Antipsychotic prescription patterns in outpatient settings: 24-month results from the Intercontinental Schizophrenia Outpatient Health Outcomes (IC-SOHO) study.

This report describes antipsychotic prescription patterns for outpatients with schizophrenia prescribed olanzapine (n=3,222), clozapine (n=236), risperidone (n=1,117), quetiapine (n=189) or haloperidol (n=256) monotherapy at study entry and treated in a naturalistic, clinical practice setting over 24 months. Predictive factors associated with remaining on monotherapy were also identified. Olanzapine patients had significantly greater odds of remaining on their initial monotherapy compared to other treatment groups, while clozapine or risperidone recipients were more likely to remain on monotherapy, compared to haloperidol patients. Switching antipsychotic medication was more common than addition of another antipsychotic agent, and the most common reason for modifying treatment was lack of effectiveness. The odds of modifying antipsychotic prescription due to intolerability were lower for patients treated with olanzapine, compared to patients treated with risperidone or haloperidol (p<or=.001). However, treatment modification due to patient request was significantly greater for olanzapine-treated patients, compared to risperidone-, quetiapine- or haloperidol-treated patients (p<or=.001).

Non-small cell lung cancer patients with brain metastases treated with first-line platinum-doublet chemotherapy: Analysis from the European FRAME study.

OBJECTIVES We report on a post-hoc analysis of patients with brain metastases from a large prospective observational study of first-line treatment of non-small cell lung cancer (NSCLC). The aim was to describe baseline characteristics of NSCLC patients with brain metastases, understand their first-line treatment and report outcomes attained in real-world settings. MATERIALS AND METHODS This post-hoc analysis included all patients in the European observational FRAME study who had brain metastases at initiation of first-line treatment. Descriptive statistics were used for continuous and categorical variables and survival outcomes were assessed using the Kaplan-Meier approach. RESULTS Our data showed that 17% of patients (263/1564) had spread of the disease to the brain at initiation of first-line treatment. Patients with brain metastases were slightly younger, and more likely to have NSCLC of non-squamous histology than the overall study sample. 34% had received prior palliative radiotherapy to the brain. Our analysis showed a median overall survival (OS) of 7.2 months [95% confidence interval (CI) 6.1-8.2] for all patients with brain metastases treated with first-line platinum-based chemotherapy, ranging from 5.6 months for those treated with gemcitabine plus platinum up to 9.3 months for those treated with pemetrexed plus platinum. Further analysis showed that patients with brain metastases were more frequently treated with pemetrexed platinum-doublet therapy than with any other regimen. CONCLUSIONS Our analysis provides a unique set of real-world data which adds to current understanding about treatment decisions and outcomes for NSCLC patients with brain metastases for whom there is little clinical trial data available.

Treatment with Olanzapine, Risperidone or Typical Antipsychotic Drugs in Asian Patients with Schizophrenia

OBJECTIVE To examine clinical outcomes in Asian patients with schizophrenia receiving monotherapy with olanzapine, risperidone or typical antipsychotics in naturalistic settings. METHOD In this report, data from the first 12 months of the prospective, observational, 3-year Intercontinental Schizophrenia Outpatient Health Outcomes study are presented for patients from participating Asian countries (Korea, Taiwan and Malaysia) who were started on, or switched to, monotherapy with olanzapine (n = 484), risperidone (n = 287) or a typical antipsychotic drug (n = 127) at baseline. RESULTS At 12 months, overall reduction in the score of Clinical Global Impressions-Severity of Illness rating scale was greatest with olanzapine (p < 0.001 vs typical agents), followed by risperidone (p = 0.007 vs typical agents) treatment. Olanzapine treatment was found to have significantly better effects than typical agents on negative and depressive symptom scores, and significantly greater improvements than risperidone on negative and cognitive symptoms. The occurrence of extrapyramidal symptoms was least likely with olanzapine (p < 0.001 vs typical agents, and p = 0.012 vs risperidone), while the estimated odds of tardive dyskinesia were greatest in the typical treatment group (p = 0.046 vs olanzapine, and p = 0.082 vs risperidone). Mean weight increase was greater for olanzapine-treated patients compared with the other agents (p = 0.030 vs typical agents and p < 0.001 vs risperidone). The risk of menstrual disturbance was relatively high with risperidone when compared with olanzapine treatment (p < 0.001). CONCLUSIONS The results of this observational study indicate that, in Asian patients with schizophrenia, olanzapine may offer benefits when compared with typical agents or risperidone. However, the significantly greater odds of weight gain should be considered in the clinical management of olanzapine-treated patients.

