Time course of antipsychotic treatment response in schizophrenia: Results from a naturalistic study in 280 patients

2010

To describe the course of positive and negative symptoms during inpatient treatment and examine remission and response rates under routine clinical care conditions.Two hundred and eighty inpatients with schizophrenia (DSM-IV criteria) were assessed with the Positive and Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the symptom-severity component of the consensus criteria (Remission in Schizophrenia Working Group) as a rating of three or less in the relevant PANSS items at discharge, and response as a reduction of at least 20% in the PANSS total score from admission to discharge.The mean duration of in…

Influencing factors and predictors of early improvement in the acute treatment of schizophrenia and schizophrenia spectrum disorder.

2011

Abstract Background To examine the influencing factors and predictors of early improvement in schizophrenia patients. Methods 370 patients suffering from a schizophrenia spectrum disorder were examined within a naturalistic multicenter study. Early improvement was defined as a ≥30% PANSS total score reduction within the first two treatment weeks, response as a ≥50% improvement of the PANSS total score from admission to discharge and remission according to the consensus remission criteria. Baseline and course-related variables such as positive, negative and depressive symptoms, side effects, functioning and subjective well-being were examined regarding their explanatory value for early impro…

Response trajectories in "real-world" naturalistically treated schizophrenia patients.

2011

Abstract Background To date, research has identified distinct antipsychotic response trajectories yet focussing on data from randomized-controlled trials (RCTs). Therefore, the heterogeneity of response in “real-world” schizophrenia patients is still unknown. Methods Antipsychotic response was evaluated in 399 patients suffering from a schizophrenia spectrum disorder within a naturalistic multicenter study of the Competence Network on Schizophrenia using latent class regression. Baseline and illness-related variables were compared between the different trajectory classes as well as currently proposed outcome definitions (early improvement, response, remission) using univariate tests. In ord…

Insight in schizophrenia–course and predictors during the acute treatment phase of patients suffering from a schizophrenia spectrum disorder

2012

AbstractBackgroundTo analyse insight of illness during the course of inpatient treatment, and to identify influencing factors and predictors of insight.MethodsInsight into illness was examined in 399 patients using the item G12 of the Positive and Negative Syndrome Scale (“lack of insight and judgement”). Ratings of the PANSS, HAMD, UKU, GAF, SOFAS, SWN-K and Kemp's compliance scale were performed and examined regarding their potential association with insight. The item G12 was kept as an ordinal variable to compare insight between subgroups of patients.ResultsAlmost 70% of patients had deficits in their insight into illness at admission. A significant improvement of impairments of insight …

2015

Significant changes of schizophrenia patients during inpatient treatment were evalutaed and compared to established outcome criteria. The concept of reliable and clinically significant change methods was applied to three hundred and ninety-six patients suffering from a schizophrenia spectrum disorder. First, information on whether or not the change of the patient's condition is sufficient in order to declare that it is beyond a measurement error or random effect (= reliable change) was evaluated and in a second step it was observed if the reliable change was clinically meaningful (= clinically significant change). Different Positive and Negative Syndrome Scale for Schizophrenia (PANSS) thre…

Prediction of symptom remission in schizophrenia during inpatient treatment

2007

Standardized consensus criteria for remission in schizophrenia were recently proposed. The present study applied the symptom-severity component of these criteria to a sample of inpatients in order to determine the rates of remission during inpatient treatment and to explore predictors of remission.A total of 288 inpatients from a multi-centre follow-up programme who fulfilled ICD-10 criteria for schizophrenia were included in the present analyses. PANSS ratings at admission and at discharge from hospitalization were used to examine remission status. Clinical and sociodemographic variables at admission were tested for their ability to predict remission at discharge.In total, 55% of the sampl…

AbstractObjectiveTo examine the predictive validity of early improvement in a naturalistic sample of inpatients and to identify the criterion that best defines early improvement.MethodsTwo hundred and forty-seven inpatients who fulfilled ICD-10 criteria for schizophrenia were assessed with the Positive And Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the recently proposed consensus criteria, response as a reduction of at least 40% in the PANNS total score from admission to discharge.ResultsReceiver operating characteristic (ROC) analyses showed that early improvement (reduction of the PANSS total sco…

Defining and predicting functional outcome in schizophrenia and schizophrenia spectrum disorders.

Abstract Background: To assess criteria and to identify predictive factors for functional outcome. The criteria should cover all domains proposed by the Remission in Schizophrenia Working Group. Method: PANSS ratings were used to evaluate the symptomatic treatment outcome of 262 inpatients with schizophrenia spectrum disorders within a naturalistic multicenter trial. Functional remission was defined as a GAF score > 61 (Global Assessment of Functioning Scale), SOFAS score > 61 (Social and Occupational Functioning Scale) and a SF-36 mental health subscore > 40 (Medical Outcomes Study—Short Form Health Survey). Multivariate logistic regression and CART analyses were used to determine valid cl…

Depression during an acute episode of schizophrenia or schizophreniform disorder and its impact on treatment response

2008

The aim of the present study was to examine the relevance of depressive symptoms during an acute schizophrenic episode for the prediction of treatment response. Two hundred inpatients who fulfilled DSM-IV criteria for schizophrenia or schizophreniform disorders were assessed at hospital admission and after 6 weeks of inpatient treatment using the Positive and Negative Syndrome Scale (PANSS) and the Hamilton Rating Scale for Depression (HAM-D). Depressive symptoms showed positive correlations with both positive and negative symptoms at admission and after 6 weeks, and decreased during 6 weeks of treatment. Pronounced depressive symptoms (HAM-D score> or =16) were found in 28% of the sample a…

Add-on Antidepressants in the Naturalistic Treatment of Schizophrenia Spectrum Disorder – When, Who, and How?

2017

Abstract The aim of this study was to evaluate antidepressant add-on treatment within the acute treatment of schizophrenia spectrum disorder patients. Antidepressant add-on was evaluated in 365 patients within a naturalistic multicenter study. Patients with/without antidepressant add-on were compared regarding clinical and treatment-related variables, response and remission, and remission of depressive and negative symptoms. The efficacy of antidepressant add-on treatment was furthermore analyzed applying marginal structure models. Twenty-three percent of the patients received antidepressant add-on for a mean duration of 50.28 (33.42) days. Patients with the diagnosis of a schizoaffective d…

2019

Despite being recommended for use in clinical trials, the consensus remission criteria were found to leave patients with persisting symptoms, relevant areas of functional impairment and a decreased sense of wellbeing. Therefore, to evaluate the appropriateness of the schizophrenia consensus criteria, a definition of remission based on the Clinical Global Impression Scale (CGI) was developed and remitter subgroups were compared.239 patients with a schizophrenia spectrum disorder were evaluated regarding their remission status after inpatient treatment. Remission in schizophrenia was defined according to the symptom-severity component of the consensus criteria by Andreasen et al. and a CGI ba…
