, 0.013-0.430; P = .04), clozapine was significantly associated with lower hospitalization risk (19 studies [n = 49 453]; RR, 0.817; 95% CI, 0.725-0.920; P = .001; NNT, 18; 95% CI, 12-40) and all-cause discontinuation (16 studies [n = 56 368]; RR, 0.732; 95% CI, 0.639-0.838; P < .001; NNT, 8; 95% CI, 6-12). Associations were statistically significant for comparisons with quetiapine fumarate and aripiprazole regarding hospitalization and all NC-SGAs, except aripiprazole, for all-cause discontinuation. Clozapine was also significantly associated with better outcomes regarding overall symptoms (SMD, -0.302; 95% CI, -0.572 to -0.032; P = .03) and Clinical Global Impressions scale severity (SMD, -1.182; 95% CI, -2.243 to -0.122; P = .03). Clozapine was significantly associated with increases in body weight (MD, 1.70; 95% CI, 0.31-3.08 kg; P = .02), body mass index (MD, 0.96; 95% CI, 0.24-1.68; P = .009), and type 2 diabetes (RR, 1.777; 95% CI, 1.229-2.570; P = .002; NNH, 27; 95% CI, 13-90). CONCLUSIONS AND RELEVANCE In cohort studies, despite more severely ill patients being treated with clozapine, use of clozapine was associated with better key efficacy outcomes and higher cardiometabolic-related risk outcomes vs NC-SGAs.

Abstract
The study aims to identify prescribing and switching patterns of antipsychotics in clinical practice. A 16-month, prospective study was conducted at the Psychiatric Hospital Idrija, Slovenia. Inpatients (N = 311) with schizophrenia spectrum disorders were observed. The causes for switching antipsychotics and switching strategies were analyzed. Analyzing a total of 3954 prescriptions, the collected data confirmed that treatment strategies in this psychiatric hospital are very complex. It was found that 37 percent of inpatients had at least one switch. Moreover, switches that included three or more antipsychotics were detected. The most common causes for switching antipsychotics were adverse reactions and inefficacy or lack of efficacy. Among switching options, abrupt switch was recorded several times. As some patients are receiving several antipsychotics at the same time, it is possible that unusual switching occurs in clinical practice. It seems that the choice of switching strategy is also affected by the cause and urgency for switching an antipsychotic.

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

Abstract
Introduction Antipsychotics (AP) induce weight gain. However, reviews and meta-analyses generally are restricted to second generation antipsychotics (SGA) and do not stratify for duration of AP use. It is hypothesised that patients gain more weight if duration of AP use is longer. Method A meta-analysis was conducted of clinical trials of AP that reported weight change. Outcome measures were body weight change, change in BMI and clinically relevant weight change (7% weight gain or loss). Duration of AP-use was stratified as follows: ≤6 weeks, 6–16 weeks, 16–38 weeks and >38 weeks. Forest plots stratified by AP as well as by duration of use were generated and results were summarised in figures. Results 307 articles met inclusion criteria. The majority were AP switch studies. Almost all AP showed a degree of weight gain after prolonged use, except for amisulpride, aripiprazole and ziprasidone, for which prolonged exposure resulted in negligible weight change. The level of weight gain per AP varied from discrete to severe. Contrary to expectations, switch of AP did not result in weight loss for amisulpride, aripiprazole or ziprasidone. In AP-naive patients, weight gain was much more pronounced for all AP. Conclusion Given prolonged exposure, virtually all AP are associated with weight gain. The rational of switching AP to achieve weight reduction may be overrated. In AP-naive patients, weight gain is more pronounced.

Reasons and clinical outcomes of antipsychotic treatment switch in outpatients with schizophrenia in real-life clinical settings: the ETOS observational study. Ann Gen Psychiatry 2013; 12:42. [PMID: 24359635 PMCID: PMC3878189 DOI: 10.1186/1744-859x-12-42] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2013] [Accepted: 12/03/2013] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Patients under antipsychotic treatment for schizophrenia commonly exhibit poor adherence to treatment, high rates of treatment discontinuation, and frequent treatment changes. The ETOS study aimed to identify the reasons leading physicians to decide to switch antipsychotic treatment in outpatients with schizophrenia and to evaluate the outcome of this switch. METHODS ETOS was an observational 18-week (four visits) study in outpatients 18 to 65 years old, diagnosed with schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders - 4th edition criteria at least 6 months prior to enrolment, who were initiated on a new antipsychotic monotherapy treatment within the 2 weeks prior to enrollment. A total of 574 patients were recruited by 87 hospital- and office-based physicians. Ethical approval was obtained prior to study initiation (NCT00999895). RESULTS The final analysis included 568 patients, 39.0 ± 11.2 years old with mean disease duration of 11.7 years. The male-to-female ratio was 53:47. The main reason for switching antipsychotic treatment was lack of tolerability (n = 369, 65.0%), followed by lack of efficacy (n = 249, 43.8%). Following treatment switch, 87.9% of patients (n = 499) showed meaningful clinical benefit by achieving a Clinical Global Impression-Clinical Benefit score of ≤4 at the final visit. By the end of the study, total Positive and Negative Syndrome Scale, Clinical Global Impression-Improvement, Clinical Global Impression-Severity, and Simpson-Angus Scale scores demonstrated significant mean decreases of 31.69, 0.70, 1.14, and 11.30, respectively (all p < 0.0001). Treatment adherence remarkably improved. CONCLUSION In the ETOS study, switch of antipsychotic monotherapy for reasons relating to lack of efficacy and/or tolerability was associated with significantly improved clinical benefit and significant increase of patients' adherence to treatment.

