KardiaMobile 6L for measuring QT interval in people having antipsychotic medication to inform early value assessment: a systematic review.

Background: The indication for this assessment is the use of the KardiaMobile six-lead electrocardiogram device for the assessment of QT interval-based cardiac risk in service users prior to the initiation of, or for the monitoring of, antipsychotic medications, which are associated with an established risk of QT interval prolongation. Objectives: To provide an early value assessment of whether KardiaMobile six-lead has the potential to provide an effective and safe alternative to 12-lead electrocardiogram for initial assessment and monitoring of QT interval-based cardiac risk in people taking antipsychotic medications. Review methods: Twenty-seven databases were searched to April/May 2022. Review methods followed published guidelines. Where appropriate, study quality was assessed using appropriate risk of bias tools. Results were summarised by research question; accuracy/technical performance; clinical effects (on cardiac and psychiatric outcomes); service user acceptability/satisfaction; costs of KardiaMobile six-lead. Results: We did not identify any studies which provided information about the diagnostic accuracy of KardiaMobile six-lead, for the detection of corrected QT-interval prolongation, in any population. All studies which reported information about agreement between QT interval measurements (corrected and/or uncorrected) with KardiaMobile six-lead versus 12-lead electrocardiogram were conducted in non-psychiatric populations, used cardiologists and/or multiple readers to interpret electrocardiograms. Where reported or calculable, the mean difference in corrected QT interval between devices (12-lead electrocardiogram vs. KardiaMobile six-lead) was generally small (≤ 10 ms) and corrected QT interval measured using KardiaMobile six-lead was consistently lower than that measured using 12-lead electrocardiogram. All information about the use of KardiaMobile six-lead, in the context of QT interval-based cardiac risk assessment for service users who require antipsychotic medication, was taken from retrospective surveys of staff and service users who had chosen to use KardiaMobile six-lead during pilots, described in two unpublished project reports. It is important to note that both these project reports relate to pilot studies which were not intended to be used in wider evaluations of KardiaMobile six-lead for use in the NHS. Both reports included survey results which indicated that the use of KardiaMobile six-lead may be associated with reductions in the time taken to complete an electrocardiogram and costs, relative to 12-lead electrocardiogram, and that KardiaMobile six-lead was preferred over 12-lead electrocardiogram by almost all responding staff and service users. Limitations: There was a lack of published evidence about the efficacy of KardiaMobile six-lead for initial assessment and monitoring of QT interval-based cardiac risk in people taking antipsychotic medications. Conclusions: There is insufficient evidence to support a full diagnostic assessment evaluating the clinical and cost effectiveness of KardiaMobile six-lead, in the context of QT interval-based cardiac risk assessment for service users who require antipsychotic medication. The evidence to inform the aims of this early value assessment (i.e. to assess whether the device has the potential to be clinically effective and cost-effective) was also limited. This report includes a comprehensive list of research recommendations, both to reduce the uncertainty around this early value assessment and to provide the additional data needed to inform a full diagnostic assessment, including cost-effectiveness modelling.

Some medicines used for people with certain mental health problems can increase the risk of developing serious heart conditions. Although these heart conditions are rare, it is generally recommended that people have an electrocardiogram examination before starting to take these medicines. People who need to continue these medications over a period of time may need additional electrocardiograms every so often, to check for any heart problems that have developed recently. KardiaMobile six-lead (or 6-lead) is a portable electrocardiogram that may offer a less intrusive way to take electrocardiogram measurements. This is because less undressing is needed as the electrodes are only applied to fingers of the left and right hand and the left ankle or knee and the cold gel is not needed. Testing using the KardiaMobile six-lead device can be carried out at the patient's home. These features might mean that the KardiaMobile six-lead device could be more acceptable than the 12-lead electrocardiogram to some patients. This assessment considered whether the KardiaMobile six-lead device has the potential to provide an effective and safe alternative to 12-lead electrocardiogram for initial assessment and monitoring of the risk of heart problems in people taking antipsychotic medications. Based on the available evidence, it remains unclear whether KardiaMobile six-lead has adequately demonstrated sufficient evidence of potential advantage(s) over current practice to justify further research to inform assessment of its clinical effectiveness and cost effectiveness. Our report provides detailed recommendations about the research needed, to provide further information about potential benefits so that a decision can be made about whether it should be used in the NHS in England, after further research has been completed.

Management of antipsychotics in primary care: Insights from healthcare professionals and policy makers in the United Kingdom.