A prospective, observational study of the safety and effectiveness of intramuscular psychotropic treatment in acutely agitated patients with schizophrenia and bipolar mania.

This naturalistic, observational pan-European study assessed the safety and early effectiveness of intramuscular (IM) psychotropic treatments in patients with acute agitation suffering from schizophrenia or bipolar mania. One thousand nine hundred and forty of 1945 patients completed the 24-hour observation period after initial IM treatment. Patients from 12 European countries were included (mean age 39 years; 58% male, 66% schizophrenia). IM treatment was at the physicians discretion. The primary objective was to describe the acute tolerability of IM psychotropic therapies in clinical practice, with particular emphasis on EPS. At baseline, 68% of the patients received IM monotherapy, with IM olanzapine most commonly prescribed (36%). During the first 24 hours, 190 (9.8%) patients experienced EPS. The occurrence of EPS was statistically significantly lower in patients treated with IM olanzapine compared to those treated with other IM psychotropic medications (mainly typical antipsychotics and benzodiazepines): acute dystonia: 1.1%, 95% CI 0.5-2.3 and 2.9%, CI 2.0-4.0; akathisia: 2.3%, CI 1.3-3.7 and 5.5%, CI 4.3-6.9; Parkinsonism: 2.9%, CI 1.8-4.4 and 7.8%, CI 6.4-9.4, respectively. Anticholinergic treatment was given to 12% IM olanzapine versus 31% non-olanzapine treated patients. Acute agitation after 24 hours was reduced by 1.68 (95% CI 1.46-1.91) points on the Clinical Global Impression of Severity (CGI-S) in IM olanzapine patients and 1.51 (95% CI 1.30-1.73) points in non-olanzapine patients. Additional psychotropic medication was required for 90% of the patients during the first 24 hours of treatment. Results provide naturalistic evidence for low EPS rates and improvement of agitation with IM psychotropic medications during acute states of patients suffering from acute mania or schizophrenia.

Compliance as a stable function in the treatment course of bipolar disorder in patients stabilized on olanzapine: results from a 24-month observational study

Compliance is a key factor in the maintenance treatment of bipolar disorder. This noninterventional study was conducted to explore factors associated with higher levels of compliance in bipolar patients, all treated in routine clinical settings. Bipolar outpatients (Clinical Global Impression of Severity score ≤3) who had been stabilized with olanzapine mono- or combination therapy for ≥4 weeks were enrolled in the study. Compliance to medication was assessed at baseline and after 3, 6, 9, 12, 18, and 24 months by a physician-rated, 4-point categorical scale using the following classification: noncompliant (patients being compliant to treatment schedule less than 20% of the time) and low (20% to 59% of the time), moderate (60% to 79% of the time), and high (≥80% of the time) levels of compliance. Both baseline and post-baseline factors were used in a generalized estimating equations (GEE) model to predict the likelihood of high compliance. Of 891 eligible patients, 657 patients completed the 24-month observation period. High levels of compliance (≥80%) were observed in 67% of patients at baseline, increasing to 80% in study completers. High compliance at baseline was identified as a strong predictor of compliance during study participation (odds ratio (OR) = 6.9, 95% confidence interval (CI) = 5.0 to 9.5, p < 0.001). Factors associated with high compliance during the study (GEE model) included greater life satisfaction (p = 0.002), better insight into illness (p < 0.001), less work impairment (p = 0.007), and fewer days of inpatient care (p = 0.002). Compliance ratings varied by country (p < 0.001) and duration of post-baseline treatment (p = 0.014). In conclusion, a number of clinical, functional, and social factors were identified as predictors of compliance in patients with bipolar disorder. As compliance is crucial for the long-term management of these patients, more attention should be directed towards compliance itself and factors associated with compliance levels in everyday treatment settings.

