Preferences for attributes of oral antipsychotic treatments: results from a discrete-choice experiment in respondents with schizophrenia or bipolar I disorder

BackgroundAntipsychotic medications are effective treatments for schizophrenia (SZ) and bipolar I disorder (BD-I), but when presented with different treatment options, there are tradeoffs that individuals make between clinical improvement and adverse effects. As new options become available, understanding the attributes of antipsychotic medications that are valued and the tradeoffs that individuals consider when choosing among them is important.MethodsA discrete-choice experiment (DCE) was administered online to elicit preferences across 5 attributes of oral antipsychotics: treatment efficacy (i.e., improvement in symptom severity), weight gain over 6 months, sexual dysfunction, sedation, and akathisia. Eligible respondents were aged 18–64 years with a self-reported clinician diagnosis of SZ or BD-I.ResultsIn total, 144 respondents with SZ and 152 with BD-I completed the DCE. Of those with SZ, 50% identified themselves as female and 69.4% as White, with a mean (SD) age of 41.0 (10.1) years. Of those with BD-I, most identified themselves as female (69.7%) and as White (77.6%), with a mean (SD) age of 40.0 (10.7) years. In both cohorts, respondents preferred oral antipsychotics with better efficacy, less weight gain, no sexual dysfunction or akathisia, and lower risk of sedation. Treatment efficacy was the most important attribute, with a conditional relative importance (CRI) of 31.4% for respondents with SZ and 31.0% for those with BD-I. Weight gain (CRI = 21.3% and 23.1%, respectively) and sexual dysfunction (CRI = 23.4% and 19.2%, respectively) were adverse effects in this study that respondents most wanted to avoid. Respondents with SZ were willing to accept 9.8 lb of weight gain or > 25% risk of sedation for symptom improvement; those with BD-I were willing to accept 8.5 lb of weight gain or a > 25% risk of sedation.ConclusionsIn this DCE, treatment efficacy was the most important attribute of oral antipsychotic medications among respondents with SZ and BD-I. Weight gain and sexual dysfunction were the adverse effects respondents most wanted to avoid; however, both cohorts were willing to accept some weight gain or sedation to obtain better efficacy. These results highlight features that patients value in antipsychotic medications and how they balance benefits and risks when choosing among treatments.

Medication choice and psychosis Hospital readmissions: A two-year comparative study

IntroductionHospital readmissions in psychosis are a critical concern, with medication choice playing a vital role. Oral antipsychotics, though common, rely on patient adherence and can lead to relapses if not followed. Long-acting injectable atypical antipsychotics (LAIAs) provide an alternative, ensuring consistent medication release and reducing relapse risk due to missed doses. Studies indicate that LAIAs result in fewer readmissions due to improved adherence. Tailoring treatment to individual needs is essential. Medication choice significantly influences hospital readmission prevention in psychosis. LAIAs, which could offer greater adherence to treatment and symptom control, present a promising option. Individualized treatment decisions are a priority for long-term recovery.ObjectivesThis study aimed to compare the hospital readmission rates within two years post-discharge among two groups of patients diagnosed with schizophrenia and other psychotic disorders who received either oral antipsychotic treatment or LAIAs.MethodsWe collected sociodemographic and hospitalization data from 155 patients, 90 receiving oral antipsychotics and 65 receiving LAIAs, following their discharge from a psychiatric unit.ResultsThere were 90 patients in the oral treatment group, and 65 in the LAIA group, with 67.6% receiving paliperidone and 26.1% receiving aripiprazole. There were no significant differences in age or gender between the two groups. However, patients in the LAIA group had longer stays in the hospital (M=14.7; SD=10.2 vs M=11.1; SD=6.4; t(153)=2.67; p<.01) and a higher number of prior admissions (M=3.2; SD=3.7 vs M=1.3; SD=3.5; t(153)=2.41; p<.01) compared to the oral antipsychotic group. Additionally, a higher percentage of patients in the LAIA group were diagnosed with schizophrenia (60%) compared to the oral antipsychotic group (24%) (X2(1, N = 155)= 20.4, p<.01). After two years, readmission rates were 66.6% for the oral antipsychotic group and 61.5% for the LAIA group (X2(1, N = 155)= 8.5, p > .05). However, the time to readmission was shorter for patients on oral antipsychotics (M=172.4; SD=162.0) compared to those on LAIAs (M=326.2; SD=211.4; t(153)=3.05; p<.01). Notably, 86.6% of patients on oral antipsychotics were readmitted within the first year, while only 52% of those on LAIAs experienced readmission during the same period (X2(1, N = 155)= 8.5, p = .001).ConclusionsLong-acting injectable antipsychotics (LAIAs) appear to reduce hospital readmissions, with a more pronounced effect in the first few months post-discharge. However, after two years, the readmission rates between LAIAs and oral antipsychotics become comparable. This data suggests that while LAIAs may reduce early readmissions, their long-term effectiveness is on par with oral antipsychotics.Disclosure of InterestNone Declared