Abstract
OBJECTIVE Extended release (XR) and immediate release (IR) quetiapine have differing dosing, titration and plasma concentration profiles. The authors assessed whether the use of quetiapine XR and IR in schizophrenia spectrum disorders (SCZ) and bipolar disorder (BD) differ. DESIGN Retrospective non-interventional registry study. SETTING Secondary healthcare. PARTICIPANTS All SCZ and BD (ICD-10 codes F20-F29, F30-F31) patients discharged between June 2008 and June 2010 from a Finnish psychiatric hospital with any use of quetiapine during their inpatient stay. PRIMARY AND SECONDARY OUTCOME MEASURES Differences in patient characteristics between quetiapine XR and IR users were tested. To assess the profile of XR versus IR patients, logistic regressions were performed. RESULTS 43 patients used quetiapine XR, 58 used quetiapine IR and 55 used both formulations (n=156). 102 patients were diagnosed with SCZ and 54 with BD, with no significant differences between the quetiapine formulations. The mean daily dose of quetiapine XR was significantly higher than that of quetiapine IR (542 mg vs 328 mg; p<0.001). This was also true for the SCZ subgroup (XR: 593 mg vs IR: 338 mg; p<0.001) and the BD subgroup (XR: 466 mg vs IR: 308 mg; p=0.009). 48% of all quetiapine IR patients used a mean dose of ≤200 mg compared with 2% of XR patients. Injectable antipsychotics were combined with quetiapine IR but not with quetiapine XR (12% vs 0%; p=0.019). At discharge, quetiapine XR was used as monotherapy to a greater extent than IR (79% vs 44%; p=0.003). The odds for quetiapine XR use in hospital were lower with advancing age, substance abuse diagnosis and prior IR use. CONCLUSIONS Among SCZ and BD inpatients, quetiapine XR was more often used as monotherapy and in significantly higher doses than quetiapine IR. Differential use of the quetiapine formulations appears to depend, at least in part, on patient characteristics.

Abstract
BACKGROUND To analyse the extent and profile of outpatient regular dispensation of antipsychotics, both in combination and monotherapy, in the Barcelona Health Region (Spain), focusing on the use of clozapine and long-acting injections (LAI). METHODS Antipsychotic drugs dispensed for people older than 18 and processed by the Catalan Health Service during 2007 were retrospectively reviewed. First and second generation antipsychotic drugs (FGA and SGA) from the Anatomical Therapeutic Chemical classification (ATC) code N05A (except lithium) were included. A patient selection algorithm was designed to identify prescriptions regularly dispensed. Variables included were age, gender, antipsychotic type, route of administration and number of packages dispensed. RESULTS A total of 117,811 patients were given any antipsychotic, of whom 71,004 regularly received such drugs. Among the latter, 9,855 (13.9%) corresponded to an antipsychotic combination, 47,386 (66.7%) to monotherapy and 13,763 (19.4%) to unspecified combinations. Of the patients given antipsychotics in association, 58% were men. Olanzapine (37.1%) and oral risperidone (36.4%) were the most common dispensations. Analysis of the patients dispensed two antipsychotics (57.8%) revealed 198 different combinations, the most frequent being the association of FGA and SGA (62.0%). Clozapine was dispensed to 2.3% of patients. Of those who were receiving antipsychotics in combination, 6.6% were given clozapine, being clozapine plus amisulpride the most frequent association (22.8%). A total of 3.800 patients (5.4%) were given LAI antipsychotics, and 2.662 of these (70.1%) were in combination. Risperidone was the most widely used LAI. CONCLUSIONS The scant evidence available regarding the efficacy of combining different antipsychotics contrasts with the high number and variety of combinations prescribed to outpatients, as well as with the limited use of clozapine.