INTRODUCTION: Antipsychotic medication is increasingly prescribed to patients with serious mental illness. Patients with serious mental illness often have cardiovascular and metabolic comorbidities, and antipsychotics independently increase the risk of cardiometabolic disease. Despite this, many patients prescribed antipsychotics are discharged to primary care without planned psychiatric review. We explore perceptions of healthcare professionals and managers/directors of policy regarding reasons for increasing prevalence and management of antipsychotics in primary care. METHODS: Qualitative study using semi-structured interviews with 11 general practitioners (GPs), 8 psychiatrists, and 11 managers/directors of policy in the United Kingdom. Data was analysed using thematic analysis. RESULTS: Respondents reported competency gaps that impaired ability to manage patients prescribed antipsychotic medications, arising from inadequate postgraduate training and professional development. GPs lacked confidence to manage antipsychotic medications alone; psychiatrists lacked skills to address cardiometabolic risks and did not perceive this as their role. Communication barriers, lack of integrated care records, limited psychology provision, lowered expectation towards patients with serious mental illness by professionals, and pressure to discharge from hospital resulted in patients in primary care becoming 'trapped' on antipsychotics, inhibiting opportunities to deprescribe. Organisational and contractual barriers between services exacerbate this risk, with socioeconomic deprivation and lack of access to non-pharmacological interventions driving overprescribing. Professionals voiced fears of censure if a catastrophic event occurred after stopping an antipsychotic. Facilitators to overcome these barriers were suggested. CONCLUSIONS: People prescribed antipsychotics experience a fragmented health system and suboptimal care. Several interventions could be taken to improve care for this population, but inadequate availability of non-pharmacological interventions and socioeconomic factors increasing mental distress need policy change to improve outcomes. The role of professionals' fear of medicolegal or regulatory censure inhibiting antipsychotic deprescribing was a new finding in this study.

Assessment and management of delirium in a tertiary hospital-Improvements in cognitive screening and use of non-pharmacological strategies with a multidisciplinary approach.

OBJECTIVE: This series of audits aimed to determine current best practice in delirium management in a tertiary teaching hospital and to identify strategies to improve the quality of care in delirium with a focus on prevention. METHODS: We completed a series of audits following the formation of the Cognitive Impairment Reference Group, a multidisciplinary team that was created to implement delirium management guidelines and monitor compliance. Audit 1 focused on antipsychotic use in patients aged 66 years and older. Audit 2 reviewed delirium care in the Acute Medical Ward. Audit 3 included ethnographic data and investigated the use of non-pharmacological methods to prevent and manage delirium in the Geriatric Ward. Two years on, Audit 4 is a repeat of Audit 1. RESULTS: There were improved rates of cognitive screening between Audits 2 and 3 from 65% n = 40 to 86% n = 102, respectively. Most patients had one form of non-pharmacological strategy in place to prevent delirium however few had a multicomponent approach. Fewer patients were prescribed benzodiazepines alongside antipsychotics 28.57% n = 35 in Audit 1 compared to Audit 4 12.5% n = 32. CONCLUSIONS: Improved quality of care in delirium management is achievable via a co-ordinated multidisciplinary approach. These audits demonstrated improvements in both rates of cognitive screening, and use of non-pharmacological strategies prior to antipsychotic medication use and better adherence to guidelines for antipsychotic prescribing. Areas for further development in delirium prevention include the uptake of screening and individualised non-pharmacological strategies.

A systematic review of the real-world effectiveness and economic and humanistic outcomes of selected oral antipsychotics among patients with schizophrenia in the United States: Updating the evidence and gaps.

