All-cause mortality risk in long-acting injectable versus oral antipsychotics in schizophrenia: a systematic review and meta-analysis. Mol Psychiatry 2024:10.1038/s41380-024-02694-3. [PMID: 39174648 DOI: 10.1038/s41380-024-02694-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 08/01/2024] [Accepted: 08/05/2024] [Indexed: 08/24/2024]
Abstract
Patients with schizophrenia receiving antipsychotic treatment present lower mortality rates than those who do not. However, the non-adherence rate is high, which can be partially addressed using long-acting injectable (LAI) antipsychotics. The impact of LAI treatments on all-cause mortality compared to oral antipsychotics remains unclear. To fill that gap, a random effects meta-analysis was conducted to analyze the odds ratio (OR) of all-cause, suicidal, and non-suicidal mortality among patients taking LAI antipsychotics compared to oral antipsychotics (PROSPERO:CRD42023391352). Individual and pooled LAI antipsychotics were analyzed against pooled oral antipsychotics. Sensitivity analyses were performed for study design, setting, and industry sponsorship. Meta-regressions were conducted for gender, age, antipsychotic dose, and race. Seventeen articles, total sample 12,042 patients (N = 5795 oral, N = 6247 LAI) were included. Lower risk of all-cause mortality for patients receiving LAI antipsychotics vs receiving oral antipsychotics was found (OR = 0.79; 95%CI = 0.66-0.95). Statistical significance was maintained when only studies comparing the same LAI and oral antipsychotic were included (OR = 0.79; 95%CI = 0.66-0.95; p = <0.01), as well as for non-suicidal mortality (OR = 0.77: 95%CI = 0.63-0.94; p = 0.01), but not for suicidal mortality (OR = 0.86; 95%CI = 0.59-1.26; p = 0.44). Mortality reduction was more pronounced for LAI antipsychotics in first-episode psychosis (FEP) (OR = 0.79; 95%CI = 0.66-0.96) compared to chronic psychosis. No individual LAI reported statistically significant differences against all pooled oral antipsychotics. LAI antipsychotics are associated with a lower risk of all-cause and non-suicidal mortality in individuals with schizophrenia compared to oral antipsychotics. Better adherence to the medication and health services may explain this difference. Whenever possible, the use of LAIs should be considered from the FEP.

Abstract
Given the existing uncertainty regarding the effectiveness and safety of switching from low-molecular-weight heparin (LMWH) to direct oral anticoagulants (DOACs) in patients with cancer-associated venous thrombosis (CAT), we conducted a comprehensive population-based cohort study utilizing electronic health database in Hong Kong. A total of 4356 patients with CAT between 2010 and 2022 were included, with 1700 (39.0%) patients switching to DOAC treatment. Compared to continuous LMWH treatment, switching to DOACs was associated with a significantly lower risk of hospitalization due to venous thromboembolism (HR: 0.49 [95% CI = 0.35-0.68]) and all-cause mortality (HR: 0.67 [95% CI = 0.61-0.74]), with no significant difference in major bleeding (HR: 1.04 [95% CI = 0.83-1.31]) within six months. These findings provide reassurance regarding the effectiveness and safety of switching from LMWH to DOACs among patients with CAT, including vulnerable patient groups.

