Schizophrenia Treatment with Second-Generation Antipsychotics: A Multi-Country Comparison of the Costs of Cardiovascular and Metabolic Adverse Events and Weight Gain. Neuropsychiatr Dis Treat 2021; 17:125-137. [PMID: 33505160 PMCID: PMC7829121 DOI: 10.2147/ndt.s282856] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 11/18/2020] [Indexed: 12/28/2022] Open
Abstract
PURPOSE Cardiovascular and metabolic adverse events are costly to treat, and their incidence is increased amongst people with schizophrenia, with different rates observed for second-generation antipsychotics. To inform treatment choice, this study sought to estimate the lifetime costs associated with antipsychotic choice, and how these costs varied across European countries. METHODS Systematic searches were conducted to identify evidence on effectiveness and costs. A Markov model was developed to assess the costs of ten antipsychotics: aripiprazole, brexpiprazole, cariprazine, lumateperone, lurasidone, olanzapine, paliperidone, quetiapine, risperidone and ziprasidone. Costs were obtained for seven countries: Italy, Hungary, France, Slovenia, Spain, Sweden and the UK. The costs considered were adverse events (including diabetes, myocardial infarction, stroke and weight gain), drug costs, relapse, treatment discontinuation and schizophrenia management. Two adult populations were modelled; initiating either acute or maintenance treatment, with a lifetime horizon for both. RESULTS Lurasidone was associated with the lowest lifetime costs amongst patients initiating acute treatment compared to all other atypical antipsychotics considered. The second lowest costs were for ziprasidone. These results were observed for all seven countries. The main drivers of cost differences were rates of diabetes and cardiovascular diseases, which were lowest for lurasidone, followed by ziprasidone then lumateperone. Costs for managing weight gain were lowest for lurasidone and ziprasidone. Similar results were observed for patients initiating maintenance treatment. CONCLUSION Diabetes and cardiovascular events are large drivers of lifetime costs for people with schizophrenia. Lurasidone is predicted to have the lowest rates of these adverse events, and so the lowest costs amongst patients initiating acute treatment in seven European countries compared to nine other antipsychotics. Future research should investigate the individual costs of relapse management, including differences in the costs and proportions of hospitalizations.

Potential gains in life expectancy from reducing amenable mortality among people diagnosed with serious mental illness in the United Kingdom. PLoS One 2020; 15:e0230674.

Abstract
BACKGROUND To estimate the potential gain in life expectancy from addressing modifiable risk factors for all-cause mortality (excluding suicide and deaths from accidents or violence) across specific serious mental illness (SMI) subgroups, namely schizophrenia, schizoaffective disorders, and bipolar disorders in a Western population. METHODS We have used relative risks from recent meta-analyses to estimate the population attribution fraction (PAF) due to specific modifiable risk factors known to be associated with all-cause mortality within SMI. The potential gain in life expectancy at birth, age 50 and age 65 years were assessed by estimating the combined effect of modifiable risk factors from different contextual levels (behavioural, healthcare, social) and accounting for the effectiveness of existing interventions tackling these factors. Projections for annual gain in life expectancy at birth during a two-decade was estimated using the Annual Percentage Change (APC) formula. The predicted estimates were based on mortality rates for year 2014-2015. RESULTS Based on the effectiveness of existing interventions targeting these modifiable risk factors, we estimated potential gain in life expectancy at birth of four (bipolar disorders), six (schizoaffective disorders), or seven years (schizophrenia). The gain in life expectancy at age 50 years was three (bipolar disorders) or five (schizophrenia and schizoaffective disorders) years. The projected gain in life expectancy at age 65 years was three (bipolar disorders) or four (schizophrenia and schizoaffective disorders) years. CONCLUSIONS The implementation of existing interventions targeting modifiable risk factors could narrow the current mortality gap between the general and the SMI populations by 24% (men) to 28% (women). These projections represent ideal circumstances and without the limitation of overestimation which often comes with PAFs.