BACKGROUND: Schizophrenia is a chronic, relapsing, and burdensome psychiatric disorder affecting approximately 0.25%-0.6% of the US population. Oral antipsychotic treatment (OAT) remains the cornerstone for managing schizophrenia. However, nonadherence and high treatment failure lead to increased disease burden and medical spending. Cost-effective management of schizophrenia requires understanding the value of current therapies to facilitate better planning of management policies while addressing unmet needs. OBJECTIVE: To review existing evidence and gaps regarding real-world effectiveness and economic and humanistic outcomes of OATs, including asenapine, brexpiprazole, cariprazine, iloperidone, lumateperone, lurasidone, olanzapine/samidorphan, paliperidone, and quetiapine. METHODS: We conducted a literature search using PubMed, American Psychological Association PsycINFO (EBSCOhost), and the Cumulative Index of Nursing and Allied Health Literature from January 2010 to March 2022 as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English-language articles describing adults with schizophrenia receiving at least 1 of the selected OATs and reporting real-world effectiveness, direct or indirect costs, humanistic outcomes, behavioral outcomes, adherence/persistence patterns, or product switching were identified. RESULTS: We identified 25 studies from a total of 24,190 articles. Real-world effectiveness, cost, and adherence/persistence outcomes were reported for most OATs that were selected. Humanistic outcomes and product switching were reported only for lurasidone. Behavioral outcomes (eg, interpersonal relations and suicide ideation) were not reported for any OAT. The key economic outcomes across studies were incremental cost-effectiveness ratios, cost per quality-adjusted life-years, and health care costs. In studies that compared long-acting injectables (LAIs) with OATs, LAIs had a higher pharmacy and lower medical costs, while total health care cost was similar between LAIs and OATs. Indirect costs associated with presenteeism, absenteeism, or work productivity were not reported for any of the selected OATs. Overall, patients had poor adherence to OATs, ranging between 20% and 61% across studies. Product switching did not impact the all-cause health care costs before and after treatment. CONCLUSIONS: Our findings showed considerable gaps exist for evidence on behavioral outcomes, humanistic outcomes, medication switching, and adherence/persistence across OATs. Our findings also suggest an unmet need regarding treatment nonadherence and lack of persistence among patients receiving OATs. We identified a need for research addressing OATs' behavioral and humanistic outcomes and evaluating the impact of product switching in adults with schizophrenia in the United States, which could assist clinicians in promoting patient-centered care and help payers understand the total value of new antipsychotic drugs.

General practice pharmacist-led antipsychotic physical health monitoring: a prospective intervention scoping study.

BACKGROUND: People with severe mental health illness die prematurely, often due to preventable cardiometabolic disease, which can be exacerbated by antipsychotic medicines that are effective for treating mental illness. Literature demonstrates that physical health monitoring, as recommended in guidelines, for people receiving antipsychotics is substandard. Therefore, we aimed to scope the potential of a general practice clinical pharmacist (GPCP)-led multidisciplinary intervention optimising adherence to cardiometabolic monitoring guidelines and delivering polypharmacy reviews. METHOD: Prospective intervention scoping study in three urban general practices; one usual care, two intervention. Patients 18-65 years old prescribed oral antipsychotics were identified from records, and invited for cardiometabolic monitoring and GPCP medication review, from January to December 2022. Interventions and onward referrals were recorded and collated. Anonymised pre- and post-review data were analysed, and actions were graded for clinical importance. RESULTS: In total 1.5% (210/14,159) of patients aged 18-65 years met inclusion criteria; usual care practice (n = 58); and intervention practices (n = 152). From baseline, the usual care practice achieved an absolute 7% increase in the cardiometabolic monitoring care bundle (glucose/glycosylated haemoglobin, lipids, blood pressure plus body mass index) versus 19-58% in the intervention practices. Two-thirds (92/152) of patients participated in medication reviews, requiring pharmacological and/or non-pharmacological clinical actions. The majority of actions were graded as moderate importance. Seven percentage of patients were identified as new pre-diabetic/diabetic and 6% were at high risk of cardiovascular disease requiring statin initiation. CONCLUSION: A pharmacist-led multidisciplinary general practice-based approach may be effective at optimising cardiometabolic monitoring; identifying and treating diabetic and cardiovascular risk factors.

People with severe mental illness die 15­20 years earlier than the general population, many due to preventable and/or treatable heart disease. While antipsychotic medicines are effective for treating mental illness they are associated with potential adverse effects; weight gain, increased blood pressure, blood sugar, and cholesterol. Therefore, guidelines advise regular physical health checks for people with severe mental illness, and those receiving antipsychotics, to reduce avoidable harms and optimise preventative treatments. However, routine monitoring is substandard. This study aimed to explore the potential of a general practice pharmacist-led intervention to optimise physical health monitoring and medication reviews, from January to December 2022. Three practices participated; one providing usual care, and two the pharmacist intervention. The usual care practice achieved a 7% increase in all monitoring parameters (weight, blood pressure, blood sugars plus cholesterol), whereas the pharmacist-led practices achieved a 19­58% increase in monitoring. Two in three patients (92/152) participated in a medication review with the pharmacists that addressed a range of mental and physical health issues. Of the 152 patients in the intervention practices 6% were identified as being at high risk of heart disease requiring preventative medicines, and 7% were identified as having new diabetes and/or pre-diabetes.

A real-world assessment of healthcare costs associated with agitation in Alzheimer's dementia.

