Experiences managing behavioral symptoms among Latino caregivers of Latino older adults with dementia and memory problems: a qualitative study.

BACKGROUND: Latinos are more likely than non-Latino Whites to develop dementia and be prescribed antipsychotics for dementia-related behavioral symptoms. Antipsychotics have significant risks yet are often overprescribed. Our understanding of how Latino caregivers of Latino older adults living with dementia perceive and address behavioral issues is limited, impeding our ability to address the root causes of antipsychotic overprescribing. METHODS: We interviewed Latino older adults' caregivers and community-based organization workers serving older adults with cognitive impairment (key informants), focusing on the management of behavioral symptoms and experiences with health services. RESULTS: We interviewed 8 caregivers and 2 key informants. Caregivers were the spouses, children, or grandchildren of the older adult living with cognitive impairment; their ages ranged from 30 to 95. We identified three categories of how caregivers learned about, managed, and coped with behavioral symptoms: caregivers often faced shortcomings with dementia care in the medical system, receiving limited guidance and support; caregivers found community organizations and senior day centers to be lifelines, as they received relevant, timely advice and support, caregivers often devised their own creative strategies to manage behavioral symptoms. CONCLUSION: In-depth interviews suggest that the healthcare system is failing to provide support for behavioral symptoms from dementia; caregivers of Latino older adults rely on community organizations instead.

Exploring the Relationships Between Antipsychotic Dosage and Voice Characteristics in Relation to Extrapyramidal Symptoms.

OBJECTIVE: Extrapyramidal symptoms (EPS) are common side effects of antipsychotic drugs. Despite the growing interest in exploring objective biomarkers for EPS prevention and the potential use of voice in detecting clinical disorders, no studies have demonstrated the relationships between vocal changes and EPS. Therefore, we aimed to determine the associations between voice changes and antipsychotic dosage, and further investigated whether speech characteristics could be used as predictors of EPS. METHODS: Forty-two patients receiving or expected to receive antipsychotic drugs were recruited. Drug-induced parkinsonism of EPS was evaluated using the Simpson-Angus Scale (SAS). Participants' voice data consisted of 16 neutral sentences and 2 second-long /Ah/utterances. Thirteen voice features were extracted from the obtained voice data. Each voice feature was compared between groups categorized based on SAS total score of below and above "0.6." The associations between antipsychotic dosage and voice characteristics were examined, and vocal trait variations according to the presence of EPS were explored. RESULTS: Significant associations were observed between specific vocal characteristics and antipsychotic dosage across both datasets of 1-16 sentences and /Ah/utterances. Notably, Mel-Frequency Cepstral Coefficients (MFCC) exhibited noteworthy variations in response to the presence of EPS. Specifically, among the 13 MFCC coefficients, MFCC1 (t=-4.47, p<0.001), MFCC8 (t=-4.49, p<0.001), and MFCC12 (t=-2.21, p=0.029) showed significant group differences in the overall statistical values. CONCLUSION: Our results suggest that MFCC may serve as a predictor of detecting drug-induced parkinsonism of EPS. Further research should address potential confounding factors impacting the relationship between MFCC and antipsychotic dosage, possibly improving EPS detection and reducing antipsychotic medication side effects.

Medication burden reduction and early clinical benefit through aripiprazole once monthly in schizophrenia patients with polypharmacy.