Abstract
OBJECTIVE This study compares demographic, clinical characteristics, and outcomes in older adults on long-acting injectable antipsychotics (LAI-AP) vs. oral antipsychotics (PO-AP). DESIGN This observational study with a retrospective cohort utilized the electronic medical record's search engine to review charts of geriatric patients on LAI-AP for a two-year period. A convenience sample on PO-AP formed the comparison group. LAI-AP patients were subcategorized into discontinuation and continuation groups. SETTING Conducted at an urban, psychiatric outpatient clinic, using charts from October 2020 to 2022. PARTICIPANTS Patients at least 60 years-old with psychotic or mood disorders on antipsychotics for at least 3-months during the study period. MEASUREMENTS Demographic and clinical variables, including diagnosis, medication type, side effects, medical comorbidities, neurocognitive status, and secondary medications, were collected for both PO-AP and LAI-AP groups. Outcome variables included missed appointments, psychiatric and medical hospitalizations, and emergency room visits. Correlates of discontinuation of LAI-AP were also assessed. RESULTS LAI-AP had a higher proportion than PO-AP of primary psychotic disorders (87.8% vs. 64.3%). During the study, PO-AP had higher rates of missed appointments (median 18% vs. 13% for LAI-AP) and psychiatric admissions (mean 0.019/month vs. 0.006/month for LAI-AP;); Female sex was a risk factor for discontinuation of LAI-AP (86.7% of discontinuation group vs. 55.2% of continuation group). CONCLUSIONS The LAI-AP group showed reduced hospitalizations, better treatment engagement, and comparable tolerability to PO-AP. Preliminary data suggests gender may influence LAI-AP discontinuation rates. This study adds to the sparse literature investigating the efficacy and tolerability of LAI-AP in geriatric patients.

Abstract
WHAT IS KNOWN ON THE SUBJECT People living with schizophrenia spectrum disorder (SSD) have a higher death rate which is caused, in part, by poorer adherence to treatment as compared to those with other mental illnesses. Using long-acting injectable antipsychotic (LAI) medications can improve medication adherence and reduce hospitalizations for people living with SSD but are often underutilized. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE As compared to oral antipsychotic medications provided to patients with SSD at discharge from a psychiatric hospitalization, being provided with an LAI antipsychotic medication may reduce subsequent rehospitalization. Specifically, patients discharged on an atypical or second-generation LAI medication are less likely to be readmitted to the hospital when compared to those discharged on a typical first-generation oral medication. WHAT ARE THE IMPLICATIONS FOR PRACTICE Because LAI antipsychotic medications are often underutilized as treatment options, the study findings suggest that this modality may be considered for patients with SSD when being discharged from a psychiatric hospitalization. Ideally, psychiatric-mental health nurses can educate patients about indications, benefits, and risks of using atypical or second-generation LAI antipsychotic medications during hospitalization and at discharge prevent the risk for future rehospitalizations. ABSTRACT INTRODUCTION: People living with schizophrenia spectrum disorder (SSD) have poorer medication adherence compared to those with other mental illnesses. Long-acting injectable antipsychotic (LAI) medication use is associated with greater adherence, reduced re-hospitalizations, and improved recovery outcomes when compared to oral formulations. AIM To compare LAI antipsychotic medication use versus oral formulations on readmission to an inpatient hospital. METHOD Medical records (N = 707) from a state psychiatric hospital in the southern region of the United States were reviewed. Controlling for demographic variables, logistic regression analyses were used to examine LAI compared to oral formulations on readmission. RESULTS Compared to patients discharged with oral antipsychotic medications, those with LAIs had a lower proportion of readmission rates in 6-month and 1-year periods, but not 30-day or 2-year periods. When controlling for demographic variables, those discharged with an atypical LAI had significantly lower odds of being readmitted within the 24-year period compared to those discharged on a typical oral antipsychotic. DISCUSSION Compared to orals, LAIs do not increase and may mitigate readmissions to psychiatric hospitalization. IMPLICATIONS FOR PRACTICE Psychiatric-mental health nurses and other professionals may recommend LAIs when indicated for those with SSD.