AIMS: To describe and compare clinical characteristics, healthcare costs, and institutionalization/mortality outcomes among patients with and without agitation associated with Alzheimer's dementia (AAD). METHODS: Data from the Reliant Medical Group database (01/01/2016-03/31/2020) were used, including claims, electronic medical records, and clinical information/physician notes abstracted from medical charts. Patients aged ≥55 years with Alzheimer's dementia (AD) were observed during a randomly selected 12-month study period after AD diagnosis. Using information recorded in medical charts, patients were classified into cohorts based on experiencing (agitation cohort) and not experiencing (no agitation cohort) agitated behaviours during the study period. Entropy balancing was used to create reweighted cohorts with similar characteristics. Study outcomes (patient demographic and clinical characteristics, treatments received, healthcare costs, institutionalization and death events) were compared between cohorts; agitation characteristics were described for the agitation cohort only. RESULTS: Among 711 patients included in the study, 240 were classified in the agitation cohort and 471 in the no agitation cohort. After reweighting, several comorbidities were more frequently observed in the agitation versus no agitation cohort, including infection, depression, and altered mental status. Use of antidepressants, anticonvulsants, antipsychotics, and antianxiety medications was more common in the agitation versus no agitation cohort. Common agitated behaviours included hitting (20.8%), pacing/aimless wandering (17.5%), and cursing/verbal aggression (15.0%). Total all-cause healthcare costs were $4287 per-patient-per-year higher in the agitation cohort versus no agitation cohort (p = 0.04), driven by higher inpatient costs. Death was more common and time to death and institutionalization were shorter in the agitation versus no agitation cohort. LIMITATIONS: Results may not be generalizable to the US population with AD. CONCLUSIONS: Among patients with AD, agitation was associated with shorter time to death/institutionalization and increased comorbidities, medication use, and healthcare costs, highlighting the additional clinical and economic burden that agitation poses to patients and the healthcare system.

One-Year Medication Treatment Patterns, Healthcare Resource Utilization, and Expenditures for Medicaid Patients with Schizophrenia Starting Oral Atypical Antipsychotic Medication.

Oral atypical antipsychotic (OAAP) medications are the most commonly prescribed treatment for the management of schizophrenia symptoms. This retrospective study, using Medicaid claims data (2016-2020), followed patients for 12 months after initiating OAAP therapy. Study outcomes included OAAP adherence, switching, augmentation, healthcare resource utilization (HRU), and expenditures. All-cause and schizophrenia-related HRU and expenditures were compared between adherent and nonadherent cohorts. Among 13,007 included patients (39.1 ± 12.8 years of age, 57.0% male, 36.1% Black, 31.8% White, 9.7% Hispanic), 25.7% were adherent to OAAPs (proportion of days covered [PDC] ≥ 0.8). During the 1-year follow-up period, Black individuals were in possession of an OAAP for an average of 166 days compared to 198 and 202 days for White and Hispanic patients, respectively. Approximately 16% of patients switched OAAP medications and 3.2% augmented therapy with an OAAP added to their index medication. Nearly 40% of patients were hospitalized during follow-up and 68.4% had emergency department (ED) visits. A greater proportion of nonadherent patients had all-cause inpatient (41.7% vs. 34.1%, p < 0.001) and ED visits (71.7% vs. 58.8%, p < 0.001) compared to adherent patients. Annual total healthcare expenditures were $21,020 per patient; $3481 higher for adherent versus nonadherent patients. Inpatient expenditures comprised 44.6% and 30.6% of total expenditures for nonadherent and adherent patients, respectively. Hospitalized patients' total expenditures were $23,261 higher compared to those without a hospitalization. Adherence to OAAP medication is suboptimal and associated with increased utilization of costly hospital and ED resources. Efforts to improve therapies and increase medication adherence could improve clinical and economic outcomes among individuals with schizophrenia.

Risk of long-term care admissions among Medicare beneficiaries treated with pimavanserin or quetiapine for Parkinson's disease psychosis in USA: a retrospective administrative claims database analysis.