Antipsychotic polypharmacy is commonly used in clinical settings, with a growing trend in using long-acting injections to mitigate many side effects of polypharmacy. A previous study demonstrated that long-acting aripiprazole once-monthly (AOM) injection increased treatment adherence, restored functionality, and improved symptoms. However, there is insufficient evidence to demonstrate the therapeutic effects of AOM in polypharmacy practice. This observational study aimed to investigate the real-world clinical benefits and effectiveness of AOM by assessing changes in drug dosage, the number of drugs, clinical functioning, psychotic symptoms, and the duration of drug efficacy. Study participants were recruited from eight study sites, with the baseline visit marking the initiation of drug treatment. Clinical and demographic data were collected from medical records at screening, baseline, and months 1, 3, 6, 9, and 12. Over 12 months, we analyzed changes in drug dosage, the number of drugs, and scores of the Positive and Negative Syndrome Scale-6 (PANSS-6), Global Assessment of Functioning (GAF), and Clinical Global Impression-Severity (CGIS). Data from 139 participants were analyzed. Total 12-month antipsychotic doses calculated in chlorpromazine equivalents (CPE) were reduced by 32.6%. A comparison of total monthly antipsychotic doses in CPE between the first and last months showed a 24.6% reduction in the dose. Additionally, the quantity of benzodiazepine tablets/capsules, total benzodiazepine doses calculated in lorazepam equivalents, and quantity of tablets/capsules of mood stabilizers, anticholinergics, and beta blockers were significantly reduced. GAF scores increased by 14.1% over 12 months, and PANSS-6 total scores reduced by 17.3% over 12 months, with significant differences observed from month 1 and baseline, respectively. The scores steadily improved until month 9 compared to those of the previous months, continuing to improve through month 12. The CGI-S score reduced by 14.3% over 12 months, showing a significant decrease from month 1 and a steady improvement until month 6, maintaining this improvement until month 12. In conclusion, this study demonstrated the early effectiveness of AOM in treating Korean patients with schizophrenia on polypharmacy. AOM improved function and clinical symptoms in patients with schizophrenia from treatment onset and caused a decrease in the quantity and dosage of drugs taken by the patients.

An Updated Safety Review of the Relationship Between Atypical Antipsychotic Drugs, the QTc Interval and Torsades de Pointe As: Implications for Clinical Use.

INTRODUCTION: The rising prevalence of psychiatric disorders has resulted in a significant increase in the use of antipsychotic medications. These agents may prolong the corrected QT interval (QTc), running the risk of precipitating ventricular arrhythmias, notably Torsades de Pointes (TdP). Current recommendations vary regarding the optimal approach to safe prescribing practices and QTc surveillance for antipsychotics. This review summarizes the current literature addressing these clinical concerns. AREAS COVERED: The physiologic basis of the QTc interval, mechanisms underlying its susceptibility to pharmacological influence, specific risks associated with atypical antipsychotic agents, and recommendations for safe prescription practices. We performed a literature review using Pubmed and Embase databases, searching for 'antipsychotics' and 'torsades de pointes.' EXPERT OPINION: Finding a safe and universally accepted protocol for prescribing antipsychotics remains a persistent challenge in medicine. Predictive models that integrate clinical history with demographic and ECG characteristics can help estimate an individual's susceptibility to therapy-associated risks, including QTc prolongation. Agents such as ziprasidone and iloperidone are significantly more likely to prolong the QTc interval compared to others such as brexpiprazole, cariprazine, olanzapine, and clozapine. A personalized approach using low-risk medications when clinically feasible, and at the lowest efficacious dose, offers a promising path toward safer antipsychotic prescribing.

Antipsychotic medications are used to treat conditions such as schizophrenia and bipolar disorder; however, they can also affect cardiac electrical conduction. This effect on cardiac function increases the risk of a dangerous heart rhythm, which can potentially be fatal. Patients and doctors need to be aware of and monitor for these potential heart-related side effects, although antipsychotics can be very helpful for mental health conditions.

Long-term metabolic side effects of second-generation antipsychotics in Chinese patients with schizophrenia: A within-subject approach with modelling of dosage effects.