Abstract
OBJECTIVE Previous research shows that patients with schizophrenia have increased cardiovascular disease risk than general population. Increased cardiovascular risk in schizophrenia patients have been associated with many reasons such as antipsychotic drugs, genetic predisposition, andlifestyle. In this study, we aimed to investigate the relationship between the risk of heart disease and schizophrenia symptomatology. METHODS The 10-year cardiovascular risk was assessed by the Framingham Risk Score (FRS) in 103 patients with schizophrenia and in 39 healthy controls. Sociodemographic characteristics, age at schizophrenia onset, duration of illness, number of hospitalizations, the course of the disease and antipsychotic medications were recorded. Patients' symptoms were evaluated via The Scale for the Assessment of Negative Symptoms (SANS), The Scale for the Assessment of Positive Symptoms (SAPS), and Calgary Depression Scale for Schizophrenia (CDSS). RESULTS Ten-year cardiovascular risk was 5.16% inpatients with schizophrenia, and 3.02% in control group (p=0.030). No significant correlation was found between FRS scores, SANS, SAPS, and CDSS scores. However, FRS scores were significantly correlated with age, number of hospitalizations and duration of disease (r=0.300, 0.261, 0.252, respectively). Moreover FRS scores were higher (p=0.008) and high-density lipoprotein (HDL) levels were lower (p=0.048) in patients using multiple antipsychotics. CONCLUSION Our findings suggest a relationship between the risk of cardiovascular disease and the duration and overall severity of schizophrenia and also highlights the role of antipsychotics in this relationship.

Abstract
AIM Using routine hemoglobin A1c (HbA1c) testing to describe the prevalence, characteristics, and length of stay (LOS) of psychiatry inpatients with type 2 diabetes compared to those with pre-diabetes and those without diabetes. METHODS In this prospective observational study, all inpatients aged greater than 30 years admitted to the Austin Health Psychiatry Unit, a major tertiary hospital, affiliated with the University of Melbourne, between February 2014 and April 2015 had routine HbA1c testing as part of the Diabetes Discovery Initiative. Patients were divided into three groups: diabetes (HbA1c ≥ 6.5%, 48 mmol/mol), pre-diabetes (HbA1c 5.7-6.4%, 39-46 mmol/mol), or no diabetes (HbA1c ≤ 5.6%, 38 mmol/mol). Baseline characteristics, co-morbidities, psychiatric illnesses, and treatment were recorded. RESULTS There were a total of 335 psychiatry inpatients (median age 41 years). The most prevalent diagnoses were schizophrenia, depression, and substance abuse. Of the 335 psychiatric inpatients, 14% (n = 46) had diabetes and 19% (n = 63) had pre-diabetes, a prevalence threefold greater than in the aged matched general population. Compared to inpatients with pre-diabetes and no diabetes, those with diabetes were older and were at least twice as likely to have hypertension, obesity, and hyperlipidemia (all p ≤ 0.002). In multivariable analyses, diabetes was associated with increasing age (p = 0.02), substance abuse (p = 0.04), dyslipidaemia (p = 0.03), and aripiprazole use (p = 0.01). Patients with diabetes also had a 70% longer expected LOS (95% CI: 20-130%; p = 0.001), compared to those with pre-diabetes and no diabetes. CONCLUSION Despite relative youth, one-third of all psychiatric inpatients above the age of 30 have diabetes or pre-diabetes. Presence of diabetes in psychiatric inpatients is associated with older age, substance abuse, and longer LOS. Routine inpatient HbA1c testing provides an opportunity for early detection and optimization of diabetes care.