Abstract
Background Schizophrenia is most times a chronic and often debilitating illness associated with poor mental health outcomes. Early and effective treatment of schizophrenia in the most appropriate setting can make a significant difference in the long-term recovery. The aim of this narrative review was to provide suggestions and recommendations for effectively managing patients with schizophrenia during acute exacerbations and to enhance awareness and skills related to personalized medicine. Methods A panel of academics and clinicians with experience in the field of psychosis met virtually on July 13th 2023 to narratively review and discuss the research evidence and their clinical experience about the most appropriate acute treatments for patients with schizophrenia. This manuscript represents a synthesis of the panel analysis and discussion. Results First contact is very important for service users, as is finding the most adequate treatment setting. If patients present to the emergency department, which may be a traumatic setting for service users, a dedicated environment with adequate space and specialized mental health support, including personnel trained in de-escalation techniques, is recommended. A well-connected continuum of care is strongly recommended, possibly with seamless links between inpatient units, day hospital services, outpatient facilities and rehabilitation services. Ideally, this should be structured as part of a coordinated step-down service line. Treatment challenges include suboptimal response, side effects, and nonadherence, which is reduced by the use of long-acting injectable antipsychotics. Conclusion Individual circumstances, including age, gender, and presence of hostility/aggression or self-harm, cognitive impairment and negative symptoms, comorbidities (depression, substance use disorders) or associated symptoms (anxiety, insomnia), should be considered when selecting the most appropriate treatment for the acute phase of schizophrenia. Efficacy and feasibility, as well as acceptability and tolerability of treatments, require joint consideration from the early stages of schizophrenia, thereby enhancing the possibility of improved short- and long-term outcomes.

Abstract
BACKGROUND Schizophrenia is one of the leading causes of disability. Paliperidone palmitate once-monthly injection (PP1M) was developed to provide consistent drug delivery and improve medication adherence for maintenance treatment. It is well known that patients with schizophrenia have higher cardiovascular risks, however little is known about the cardiovascular risks of patients with schizophrenia treated with PP1M in Asia. OBJECTIVE This study aimed to estimate the incidence of cardiovascular events after initiating PP1M treatment and evaluate the cardiovascular risk associations compared with oral second-generation antipsychotics (SGAs). METHODS Data from Taiwan's National Health Insurance Research Database were used to identify a cohort of adult patients with schizophrenia who received any SGAs from 1 March 2012 to 31 December 2018. Patients who initiated PP1M treatment were enrolled for descriptive analysis of incidence rates. PP1M patients were propensity matched 1:1 to patients initiating a new oral SGA, for comparative analysis based on demographics, clinical characteristics and treatment history at baseline, in three-step matching procedures, following the prevalent new-user design to enhance comparability. Follow-up ended at the end of the treatment episode of index drug, death, last record available, or end of the study (31 December 2019). Study endpoints included serious cardiovascular events (including severe ventricular arrhythmia and sudden death), expanded serious cardiovascular events (which further included acute myocardial infarction and ischemic stroke), and cardiovascular hospitalizations. Risks of study endpoints between matched cohorts were compared using Cox regression. RESULTS Overall, 11,023 patients initiating PP1M treatment were identified (49.5% were females; mean age of 43.2 [12.2] years). Overall incidences for serious cardiovascular events, expanded serious cardiovascular events, and cardiovascular hospitalizations were 3.92, 7.88 and 51.96 per 1000 person-years, respectively. In matched cohort analysis (N = 10,115), the hazard ratios (HRs) between initiating PP1M and a new oral SGA for serious cardiovascular events, expanded serious cardiovascular events, and cardiovascular hospitalizations were 0.86 (95% confidence interval [CI] 0.55-1.36), 0.88 (95% CI 0.63-1.21), and 0.78 (95% CI 0.69-0.89), respectively. CONCLUSION This study reported the population-based incidence of cardiovascular events in schizophrenic patients initiating PP1M treatment. PP1M was not associated with increased risks of serious cardiovascular events but was potentially associated with lower risks of cardiovascular hospitalizations compared with oral SGAs.