BACKGROUND: Second-generation antipsychotics (SGAs) are commonly used to treat schizophrenia (SCZ), but SGAs may differ in the severity of side effects. Long-term studies are lacking, and previous observational studies have limitations, such as failure to account for confounding factors and short follow-up durations. AIMS: To compare the long-term anthropometric and metabolic side effects of seven SGAs in a Chinese population, using a within-subject approach to reduce the risk of confounding. METHOD: We collected longitudinal data of SGA prescriptions, concomitant medications, fasting blood glucose (BG), lipid profiles, and BMI in a cohort of 767 patients with SCZ, with follow-up lasting up to 18.7 years (median ∼6.2 years). A total of 192,152 prescription records were retrieved, with 27,723 metabolic measures analysed. Linear mixed models were used to estimate the effects of SGA on BG, lipid profiles and BMI. Besides studying the effects of SGA medications (as binary predictors), we also investigated the effects of SGA dosage on metabolic profiles. RESULTS: Considering SGA medications as binary predictors, clozapine and olanzapine were associated with the most substantial worsening of lipid profiles and BMI. A significant increase in BG was observed with clozapine only. Amisulpride, paliperidone and quetiapine were associated with worsened lipid profiles and increased BMI. Conversely, aripiprazole was associated with significant improvement in lipid profiles but a small increase in BMI. When SGA dosage was considered, the model showed consistent results overall. At the minimum effective dose, clozapine was associated with the most severe metabolic side effects, followed by olanzapine. Risperidone and aripiprazole showed the least metabolic side effects, with aripiprazole being significantly associated with lower lipids. CONCLUSIONS: This study clarified the long-term and dose-dependent effects of different SGAs on anthropometric and metabolic parameters in Chinese SCZ patients. Our findings may inform clinicians and SCZ patients of SGA choices.

Multiple Adverse Reactions Associated With the Use of Second-Generation Antipsychotics in People With Alzheimer's Disease: A Pharmacovigilance Analysis Based on the FDA Adverse Event Reporting System.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative condition leading to memory loss, cognitive impairment, and neuropsychiatric symptoms. Second-generation antipsychotics (SGAs) are commonly used to manage these neuropsychiatric symptoms, but their safety profile in patients with AD requires further investigation. OBJECTIVE: The objective was to evaluate the safety of SGAs in patients with AD by analyzing adverse drug reactions (ADRs) using the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. METHODS: This study conducted a comprehensive analysis of FAERS data from 2014 to 2023, focusing on ADRs in patients with AD treated with SGAs such as risperidone, quetiapine, olanzapine, clozapine, and aripiprazole. Descriptive, disproportionality, time, and dose analysis were performed using the Bayesian confidence propagation neural network, Weibull, and physiologically based pharmacokinetic model. RESULTS: Out of 1289 patients with AD treated with SGAs, the most common ADRs involved the nervous system, gastrointestinal system, and cardiac disorders. Disproportionality analysis identified significant positive signals in cardiac, renal, and vascular systems. Quetiapine, risperidone, and olanzapine showed more positive signals compared with clozapine and aripiprazole. Time analysis indicated that cardiovascular ADRs occurred randomly, whereas renal ADRs increased with prolonged use. Dose analysis suggested that small doses of SGAs did not elevate the risk of multiple cardiac, renal, or vascular ADRs. CONCLUSION AND RELEVANCE: The study underscores the importance of monitoring for ADRs, particularly in the cardiac and renal systems, when using SGAs in patients with AD. Future research incorporating more comprehensive clinical data is warranted to support safe and rational drug utilization.

Prevalence of polypharmacy and factors impacting psychotropic prescribing patterns in women of childbearing potential at inpatient mental health services in Qatar.