Real-World Effectiveness, Economic, and Humanistic Outcomes of Selected Oral Antipsychotics in Patients with Schizophrenia: A Systematic Review Evaluating Global Evidence.

Schizophrenia is a complex, chronic mental health disorder that confers a substantial disease burden globally. Oral antipsychotic treatments (OATs) are the mainstay for treating early and advanced stages of schizophrenia. Our systematic review aimed to synthesize literature describing real-world effectiveness, economic, and humanistic outcomes of OATs (asenapine, brexpiprazole, cariprazine, iloperidone, lumateperone, lurasidone, olanzapine/samidorphan, paliperidone, and quetiapine) for successful management of the disease. PubMed, American Psychological Association PsycINFO (EBSCOhost), and Cumulative Index of Nursing and Allied Health Literature were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting real-world effectiveness, costs, humanistic, behavioral (eg, interpersonal relations, suicide ideation), medication adherence, and product-switching outcomes for selected OATs published in English from January 2010 to March 2022 were identified and evaluated qualitatively. We included 48 studies with different designs providing extensive evidence on schizophrenia. All studies were conducted in countries outside of the United States. In most studies, antipsychotic medications were more effective than placebo, suggesting their value in the management of schizophrenia. Sixteen studies measured the economic outcomes of OATs. Eight studies assessed humanistic outcomes, while one reported behavioral outcomes in three second-generation antipsychotics. Medication adherence was described in two studies, while five studies evaluated product switching. Non-adherence was commonly reported for OATs. Medication non-adherence and treatment discontinuation were predominant factors contributing to the economic burden of schizophrenia. Our research showcased a significant knowledge gap across OATs spanning the humanistic and behavioral outcomes and medication adherence and switching, suggesting a need for robust evidence generation to help clinicians and payers make informed decisions regarding treatment opportunities and cost-effective strategies for patients with schizophrenia.

RWD84 A Comparison of Oral Aripiprazole with an Ingestible Sensor with Oral Atypical Antipsychotic Treatment and Impact on Psychiatric Hospitalizations in Adults with Schizophrenia in a Real-World Care Setting

PCR46 Preferences for Attributes of Oral Antipsychotic Treatments: Survey Results of Patients Living with Schizophrenia or Bipolar I Disorder

This study assessed preferences for attributes of oral antipsychotics among adults with schizophrenia (SZ) or bipolar I disorder (BD-I) and explored potential tradeoffs patients may make between efficacy and tolerability.

MSR93 A Systematic Review of Current Evidence and Gaps on the Impact of Oral Antipsychotic Treatments in Schizophrenia

Schizophrenia, a complex disease with no current cure, affects about 1% of the US population. The burden of schizophrenia is significantly impacted due to heterogeneity observed across medications’ adherence, efficacy, safety, economic, and effectiveness outcomes. The study goal is to provide an in-depth review of studies that describe the clinical, economic, and humanistic outcomes associated with oral medications in schizophrenia.

Predicting psychotic relapse following randomised discontinuation of paliperidone in individuals with schizophrenia or schizoaffective disorder: an individual participant data analysis

