Meeting everyday challenges: antipsychotic therapy in the real world.
Patients with schizophrenia and their physicians face a number of challenges, such as long-term control of symptoms, maintaining cognitive function and subjective well-being, and preventing relapse. While randomised, placebo-controlled trials and open-label extensions can provide valuable information about the long-term efficacy and tolerability of newer antipsychotic agents, they cannot address all the variables that may affect treatment outcome. Factors such as cognitive function, antipsychotic side effects, patients' attitudes to medication and subjective well being can all affect the results of treatment in real-life clinical practice. Moreover, the patient cohorts enrolled in clinical trials are often not reflective of the wider population with schizophrenia. For example, patients with conditions such as anxiety and panic disorders or comorbid substance abuse, as well as those with severe illness and patients from certain ethnic or age groups, may often be excluded from clinical trials. In addition, patients themselves may refuse to participate in placebo-controlled studies because of a fear of being under-treated. Naturalistic studies are, therefore, an important means of providing additional data on the safety and effectiveness of antipsychotic agents in 'real-world' settings. Studies such as the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study, the Schizophrenia Outpatient Health Outcomes (SOHO) study and the Broad Effectiveness Trial with Aripiprazole (BETA) studies, together with large-scale database analyses, are now producing results supplementary to those observed in long-term, open-label extension studies. Such naturalistic studies will continue to provide important data on the real-world effectiveness of atypical antipsychotics with respect to key outcomes such as treatment continuation and prolonged recovery.