AIMS: Women may experience unique mental disorders due to hormone shifts. Rates of schizophrenia and bipolar disorder are similar between genders, but onset and symptoms may differ. Women tend to use more psychotropic drugs due to limited therapeutic options. This study was aimed to estimate the prevalence of psychotropic polypharmacy among females of childbearing potential and factors impacting prescribing patterns. METHODS: This was a quantitative retrospective chart review for patients admitted to inpatient units at the Mental Health Hospital in Qatar. SPSS® Statistics was used for data analysis. In addition to descriptive statistics applied, linear regression and binary logistic regression models were used to examine the clinical and sociodemographic factors associated with polypharmacy and full therapeutic response upon discharge, respectively. An alpha value of 0.05 was used. RESULTS: Of the 347 patients, 52.7% of the patients received a prescription of at least two psychotropic drugs upon discharge. Around two-thirds (63.1%) were prescribed at least one antipsychotic. Potential predictors of polypharmacy were age (p = 0.027), longer hospital stay (p = 0.003), family history (p < 0.001), absence of suicidal history (p = 0.005), and a diagnosis of a mood disorder (p = 0.009), or a diagnosis of a psychotic disorder (p = 0.015). A full response upon discharge was less likely to occur in patients with a longer stay (OR = 0.940; p = 0.029) and in those with a substance use disorder (OR = 0.166; p = 0.035). CONCLUSION: There is a notably high prevalence of total polypharmacy upon discharge. Some identified factors are modifiable. Evidence-based prescription practices through hospital guidelines and education should be emphasized to avoid unreasonable polypharmacy.

Characteristics of eye disorders induced by atypical antipsychotics: a real-world study from 2016 to 2022 based on Food and Drug Administration Adverse Event Reporting System.

Background: Common atypical antipsychotics include risperidone, paliperidone, olanzapine, lurasidone, quetiapine, clozapine, aripiprazole, ziprasidone, asenapine, brexpiprazole, and cariprazine. Previous studies on ocular adverse reactions of antipsychotics were mainly focused on typical antipsychotics. Systematic research on atypical antipsychotics remains limited. Objective: This study aimed to evaluate the potential risks of different atypical antipsychotics causing ocular side effects by mining the Food and Drug Administration Adverse Event Reporting System (FAERS) database. Methods: Extract reports from the FAERS from the first quarter of 2016 to the fourth quarter of 2022 were obtained. Data mining of eye disorders associated with atypical antipsychotics was carried out using The Reporting Odds Ratio (ROR) method and The Medicines and Healthcare Products Regulatory Agency (MHRA) method to determine positive signals. Results: FAERS reports for 9913783 cases were included in these 28 quarters. 64 defined ocular adverse events were classified into 10 categories according to High-Level Group Terms (HLGT). Conclusions: There were differences in the types and severity of ocular-related adverse events associated with atypical antipsychotics. Ocular neuromuscular-related adverse events were found among all 11 atypical antipsychotics. Olanzapine had the highest signal intensity in oculogyric crisis. Aripiprazole had the highest signal strength in blepharospasm. Cariprazine was associated with cataract-related ocular adverse reactions. In terms of the types of adverse events, our study found that aripiprazole was associated with 28 types of ocular adverse events, followed by quetiapine. Clozapine was only associated with two types of ocular adverse events.

Self-prescription with psychotropic medications by healthcare professionals working at mental health institutions in Saudi Arabia.

BACKGROUND: Healthcare professionals who work in mental health institutions are more exposed to psychotropic medications than those in other healthcare institutions and are, therefore, more likely to self-prescribe. Self-prescription is a concerning phenomenon because of the potential for medication misuse, drug interaction, addiction, and other social, physical, and psychological consequences. This study investigated the prevalence of self-prescription of psychotropic medications and the most common self-prescribed psychotropic medications by healthcare professionals in mental health institutions in Saudi Arabia. It also aimed to determine the possible side effects and factors associated with self-prescription of psychotropic medications. MATERIALS AND METHODS: This was a cross-sectional study using an electronic survey consisting of a researcher-designed checklist, targeting healthcare professionals in mental health institutions in Saudi Arabia. The independent variables were sex, nationality, occupation, place of residence, place of work, previous diagnosis of mental illness, marital, and living status. Data were analyzed, using SPSS, and frequency distribution and percentages were calculated. Chi-square test was employed to determine association between self-prescription and various independent variables. RESULTS: The final sample size was 588; 9.5% healthcare professionals working at mental health institutions in Saudi Arabia admitted to self-prescription with psychotropic medications. Almost half of those who admitted to self-prescription (48.2%) and about 1/4 (23.2%) self-prescribed selective serotonin reuptake inhibitors and benzodiazepines, respectively. The most commonly reported side effects of self-prescription were gastrointestinal symptoms and drowsiness. The study also suggested that males were significantly more prone to self-prescribing than females (P < 0.001). CONCLUSION: To our knowledge, this is the first study in Saudi Arabia to assess the self-prescription of psychotropic medications by healthcare professionals at mental health institutions. This study is important for decision-makers in their planning and updating of prescription policies. It is also equally important to spread awareness among healthcare professionals about the consequences of self-prescription.