Predicting relapse for individuals with psychotic disorders is not well established, especially after discontinuation of antipsychotic treatment. We aimed to identify general prognostic factors of relapse for all participants (irrespective of treatment continuation or discontinuation) and specific predictors of relapse for treatment discontinuation, using machine learning. For this individual participant data analysis, we searched the Yale University Open Data Access Project's database for placebo-controlled, randomised antipsychotic discontinuation trials with participants with schizophrenia or schizoaffective disorder (aged ≥18 years). We included studies in which participants were treated with any antipsychotic study drug and randomly assigned to continue the same antipsychotic drug or to discontinue it and receive placebo. We assessed 36 prespecified baseline variables at randomisation to predict time to relapse, using univariate and multivariate proportional hazard regression models (including multivariate treatment group by variable interactions) with machine learning to categorise the variables as general prognostic factors of relapse, specific predictors of relapse, or both. We identified 414 trials, of which five trials with 700 participants (304 [43%] women and 396 [57%] men) were eligible for the continuation group and 692 participants (292 [42%] women and 400 [58%] men) were eligible for the discontinuation group (median age 37 [IQR 28-47] years for continuation group and 38 [28-47] years for discontinuation group). Out of the 36 baseline variables, general prognostic factors of increased risk of relapse for all participants were drug-positive urine; paranoid, disorganised, and undifferentiated types of schizophrenia (lower risk for schizoaffective disorder); psychiatric and neurological adverse events; higher severity of akathisia (ie, difficulty or inability to sit still); antipsychotic discontinuation; lower social performance; younger age; lower glomerular filtration rate; benzodiazepine comedication (lower risk for anti-epileptic comedication). Out of the 36 baseline variables, predictors of increased risk specifically after antipsychotic discontinuation were increased prolactin concentration, higher number of hospitalisations, and smoking. Both prognostic factors and predictors with increased risk after discontinuation were oral antipsychotic treatment (lower risk for long-acting injectables), higher last dosage of the antipsychotic study drug, shorter duration of antipsychotic treatment, and higher score on the Clinical Global Impression (CGI) severity scale The predictive performance (concordance index) for participants who were not used to train the model was 0·707 (chance level is 0·5). Routinely available general prognostic factors of psychotic relapse and predictors specific for treatment discontinuation could be used to support personalised treatment. Abrupt discontinuation of higher dosages of oral antipsychotics, especially for individuals with recurring hospitalisations, higher scores on the CGI severity scale, and increased prolactin concentrations, should be avoided to reduce the risk of relapse.

Efficacy of oral versus long-acting antipsychotic treatment in patients with early-phase schizophrenia in Europe and Israel: a large-scale, open-label, randomised trial (EULAST)

Schizophrenia is a severe psychiatric disorder with periods of remission and relapse. As discontinuation of antipsychotic medication is the most important reason for relapse, long-term maintenance treatment is key. Whether intramuscular long-acting (depot) antipsychotics are more efficacious than oral medication in preventing medication discontinuation is still unresolved. We aimed to compare time to all-cause discontinuation in patients randomly allocated to long-acting injectable (LAI) versus oral medication. EULAST was a pragmatic, randomised, open-label trial conducted at 50 general hospitals and psychiatric specialty clinics in 15 European countries and Israel. Patients aged 18 years and older, with DSM-IV schizophrenia (as confirmed by the Mini International Neuropsychiatric Interview 5 plus) and having experienced their first psychotic episode from 6 months to 7 years before screening, were randomly allocated (1:1:1:1) using block randomisation to LAI paliperidone, LAI aripiprazole, or the respective oral formulations of these antipsychotics. Randomisation was stratified by country and duration of illness (6 months up to 3 years vs 4 to 7 years). Patients were followed up for up to 19 months. The primary endpoint was discontinuation, regardless of the reason, during 19 months of treatment. We used survival analysis to assess the time until all-cause discontinuation in the intention-to-treat (ITT) group, and per protocol analyses were also done. This trial is registered with ClinicalTrials.gov, NCT02146547, and is complete. Between Feb 24, 2015, and Dec 15, 2018, 533 individuals were recruited and assessed for eligibility. The ITT population included 511 participants, with 171 (33%) women and 340 (67%) men, and a mean age of 30·5 (SD 9·6) years. 410 (80%) of 511 participants were White, 35 (7%) were Black, 20 (4%) were Asian, and 46 (9%) were other ethnicity. In the combined oral antipsychotics treatment group of 247 patients, 72 (29%) patients completed the study and 175 (71%) met all-cause discontinuation criteria. In the combined LAI treatment arm of 264 patients, 95 (36%) completed the study and 169 (64%) met the all-cause discontinuation criteria. Cox regression analyses showed that treatment discontinuation for any cause did not differ between the two combined treatment groups (hazard ration [HR] 1·16, 95% CI 0·94-1·43, p=0·18). No significant difference was found in the time to all-cause discontinuation between the combined oral and combined LAI treatment groups (log rank test χ2=1·87 [df 1]; p=0·17). During the study, 121 psychiatric hospitalisations occurred in 103 patients, and one patient from each of the LAI groups died; the death of the patient assigned to paliperidone was assessed to be unrelated to the medication, but the cause of other patient's death was not shared with the study team. 86 (25%) of 350 participants with available data met akathisia criteria and 70 (20%) met parkinsonism criteria at some point during the study. We found no substantial advantage for LAI antipsychotic treatment over oral treatment regarding time to discontinuation in patients with early-phase schizophrenia, indicating that there is no reason to prescribe LAIs instead of oral antipsychotics if the goal is to prevent discontinuation of antipsychotic medication in daily clinical practice.