Aim: Risk of long-term care (LTC) admission (LTCA) associated with atypical antipsychotic (AAP) use among patients with Parkinson's disease psychosis (PDP) is a major concern. However, no comparative studies have examined the differences in risk of LTC admissions between pimavanserin (PIM), the only FDA-approved AAP for PDP, and other off-label AAPs including quetiapine (QUE). Objective: To examine all-cause LTCA rates and risk among PDP patients treated with AAPs such as QUE or PIM. Methods: Analysis of Parts A, B and D claims (100% Medicare sample; 2013-2019) of Medicare beneficiaries with PDP that initiate ≥12-month continuous PIM or QUE monotherapy from 1 January 2014 to 31 December 2018 (i.e., index date) without any AAP use in the 12-month pre-index period was conducted. Outcome assessments among 1:1 propensity score-matched (31 variables - age, sex, race, region and 27 Elixhauser comorbidities) beneficiaries on PIM versus QUE included risk of all-cause skilled nursing facility stays (SNF-stays), LTC-stays, and overall LTCA (i.e., SNF-stays or LTC-stays). All-cause LTCA rates and LTCA risk were compared using logistic regression and cox proportional hazards models, respectively, controlling for demographics, comorbidities and co-existing-dementia or insomnia. Results: Of the matched sample (n = 842 for each group) from total sample (n = 9652), overall all-cause LTCA and SNF-stay rates were 23.2 and 20.2% for PIM versus 33.8 and 31.4% for QUE, respectively (p < 0.05, for each). Hazard ratio (95% CI) for risk of SNF-stay and overall LTCA was 0.78 (0.61, 0.98) and 0.80 (0.66, 0.97), respectively, for PIM versus QUE beneficiaries (p < 0.05, for each). Conclusion: The 20% lower risk of LTCA (i.e., greater delay) with PIM versus QUE in this analysis may suggest that PIM should be started early for the treatment of PDP.

Knowledge and dispensing practice of community pharmacists towards antipsychotic medicines in a Nigerian metropolitan city - a cross-sectional study.

BACKGROUND: Antipsychotic drugs are prescription-only-medications which require valid prescriptions before it can be obtained from a pharmacy. On the other hand, community pharmacists in developing countries have sometimes been implicated in over-the-counter dispensing of prescription-only-medications. OBJECTIVE: This study investigated the accessibility of antipsychotic drugs without prescriptions from community pharmacies, and the factors responsible for the over-the-counter dispensing of antipsychotics by community pharmacists. METHODS: An exploratory cross-sectional mixed method survey design using pretested structured questionnaires among 119 community pharmacists, simulated patients in 119 community pharmacies, and one-on-one in-depth interview among eleven (11) community pharmacist-owners/superintendent pharmacists were utilized for data collection. The knowledge of the pharmacists on antipsychotics including classification, side effects, and dispensing practices were explored. Qualitative data was analyzed with thematic analysis, while quantitative data was analyzed using descriptive statistics. RESULTS: Majority of the community pharmacists (87.4%) showed good knowledge of antipsychotics as it relates to the different classes and the side effects peculiar to each class. Antipsychotic medications were dispensed by 85 (71.4%) of community pharmacists without a prescription. One-on-one in-depth interview sessions with community pharmacist owners/superintendent pharmacists demonstrated that community pharmacists are knowledgeable about antipsychotics and their side effects. Reasons given for dispensing this class of drugs without prescription included emergencies, and knowledge of the person as being on the drugs long-term. About 4% pharmacists were adamant on dispensing only with prescription. CONCLUSION: Community pharmacists in Ibadan metropolis readily dispense antipsychotics without valid prescriptions despite having an optimal knowledge about the negative implications of doing so. This could be due to weak legislation and regulation of drug laws. There is a need for more stringent regulations as well as adequate sensitization about the negative effects of inappropriate dispensing of prescription-only-medications.

Assessment of psychotropic medications prescribing pattern in Gebretsadik Shawo General Hospital, South West Ethiopia.

Introduction: due to the widespread prescription of antipsychotic medications, their usage is cumulative. Evidence on the trends of medication use in Ethiopia and other parts of the world is lacking. The scant information on prescription trends and medication usage suggests that drug use is generally not sensible in both industrialized and emerging nations. So, the aim of this study was to assess the psychotropic medications prescribing pattern in Gebretsadik Shawo General Hospital, South West Ethiopia. Methods: from June 1st to July 31st, 2019, a cross-sectional study on prescriptions for psychiatric drugs was conducted at Gebretsadik Shawo General Hospital. Using systematic random sampling, prescription records were obtained from the pharmacy dispensing book. Version 21 of the statistical program for social science was used to code and analyze the data. Results: the study included 355 prescription records containing psychotropic drugs in total. The bulk of those taking the psychotropic medication were aged 20 to 49. The most often administered classes of drugs remained antipsychotic, followed by tricyclic antidepressants, antiepileptics, anxiolytics/sedatives, anticholinergic and selective serotonin reuptake inhibitors. The most often ordered antipsychotic medication, which included 102 (23.18%) medications, was chlorpromazine. Tricyclic antidepressants, which included 56 medicines (12.73%) and 24 medications (5.45%), included amitriptyline and imipramine. Conclusion: the results of this investigation showed that psychiatrists preferred traditional psychotropic medications, such as Antipsychotic tricyclic, antidepressants (TCAs) and phenothiazines, in high amounts possibly because these medications were readily available in this hospital and their prices suited patients' needs. Health care workers' interdisciplinary relationships and coherence would improve for the benefit of patients and services of higher quality.