Pharmacological Treatment of Cognitive Impairment Associated With Schizophrenia: State of the Art and Future Perspectives.

Cognitive Impairment Associated with Schizophrenia (CIAS) represents one of the core dimensions of Schizophrenia Spectrum Disorders (SSD), with an important negative impact on real-world functional outcomes of people living with SSD. Treatment of CIAS represents a therapeutic goal of considerable importance, and while cognition-oriented evidence-based psychosocial interventions are available, effective pharmacological treatment could represent a game-changer in the lives of people with SSD. The present critical review reports and discusses the evidence regarding the effects of several pharmacological agents that are available in clinical practice or are under study, commenting on both current and future perspectives of CIAS treatment. In particular, the effects on CIAS of antipsychotic medications, anticholinergic medications, benzodiazepines, which are currently commonly used in the treatment of SSD, and of iclepertin, d-serine, luvadaxistat, xanomeline-trospium, ulotaront, anti-inflammatory molecules, and oxytocin, which are undergoing regulatory trials or can be considered as experimental agents, will be reported and discussed. Currently, available pharmacological agents do not appear to provide substantial benefits on CIAS, but accurate management of antipsychotic medications and avoiding treatments that can further exacerbate CIAS represent important strategies. Some molecules that are currently being investigated in Phase 2 and Phase 3 trials have provided very promising preliminary results, but more information is currently required to assess their effectiveness in real-world contexts and to provide clear recommendations regarding their use in clinical practice. The results of ongoing and future studies will reveal whether any of these molecules represents the awaited pharmacological game-changer in the treatment of CIAS.

Identifying clinically relevant agranulocytosis in people registered on the UK clozapine Central Non-Rechallenge Database: retrospective cohort study.

BACKGROUND: Clozapine is the most effective antipsychotic for treatment-resistant psychosis. However, clozapine is underutilised in part because of potential agranulocytosis. Accumulating evidence indicates that below-threshold haematological readings in isolation are not diagnostic of life-threatening clozapine-induced agranulocytosis (CIA). AIMS: To examine the prevalence and timing of CIA using different diagnostic criteria and to explore demographic differences of CIA in patients registered on the UK Central Non-Rechallenge Database (CNRD). METHOD: We analysed data of all patients registered on the UK Clozaril® Patient Monitoring Service Central Non-Rechallenge Database (at least one absolute neutrophil count (ANC) < 1.5 × 109/L and/or white blood cell count < 3.0 × 109/L) between May 2000 and February 2021. We calculated prevalence rates of agranulocytosis using threshold-based and pattern-based criteria, stratified by demographic factors (gender, age and ethnicity). Differences in epidemiology based on rechallenge status and clozapine indication were explored. The proportion of patients who recorded agranulocytosis from a normal ANC was explored. RESULTS: Of the 3029 patients registered on the CNRD with 283 726 blood measurements, 593 (19.6%) were determined to have threshold-based agranulocytosis and 348 (11.4%) pattern-based agranulocytosis. In the total sample (75 533), the prevalence of threshold-based agranulocytosis and pattern-based agranulocytosis was 0.8% and 0.5%, respectively. The median time to threshold-based agranulocytosis was 32 weeks (IQR 184) and 15 (IQR 170) weeks for pattern-based agranulocytosis. Among age groups, the prevalence of pattern-based agranulocytosis and threshold-based agranulocytosis was highest in the >48 age group. Prevalence rates were greatest for White (18%) and male individuals (13%), and lowest for Black individuals (0.1%). The proportion of people who were determined to have pattern-based agranulocytosis without passing through neutropenia was 70%. CONCLUSIONS: Threshold-based definition of agranulocytosis may over-diagnose CIA. Monitoring schemes should take into consideration neutrophil patterns to correctly identify clinically relevant CIA. In marked contrast to previous studies, CIA occurred least in Black individuals and most in White individuals.

