Multicenter trials as a measure for improving the quality of clinical decisions

The terms quality assurance and multicenter clinical trials encompass many elements and the relationships between these elements are complex. The principles of quality assurance can be applied to the research methodology used in clinical trials. In turn, the results of these clinical trials can be used to establish standards for clinical care. Finally, the efficacy of the application of those standards in improving clinical care can be evaluated in the context of a clinical trial.