Use of Telemedicine and Quality of Care Among Medicare Enrollees With Serious Mental Illness.

Importance: During the COVID-19 pandemic, a large fraction of mental health care was provided via telemedicine. The implications of this shift in care for use of mental health service and quality of care have not been characterized. Objective: To compare changes in care patterns and quality during the first year of the pandemic among Medicare beneficiaries with serious mental illness (schizophrenia or bipolar I disorder) cared for at practices with higher vs lower telemedicine use. Design, Setting, and Participants: In this cohort study, Medicare fee-for-service beneficiaries with schizophrenia or bipolar I disorder were attributed to specialty mental health practices that delivered the majority of their mental health care in 2019. Practices were categorized into 3 groups based on the proportion of telemental health visits provided during the first year of the pandemic (March 2020-February 2021): lowest use (0%-49%), middle use (50%-89%), or highest use (90%-100%). Across the 3 groups of practices, differential changes in patient outcomes were calculated from the year before the pandemic started to the year after. These changes were also compared with differential changes from a 2-year prepandemic period. Analyses were conducted in November 2022. Exposure: Practice-level use of telemedicine during the first year of the COVID-19 pandemic. Main Outcomes and Measures: The primary outcome was the total number of mental health visits (telemedicine plus in-person) per person. Secondary outcomes included the number of acute hospital and emergency department encounters, all-cause mortality, and quality outcomes, including adherence to antipsychotic and mood-stabilizing medications (as measured by the number of months of medication fills) and 7- and 30-day outpatient follow-up rates after discharge for a mental health hospitalization. Results: The pandemic cohort included 120 050 Medicare beneficiaries (mean [SD] age, 56.5 [14.5] years; 66 638 females [55.5%]) with serious mental illness. Compared with prepandemic changes and relative to patients receiving care at practices with the lowest telemedicine use: patients receiving care at practices in the middle and highest telemedicine use groups had 1.11 (95% CI, 0.45-1.76) and 1.94 (95% CI, 1.28-2.59) more mental health visits per patient per year (or 7.5% [95% CI, 3.0%-11.9%] and 13.0% [95% CI, 8.6%-17.4%] more mental health visits per year, respectively). Among patients of practices with middle and highest telemedicine use, changes in adherence to antipsychotic and mood-stabilizing medications were -0.4% (95% CI, -1.3% to 0.5%) and -0.1% (95% CI, -1.0% to 0.8%), and hospital and emergency department use for any reason changed by 2.4% (95% CI, -1.5% to 6.2%) and 2.8% (95% CI, -1.2% to 6.8%), respectively. There were no significant differential changes in postdischarge follow-up or mortality rates according to the level of telemedicine use. Conclusions and Relevance: In this cohort study of Medicare beneficiaries with serious mental illness, patients receiving care from practices that had a higher level of telemedicine use during the COVID-19 pandemic had more mental health visits per year compared with prepandemic levels, with no differential changes in other observed quality metrics over the same period.

Racial disparities in utilization of first-generation versus second-generation long-acting injectable antipsychotics in Medicaid beneficiaries with schizophrenia.

BACKGROUND: Multiple studies report racial disparities in antipsychotic prescription patterns. This study assessed demographic and clinical factors associated with the utilization of first-generation (FG) versus second-generation (SG) long-acting injectable (LAI) antipsychotics. METHODS: This retrospective, observational cohort analysis used claims data from the IBM MarketScan® Multi-State Medicaid database. The study included adults with an LAI claim between 01-January-2009 and 31-December-2018, an ICD-9-CM or ICD-10-CM diagnosis of schizophrenia, race recorded as Black or White, and ≥12 months of continuous enrollment before the index LAI. Descriptive analysis detailed the relationship between race and FG or SG LAI initiation. Multivariate logistic regression was used to assess potential associations with FG vs. SG LAI initiation, including clinical and demographic factors, comorbidities, and index year. RESULTS: A total of 10,773 patients were included: 6659 (62 %) Black and 4114 (38 %) White. Black patients had a higher utilization of FG LAIs than White patients (46.8 % vs. 38.9 %) over the 10 years analyzed. Black patients were more likely to utilize FG LAIs than White patients (odds ratio: 1.47; 95 % CI: 1.34, 1.62) after controlling for index year and covariates (race, age, gender, insurance plan type, Quan-Charlson Comorbidity index score, comorbidities, prior medications). Significant predictors of FG LAI utilization were older age, type of baseline oral antipsychotic (FG vs SG), type of coverage (managed care vs fee for service), and greater comorbidity burden. CONCLUSION: The utilization of FG LAIs was greater in Black compared to White Medicaid beneficiaries with schizophrenia over a 10-year period. These findings suggest that racial disparities exist in LAI initiation, with implications for differential quality of schizophrenia treatment.