Abstract
Introduction: Recent trials have failed to demonstrate differences in efficacy between first generation antipsychotics (FGAs) and second generation antipsychotics (SGAs). To reduce costs, many health care systems have restricted the availability of SGAs through use of prior authorizations. Restrictions for the off-label use of SGAs and the use of dual-antipsychotic therapy have also been implemented in many health care systems. At the South Texas Veterans Health Care System (STVHCS), a restricted drug request (RDR) method has been implemented to manage costs and improve patient safety. Risperidone, due to its lower cost and equal efficacy, is the first-line option of SGAs. If one wishes to prescribe an SGA other than risperidone, an RDR is submitted and reviewed by Veterans Integrated Service Network (VISN) pharmacists. Since the introduction of these policies at the STVHCS, the impact of the RDR has not been assessed.
Rationale: The primary aim of this study was to determine the effects of the RDR policy on the care of STVHCS veterans as evidenced by changes in hospitalization rates of veterans with a denied request for an SGA due to initial criterion failure. Secondary outcomes included: impact of antipsychotic RDR denial on mental health as evidenced by changes in no-shows and cancellations for follow-up psychiatric appointments, psychiatric emergency department visits, presence of suicidal ideation, change in weight, hemoglobin A1c, number of psychotropic medications prescribed, and extrapyramidal symptoms.
Methods: A retrospective chart review of veterans denied an initial SGA request was conducted from 3 months prior to denial to 3 months post request denial (index date). Data collected included: patient demographics, indication for SGA request, reason for SGA denial, length of time for request evaluation, number of psychiatric hospitalizations, number of no-shows and cancellations for mental health appointments, number of psychiatric emergency department visits, number of reports of suicidal ideation or attempts, weight, hemoglobin A1c lab results, presence of extrapyramidal symptoms, and number of prescribed psychotropic medications. The health care utilization data collected pre- and post-index date, were compared. Results were analyzed using Fisher's Exact, 2-tailed standardized t-tests, and descriptive statistics appropriately matched to data type.
Results: Results for both primary and secondary outcomes were not statistically significant. No differences were found in the number of veterans hospitalized pre- versus post-index date [0/33 (0%) versus 2/33 (6%), p=0.492.] The most requested indication for an SGA was PTSD [22/33 (66.7%)] and the most frequently denied SGA was quetiapine [16/33 (48.5%)].
Conclusions: Although outcomes were not statistically significant, several valuable conclusions were drawn from this research. Positive outcomes from a RDR policy were seen by the limitations placed on inappropriate medication prescribing. Also, it was observed that the number of approvals for SGAs was almost three times higher than denials. A subsequent finding from this research is the apparent lack of metabolic monitoring for veterans prescribed SGAs. Further research on these observations, as well as conducting a pharmacoeconomic analysis on the RDR policy, would also be beneficial information for health care providers.

Abstract
UNLABELLED BACKGROUND & HYPOTHESIS: Schizophrenia is associated with increased mortality rates, which has been attributed to the greater incidence of cardiovascular disease (CVD) events. The Framingham risk score (FRS) is a widely-used age- and gender-specific algorithm to estimate 10-year CVD risk and vascular age. The main aim of this study was to determine the cardiovascular risk profile in schizophrenia and examine the effect of metabolic syndrome (MetS) as a predictor of CVD risk. We hypothesized that patients with schizophrenia have an increased 10-year CVD risk. METHODS 83 Chinese patients with schizophrenia and 243 Chinese community controls were recruited. Their medical and smoking histories were obtained, and anthropometric parameters measured. All subjects provided fasted venous blood samples for lipid and glucose measurements. 10-year CVD risk and the difference between vascular and actual age (VAdiff) for each participant were computed using the FRS and compared between patients and controls. RESULTS Schizophrenia patients had a higher mean 10-year CVD risk of 4.6%, as compared with 3.1% in controls, and a greater VAdiff of 4.6 years vs. 0.6 years. Both smoking and MetS contributed significantly to the 10-year CVD risk in patients with schizophrenia, with smoking having a greater effect than MetS on this risk. CONCLUSION This study found a significantly elevated mean 10-year CVD risk and VAdiff in patients with schizophrenia compared with controls. Findings point towards the importance of smoking cessation and screening for MetS to decrease the excess CVD risk in patients with schizophrenia.