Schizophrenia and Heart Health: Are Antipsychotics a Friend or Foe?

Schizophrenia is one of the most disabling of the psychiatric diseases. The Brief Psychiatric Rating Scale Extended (BRSE) is used to evaluate the severity of psychiatric symptoms. Long-acting injectable (LAI) antipsychotics are commonly used and are preferred over oral antipsychotic medications. A two-center-based cross-sectional study was performed on 130 patients diagnosed with schizophrenia or schizoaffective disorder based on the International Classification of Diseases 10 criteria. We studied the relation between the development of cardiovascular risk factors and the antipsychotic medication that was administered in these patients. Our study demonstrates strong links between several cardiovascular risk factors and the duration of psychosis; the duration of the LAI antipsychotic treatment; the duration between the onset of the disease and the start of LAI antipsychotic treatment; and the use of specific LAI antipsychotic medications.

Long-Acting Injectable Antipsychotic Initiation in Child and Adolescent Patients with Psychiatric Disorders.

Objectives: There are currently no long-acting injectable antipsychotics (LAIAs) that are approved by the Food and Drug Administration for use in child and adolescent patients, however these agents are used off-label for the treatment of various psychiatric disorders. This study aims to describe the initiation and maintenance dosing strategies of LAIAs in child and adolescent psychiatry inpatients. Methods: This was a single-site retrospective chart review of patients less than 18 years of age initiated on an LAIA during an acute psychiatric hospitalization between October 1, 2015, and October 31, 2022. Patient demographics and hospital encounter information were collected and analyzed using descriptive statistics. Results: Of the 6402 unique pediatric patients discharged from the acute psychiatric hospital within the specified timeframe, 45 (0.7%) were newly initiated on an LAIA. The average age was 15.6 years (range 10-17), with a greater proportion of male (n = 26, 57.8%) and Black or African American (n = 27, 60%) patients. The LAIA agents prescribed included paliperidone palmitate (n = 21, 46.7%), aripiprazole monohydrate (n = 15, 33.3%), aripiprazole lauroxil (n = 7, 15.6%), haloperidol decanoate (n = 1, 2.2%), and risperidone microspheres (n = 1, 2.2%). Primary diagnosis via International Classification of Diseases-10 code at discharge included schizophrenia spectrum and other psychotic disorders (n = 19, 42.2%); bipolar disorder (n = 14, 31.1%); disruptive, impulse control, and conduct disorders (n = 6, 13.3%); autistic disorder (n = 5, 11.1%); and attention-deficit/hyperactivity disorder (n = 1, 2.2%). Seventeen patients (37.8%) received a loading dose regimen and/or a maintenance dose regimen that differed from adult package-insert dosing. The mean length of stay was 23.7 days, and 14 patients (31.1%) were readmitted to the psychiatric hospital within 6 months of discharge. The mean number of days to readmission was 71.9 days. Conclusions: This retrospective study is the first to focus on LAIA initiation and maintenance dosing strategies of multiple agents in both a child and adolescent patient population. Further research is required to evaluate the impact of LAIAs on clinical outcomes in this patient population.

Risk of falls or fall-related injuries associated with potentially inappropriate medication use among older adults with dementia.

