Description of the evaluation of the CLINFO prototype data management and analysis system, an interactive minicomputer-based system designed to enable clinical investigators to personally explore and analyze their research data. The evaluation was conducted to assess the system's acceptability, to determine benefits that result from its use, and to identify improvements for future systems. Results indicate that CLINFO prototypes and their support personnel are well accepted, and the systems are heavily used at the three sites in which they have been operating. System users have claimed substantial benefits, including time savings, the ability to analyze more data from a single database, reduced data-manipulation errors, and increased publishable results. System costs appear to be acceptable also. It is concluded that a follow-on CLINFO system should have the same functions and mode of operation as the prototype, but some improvements (described in the report) should be incorporated. (See also R-1541, R-1543-3.)