Abstract
Aim. The purpose of this retrospective study was to evaluate changes in clinical indicators which influence the quality of life (QOL) of patients with schizophrenia treated by antipsychotic therapy before and after switching to aripiprazole. Methods. A retrospective chart review of 27 patients diagnosed with schizophrenia and who were switched from one antipsychotic to aripiprazole was performed. Clinical indicators about the daily dosage of antipsychotics and antiparkinsonian drugs, psychiatric condition, and glucose/lipid metabolism, clinical evaluation by nursing observation were used to measure the responsiveness of subjects to aripiprazole. Results. Of the 27 subjects, 14 responded to the switch to aripiprazole with significant improvement of the Brief Psychiatric Rating Scale (BPRS) score (P = 0.04), significant decrease in dosage of antipsychotics in 71% of patients (P = 0.03), and tendency toward reduction in dosage of antiparkinsonian drugs (P = 0.07) and body mass index (BMI) (P = 0.06). However, 8 of 27 subjects had a significant increase in lipid levels after switching to aripiprazole (P = 0.01). Conclusion. QOL for subjects who responded to the switch to aripiprazole improved as indicated by lower doses of antipsychotic and antiparkinson medications, improvement in BPRS score, and a decrease in BMI. Results indicate little influence on patient's QOL.

Abstract
Mortality rate is high in psychiatric patients versus general population. An important cause of this increased mortality is sudden cardiac death (SCD) as a major side-effect of psychotropic drugs. These SCDs generally result from arrhythmias occurring when the posology is high and may attain a toxic threshold but also at dosages within therapeutic range, in the presence of risk factors. There are three kinds of risk factors: physiological (e.g., low cardiac rate of sportsmen), physiopathological (e.g., hepatic insufficiency, hypothyroidism) and "therapeutic" (due to interactions between psychotropic drugs and other medicines). Association of pharmacological agents may increase the likelihood of SCDs either by (i) a pharmacokinetic mechanism (e.g., increased torsadogenic potential of a psychotropic drug when its destruction and/or elimination are compromised) or (ii) a pharmacodynamical mechanism (e.g., mutual potentiation of proarrhythmic properties of two drugs). In addition, some psychotropic drugs may induce sudden death in cases of pre-existing congenital cardiopathies such as (i) congenital long QT syndrome, predisposing to torsade de pointes that eventually cause syncope and sudden death. (ii) A Brugada syndrome, that may directly cause ventricular fibrillation due to reduced sodium current through Nav1.5 channels. Moreover, psychotropic drugs may be a direct cause of cardiac lesions also leading to SCD. This is the case, for example, of phenothiazines responsible for ischemic coronaropathies and of clozapine that is involved in the occurrence of myocarditis. The aims of this work are to delineate: (i) the risk of SCD related to the use of psychotropic drugs; (ii) mechanisms involved in the occurrence of such SCD; (iii) preventive actions of psychotropic drugs side effects, on the basis of the knowledge of patient-specific risk factors, documented from clinical history, ionic balance, and ECG investigation by the psychiatrist.