Abstract
Introduction Studies indicate that long-acting injectable antipsychotics (LAIAs) reduce the risk of relapse and hospitalization compared with oral antipsychotics (APs) in adults. Oral formulations of APs are well-studied in the pediatric population, but little is known regarding the off-label use of LAIAs in this population. Methods This retrospective chart review evaluated readmission rates for pediatric patients admitted to a psychiatric ward in a large academic hospital between January 1, 2015, and December 1, 2022, requiring AP therapy. The experimental group included patients initiated on LAIA therapy, and the control group included patients initiated on a new oral AP. Patients were matched by several clinical factors. Results Each group consisted of 38 patients. For the primary outcome, hospital readmission rates at 3 months, the LAIA group had a 13.2% readmission rate compared with 26.3% in the comparator group (p = .153). In months 4 through 6, there was a 5.3% versus 15.8% readmission rate, respectively (p = .139). In months 7 through 12, it was 7.9% versus 18.4% (p = .179). There were significantly fewer cumulative readmissions at the 1-year mark in the LAIA group (N = 9, 23.7%) compared with the oral AP group (N = 18, 47.4%) (p = .031). No statistically significant differences were seen in hospital length of stay although results numerically favored LAIA. Discussion In a pediatric population, the administration of an LAIA when compared with the oral equivalent resulted in numerically fewer hospital readmissions, decreased length of stay, and fewer adverse effects, but these effects were not statistically significant except for cumulative readmissions at 1 year.

Abstract
BACKGROUND AND HYPOTHESIS Long-acting injectable antipsychotic drugs (LAIs) are mainly used for relapse prevention but could also be advantageous for acutely ill patients with schizophrenia. STUDY DESIGN We conducted a systematic review and meta-analysis of randomized-controlled-trials (RCTs) comparing the second-generation long-acting injectable antipsychotics (SGA-LAIs) olanzapine, risperidone, paliperidone, and aripiprazole with placebo or their oral counterparts in acutely ill patients with schizophrenia. We analyzed 23 efficacy and tolerability outcomes, with the primary outcome being overall symptoms of schizophrenia. The results were obtained through random effects, pairwise meta-analyses, and subgroup tests. The study quality was assessed using the Cochrane-Risk-of-Bias-Tool version-1. STUDY RESULTS Sixty-six studies with 16 457 participants were included in the analysis. Eleven studies compared second-generation long-acting injectable antipsychotics (SGA-LAIs) with a placebo, 54 compared second-generation oral antipsychotics (SGA-orals) with a placebo, and one compared an SGA-LAI (aripiprazole) with its oral formulation. All 4 SGA-LAIs reduced overall symptoms more than placebo, with mean standardized differences of -0.66 (95% CI: -0.90; -0.43) for olanzapine, -0.64 (-0.80; -0.48) for aripiprazole, -0.62 (-0.76; -0.48) for risperidone and -0.42 (-0.53; -0.31) for paliperidone. The side-effect profiles of the LAIs corresponded to the patterns known from the oral formulations. In subgroup tests compared to placebo, some side effects were less pronounced under LAIs than under their oral formulations. CONCLUSIONS SGA-LAIs effectively treat acute schizophrenia. Some side effects may be less frequent than under oral drugs, but due to the indirect nature of the comparisons, this finding must be confirmed by RCTs comparing LAIs and orals head-to-head.

Asian J Psychiatr 2024; 91:103857. [PMID: 38128353 DOI: 10.1016/j.ajp.2023.103857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/27/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023]
Abstract
INTRODUCTION Given the similar efficacies across antipsychotic medications for schizophrenia, understanding their safety profiles, particularly concerning receptor-binding differences, is crucial for optimal drug selection, especially for patients with first episode schizophrenia. We aimed to compare the safety outcomes of second-generation antipsychotics. METHODS We conducted a retrospective cohort study with new user active comparator design using a nationwide claims database in South Korea. Participants were drug-naïve adult patients with first-episode schizophrenia. Three representative drugs with different pharmacologic profiles were compared: risperidone, olanzapine, and aripiprazole. Propensity scores were used to match the study groups, and the Cox proportional hazard model was used to calculate hazard ratios. Sensitivity analyses were performed in various epidemiological settings. Seventeen safety outcomes, including neuropsychiatric, cardiometabolic and gastrointestinal events, were assessed, with upper-respiratory-tract infection as a negative control outcome. RESULTS A total of 1044, 2078, and 3634 participants were matched for olanzapine vs. risperidone, olanzapine vs. aripiprazole, and risperidone vs. aripiprazole comparisons, respectively. For parkinsonism, there was a significant difference in outcomes between the risperidone and aripiprazole groups (HR 1.80 [95% CI 1.13-2.91]), with consistent sensitivity analysis results. There were no significant differences in other neuropsychiatry outcomes or in the risk of cardiometabolic and gastrointestinal outcomes between any of the comparative group pairs. CONCLUSIONS The risk of drug-induced parkinsonism was significantly higher with risperidone than with aripiprazole. Although olanzapine is known for its metabolic risk, there were no significant differences in risk between the other pairs.