BACKGROUND: Potentially inappropriate medications (PIMs) are prevalent in older adults with dementia and subsequent falls or fall-related injuries. The present study determined the risk of falls or fall-related injuries associated with PIM use in older adults with dementia. METHODS: The National Health Insurance Service-Elderly Cohort Database 2.0 (NHIS-ECDB 2.0) was used for this self-controlled case series (SCCS) study. This study included 1430 participants who went through exposure and non-exposure periods of PIM application among patients with dementia and experienced outcome events of falls or fall-related injuries between January 2016 and December 2019. The incidence of falls or fall-related injuries during the exposure and post-exposure periods was compared with that during the non-exposure period. Beers Criteria were used to define PIMs in patients with dementia. Negative binomial regression was conducted. The incidence rate ratio (IRR) was used to determine the risk of falls or fall-related injuries. RESULTS: During the exposure periods in which falls or fall-related injuries occurred, the mean number of PIMs among patients with dementia was 3.76 (SD = 2.99), and the most commonly used PIMs among patients with dementia were first-generation antihistamines (n = 283; 59.1%). Compared to the non-exposure period, the adjusted IRR during the exposure period was 1.57 (95% CI = 1.39-1.76). The risk of falls or fall-related injuries was increased when PIM use in patients with dementia was initiated (1-14 days: IRR = 2.76, 95% CI = 2.31-3.28; 15-28 days: IRR = 1.95, 95% CI = 1.48-2.56; ≥ 29 days: IRR = 1.17, 95% CI = 1.01-1.35). Especially, an increased risk of falls or fall-related injuries was associated with greater PIM use among patients with dementia. CONCLUSION: Among older adults with dementia, PIMs significantly increase the risk of falls and fall-related injuries. Therefore, strategies should be developed to manage PIM prescriptions in patients with dementia to prevent falls.

Association between antipsychotics and pulmonary embolism: a pharmacovigilance analysis.

BACKGROUND: Previous studies have documented an increased risk of pulmonary embolism (PE) in patients with schizophrenia taking antipsychotics (APs). However, specific data from real-world studies remain limited. This study aims to investigate the potential relationship between APs and PE. RESEARCH DESIGN AND METHODS: In the Food and Drug Administration Adverse Event Reporting System (FAERS), from the first quarter of 2018 to the first quarter of 2023, all PE cases suspected of being induced by APs were collected for disproportionality analysis, and the reporting odds ratio (ROR) was used to evaluate associations. Mortality, life-threatening events, and hospitalizations were also analyzed for each APs. RESULTS: A total of 1,676 cases of PE related to APs were included. APs were significantly associated with PE (ROR 2.00, 1.91-2.10), including chlorpromazine (n = 41), haloperidol (n = 164), loxapine (n = 37), olanzapine (n = 461), paliperidone (n = 161), quetiapine (n = 526), risperidone (n = 274), aripiprazole (n = 254), and clozapine (n = 234). The median onset time of PE was 29 days. Among all cases, 347 (20.7%) resulted in death, with haloperidol (53.2%) having a higher mortality rate than other APs. CONCLUSIONS: APs may increase the risk of PE in patients with schizophrenia.

Impact of federal antipsychotic use policy in nursing homes on new diagnoses for approved indications in dementia residents.