Critical evaluation of mixed treatment comparison meta-analyses using examples assessing antidepressants and opioid detoxification treatments.

Comparing multiple treatment options using meta‐analytical methods requires complex statistical methods called mixed treatment comparisons (MTCs). Such methods offer the possibility to summarize data from many clinical trials comparing the different available options. However, those methods are based on a number of assumptions and inherent difficulties that are discussed and illustrated with examples from the psychiatric literature to help readers to understand the strengths and weaknesses of these methods. This review will help enable readers to critically appraise the methodology and results of publications that use MTCs. Copyright

Cisplatin and carboplatin-based chemotherapy in the first-line treatment of non-small cell lung cancer: Analysis from the European FRAME study.

OBJECTIVES To explore patient and disease factors, and reasons behind the physicians choice of platinum backbone for the first-line treatment of non-small cell lung cancer (NSCLC), as observed in a European prospective observational study of patients receiving platinum-based chemotherapy as first-line treatment for advanced or metastatic NSCLC (the FRAME study). Additionally, overall survival (OS) for patients who received cisplatin or carboplatin was evaluated. MATERIALS AND METHODS A post-hoc analysis of the prospective study population was conducted. Baseline characteristics of patients receiving cisplatin versus carboplatin were compared and summarized by propensity score. Survival for matched patients was summarized using the Kaplan-Meier approach. RESULTS Of the 1564 patients who were included in the prospective study, 1520 received either cisplatin (54%) or carboplatin (46%) in combination with pemetrexed, gemcitabine, taxanes or vinorelbine. Patients treated with carboplatin were older than patients receiving cisplatin (mean age 67 versus 61 years; p<0.001), had poorer performance status (p<0.001), and more comorbidities (p<0.001). Cisplatin was most frequently combined with pemetrexed (47%), and carboplatin most frequently with taxanes (31%). Unadjusted median OS estimates for patients from the total prospective study sample were 11.5 months (95% confidence interval [CI] 10.1-12.9) for cisplatin recipients and 9.0 months (95% CI 8.1-10.6) for carboplatin recipients. Median (95% CI) overall survival for the matched cohorts was 10.8 months (8.8-14.3) for cisplatin versus 9.5 months (8.2-11.3) for carboplatin; p=0.086. CONCLUSION This post-hoc analysis illustrated real-life differences in patients with NSCLC prescribed platinum-based first-line treatment, and suggested that baseline patient and disease characteristics were associated with physicians choice of platinum agent, with cisplatin being more frequently prescribed to younger and fitter patients.

Effectiveness and tolerability of schizophrenia treatment in Central and Eastern Europe: results after 1 year from a prospective, observational study (IC-SOHO).

Objective. The Intercontinental Schizophrenia Outpatient Health Outcomes (IC-SOHO) study is intended to complement smaller, shorter-term observational studies and randomised controlled clinical trials in providing information on the treatment of schizophrenia in various geographies that have not been well studied previously. Methods. Interim results after 12 months are presented for a subset of patients from eight Central and Eastern European (CEE) countries initiating or switching to olanzapine, risperidone, or typical antipsychotic monotherapy at Baseline (n=1387). Results. Patients initially prescribed olanzapine and risperidone experienced significantly greater improvements in a broad range of schizophrenia symptom domains compared with patients prescribed typicals. Furthermore, patients in the olanzapine group showed significantly greater improvements in overall and negative symptom domains compared with the risperidone group (all P≤0.05). While patients in the olanzapine group gained more weight than the other two groups, they had significantly lower odds of developing extrapyramidal symptoms, loss of libido, and sexual dysfunction. Patients initially prescribed olanzapine were also significantly less likely to have changed or added antipsychotics during 12 months of treatment compared with the risperidone and typicals groups. Conclusion. In this CEE sample, schizophrenia treatment outcomes after 12 months varied between patients initially prescribed different antipsychotics.