Association between cumulative exposure periods of flupentixol or any antipsychotics and risk of lung cancer. COMMUNICATIONS MEDICINE 2023; 3:126. [PMID: 37752185 PMCID: PMC10522572 DOI: 10.1038/s43856-023-00364-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 09/18/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Preclinical evidence suggests that certain antipsychotic medications may inhibit the development of lung cancer. This study aims to investigate the association between incident lung cancer and different cumulative exposure periods of flupentixol or any antipsychotics. METHODS Using electronic health records from the Hospital Authority in Hong Kong, this nested case-control study included case participants aged 18 years or older with newly diagnosed lung cancer after initiating antipsychotics between January 1, 2003, and August 31, 2022. Each case was matched to up to ten controls of the same sex and age, who were also antipsychotic users. Multivariable conditional logistic regression models were conducted to quantify the association between lung cancer and different cumulative exposure times of flupentixol (0-365 days [ref]; 366-1825 days; 1826+ days) and any antipsychotics (1-365 days [ref]; 366-1825 days; 1826+ days), separately. RESULTS Here we show that among 6435 cases and 64,348 matched controls, 64.06% are males, and 52.98% are aged 65-84 years. Compared to patients with less than 365 days of exposure, those with 366-1825 days of exposure to flupentixol (OR = 0.65 [95% CI, 0.47-0.91]) and any antipsychotics (0.42 [0.38-0.45]) have a lower risk of lung cancer. A decreased risk is observed in patients who have 1826+ days of cumulative use of any antipsychotics (0.54 [0.47-0.60]). CONCLUSIONS A reduced risk of lung cancer is observed in patients with more than one year of exposure to flupentixol or any antipsychotics. Further research on the association between lung cancer and other antipsychotic agents is warranted.

Abstract
Evidence of comparative benefits of long-acting injectable (LAI) antipsychotics in Asian patients with schizophrenia has been inconsistent. This scoping review aimed to synthesize the current evidence in the past ten years and provide an overview of efficacy, safety, treatment adherence, patient attitudes, and healthcare resource utilization of LAI in this population. A systematic search was conducted with a pre-defined search strategy in six electronic databases including Chinese National Knowledge Infrastructure (CNKI), Wanfang, PubMed, Embase, CINAHL, and PsycArticles. A total of 46 studies were included, including 15 cohort studies, 13 single-arm trials, 10 randomized controlled trials, four mirror-image studies, three cross-sectional studies, and one controlled clinical trial. Paliperidone palmitate once-monthly injection (27/46) and risperidone LAI (14/46) were the most frequently investigated LAIs. Compared with oral antipsychotic medications (OAMs), LAIs demonstrated a lower rate of relapse/hospitalization and comparable improvement in efficacy. Adverse events (AEs) were similar between LAIs and OAMs, although types and incidence varied. Significant reduction in the length of hospitalization and number of outpatient visits/inpatient admission was observed after initiation of LAIs. These findings suggest that LAI demonstrated comparable efficacy and safety among Asian populations with schizophrenia in comparison to OAMs. Better adherence and lower relapse were observed in patients receiving LAIs from published evidence. Future research is warranted to better understand the comprehensive performance of LAI in specific population or context.