Abstract
Oral aripiprazole (Abilify®) is an atypical antipsychotic agent that is approved worldwide for use in adult patients with schizophrenia. It is a quinolinone derivative that has a unique receptor binding profile as it exhibits both partial agonist activity at dopamine D(2) receptors and serotonin 5-HT(1A) receptors and antagonist activity at 5-HT(2A) receptors. In several well designed, randomized, clinical trials of 4-6 weeks duration, aripiprazole provided symptomatic control for patients with acute, relapsing schizophrenia or schizoaffective disorder. Furthermore, following 26 weeks' treatment, the time to relapse was significantly longer for patients with chronic, stabilized schizophrenia receiving aripiprazole compared with those receiving placebo. Using a variety of efficacy outcomes, aripiprazole showed a mixed response when evaluated against other antipsychotic agents in randomized clinical trials. Longer-term data showed that improvements in remission rates and response rates favoured aripiprazole over haloperidol, although, the time to failure to maintain a response was not significantly different between the treatment arms. On the other hand, improvements in positive and negative symptom scores mostly favoured olanzapine over aripiprazole, although, the time to all-cause treatment discontinuation was not significantly different between the two treatments. Several open-label, switching trials showed that aripiprazole provided continued control of symptoms in patients with schizophrenia or schizoaffective disorder. Using a variety of efficacy outcomes or quality-of-life scores, longer-term treatment generally favoured patients switched to receive aripiprazole compared with standard-of-care oral antipsychotics. Aripiprazole was generally well tolerated in patients with schizophrenia. In particular, its use seems to be associated with a lower incidence of extrapyramidal symptoms than haloperidol and fewer weight-gain issues than olanzapine. Aripiprazole also showed a favourable cardiovascular tolerability profile and its use was associated with a reduced risk of metabolic syndrome than placebo or olanzapine. As a consequence, aripiprazole may provide a more cost-effective treatment option compared with other atypical antipsychotics. In conclusion, oral aripiprazole provides an effective and well tolerated treatment alternative for the acute and long-term management of patients with schizophrenia.

Abstract
Health service providers increasingly need to consider not only the efficacy and safety of a therapy, but also its cost. Our hypothesis was that in our previously reported aripiprazole add-on or switching study, the improved outcomes would be associated with reduced costs. We here report data from this study, now to 52-week follow-up, with 27 total recruits (outpatients partially refractory or intolerant of their current antipsychotic regime). Serial clinical ratings included the Quality of Life Scale and Client Service Receipt Inventory, applied at baseline (N = 24), week 26 (N = 21) and 52 (N = 18). Cost data were unavailable for the drop outs. On last observation carried forward (LOCF) analysis, there was a significant increase in the Quality of Life Scale between baseline and one year (p = 0.007). There were also reductions over time in total direct and indirect costs. For study completers, the total costs at the one-year follow-up period were £ 482 less than those for the corresponding baseline period, with the Quality of Life Scale score at one year being 21.6 points (or 16.4 on LOCF analysis) higher. Therefore, in the completers, improved outcome was associated with reduced costs. Cost-effectiveness could be similarly investigated in a controlled trial.

The prevalence and clinical correlates of metabolic syndrome in patients with schizophrenia: findings from a cohort in Turkey. Eur Arch Psychiatry Clin Neurosci 2011; 261:69-78. [PMID: 20517698 DOI: 10.1007/s00406-010-0118-x] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2010] [Accepted: 05/12/2010] [Indexed: 10/19/2022]
Abstract
Most studies point to an increased prevalence of metabolic syndrome (MS) and an increased risk of coronary heart disease (CHD) in schizophrenia patients with MS. The aims of this study were to compare the prevalence of MS in schizophrenia patients with the general population, to explore the clinical correlates and predictors of MS and to evaluate the risk for CHD within 10 years. Consecutive 319 patients, aged 18-75 years, with a diagnosis of schizophrenia according to the DSM-IV were enrolled. The ATP-III, the ATP-IIIA and the IDF criteria were used to define MS. 10-year risk of CHD events was calculated with the Framingham score. One hundred nine (34.2%) patients met the ATP-III criteria, 118 (37%) the ATP-IIIA and 133 (41.7%) the IDF criteria for MS. Patients with MS were older, had a later onset of illness and an older age at first hospitalization. The prevalence of MS in schizophrenia patients was higher from the general population only within the 20-29 age group. Patients with MS had a higher age and sex-corrected 10-year risk of CHD events. The only predictor of MS was the age of illness onset. In conclusion, countries where the general population prevalence of MS is already too high, schizophrenia patients younger than 30 years of age might be under higher risk of morbidity and mortality related with MS. This study points to the necessity for aggressive interventions to correct MS in schizophrenia as early as possible, within the first 10 years of post detection.