Dispersion of cognitive performance test scores on the MATRICS Consensus Cognitive Battery: A different perspective

ObjectivePersons with schizophrenia exhibit greater neurocognitive test score dispersion. Here, we seek to characterize dispersion on the Neurocognitive Composite subtests of the Measurement of Treatment Research to Improve Cognition in Schizophrena Consensus Cognitive Battery (MCCB) and determine the relative effects of different antipsychotic formulations on dispersion and mean performance. MethodIn this post hoc analysis of the DREaM study (NCT02431702), which compared treatment with paliperidone palmitate (PP) long-acting injectable with oral antipsychotic (OAP) treatment over 18 months, dispersion in MCCB neurocognitive subtest performance was calculated for each participant by visit (test occasion). ResultsOver 18 months, mean neurocognitive performance improved in a manner consistent with the expected effects of practice in both groups (p < 0.05); this improvement was observed during the first 9 months (PP: p < 0.05, OAP: p < 0.001), followed by stable performance over the second 9 months (PP: p = 0.821, OAP: p = 0.375). Rates of change did not differ between groups (treatment-by-visit interaction: p = 0.548). In contrast, analyses of dispersion focusing on contrasts between baselines and end points of the first and second 9 months revealed different patterns. Over the first 9 months, dispersion in both groups lessened to a similar extent. However, over the second 9 months, dispersion remained stable in the PP group, whereas neurocognitive performance became significantly more variable in the OAP group (p < 0.01). ConclusionDispersion of neurocognitive test scores provides a different index of cognitive change than that provided by composite scores. Long-term maintenance of therapeutic levels provided by PP over time may limit (relative to oral AP) the extent to which cognitive performance becomes more variable.

Systematic Review of Real-World Treatment Patterns of Oral Antipsychotics and Associated Economic Burden in Patients with Schizophrenia in the United States.

BackgroundSchizophrenia is a chronic mental disorder associated with substantial morbidity and mortality affecting 0.25–1.6% of adults in the USA. Antipsychotic treatment is the standard of care for schizophrenia, but real-world treatment patterns and associated costs have not been systematically reviewed.ObjectiveWe conducted a systematic review to summarize treatment patterns and associated costs related to oral antipsychotic treatment of patients with schizophrenia in the USA.Data SourcesWe searched Medline (via PubMed) and Embase to identify relevant observational studies published from January 1, 2008, to June 1, 2018; costs were converted to 2018 US dollars.Study EligibilityObservational, real-world studies reporting on patterns of treatment and/or associated costs for adult patients with schizophrenia treated with oral antipsychotics in the USA were included.ResultsEighty-one studies were identified. Frequently prescribed oral second-generation antipsychotics were olanzapine (up to 50.9%), risperidone (up to 40.0%), and quetiapine (up to 30.7%). Suboptimal adherence was common across studies. Antipsychotic switching occurred in about half of patients, while antipsychotic combination therapy occurred in nearly 30%; all were associated with increased medication-related costs. Mean annual direct medical costs differed by treatment, with reported costs of $17,115 to $26,138 for patients treated with olanzapine, $18,395 for risperidone, and $17,656 to $28,101 for quetiapine.LimitationsThis systematic review is limited by the variations in definitions of schizophrenia-related clinical terms used between studies and by the inclusion of studies focused on only the US health care system.ConclusionsIn the treatment of schizophrenia, suboptimal adherence, antipsychotic switching, and antipsychotic augmentation were all associated with high costs of care in comparison to patients who were adherent and did not require antipsychotic switching or augmentation. These findings illustrate the need for the development of new treatments that address efficacy and adherence challenges of currently available therapies.Supplementary InformationThe online version contains supplementary material available at 10.1007/s12325-022-02232-z.