Time-to-therapy discontinuation in patients newly diagnosed with schizophrenia initiated on long-acting injectable versus oral dopamine receptor blocking agents. Early Interv Psychiatry 2023; 17:921-928. [PMID: 36639353 DOI: 10.1111/eip.13384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 12/06/2022] [Accepted: 01/01/2023] [Indexed: 01/15/2023]
Abstract
AIM The purpose of this project is to assess the time-to-therapy discontinuation and hospital readmission rate among patients newly diagnosed with schizophrenia who are prescribed long-acting injectable versus oral dopamine receptor blocking agents. METHODS A retrospective review of medical records was performed for adult patients admitted to an 80-bed inpatient behavioural health facility with a new diagnosis of schizophrenia. The primary outcome studied was time to therapy discontinuation within 1 year of discharge, while secondary outcomes assessed were time-to-therapy discontinuation within 90 days and readmission rate at 30-days, 6 months, and 1 year. Multivariate Cox proportional hazard and linear regression modelling were used for statistical analysis. RESULTS A total of 425 patients were included in the analysis, with 66.4% (n = 282) discharged on oral and 33.6% (n = 143) on long-acting injectable dopamine receptor blocking agents. At 1 year post-discharge, the rates of discontinuation were 49.7% for those prescribed long-acting injectable and 55.7% for those prescribed oral formulations (adjusted hazard ratio = 0.54, p = .012). There was no statistically significant difference in readmission rate between the patients prescribed long-acting injectable and oral dopamine receptor blocking agents at any timepoint tested. CONCLUSIONS The use of long-acting injectable dopamine receptor blocking agents was associated with longer time-to-discontinuation compared to oral agents when prescribed to patients newly diagnosed with schizophrenia in the inpatient setting. However, this was not associated with significant reductions in rehospitalization, calling into question the clinical impact. Future studies will seek to confirm these findings using a prospective study design.

Medicine (Baltimore) 2023; 102:e34623. [PMID: 37653768 PMCID: PMC10470698 DOI: 10.1097/md.0000000000034623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 07/07/2023] [Accepted: 07/14/2023] [Indexed: 09/02/2023] Open
Abstract
BACKGROUND Evaluate efficacy and safety of paliperidone palmitate 6-monthly (PP6M) for patients with schizophrenia in the Asian subgroup of a global, multicenter, noninferiority phase-3 study (NCT03345342). METHODS Patients received paliperidone palmitate 1-monthly (PP1M, 100/150 mg eq.) or paliperidone palmitate 3-monthly (PP3M, 350/525 mg eq.) during the maintenance phase and entered a 12-month double-blind (DB) phase, wherein they were randomized (2:1) to PP6M (700/1000 mg. eq.) or PP3M (350/525 mg eq.). Subgroup analysis was performed for 90 (12.7%) patients from Asia region (India, Taiwan, Malaysia, Hong Kong, and Korea). Primary endpoint was time-to-relapse during DB phase (Kaplan-Meier estimates). Secondary endpoints were changes from baseline in Positive and Negative Syndrome Scale, Clinical Global Impression-Severity scale, Personal and Social Performance (PSP) scale score. RESULTS In Asian subgroup, 91.9% (82/90) of patients completed DB phase (PP6M: 54/62 [87%]; PP3M: 28/28 [100%]). Median time-to-relapse was "not-estimable" due to low relapse rates in both groups. Estimated difference (95% confidence interval [CI]) between relapse-free patients in PP6M and PP3M groups of Asian subgroup was -0.1% [-8.5%, 8.4%] (global study population: -2.9% [-6.8%, 1.1%]). Mean change from baseline in secondary efficacy parameters was comparable between both groups, similar to the global study population. The incidence of extrapyramidal symptoms was higher in the Asian subgroup than in the global study population. CONCLUSION Consistent with the global study population, PP6M was noninferior to PP3M in preventing relapse in patients with schizophrenia from the Asia region. Findings suggest the possibility of switching from PP1M/PP3M to twice-yearly PP6M without loss of efficacy and with no unexpected safety concerns.
