An overview of the interactive, minicomputer-based CLINFO prototype system for the storage, retrieval, and analysis of medical research data. The prototype is designed especially to meet the information processing needs of clinical investigators and to be used as a tool for investigating the efficacy of introducing such systems into clinical research centers. One prototype is operational at the Baylor College of Medicine in Houston, Texas; another will be installed at the University of Washington in Seattle in the summer of 1976. The CLINFO prototype is used by investigators and staff personnel at a TV-like display terminal. It provides facilities for describing an individual's study, entering time-oriented data about patients, creating patient subsets, retrieving specified data values, and effecting a number of commonly-used statistical analyses. The prototype evolves as experience is gained; its experimental use will lead to specifications for hardware, software, support personnel and operating procedures. (Based on R-1543.)