Effectiveness of oral versus long-acting antipsychotic treatment early-phase schizophrenia patients: an open-label randomized trial

IntroductionSchizophrenia is a chronic psychiatric illness with periods of remission and relapse. Patients vary in the frequency and severity of relapse, time until relapse and time in remission. Discontinuation of antipsychotic medication is by far the most important reason for relapse. A possible method to optimize medication adherence is to treat patients with long-term, depot medication rather than oral medication.ObjectivesPrimary objective is to compare all cause discontinuation rates in patients with schizophrenia randomized to either one of the two depot medications (aripiprazole depot or paliperidone palmitate) with patients randomized to either one of the two oral formulations of the same medication (aripiprazole or paliperidone) over an 19 month follow-up period.MethodsPragmatic, randomized, open label, multicenter, multinational comparative trial consisting of a 19 month treatment period. Patients aged 18 years or older, having experienced the first psychosis 1-7 years ago, currently meeting DSM-IV-R criteria for schizophrenia. Patients are randomized 1:1:1:1 to paliperidone palmitate, aripiprazole depot, oral aripiprazole or oral paliperidone. The primary outcome is all cause discontinuation.ResultsIn the Intent to Treat sample (n=511), no difference was found in time to ACD between the combined oral and combined depot treatment arms, nor between the four individual treatment arms.ConclusionsEven though the scientific evidence comparing oral and depot medication has been inconsistent, most studies were conducted in rigorous clinical settings, which may have biased those results. In contract, given the pragmatic, open label design of the current trial, the results may be more representative of common daily practice.DisclosureNo significant relationships.

Long-acting injectable antipsychotics for early psychosis: A comprehensive systematic review.

Long acting injectable (LAI) antipsychotics are an alternative to oral antipsychotic (OAP) treatment and may be beneficial for patients in the early stages of schizophrenia. This study aims to provide a comprehensive review on the efficacy of first-generation and second-generation LAI antipsychotics in recent-onset, first-episode, and early psychosis patients. MEDLINE, EMBASE, PsycINFO, and Web of Science Core databases were used to search for studies that used LAIs in early psychosis patients. Studies published up to 06 Jun 2019 were included with no language restrictions applied. Inclusion criteria were a diagnosis of schizophrenia or related disorder, where patients were in their first episode or had a duration of illness ≤5 years. 33 studies were included: 8 RCTs, 4 post-hoc analyses, 2 case reports, and 19 naturalistic studies. The majority of studies evaluated risperidone LAIs (N = 14) and paliperidone palmitate (N = 10), while the remainder investigated fluphenazine decanoate (N = 3), flupentixol decanoate (N = 2), and aripiprazole (N = 1). Two studies did not specify the LAI formulation used, and one cohort study compared the efficacy of multiple different LAI formulations. While the majority of data is based on naturalistic studies investigating risperidone LAIs or paliperidone palmitate, LAIs may be an effective treatment for early psychosis patients in terms of adherence, relapse reduction, and symptom improvements. There is still a need to conduct more high quality RCTs that investigate the efficacy of different LAI formulations in early psychosis patients.

A Noninterventional Cohort Study Assessing Time to All-Cause Treatment Discontinuation After Initiation of Aripiprazole Once Monthly or Daily Oral Atypical Antipsychotic Treatment in Patients With Recent-Onset Schizophrenia.

Introduction: Aripiprazole once-monthly 400 mg (extended-release injectable suspension) is effective in long-term maintenance treatment of schizophrenia based on clinical studies. As study results may not reflect clinical practice, we compared treatment persistence with aripiprazole once-monthly 400 mg versus daily oral atypical antipsychotics in a naturalistic setting.Methods: This was an observational, noninterventional study of patients (aged 18-35 years) with recent-onset schizophrenia (< 5 years post diagnosis) who initiated maintenance treatment with aripiprazole once-monthly 400 mg or any daily oral atypical antipsychotic during a schizophrenia-related hospitalization or within 3 months post hospital discharge (timeframe: July 13, 2017-July 31, 2019). Data were from patient files/obtained during routine visits. Patients were followed for ≤ 12 months or until all-cause treatment discontinuation (including lost to follow-up), whichever came first. Data were analyzed using a sample constructed with inverse probability of treatment weighting (IPTW).Results: Among 357 patients (aripiprazole once-monthly 400 mg: 215, oral atypical antipsychotics: 142), all-cause treatment discontinuation occurred in 87 (41%) of aripiprazole once-monthly 400 mg, 68 (48%) of oral atypical antipsychotic patients over 52 weeks. In the IPTW sample, time to all-cause discontinuation was significantly different between both groups in favor of aripiprazole once-monthly 400 mg (hazard ratio = 1.46; 95% CI, 1.05-2.03; P = .023). Generalizability of results to the overall population with schizophrenia was limited due to incomplete overlap of patient characteristics between cohorts. The primary reason for treatment discontinuation in both groups was voluntary discontinuation by subject (aripiprazole once-monthly 400 mg: 11%; oral atypical antipsychotics: 8%).Conclusions: In a naturalistic setting, younger patients with recent-onset schizophrenia treated with aripiprazole once-monthly 400 mg after hospitalization tended to discontinue treatment later than patients treated with daily oral atypical antipsychotics.Trial Registration: ClinicalTrials.gov identifier: NCT03130465.