Comparison of health resource usage and costs associated with first-generation and second-generation long-acting injectable antipsychotics for patients with schizophrenia: A nationwide population-based cohort study.

The aim of this study was to examine psychiatric resource utilization, medical costs and clinical outcomes for patients with schizophrenia who received either first-generation or second-generation long-acting injectable (LAI) antipsychotics. A retrospective cohort study was conducted using data from Taiwan's National Health Insurance Research Database (NHIRD). Patients who began either first-generation or second-generation LAI treatment between 2015 and 2017 were enrolled and followed for three years. The data were evaluated using survival analysis and Cox proportional hazards regression models. Our findings demonstrated that both first- and second-generation LAI therapies led to notable reductions in the frequency of psychiatric hospitalizations and the duration of hospital stays when compared to the initial measurements. Additionally, the second-generation LAI group exhibited significantly lower rates of psychiatric emergencies and hospitalizations, as well as shorter hospital stays, compared to the first-generation LAI group. However, it is worth noting that the second-generation LAI group incurred higher pharmacy fees despite these favorable outcomes. The utilization of both first- and second-generation LAIs can enhance medication adherence and decrease the risk of acute exacerbation in patients with schizophrenia. These findings hold significant implications for schizophrenia management and the efficient allocation of healthcare resources.

Racial and Ethnic Disparities in Long-Acting Injectable Antipsychotic Use in a National Sample of Medicare Beneficiaries With Schizophrenia.

This cross-sectional study assesses the racial and ethnic disparities in long-acting injectable antipsychotic use in a national sample of Medicare beneficiaries with schizophrenia.

The Lifetime Burden of Schizophrenia as Estimated by a Government-Centric Fiscal Analytic Framework.

Objective: To estimate the fiscal consequences of schizophrenia compared to the general US population using a "government perspective" fiscal analytic modeling framework capturing lost tax revenue and broader government costs in 2021.Methods: Schizophrenia was modeled from age 23 using a cohort-based Markov chain with 6-week cycles, simulating the effect of antipsychotic treatment sequences on remission and relapse. Markov states were defined using efficacy and safety outcomes from short- and long-term clinical trials. Mortality was based on US lifetables, schizophrenia-related suicide, and cardiovascular risks. A semi-Markov model with annual cycles simulated the likelihood and costs of incarceration and homelessness in community-based individuals. Lifetime fiscal consequences were estimated conditionally to survival, remission/relapse status, and likelihood of socioeconomic outcomes. Costs and life years were discounted at 3.0% annually. Uncertainty was explored in 1-way and scenario analyses.Results: Unemployment, disability, incarceration, homelessness, health care use, and productivity losses were more common in people living with schizophrenia. Schizophrenia was associated with a $1,540,042 per person lifetime fiscal loss to the government, with $56,707 per life year lived with schizophrenia. Health care costs represented 41.9% of the fiscal losses, 39.4% were due to criminal and homelessness costs, and 17.5% related to foregone tax revenue. Considering a 1.19% prevalence of schizophrenia, the estimated annual fiscal burden in the US was $173.6 billion.Conclusions: The fiscal framework illustrates how schizophrenia influences taxation and government transfer payments over time. These findings can be used to augment cost-effectiveness analyses and inform stakeholders of the fiscal impact of schizophrenia to inform priority interventions.

Construction of a hydrophobic-hydrophilic open-droplet microfluidic chemosensor towards colorimetric/spectrophotometric recognition of quetiapine fumarate: a cost-benefit method for biomedical analysis using a smartphone.

Quetiapine fumarate (QF) is used to treat a number of mental/emotional diseases, including schizophrenia, bipolar disorder, and abrupt bouts of mania or depression linked to bipolar disorder. This antipsychotic medicine can be deadly if an overdose is given to a person. Therefore, the sensitive identification of QF in bodily fluids is very important. In this study, an innovative low-cost colorimetric chemosensor based on silver nanoprism transfiguration in a phosphate-buffered saline (PBS)/Cl- matrix was developed and successfully tested for the recognition of QF in human-exhaled breath condensate. Using this non-invasive colorimetric chemosensor, a broad linearity range of 0.001-1000 µM and a low limit of quantification of 0.001 µM for QF were attained. Notably, the proposed optical chemosensor is capable of detecting QF from a minimum amount of sample [500 µM in PBS and 0.001 µM in exhaled breath condensate] in the first few seconds of reaction by the naked eye. So, a rapid colorimetric assay for the on-site analysis of QF was developed and validated. Moreover, for the first time, a semi-analytical method was introduced that can provide a rough estimation of the QF concentration. This colorimetric system was, for the first time, integrated in an optimized microfluidic paper-based colorimetric device (µPCD), promising the development of an engineered colorimetric opto-sensor toward real-time and therapeutic drug monitoring (TDM) assay of drugs in real-world samples.