BACKGROUND: Federal policies targeting antipsychotic use among nursing home (NH) residents may have increased reporting of diagnoses for approved uses, including schizophrenia, Tourette's syndrome, and Huntington's Disease (called "exclusionary diagnoses" because they exclude residents from the antipsychotic quality metric). We assessed changes in new exclusionary diagnoses among long-stay NH admissions specifically with dementia following federal policies. METHODS: Retrospective, quarterly, interrupted time-series analysis (2009-2018) of new long-stay NH residents with dementia and no exclusionary diagnoses reported before NH admission. The National Partnership and the addition of facility level antipsychotic use to the Five Star Quality Rating system were key time exposures. Outcome was quarterly facility level predicted percentage of exclusionary diagnoses within 2 years of admission stratified by NH characteristics. RESULTS: For 264,095 long-stay admissions, mean percentage of new exclusionary diagnoses was 2.2% before the Partnership. After the Partnership, there was an unadjusted increase in the percentage over time (slope change, 0.044, p = 0.018), but the percentage never exceeded 2.9%. The Partnership contributed to a one-time decrease in diagnoses in NHs with an intermediate percentage of Black residents (-1.29%, p = 0.004). Before the Partnership, diagnoses were increasing among not-for-profit relative to for-profit NHs (0.044; p = 0.012), but after the Partnership, the pattern reversed. For-profit NHs saw an increase (+0.034, p = 0.002); not-for-profit NHs experienced a decrease (-0.014, p = 0.039). Quality Rating modifications had no significant effect. CONCLUSIONS: Exclusionary diagnosis reporting among long-stay NH residents with dementia, the group most at risk from antipsychotics, did not increase in response to federal policies. Evaluation of reasons for the observed increase in exclusionary diagnoses among non-dementia NH residents is warranted along with continued attention to how to incentivize the appropriate use of medications in residents with dementia that is crucial for high-quality NH care.

Atypical Antipsychotic-Induced Tardive Dyskinesia in a Middle-Aged Schizophrenic Patient: A Case Report.

Tardive dyskinesia (TD) is a potentially irreversible movement disorder characterized by involuntary, repetitive movements, most commonly affecting the face, tongue, and extremities. It is primarily associated with the long-term use of first-generation (typical) antipsychotics but can also occur with second-generation (atypical) antipsychotics such as aripiprazole. Despite its lower risk profile, aripiprazole can induce TD, as illustrated by a 45-year-old woman with schizophrenia who developed severe involuntary movements after five years of stable treatment with this medication. Her symptoms, including facial grimacing and choreiform movements, were assessed using the Abnormal Involuntary Movement Scale (AIMS), scoring 18, indicative of moderate to severe TD. Following a switch to clozapine and the addition of valbenazine, a VMAT2 inhibitor, the patient experienced significant symptom reduction and improved quality of life. This case emphasizes the need for ongoing monitoring of TD in patients on long-term antipsychotic therapy, even with atypical agents. Effective management strategies, including medication adjustment and the use of VMAT2 inhibitors, are crucial for optimizing patient outcomes and quality of life. Continued research is needed to better understand and address TD in clinical practice.

Efficacy and acceptability of long-acting antipsychotics in acutely ill individuals with schizophrenia-spectrum disorders: A systematic review and network meta-analysis.

To assess the effect of Long-acting injectable (LAI) antipsychotics in acutely ill patients, we systematically searched major databases for randomized controlled trials (RCTs) comparing LAIs with other LAIs, oral antipsychotics, or placebo in acutely symptomatic adults with schizophrenia-spectrum disorders. Data were analyzed with a random-effects network meta-analysis. Co-primary outcomes were efficacy (mean change in psychopathology rating scales) and acceptability (all-cause discontinuations) at study endpoint. Of 25 RCTs, 19 studies tested second-generation LAIs (SGA-LAIs) and six first-generation LAIs (FGA-LAIs). Due to a disconnected network, FGA-LAIs were analyzed separately, with poor data quality. The SGA-LAIs network included 8,418 individuals (males=63%, mean age=39.3 years). All SGA-LAIs outperformed placebo in reducing acute symptoms at study endpoint (median follow-up=13 weeks). They were more acceptable than placebo with the only exception of olanzapine, for which no differences with placebo emerged. Additionally, we distinguished between different LAI formulations of the same antipsychotic to explore potential pharmacokinetic differences. Most formulations outperformed placebo in the very short-term (2 weeks or less), regardless of the need for initial oral supplementation. SGA-LAIs are evidence-based treatments in acutely ill individuals with schizophrenia-spectrum disorders. Findings support the use of SGA-LAIs to manage psychopathology and improve adherence right from the acute phases of illness.