PMH13 Healthcare Resource Utilization and Costs before and after Long-Acting Injectable Antipsychotic (LAI) Use in Commercially Insured Young Adults with Schizophrenia

This study examined disease burden before and after initiation of LAIs in commercially insured young adults with schizophrenia. This retrospective observational cohort study used IBM MarketScan Commercial Claims and Encounters Database, 1/1/2008-12/31/2019. Patients with ≥1 inpatient or ≥2 outpatient claims with schizophrenia diagnosis were identified; date of first diagnosis was index date. Patients were aged 18-35 years at index date, with continuous enrollment ≥1-year baseline and ≥1-year follow-up, with ≥1 LAI during follow-up. A pre-post analysis was conducted with paired t-tests to compare relapse (defined as hospitalization or emergency department visit), healthcare resource utilization, and costs before (from index date to LAI initiation) and after LAI initiation (to end of follow-up). Outcomes were reported as Per-Patient-Per-Month (PPPM). We identified 2222 patients who initiated LAIs after index date (mean age=22.9, 70.4% male), with 1421 (64.0%) initiating LAIs after post-index oral antipsychotic treatment. Remaining 36.0% initiated LAIs as index treatment. Average time from index date to LAI initiation was 433.1 days (median 243), and from LAI initiation to end of follow up was 744.0 days (median 630). PPPM relapse event rate was 0.109 before LAI initiation, and 0.073 after LAI initiation (p<0.0001). All-cause direct medical costs (excluding medication), medication costs, and total costs were $4587, $311, and $4898 PPPM before and $2535, $542, and $3078 PPPM after LAI initiation, respectively. All these cost numbers were statistically significantly different (P<0.0001) from before to after LAI initiation. In commercially insured young adults with schizophrenia, use of LAIs was associated with decreased relapse event rate vs the period before LAI initiation. Although medication costs increased in the post LAI period, the cost increase was more than offset by the decreased costs associated with total care. This study demonstrated that LAI treatment for young adults with schizophrenia is associated with significant cost savings to commercial payers.

A Cross-sectional Study of Antipsychotic Drugs Induced Sexual Dysfunction Among Married Males with Remitted Schizophrenia Attending Tertiary Health Care Centre from Central India

Introduction: Schizophrenia is a chronic debilitating disease having a major impact on the sufferers’ lives. Antipsychotic drugs are the mainstay of the treatment of schizophrenia. But, antipsychotics can lead to a variety of sexual dysfunctions among the males with schizophrenia, which may affect their treatment compliance. Aim: To assess the prevalence and the types of sexual dysfunctions among married males with remitted schizophrenia who were on a single oral antipsychotic drug from either class (i.e., typical or atypical type). Materials and Methods: The present cross-sectional study was conducted in a tertiary health-care centre from Central India, with a sample size of 100 married males with schizophrenia who were in the remission phase on a single oral antipsychotic drug. Data were collected by using a convenient sampling method. Socio-demographic profile and clinical variables were recorded in a specific case report form prepared for the study using the Arizona Sexual Experiences (ASEX) scale and the Udvalg for Kliniske Undersogelser (UKU) side-effect rating scale to assess the prevalence and the types of oral antipsychotic drugs induced sexual dysfunctions among study participants. Results: The prevalence of antipsychotic drug induced sexual dysfunction was 54%. The most common type of sexual side-effect of oral antipsychotic treatment was Decreased Sexual Desire/Drive (DSD) as assessed by both ASEX (94.4%) and UKU (63.0%) scales. Sexual dysfunctions like DSD and Ejaculatory Dysfunction (EJD) were associated with the treatment of schizophrenia with typical antipsychotic drugs. Conclusion: The present study shows that the treatment with typical antipsychotics was significantly associated with sexual side-effects. So, routine inquiry during the follow-ups should be done regarding the evaluation of sexual side-effects of antipsychotic agents in order to improve treatment compliance and disease prognosis.