Abstract
AIMS This study compared all-cause medication discontinuation (any switch, augmentation or medication discontinuation) in matched cohorts of patients with schizophrenia who were initiated on depot or oral antipsychotics. Other objectives included between-group comparisons of resource use, and clinical and functional outcomes. METHODS This post hoc analysis of a one-year, multicentre, prospective, observational study included outpatients with schizophrenia who required a change in their antipsychotic medication because of a physician-perceived risk of medication non-adherence. Patients were matched 1 : 1 using an optimal algorithm with rank-based Mahalanobis distances. All-cause medication discontinuation was compared using the Klein and Moeschberger test for survival and hazard ratios (HR) with 95% confidence intervals (CI) were calculated using a Cox proportional hazards model, stratifying on matched pairs. RESULTS Forty patients who initiated a depot antipsychotic could be matched to patients who initiated an oral antipsychotic. Fewer depot-treated patients discontinued their antipsychotic medication at least once compared with oral-treated patients [20% (8/40) vs. 40% (16/40)]. Depot-treated patients discontinued their medication later (Klein and Moeschberger test p = 0.025) and were less likely to discontinue their initial antipsychotic medication [HR = 0.33 (95% CI, 0.12-0.92), p = 0.033] than oral-treated patients. There were few differences in resource use and no differences in clinical and functional outcomes between cohorts. CONCLUSION In this matched-cohort analysis, patients with schizophrenia who were considered to be non-adherent with their prior oral antipsychotics were less likely to discontinue their medication for any cause if they were initiated on depot compared with oral antipsychotics.

Abstract
BACKGROUND This study aimed to improve physicians' understanding of the treatment circumstances and needs of outpatients with schizophrenia at risk of nonadherence, by naturalistically assessing antipsychotic treatment patterns, clinical outcomes, and health care service use in this little-studied patient population. METHODS In this one-year, prospective, multicenter, noninterventional, observational study, patients considered at risk of nonadherence by their physicians were switched from their primary oral antipsychotic to another oral or a depot antipsychotic at study entry. All cause treatment discontinuation (antipsychotic switch, augmentation, or discontinuation) during the study was assessed using Kaplan-Meier survival analyses and descriptive statistics. Patients' illness severity, quality of life, attitude towards medication, patient-reported adherence, and health care resource utilization were assessed during the study. RESULTS Of the 406 enrolled patients, 43 (10.6%) were switched to depot and 363 (89.4%) were switched to oral antipsychotics at study entry. During the study, 99 (24.4%) patients switched, augmented, or discontinued their antipsychotic (all cause treatment discontinuation). Of the 99 patients who switched, augmented, or discontinued their antipsychotic, 8 (18.6%) were taking depot and 91 (25.0%) were taking oral antipsychotics. These patients were switched to either depot (n = 15) or oral (n = 78) antipsychotics, or discontinued their antipsychotic medication (n = 6). Inadequate response was the most frequently reported reason for medication discontinuation. During the study, patients' clinical and functional status improved significantly and service use was low. Most patients considered themselves to be adherent at study entry, and this favorable self-perception increased during the study (from 68.5% to 88.1%). CONCLUSION Although identified as at risk of nonadherence, few patients in this naturalistic study discontinued their prescribed antipsychotic medication during the study. The discrepancy between the physicians' perception of their patient's medication adherence and the patients' self-perceived adherence highlights the need to better understand the underlying reasons for this phenomenon.

Abstract
BACKGROUND We tested the hypothesis that combinations and total daily doses of psychotropics for hospitalized patients diagnosed with major psychiatric disorders are rising. METHODS We evaluated McLean Hospital records of 481 consecutive inpatients with DSM-IV schizophrenia, schizoaffective, or bipolar disorders in 2004 (n = 278) or 2009 (n = 203) to compare characteristics and treatments. RESULTS In 2009, Clinical Global Impression (CGI)-severity scores were 6% lower at intake and improved 1.7 times more than in 2004, as hospitalization-length decreased by 12%. Polytherapy (> or = 2 psychotropics) increased in 2009 (affective or schizoaffective disorders > schizophrenia). Total psychotropics/patient (3.1-3.2) remained stable but mood-stabilizers/patient increased markedly and antipsychotics/patient decreased somewhat in 2009. Antipsychotic-choice (2009) ranked: quetiapine, aripiprazole, risperidone, and others; mood-stabilizers ranked: lamotrigine, valproate, lithium, and others (1/4 off-label). In 2009, final total antipsychotic doses (mg/day) increased by 97%, and mood-stabilizers by 75%. Adverse-effect rates fell by half. Factors differing independently for 2009 versus 2004 ranked: (a) more CGI improvement, (b) more mood-stabilizers/patient, (c) lower admission CGI scores, and (c) higher total antipsychotic dose. COMMENT Combinations and doses of antipsychotic and mood-stabilizing drugs for inpatients increased markedly (2004 vs. 2009) without consistent correspondence of agents/person and doses, without apparent increase in major adverse effects, and with possibly superior clinical improvement.
