An Observational Study to Assess Treatment & Outcomes Data in Patients Receiving Long-Acting Injectable Risperidone

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess treatment and outcomes data in patients receiving treatment with long-acting injectable risperidone.

Detailed Description
-----------------
This is an observational (study in which patients/participants are observed) and multicentre (at multiple sites) study. This is one-country arm of a multinational study. This study consists of 2 years of retrospective (a study in which the patients are identified and then documented backward in time and 2 years of prospective (a study in which the patients are identified and then followed forward in time for the outcome of the study) study periods during which medication utilization review will be done, determining medication usage patterns and outcomes associated with the use of risperidone long acting, in clinical practice. Usage of risperidone according to label was recommended during the study. The planned recruitment period will be 6 months. Retrospective observation will be 2 years for hospitalization history and at least 1 year for medication usage. Total duration of prospective observation for each patient with a complete follow-up will be 24 months. Data collection during the follow up period will be scheduled every 3 months ± 2 weeks. In addition, this study is proposed in Belgium to satisfy the demand from Belgian Reimbursement Authorities to collect clinical data on the impact of risperidone long acting on treatment compliance, number of hospitalizations and potential prevention of relapses. Also, this data will provide documentation on switch from oral to parenteral treatment. Data will be pooled from different physicians and/or countries. The objectives of this study are: collect clinical outcome data at the request of the Belgian Reimbursement Authorities; prospectively assess medication usage patterns to document clinical efficacy and long-term treatment outcomes of risperidone long acting, in a naturalistic setting; collect retrospective data, to compare with risperidone long acting; document reasons for initiating risperidone; collect data on switch of treatment to risperidone long acting.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in total length of hospitalization from retrospective to prospective period | Start date, end date of full-time or partial hospitalization will be recorded both in retrospective and prospective study period. | 48 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline to 24 months in Clinical Global Impression (CGI) Scale scores | Patients are rated for overall severity of schizophrenia disorder using the CGI scale (7 point scale) in which 1 = Not Ill and 7 = Extremely Severe. | Baseline, (just before the first injection of long-acting injectable risperidone) to 24 months | 
| Change from baseline to 24 months in Global Assessment of Functioning (GAF) scores | This GAF scale rates the functioning of the patient on a scale of 1 - 100 where 1 - 10 is Persistant danger of severely hurting self or others (eg, recurrent violence) OR persistant inability to maintain personal hygiene OR serious suicidal act with clear expectations of death and 91- 100 is Superior functioning in a wide range of activities, life's problems never seem to get out of hand, is sought out by others because of his of her positive qualities. No symptoms | Baseline to 24 months | 
| Change from baseline to 24 months in clinical deterioration | Clinical deterioration is assessed by evaluating presence or absence of deliberate self injury, suicidal or homicidal ideation, violent behaviour, and increased need in levels of care and increase in CGI by 2 points or more. The maintenance of treatment effect is documented by the time to significant deterioration of the psychotic condition. If signs of significant deterioration occurred more than once within each 3 monthly interval, this is recorded. | Baseline, in 3-monthly intervals (± 2 weeks) for 24 months and Last visit | 
| Change from baseline to 24 months in assessment of remission | Clinical status will be assessed by presence or absence of the following core symptoms: delusions, conceptual disorganization, hallucinatory behavior, mannerisms and posturing, unusual thought content, blunted affect, passive/apathetic social withdrawal, lack of spontaneity and flow of conversation. Score will be given for each symptom as follows: Score 1: Absent, Minimal, Mild; Score 2: Moderate, Moderately severe, Severe, Extreme. Symptomatic remission is defined as a clinical status where for each and every of the symptoms prespecified, a score of 1 can be given for duration of 6 months. | Baseline to 24 months |