Comparing re-hospitalisation rates in a real-world naturalistic 24-month follow-up of psychotic patients with different treatment strategies: Oral versus LAI antipsychotics.

Non-adherence to antipsychotic treatment is a major issue in the management of severe psychiatric disorders, because it is usually related to future relapses and re-hospitalisations. Long-Acting-Injection (LAI) antipsychotics can be useful to increase treatment adherence in these patients. The aim of the present study was to compare the re-hospitalisation rates of psychotic patients discharged from a psychiatric ward and then, divided into three groups upon the treatment received: LAI antipsychotic, oral antipsychotic at home or oral antipsychotic administered daily by psychiatric nurse staff as patients lived in a long-term care facility. Data on all inpatients consecutively admitted to the Psychiatric Unit of the Nuovo Ospedale Apuano (Massa, Italy), between January 2017 and December 2018, were obtained by the registration record system. Information about eventual re-hospitalisations of these patients, occurred within a 24-month timeframe since discharge, were collected from the same database. In a Kaplan-Meyer analysis, patients treated with LAI antipsychotics showed significantly lower re-hospitalisation rates in the first 24months after discharge than those treated with oral ones. This study highlights the impact of LAI antipsychotics in preventing re-hospitalisation in severe psychotic patients at high risk in a naturalistic setting. The benefits appear relevant also with respect to a controlled long-term oral antipsychotic treatment, however, further studies are needed to develop more tailored intervention strategies in such complex psychiatric population.

P.851Differences in healthcare resource utilization across oral atypical antipsychotic treatments in patients with schizophrenia

The echocardiographic indices have not been validated in critically ill population. The authors investigated the correlation between some echocardiographic and hemodynamic parameters.Prospective, spontaneous, noninterventional observational study.Adult cardiothoracic intensive care unit, single center (Royal Brompton Hospital, London, United Kingdom).Consecutive adult patients admitted to the cardiothoracic intensive care unit for severe respiratory failure, primary cardiocirculatory failure, and post-aortic surgery.Clinical hemodynamic parameters (stroke volume [SV], cardiac output [CO], mean arterial pressure [MAP], and cardiac power index [CPI]) and echocardiographic indices of ventricular function (left ventricular total isovolumic time [t-IVT], mitral annular plane systolic excursion [MAPSE], and left ventricular fraction [LVEF]) were evaluated offline.The study comprised 117 patients (age 57.2 ± 19; 60.6% male). The t-IVT showed an inverse correlation with SV, CO, MAP, and CPI (r –67%; –38%; –45%; –51%, respectively). MAPSE exhibited a positive correlation with SV, CO, MAP, and CPI (r 43%; 44%; 34%; 31%, respectively). LVEF did not show any correlation. In the multivariate analysis the association between t-IVT and hemodynamics was confirmed for SV, CO, MAP, and CPI, with the highest partial correlation between t-IVT and MAP (R = –58%).MAPSE and t-IVT are 2 reproducible and reliable echocardiographic indices of systolic function and ventricular efficacy associated with hemodynamic variables in cardiothoracic critically ill patients, whereas LVEF did not show any correlation.

Pseudo-Resistant Schizophrenia: Non-Adherence to Treatment

Treatment-resistant schizophrenia (TRS) has been defined as the persistence of positive symptoms despite two or more trials of antipsychotic medication of adequate dose and duration. TRS is a serious clinical problem and occurs in approximately 30% of patients with schizophrenia. It is important that patients who do not adequately respond to antipsychotics be reevaluated to exclude or address causes other than non-responsiveness to medication, that is, the possibility of pseudo-resistance. In particular, non-adherence to oral antipsychotic treatment should be monitored to rule out pseudo-resistant cases of TRS. Moreover, patients with TRS who take their medication as required may have subtherapeutic antipsychotic plasma levels, secondary to pharmacokinetic factors. In this paper, we review the concept and exclusion of pseudo-resistance, especially owing to non-adherence or pharmacokinetic factors, and present methods to enhance drug adherence.

