Databases and the future of clinical trials in bladder cancer.

As clinical trials continue to expand and evolve to include a wider range of collected information, the amount and variety of information available to clinical researchers has concurrently grown. This article describes a range of means to address this complexity and to accommodate the collection, storage, and integration of this information based on current approaches in biomedical informatics. By reviewing these current approaches, and drawing examples from actual practice within the clinical informatics community, a range of potential solutions and their potential impacts are discussed.