Prevalence and impact of antipsychotic discontinuation among commercially-insured patients with bipolar disorder.

BACKGROUND: Antipsychotic discontinuation is common among patients with bipolar disorder, especially when psychotic symptoms are remitted. This analysis describes the prevalence, predictors, and economic impact of antipsychotic discontinuation among patients with bipolar disorder. METHODS: A retrospective, observational study was conducted using administrative claims data in the IBM MarketScan Commercial Database. Patients with ≥1 claim with a diagnosis for bipolar disorder (manic or mixed) and newly-initiating antipsychotic therapy between 1 January 2011 and 30 June 2016 were included. Baseline characteristics were assessed in the 12 months prior to the initiation. Outcomes were assessed during a 24-month follow-up. Discontinuation of antipsychotic therapy was utilized as a predictor of healthcare costs in models adjusted for baseline characteristics. Using limited set of variables in the claims database, predictors of discontinuation were also assessed. RESULTS: A total of 18,259 commercially-insured patients were identified as initiators of antipsychotics. Common comorbidities among the cohorts included major depressive disorder and dyslipidemia. Discontinuation was very common among these patients (85%). Major depressive disorder, drug abuse, and other substance abuse/dependency were predictive of discontinuation. Controlling for differences in baseline characteristics, discontinuation was associated with 33% higher inpatient and emergency visit costs (p <.001) among those using these services, and 24% higher total healthcare costs (p <.001) for the overall cohort. CONCLUSIONS: Most patients with bipolar mania or mixed states discontinue antipsychotic treatment in less than 2 years. Antipsychotic discontinuation contributes to excess healthcare costs. Future research focusing on the reasons for discontinuation and tailoring disease management based on comorbidities may inform adherence improvement initiatives.

Continuity of care among patients newly initiated on second-generation oral or long-acting injectable antipsychotics during a schizophrenia-related inpatient stay.

BACKGROUND: Maintaining continuity of care after schizophrenia-related hospitalization is challenging for patients and healthcare providers and systems. Prior evidence suggests that second-generation long-acting injectable antipsychotics (SGLAIs) may reduce the risk of treatment nonadherence and readmission versus oral atypical antipsychotics (OAAs). Therefore, quality measures were compared between patients initiated on SGLAIs and OAAs in the United States. METHODS: Adults newly initiated on an SGLAI or OAA during a schizophrenia-related inpatient stay were identified in HealthVerity databases (01/2015-12/2020); the index date was the hospital discharge date. Patients had continuous health insurance coverage for pharmacy and medical services for 6 months pre-admission and post-discharge from the inpatient stay and ≥1 pharmacy or medical claim (i.e. treatment as indicated by the observed insurance claims) for an antipsychotic other than the index SGLAI or OAA in the 6 months pre-admission. Antipsychotic use and adherence, and schizophrenia-related readmissions and outpatient visits were compared during the 6-month period post-discharge. Characteristics between cohorts were balanced using inverse probability weights. RESULTS: Post-discharge, only 36.9% and 40.7% of weighted SGLAI (N = 466) and OAA (N = 517) patients had ≥1 pharmacy or medical claim for the antipsychotic initiated during the inpatient stay, among whom SGLAI patients were 4.4 times more likely to be adherent to that antipsychotic compared to OAA patients (p < .001). Additionally, SGLAI patients were 2.3 and 3.0 times more likely to have a pharmacy or medical claim for and be adherent to any antipsychotic relative to OAA patients (including index antipsychotic; all p < .001). Within 7 and 30 days post-discharge, 1.7% and 13.0% of SGLAI patients and 4.1% and 12.6% of OAA patients had a readmission. Further, SGLAI patients were 51% more likely to have an outpatient visit compared to OAA patients (p = .044). CONCLUSIONS: Less than half of patients initiated on antipsychotics during a schizophrenia-related inpatient stay continued the same treatment post-discharge. However, SGLAI patients were more likely to be adherent to the initiated antipsychotic and to have an outpatient visit, which may suggest improved continuity of care post-discharge relative to OAA patients.