T236. A PROGRAM TO INCREASE THE APPROPRIATE USE OF LONG-ACTING ANTIPSYCHOTIC MEDICATIONS IN COMMUNITY SETTINGS

BackgroundAntipsychotic medications are evidence-based treatments for schizophrenia that improve health outcomes and reduce costs. However, rates of non-adherence to oral antipsychotic medications can exceed 60%. We examined whether a simple checklist to identify individuals not receiving optimum benefit from current oral antipsychotic treatment (NOB Checklist) and The Multi-level Facilitation of Long-acting Antipsychotic Medication Program (MAP) could increase the appropriate use of long-acting injectable antipsychotic medication (LAI) in community clinics.MethodsTwo clinics in Texas and two in Ohio changed clinical procedures in one of two ways 1) NOB only clinics--providers used a five-item checklist to identify individuals with schizophrenia on oral antipsychotics who were Not receiving Optimum Benefit from current treatment and may therefore benefit from a switch to LAI. 2) MAP- providers used the NOB checklist AND received MAP; MAP is a novel behavior change intervention designed to improve the identification of individuals who could benefit from LAI, improve their outcomes and reduce inappropriate use of resources associated with poor adherence. MAP targets 3 stakeholder groups 1) the consumer for whom peer specialists showed a video describing shared decision making and how to make a choice between tablets and injections, and provided a balanced shared-decision making tool to assist them in choosing medication route,2) the provider who received academic detailing describing various LAI options, how to make good offers as part of a shared decision making dialogue, and important benefits of LAI including the ability to disentangle efficacy versus poor adherence and to help individuals with cognitive and practical problems that lead to poor adherence, and 3) the administrators who received information on how LAI could improve outcomes for individuals and clinic processes, how to encourage the use of LAI among providers and how to provide regular feedback to providers about prescribing practices. The primary outcome was the percentage of LAI versus oral antipsychotic medication prescribed to individuals with schizophrenia.ResultsHigher NOB checklist scores were associated with an increased provider likelihood of LAI offers and increased consumer acceptance of LAI. All clinics increased use of LAI over time. In Texas, where MAP was fully implemented, the MAP clinic had greater use of LAI over time (eventually reaching about 50% of all antipsychotic use) vs. the NOB only clinic. In Cleveland, the patient stakeholder curriculum was not delivered and there was no significant difference in LAI use between MAP and NOB clinics.DiscussionThe NOB checklist appears to be a useful tool to help identify patients who might be appropriate candidates for LAI and the full MAP program may help clinicians and consumers to work together to optimize the appropriate use of LAI in outpatient settings. Implementation must be customized for clinics and workflows to determine which parts of the MAP program are practical and appropriate. Participation of consumer stakeholders may be essential to delivery of the MAP Program.

Attitudes of European physicians towards the use of long-acting injectable antipsychotics

BackgroundPrescription rates for long-acting injectable (LAI) antipsychotic formulations remain relatively low in Europe despite improved adherence over alternative oral antipsychotic treatments. This apparent under-prescription of LAI antipsychotics may have multiple contributing factors, including negative mental health practitioner attitudes towards the use of LAIs.MethodsThe Antipsychotic Long acTing injection in schizOphrenia (ALTO) non-interventional study (NIS), conducted across several European countries, utilised a questionnaire that was specifically designed to address physicians’ attitudes and beliefs towards the treatment of schizophrenia with LAI antipsychotics. Exploratory principal component analysis (PCA) of feedback from the questionnaire aimed to identify and characterize the factors that best explained the physicians’ attitudes towards prescription of LAIs.ResultsOverall, 136/234 solicited physicians returned fully completed questionnaires. Physicians’ mean age was 48.5 years, with mean psychiatric experience of 20.0 years; 69.9% were male, 84.6% held a consultant position, and 91.9% had a clinical specialty in general adult care. Most physicians considered themselves to have a high level of clinical experience with LAI antipsychotics (77.2%), with an increased rate of LAI antipsychotics prescription over the last 5 years (59.6%). Although the majority of physicians (69.9%) declared feeling no difference in stress levels when offering LAI compared to oral antipsychotics, feelings of ‘no/more stress’ versus ‘less stress’ was found to influence prescription patterns. PCA identified six factors which collectively explained 66.1% of the variance in physician feedback. Multivariate analysis identified a positive correlation between physicians willing to accept usage of LAI antipsychotics and the positive attitude of colleagues (co-efficient 3.67; p = 0.016).ConclusionsThe physician questionnaire in the ALTO study is the first to evaluate the attitudes around LAI antipsychotics across several European countries, on a larger scale. Findings from this study offer an important insight into how physician attitudes can influence the acceptance and usage of LAI antipsychotics to treat patients with schizophrenia.
